      abstract = {The wave drag exerted on a body in supersonic/hypersonic flow is very critical and important problem of aerodynamic analysis. In order to minimize the drag force is essential to use a blunt body with a large nose radius which in turn induces drag for the vehicle motion. The present work involves study of supersonic/hypersonic flow around the blunt nose of an aero vehicle. Three different types of spike have been considered for the purpose of drag reduction studies.  Blunting of the front surface is considered in a certain sense as a way of thermal protection of an aero vehicle. But still, this blunted nose experiences the most intensive thermal action, therefore it requires thermal protection to even a greater extent than the peripheral part of the aero vehicle. The problem of wave drag can be alleviated by modifying the flow field in front of the body. One of the techniques to modify the flow fields is using retractable nose spike. In order to complement the numerically simulated results, they have been compared with the available experimental results.},
