Aerodynamic parameters have a huge impact on a projectile trajectory, which in turn results in its range and accuracy. The influence aerodynamic parameters for the estimation of trajectory elements are drag Coefficients, lift Coefficients, attack angles, muzzle velocity, atmospheric conditions, and the projectile shape and size. Thus proper methods for determining the drag and lift forces of the projectile is very important. The trajectory of a projectile through the air is affected both by gravity and by aerodynamic forces. In this paper, 57 mm and 37 mm anti-aircraft projectile was considered for the AnalysisAnalysis. Her main emphasis was given to determine the pressure coefficient, Drag coefficients, lift coefficient of the projectiles at different attack angles. The experiment was conducted in an open circuit subsonic wind tunnel to study the aerodynamic parameters where the uniform flow velocity is maintained across the flow direction. For the investigation, varied angles of the attack were considered. Here inclined manometer was used to determine the static surface pressure, and the pressure coefficient was determined from that. Then the drag & lift forces and their coefficients were determined. Finally, for the computational AnalysisAnalysis, the ANSYS Software was used to simulate the experimental data.
