An artist’s concept for a full scale Slingatron space launcher about 200-300 meters in diameter. The spiral track is mounted on support pylons which contain drive motors and counterweight flywheels. Payload assemblies are prepared for launch nearby.
In preparation for payload launch, the Slingatron is gradually gyrated up to approximately 40-60 cycles per second. Once the Slingatron track is cycling at launch speed, the payload module is released into the entrance of the track near the center of the rapidly gyrating spiral track. Once within the track, the payload module accelerates and quickly becomes phase-locked with the gyrating action of the entire platform as a result of the tremendous acceleration. The strong centrifugal force causes the payload module to continue accelerating throughout the spiral track. From the perspective of the payload module, it appears to be constantly sliding down a steep incline under a very high “gravitational force”, which is actually due to the centripetal acceleration. At high speed, the payload slides on a “plasma bearing” film that forms between the bottom of the payload and the surface of the steel track. This plasma bearing provides a very low coefficient of friction cushion which allows the rapid acceleration. When the payload reaches its launch velocity of about 7 km/sec in the last spiral turn, it then launches through a track angled up a hill or other structure to direct it into space.
