Performance analysis on varies bluff bodies at hypersonic speed

At hypervelocity flows the design place a major role. To sustain such impact the design, need to be more aerodynamic. Blunt body is key factor to achieve and sustain those hypersonic velocities that is mainly focused beyond Mach number 5. Blunt body design in aerodynamic and structural aspects become more crucial factors in hyper velocity vehicles. The paper mainly focuses on effective blunt body design. In order to achieve the effectiveness various radius of curvature taken into account and comparative study were done. Along with that flow compressibility, chemical reaction, aerodynamic heating, stagnation conditions were discussed. Extensive review was done to select most efficient blunt body design in both aerodynamic and structural aspects.
