In this work, the numerical and experimental approach was used to study the aerodynamic performance of power series nose cone profiles. The aerodynamic characteristics such as pressure, axial velocity, total drag, dynamic pressure, skin friction coefficient, etc. for the aforementioned nose cone profiles were explained for low subsonic speeds for the same length to diameter ratio. The simulation involved a velocity of 25 m/s, calculated for zero degrees angle of attack to demonstrate the flow behaviour around the nose cone profiles. The data obtained from the numerical analysis of the nose cone shapes were compared with the experimental data obtained from the wind tunnel analysis in order to find out the deviation between static pressure, coefficient of pressure and velocity. From the study, it is concluded that nose cone having power 0.25 has the least coefficient drag at low subsonic speed, so 0.25 power nose cone has best aerodynamic performance among all of the investigated nose cone profiles.
