ABSTRACT:
An aircraft1with a spiral inducing assembly2which is capable of inducing the aircraft to travel in a continuous spiralling motion without the aircraft rolling. Two fins6and17are attached to a tube3athat is able to rotate around the encircled part of the fuselage. The fins6, 17are able to rotate in a pivoting manner on the rotatable tube3awith respect to the rotatable tube3a, thereby changing their pitch relative to the longitudinal axis of the rotatable tube3a. Rotation of the rotatable tube is achieved by using an electric motor3bturning a wheel3c. The wheel3cmakes contact with the rotatable tube. When pitched at an angle to the longitudinal axis in unison, both fins6, 17would exert a lateral force on the rotatable tube3a. But as the rotatable tube is pushed sideways, it rotates, and hence the lateral direction of push constantly revolves, causing a spiralling motion of the aircraft when in flight. The rotation of one fin causes the rotation of another fin.
