本文应用当地流活塞理论,给出了弹性振动翼面的非定常压力分布以及用模态坐标表示的广义气动力系数表达式。同时提供了配套的当地流参数计算公式和采用样条函数计算广义气动力系数数值积分的表达式。
In this paper, we use the theory of local flow piston to give the unsteady pressure distribution of elastic vibration airfoil and the expression of generalized aerodynamic coefficient with modal coordinates. At the same time, the formula for calculating the local flow parameters and the expression for calculating the numerical integral of the generalized aerodynamic coefficient by using the spline function are provided.
