C2A1 and Low Profile Air Filter Pack Flow Characteristics with Navy Combat Edge
Abstract
One of the objectives of the Joint Services Aircrew Mask program was to add chemical, biological protection to an aircrew's breathing system such as the Navy Combat Edge (NCE). The purpose of this test was to compare and evaluate the compatibility of the C2A 1 and Low Profile Air Filter Pack (LPAFP) canister with the NCE system. Areas of specific concern were the pressure drops associated with the canisters. The canister test was split into four phases including an endurance test, a steady flow test, a dynamic flow performance test, and a system lag time test. The endurance test was designed to monitor the canisters for charcoal degradation and system variation over an 8-hr period with an average breathing rate. The steady flow test gives a close look at the performance of the system at peak flow rates. The data also provided baseline figures for the dynamic flow performance test. The dynamic flow performance test recorded the system's performance with realistic breathing profiles simulating conditions of high demand with G's. The system lag time test was performed to analyze the response time of NCE with the added restriction of the canisters.
