The Chemical and Physical Mechanism Processes of Al-Al2O3 within the Accelerating Flow-Field of Solid Rocket Motors (SRM)

Physical Sciences Inc. proposes to measure the Al-Al2O3 particle behavior in the supersonic plume of solid rocket motors (SRM) to ensure the development of a robust and accurate physics based exhaust plume flow field and signature prediction capability.An existing highly instrumented SRM ground based test facility will be used to conduct experimental measurements enabling the calibration and parameterization of motor performance and plume signature models. The targeted experimental measurements will acquire mechanistic understanding of the Al-Al2O3 particle distribution within the motors plume flow field and further the development of a comprehensive suite of sub-models that capture the particulate processes.
