Composite penetrator with enhanced lateral efficiency and based on active material and inert material

Abstract

The invention discloses a composite penetrator with enhanced lateral efficiency and based on active materials and inert materials, and relates to the technical field of penetrators with enhanced lateral efficiency. The penetrator with enhanced lateral efficiency comprises a front-section penetrator, a tail-section penetrator and one or more middle-section penetrators arranged between the front-section penetrator and the tail-section penetrator, wherein the front-section penetrator, the middle-section penetrators and the tail-section penetrator are in butt joint coaxially and sequentially, each of the front-section penetrator, the middle-section penetrators and the tail-section penetrator comprises a corresponding shell, a corresponding inner core and a corresponding sandwich part arranged between the corresponding shell and the corresponding inner core which are coaxially arranged in a sleeved mode, notch grooves are distributed in the outer walls of all the shells correspondingly, all the shells are made of the inert materials, and all the inner cores and all the sandwich parts are made of the active materials. The problems that an existing penetrator with enhanced lateral efficiency is single in damage mode, uncontrollable in fragment size and amount, low in penetrator body strength during high-speed penetration and the like are solved, kinetic energy and chemical energy combined damage and efficient damage to multi-layer target designated positions are achieved, and then the characteristics of impact energy release, fragment control, higher structural strength during high-speed impact and the like can be achieved.

Description

technical field [0001] The invention relates to the technical field of lateral effect enhanced bullets, in particular to a composite lateral effect enhanced elastic based on active materials and inert materials. Background technique [0002] Penetrator with enhanced later efficiency (PELE) is a new type of multifunctional kinetic energy ammunition, which does not contain high-energy explosives, does not have a fuze, and relies on physical effects to attack targets. The main targets are aircraft, ships, light vehicles, etc. Interval metal plate targets and reinforced concrete buildings, concrete fortifications, bunkers and other targets. The lateral reinforcement effect means that when the projectile interacts with the target, its strength is much lower than that of the shell. The inner core expands radially due to axial compression, thereby generating radial stress on the inner surface of the shell. When the stress is greater than the tensile strength of the shell material ...
