Airfoil flutter is one of the important problems in aeroelasticity. 在气动弹性力学中,机翼振颤是一个非常典型的问题。
Aeroelasticity Matters: Some reflections on Two Decades of Testing in the NASA Lanley Transonic Dynamics wind Tunnel. 气动弹性问题:nasa兰利跨声速动力学风洞20年试验的几点思考。
Coupled with the structural equations, the models for transonic aeroelasticity in state-space are got. 耦合结构动力学方程,建立了基于状态空间的跨声速气动弹性分析模型。
The main difficulty on the study of aeroelasticity lies in the effects of unsteady separation, shock and viscosity to the stall flutter. 振荡叶栅的非定常分 离、粘性效应和跨音激波对失速颤振的影响成为当前气动弹性力学的 主要难点。
However, this new structure also leads to some problems in strength and aeroelasticity, so some analytical results and suggestions are presented. 但是这种新型的结构也带来了强度、气弹稳定性等问题,对此给出了一些分析结果和建议。
