Abstract
A control device for admitting compressed air into anti-g pilot pants to reduce the effects of forces of acceleration on the pilot. Flight maneuvers with rapid change from negative to positive acceleration shall be made possible by the present invention over a broader range than before. To achieve this, the control device is provided with control means (5-10, 13, 14) for detecting changes in acceleration from negative to positive values, which bring about an additional admission of pressure over a limited period of time with a profile decreasing over time at rates of acceleration change above a predetermined value. This design brings about an additional admission of pressure into the anti-g pilot pants during rapid load changes from negative to positive accelerations, so that an excessively rapid drainage of blood from the dilated blood vessels in the upper half of the body during such transitions can be counteracted by an additional admission of pressure into the anti-g pilot pants over a limited period of time. The control device advantageously operates with pneumatic control branches, which act via a valve control chamber (4) on a main valve (15), which sets the pressure at the controller outlet (12).
