  • Patent number: 10752351
    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.
