High-Speed Flight Project Overview
What We do The High-Speed Flight (HSF) project develops technologies that make high-speed, airbreathing, commercial flight possible from Mach 1 to Mach 5 and above. HSF creates tools, technologies, and knowledge that will help eliminate today’s technical barriers to practical supersonic flight, most notably sonic boom. The project supports the X-59 quiet supersonic vehicle testing by gathering acoustic data and…
