Abstract:
To realize the decoupling calculation of the internal and external coupling thermal effect of the multiple launch rocket control cabinet,the coupling heat transfer mechanism of the internal and external thermal environment of the multiple launch rocket control cabinet is analyzed,and an engineering calculation method of solving the internal and external coupling thermal effect of the multiple launch rocket control cabinet is established.The external heating effect of the combustion gas flow of the control cabinet is transformed into floating thermal boundary condition of the internal thermal analysis of the control cabinet when the multiple rocket launches continuously,avoiding a direct coupling solution.The transient heat condition in continuous launching is numerically simulated utilizing the above method and the internal transient temperature field of the control cabinet is obtained.The effects of some related factors are analyzed.It provides an important basis for designing finalization and relative research of multiple launch rockets.
