Calculation of a radiant heat flux for the base screen of the second stage rocket
A method for the solution of the equation of radiation transport by a method of the discrete directions on an unstructured three-dimensional grid is addressed in this article. Coefficients of radiation and absorption are assumed to be set by multigroup approach with spectrum base HITRAN and HITEMP. Calculation of a radiant heat flux is presented for the base screen of the stage II "Saturn V" launcher.

В работе излагается метод решения уравнения переноса излучения методом дискретных направлений на неструктурированной трехмерной сетке. Описан процесс вычисления коэффициентов излучения и поглощения для многогруппового приближения с использованием баз данных спектроскопических характеристик HITRAN и HITEMP. Приводится расчет лучистого теплового потока к донной области второй ступени РН «Saturn V».
