Roton Rotary Rocket SSTO with Helicopter Landing

Rotary Rocket Company was a rocketry company that developed the Roton concept in the late 1990s as a fully reusable single-stage-to-orbit (SSTO) crewed spacecraft with a rotating annular aerospike engine to pump fuel and oxidizer to the rim by the rotation and a helicopter rotor on top used for landing.
The design was initially conceived by Bevin McKinney, who shared it with Gary Hudson.
