考虑气动弹性变形影响的跨声速机翼设计方法研究

An Aerodynamic and Aeroelastic Integrated DesignMethod for Transonic Wings

根据气动—结构一体化的设计思想，发展了一种考虑气动弹性变形影响的跨声速机翼 Ｃ Ｆ Ｄ 设计方法。设计实践表明，采用适当的结构弹性模型，方法可以在计及机翼静弹性变形影响的情况下设计出压力分布收敛于指定目标的新机翼，因此在跨声速机翼型架外形的设计和吹风模型的真实外形设计中具有良好的实用价值。

In this study,a CFD design method of transonic wings is developed,which is taking account of aeroelastic effects and based on the integrated design strategy of aerodynamic and structure elasticity.It can be stated clearly from the design practice that,by means of using the proper structure elastic model,the method of this paper can design the new wing,whose wing pressure is converged to the target wing pressure and taking into account of aeroelastic effects,and the method is of better practical value in designing the assembly fixture contours and the machining configurations of wind tunnel test models of transonic wings.
