 Abstract:

An evaluation of aerodynamic forces and moments that act on an irregularly shaped body (fragments of HE projectile) moving at high velocities was made, using numerical simulations, analytical models, and CAD methods. Using the results obtained for aerodynamic forces and moments, and known values of body exposed area, aerodynamic drag and lift coefficients were determined for different body orientations and different flow velocity. Analysis of the influence of the body front surface and body slenderness on the position of the maximum CD value (on the CD (Ma) curve) was performed.
