Abstract : The Retrograde Inflation Anti-G Suit (RIAGS) was originally designed and fabricated in the early 1940's by Mr. David Clark and Dr. Earl Wood as The Progressive Arterial Occlusion Anti-g Suit. Testing of this suit on the Mayo Clinic centrifuge revealed that the suit provided more g protection than the fighter pilot of the era needed (+2.9 gz relaxed). This technology was revisited in 1987 by the Armstrong Laboratory and culminated in the development of a new version of the technology using modern methods and materials. The new suit consisted of a retrograde inflating anti-g suit which inflated cephaladward, arterial occlusive cuffs for the arms, and capstan sleeves. These suit combinations were compared to the standard Air Force issue CSU-13B/P anti-g suit. Endurance testing of the current suit involved exposing subjects to a continuous +4.5 to +7 gz Simulated Aerial Combat Maneuver. Results from this study showed the RIAGS with capstan sleeves provided the maximum amount of protection to the subject in terms of endurance (p0.013), followed by RIAGS alone (p0.058), Standard CSU-13B/P and RIAGS with occlusion cuffs (p=0.28). In addition to the protection issue, RIAGS with sleeves also proved to be the most comfortable of all the g suit combinations evaluated
