Breathing and acceleration protection apparatus for aircraft crew members

摘要

A breathing and acceleration protection apparatus for the pilot of a fighter aircraft includes a source of pressurized respiratory gas (typically a liquid oxygen converter) and an anti-g regulator valve means fed by the source and connected to inflatable trouser pockets of a g-suit carried by the pilot. A demand regulator delivers respiratory gas to the pilot. The anti-g regulator valve includes an inertia body movable responsive to acceleration along a predetermined direction for increasing the pressure in the pockets and when an amount of acceleration in excess of 2 g is sensed. Additional means responsive to the aircraft altitude establish a static pressure in the pockets at a value which increases with altitude in the absence of acceleration.
