| 中文摘要: |
| 为了确定发动机地面装机条件下的进气畸变大小，对1 种全尺寸进气道与发动机地面台架开展进发联合试验研究。试
验速度条件为飞机静止状态，对应飞机迎角为0毅，马赫数为0。参试进气道为2 元外压式超声速进气道，参试发动机为大推力双转
子带加力涡轮风扇发动机。采用地面台架联合试车的方法，获得了不同进气道条件下的进发匹配特性数据，包括在发动机不同工作
转速下进气道出口流场的稳态总压特性、动态畸变特性等参数，并与进气道缩比模型风洞试验结果进行了对比分析。结果表明：全
尺寸进气道的出口畸变随发动机空气流量增加而增大，与风洞试验结果一致，但防护网对于畸变的影响效果相反。 |

| In order to determine the distortion under the engine installed conditions, a combination test were studied on a full scale
inlet and an engine ground testbed. The speed condition of the test was simulated at the aircraft stationary state, the corresponding angle of
attack was 0毅and mach was 0. The tested inlet was a two-dimensional external-compression supersonic inlet, the tested engine was a large
thrust double spod turbofan with afterburer. Using the ground testbed combined test method袁the test got the inlet characteristic parameters
including steady-state pressure distortion, time-variant distortion at the Aerodynamic Interface Plane (AIP) in various engine rotating speed,
and test results were compared with the wind-tunnel. Results show that the distortion of full scale inlet increases with the engine air flow
increases, which is consistent with the results of scale model test in the wind-tunnel, but the effect of the protective net on the distortion is
opposite against the wind-tunnel. |
