Abstract: A rotorcraft includes a frame and an engine coupled to the frame. The rotorcraft also includes a rotor hub coupled to the engine and a plurality of rotor blades coupled to the rotor hub. Each rotor blade is configured to be adjusted to a negative pitch angle such that each rotor blade is oriented at a negative angle of attack. The rotation of the plurality of rotor blades at the negative pitch angle generates an updraft that, during a vertical take-off operation, applies an upward force to the rotorcraft to supplement lift generated by the plurality of rotor blades.

Abstract: Airflow-dependent deployable fences for aircraft wings are described. An example apparatus includes a fence of a wing of an aircraft. The fence includes a base that is coupled to the wing and a panel that is movable relative to the base and the wing between a stowed position in which the panel extends along a skin of the wing, and a deployed position in which the panel extends at an upward angle away from the skin. The panel is configured to impede a spanwise airflow along the wing when the panel is in the deployed position. The panel is configured to move from the deployed position to the stowed position in response to an aerodynamic force exerted on the panel.

Abstract: Automated deployable fences for aircraft wings are described. An example apparatus includes a fence, a latching actuator, and a biasing actuator. The fence is coupled to a wing of an aircraft. The fence is movable relative to the wing between a stowed position in which a panel of the fence extends along a skin of the wing, and a deployed position in which the panel extends at an upward angle away from the skin. The panel impedes a spanwise airflow along the wing when the fence is in the deployed position. The latching actuator is movable between a first position in which the latching actuator maintains the fence in the stowed position, and a second position in which the latching actuator releases the fence from the stowed position. The latching actuator moves from the first position to the second position in response to a control signal received at the latching actuator. The biasing actuator moves the fence from the stowed position to the deployed position in response to the latching actuator moving from the first position to the second position.

Abstract: In an example, a power source for an electric propulsion system of an aerial vehicle includes a body having an electrical energy storage device configured to store electrical energy. The power source also includes a plurality of terminals coupled to the electrical energy storage device for supplying the electrical energy from the electrical energy storage device to the electric propulsion system of the aerial vehicle. The power source further includes a plurality of flight control surfaces extending outwardly from the body. The flight control surfaces are actuatable to adjust a flight attitude of the power source. Additionally, the power source includes a flight control system including a processor and configured to actuate the plurality of flight control surfaces to fly the power source to a target location when the power source is jettisoned from the aerial vehicle.

Abstract: In an example, a method of supplying fuel to a fuel tank of a vehicle includes supplying, via a fuel line, fuel to a fuel tank of a vehicle at an initial rate of fuel flow, which causes an electrostatic charge to accumulate on a surface of the fuel in the fuel tank. The method also includes exposing an air medium in the fuel tank to ionizing radiation to increase a level of ionization of an air medium in the fuel tank and increase a rate of dissipation of the electrostatic charge. The method includes determining the level of ionization of the air medium in the fuel tank, and determining an increased rate of fuel flow based on a difference between the determined level of ionization and a baseline level of ionization. The method further includes supplying the fuel to the fuel tank at the increased rate of fuel flow.
