The Southeast Regional Upkeep Middle (SERMC) has efficiently used 3D printing to fabricate a alternative cooling rotor for an Arleigh Burke-class guided missile destroyer’s chilled water pump. The six-blade element will not be offered individually via the Navy provide system, usually requiring the acquisition of a whole new pump unit.
The SERMC workforce developed 4 prototypes over two weeks utilizing reverse engineering methods. They started with a low-cost polymer model of the unique aluminum half earlier than coordinating with Fleet Readiness Middle Southeast Detachment Mayport to pick out the ultimate materials. The completed element was manufactured utilizing an aerospace-grade thermoplastic identified for energy, warmth resistance, and flame retardancy.
The fee distinction between 3D printing and traditional alternative proved important. A prototype blade price $17.63 to provide, whereas the ultimate blade price $131.21. Changing your entire motor via conventional procurement would have price $316,544.16.
“Sailors at SERMC are all the time searching for new purposes for 3D printing to broaden our capabilities and save time, assets, and cash,” stated Capt. Kiah Rahming, SERMC’s commanding officer. “This effort is a testomony to the ingenuity and drive of our workforce.” The printed element has been operationally examined, licensed, and put in aboard a destroyer. These cooling pump rotors are used throughout all ship varieties within the Navy fleet.
