Stardust

Stardust is a 35 N , NOS-Ethanol bipropellant, radiatively-cooled thruster for spacecraft attitude control and ΔV maneuvers.

The thruster includes two direct-acting, single-seat solenoid valves for fast startup and shutdown responses, an Inconel 718 cu alloy chamber and a multi-element gas centered venturi injector.

Venturi Injector

It uses the venturi principle to atomize the propellant and fuel.
