Company Profile

On October 1, 2003, the Institute of Space and Astronautical Science (ISAS), the National Aerospace Laboratory of Japan (NAL) and the National Space Development Agency of Japan (NASDA) were merged into one independent administrative institution to be able to perform all their activities in the aerospace field as one organization, from basic research and development to utilization. The independent administrative institution is the Japan Aerospace Exploration Agency (JAXA.)

JAXA proposed its long-term vision, “JAXA2025,” to realize its own mission. The vision to demonstrate the technologies for hypersonic aircraft that can cruise at Mach 5 speed and cross the Pacific Ocean within two hours.

JAXA is developing the pre-cooled turbojet engine (PCTJ), which can operate from take-off to Mach 5 continuously. The engine has already demonstrated at ground experiments and a flight experiment up to Mach 1.8. Presently, Mach 5 flight demonstration using hypersonic technology experimental aircraft (HYTEX) is planned.

Contribution to HIKARI

JAXA will conduct performance analysis of pre-cooled turbojet engine (PCTJ), which can operate from take-off to Mach 5. The engine uses hydrogen both as coolant for pre-cooler and as fuel for combustor. The outline of our research is as follows;

  • Analyze the propulsive performance of pre-cooled turbojet (PCTJ) for high-speed transport application.
  • Analyze overall mass of the PCTJ.
  • Support the systems analysis of high-speed transport.

JAXA is contracted with the EC under the Grant Agreement No 313987 and being funded by the METI (Ministry of Economy, Trade and Industry) and other concerned Japanese authorities, in accordance with Japanese laws and regulations.
