Book Description
A technique for simulating zero-gravity performance of an astronaut in a pressurized spacesuit by complete water immersion has been developed and investigated. The technique allows the pressure-suited subject to move in six degrees of freedom without the encumbrance of connecting lines or hoses or other supports and further permits performance simulation of long-duration tasks. Experiments were made to demonstrate the relationships between the maneuvers performed by a pressure-suited subject under weightless conditions produced by water-immersion and zero-gravity aircraft flights and those performed under full-gravity conditions. An overall description of the test procedures, pressure suit and modifications, self-contained gas-supply breathing system, and methods for obtaining neutral buoyancy is provided. The tests demonstrated that the simulation technique is useful for premission determination of critical operational characteristics relating to spacecraft and spacesuit design under conditions of zero gravity. In addition, the physical capabilities of man and his ability to perform useful work and maneuvers in a pressurized suit under simulated zero-gravity conditions can be demonstrated by this technique. Test variables included time, suit pressure, and simulation mode. Comparison of the subject?5 motion behavior between the aircraft and water-immersion tests showed that the water-immersion technique is valid where the velocities are low.
