一种考虑静气动弹性影响的机翼型架外形设计方法

在机翼静气动弹性分析的基础上,结合Takanashi余量修正方法对三维机翼进行气动外形反设计,以确定机翼的型架外形。其中静气动弹性分析采用耦合计算流体力学和计算结构动力学(CFD/CSD)方法进行数值模拟。气动力采用N-S方程的有限体积求解技术,结构响应则采用有限元数值求解技术。以某客机方案机翼作为算例,设计结果表明本文所建立的机翼型架外形设计方法是可行的,具有一定的工程应用价值。

A design of wing shape of considering influence of static aeroelastic

Combining the wing static aeroelastic analysis and Takanashi residual-correction inverse design method of wings,a method which considering elastic deformation influence is developed to design the aerodynamic configuration of three-dimensional aircraft wing.The method that analyze static aeroelastic is a numerical simulation technology which combined Computational Fluid Dynamics(CFD) method with Computational Structure Dynamic(CSD).Aerodynamic is computed by N-S equations finite volume technology and structure response is computed by finite numerical technology.A passenger plane wing as an example,the example shows that the design method developed has significant practical value.
