Abstract:

This paper describes the Fast Air-Target Encounter Penetration FATEPEN model used in the design, development and evaluation of new anti-air weapon systems. FATEPEN is a set of fast running algorithms that simulate penetration of and damage to, paced target structures by compact and noncompact warhead fragments, and long rods at speeds up to kmsec. Our paper begins with a discussion of the role of simulation in the development of weapons systems and more specifically in the design of anti-air missile warheads. The FATEPEN terminal interaction model is then described including our approach to penetration model development, illustrations of high velocity penetration characteristics addressed by the code, a listing of the models required for accurate effects simulations, and an overview of the FATEPEN computer code including sample model predictions. The paper concludes with brief descriptions of FATEPEN documentation, the current code validation database, the corresponding code prediction accuracy statistics and a summary of current FATEPEN usage in the weapons system effectiveness community.
