ATEC Completes T900 Preliminary Design, Submits Phase II OF ITEP EMD Proposal

July 30, 2018

Huntsville, AL, July 30, 2018 – The Advanced Turbine Engine Company (ATEC), a joint venture of Honeywell International Inc. (NYSE: HON) and the Pratt & Whitney Division of United Technologies Corporation (NYSE: UTX), submitted Phase II of its proposal for the Engineering and Manufacturing Development (EMD) phase of the Improved Turbine Engine Program (ITEP) to the U.S. Army Contracting Command, Redstone last week. ITEP is the Army’s #1 aviation modernization priority to develop and field a more powerful, reliable and fuel-efficient engine for Black Hawk and Apache helicopters.

Since the submittal of the Phase I proposal in February 2018, ATEC successfully conducted Preliminary Design Reviews (PDR) that consisted of the engine control system, software, and engine systems. The ATEC team met all entry and exit requirements for the Preliminary Design phase, proving the T900 engine is prepared to move into the EMD phase of the program.

The Phase II proposal consists of a technical volume that details the capabilities of ATEC’s offering for ITEP – the T900 engine. The proposal highlights the many benefits of the dual-spool T900 engine.

The new ITEP engine must be 50 percent more powerful, 20 to 25 percent more fuel efficient, and provide a 20 percent longer design life over the current engine, while also maintaining high levels of performance at 6,000 feet and 95 degrees Fahrenheit. This allows the aircraft to travel longer distances with heavier payloads, while reducing and eliminating dangerous refueling stops in the middle of a mission.

“The T900 state-of-the-art engine will save an additional 3 to 4 percent in mission fuel burn compared to a comparable single-spool engine,” said Jerry Wheeler, vice president of ATEC. “The T900 will also have a world class engine control system that benefits from the most technologically advanced control systems used in the F-22 and F-35 fifth generation fighter aircraft. The lower inertia of the high-pressure system results in faster response to a pilot’s command for a change in power and in more rapid engine starts. Additionally, the T900 architecture provides superior power growth capability for the future, allowing ATEC to meet the Army’s power needs for these and future aircraft.”

“Army Aviators are going to love this engine,” said Craig Madden, president of ATEC and a former Army aviator. “What this means is that this engine will provide superior system responsiveness to pilot commands, resulting in immediate and precise power setting changes and ease of operation. This will reduce pilot workload and allow aviators to focus on the mission, not the aircraft. ATEC’s T900 architecture meets or exceeds Army requirements using current, state-of-the-art materials, without the pilot or maintainer having to be concerned about unproven materials that are not yet ready for production and field use.”

“For the Army maintainers, the T900 will offer many advantages over the current engine,” said Mike Doyle, director of logistics for ATEC and former U.S. Air Force Chief Master Sergeant. “Leveraging ATEC’s strong and diverse portfolio of member company engines, the T900 provides next-generation modular design with four completely independent and self-contained modules enabling easy removal and simplified maintenance tasks. The T900 will significantly reduce the required logistics footprint supporting the expeditionary forces of Army aviation. Building off a combined 160+ years of Army aviation experience, the T900 provides simpler maintenance procedures and more flexibility for commanders in the field. The T900’s dual-spool architecture also enables it to operate at cooler temperatures with less stress, which improves reliability.”

“We have demonstrated in our PDR as well as our Phase I and Phase II proposals that ATEC has the most advanced, the most capable, and the lowest risk engine for Black Hawk and Apache helicopters,” said Wheeler. “The dual-spool engine architecture of the T900 offers superior performance, reliability, and growth relative to a comparable single-spool engine. It also offers several advantages for Future Vertical Lift Capability Set I aircraft. We stand ready to partner with the Army to provide and support an engine that meets the needs of Army Aviation for the next 50 years.”

The Army plans to review the proposal for the remainder of the year and then award a single contract for EMD in the first quarter of 2019, with final design and extensive ground/flight testing leading to engine qualification and low-rate production in 2024.

“As a former Combat Aviation Brigade (CAB) Commander, as well as Black Hawk and Apache pilot, I can attest to how committed the ATEC team is to making the best possible engine for the warfighter,” said Madden. “From our corporate CEOs’ commitment to our engineering expertise, the U.S. Army can count on ATEC to field an engine that will meet or exceed all Improved Turbine Engine Program requirements.”

ATEC brings together the world-class engineering, production and manufacturing capabilities of two industry-leading companies – Honeywell and Pratt & Whitney – to build the advanced and fuel-efficient 3,000 shaft horsepower turbine engine. It is the only company with the singular focus of delivering the best engines for the Army with the lowest risk.
