THRUSTER SUMMARY:
A110 is a 111 N (25 lbf), M20 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, a refractory-metal chamber and nozzle, and a low-dribble volume multi-element injector. The additively manufactured injector enables precision pulses of less than 5 milliseconds and high-performance steady-state operation.
A110 has undergone an extensive hotfire test campaign in the flight configuration, with a total on-time of 1200s+ seconds across a variety of test conditions.
A110 hotfire test in Agile Space Industries' 'Sunshine' Vacuum Test Stand. A 40s long hotfire test with 4.95 s on, 50ms off repeated pulses.
PAPERS:
A110 was presented at the 69th JANNAF Propulsion Meeting (June 2022).
