Description
VERTICAL TAKE-OFF AIRCRAFT This invention relates to the vertical take-off field of aviation.
There are many helipcopters and gyrocopters in existence today. However, helicopters rely on variable pitch rotor blades to maintain control and provide vertical lift, while aircraft commonly referred to as gyrocopters are pushed in a forward direction on take-off due to the backward thrust of air caused by the propeller located to the rear of ooo: the engine assembly.
.e The present invention overcomes the need for varying the pitch of rotor blades while at the same time i: allowing vertical lift on take-off and directional 15 control by providing a vertical take-off aircraft using an assembly of blades and a rotor mechanism at the top of the craft, which rotor blade assembly is connected to the main body of the craft in such a way that the said rotor blade assembly can be tilted as a whole unit in various directions and angles and thus allow changes in horizontal directional travel of the craft by tilting the upper rotor blade assembly in the chosen direction of travel, without the need to change blade pitch angle. Vertical lift is obtained by the rotation of the upper rotor blade assembly thereby forcing air in a downward direction by way of the angle of pitch of the blades. Rotation of the upper rotor blade assembly is achieved using an engine assembly located between the main body of the craft and the upper rotor blade assembly which engine assembly is attached to the main body of the craft in such a way that the *engine assembly and the upper rotor blade assembly can be titled together as a unity relative to the main body of the craft and such that the rate of revolution of the upper rotor blade assembly can be controlled. During flight, rotational stability of the main body of the craft is maintained by means of an additional engine assembly attached to the main body of the aircraft which 20 rotates an assembly of rotor blades at a controlled rate of revolution pushing air 4 primarily in a horizontal direction to counter the rotational force exerted on the the main body of the craft by the rotation of the upper rotor blade assembly.
