摘要
发动机舱冷却试验是民用飞机适航取证试飞必须进行的试验项目之一。以某飞机发动机舱冷却系统为研究对象,通过飞行试验研究外界大气温度、电功率提取和引气构型、滑油量、飞行高度、发动机状态、飞机起飞重量、重心等对发动机舱冷却系统性能的影响,形成民用飞机发动机舱冷却试验的临界试验条件,以满足适航条款的适航要求。
Engine nacelle cooling test has become one of demonstration flight tests in civil airplane's airworthiness certification. The influences of outer air temperature, power extraction and bleed configuration, oil quantity, altitude, engine power, weight and C.G on the performance of engine nacelle flight test were studied. Critical flight test conditions were achieved about engine nacelle cooling flight test of civil airplane, which can meet the requirements of CCAR25 airworthiness standards.
