【摘要】 描述了三维Ｅｕｌｅｒ方程数值模拟旋翼悬停流场的过程。欧拉方程的求解采用了网格中心有限体积法，五步Ｒｕｎｇｅ－Ｋｕｔｔａ时间推进格式。在没有建立尾迹模型的前提下，计算了两叶旋翼在亚、跨声速时的压强分布，并将计算结果与国外实验数据作了对比，二者吻合程度良好。更多还原

【Abstract】 A numerical procedure is presented for calculating the flowfield over a lifting and nonlifting rotor in hover.The approach is to solve the inviscid compressible Euler equations in a rotor fixed frame of refrence using a finite volume method and Runge Kutta scheme.Without any wake model,the pressure distributions are presented for two bladed rotor,the theoretical results show good agreement with experiment data.更多还原
