Technical Evaluation of the UH-60Q: Medical Oxygen System

摘要

The UH-600 prototype MEDEVAC Black Hawk is configured to provide day/night,adverse weather, emergency movement of patients. The objective of this report is to describe the results of performance tests on the medical oxygen system installed on the prototype aircraft. The medical oxygen system in the aircraft consists of a molecular sieve oxygen generating system (MSOGS) and support equipment. The MSOGS uses bleed air to produce high concentration oxygen. The MSOGS in the prototype aircraft is capable of producing 15 to 20 lpm of 94% oxygen and storing 163 1 of oxygen in the backup oxygen supply (BOS). Lower bleed air pressures in ground tests may account for some decrement in performance of the MSOGS when compared to laboratory testing. Inflight testing is required. The support equipment, including oxygen concentration analyzer, BOS pressure monitor, and oxygen flowmeter do not function properly. The regulated oxygen pressure to too low to allow proper operation of the oxygen flow selectors. The oxygen analyzer is redundant and can be eliminated; the flowmeter could be eliminated if the oxygen flow selectors function properly.
