| Abstract: | Taking the dome of infrared air-to-air missile as the research object, using the heat flux obtained by engineering calculation approach on aerodynamic heating as input condition, this paper gives a brief analysis on the instantaneous temperature field and thermal stress of missile under the hot-carrier status, and verifies it by arc wind tunnel tests. Some numerical results are in good agreements with experimental data. The result shows that accuracy of the present approach is effective for engineering application. By adopting the analysis approach of this paper, some suggestion for improvement for to reduce the thermal stress of the infrared dome was put forwarded. |
| Keywords: | infrared dome aero heating temperature field thermal stress |
