The Advanced Affordable Turbine Engine (AATE) program is a United States Army project to develop an improved engine for use in many Army helicopters.

Program history

Advanced Affordable Turbine Engine (AATE) program is a project of the U.S. Army's Aviation Applied Technology Directorate. The AATE program is under the larger research and development umbrella of the Versatile Affordable Advanced Turbine Engines (VAATE) program. AATE's objective is to develop technologies for a 3,000 shaft horsepower engine that reduces specific fuel consumption by 25%, improves shaft horsepower to weight ratio by 65%, improves design life by 20%, reduces production and maintenance cost by 35%, and reduces development cost by 15% all from year 2000 fielded engine levels.[1] The program began in 2006.

In July 2009, the U.S. Army released a request for information signaling a new program, the Improved Turbine Engine Program (ITEP). This solicitation is the first step in developing an engine that that uses the advancements and research the AATE program started. The engine developed for ITEP is to be a drop-in replacement for the General Electric T700 engine that currently powers the AH-64 Apache and the UH-60 Black Hawk.[1] The program seeks to realize the goals set by the AATE program, as well as meet more specific goals, such as improving lift capability for the AH-64 and the UH-60 in hot climates and high altitudes as well as increasing aircraft mission radius by as much as 500 km.[2]

Both GE Aviation and the Advanced Turbine Engine Company (ATEC) are developing engines for this program, the GE3000 and the HPW3000 respectively.[3] ATEC is a 50/50 joint venture created in 2007 between Honeywell Aerospace and Pratt & Whitney Military Engines.

While little information has been released as of September 2009 about either engine, the HPW3000 has been reported to be a two-spool engine that can start with or without an auxiliary power unit (APU). The GE3000 engine is also reported to have the ability to perform an APU-less start.[4]

ATEC expects to begin full engine testing by 2011.[5]
