Electric Pump for Rocket Engines (PROPELLANT: LOX/LCH4)
Unlike conventional turbo pumps *1, our electric pump for rocket engines uses an electric motor as its driving mechanism. By electrifying the pump, we aim to provide new value in terms of engine maintenance and ease of handling. *2
*1 Turbo pump: A centrifugal pump that pressurizes liquid propellant by rotating with high-temperature combustion gas.
*2 Ease of handling: Makes thrust control easier.
Why LCH4
As a liquid fuel, methane has better storage properties than traditional liquid hydrogen in terms of density and difficulty in evaporation in space. Compared to kerosene, it is less likely to produce soot during engine combustion, making it less prone to failure during re-ignition or reuse. These advantages have attracted attention not only for use in Earth orbit but also in long-distance transportation to the moon and other planets. The electric pump is also gaining attention for its maintenance and ease of handling, and the adoption of liquid methane allows us to leverage its strengths.
