전투기 Cockpit용 공기 사이클 냉각 시스템의 개발 시험평가

In this paper, an introduction to the development of Air Cycle Machine designed for environmental control system of a fighter is presented. It has various advantages over a vapor cycle cooling system which inherently needs refrigerant and coolant in terms of simplicity, reliability, weight, maintenance, and eco-friendliness, etc. ACM is a small turbo machine operated on the Reverse Brayton air cycle, where bleed air of an aircraft engine is the source of driving energy and it can be used as cooling and air conditioning through cockpit of aircraft. Development tests are composed of performance tests of major components which are compressor and turbine, operation and performance test of the ACM unit, and qualification test including rotational acceleration test.
