Abstract
An anti-G system is used to combat the push-pull effect experienced by airmen during and after a transition from a period of low or negative G force levels to high G force levels. The anti-G system includes an anti-G controller configured to receive signals indicative of airman acceleration and anti-G garment pressure. The anti-G controller is coupled to a valve controller controlling fill and vent valves controlling the pressure level in the anti-G garment. As the anti-G controller receives acceleration signals indicating G force levels over time, the controller calculates whether the anti-G garment pressure should be increased or decreased and transmits signals to the valve controller to increase or decrease anti-G garment pressure. Increasing the anti-G garment pressure compensates for the airman's loss of tolerance to high G levels immediately after exposure to a period of low or negative G levels.
