Reusable Agile Gas Arching MethaLOX engine delivering high-efficiency staged combustion thrust for orbital-class vehicles.
RAGAM is a next-generation cryogenic engine developed to meet the evolving demands of orbital and deep-space missions. Fueled by liquefied methane and liquid oxygen, it uses a staged combustion cycle to achieve high thrust-to-weight ratio and exceptional reusability. The engine is designed for modular integration across launch vehicles from small-lift to super-heavy configurations.

88 tons (vacuum), 75 tons (sea level) class
Regeneratively cooled copper-alloy chamber with high-expansion cryogenic nozzle
Full-flow staged combustion cycle with methane-rich preburner
Designed for 20+ reuse cycles with minimal refurb time
Dual-axis hydraulic gimbal system ±6° for flight control
Primary propulsion for reusable boosters, upper stages, and lunar transfer modules
RAGAM leverages high-temperature nickel alloys and Monel-class supermetals in its chamber and turbopump housing, optimized for sustained operation under cryogenic and high-pressure oxygen environments. Regenerative cooling paths are intricately cast and 3D printed to maximize wall longevity while preventing hot-spot formation during long burns.
