Abstract

A propulsion engine and its use in a vehicle and method for space propulsion of a vehicle in a gravitational field for orbital altitude control or travel in deep space. The propulsion engine of the vehicle employs non-ejectable propellant masses that are accelerated cyclically in a selected average vectorial direction between two random and distinctive points following any random path with a mean central point, thereby generating and amplifying local gravity assist. The acceleration of the non-ejectable propellant masses causes the propulsion engine to accelerate the vehicle away from the source of the gravitational field to a tangential velocity that matches or exceeds the stable tangential velocity to maintain or raise the vehicle to a second stable orbital altitude, or continuously and locally generates gravity assist boost moving through the cosmic gravitational field lines in deep space.
