Comparative Centrifuge Evaluation of the Air Force Advanced Technology Anti-G Suit (ATAGS) and the Navy Enhanced Anti-G Lower Ensemble (EAGLE)
Abstract
The centrifuge evaluation of the ATAGS and EAGLE was undertaken to determine which extended coverage anti-G suit would enter engineering and manufacturing development for joint service use. Eight male centrifuge subjects were used, wearing either an ATAGS, with or without pressure socks, or an EAGLE. Pressure breathing during G (COMBAT EDGE) was used with all three combinations. The combinations were randomized to eliminate any order effect. The arms of all subjects were wrapped from the wrist to the axilla with 3 in. wide elastic bandage to reduce the possibility that subjects might stop the +Gz exposure for arm pain rather than for fatigue or light loss. GOR, ROR, and 5-9 SACM +Gz profiles were used to compare the suits. Although not significantly different, the average number of 9G plateaus completed (endurance) for the ATAGS with socks, the ATAGS without socks and the EAGLE were 8.0, 7.8, and 6.5, respectively. Subject HR while wearing the ATAGS with pressure socks was significantly (p=.03)lower than HR while wearing the EAGLE during the 5G plateaus of the 5-9 +Gz SACM. The perceived effort involved in the straining maneuver during the 5-9 SACM with the EAGLE was consistently, but not significantly, greater across the 9G plateaus compared to the ATAGS with pressure socks. However, there was a significant (p=.032) suit/time interaction between the ATAGS with pressure socks and the EAGLE. There was no significant difference in subject HR or +Gz tolerance between the three G-suit combinations during the GOR or ROR +Gz exposures. +Gz, +Gz Tolerance, Anti-G Suit evaluation, Extended coverage, Anti-G Suit.
