AEROTHERMODYNAMIC TOPOLOGY OPTIMIZATION OF HYPERSONIC RE-ENTRY VEHICLE WITH AEROSPIKE BY USING CFD

Due to increasing demand of High Speed reentry vehicles for Space activities in the world, a major issue related to the process of slowing down a body is by the formation of stronger shocks that leads to extreme heat generated at the nose. The cost of thermal protection systems generally used to reduce the heat in the reentry vehicles is very high. So, there is a need of study to reduce aero heating in space vehicles. In this paper the eventual outcome is to reduce the aero heating, it is achieved by introducing a spike at frontal region of the nose. In addition, this spike is also used in avoiding the damage and preserving the structural integrity of vehicle over elevated temperatures. Further, by changing the geometry of the tip of spike yielded some better results. Hence, we suggest usage of spike in reentry vehicles is the most effective and economical over other protection systems.
