Referring to FIG. 2-5, among others, a ring wing 105 of a submersible glider 100 is shown. The ring wing 105 can be coupled at an end of the component 140. For example, the component 140 can have a length 205. An outer surface 215 can taper along the length 205. For example, the component 140 can be, or include, a frustrum or have a frustum shape. The frustum can start at a plate 210 where the frustum has a largest outer diameter and extend to towards the ring wing 105 or away from the middle portion 115 or front portion 110. The frustum shape can extend to a coupling with the ring wing 105, where the frustum shape has a smallest outer circumference.

The component 140 can be at least partially hollow. A shaft, arm, linkage, or elongated member 220 can be at least partially disposed within the component 140. The member 220 can include a portion 230, a portion 405, and a portion 410. The portions 230, 405, or 410 can be integrally formed, or coupled together at ends of the portion 230, 405, or 410 via a weld, connector, snap, bolt, or telescoping apparatus. The member 220 can be formed from aluminum, steel, or a plastic.

The member 220 can extend from a first side of the plate 210 through an opening 225 in the plate 210 to a second side of the plate 210. The second side of the plate 210 can be opposite the first side of the plate 210. The opening 225 can have a circular or cylindrical shape. An actuator 235 such as a motor, gear box, linkage apparatus, or a solenoid can be coupled with the plate 210. The actuator 235 can rotate the member 220 along a longitudinal axis of a portion 230 of the member 220. The longitudinal axis of the portion 230 can be parallel with a longitudinal axis of the component 140 or a longitudinal axis 150 of the glider 100.

The portion 230 can include a first end that couples with the actuator 235. The actuator 235 can exert or apply a rotational force on the first end of the portion 230 to cause the member 220 to rotate about the longitudinal axis of the portion 230. A second end of the portion 230 can be coupled with a first end of a portion 405 of the member 220. The portion 405 and the portion 230 can be perpendicular to each other. The portion 405 and the portion 230 can meet at an angle. The angle can be 90 degrees. The angle can be 80-100 degrees. The angle can be 75-105 degrees. The angle can be less than 75 degrees. The angle can be greater than 105 degrees. The portion 405 can extend from an end of the portion 230 to an end of the portion 410. The portion 405 can extend away from a stabilizer 415 or away from a surface of the portion 230. The portion 405 can extend at an angle perpendicular to a longitudinal axis of the portion 230, a longitudinal axis of the portion 140, or a longitudinal axis 150 of the glider 100.

A portion 410 can extend from an end of the portion 405 towards the ring wing 105. The portion 410 can extend in a direction parallel with the portion 230, with a longitudinal axis of the portion 230, with a longitudinal axis of the member 140, or a longitudinal axis 150 of the glider 100. The portion 405 and the portion 410 can meet at an angle. The angle can be 90 degrees. The angle can be 80-100 degrees. The angle can be 75-105 degrees. The angle can be less than 75 degrees. The angle can be greater than 105 degrees. The portion 410 can extend to a pin 420. The pin 420 can couple the member 220 with the ring wing 105.

The ring wing 105 can include an outer ring 240. The outer ring 240 can be disposed about or around at least a portion of an inner ring 245. The ring wing 105 can be integrally formed, or can be formed from discrete components that are coupled, fastened, or connected together. The outer ring 240 can have an airfoil or hydrofoil shape, surface, or structure. The inner ring 245 can have an airfoil or hydrofoil shape, surface, or structure. The outer ring 240 and/or the inner ring 245 may be configured to provide lift (e.g., hydrostatic lift) in one or more directions relative to the flow/displacement of a surrounding medium. The ring wing 105 can include wings, spokes, or members 250 that extend between the outer ring 240 and the inner ring 245. The members 250 can extend from an inner surface of the outer ring 240 to an outer surface of the inner ring 245. The ring wing 105 is shown to include five members 250. The members 250 can be spaced in equal distances from each other or in unequal distances from each other. The members 250 can have an airfoil or hydrofoil shape or structure, e.g., configured to provide lift (e.g., hydrostatic lift) in one or more directions relative to the flow/displacement of a surrounding medium.

The members 250 can extend at an angle 265 from the outer ring 240 to the inner ring 245. The members 250 can extend from the outer ring 240 in a direction towards the middle portion 115 or the front portion 110. An angle 265 formed between an inner surface of the outer ring 240 and a trailing edge of a member 250 can be 110-120 degrees. The angle 265 can be 105-125 degrees. The angle 265 can be less than 105 degrees. The angle can be greater than 125 degrees. The angles 265 formed between the inner surface of the outer ring 240 and the trailing edge of the members 250 can be equal or unequal. The members 250 have a wing shape, such as an airfoil shape or a hydrofoil shape.

A trailing boundary 255 of the outer ring 240 can be offset from an trailing boundary 260 of the inner ring 245. For example, the end or edge 255 of the outer ring 240 can extend past an end or edge 260 of the inner ring 245 in a direction away from the middle portion 115 or front portion 110 of the glider 100. Furthermore, a leading boundary 425 of the inner ring 245 can be offset from a leading boundary 430 of the outer ring 240. The leading boundary 425 can extend in a direction towards the middle portion 115 or the front portion 110.

The inner ring 245 can include a first portion 435. The inner ring 245 can include a second portion 440. The outer diameter of the first portion 435 can be greater than an outer diameter of the second portion 440. The second portion 440 can extend from an end of the first portion 435 towards the plate 210, the actuator 235, the member 230, the middle portion 115, or front portion 110 of the glider 100. At least a portion of the second portion 440 or at least a portion of the first portion 435 can extend into the member 140. For example, the outer surfaces 215 of the member 140 can meet at an opening through which at least a portion of the first portion 435 or at least a portion of the second portion 440 can extend through. The first portion 435 can be partially disposed within the member 140. The second portion 440 can be fully disposed within the member 140.

A hinge or pin 450 can enable the ring wing 105 to rotate about an axis. For example, the pin 450 can be inserted through the first portion 435 of the inner ring 245 and the portion 410 of the member 220. The ring wing 105 can rotate about a longitudinal axis of the pin 450. The outer diameter of the first portion 435 or the second portion 440 can be less than the outer diameter of the opening of the member 140 such that the ring wing 105 can rotate on the pin 450.

The ring wing 105 can pivot, move, tilt, and/or rotate about or along a vertical axis 145. For example, the ring wing 105 can tilt left or right to act as a rudder and provide direction control. The ring wing 105 can pivot about the vertical axis 145 to steer the glider 100 through the aqueous medium (e.g., while the buoyancy, weight distribution and/or center-of-gravity of the glider relative to the aqueous medium creates thrust/motion on the glider from displacement forces of the aqueous medium). For example, the ring wing 105 can pivot to steer the glider 100 laterally, e.g., left or right. For example, the actuator 235 can rotate the member 220 via a coupling between the actuator 235 and an end of the member 220. The member 220 can rotate about a longitudinal axis of the portion 220. Because the member 220 rotates about the stabilizer 415, the portions 405 and 410 can move relative to the stabilizer 415, causing the ring wing 105 to steer the glider 100.

In some implementations, the ring wing 105 can pivot, move, tilt or rotate about a horizontal axis. The horizontal axis can be perpendicular the vertical axis 145 and the longitudinal axis 150. The ring wing 105 can pivot about the horizontal axis to control a glide angle of the glider 100 or angle of attack of the glider 100. The ring wing 105 can pivot about the horizontal axis to cause/aid the glider 100 to ascend or descend through the aqueous medium. Tilting the ring wing 105 about a horizontal axis can provide for improved ascent or descent of the vehicle in the aqueous medium, or otherwise control the rate of ascent or descent in the aqueous medium.

An outer surface of the outer ring 240 can taper at an angle 505. The outer surface of the outer ring 240 can taper in a direction parallel to the tapering of the cone 215. The angle 505 can be an angle formed between an outer surface of the outer ring 240 and an outer surface of the middle portion 115. The angle 505 can be the same as or equal to the angle 155. The angle 505 can be 17-19 degrees. The angle 505 can be 16-20 degrees. The angle 505 can be less than 16 degrees. The angle 505 can be greater than 20 degrees.

Referring now to FIG. 6, among others, the submersible glider 100 including a ring wing 105 and a buoyancy engine 130 is shown. The buoyancy engine 130 can include at least one pump 605, at least one valve, at least one bladder, or at least one ballast tank. The buoyancy engine 130 can be controlled or operated by the data processing system 135 to change the buoyancy of the glider 100. The data processing system 135 can operate the buoyancy engine 130 to increase the buoyancy of the glider 100 or decrease the buoyancy of the glider 100. The buoyancy engine 130 can cause the glider 100 to rise or fall within the aqueous medium by changing the weight of the glider 100. The data processing system 135 can operate the buoyancy engine 130 to adjust a buoyancy of the glider 100 to meet a particular angle of attack or glide angle.

The buoyancy engine 130 can add a fluid to a compartment or release the fluid from the compartment within the fuselage or within the glider 100 to adjust the buoyancy of the glider. For example, the data processing system 135 can operate the buoyancy engine 130 to open or close a valve to allow an aqueous medium to enter a bladder or compartment of the buoyancy engine 130 or exit the bladder. The data processing system 135 can operate the buoyancy engine 130 to open a valve to allow an aqueous medium to enter a bladder to cause the glider 100 to become heavier and thus less buoyant. The pump 605 can be disposed within the middle portion 115. A first bladder can be disposed within the component 140. A second bladder can be disposed within the middle portion 115. The pump 605 can pump a liquid or gas that is lighter than the aqueous medium into the first bladder to dispel or displace the aqueous medium from the bladder, causing the glider 100 to become lighter and therefore more buoyant. The pump 605 can pump the liquid or gas from the second bladder into the first bladder. For example, the gas or liquid pumped into the bladder can push the aqueous medium out of the bladder and out of the glider 100 into the surrounding aqueous medium. For example, the pump 605 can pump an oil into the bladder to cause the glider 100 to become lighter and more buoyant. In some embodiments, multiple bladders located at different sections of the glider can be controlled/filled differentially or otherwise, to change/control a buoyancy, center-of-gravity and/or weight distribution of the glider. This can be used to control/adjust an orientation, direction, tilt, motion and/or displacement of the glider with respect to the aqueous medium.

The buoyancy engine 130 can include at least one sled 610. The sled 610 can be a platform, box, container, or other component. The data processing system 135 can be coupled with, fixed with, attached to, disposed within, or disposed on the sled 610. The glider 100 can include a power source 615. The power source 615 can be or include at least one battery 615, at least one super capacitor, at least one generator. The power source 615 can be coupled with, fixed with, attached to, disposed within, or disposed on the sled 610. The sled 610 can move on/along at least one rail 620.

The data processing system 135 can control at least one actuator, such as a motor, to move the sled 610 forward towards the front portion 110 of the glider 100 or backwards towards the rear portion 120 of the glider 100. In this regard, the buoyancy engine 130 can change the distribution of weight of the glider 100 along a length or the longitudinal axis 150 of the glider 100. For example, the buoyancy engine 130 can move the sled 610 forwards to place more weight forward towards the front portion 110 of the glider 100, or move the sled 610 backwards to place more weight rearwards towards the rear portion 120 of the glider 100. By changing the weight placement/distribution within the glider 100, the buoyancy engine 130 can move or control a center-of-gravity of the glider 100 to cause the glider 100 to ascend or descend through the aqueous medium.

The power source 615 can power at least one actuator, such as a motor or pump, of the glider 100. For example, via at least one electrical connection, cable, or component, the power source 615 can deliver, provide, or transfer power to the buoyancy engine 130 to adjust the buoyancy or center-of-gravity of the glider 100 in the aqueous medium. For example, the power source 615 can power the buoyancy engine 130 to control the buoyancy of the glider 100. The pump 605 can operate based on power received from the power source 615 to displace aqueous medium from a bladder of the glider 100. A valve can be operated based on power received from the power source 615 to allow an aqueous medium to enter the glider 100. Furthermore, power from the power source can be used by a motor to move the sled 610 forwards or backwards within the glider 100.

Furthermore, the power source 615 can power the actuator 235. For example, via at least one electrical connection, cable, or component, the power source 615 can deliver, provide, or transfer power to the actuator 235 to rotate or move the ring wing 105 about the vertical axis 145. For example, via the power provided by the power source 615, the data processing system 135 can operate the actuator 235 to steer the glider 100 laterally.

Referring now to FIG. 7, among others, an example vehicle 700 deploying a launch container 710 including the submersible glider 100 is shown. The glider 100 can be launched or deployed into an aqueous medium 705 from a vehicle 700. The aqueous medium 705 can be the ocean, a lake, a flooded area, a canal, or any other body of liquid, such as water. The vehicle 700 can be a maritime vehicle or a marine vehicle. The vehicle 700 can be a boat, a ship, a submarine, or another glider. The vehicle 700 can be an aerial vehicle, such as a plane, a rotorcraft, or a drone. The glider 100 can be launched from a mobile or stationary platform. The glider 100 can be launched from land, the shore, or a dock. The vehicle 700 can carry at least one launching apparatus 715 and at least one launch container 710 including gliders 100. The vehicle 700 can deploy one or multiple gliders 100 via launching containers 710 and the launching apparatus 715 as the vehicle 700 traverses, moves across, moves over, or sails on the aqueous medium 705.

The glider 100 can be loaded, inserted into, disposed in, or placed in a launch container 710. The launch container 710 can be an SLC. The SLC can be an A-Size launch container. The launch container 710 can have a cylindrical or tubular shape. The launch container 710 can be larger than, or slightly larger than, the glider 100 such that the glider 100 can fit within a cavity, opening, space, or tube of the launch container 710. In order to fit within the launch container 710, the glider 100 may not include any lateral wings or members that extend outwards from an outer surface of the middle portion 115 or the front portion 110. The glider 100 may not include any lateral wings that extend outwards more than 10 centimeters. The glider 100 may not include any lateral wings that extend outwards more than 5 centimeters. The glider 100 may not include any lateral wings that extend outwards more than 3 centimeters.

One more multiple launch containers 710 can be loaded into a launching apparatus 715. The launching apparatus 715 can be disposed on, or installed on, the vehicle 700. The launching apparatus 715 can launch the launch container 710 from the vehicle 700 to the aqueous medium 705. Once in the aqueous medium 705, the launch container 710 can open and the glider 100 can be deployed from, exit, or move out of the launch container 710. The data processing system 135, or a data processing system of the launch container 710, can cause the glider 100 to be deployed from the launch container 710. The data processing system 135 can cause the glider 100 to deploy out of the launch container 710 responsive to the launch container 710 being launched to or into the aqueous medium 705. In some implementations, a mechanical apparatus or a mechanism can detect that the launch container 10 has been launched, and can cause the launch container 710 to open and the glider 100 to deploy from the launch container 710.

Once the glider 100 is deployed from the vehicle 700 or from the launch container 710, the glider 100 can configure or deploy one or multiple components of the glider 100 for operation. For example, the glider 100 can include a mechanism 720, such as a spring, piston, or other compressible member that provides a force. The mechanism 720 can be coupled with the stern of the fuselage of the glider 100. For example, the mechanism 720 can be coupled to a rear of the rear portion 120 or a rear of the middle portion 115. The mechanism 720 can move, extend, or deploy the ring wing 105 from a first position (e.g., a stowed position) to a second position (e.g., a deployed position). The mechanism 720 can cause the ring wing 105 to move between the first position and the second position, for example, to any position between the first position and second position. For example, the mechanism 720 can move the ring wing 105 from a first position a first distance from the end of the middle portion 115 to the second position a second distance from the end of the middle portion 115 greater than the first distance. The mechanism 720 can move the ring wing 105 backwards along the longitudinal axis 150 away from a direction of travel of the glider 100.

The mechanism 720 can include a pressure switch. In some implementations, the sensor 125 can be or include a pressure sensor or pressure switch. The pressure switch can detect an increase in pressure subsequent to the glider 100 being launched into the aqueous medium 705. Responsive to detecting a pressure increase, e.g., a pressure of the aqueous medium 705 on the glider 100 exceeding or satisfying a threshold, the pressure switch can activate the mechanism to deploy the ring wing 105. For example, the mechanism 720 can be in a locked position or state. The pressure switch can unlock the mechanism 720 responsive to the pressure satisfying or exceeding the threshold, to cause the ring wing 105 to be moved or extended from the first position to the second position. The pressure switch can cause the ring wing 105 to move between the first position and the second position, for example, to any position between the first position and second position.

Referring now to FIG. 8, among others, an example of hydrostatic, drag, and lifting forces on a submersible glider including a ring wing are shown. Hydrostatic forces 805 acting on the glider 100 along the vertical axis 810 can include weight or wet weight (W) and buoyancy (B). The weight can be varied with the buoyancy engine 130 to cause the glider 100 to ascend or descend. A pitch or a glide path or angle 815 of the glider 100 can be controlled by the buoyancy engine 130. The glide angle 815 can be an angle between a direction of travel 820 of the glider 100 and the vertical axis 810, where the glider 100 travels along the direction 820 at some velocity 825. The vertical axis 810 can be an angle perpendicular to a horizon. An angle between the longitudinal axis 150 of the glider 100 and the direction of travel 820 can be an angle of attack 830. The heading of the glider 100 can be controlled via actuator of the ring wing 105 about a single axis, such as the vertical axis 145. A lifting force 835 and a drag force 840 are also shown in FIG. 8. The lifting force 835 can be a force perpendicular to a surface of the middle portion 115 of the glider. The lifting force 835 can be a total lifting force of the glider 100. The drag force 840 can be a total drag of the glider 100 opposite to a direction of travel 820 of the glider 100.

FIG. 8 illustrates the lift 845 and drag 850 created by the ring wing 105. The drag 850 is shown along the longitudinal axis 150 of the glider 100. The lift 845 is shown perpendicular to the longitudinal axis 150 of the glider 100. The lift 845 can be created by the outer ring 240, the inner ring 245, or the members 250. The drag 850 can be created by the outer ring 240, the inner ring 245, or the members 250. The lift 855 and the drag 860 caused by the fuselage of the glider 100 (e.g., the front portion 110, the middle portion 115, and the rear portion 120) are also illustrated in FIG. 8. The drag 860 is shown along the longitudinal axis 150 of the glider 100. The lift 855 is shown perpendicular to the longitudinal axis 150 of the glider 100.

Referring now to FIG. 9, an example chart 900 of velocity versus glide angle of a submersible glider 100 including a ring wing 105 and a submersible glider 100 including a conventional wing is shown. The conventional wings can extend at an angle perpendicular to the longitudinal axis 150 outward from an outer surface of the middle portion 115. The results shown in the chart 900 can be based on an A-size glider 100 including an overall length of 36 inches, a fuselage diameter of 4 and ⅞ inches, a transom stern diameter of 1 inch, and an afterbody cone angle of 18 degrees. The ring wing 105 of the glider 100 can include a diameter of 4.5 inches and a chord of 1.5 inches. The conventional wings can include a wing span of 24 inches and a chord of 2 inches.

In the chart 900, the vertical axis can be a lateral velocity component 825, while the horizontal axis can be glide angle 815 for angles of attack 830 up to 11.25 degrees. The value do can be a reference velocity for a wingless configuration where the angle of attack 830 and the glide angle 815 are zero (e.g., the glider 100 is moving straight down along the vertical axis 810). The chart 900 includes a trend 905 for glide angle versus velocity for the glider 100 including the ring wing 105. The chart 900 includes a trend 910 for glide angle versus velocity for the glider including a conventional wing. The chart 900 indicates that the glider 100 that does not include conventional wings and instead includes a ring wing 105 has a superior ability to attain horizontal velocity. In contrast, the glider including the conventional wings incurs the additional drag of the conventional wings without taking advantage of the lift provided by the conventional wings to reduce angle of attack 830 and the associated drag. The chart 900 further indicates that the glider 100 including the ring wing 105 can have sufficient horizontal velocity to station keep in currents typical of coastal areas, without needing conventional wings.

The weight and center-of-gravity of the glider 100 can be controlled by the data processing system 135 operating the buoyancy engine 130 to achieve an ideal or optimal operating scenario for lateral movement. In the ideal operating scenario, the speed 825 may reach a top speed. In the chart 900, the top speed 825 of the glider 100 can be achieved at a glide angle 815 of 51.9 degrees and an angle of attack 830 of 5.5 degrees. At this top speed, the drag of the fuselage can be 0.43 newton (N). The lift provided by the fuselage can be 0.23 N. The weight 805 of the glider 100 can 10.87 N while the buoyancy can be 9.87 N. The lift provided by the ring wing 105 can be 0.6 N while the drag of the ring wing 105 can be 0.10 N. This operating scenario can be an ideal or optimal operating point, where the weight minus the buoyancy is 1 N, providing operational gliding performance for the glider 100. In this regard, the forces on the glider 100 at the ideal lateral progress can have a 1N wet weight including normal and axial hydrodynamic forces on the fuselage and ring wing plus weight and buoyancy. The forces indicated can result in a pitching moment of zero.

Referring now to FIG. 10, among others, an example method 1000 of a submersible glider 100 including a ring wing 105 is shown. At least a portion of the method 1000 can be performed by the glider 100, the data processing system 135, the buoyancy engine 130, the ring wing 105, the launch container 710, the launching apparatus 715, or the vehicle 700. At least a portion of the method 1000 can be performed by a manufacturing apparatus, system, or individual. The method 1000 can include an ACT 1005 of providing a glider including a ring wing. The method 1000 can include an ACT 1010 of deploying a glider. The method 1000 can include an ACT 1015 of adjusting buoyancy and a center-of-gravity of a glider.

At ACT 1005, the method 1000 can include providing or deploying a glider 100 including a ring wing 105. The method 1000 can include manufacturing or creating a middle portion 115. The method 1000 can include installing or mounting components into the middle portion 115, e.g., the sled 610, the rails 620, the data processing system 135, the buoyancy engine 130, the pump 605. The method 1000 can include pressurizing the middle portion 115. The method 1000 can include pressurizing the middle portion 115, such as a pressure hull, to 0.9-1.1 atmospheres of pressure. The method 1000 can include pressurizing the middle portion 115, such as a pressure hull, to 0.8-1.2 atmospheres of pressure. The method 1000 can include pressurizing the middle portion 115, such as a pressure hull, to a pressure less than 0.8 atmospheres of pressure. The method 1000 can include pressurizing the middle portion 115, such as a pressure hull, to a pressure more than 1.2 atmospheres of pressure.

The method 1000 can include installing, disposing, activating and/or placing a sensor 125 within the front portion 110. The method 1000 can include coupling the sensor 125 with the data processing system 135. The method 1000 can include coupling the front portion 110 with a front of the middle portion 115. The method 1000 can include coupling the component 140 with the rear of the middle portion 115. For example, an end including a largest or greatest diameter of a cone 140 can be coupled with the rear end of the middle portion 115. A ring wing 105 can be coupled with an end of the cone 140. The ring wing 105 can be coupled with a small or smallest diameter end of the cone 140.

The method 1000 can include manufacturing or creating the ring wing 105. The method 1000 can include manufacturing the ring wing 105 as a single component with multiple parts or members integrally formed. The method 1000 can include manufacturing the ring wing 105 in separate or discrete parts, which can be coupled, connected, or joined together with rivets, snaps, adhesives, bolts, or screws. The ring wing 105 can be manufactured to have an outer ring 240 and an inner ring 245. The outer ring 240 and the inner ring 245 can have hydrofoil or airfoil shapes that generate lift based on liquid flow or displacement over or across the outer ring 240 or the inner ring 245. At least one member 250 can extend between the outer surface of the inner ring 245 and an inner surface of the outer ring 240. The members 250 can be airfoil or hydrofoil shapes, and generate lift based on liquid flow or displacement over or across the members 250.

At ACT 1010, the method 1000 can include deploying the glider 100. The method 1000 can include installing, disposing, or placing the glider 100 within a launch container 710. The launch container 710 can have a cylindrical shape that the glider 100 can fit within. An operator, machine, or robotic assembly can load the glider 100 into the launch container 710. The launch container 710 can be loaded, installed, or placed into the launch container 710. The launch container 710 can be deployed, launched, or shot out by the launching apparatus 715. The launching apparatus 715 can deploy the launch container 710 to or into the aqueous medium 705. The glider 100 can be deployed from or exit the launch container 710 into the aqueous medium 705. For example, a pressure switch or other detector can sense, detect, or identify when the launch container 710 or glider 100 enters the aqueous medium or reaches a particular depth in the aqueous medium. The pressure switch can cause the container 710 to open so that the glider 100 can exit the container 710 into the aqueous medium 705.

At ACT 1015, the method 1000 can include adjusting buoyancy and a center-of-gravity of the glider 100. The data processing system 135 can operate the buoyancy engine 130 to increase or decrease the weigh or buoyancy of the glider 100. For example, the buoyancy engine 130 can cause a bladder or area of the glider 100 to take on weight (or reduce buoyancy) by opening a valve to allow the aqueous medium 705 to enter the bladder. This can cause the glider 100 to descend. To cause the glider 100 to rise, the data processing system 135 can cause the glider to decrease in weight (or increase buoyancy) by operating a pump 605 to dispel the aqueous medium 705 from the bladder out of the glider 100. Compressed air or oil can be pumped into the bladder to dispel the aqueous medium 705 from the bladder to cause the glider 100 to decrease in weight and thus rise.

Furthermore, the glider 100 can adjust the center-of-gravity of the glider 100 to control the glide angle 815 and/or orientation of the glider 100. The glide angle 815 of the glider 100 can be controlled by controlling one of the center-of-gravity or the weight of the glider 100. The glide angle of the glider 100 can be controlled by controlling both the center-of-gravity and the weight of the glider 100. The data processing system 135 can operate motor or other actuator that causes the sled 610 to move forward towards the front portion 110 of the glider 100 or away from the rear portion 120 of the glider. The data processing system 135 can operate the motor or other actuator to cause the sled 610 to move backwards towards the rear portion 120 of the glider 100 or away from the front portion 110 of the glider 100. The data processing system 135 can operate the actuator 235 to turn, rotate, or move the ring wing 105 about the vertical axis 145. This can control the lateral direction of the glider 100.

The data processing system 135 can operate the glider 100 to station keep, or stay next to or near a set location or within a set geographical region. For example, the data processing system 135 can cyclically cause the glider 100 to have steep glide angles 815 to descend to a particular depth, and then ascend to another depth. This cycling between a small glide angle 815 to descend (near zero glide angles 815), and a large glide angle 815 to rise (near 180 degrees glide angle 815) can cause the glider 100 to stay within the area for an extended duration of time. In this regard, the glider 100 can station keep for an extended duration of time, e.g., days, weeks, or months. This can be significantly longer than the station keeping of a sonobuoy, which may become un-operational or sink to the bottom of the aqueous medium 705 after only hours of operation.

The data processing system 135 can operate the actuator 235 to position the ring wing 105 to increase or optimize the velocity of the glider 100. For example, the data processing system 135 can collect a sensor data set from sensors (such as the sensor 125) or operational pieces of information. For example, the data processing system 135 can collect information such as depth, pressure, current velocity 825 of the glider 100, glide angle 815 of the glider 100, etc. The data processing system 135 can determine a control command based on the information. For example, the control command can be an indication to move the ring wing 105 about horizontal axis or vertical axis. The control command can indicate a position to move the ring wing 105 to. Responsive to generating the command, the data processing system 135 can operate the actuator 235 to rotate, move, or turn the ring wing 105 to the position based on the control command and thus increase the velocity 825 of the glider 100. The data processing system 135 can iteratively, adaptively, or dynamically position the ring wing 105 until a maximum velocity 825 is identified.

Referring now to FIG. 11, among others, is an example computing architecture of a data processing system 135 of a submersible glider 100 is shown. The data processing system 135 can include or be used to implement a data processing system or its components. The data processing system 135 can include at least one bus 1125 or other communication component for communicating information and at least one processor 1130 or processing circuit coupled to the bus 1125 for processing information. The data processing system 135 can include one or more processors 1130 or processing circuits coupled to the bus 1125 for processing information. The data processing system 135 can include at least one main memory 1110, such as a random access memory (RAM) or other dynamic storage device, coupled to the bus 1125 for storing information, and instructions to be executed by the processor 1130. The main memory 1110 can be used for storing information during execution of instructions by the processor 1130. The data processing system 135 can further include at least one read only memory (ROM) 1115 or other static storage device coupled to the bus 1125 for storing static information and instructions for the processor 1130. A storage device 1120, such as a solid state device, magnetic disk or optical disk, can be coupled to the bus 1125 to persistently store information and instructions.

The data processing system 135 can be coupled via the bus 1125 to a display 1100, such as a liquid crystal display, or active matrix display. The display 1100 can display information to a user. An input device 1105, such as a keyboard or voice interface can be coupled to the bus 1125 for communicating information and commands to the processor 1130. The input device 1105 can include a touch screen of the display 1100. The input device 1105 can include a cursor control, such as a mouse, a trackball, or cursor direction keys, for communicating direction information and command selections to the processor 1130 and for controlling cursor movement on the display 1100.

The processes, systems and methods described herein can be implemented by the data processing system 135 in response to the processor 1130 executing an arrangement of instructions contained in main memory 1110. Such instructions can be read into main memory 1110 from another computer-readable medium, such as the storage device 1120. Execution of the arrangement of instructions contained in main memory 1110 causes the data processing system 135 to perform the illustrative processes described herein.
