  In searching for payload mass fraction performance enhancement of human’s access to space technical capabilities, supersonic combustion ramjet (Scramjet) design study has been a long-term research effort in the aerospace community since the 1960’s1,2. Major programs were launched between 1984 and 1995, including NASA’s National Space Plane (NASP, X-30) program, which were unfortunately terminated in 1994 due to budgetary problem after the Challenger incident. However, a rich amount of research experience and test data was obtained during that period from design modeling, analyses and ground test programs.
  Scramjet propulsion provides promising opportunities for high-speed transportation and cost reduction for satellite and spacecraft launch operations. At the turn of the new millennium, new efforts in flight demonstrations have also revealed valuable research data and pushed the flight envelop closer to the ultimate goal of Mach 18~25 flight into space. Recent successes in flight demonstrations of Mach 7 to 10 flight speeds of the HyShot and Hyper-X programs have in part attributed to computational capabilities of the research teams in complimenting the understanding of the complex flow physics in this stringent and demanding flight regime. These new developments plus data collected in the past 45 years has laid a promising foundation for the aerospace research community that we are one step closer to the goal of reaching space and hypersonic air travel using scramjet combustion technology.
