  • Variable gravity simulation system and process
    Patent number: 5718587
    Abstract: A variable gravity simulator for giving a test subject, such as an astronaut, six degree freedom of movement in a variety of effective gravities by using a nearly uniform gas/liquid mixture as an immersion medium. This technique retains most of the benefits of conventional methods of varying effective gravity through immersion in a liquid yet greatly reduces the most serious drawback by reducing the resistance to all movement due to the immersion liquid's viscosity.
