摘要
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。
By using the local flow piston theory, the pressure distribution of unsteady flow for wing with elastic vibration, and the formulas about the general aerodynamic coefficients expressed by modal coordinates are obtained. The corresponding formulae to calculate the local airflow parameters and the numerical integration formulae about general aerodynamic coefficient calculated by spline functions are provided.
