Abstract: An aircraft is operable to transition between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft includes an airframe having first and second wings with first and second pylons extending therebetween forming a central region. A two-dimensional distributed thrust array and a flight control system are coupled to the airframe. A nose cone and an afterbody are each selectively coupled to the airframe. In a cargo delivery flight configuration, the nose cone and the afterbody are coupled to the airframe such that the nose cone and the afterbody each extend between the first and second wings and between first and second pylons to form a cargo enclosure with an aerodynamic outer shape. In a minimal drag flight configuration, the nose cone and the afterbody are not coupled to the airframe such that air passes through the central region during flight.

Abstract: An anti-torque assembly for a helicopter includes a plurality of fans pivotably mountable to the tail boom. The fans have fan blades rotatable about a fan axis. One or more of the plurality of fans is pivotable relative to the tail boom to a first configuration. The fan axes of the fans in the first configuration have an upright orientation and are operable to one or both of pitch and roll the helicopter. Different fans of the plurality of fans are operable to generate thrust to provide anti-torque to the helicopter. The anti-torque assembly is thus capable of providing both anti-torque to the helicopter and changing its attitude.

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.

Abstract: A transmission support for securing a transmission to a rotorcraft includes two side beams each including a roof beam portion configured to be secured to structural elements of the rotorcraft cabin, and a pylon beam portion extending from the roof beam portion toward the other of the side beams. The pylon beam portion is configured to engage the transmission upon the transmission being received between the side beams. The support further has cross beams extending between and interconnecting the two side beams. The side beams and cross beams are part of a monolithic structure. A method of manufacturing the transmission support is provided.

Abstract: ABSTRACT OF THE INVENTION A hybrid propulsion system for a tiltrotor aircraft comprises one or more engines that provide thrust whenever the tiltrotor aircraft is in a first forward flight mode, one or more electrical or hydraulic power sources, and two or more pylon assemblies. Each pylon assembly houses one or more electric or hydraulic motors connected to the one or more electrical or hydraulic power sources and a proprotor. All or part of each pylon assembly is rotatable. The proprotors provide lift whenever the tiltrotor aircraft is in a vertical takeoff and landing mode and a hover mode, and provide thrust whenever the tiltrotor aircraft is in a second forward flight mode.

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 aircraft includes a wing and a rotor pod mounted to the wing. The rotor pod includes a body having a forward end and an aft end. A propeller is mounted to the body of the rotor pod at the forward end. A control surface is mounted to the body of the rotor pod between the forward and aft ends and extends outwardly from the body. The control surface is displaceable relative to the body between a first control configuration and a second control configuration to control an attitude of the aircraft. The control surface in the first control configuration is closer to the propeller than the control surface in the second control configuration.

Abstract: An aircraft includes a fuselage, and a wing extending from the fuselage along a spanwise axis. A section of the wing is rotatable about the spanwise axis. A ducted fan is mounted to the section of the wing. The ducted fan has a hub configured to be drivingly engaged by an engine. The hub is rotatable about a fan axis. Blades protrude from the hub between roots mounted to the hub and tips radially spaced from the hub. A duct circumferentially extends about the fan axis and is mounted to the tips of the blades to rotate with the blades about the fan axis. The section of the wing and the ducted fan are rotatable about the spanwise axis between a hover mode in which the fan axis is substantially perpendicular to a ground, and an aircraft mode in which the fan axis is substantially parallel to the ground.
