扁平融合式飞机整体式进/排气试验的推/阻校准方法

在研究嵌入式动力装置的进/排气效应对扁平融合式飞机气动特性的影响时，发展了一种整体式进/排气模拟试验方法及推/阻校准方法。采用与飞机模型融为一体的内置式引射器同时模拟飞机的进气效应和排气效应，模型气动载荷与引射器工作时的作用力由天平同时测量获得；把模型推进系统部分分离出来，在TPS校准箱中进行推/阻校准，建立模型气动载荷与推/阻力之间的剥离方法，获得真实的进/排气效应影响试验数据。用典型的背负式进气道扁平融合式飞机模型进行了推/阻校准试验和进/排气影响风洞验证试验，验证了该方法的可行性。

Thrust/drag calibrations for integral inlet and jet testing on a aircraft with blended wing/body

When researching on the influence of the inlet and jet exhaust plume of the embedded propulsion system on the aerodynamic characteristics of a blended wing/body aircraft, a calibration method of thrust and drag for the integral inlet and jet simulation test is developed. The embedded ejector integrated with the aircraft model is employed to simulate the inlet and jet effects simultaneously. The total value of the aerodynamic load on the aircraft model and the thrust of the working ejector are measured by the balance. With the TPS calibration tank, the thrust and drag of the propulsion system can be calibrated, the decoupling of the aerodynamic load on the aircraft model with the thrust and drag of the propulsion system can be efficaciously realized, and the reliability data of inlet and jet effects can be obtained. The thrust/drag calibration method is verified by the inlet and jet simultaneously testing with black-embedded inlets of a blended wing/body aircraft.
