Hypersonic vehicles or engines usually employ complex thermal protecting shells.This sometimes brings multi-physics difficulties, e.g.

, thermal-aeroelastic problems like panel flutter etc.This paper aims to propose a novel optimization method versus thermal dynamic influence on panel vibration.A traditional panel structure was modelled and analyzed.

After analyzing its dynamic characteristics of panel flutter, thermal effects were also included to propose thermal-aeroelastic analysis results of the present hypersonic panel.Then, a MMC (Moving Morphable Component) new belial model method was proposed to suggest dynamic optimization for such panel structures.The proposed method can provide arbitrary frequency dodge warlord for sale control result in order to suggest a newly generated panel structure.

Based on the optimal structures, dynamic analysis was presented again to verify the effectiveness of the optimization method.So aero-thermo-dynamic characteristics of the optimal panel structures could be investigated.It can be seen that the computational results presented significantly improved panel flutter results.

The proposed dynamic optimization method can be employed for the design of panel structures versus high combustion temperatures or hypersonic aerodynamics.
