Overview
PBR-50 (Water Resistojet Thruster) is a water vapor propulsion system in a Φ250 x 300 mm form factor with high thrust and total impulse, optimal for 100-200kg microsats. It is a fully integrated system that incorporates thruster head, fluidics, electronics and propellant tank, and is clusterable to meet a wide range of spacecraft sizes. The PBR-50 uses water as propellant and does not require a high-pressure storage. The propellant is preloaded to the tank prior to delivery from factory so that satellite integrators would not have to deal with complex fueling work. The propulsion system was launched in 2024, and is waiting for the operation.
