SBIR-STTR Award

We propose to develop an analysis/tool integration architecture to enable the synergistic exploration and capture of the critical features of the penetration fuze environment found within combined experimental and computational datasets. We will develop a design of the architecture and investigate the required capabilities of the architecture (software and hardware). We will implement a subset of the complete architecture as a prototype and perform preliminary modal data mining to demonstrate the efficacy of the approach to hard target fuze penetration environment characterization. As this effort proceeds into Phase II, we envision the development of a systematic design of experiments methodology that can perform data mining on the complex underlying database, ultimately serving as a fuze design tool for survivability and performance.

Benefits:
The tool developed in this SBIR will enable the government to integrate the tools required to perform penetration data generation, analysis, and mining to characterize the complexity of the penetration environment dynamics. It will address a number of challenging features from the efficient access and management of the underlying database to the incorporation of tools that can analyze the data and identify metrics capable of mapping a survivability envelope of fuzes and predicting their failure. We focus on aspects of the canonical problem domain in which complex weapon target interaction drives the development, modeling, and testing of penetrating weapons and their associated fuzes. By using the tools from this SBIR, contractors and government agencies will be able to create integrated analysis plans that span the test, simulation, and analysis domains, encouraging reuse of algorithms, tools, and analysis packages without the challenges of consideration for the ability to use data across the domain boundaries.

This Phase II proposal includes a design for an analysis/integration architecture including full implementation and testing of the multi-core architecture during Phase II. During the Phase I effort, we implemented a substantial subset of the complete architecture as a prototype and performed some preliminary data mining to demonstrate the efficacy of the approach to hard target fuze penetration environment characterization. We envision the development of a systematic design of experiments methodology that can perform data mining on this complex underlying database, ultimately serving as a fuze design tool for survivability and performance. The methodology will exploit the available experimental data, as well as set up and perform additional simulations as required to fill in critical gaps in the data.

Benefits:
Implementation of the DAMPED Architecture allows users and simulation developers to provide capabilities to support cross-domain data/algorithm utilization, tool integration; constructs for creating/managing computational flows; support data mapping, standardization, transport, and transformation; handle massive data from tests or simulations, and flexible data storage and management capabilities. Anyar expects many of the contractors performing warhead penetration analysis will apply the process/data algorithms developed for DAMPED to warhead structural/fuze response estimation as tools in their fuze survivability projects. The algorithms will provide a robust tool for estimating the complex loading environment for fuzes and these capabilities will enable the government and vendors to incorporate, fast running (orders of magnitude), hydrocode level results into simulating warhead/fuze survivability against a broad spectrum of targets using the DAMPED database and tools.
