The First Reusable Open Cycle LOX / Kerosene Engine in China

With 40 tons Variable Thrust

As the main power of the first stage (7 sets) and the second stage (1 set) of the Pallas-1 liquid carrier rocket, the Welkin liquid oxygen/kerosene engine is a circulating liquid rocket engine with variable thrust gas generator that has been started many times. Each Engine rated thrust 40 tons of sea level, working condition of maximum thrust sea level 50 tons (the first level one Engine - out ability), the working condition of minimum sea level thrust 10 tons (variable thrust ratio 4:1), variable thrust meets the demand of booster level drops and a soft landing, The engine is capable of repeated use and fault detection and isolation. Repeat use 50 times on each engine, with the ability to plus or minus 6 ° swing and engine thrust-weight ratio than more than 120.
