The main intention of this project is to do relative analysis of Drag Reduction over Blunt Bodies at varied Angles of Attack in Supersonic Flow. In this project we have taken plain blunt body attached with different types of spikes which are like as 1. Blunt nose 2. Conical spike 3. Flat faced aero disc 4. Hemispherical spike 5. Breathing Blunt nose. For competitive analysis and results based on the different angle of attack with 0, 5 and 8 on that blunt body with spikes. Numerical simulation was carried out using CFD with SST komega model adopted. The hemispherical body is found to be efficient for reducing pressure in vicinity of blunt nose, while the flat plate found to be efficient in reducing peak pressure in compare to other. However, from the values of drag coefficient for all configuration the conical body is observed to have effective drag reduction compare to other bodies.
