The principal contributions of this dissertation are : 1 . a high fidelity and real - time rotor wake inflow model was built up . based on peters - he finite states wake theory , a new influence coefficient matrix for high speed flight was derived , the modified wake model is better suitable for the flight state with a large wake skew angle 本模型以peters - he有限状态尾迹理论为基础，修正了大尾迹倾斜角时的诱导速度影响系数矩阵，并结合了王氏涡流理论，导出了旋翼诱导速度垂向分量和旋转分量的表达式，可计算平尾、尾桨和垂尾气动中心处诱导速度各分量。
