Computational Modeling of Sense and Destroy Armor (SADARM) Submunition Separation/Collision.

Abstract

Sense and Destroy Armor (SADARM) is a high-priority Army program that experienced an initial design flaw, leading to submunition collisions. Computational fluid dynamics (CFD), including Chimera overset technology, has recently been applied to solve this problem. The CFD modeling has provided significant physical insight into the complex unsteady flow field associated with the SADARM submunitions during the separation/ejection process. CFD simulations have predicted that, with the addition of the fins on the trailing submunition, separation will occur, and collisions will be avoided.
