[+Gz protection of the on board oxygen generating system (OBOGS) and anti-G equipment].

Objective To investigate the +Gz protection of the on board oxygen generating system (OBOGS) and anti G equipment. Method Physical and physiological tests of the OBOGS and anti G equipment were accomplished using human centrifuge. +Gz tolerance of ten male subjects with or without the anti G suit, pressure breathing for G (PBG) and OBOGS were determined. Result The performance of the OBOGS and anti G equipment fulfilled the requirements. The +Gz protections of the anti G suit, PBG, and anti G system were 2.08 G, 1.92 G, and 3.92 G, respectively. Conclusion The +Gz protection of the OBOGS and anti G equipment satisfy the performance requirements of high performance aircraft.
