本文采用迭代求解的方法计算弹性机翼的跨音速压强分布。用跨音速小扰动势流的二级近似方法求解气动力;结构变形则采用一维简单梁理论或二维平面结构的柔度影响系数矩阵进行计算。对M6弹性机翼所作的示范性计算表明,计算弹性翼的迭代次数与刚性翼计算相当,弹性变形对冀面气动载荷分布和激波强度均有明显影响。
In this paper, the transonic pressure distribution of elastic wing is calculated by iterative method. The aerodynamic force is solved by the second-order approximate method of transonic small perturbation potential flow. The structural deformation is calculated by using the one-dimensional simple beam theory or the two-dimensional planar structure’s influence matrix of flexibility. The numerical calculation of the M6 elastic wing shows that the calculation of the number of elastic wing iterations is equivalent to that of the rigid wing, and the elastic deformation has a significant effect on the aerodynamic load distribution and shock strength of the wing.
