Abstract: A rotating wing includes a support frame, two connecting rods, two drive systems and a wing frame. The support frame includes a first side frame, a second side frame, a cross frame member, a first guide pin and a second guide pin. The cross frame member is secured to one end of the first and second side frames. A first connecting rod is rotatably retained on the first side frame. A second connecting rod is rotatably retained on the second side frame. The first guide pin extends from the first side frame and the second guide pin extends from the second side frame. The wing frame includes first and second side members. A peripheral groove is formed in an outer surface of the first and second side members to receive the first and second guide pins. First and second drive systems rotate the first and second connecting rods.

Abstract: A propulsion device preferably includes a wing, a pair of sliding rails, an electric motor, an electrical power source, a pair of connecting rod supports and a pair of connecting rods. Each wing includes two lengthwise members, two cross rods, an outer layer and four roller bearings. Each sliding rail includes a lengthwise track formed on an inner surface thereof. Each end of a cross plate is attached to one of the pair of sliding rails. The electric motor is attached to the cross plate. The electrical power source is connected to the electric motor. The electrical power source is preferably secured to one of the pair of sliding rails. One end of connecting rod support is attached to one of the pair of sliding rails.

Abstract: A propulsion device is disclosed which is capable of lifting and/or propelling a person or an aircraft, such as a helicopter or airplane, through the air.
