Huntsville, Ala., April. 27, 2018 – The Advanced Turbine Engine Company (ATEC), a joint venture between Honeywell International Inc. (NYSE: HON) and the Pratt & Whitney Division of United Technologies Corporation (NYSE: UTX), successfully conducted the Preliminary Design Review (PDR) toward the development of the Army’s most advanced helicopter engine earlier this month.
As part of the U.S. Army’s Improved Turbine Engine Program (ITEP), ATEC conducted a rigorous PDR with the Army for its T900 engine. ITEP is the Army’s program to develop and field a replacement engine for the service’s Black Hawk and Apache helicopters. The PDR involved ATEC briefing high-level Army leaders on the advantages of the T900 over the current engine in Black Hawks and Apaches and other offerings for ITEP.
“The successful PDR underscores that the ATEC team continues to develop an engine that will meet the Army’s aviation needs well into the future,” said Craig Madden, president of ATEC. “It also is an endorsement of our proven and state-of-the-art dual-spool architecture combined with an advanced control system that will deliver increased performance and durability to warfighters in challenging environments, when they need it most.”
The PDR is an important technical assessment that ensures the engine is operationally effective. It allows the Army an up-close examination of the T900, its hardware and software. The success of this milestone allows ATEC to transition to the next phase of ITEP, a final submission of technical volumes over the summer.
ITEP seeks to develop an engine that generates 50 percent more power, is 20-25 percent more fuel efficient and has a 20 percent increase in design life relative to the current engines in Black Hawks and Apaches.
The ATEC joint venture brings together the world-class engineering, production and manufacturing capabilities of two industry-leading companies to build the advanced and fuel-efficient 3,000 shaft horsepower turbine engine.
The major technical advantage of the T900 engine is its dual-spool architecture. The term “dual-spool” refers to the number of rotating assemblies within the helicopter engine. A proven and standard feature of engines powering fixed-wing propeller and jet aircraft, each spool is comprised of a turbine‐compressor combination. The dual-spool architecture excels in several areas, including power, performance, reliability, fuel efficiency and life cycle cost savings.
