SPECTRAL SCIENCES, INC — Department of Defense SBIR Phase I: Radiation from particulates can often be the dominant source of radiation in rocket plume

Description

Radiation from particulates can often be the dominant source of radiation in rocket plumes. Particulates such as soot and aluminum oxide emit and absorb light differently depending not only on their composition but also their size, temperature, and state of aggregation. These properties are influenced by a variety of external and physical phenomena that merit specialized attention. The Toolkit for Enhanced Particulate Simulation (EPSilon Toolkit) is a suite of physics submodels that includes the particulate specific details and will interface as a database generator and through a software library into the MDA plume signature codes. In Phase I Spectral Sciences teams with Corvid Technologies to bring the capability to compute from first principles the light scattering and extinction properties of multiphase particulates such as partially-molten or soot-coated alumium oxide. In Phase II this and other physics submodels will be integrated into the final software library and databases.
