Orbital propulsion apparatus which has a rotor drivable by an electric motor and upon which is mounted a plurality of mass members for movement radially of the axis of the rotor, each mass member having a rocket motor mounted thereon which, when fired, moves its associated mass member outwards against a compression spring mounted on the rotor so that at a predetermined angular velocity of rotor the mass members rotate in a common circular orbit, the rockets being controllable so that they can be fired through an arc of predetermined angularity so as to move each mass member radially outwards of its circular orbit to increase the centrifugal force of each mass member across the arc while the electric motor operates to maintain constant angular velocity of the rotor.
