The thrust of the propulsive micro turboprop engine was produced primarily by the propeller. Not only did the nozzle generate residual thrust, but also it could make complex aerodynamic interference with the propeller. In order to explore the variation of thrust characteristics of propulsive micro turboprop engines under interference, the feasibility of the MRF (moving reference frame) method in calculating thrust characteristics of propulsive micro turboprop engines was verified. The CFD (computational fluid dynamics) calculation for the integrated configuration of the propeller, nozzle and nacelle was conducted. The influences of different nozzle pressure ratios, injection angles, propeller speeds, and incoming Mach numbers on the thrust characteristics of the engine during the idling and cruise states were obtained. It was found that, in the ground state, when the injection angle was 0°, the thrust coefficient of the propeller was greater than 0.1, and the maximum difference of the total thrust can reach 36% under the same pressure ratio; when the injection angle was 0°—60°, the propeller thrust coefficient decreased with the pressure ratio, but increased at the injection angle of 90°. In the cruise state, the injection angle and pressure ratio had less influence on the thrust coefficient of the propeller. In contrast, the propeller thrust coefficient decreased with the incoming Mach number and increased with the propeller speed. When the injection angle was 0°, the nozzle’s remaining thrust was maximum, and the total thrust was maximum in these two states, showing good thrust characteristics.
