About
The TH-31 is a space engine from the Tianhuo series, developed by Space Pioneer (Tianbing Technology). It uses room-temperature liquid propellants and is suitable for spacecraft orbit changes and attitude control. The engine features a bipropellant pressure-fed system, using dinitrogen tetroxide/monomethylhydrazine (NTO/MMH) as propellants. It boasts a vacuum thrust of 3000N + 8*150N and a vacuum specific impulse of 310s. The TH-31 is designed for multiple starts, with a minimum of 2 starts and up to 2000 starts, and offers quick start acceleration of ≤0.3s. Its shortest working time is 0.5s, with a minimum working interval of 50ms, and a maximum continuous working time of 750s.
