Abstract: An electro-pneumatic de-icer for an airfoil includes an electrically-powered compressor for compressing air, an air-storage tank for storing compressed air, a source of negative pressure, an airfoil pneumatic boot, and a control valve located between 1) the air-storage tank, 2) the source of negative pressure, and 3) the pneumatic boot for cycling between compressed air to inflate the pneumatic boot and negative pressure to deflate the pneumatic boot for cracking accumulated ice on the airfoil. An airfoil de-icing method lacking engine bleed air extraction includes compressing air with an electrically-powered compressor, storing high-pressure air from the compressor in an air-storage tank, delivering high-pressure air from the air-storage tank to inflate a pneumatic boot located along an airfoil, providing a negative-pressure source, deflating the pneumatic boot with the negative-pressure source, and alternating between inflating and deflating the pneumatic boot for cracking accumulated ice on the airfoil.

Abstract: Embodiments of the present disclosure include a curved planar wingtip for a straight wing and a curved planar wingtip for a swept wing of an aircraft. The curved planar wingtips include a member that extends from the end of the wing in a direction aft of the wing trailing edge while remaining substantially planar with the wing. The curved planar wingtips curve continuously from leading and trailing edges of the wing to form a tip located aft of the wing. Other embodiments of the curved planar wingtip are configured for a horizontal or vertical tail. Yet another embodiment includes a curved wingtip that extends aft of a trailing edge of the wing by a distance greater than the curved wingtip extends above a top surface of the wing.

Abstract: A seat configured for removably securing to a track includes a quick-release fitting for operation by hand to releasably secure a bottom end of a seat leg to a floor-mounted track for facile adjustment and removal of the seat. A threaded stud includes a shaft portion arranged through an opening in an end of the seat leg and a radially extending base. A pivot mechanism has a through-hole arranged around the shaft portion of the threaded stud. A first transverse member and a second transverse member each extend transversely from the pivot mechanism in opposite directions along a pivot axis. A lever is configured to pivot about the pivot axis causing the threaded stud to move up or down via the pivot mechanism, which raises and lowers the radially extending base for alternately securing the seat leg to the track and releasing the seat leg from the track.

Abstract: A system and method for simulating a structure is disclosed. An adjustable interior mockup for simulating a structure has a base with a first elongated side and a second elongated side, the first elongated side being nonadjacent the second elongated side; and an adjustable frame secured to the base. The adjustable frame includes a plurality of girder members secured along the first and second elongated sides to form an arc; a plurality of brackets; a plurality of arms having a latch attached to one end; and a sheet of fabric. The girders are securely fastened along the first elongated side of the base at predetermined intervals; the brackets are secured to the girders; the arms are received by the brackets and adjustably anchored to the girders via a fastener; and the latches engage the sheet of fabric, thus pulling the fabric into a shape that resembles the structure.

Abstract: An expedited preflight readiness system for aircraft includes a power source having one or more battery modules for storing electrical power. An integrated controller is electrically and communicatively coupled with the power source for monitoring and controlling the power source to provide electrical power to aircraft subsystems. A mobile device is communicatively coupled with the integrated controller for communicating instructions to the integrated controller for initiating preflight readiness of the aircraft and for monitoring preflight readiness. A method for preconditioning an aircraft includes determining a state-of-charge of an APU and activating an environmental control subsystem for preconditioning the aircraft by adjusting a current temperature according to a preconditioning profile based on one or more of a target temperature, a target time, the current temperature, an outside air temperature, an amount of energy, and a state-of-charge of the APU.

Abstract: A distributed auxiliary-power-unit (APU) system for an aircraft includes one or more battery modules for storing electrical power, and a plurality of racks distributed throughout the aircraft for receiving the one or more battery modules to electrically connect with an electrical subsystem of the aircraft. A plurality of hot-swappable racks are adapted to receive the battery modules for electrically and communicatively coupling with the electrical subsystem and an integrated controller. A remote interface is communicatively coupled with the integrated controller for receiving user-input to direct electrical power from the battery modules to one or more subsystems of the aircraft. A number of battery modules installed is based on an amount of electrical power planned for a given flight of the aircraft.

Abstract: A ground spoiler control architecture for aircraft includes a primary control architecture for providing a roll function, a speed-brake function and a ground spoiler function, and a secondary control architecture for providing the ground spoiler function in the event of a failure of the primary control architecture. The primary and secondary control architectures each include multiple actuators for actuating ground spoilers via independent and redundant signaling paths. Redundant hydraulic accumulators provide pressurized hydraulic fluid to the actuators. A ground spoiler control method includes determining whether the aircraft is on the ground based on the throttle-level-angle and whether any two wheels speeds are active or whether the main landing gear is weighted. Deployment of at least a portion of the ground spoiler panels occurs when and when the main landing gear is on the ground and the aircraft is in a landing configuration based on the throttle-level-angle.

Abstract: Disclosed are systems and methods for maintaining bulk fuel temperatures in an aircraft. In one aspect, a recirculation system causes fuel to be delivered from a relatively low point near the feed hopper of each tank on the aircraft to one or more outboard locations of the wings. Once there, the fuel, due to gravity, flows back over the lower skin of the wing in channels back towards the fuselage, thus cooling the fuel. In other aspects, control systems are disclosed that coordinate the recirculation based on fuel levels in the tanks and fuel temperatures. The control systems also utilize a fuel scavenge system to maintain acceptable temperatures in the tanks.

Abstract: Disclosed is a modular seat for aircraft. The system has a frame that is able to be interconnected with other frames laterally. Since each lateral frame has the same pivot points (when viewed from the side), the linked seats rotate together. The seats also include buckle lugs which enable a particular seat to be used on either side of the aircraft.
