Mooghas a strong heritage of providing thrusters and associated components to global satellite customers. To prepare for the ever-evolving space market, Mooghas invested in a state-of-the-art metal Additive Manufacturing (AM) facility and a new engine testing facility.

Currently, Moogengineers are developing technologies to support the next generation of monopropellant and bi-propellant small thrusters, utilizing AM and other advanced manufacturing methods. AM offers unique geometries that increase propellant flow efficiencies and provide unparalleled thermal management. Within one-half inch, a thruster could have a surface that will be greater than 2500藲 F and another feature that needs to be maintained to less than 100藲 F. The additive configuration allows for these temperatures to be accommodated where traditional manufacturing methods would not meet the expected package requirements.

When compared to a conventional design method, additive offers the advantages of weight reduction, overall part-count reduction, reduced special processes such as welding and brazing, faster design iteration with shorter lead-times, and improved performance with a potential for lower cost products. Mooghas recently manufactured, and hot-fire tested AM rocket engine injectors made of titanium and INCONEL庐. Traditional or subtractive machined parts have a lead-time of 12-15 months. 黑料社鈥檚 AM rapid product development reduced the lead-time to 4-6 months, with a replacement part lead-time of 4 days. Complex geometry due to injector complexity, envelope, and mass constraints made AM development the answer for a hardware design that had to meet strict customer performance specifications.
