Disclosed is a device for producing a unidirectional force which may be used to propel a vehicle or other body in one direction or to serve in other applications requiring such a force. The device uses a centrifugal force generator which repetitively provides alternately occurring prolonged centrifugal forces of opposite direction along a line fixed relative to the generator. As these forces are produced the generator is turned relative to a supporting carriage so that each time such a force occurs it has a generally forward direction relative to the carriage. Two or more centrifugal force generators may be mounted on a single carriage and operated in synchronism and in proper phase relationship to one another to produce a forwardly directed force of relatively steady magnitude and/or to cancel force components directed perpendicular to the forward direction.
