ROTARY ROCKET

ROTON is a single stage (SSTO) rocket system powered by a number of small liquid-propellant rocket engines attached to the tips of a large diameter rotor blades. Pumping pressure at the rotor tip is supplied by rotational forces of the rotor. At liftoff, the rocket engines are aligned parallel to the ground, with the rotor providing most of the liftoff thrust, while the rocket engines are operating at only a small fraction of their rated thrust. As the vehicle climbs, the engines are aligned with the flight directional axis of the vehicle, and remain in this position until orbital velocity is achieved. Upon re-entry, the rotor may provide both lifting and drag forces, and also permits low velocity, controllable approaches to the landing field. Landing is in a vertical orientation, the same as liftoff. Roton was invented by Bevin McKinney
