Advancing LOX/LCH4 Dual-Propellant Cooling for HANBIT-Micro
INNOSPACE has successfully completed a series of combustion tests for its upgraded 4 kN-class liquid-methane kick-stage combustor for HANBIT-Micro.
Building on the 237-second long-duration ground test in May 2024, the combustor has been advanced with a Dual-Propellant Regenerative Cooling scheme.

 Unlike conventional single-propellant regenerative cooling, this approach utilizes both fuel and oxidizer as coolants, enabling:
 Reduced feed pressure requirements
 Lighter propellant tanks
 Lower overall kick-stage mass

 By preheating and vaporizing both coolants, the system also achieves:
 Improved mixing efficiency
 Shorter ignition delay
 Enhanced combustion stability and efficiency

 Overcoming High Technical Barriers
Most notably, the recent test validated stable regenerative cooling under low-pressure, subcritical conditions — a technically demanding regime — and mitigated the risks associated with using liquid oxygen (LOX) as a coolant.
The application of a gas–gas swirl injector further demonstrated improved mixing performance.

With this milestone, INNOSPACE continues to advance methane propulsion technology and enhance the maturity of the HANBIT-Micro kick-stage system.  Please stay tuned for the next phase of development.
