Thermal-structural coupling analysis on wing short-range hypersonic missile

As to the issue that aerodynamic heating has great effect on the structure of hypersonic missile wing,a finite element model of the short-range hypersonic missile wing is established.The temperature distribution,stress and displacement of the wing are calculated with ANSYS under the cases of aerodynamic load,thermal load and aerodynamic-thermal load.The results indicate that stress and displacement of the wing are mainly aroused by temperature grads.Therefore,the hypersonic missiles,the heat-protection measures should be taken at the high-temperature zone of the wings,which ensure their structural intensity and stiffness are more reliable.
