Numerical Investigation of Coupling Effect on Structural Deformation of Supersonic Missile

Abstract

The small slenderness ratio supersonic missile model is simulated by method of fluidthermal- solid interaction. Numerical simulation results on structure show that: the structure on longitudinal is stretched and on axial direction is expanded when attack angle is 0; the structure on longitudinal is bended and deformation increases with increments in attack angle. Taking coupling factors into account: stretch in length of the structure is caused by thermal factor; blending deformation on structure is due to thermal factor and aerodynamic force.
