The "National Aerospace Laboratory" was a governmental establishment dedicated to aeronautical research and development.

-Jointly with MITI (Ministry of Industry) and IHI they made a turbofan engine of more than 11,000 lbf of thrust, known as the FJR / 710.

-This gave way to improved versions such as -720 and -722.

-The FJR / 720-600S was the most tested. It is a double shaft turbofan engine.

From Appendix 6: Scramjet engine trials were also carried out in Japan, specifically at the National Aerospace Laboratory (NAL).

-They were built by Mitsubishi Heavy Industries with an estimated power of 15 tons of thrust. With a concept similar to the American X-30.

-The engines used for flight at high Mach, between 5 and 20, are LACE or Liquid-Air Cycle Engines, for low speed and high speed thrusts.

-For take-off it uses conventional turbines and for orbital maneuvers it has rocket engines, mainly in the tail.

-The Scramjet engine is the rectangular box under the spaceship, at the rear.

From Appendix 11: In 2003 NAL merged with ISAS and NASDA to form JAXA
