Human centrifuge. TsF-18 centrifuge used to train cosmonauts at Star City (Zvezdny Gorodok), Russia, for manned missions. The centrifuge simulates the acceleration felt by cosmonauts in spaceflight. Cosmonauts are placed in the capsule at the end of the centrifuge's arm and spun in a horizontal plane at high speed. The cosmonaut feels the centripetal acceleration needed to keep him or her moving in a circle.
