IPC: F03G3/00
Filed: 2003-03-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a stable propulsion device utilizing the centrifugal force by improving a disadvantage of pulsation.  <P>SOLUTION: The propulsion device comprises a rotating means 3 capable of changing the rotational speed, a rotor 1 to be rotated by the rotating means, and a mass 5 fitted to the rotor, and a rotor 2 having a similar mass 6 is synchronously rotated in a reverse direction (the masses are rotated symmetrical to the line 21). The propulsion force is generated in the right direction by controlling the rotational speed so that the rotational speed is higher on the right side of the line 20 and lower on the left side thereof. Since the propulsion force is pulsating, the consistent resultant propulsion force is obtained by combining a plurality of devices of different phase difference and rotational speed of the rotational angle of the rotor.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
