Coupled with the structural equations, the models for transonic aeroelasticity in state-space are got. 耦合結(jié)構(gòu)動(dòng)力學(xué)方程,建立了基于狀態(tài)空間的跨聲速氣動(dòng)彈性分析模型。
The main difficulty on the study of aeroelasticity lies in the effects of unsteady separation, shock and viscosity to the stall flutter. 振蕩葉柵的非定常分 離、粘性效應(yīng)和跨音激波對(duì)失速顫振的影響成為當(dāng)前氣動(dòng)彈性力學(xué)的 主要難點(diǎn)。
However, this new structure also leads to some problems in strength and aeroelasticity, so some analytical results and suggestions are presented. 但是這種新型的結(jié)構(gòu)也帶來了強(qiáng)度、氣彈穩(wěn)定性等問題,對(duì)此給出了一些分析結(jié)果和建議。
