PDR of T901-GE-900 engine complete
GE Aviation and the US Army have conducted the Preliminary Design Review (PDR) of the T901-GE-900 engine, the company announced on 25 April.
The engine is being developed for the US Army’s Improved Turbine Engine Programme (ITEP), under which it will re-engine its AH-64 Apache and UH-60 Black Hawk helicopters.
The PDR is a milestone within the GE's Technology Maturation and Risk Reduction (TMRR) contract. The army will down-select to one engine manufacturer for the Engineering and Manufacturing Development (EMD) phase by the end of 2018.
GE Aviation submitted the first phase of its proposal in February, and is now preparing the second and final phase based on the engine configuration reviewed at the PDR.
The company successfully completed a fit test with the army in December 2017 by using a full-scale engine mock-up, demonstrating seamless integration of the T901 with the Apache and Black Hawk airframes.
Ron Hutter, executive director of the T901 program, said: ‘The simple, proven, single-spool design of the T901, coupled with GE’s advanced commercial and military technologies, allow it to exceed the army’s requirements. The T901 is lighter, less complex and more maintainable for the warfighter, which leads to improved readiness and reduced life-cycle costs.’
