A METHOD GENERATLNG NUTATION FORCE AND INTERNAL PROPULSION SYSTEM OF CLOSED SYSTEM USING A NUTATION FORCE

摘要

PURPOSE: A method of generating longitudinal force inside a closed system and an inner propulsion system of the closed system using the longitudinal force are provided to freely move a closed system by using longitudinal force and to move the closed system under water or vacuum. CONSTITUTION: A method of generating longitudinal force inside a closed system comprises steps of locating a core mass(18) with a predetermined distance from the gyrating mass center at space coordinates; inclining the core mass at a predetermined angle, centering around a vertical shaft(12); and rotating the core mass at a predetermined angular velocity, centering around the vertical shaft. The longitudinal force generated to the inside of the closed system is used as inner propulsive force of an actuator and therefore, the closed system can be moved freely under gravity field and also free movement of the closed system under vacuum is possible.
