GE Aviations 3D printed T901 engine increases Black Hawk helicopter range by 161%

GE Aviation has completed testing on its T901-GE-900 turboshaft engine prototype, made for the U.S. Army’s Improved Turbine Engine Program (ITEP) for Apache and Black Hawk helicopters. 3D printing was used to make components of the T901-GE-900 with “more advanced aerodynamic shapes.”
