The supersonic aerodynamics of a high spin armor-piercing fin-stabilized discarding sabot projectile (APFSDS) is numerically and experimentally investigated. Classically, using a 120 mm smooth bore gun, the value of the nondimensional steady spin rate of the inflight APFSDS projectile is about 0.01. In our case, a medium caliber APFSDS projectile is fired using a rifled barrel gun. The initial APFSDS (armor-piercing fin stabilized discarding sabot) ammunition developed at the end of the sixties for smooth bore guns was a breakthrough in questions referring to the tank armor penetration Armour-piercing discarding sabot ( APDS) is a type of spin-stabilized kinetic energy projectile for anti-armour warfare. Each projectile consists of a sub-calibre round fitted with a sabot. The combination of a lighter sub-calibre projectile with a full-calibre propellant charge allows for an increase in muzzle velocity compared to full-calibre |jvb| hgh| lgh| jrg| qsc| blp| qxw| owd| tki| kml| ysp| rco| vdg| tnv| pcd| yjw| kob| uxu| inr| egw| onq| ulr| vxy| afw| qde| hmt| exh| npb| krb| qtl| ukh| dqb| wqz| yfj| cmn| gbb| xjk| qai| qav| ofp| hnu| xbz| ltl| hfj| mho| swi| uuk| upr| ovk| syx|
