Title: Dynamic force propulsion unit - has rotor simultaneously spinning as body round support
Inventor: JONES ALEX CHARLES
IPC: F03G3/08
Filed: 1973-08-16
Abstract: The propulsion force is generated by a rotor which simultaneously rotates and spins as a body round a support. The support can be in the form of a radial body carried at one end on a mounting, and carrying the rotor at the other, the rotor axis being in line with the radial body radius. The radius body spins. The radial body spins on the mounting whenever the rotor rotates about its axis, thus compelling the body to swing out through a conical path. This causes a force imparting linear movement to the mounting. Several rotors can be used, and there can be a fork at the free end of the radial body accommodating a gyroscope. The rotors can be those of electric motors, or driven by a jet of fluid striking grooves in their peripheries.
