TECH FOCUS: ADDiTivE MANUFACTUriNg The Chinook aircraft remains a key part of enduring heavy-lift fleets around the world. Chinook flies first flight-critical, 3D-printed part on rotorcraft A T408 engine demo proved that the Chinook can leverage more powerful engines. But that wasn't the demo's only achievement, according to the aircraft's manufacturer, Boeing. The company was also able to use its advanced manufacturing expertise by 3D-printing an aluminum, flight-critical part for the effort, the first time that's been done on a rotorcraft. The newly-built transmission housing enabled a critical test effort for the joint 12 July 2022 team, and established a path toward expanded use of additive manufacturing. Boeing is continuing to invest in the future through cutting-edge, additive manufacturing technology to unleash possibilities and accelerate innovation that can drive quality improvements in its products, enhance efficiency and safety in its operations, and enable collaborative AM solutions for customers.
