DEVELOPMENT OF A GRADED PNEUMATIC WHOLE BODY G SUIT

THE OBJECT IS TO DEMONSTRATE AN APPROACH FOR PNEUMATIC WHOLE-BODY GRADED COUNTER PRESSURE ANTI-G PROTECTION OF A PILOT. THIS EFFORT WOULD BE TO MATCH PNEUMATICALLY THE COUNTER PRESSURE GRADIENT PRODUCED BY A FULL-BODY IMMERSION SUIT. THIS APPROACH SHOULD BE CAPABLE OF PROVIDING LEVELS OF CIRCULATORY SUPPORT AND G PROTECTION APPROACHING THAT OF FULL-BODY IMMERSION SUITS. BECAUSE THIS APPROACH IS PNEUMATIC IT WILL HAVE ADVANTAGES OF BEING LIGHT, EASY TO MOVE IN AND BE COMPARATIVELY EASY TO INTEGRATE INTO AIRCRAFT. THIS ANTI-G SUIT WOULD IDEALLY BE DRIVEN BY A SINGLE PNEUMATIC SOURCE (ANTI-G VALVE). THE GRADED COUNTER PRESSURE WOULD BE ACHIEVED BY USING PNEUMATIC SYSTEMS WITH DIFFERENT PRESSURE TRANSFER EFFICIENCIES. THE PROPOSED GARMENT WOULD TAKE INTO CONSIDERATION THE PILOT COMFORT. BY UTILIZING MATERIALS IN THE PNEUMATIC BLADDERS THAT WOULD ALLOW SOME COOLING THROUGH SWEATING, THERMAL LOADING COULD BE PREVENTED.
