  • The calculation of supersonic missile temperature distribution plays an important role in the study of its infrared characteristic. Two primary radiation points of supersonic missile-fuselage and plume, were analyzed deeply. A temperature distribution model of supersonic missile was built, and the feasibility was proved by simulation. Firstly, a theoretical model and semi-empirical formula were adopted to calulate the temperature distribution of supersonic missile. Secondly, in the model, the plume was disposed as supersonic circular symmetrical adiabatic isentropic airflow approximately. The distribution of air airflow parameters were calculated by the characteristic method line. Thirdly, a theoretic model and calculation method of the plume shape were established. Finally, taking one missile as an example, the computing model was used to compute the temperature distribution of supersonic missile. The results indicate that this is an effective method to calulate the temperature distribution of supersonic missile according to the comparison between the result values and the measured values.

Abstract: The calculation of supersonic missile temperature distribution plays an important role in the study of its infrared characteristic. Two primary radiation points of supersonic missile-fuselage and plume, were analyzed deeply. A temperature distribution model of supersonic missile was built, and the feasibility was proved by simulation. Firstly, a theoretical model and semi-empirical formula were adopted to calulate the temperature distribution of supersonic missile. Secondly, in the model, the plume was disposed as supersonic circular symmetrical adiabatic isentropic airflow approximately. The distribution of air airflow parameters were calculated by the characteristic method line. Thirdly, a theoretic model and calculation method of the plume shape were established. Finally, taking one missile as an example, the computing model was used to compute the temperature distribution of supersonic missile. The results indicate that this is an effective method to calulate the temperature distribution of supersonic missile according to the comparison between the result values and the measured values.
