摘要
以运-7飞机作为参考机型,进行了分布式电推进飞行器的总体设计与性能分析.设计了改型后的分布式电推进飞行器的动力系统,包括螺旋桨参数设计,机翼参数修正,电动机功率计算与选型,螺旋桨气动设计,最终完成混合动力系统的设计.完整地计算了改型后飞行器的各部分质量增减情况并分析其飞行性能,相比参考机型,航程与航时分别增加了 540km与1.2h,增加幅度超过20％,最终进行了分布式电推进飞行器的三维建模与气动特性分析.为分布式电推进飞行器建模、仿真与控制及工程应用提供了理论依据.
Abstract
The Y-7 aircraft was used as the reference model to carry out the overall design and performance analysis of the distributed electric propulsion aircraft.The power system of the distributed electric propulsion aircraft was designed,including design of propeller parameters,correction of wing parameters,calculation of motor power and type selection and aerodynamic design of propeller,and finally the design of hybrid power system was completed.The mass increase and decrease of each part of the distributed electric propulsion aircraft were completely calculated and its flight performance was analyzed.Compared with the reference model,the range and duration increased by 540 km and 1.2 h respectively,up by 20％.Finally,the three-dimensional modeling was established and aerodynamic characteristics of the distributed electric propulsion aircraft were analyzed.The result provides a theoretical basis for the modeling,simulation and control of distributed electric propulsion aircraft and its engineering applications.
