The ITEP is also aligned with the Army’s Operational Power and Energy Strategy efforts, DOD’s Opera- tional Energy Strategy, and the National Defense Strategy.

Named the Advanced Affordable Turbine Engine (AATE) program, the S&T initiative aims to develop an engine that will pro- capability with its 3,000 shaft horsepower. AATE is focused on developing new

TODAY’S ENGINE
The General Electric 701D turbine engine, currently used in the UH-60 Black Hawk and AH-64 Apache helicopters, has 2,000 shaft horsepower. Engines developed through the Improved Turbine Engine Program (ITEP) will provide 3,000 shaft horsepower, with a 25 percent decrease in specific fuel consumption and a 35 percent decrease in production and maintenance costs.

turboshaft engine technologies that will bolster the modernization requirements necessary to ensure that the Apache effective well into the 21st century. The AATE program is also an integral part of
the DOD/NASA/U.S. Department
of Energy Versatile Affordable Advanced Turbine Engine program, which is guid- ing the development of advanced turbine engine technology to support the future operational capabilities of the Nation’s air platforms. Air Force, Navy, and NASA personnel have supported design and test readiness reviews for the AATE program.
THE S&T VISION The concept for the ITEP dates to more than 10 years ago, according to LTC

program began four years ago, and the between the U.S. government and indus- try was signed in 2008.
“Our basic goal was to develop a more powerful 3,000-shaft-horsepower engine - tion, such that if you were to use it at its maximum power design point, it would explained. “At the same time, we wanted to keep the same weight as the current
The ITEP engine is being designed so that the current engine can be removed and replaced without changing any major structural support in the aircraft, while maximizing the footprint of the engine
