摘　　要：基于分布式电推进飞机研究方向大多仍在总体、气动、动力系统优化设计方面的现状,针对某项目分布式电推进飞机方案,开展了分布式电推进飞机动力学特性分析和评估方面的研究。通过基于涡格法和激励盘模型的快速气动评估计算与分析,分别对分布式增升系统开/关两种构型开展基本气动特性分析以及操稳特性评估对比。结果表明,分布式增升系统的开启能够提升升力特性,但分布式增升系统开/关也将改变飞机稳定特性;最终通过调整重心位置能够使飞机拥有较好的稳定特性和理想的配平操纵舵偏。Based on the fact that the research direction of distributed electric propulsion aircraft was mostly focused on the overall,aerodynamic and power system optimization design,this paper has carried out research on the analysis and evaluation of the dynamic characteristics for a distributed electric propulsion aircraft.Through the rapid aerodynamic calculation and evaluation analysis based on the vortex lattice method and the excitation disk model,the basic aerodynamic characteristics analysis and the stability evaluation comparison were carried out for the two configurations of the distributed high-lift system ON/OFF.The analysis results shows that the opening of the distributed high-lift system can improve the lift characteristics of the aircraft,but the ON/OFF of this system will also change the stability characteristics of the aircraft.Finally,by adjusting the position of the center of gravity,the aircraft has a better stability characteristics and ideal trim control rudder deflection.
