摘要

尾锥推进器配置是实现混合电力推进技术的重要布局。本研究对与机身集成的缩放尾锥电管道风扇进行了数值模拟。研究了风道风扇在边界层摄入情况下的性能变化以及尾锥推进器布局的整体效益。结果表明，与独立风扇相比，尾锥推进器布局的推力增加了 2%。风扇等熵效率降低了 1.03%，但风扇推进效率提高了 15.48%。分析了风扇轴向安装位置对气动性能的影响。结果表明，随着轴向安装位置的增加，推进效率先增加后降低。当轴向安装位置增加到 1.71D 时，推进效率比 1.58D 增加了 0.26%。对攻角的研究表明，在 0° 至 5° 攻角范围内，尾锥推进器布局的气动性能没有明显变化。但当攻角从 10°增加到 15°时，整体推力明显下降了 42.60%。

Aerodynamics coupling study on the tail cone electrical ducted fan integrated with fuselage

The tail cone thruster configuration is an important layout to realize the hybrid electric propulsion technology. This study carries out numerical simulation on the scaling tail-cone electrical ducted fan integrated with fuselage. The performance change of the ducted fan under the boundary layer ingestion and the overall benefit in the tail cone thruster layout are investigated. The results show that compared with the isolated fan, the thrust of the tail cone thruster layout increases by 2%. The fan isentropic efficiency is decreased by 1.03%, but the fan propulsive efficiency is increased by 15.48%. The influence of the axial installation position of the fan on the aerodynamic performance is analyzed. The results show that as the axial installation position increases, the propulsive efficiency first increases and then decreases. When the axial installation position increases to 1.71D, the propulsive efficiency is increased by 0.26% compared with 1.58D. The investigation of angle of attack shows that the aerodynamic performance of the tail cone thruster layout has no obvious change in the range of 0° to 5° angle of attack. However, when the angle of attack increases from 10° to 15°, the overall thrust is decreased significantly by 42.60%.
