Evaluation of the Joint Service Mustang Anti-G Suit

Abstract : AFRL/HEPG conducted an initial evaluation of the Joint Service Mustang Anti-G Suit (JSMAGS) produced by Mustang Survival, Inc. Performance of the JSMAGS was compared to that of the CSU-13B/P anti-G suit. Four subjects completed centrifuge trials up to +9 Gz using positive pressure breathing provided by the COMBAT EDGE system in combination with each of the two anti-G suits. The tests were conducted within the limits established by a test plan previously approved by the Brooks Institute Review Board. The constraints of that test plan did not permit a determination of the G-endurance afforded by JSMAGS compared to that of the CSU-13B/P. While the small number of subjects in this quick-look effort did not permit any definitive statistics, these initial test results indicate that JSMAGS provides G-protection that is comparable to that provided by the CSU-13B/P and, as indicated by the heart rate data, may require less physical effort to provide that level of protection. Had the test plan limits permitted a longer SACM exposure, endurance values for JSMAGS may have been better due to a decreased physical effort requirement.
