| 摘 要： | 采用自由涡系理论 ,用时间历程法逐步迭代计算直升机桨叶的环量和涡迹坐标。每一方位反复迭代直至尾迹稳定 ,从而得到其诱导下洗。最后以某直升机为例 ,将求出的诱导下洗用于桨叶气动载荷计算。计算出的气动载荷与实验结果相吻合

| Abstract: | Coordinate of circulation and wake of helicopter blades are iterated step by step with the method of time history in the theory of free vortices. Each azimuth is re iterated until its wake is stable and its induced down wash flow is obtained. The down wash flow calculated in an example of a certain helicopter can be used for aerodynamic load calculation of blades. The calculated results coincide well with the test data. |
