摘　　要：本文基于压缩性修正,非定常修正,径向流修正,动态失速修正和反流区修正,给出了计算大速度前飞旋翼性能的方法。计算结果表明此方法精度较高,可用于型号设计。An improved roter performance calculation method in high speed flight is devebped, and applied to performance data from wind tunnel tests of MBB. The method is based on lifting line theory, using steady two-dimensional airfoil characteristics. The method includes acompressible flow correction, and unsteady aerodynamics forces correct, a radial flow correction, an empirical dynamic stall correction and a backword flow passage correction, The oorrection demonstrate that the method presented here is accurate and efficient
