Abstract

Methods for aerodynamic design and optimization based on Linear theory arenot well suited for modelling non-linear phenomenons. Their results only represent approximations of real optima. In the present study a new method based on non-linear theory, i.e. the solution of the Euler/Navier-Stokes equations, has been applied to improve these approximations. The structure of the system as well as the incorporated modules are described. Aerodynamic optimizations of a biconic re-entry capsule with respect to the lift-to-dragratio, the effective volume and the stability are presented and discussed. The method proves to be a robust and relative efficient tool for aerodynamic design of modem aerospace vehicles. An increase in the performance of computer systems will result in an increase in the efficiency as well. It is shown that the method keeps and sometimes expands the established knowledgebase of experienced engineers but reduces the design cycle times significantly.
