Evaluation of Selected Computer Models for Modeling Pyrotechnic and Propellant Devices

Abstract

A variety of analytic computer models are available and have been used successfully to predict performance in pyrotechnic systems, providing an inexpensive and quick method for initial validation of the performance of a system design. The authors have assessed several of those available at Naval Ordnance Station, Indian Head, MD, including several of the standard thermodynamic codes (NASA-Lewis, PEP, BLAKE, TIGER) as well as lumped parameter ballistic codes (CADPROG, EBED, ROCIGN), delay burn rate codes (HARDT), and ignition requirements analysis (Bryan-Lawrence). The use, characteristics, and outputs of the various codes are discussed with emphasis on limitations and cautions required when applying these techniques to predict performance of pyrotechnic systems. Keywords: Computer modeling; Thermochemical modeling; Ignition modeling; Pyrotechnics; Ignition; Cartridge actuated devices; Igniters.
