飞机带动力模型试验前准备与校准研究

带有高涵道比发动机的民用飞机无论是在高速还是低速飞行时,发动机进、排气对气动特性的影响都不可忽视,尤其是在低速增升构型时进排气的影响更为重要。为了研究发动机动力影响对飞机气动特性的影响,在一个飞机半模模型的发房内安装了TPS发动机模拟器,通过构型变化和运行参数调节来获得低速状态下带动力的影响量。为了获取可靠的数据,试验前需要对TPS进行必要的调试与校准,本文对这些内容进行了详细的阐述。

Research on Preparation and Adjustment of Aircraft Model with TPS

No matter high speed flight or low speed flight,blowing and suction effect on aircraft engine cannot be ignored,especially the high-lift configuration at low speed flight. To investigate the blowing and suction effect on aircraft engine,a TPS was mounted inside the nacelle of a half model of aircraft;influence quantity of TPS at low speed was obtained by changing the model configuration and adjusting running parameter. In order to get the reliable data,it is necessary to test and adjust the TPS unit before wind tunnel test. This paper discusses this process clearly.
