Abstract
ObjectiveTo observe the + Gz protection effect of new life support system on the subjects in centrifuge simulated aerial combat maneuver (SACM).
MethodsFour subjects were exposed to SACM centrifuge profile which was composed of five + 4.5 Gz for 10 s, four + 7.0 Gz for 10 s and one + 2.0 Gz for 15 s with an onset rate of 6 G/s. Employing new pilots life support system, the changes of mask pressure, suit pressure, + Gz tolerance and heart rate (HR) were observed during the experiment.
ResultsAll the 4 subjects accomplished the 120 s SACM centrifuge exposure without any unfavorable report or any visual change at each + Gz plateau. There was no incidence of G-LOC. The mask pressure and suit pressure were within the tolerance range.
ConclusionsNew life support system can offer a satisfactory + Gz protection for the SACM with a fast onset rate.
