Abstract: A coaxial rotor system for a rotorcraft includes a mast, a top rotor assembly and a bottom rotor assembly. The top rotor assembly is coupled to the distal end of the mast. The bottom rotor assembly includes a motor configured to provide rotational energy to the mast, thereby rotating the top rotor assembly. The bottom rotor assembly experiences a torque reaction force responsive to the motor rotating the mast such that the top and bottom rotor assemblies counter rotate.

Abstract: An energy absorbing landing system for an aircraft having a fuselage includes landing legs rotatably coupled to the fuselage configured to outwardly rotate when receiving a landing load having a magnitude. The energy absorbing landing system also includes an energy absorption unit coupled to the fuselage and cables coupling the energy absorption unit to the landing legs. The energy absorption unit is configured to selectively apply a resistance to the outward rotation of the landing legs via the cables based on the magnitude of the landing load, thereby absorbing the landing load when the aircraft lands.

Abstract: Embodiments are directed to systems and methods for controlling a tiltrotor aircraft using a flight control system. A flight control computer is configured to control aircraft effectors in response to inputs from inceptors. The flight control computer stores instructions for controlling aircraft effectors. The instructions cause the flight control computer to perform the steps of converting a signal representing longitudinal motion of a first inceptor into a fore-and-aft translational rate command for the tiltrotor aircraft; converting a signal representing lateral motion of the first inceptor into a side-to-side translational rate command for the tiltrotor aircraft; converting a signal representing longitudinal motion of a second inceptor into a height rate command for the tiltrotor aircraft; and converting a signal representing lateral motion of the second inceptor to a yaw rate command for the tiltrotor aircraft.

Abstract: A tiltwing aircraft convertible between a vertical takeoff and landing flight mode and a forward flight mode includes a fuselage, a tiltwing rotatably coupled to the fuselage and a convertible tailboom and landing gear system rotatably coupled to the fuselage. The tiltwing is rotatable between a substantially vertical position in the vertical takeoff and landing flight mode and a substantially horizontal position in the forward flight mode. The convertible tailboom and landing gear system is rotatable between a landing gear position in the vertical takeoff and landing flight mode and a tailboom position in the forward flight mode. The convertible tailboom and landing gear system includes skids and linkages that rotatably couple the skids to the fuselage. The skids are positioned below the fuselage in the landing gear position and extend aft of the fuselage in the tailboom position.

Abstract: An tiltrotor aircraft includes a rotor position control system (RPCS). The RPCS includes an electric motor configured to selectively rotate the rotor blade, a target marker kinematically associated with the rotor blade, a sensor configured to sense a position of the target marker, and a flight control computer configured to selectively control the electric motor in a normal mode of operation in which the rotor blade provides thrust and a phase lock mode of operation in which the electric motor maintains the rotor blade in a predetermined indexed position.

Abstract: A multimodal unmanned aerial system includes a fuselage forming a payload bay, a control wing forward of the fuselage including a first plurality of propulsion assemblies and a primary wing aft of the fuselage including a second plurality of propulsion assemblies. The primary wing has a greater wingspan than the control wing. The multimodal unmanned aerial system includes linkages rotatably coupling the fuselage to the control wing and the primary wing. The fuselage, the control wing and the primary wing are configured to synchronously rotate between a vertical takeoff and landing flight mode and a forward flight mode. The fuselage, the control wing and the primary wing are substantially vertical in the vertical takeoff and landing flight mode and substantially horizontal in the forward flight mode.
