It is common knowledge in the space industry that Moog has been a market leader in the field of in-space propulsion.  For years Moog has provided thrusters, feed systems and components, and tanks to the leading satellite providers around the globe.  Moog has also been adding a lot of internal investment for the future of in-space propulsion.  With a new engine testing facility in the works, a brand new state of the art metal additive manufacturing facility installed and cutting edge development of green propellant thrusters, Moog is prepared to meet the demands of evolving space markets. 

Metal additive manufacturing has many advantages for in-space propulsion; offering lower part counts, reduce lead-times, reduced weights, and unique and improved geometries to increase engine efficiencies.  Moog has been developing processes to develop high temperature tolerant metal materials to use the advantages of additive manufacturing for its small, high performance, high temperature thrusters.  What Moog is discovering with the use of these new additive manufactured engine parts combined with green propellants, is something ground breaking for the in-space propulsion world.   

At the moment, there are three engine sizes utilizing AF315E propellant in testing at Moog: 5 lbF, 40 lbF, 100 lbF.  Moog is seeing ISP levels higher than traditional chemical propellants with our new additive manufactured thrusters and processes.  The injector and nozzles are additively manufactured components and utilizes titanium and Inconel metals.  With temperatures exceeding 2000o F, the results are exceeding expectations of engineers and the customer.  In the future Moog expects these engines will replace traditional chemical in-space engines because they will have higher performance, lower weight, safer propellant handling as just some of the advantages to the customer.
