Techniques for Anchoring Debris Models

MDA is working to validate models for ejecta generated by solid motors. Minimal test data exists to validate current understanding of the phenomenology. MDA requires a means of anchoring detailed models for the generation and ejection of debris in a flight environment. IERUS proposes the development of an imaging system using lightweight sensors paired with advanced techniques for image generation which can be tested in a ground test and flown on flight vehicles. The IERUS imaging system will enable the use of fewer sensors than traditional imaging systems and can provide detailed imagery of both motor internals and debris exiting the nozzle. The proposed components are typically smaller, lighter, and cheaper than X-ray or other radiation based systems. Further, the IERUS system will provide full three-dimensional imagery, unlike an IR based system.
