Breathing Resistance Properties of the Combat Ace (TLSS Phase IV B & C) Chemical Defense Respirator

摘要

Positive Pressure Breathing for G (PBG), under the program name COMBAT EDGE, is used to provide acceleration protection in high performance fighters. This work compares its breathing resistance to a chemically hardened version of the system (COMBAT ACE) and the standard Aircrew Bye-Repository Protection (AERP) system. COMBAT EDGE was seen to meet ASCC (Air Standardization Coordinating Committee) Standard 61/22A over most of its performance range, but its integration into COMBAT ACE resulted in a loss of ASCC compliance. In spite of this, test-subject questionnaires revealed no reports of air hunger or reduced acceleration protection, and its breathing resistance was appreciably less than the standard AERP. This suggests that the COMBAT EDGE breathing system can be chemically hardened into COMBAT ACE without perceptible effect on its protective capability.
