About
The Dawn Aerospace B1 is a flight-proven 1 N green bipropellant thruster using non-toxic nitrous oxide (N2O) and propene (C3H6) propellants. Operates in both bipropellant mode (74 mNs min impulse bit) and cold-gas mode (1.4 mNs min impulse bit) via spark igniter control. Supports up to 4 Hz pulse frequency and 18,000+ restarts. Launched on 50+ satellites in CubeSat and small satellite configurations. 100:1 nozzle expansion ratio.
