2020 Hypersonics Course

The national security of the United States is currently threatened by the development in other countries of highly maneuverable hypersonic weapons systems with very long range and flexible trajectory capabilities. These can operate both within the atmosphere or in suborbital flight. Such vehicles overcome the weaknesses of intercontinental ballistic missiles resulting from their readily predictable and easily tracked flight paths. The inauguration of the new U.S. Space Force USSF) is a recent step in the provision of “prompt and sustained space operations,” which would clearly oversee the development of an appropriate response to the threat of hypersonic weapons systems.

This four-day short course is designed to provide an in-depth review of the current state of hypersonic flight technology with a focus on the application of this technology in the design and operation of hypersonic missiles, cruise vehicles, defensive systems, and single-stage to orbit operations. A detailed picture of all aspects of the required technology is presented; access to the vast literature on the engineering principles of hypersonic vehicle design is provided.
