Research Institution
The development of experimental diagnostic techniques is needed for characterizing particle dynamics within solid rocket motors (SRMs) for implementation in SRM modeling codes. Development of robust, accurate computational tools for predicting flow, heat transfer, and material response within SRMs can enable significant improvements in launch vehicle performance, development, life-cycle cost, and reliability. The Department of Defense (DoD) has identified the need for experimental characterization of particle size and dynamics throughout the motor from particle creation at the propellant burn surface to nozzle exit for accurate modeling of the internal environment of next-generation SRMs. Limited data are available to describe the particle size distribution, shape, and gas/particle velocity. The approach to the problem involves 1) reviewing available data and understanding its scope and accuracy, 2) defining priorities of the experiment regarding SRM locations and design parameters and data to be collected (e.g., particle size, shape, and velocity) for these locations and design parameters, and 3) demonstrating applicability, limitations, and improvements in state-of-the-art diagnostic tools for these experiments. The diagnostic techniques must provide data that are useful for optimization of modeling and simulation tools for motor designs. This will support current and future DoD ballistic missile and space launch applications.
