Abstract
A gravity protective system for pilots including a pressurized suit and a control system therefor for regulating the pressure in the suit in response to variations in acceleration along the thoracic axis of the pilot. Signals indicative of acceleration along the vertical axis of the aircraft and cosine function of the tilt angle of the pilot's seat are combined with a derivative function of their product to produce a control signal for regulating the air pressure within the suit. A threshold control limits regulation to acceleration above a predetermined level, and a feedback circuit from the suit ensures rapid response without oscillation.
