Transitional Ballistics of Hypervelocity Projectiles.

Abstract The state of the art of transitional ballistics of hypervelocity fin-stabilized projectiles is described, particularly sabot launching from smoothbore guns. The influence of gun-tube vibration and aerodynamic jump on near-muzzle flight direction errors and dispersion is established whereas the gas dynamical effects are shown to be negligible. Detection techniques for gun-tube vibration are discussed and it is shown that muzzle contact and sabot separation induced trajectory perturbations can be observed by means of an electromechanical method, using (nontouching) inductive gages as well as strain gages. Results describing the firing of an 105 mm smoothbore tank gun are presented and analyzed for muzzle influence on free flight behavior.
