| Abstract: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. |
