AFRL Propulsion Unit for Cubesats (PUC)

The VACCO AFRL Propulsion Unit for Cubesats(PUC) is a delta-v propulsion system specifically optimized for CubeSats. The propulsion module is available in a variety of sizes from 0.14U to 1U with features that include minimal payload displacement, high delta-v, low mass, low power and a simple control interface.

Development hardware has been extensively tested including 75,000+ cold gas firings in a vacuum chamber.

The self-contained propulsion system includes an integral controller,propellant storage, propellant feed system, sensors and a 5.4 mN warm gas thruster. Reliability is ensured through simplicity of design, welded titanium construction and frictionless valve technology.
