To address the foregoing needs, the part of our research dealing with multi-body interactions we performed research to study store interaction with cavity bay shear layers relevant to separation and delivery with emphasis on the following tasks 1. Continue combined asymptotic and numerical modeling of store separation and multibody flow processes 2. Investigate shock interactions relevant to stage separation 3. Develop combined dynamics and aerodynamic models for analysis of store and stage separation 4. Calculate examples of a slender body separation from a wing into a supersonic freestream Added to this scope of effort our objective was to develop the ultrasonic absorption coating technology so that ultimately it can be deployed on hypersonic flight vehicles for passive laminar flow control. A major objective was to mathematically simulate the energetics related to admittance of typical thermal protection system microstructures to tailor them to absorb energy of second mode instabilities leading to delay of laminar turbulent boundary layer transition.
