Aerojet Rocketdyne has completedÂ a series of hot fire tests on its liquid-fueled rocket engine that was built throughÂ additive manufacturing or 3D printing.
The company said Monday the activity was funded by the Defense Advanced Research Projects Agency and involved 17 tests thatÂ validated theÂ BantamÂ rocket engine’s performance, durability and reusability.
Bantam isÂ aÂ 30,000 pound-force thrust-class engine that is comprised ofÂ three additively manufactured major components including the injector assembly, combustion chamber and a throat and nozzle section, Aerojet Rocketdyne added.
The 3D-printed engineÂ was designed, fabricated and tested withinÂ seven months atÂ a lower productionÂ cost thanÂ engines built using traditional fabrication processes, the companyÂ noted.
Bantam is designed toÂ address the needs of theÂ small launch vehicle and low-cost upper stage markets.
The series of tests builds on Aerojet Rocketdyne’s plans to develop a family of low-cost rocket engines for booster, upper-stage and in-space propulsion platforms.
