WebAug 16, 2024 · Introduction. Flight dynamic characterization includes the prediction of aerodynamic forces and moments acting on the projectile and then the judicious choice of a trajectory model considering the forces and moments that have a significant effect on the position of the projectile in flight. WebAbstract. A projectile is stabilised using either gyroscopic or aerodynamic stability. But subcalibre projectiles with sabot have both spin and fins. Separate stability criteria are …
WebJan 1, 2013 · As the projectile dynamic stability increased, the radar data availability can be decreased. Finally, the proposed algorithm can estimate the projectile impact point accurately without computing the projectile initial disturbance, where different projectiles have different initial disturbances based on many factors, such as, gun barrel wear and ...
