Research On The Damage Performance Of PELE Attacking Low Altitude Target

Penetrator with Enhanced Lateral Efficiency (PELE) is a novel kind of low-cost,multifunctional, high security and low incidental damage ammunition, and has the functionsof both armor-piercing projectile and high-explosive projectile. PELE can be widely appliedto the fields of air defense, anti-missiles and anti-armor, and it is especially suitable for urbanwarfare because of its low incidental damage property. Helicopter AH-64D is one of the mostadvanced and powerful armed helicopter in the world and it is of great significance to studythe damage performance of PELE attacking AH-64D.Through theoretical analysis and numerical simulation methods, the functionalmechanism of PELE, the key factors of that influence the damage efficiency of PELE,especially PELE’s damage efficiency on AH-64D are studied systemically, which wouldprovide a theoretic and technical reference for the design, application and improvement ofPELE. The followings are the main contents of this dissertation: Through numericalsimulation method, the influence of the materials, structures, velocity, impact angle of PELE,and characteristics of the target on the damage performance of PELE are analyzed; Theconception of half-premade fragmented PELE is proposed based on PELE, and the keyfactors that influence the damage performance of the novel ammunition are analyzed; Theequivalent models of the critical components of AH-64D are established, and the damagemechanism and level of armed helicopter are investigated; The damage performance of bothPELE and half-premade fragmented PELE on AH-64D is analyzed, and the damageperformance of the two projectiles is compared.
