सार /ABSTRACT : Armor Piercing Fin Stabilized Projectiles (APFSDS) are used as primary ammunition for Main Battle Tanks (MBT). This type of ammunition uses its enormous amount of kinetic energy to penetrate and destroy the armor. An APFSDS system consists of a large length to diameter (L/D) ratio projectile which is stabilized with the fins, multi-segmented sabots, and an obturator, in general. The sabots are the critical components of the system and should be capable of withstanding very high pressures of the order of hundreds of MPa and transmit this pressure effectively to the sub-caliber projectile. However once the projectile sabot assembly exits the muzzle, sabot becomes a parasitic mass and should be discarded without causing any disturbance to the projectile trajectory. In this regard, the aerodynamic design of the sabot is crucial in terms of projectile dispersion. In this study, a modified analytical model is developed to evaluate the trajectories of various lift separation sabot configurations. The aerodynamic forces acting on the sabot surfaces during a supersonic flight are modeled in the present analytical model by incorporating the pressures on the windward side of the sabot due to the detached/attached shock and its reflections and then integrated using the 3-DoF dynamical equations. The trajectory and the aerodynamic coefficients were obtained for these configurations at a projectile Mach number of 3. The sabot configurations, which include two new designs, are compared with each other and with the conventional free flight trajectory data of the conventional sabots. The mechanical interaction between the sabot and projectile is also addressed in the present work. The comparison shows that the new designs with the aerodynamic surfaces close to the center of gravity, lift-off from the projectile with minimal mechanical interaction compared to the conventional sabot. Present study also consists of the shadowgraph visualization of a lit separation sabot which consists of an aerodynamic lifting surface at the trailing edge of the sabot. The interaction between muzzle blast and projectile is also successfully captured in the experiment.
