An aerial vehicle includes a propulsion unit and a fuselage unit. The propulsion unit includes a rotary shaft extending in a first direction and thrust producing mechanisms provided at both ends of the rotary shaft and produces a propulsion force for flying in air. The fuselage unit is suspended from the propulsion unit below the rotary shaft, has a center of gravity at a position below the rotary shaft, is configured to freely rotate around the rotary shaft, and is capable of storing an article.

A method of deploying an unmanned aerial vehicle (UAV) includes launching a UAV and deploying at least one portion of a wing assembly from a stowed configuration to a deployed configuration in which the at least one portion of the wing assembly extends away from a body of the UAV. Deploying the portion of the wing assembly, which may be an outboard portion of a wing assembly, includes deflecting an aerodynamic control surface on the at least one portion of the wing assembly to cause an aerodynamic force to move the portion of the wing assembly into the deployed configuration without assistance from a spring or motor. An unmanned aerial vehicle (UAV) includes a UAV having a body and a plurality of wing assemblies carried by the body, at least a portion of a wing assembly is deployable using aerodynamic forces and without assistance form a spring or motor.

An assembly is provided for an aircraft. This aircraft assembly includes an aircraft control surface. The aircraft control surface includes a first skin, a second skin and a support structure laterally between and connected to the first skin and the second skin. The support structure includes a spar, a first stiffener and a second stiffener. The spar extends spanwise within the aircraft control surface. The first stiffener extends longitudinally within the aircraft control surface to the spar. The second stiffener extends longitudinally within the aircraft control surface to the spar. An actuator receptacle projects longitudinally into the aircraft control surface from a base of the aircraft control surface to the spar. The actuator receptacle extends spanwise within the aircraft control surface between the first stiffener and the second stiffener.

A Short Takeoff and Landing (STOL) aircraft has a fuselage with an axis and an engine providing thrust, a first aileron at an end of a first wing, a second aileron at an end of a second wing, a first slot having a length through the first wing proximate the first aileron, orthogonal to the axis; a second slot having a length through the second wing proximate the second aileron, orthogonal to the axis; a first electric motor in the first wing driving a first two-blade propeller in the first slot, a second electric motor in the second wing driving a second two-blade propeller in the second slot, and a control mechanism enabling a user to drive the first and second electric motors in a same rotary direction, to reverse the rotary direction, and to drive the first and second motors at a same rpm.

An aircraft comprises an aircraft structure, a flight control surface attached to the aircraft structure, and a local hydraulic power pack disposed proximal to the flight control surface. The local hydraulic power pack is configured to provide pressurized hydraulic fluid for actuating the flight control surface. The local hydraulic power pack comprises a reservoir for the hydraulic fluid and two hydraulic pumps for pressurizing the hydraulic fluid.

A flight control surface with an actuator with an aerodynamic fairing for a swept aircraft wing. The swept aircraft wing includes a movable flight control surface with a hinge line non-perpendicular to the line of flight of the aircraft, and an actuator arm configured to actuate the flight control surface. The actuator arm includes a longitudinal axis substantially aligned with the line of flight, the actuator arm extending at least partially from an outer surface of the aircraft wing, and a fairing arranged on the outer surface of the aircraft wing to at least partially cover the actuator arm. Aligning the actuator arm with the line of flight of the aircraft may allow for an improved fairing to be provided.

Technologies for providing blended wing body aircraft control surfaces are described herein. In some examples, one or more of the control surfaces have angular configurations that reduce the formation of air vortexes when in upward or downward configurations, thereby reducing the drag on the aircraft when the control surfaces are being used.

A spar structure can connect a moveable component to an aircraft. The structure is formed from a single continuous body of material defining a plurality of attachment/actuation brackets and a pair of continuous hinge lines extending through the body.

A lift rotor arrangement (100) for a VTOL aircraft (200). The lift rotor arrangement (100) comprises: a fairing (6) mounted on a wing segment (10); and first and second rotor blades (17, 18) mounted on a first shaft (4) extending vertically from the fairing (6). The first shaft (4) is movable between an extended position in which the first and second rotor blades (17, 18) are vertically spaced above the wing segment (10) and are rotatable to provide vertical lift, and a retracted position in which the first and second rotor blades (17, 18) are rotationally-fixed with the first rotor blade (17) stowed within the wing segment (10). The blades (17, 18) may be rotatable around an axis substantially perpendicular to the axis of the respective first shaft (4) so as to act as ailerons/elevons in the retracted position.

Reactive spoilers for aircraft and associated methods. In one embodiment, a wing of an aircraft includes a leading edge, a trailing edge, and an upper surface and a lower surface between the leading edge and the trailing edge. The wing further includes a reactive spoiler disposed on the upper surface between the leading edge and the trailing edge. The reactive spoiler comprises one or more turbines configured to raise in relation to the upper surface into an airflow passing over the upper surface, and to reduce lift of a wing section behind the turbines. The turbines are configured to convert kinetic energy from the airflow into electrical energy.
