The primary purpose of this proposal is to study and demonstrate the feasibility of building a fast-running physics based simulation of a warhead that dispenses several independent submunitions from the warhead using a Windows based PC to host the simulation. In the simulation system to be… More

To accurately model dispensing events in conceptual AF and Navy dispensing munitions, the simulation framework used to build the simulations must incorporate fast, accurate, scalable physics engine algorithms as well as robust interacting aerodynamic flow estimation. The Phase I SBIR effort… More

This effort will identify and model the critical functional/physical system and subsystem requirements, components, subcomponents, and key performance parameters for a shock response spectrum test facility that is capable of multi-axis fuze testing.

The proposed capability will model the debris flyout and the rubble volume resulting from a munition detonation. Fidelity will be tunable so that an application can model rubble effects ranging from a low fidelity point feature with volume and dimensional attributes, to a medium fidelity areal… More

Design, fabricate and test a prototype for an apparatus capable of repeatable, multi-axis shock testing in loading regimes representative of the design-critical regimes experienced by a sensor mounted in a penetrating munition.

The Army currently has a need to model debris flyout and subsequent rubble pile generation from munition detonations in urban areas. Munitions may include various types of IEDs, artillery rounds, RPGs, and air delivered munitions. Rubble sources include building structures consisting of concrete,… More

ABSTRACT: When a structure breaks up following a blast event, it allows the blast wave to propagate through a new opening into another airspace; this continuation of the blast wave is called"secondary blast"and may cause damage to elements in the other airspace. Each step in this process… More
