Patexia is looking for descriptions of an airframe, subfloor structure, and bowl hull structure for a rotary wing aircraft or helicopters, hybrid rotorcraft, UAV drone rotorcrafts.
Submitted documents describing this system must be:
- filed or published before 30/12/2013
- not on the known references list
The entire submission must describe a subfloor structure for a rotary wing aircraft with the following components:
- An airframe (2)
- A subfloor structure (3) that records the distance vector for each link within the network
- A bowl hull structure (18) connected to both air-frame (2) and subfloor structure (3)
This contest is part one of a two-part contest for a prior art search for European Patent 2889212 with a focus on claims 1, 6, 8, 9, and 15.
|1||Is the reference either a US patent filed, a foreign patent published, or a non-patent document published before December 30, 2013?||T/F|
|2||Does the reference show a subfloor structure for a rotary wing aircraft or helicopters, hybrid rotorcraft, UAV drone rotorcrafts?||5|
|3||Does the reference show an airframe extended along XZ plane, including and delimiting the subfloor structure with an outer bottom shell, a construction framework, and floor panels defining a floor surface at least locally perpendicular to an elevation direction of the XZ plane?||15|
|4||Does the reference further show the subfloor structure having a pair of longerons extending at least locally along the X axis and at least a pair of crossbeams defined by inner and outer ribs and at least locally extending along Y direction orthogonal to the XZ plane?||15|
|5||Does the reference show the outer bottom shell having a bottom central portion delimited transversally by the two longerons, and the outer bottom shell further having at least a pair of outer side shells extending outwards aside the bottom central portion?||15|
|6||Does the reference show the subfloor structure comprises: - An integral subfloor bowl hull made of a U-shaped one-piece, made of a composite material, or a single pieced metal and - Defining at least: the bottom central portion, two lateral transition regions and two upward web portions, having the bottom central portion and the integrated upward web portions constructed in a one shot curing step the integral subfloor bowl hull spans over at least 2/3 of an overall longitudinal dimension of the subfloor structure, below the floor surface?||25|
|7||Does the reference further show the upward web portions integrally extending from the bottom central portion by forming the two longerons and being integrated to the integral subfloor bowl hull together with the two lateral transitional locations?||10|
|8||Does the reference further show the lateral transition regions being opposed one to the other relatively to the XZ plane, each transition region being continuously merged with the bottom central portion and one of the two upward web portions, the outer side shells being attached to the integral subfloor bowl hull in the vicinity of the lateral transition regions?||15|
This is a Prior Art Search contest aimed at determining if a patent idea was known and publicly available before a patent was filed.
+5 bonus points will be awarded for non-patent literature and for foreign language references.
This contest will close on Sunday, March 27th, 2016 at 11:59 PM PST.
