Abstract:
A technique for simulating the zero-gravity-environment inside and outside space vehicles is described. A servo-driven/computer-controlled simulator provides motion to the astronaut equivalent to that experienced in a zero-g environment. The instrumentation systems required to generate the necessary input data to the analog computer, programmed with the EVA/IVA dynamic equations, are discussed. The instrumentation consists of a load cell array to sense the forces and moments applied to the spacecraft by the astronaut during orbital activity and a unique limb motion sensor that continuously measures the astronaut's limb positions. The design considerations for the simulator are presented, and various space missions conducted on the simulator, with primary emphasis on EVA, are discussed
