Abstract
Concept of an active protection system on combat vehicles with high-explosive fragmentation interceptor projectile is presented in this paper. Development process and characteristics of the active protection system are highly dependent on performance characteristics of an interceptor projectile. The interceptor projectile generating frontal spray of steel spherical fragments was considered. The research on design features of contemporary rocket-propelled anti-tank projectiles was done in order to define required capabilities of the projectile for active protection systems. Vulnerability of an anti-tank projectile was analyzed according to its dimensions and design of main subsystems. Representative models of different types of anti-tank projectiles were considered for vulnerability assessment. Results of minimal fragment number density and minimal impact velocity are presented and the most significant conclusions are made.
Highlights
PROTECTION is a key element of survivability of a combat system
Capabilities of an interceptor projectile with fragmentation effect have been assessed according to the vulnerability of various AT projectiles with a HEAT warhead
For 0° interception angle, approximately 300 fragments per m2 are needed for one hit in the frontal surface of 64-72 mm AT rockets used in modern individual light AT weapon systems with 150-300 m effective range
Summary
