Abstract: An anti-G suit simulation system and especially pertains to an arrangement or system for simulating realistic acceleration conditions which are normally encountered during strenuous maneuvers carried out by pilots operating high-performance aircraft, such as jet fighter aircraft. More particularly, there is disclosed an anti-G simulation system wherein aircraft simulator pilots are exposed to physical conditions which rapidly and faithfully simulate and compensate for changes in high-intensity accelerations and gravitational effects or so-called G-conditions which are ordinarily encountered by the pilots of high-performance aircraft during the execution of aircraft maneuvers.
