the Von Karman nose cone, which is derived to minimize drag for a given length and diameter. The equation defining Haack Series cones is shown below: 𝑟=1 √𝜋 √𝜑−1 2 sin2𝜑𝐶sin3𝜑 (Chin, 1961) Where: 𝜑=cos−1(1−2𝑥)and C = 0 for the Von Karman and 1/3 for the L-V Haack Series.
Fig-15 Pressure and Mach contours for Von Karman nose cone. Fig-16 Showing C p variation along the nose cone. Fig-17 Showing Mach number variance along nose cone. On evaluating the plots and the numerical contours it can be clearly seen that the Von Karman nose cone has least vortex strength. Because of its profile the flow is speeding slowly

Jan 1, 2022 · The main challenge is that the nose shape being the foremost part of the missile, experiences high aerodynamic loads which must be resisted by the compressible motion of the fluid for optimum performance at supersonic speeds. The research aims to compare the Conical and Ogival nose cone shapes of the supersonic missile at Mach 2.0.
