SPECTRAL SCIENCES, INC — Department of Defense SBIR Phase II: The outcome of the proposed SBIR program will be the development of the Blow-down Large An

Description

The outcome of the proposed SBIR program will be the development of the Blow-down Large Angle-of-attack Signatures Thrust Termination Toolkit (BLAST3). BLAST3 will consist of a physics-based framework of modules for producing simulated imagery and radar scenes of solid rocket motor thrust termination plumes and debris, including time-dependent radar and infrared spectral signatures. This approach is based on several innovations including 1) a novel way of modeling debris generation in an SRM chamber, 2) the ability to generate chemical rates and radar and spectroscopic data for a variety of debris types including charred insulation, unburned propellant, and slag with novel crystal structures, and 3) a modular design that can be readily integrated to upgrade existing and next generation MDA engineering tools. Sources for debris to be examined include Al2O3/Al slag, unburned propellant and charred insulation. Radar and IR imagery calculated using the BLAST3 SRM model will be validated against available field data.
