这里提供一个计算旋翼在挥舞平面内的气动载荷的方法,可同时计算刚性桨叶和弹性桨叶的载荷和动应力。 原始数学模型采用南京肮空学院王适存教授的空气动力模型,基本假设均与文献[3]相同,在本文中不再赘述。 本方案采用逼近法求解,即用曲线拟合法来计算刚性桨叶的载荷,用迭代法计算弹 Here’s a way to calculate the aerodynamic loading of a rotor in a waving plane that simultaneously calculates the loads and the dynamic stresses on the rigid blades and the flexible blades. The original mathematical model uses the aerodynamic model of Professor Wang Shi-cun from Nanjing Bad College. The basic assumptions are the same as those in [3] and will not be repeated in this paper. This program uses the approximation method to solve, that is, using curve fitting method to calculate the rigid blade load, iterative method to calculate the bomb
