摘要:

本研究建立了适用于不同构型电动垂直起降 (electric vertical take-off and landing, eVTOL)飞行器的简化气动模型,并采用增强延迟分离涡模拟方法,对不同构型eVTOL在起飞、降落、巡航和爬升等典型飞行阶段的气动特性进行了数值仿真。结果表明,起飞阶段复合翼构型的升阻比约为多旋翼构型的1/3,降落阶段两者相近。巡航阶段复合翼构型的升阻比相较于固定翼构型低20.52%,爬升阶段低17.14%。综合比较可知,复合翼构型在起飞阶段逊色于多旋翼构型,降落阶段略优,而在巡航和爬升阶段表现均不及固定翼构型。研究结果为eVTOL的构型方案选择与气动性能优化提供了科学参考与工程依据。

Abstract:

In this study a simplified aerodynamic model applicable to various electric vertical take-off and landing (eVTOL) configurations is established and the improved delayed detached-eddy simulation method is used to numerically simulate the aerodynamic characteristics of different eVTOL configurations during typical flight phases, including take-off, landing, cruise, and climb. The results show that the lift-to-drag ratio of the lift-and-cruise configuration during take-off is approximately one-third that of the multi-rotor configuration, while the two are comparable during landing. During the cruise phase, the lift-to-drag ratio of the lift-and-cruise configuration is 20.52% lower than that of the fixed-wing configuration, and 17.14% lower during the climb phase. Overall, the lift-and-cruise configuration is inferior to the multi-rotor configuration during take-off, slightly outperforms it during landing, and falls short of the fixed-wing configuration in both cruise and climb phases. The findings provide scientific guidance and an engineering basis for eVTOL configuration selection and aerodynamic performance optimization.
