VERTICAL TAKEOFF AND LANDING AIRCRAFT WITH PASSIVE WING TILT

The present disclosure pertains to self-piloted, electric vertical takeoff and landing (VTOL) aircraft that are safe, low-noise, and cost-effective to operate for cargo-carrying and passenger-carrying applications over relatively long ranges. A VTOL aircraft has at least one wing that is rotatable relative to a fuselage of the VTOL aircraft for transitioning the VTOL aircraft between a hover configuration and a forward-flight configuration. Rotation of the wing may be passively controlled using aerodynamic forces, thereby obviating the need of using an actuator for actively controlling the rotation.

Thrust allocation for aerial vehicle
10513341 · 2019-12-24 · ·

A technique for controlling vertical propulsion units of an aerial vehicle includes determining whether an initial thrust command output vector results in a thrust command clipping of one of the vertical propulsion units. The vertical propulsion units are physically organized into propulsion rings including an inner ring and an outer ring. Torque associated with the initial thrust command output vector is transferred from each the vertical propulsion units in the outer ring to the vertical propulsion units in the inner ring when the thrust command clipping of one of the vertical propulsion units in the outer ring occurs. A revised thrust command output vector is determined after transferring the torque. The vertical propulsion units are driven according to the revised thrust command output vector.
