About
The Dawn Aerospace B20 is a 20 N green bipropellant thruster designed for small satellite main propulsion and attitude control maneuvers. Uses the same non-toxic N2O/propene propellant combination as the B1, with dual bipropellant (0.98 Ns min impulse bit) and cold-gas (10 mNs) operating modes. Supports 10,000+ restarts at 4 Hz pulse frequency. Launched on 100+ satellites in orbit. 100:1 nozzle expansion ratio.
