Integrated Simulation System of Multi-physical Coupling Dynamics for Hypersonic Vehicles

摘要

The aeroelastic and aeroservoelastic problems considering the effect of aerodynamic heating are important aspects in designing hypersonic vehicles. To solve these problems, related techniques are researched including the methods of flow field, aerodynamic heating, three-dimensional temperature field, thermo-mode, unsteady aerodynamic force, thermo-flutter and aeroservoelastic stability. in the calculations of aerodynamic heating and unsteady aerodynamic force in complicated geometries, which are still difficult in pure Navier-Stokes solving for computational cost, two fast algorithms combined the CFD numerical simulation with the traditional engineering methods are proposed. By these above methods, the aeroelastic model for hypersonic vehicles is constructed and the simulation system of the coupling dynamics for hypersonic vehicles is built. Furthermore, some application examples are presented to validate the methods and software.
