Patent number: 8646720Abstract: The invention is a modular vehicle having an air vehicle that can be coupled to cargo containers, land vehicles, sea vehicles, medical transport modules, etc. In one embodiment the air vehicle has a plurality of propellers positioned around a main airframe, which can provide vertical thrust and/or horizontal thrust. The propellers are mounted on supports which have an airfoil shape to generate additional lift. One or more of the propellers may be configured to tilt forward, backward, and/or side-to-side with respect to the airframe.Type: GrantFiled: May 10, 2011Date of Patent: February 11, 2014Inventor: Donald Orval Shaw

Patent number: 8640988Abstract: An aircraft landing gear comprising: an arm mounted to a pivot and carrying one or more wheel assemblies; and a composite leaf spring which is coupled to the arm and arranged to provide a resilient biasing force which opposes rotation of the arm about the pivot. The arm can be made relatively stiff in comparison with the leaf spring, so that load is transferred directly into the pivot without a large amount of bending of the leg. The leaf spring shock absorber typically has a reduced part count compared with a conventional oleo-pneumatic shock absorber. By forming the leaf spring from a composite material, its weight is significantly reduced in comparison with a conventional metal spring, making it suitable for use on a relatively large aircraft.Type: GrantFiled: February 24, 2009Date of Patent: February 4, 2014Assignee: Airbus UK LimitedInventor: Robert Ian Thompson

Patent number: 8528863Abstract: A laminated wing structure includes at least one layer of metal material and at least one layer of a shape memory polymer (SMP) material. The SMP is heated to a temperature in its glass transition band Tg to roll the wing around the air vehicle into a stored position. The metal layer(s) must be thin enough to remain below its yield point when rolled up. In preparation for launch, the SMP material is thermally activated allowing the strain energy stored in the layer of metal material to return the wing to its deployed position at launch. Once deployed, the SMP cools to its glassy state. The SMP material may be reinforced with fiber to form a polymer matrix composite (PMC). SMP may be used to provide shear strain relief for multiple metal layers. By offloading the motive force required to return the wing to its original deployed position from the SMP to the metal, the polymer does not acquire a permanent set and the wing may be deployed accurately.Type: GrantFiled: May 10, 2009Date of Patent: September 10, 2013Assignee: Raytheon CompanyInventors: Terry M. Sanderson, Brian J. Gowler, David R. Sar, Thomas P. McCreery

Patent number: 8485473Abstract: According to the invention, the method comprises exposing a surface (3) sensitive to relative wind and monitoring the thermal flow variations between the surface (3) and the aerodynamic flow, said variations resulting from that of the forced-convection thermal exchange coefficient between the surface (3) and the aerodynamic flow depending on the rime or ice build-up, using the temperature sensor (12) under the surface (3), considering that stripping occurs by the flow of an ice layer formed on the surface (3) if it is detected, preferably after heating by at least one heater (4), that there is a brisk rise of the flow at a temperature close to 0° C., and supplying after the detection of ice stripping, a signal indicating the presence of rime or rime conditions. A cooler (5) may cool the surface (3) for anticipating the formation of ice with a heating process.

Patent number: 8408490Abstract: An oblique wing aircraft (1) designed for reduced surface area to volume ratio. The aircraft has an oblique wing comprising a forward swept wing segment (27) on one side of the wing and an aft swept wing segment (29) on the opposite side of the wing. A center oblique airfoil section (25) connects the forward and aft swept wing segments. The center oblique airfoil section has a larger chord near its centerline than the chords of either of the forward or aft swept wing segments. The chord of the center oblique airfoil section tapers down more rapidly than the forward or aft wing segments as the center oblique airfoil section extends outboard toward the forward and aft swept wings. The center oblique airfoil section is not shaped solely to function as a circular fairing to fill the gap between an oblique wing and a fuselage at different oblique wing angles, nor is it a second wing in an X wing configuration. Preferably, the aircraft is an all-wing aircraft.Type: GrantFiled: August 29, 2008Date of Patent: April 2, 2013Assignee: Advanced Product Development, LLCInventor: William R McDonnell
