Rocket Link Technology, Co., Ltd. (President and CEO: Yasuhiro Morita) has released an accelerated development plan to realize its space transport service.
The company aims to reduce costs and increase the frequency of space transport through the development of its innovative solid rocket fuel, LTP (Low Melting Temperature Thermoplastic Propellant). Based on the progress of LTP development and successful ground combustion tests, the company aims to reach the mesosphere and space within one year by conducting a practical sounding rocket-class flight test, as one of the staged demonstration tests toward service realization around 2030.
As of this release, the cumulative funding amount has reached 2.45 billion JPY.
■ Characteristics of LTP
Conventional solid fuels use thermosetting resins, requiring precise manufacturing processes taking 2-3 weeks. In contrast, LTP allows for reversible molding via natural cooling, enabling short-time production, refilling, repair, and reuse of propellants. Consequently, it can be manufactured not only by specialized manufacturers but also by general manufacturers.
■ Overview of Flight Test
Having already succeeded in a 5km altitude test with a 135mm diameter rocket, this test will apply the propellant to a practical sounding rocket-class motor to reach space.
