DESIGN AND ANALYSIS OF SURFACE TO SURFACE MISSILE
Abstract — The main purpose of the project is to propose that the obsolete and old surface to air missiles can be used as surface to surface missiles because old missiles can’t follow complex trajectory of the present highly maneuverable target. Hence they can be used to hit a stationary target which is on ground with sufficient accuracy. This is the best way to use these old missiles than abandoning them. In this project, a 50 Km range surface to surface missile is designed based on old existing surface to air missile. The aerodynamic theory has been adopted to evolve the airframe of missile. The dimensions of surface to surface missile taken from old existing surface to air missile are plotted in CATIA V5R20. We simulate a flow of Mach 4 over the 3D model of missile using the software CFX. We find out the pressure, velocity, density and temperature variations. Finally we plot the trajectory in mat lab and obtain the following graphs: Range vs. Time, Altitude vs. Time and Velocity vs. Time.
