Development Of A Regeneratively Cooled Liquid Rocket Engine, Dillon Petty, Nicole Zimmerli
Williams Honors College, Honors Research Projects
An additively manufactured (AM) liquid rocket engine, consisting of an injector, combustion chamber, and nozzle, was designed and printed using state-of-the-art methods and materials. The parts were manufactured using laser powder bed fusion. Additive manufacturing allowed for complex geometries and features, such as printing manifolds onto the components with a reduced number of parts. Additive, regenerative cooling channels were designed into the chamber and nozzle to allow for long-duration steady-state operation.
The feed system for the engine was designed and built to allow for pressure-regulated and steady-state testing. Tanks for the fuel and oxidizer were designed and built for a …
