In this project, we are going to analyze the effect of the Spike length and the shape of the spike on performance characteristics of body. For this, a reference model of a blunt nose is taken and Computational studies have been made to obtain the effect of a spike with a sharp tip and blunt tip on the flow over a hemi-spherically blunt body at different Mach numbers. Effect of spike length has been obtained and it is observed that increase in spike length reduces drag at supersonic speeds and the drag reduction due to shape is based on the Mach number and the shape of the spike. The project suggests that an adjustable spike system at the nose of the aircraft can improve the aerodynamic performance at small weight compensation.
