Abstract: In the experimental research, a twin-rotor turbojet with aircraft’s inlet was contrasted with the case without aircraft’s inlet, and the state parameter and inlet’s pressure field of the engine were measured. Based on the experimental result, the inlet distortion caused by aircraft’s inlet, the effect of aircraft’s inlet on the performance and platform point of the engine was analyzed as well as the relevant causes. The experimental result has practical significance for correctly using the twin-rotor turbojet.
