Abstract
Aerothermodynamics analysis has become one of the necessary disciplines for a design and optimization of a space access vehicle. In this paper, thermal protection system (TPS) design and optimization for a vehicle similar to X-34 (such as ARES booster Figure 1) is discussed. The windward and leeward sides of the vehicle will be considered in this process. On the windward side, the air flow is assumed to be laminar and attached where a simple panel method IS used for aerothermodynamics analysis, while on the leeward side, where turbulent flow is separating from the vehicle, a panel method can not be used for this application. Instead, the Air Force Research Laboratory has developed a higher fidelity method to account for the physics of the flow field on the leeward side which is applied here for design and optimization. This paper will also discus in detail TPS design and optimization process and results for the ARES booster.
