摘要: 描述了数值计算有升力旋翼的跨声速流场过程。采用有限体积法在桨叶固接坐标系直接求解三维欧拉方程。没有附加任何尾迹模型,给出了粗细网格所对应的浆叶表面压力系数和沿展向升力系数,计算结果与实验数据吻合较好。

关键词: 旋翼, 欧拉方程, 有限体积法, 压力系数

Abstract: A new method is presented for calculating the quasi steady transonic flow over a lifting rotor blade in hover by using Euler equations. The approach is to solve the Euler equations in a rotor fixed frame of reference using a finite volume method. The results are verified by comparison with wind tunnel data. In cases considered, good agreement is found with available experimental data.

Key words: rotor, euler equations, finite volume, pressure coefficient
