Hypersonic Scramjet Technology Enhancements for Hypervelocity Longe Range Interceptor Missile

"In a recent Army Scramjet Technology Evaluation Program, full scale scramjet models (Hyper-X and Air Force type configurations) were tested at fully duplicated flight conditions in the CUBRC LENS shock tunnel facility. This data in conjunction withhigh-fidelity CFD studies, has identified the status of hypersonic scramjet technology and areas where improvements that enhance performance are needed. Based on this study, we propose to examine effects of "conventional" changes to a baseline Mach 10-12Army scramjet (Hyper-X variant) on overall performance. We will also examine the gains in performance achievable via "non-conventional" changes suggested by recent research studies. Based on the findings in examining potential performance gains we willplan a subscale experimental program to be performed in Phase II in collaboration with Dr. Seiner at National Center for Physical Acoustic (NCPA)/U. Miss, and a full-scale experimental program to be performed in Phase II in collaboration with Dr. Holden atCALSPAN University of Buffalo Research Center (CUBRC). The full scale tests will entail modifications to the Army scramjet model and will be preformed in the LENS shock tunnel facility. The Phase I work serves to fill in major gaps in technology that havebeen identified by recent scramjet tests at CUBRC and accompanying CFD studies. Our commercialization strategy will parallel that of recent SBIR programs for high speed weapons dispense w
