LAYOUT OF HYPERSONIC VEHICLES BY COUPLING OF AERODYNAMICS AND FLIGHTMECHANICS

Abstract

Currently, the direct coupling of CFD and flight mechanics during the layout is still much too time-consuming to consider the free motion of a vehicle along a complete trajectory. Therefore, it is the goal to develop a modular coupling procedure between the trajectory optimization code REENT [1] of the Universität Stuttgart and the DLR surface inclination method SOSE [2], which in a later step also allows the use of the DLR Euler- and Navier- Stokes code TAU. Within the present paper the coupling procedure is introduced and basic but representative examples for sounding rocket and re-entry missions are discussed to prove the feasibility of the procedure.
