Huntsville, Ala., Feb. 14, 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), submitted the first of two proposals to the United States Army Contracting Command for the Engineering and Manufacturing Development (EMD) phase of the Improved Turbine Engine Program (ITEP). ITEP is the Army’s initiative to develop a more powerful, dependable and fuel-efficient engine for Black Hawk and Apache helicopters.
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.
“We are very pleased to offer the T900 dual-spool engine as the best option for the Army’s Improved Turbine Engine Program,” said Craig Madden, president of ATEC. “Our joint venture has spent nearly 12 years developing technologies and designing an engine that will provide expanded mission capabilities to our warfighters. Our proposal lays out why the T900 is the best choice for the Army to improve the overall performance of their Apache and Black Hawk fleets.”
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 Technology Maturation and Risk Reduction (TMRR) phase of the ITE program enabled ATEC to further mature the T900 engine design, building on the very successful Advanced Affordable Turbine Engine (AATE) science and technology demonstrator program. During the AATE program, ATEC conducted several successful rig and demonstrator engine tests in the 2012-2015 timeframe. As part of the TMRR contract, ATEC will soon host a Preliminary Design Review (PDR) of the T900 engine design with the Army and submit the second phase of the ITEP EMD proposal.
The major technical advantage of the ATEC engine over its competitors is that the T900 incorporates 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 since the 1950s, each spool is comprised of a turbine‐compressor combination. The dual-spool architecture excels in several areas, including performance, reliability and fuel efficiency.
