Abstract

An electrically powered vertical takeoff and landing aircraft (EVTOL) includes a payload module, a plurality of electrical power sources, a wing, and a plurality of electric thrust generators. The wing is pivotally attached to the payload module and is configured to pivot about a pivot axis, relative to the payload module, to transition between vertical flight and horizontal flight. The electric thrust generators are operatively attached to the wing, where each one is operatively connected to a different electrical power source. The electric thrust generators operate to provide thrust to the aircraft in response to receiving electric power from the electrical power sources. The electric thrust generators pivot, with the wing, about the pivot axis, relative to the payload.

Abstract

An electric tail-sitter aircraft configured to transport passengers and/or cargo between locations. The aircraft includes a flight module, a ground module and a payload module. The flight module is a wing that can rotate with respect to the rest of the aircraft, from vertical to horizontal and vice versa. A plurality of electrically driven propellers are attached to the wing, providing vector thrusting (through the rotation of the wing) and differential thrusting to control the different phases of the flight (vertical take-off and landing, horizontal, transition between the previous two). The payload module is an interchangeable component that can be a cabin for passenger transportation or a cargo container. It can actively shift its position in the aircraft in order to control the center of gravity position. The ground module may include wheels, a transmission, suspension, and carry the payload module. It is connected to the flight module through an L-shaped hinge, where the wing rotates to a plane behind the hinging point, in order to have the center of gravity adjusted as to be located on the hinging axis.

Abstract

An unmanned air vehicle is provided. The unmanned air vehicle includes a frame having a center portion connecting two substantially parallel transversely spaced apart ele-wings. The ele-wings may store batteries and rotate along a forward axis to provide lift during a transition from vertical flight to linear flight. The landing gear may be connected to the ele-wings and configured to change pitch of the ele-wing to ensure stable flight during flight mode transition. A plurality of propellers, each having propeller drive motors, are attached to the frame and able to rotate from parallel position, relative to the center portion, for vertical flight to a perpendicular position, relative to the center portion, for linear flight. The propeller drives rotate on its axis and may be configured to propel the vehicle in a ground and flight mode.
