Abstract

The paper focuses on the importance of a good geometrical representation of re-entry vehicles for hypersonic Row simulations by means of CFD. Based on investigations carried our by DLR throughout past re-entry programs, it is shown that in many cases geometrical simplifications of configurations used for CFD evaluation introduce errors in aerodynamic and aerothermodynamicquantities comparable or even higher than those arising from numerical accuracy or lack of physical modeling of the respective code. Since it is veryoften not possible to upgrade an already existing configuration due to layout incompatibilities of the grid, a good practice is to include as many details as possible in the initial grid design.
