Design and Test of Additively Manufactured Check Valves and Pressurization Diffusers

Abstract—Presented herein are metallic, additively manufactured hydraulic components comprising a set of competing pressurization diffusers as well as a set of competing relief check valves. The diffusers and check valves were grown out of a common material, Inconel 625. Then each set was tested for its cryogenic performance in cryogenic shock, flow testing, and vibration testing. This paper provides supporting evidence that metallic additive manufacturing components can be manufactured for use on launch vehicles, satellites, and re-entry vehicles. These hydraulic components – generalized for use with myriad aerospace, automotive, industrial, and seafaring applications – demonstrate a validation of metallic additive manufacturing as being at the forefront within the realms of both propulsion and materials science engineering.

Index Terms—Additive manufacturing, cryogenics, hydraulics, propulsion, materials, launch vehicles, re-entry, spacecraft, check valves, pressurization diffusers, advanced manufacturing.
