Effect of Muscular Straining on G-Protection during Assisted Pressure Breathing.

摘要

The purpose was to study the effect of anti-G straining maneuvers on the less than protective properties afforded by the anti-G ensemble used in the FAS 39 Gripen aircraft (AGE-39). Ten subjects were studied in a centrifuge using: (1) the AGE-39 in combination with full anti-G straining maneuvers (AGSM) throughout each high-G exposure (Full Maneuver; FM) and (2) the AGE-39 in combination with AGSM during the initial part of each high-G exposure (Reduced Maneuver; RM). G-intensity tolerance was established during exposures to Rapid Onset Rate (ROR) profiles with G-plateau levels ranging from 6.5 to 9.0G. G-endurance was studied during Simulated Aerial Combat Maneuvers (SACM) consisting of ten cycles of 5.5 to 7.5 G.
