Liquid Butane Propulsion
Description
Application History: Ten units with flight experience, with the longest time in orbit exceeding 3 years. Among these, 24 units of 20mN thrusters have served the core module of the space station's high-microgravity suspension experiment system and completed their in-orbit missions. The product has received high overall recognition.
Application Scenarios: Suitable for spacecraft under 100kg where cost, power consumption, and installation layout are strongly constrained. It is also the best choice for de-saturation, momentum wheel unloading, and rapid fine attitude control.
