China successfully tests new propulsion system for satellites
The state-run Chinese press today touted the successful use of a new “cold-propulsion system” on the Tiandu-2 test satellite launched into lunar orbit with its Queqiao-2 relay communications satellite.
The cold propulsion system recently provided high-precision orbital attitude control for the satellite during lunar orbit, marking the first successful application of the liquid ammonia cold air micro-propulsion system in the field of deep-space exploration.
The storage tank is an important component of satellite propulsion systems. As a pressure component, it requires not only high precision of forming and no leakage, but also good anti-fatigue performance, allowing for repeated fuel filling and discharge.
The article touts the tank so much because it was 3D-printed, making it the first such tank sent into space by China.
