Checking computation data on radiative and convectional heating of next generation spacecraft

Abstract

The results of testing correlation equations in calculating convective and radiative heating of landers are presented for the examples of Apollo 4 and Stardust, for which we have a great amount of numerical data by other authors. Using these correlation dependences, the analysis of heating of the landing module is performed in the flight experiment Fire-II. With the use of special developed two-dimensional and three-dimensional computer codes NERAT(2D,3D)+ASTEROID, we performed calculations on radiative-gasdynamics at some entry points on the trajectories of the Stardust and Fire-II landers. The correlation dependences and computer codes NERAT(2D,3D)+ASTEROID were used in giving a prognosis of the aerothermodynamics of promising spacecrafts of large size. The reasons for the discrepancy in numerical data are discussed.
