Method and apparatus for generating a thrust for use in any environment where thrust is desired as for example for propelling a device whereby the force which moves the device is supplied by the movement inside the device of a mass along a curvilinear path. Since a mass following a curvilinear path necessarily produces a force tending to accelerate the mass toward an instantaneous center of curvature and that force is equal to the mass, expressed in slugs, times the radius, in feet, times the angular velocity squared, in radians/sec., periodic variation of mass, radius or angular velocity of a mass moving in a closed path produces an uncompensated force in a given direction with resultant tendency for movement in that direction. A number of different devices, including devices which utilize the atmosphere being travelled through to interact cyclically with eccentric rotors to produce acceleration and deceleration of the rotor, devices which expel a propulsive fluid after interaction with the rotor to produce cyclic acceleration and deceleration, and devices which produce thrust by cyclic acceleration and deceleration of eccentric rotors through interaction with natural or artifically applied magnetic, electric or thermal gradients, are disclosed.
