Abstract
Abstract Unidirectional thrust and consequent unidirectional motion are achieved by rotating thrust producing units in a circular orbit. The thrust producing units involve weights or masses which are caused to accelerate in the direction of the orbital travel during all or a portion of the one-half of the orbital travel which is away from the direction of the desired thrust. The reaction to this acceleration occurs and manifests itself at an orbital location-i.e., away from the axis of rotation-and provides the unidirectional thrust. During the one-half of the orbital travel which is toward the direction of the desired thrust there either is no such acceleration or the reaction to such acceleration is directly transferred to the axis of rotation, and consequently in either case no reaction is manifested at an orbital location. Hence, there is no thrust in the direction opposite that desired.
