Patent ID: 7165742

Claim:
An aircraft comprising a spiral inducing assembly, which said spiral inducing assembly is capable of forcing the aircraft to travel in a spiralling motion during flight or the aircraft and which spiral inducing assembly comprises a tube, which tube encircles part of the aircraft and is able to rotate relative to the encircled part of the aircraft, with a plurality of fins connected to the tube, which fins are connected to the tube such that the fins can be rotated in a pivoting mariner relative to the tube, and such that the fins can be rotated in the said pivoting manner in the sane direction relative to the tube, and which spiral inducing assembly comprises a fin rotating mechanism by which fin rotating mechanism the fins can be rotated in the said pivoting manner in the same direction as each other relative to the tube and such that rotation of one fin in a pivoting manner relative to the tube causes rotation of another fin relative to the tube in the same direction as a direction of rotation of the said one fin relative to the tube, and which said fins are such that rotation of the fins in the said same direction relative to the tube during flight of the aircraft can enable one of the fins to exert a magnitude of force on the tube that is greater than a magnitude of force that another of the fins can exert on the tube.
