Gravitron
Rotor (ride)
https://en.wikipedia.org/wiki/Rotor%20%28ride%29
The Rotor is a large, upright barrel, rotated at 33 revolutions per minute. The rotation of the barrel creates an inward acting centripetal force supplied by the wall's support's force, equivalent to almost 3 g. Once the barrel has attained full speed, the floor is retracted, leaving the riders stuck to the wall of the drum. At the end of the ride cycle, the drum slows down and gravity takes over. The riders slide down the wall slowly. 
Rotor (ride)
The ride is completely enclosed, with 48 padded panels lining the inside wall. Riders lean against these panels, which are angled back. As the ride rotates, centrifugal force is exerted against the pads by the rider, removing the rider from the floor, due to the slant. The ride can reach a maximum speed of 24 rpm in less than 20 seconds, due to the 33 kW 3-phase motor. 
Gravitron
It is a modification of an earlier ride called the Rotor.
