This presentation provides an overview of research and development on high-speed flight that JAXA is conducting collaboratively across the aviation and space fields under national funding. At the JAXA Aviation Technology Directorate, the Re-BooT (Robust En-route Sonic Boom Mitigation Technology Demonstration) project is underway. In this project, a demonstration vehicle incorporating “robust low-boom design technology” will be developed, and sonic booms generated during supersonic flight will be measured to verify the design. In addition, the project aims to carry out conceptual design using the validated technologies and to provide data that supports the development of international standards.rn The JAXA Kakuda Space Center is conducting research and development toward a ground-based demonstration of a turbine-based combined cyclern(TBCC) engine, composed of turbojet, ramjet, and scramjet for hypersonic vehicles. In parallel, fundamental studies on hypersonic airframe technologies are being carried out to address challenges in integrated vehicle–engine design. These efforts aim to establish key technologies required for future flight testing.
