摘要
我国高原机场数量较多,而高原机场条件会对动力装置以及飞机的性能产生影响。因此,发动机在高原机场进行飞行试验是必不可少的,该试验对改进飞机的起飞和着陆性能有着重要的影响。某型民用涡扇发动机的高原试验中,对引气构型、发动机状态(特指冷态和热态)以及起飞方式不同组合确定典型试验点,对典型试验点的风扇转速(N1)和排气温度(EGT)进行统计并比较,基于试验数据和相似换算参数的比对,得到该型发动机不同状态、不同引气构型及不同起飞方式对性能的影响。该结论具有普遍性,有一定的工程参考意义。
There are more numbers of plateau airports in our country,and the conditions of plateau airport will affect the performance of power plant and aircraft,so flight test for aircraft engine in the plateau airport is necessary,and the test has an important influence on the performance of aircraft takeoff and landing.In the flight test for a certain type of civil turbofan engine in plateau airport,according to the typical test points combined by different bleed configurations,engine conditions（especially cold engine and warm engine）and takeoff ways,the fan speed（N1）and EGT（exhaust gas temperature）of these test points are counted and compared.Based on the comparisonbetween the experimental data and corrected parameters,the influences of different status,different bleed configurations and different takeoff way on the performance of the engine are obtained.The result is universal and meaningful in engineering.
