Aerodynamical CFD Study of a non-lethal 12-gauge fin-stabilized projectile

The trajectory model for a subsonic fin-stabilized projectile at low angle of attack is typically a point-mass model (PMM). The disadvantage of this approach is the lack of prediction on the precision and the attitude of the projectile when hitting the target, because of a possible instability. The consideration of other forces and moments acting on the projectile in flight is an instructive step in the field of non-lethal ammunition trajectories.
