ATEC, February 15, 2017 - The U.S. Army recently designated the ATEC HPW3000 helicopter engine the T900-HPW-900 engine.
The assignment of a customer naming designation is typical as an engine development program matures.
As the ATEC offering for the Army’s Improved Turbine Engine (ITE) program, the T900 employs a state-of-the-art dual spool design that incorporates two rotating turbine-compressor assemblies instead of just one. As a result, the T900 will deliver better dependability, greater fuel efficiency, more power and lower cost over the life of the engine compared to single-spool designs.
The Army intends to downselect to a single design after a Preliminary Design Review (PDR).
The T900 engine is a dual compressor design for Apache and Black Hawk helicopters.
The T900-HPW-900 engine will have an “XT” designation (XT900-HPW-900) until preliminary flight rating (PFR) has been achieved. Once PFR has been achieved, the engine will have a “YT” designation (YT900-HPW-900). The ATEC engine will be given a “T” designation (T900-HPW-900) once full qualification is complete.
