PASCC1: Picatinny Arsenal Shaped Charge Code, One-Dimensional Analysis Version 2.1

摘要

Picatinny Arsenal Shaped Charge Code, One-dimensional Analysis Version 2.1 (PASCC1) is a phenomenalogically based one-dimensional shaped charge program resident on the CDC 825/74c at Picatinny Arsenal. PASCC1 has the capability of modeling a large variety of shaped charges, including shaped charges with: axial explosive composition and density gradients, detonation wave shapers. variable body geometries, variable explosive charge geometries, and variable liner geometries. The shaped charge liner is treated as a series of liner points (mass points). The program uses accelerating Gurney formulation with constant gamma explosive products polytropic expansion to predict the acceleration of each liner point. The collapse angle of the liner is calculated using a modified Taylor Angle formulation, which compensates for liner point acceleration. The shaped charge jet parameters are calculated using the Pugh-Eichelberger-Rostoker jet/slug formulation. Shaped charge, Computer program, Wave shaping, Gurney formulation. (JES)
