ABSTRACT:
A weightlessness simulator (10) has a chamber (12) and a suit (56) in the chamber (12). O-rings (26) and valves (30, 38, 42 and 66) hermetically seal the chamber (12). A vacuum pump (32) connected to the chamber (12) establishes a pressure in the chamber (12) less than atmospheric pressure. A water supply tank (34) and water supply line (38) supply a body of water (44) to the chamber (12) as a result of partial vacuum created in the chamber (12). In use, an astronaut enters the pressure suit (56) through port (60), which remains open to ambient atmosphere, thus supplying air to the astronaut during use. The pressure less than atmospheric pressure in the chamber (12) is chosen so that the pressure differential from the inside to the outside of the suit (56) corresponds to the pressure differential with the suit (56) in outer space.
