About
The HyNOx-200 is a large-scale green bipropellant thruster targeting 100-400 N of thrust for substantial spacecraft propulsion needs. It uses the self-pressurizing nitrous oxide and ethane propellant combination and is designed for high-delta-V missions requiring significant propulsion capability. Atmospheric testing has been completed with over 130 ignitions, and vacuum qualification is ongoing. The thruster features a mass of under 2.5 kg with flow control valves included, making it a compact and capable solution for medium to large spacecraft.
