An overview of hypersonic test facilities, which continue to play a major role in the development of hypersonic vehicles, is given. In the past, ground test facilities were often used to perform configuration parametric studies and/or to develop large data bases. Future testing will emphasize understanding of fluid physics and validation of codes. Computational Fluid Dynamics (CFD) has made great progress in the past two decades, but the marriage of CFD and ground testing is clearly a reality today, and will become even more important in the future as computational and experimental researchers learn how to work together. One of the challenges for the experimentalist is to develop and utilize facilities that simulate hypersonic flight, and to provide the required data precision to validate CFD codes. Fundamental considerations of facilities and simulation issues are reviewed. It is clear that no one facility will meet the wide variety of test objectives; therefore, the test facilities span a range of size, run time, complexity, and operating cost. Representative facilities are described, as well as their test capabilities and their shortfalls.
