Comparative Study of Different Missile Shapes using Computational Fluid Dynamics

Aerodynamics study using computational fluid dynamics is very famous among the engineers and scientists, because it not only reduces the cost of the entire project but also saves a lot more time. The results of the CFD simulations needed to validate through experiments. So, we can say that CFD simulation studies reduce the no. Of experiments taken, if it cannot eliminate. In this research paper, we made four different aerodynamics missiles shapes CAD models in solid works by using underlying principles, mathematical equations of different curves and engineering judgement, one of them is a missile of standard basic shape. We have analysed and compared them with basic shape of missile. Here, in this study, Volume is taken a constant parameter. Drag Coefficient is the main parameter which is evaluated and studied at different Mach no’s and at a constant angle of attack. Reasons behind the magnificent drop in drag coefficient explained in discussion section.
