The hollow projectile known as a tubular projectile is an important parameter to be considered to improve its performance characteristics greatly. The design parameters of a projectile depend on the drag and lift forces acting on the projectile. Therefore, a detail experimental and simulation are required to understand the projectile performance against the wind. In this study, experimental and numerical investigations of a hollow shape projectile under different wind conditions are carried out. Here a 105 mm hollow shape projectile is used in while performing the experiment. The experiment is carried out by placing the projectile in front of the wind tunnel. The simulation was done using software at an Angle of Attack (AOA) 45°, keeping wind velocity and geometry the same. The pressure coefficients were calculated from the measured values of the surface static pressure distribution on the projectile. The drag and lift coefficients were further obtained from the measured pressure and a projected area of the projectiles. The wind flow effect on the projectiles was also analysed by ANSYS software. The simulation and experimental result show similar trend regarding drag and lift forces.
