Summary
The Dawn Aerospace B1 Thruster is a green chemical propulsion thruster utilized as the central thruster in Dawn’s CubeDrive propulsion modules. It can be also utilized as a modular building block within Dawn's turn-key SatDrive systems.
The B1 thruster can be positioned throughout the spacecraft, in clusters, and at various cant-angles. Its assembly includes the thruster body, valves, and control electronics. With standard data and power interfaces, thrusters are easy to command and operate.
It utilizes green propellants - nitrous oxide (N2O) and propylene (C3H6) - which are self-pressurizing and do not require external pressurant, high-pressure regulators, or mechanical PMDs. The thruster can also operate in both a bi-propellant and cold-gas mode by controlling the spark igniter.
