Honeywell and Pratt & Whitney’s joint venture, Advanced Turbine Engine Company (ATEC), has confirmed its T900 can be installed on the Sikorsky Black Hawk and Boeing Apache. ATEC said recently it completed the installation of a high-fidelity mockup of the turbine engine.

ATEC said the installation occurred in the left and right engine bays of the helicopters. The T900 is ATEC’s offering for the U.S. Army’s Improved Turbine Engine Program (ITEP). The program’s goal is to develop a more powerful and efficient replacement for the current engine powering these two platforms. ATEC said the T900 could be installed and removed quicker than the current engine.


“The successful installation of this mockup engine into these two helicopters validates the substantial progress and efforts ATEC, the aircraft manufacturers, and the Army have completed over the past decade,” said Jerry Wheeler, VP for ATEC. “Developing an engine that produces 50% more power, is 20-25 percent more fuel efficient, and fits within the existing bay of the Black Hawk and Apache is an exciting technical challenge. This successful, first-time engine installation is a true validation that ATEC is ready to meet that challenge and that the T900 engine is the right choice for the Army in providing improved mission capabilities to our warfighters.”

The first two demonstrator engines in the Advanced Affordable Turning Engine program were tested in late 2014. Since then, ATEC said it has reduced risk for the T900 engine by doing component rig tests. Additional tests help ATEC improve engine performance while providing further validation of the T900 dual-spool engine architecture, the company said. Preliminary design of the T900 started in August 2016 during technology maturation and risk reduction (TMRR) phase of the ITEP program. Next step is the preliminary design review of the T900 engine with the Army, expected in March 2018.
