The performance our warfighters deserve. The value our taxpayers demand.

SUPERIORITY THROUGH
PERFORMANCE: T900

ATEC VALIDATES INSTALLATION CAPABILITY OF T900 IMPROVED TURBINE ENGINE ON BLACK HAWK AND APACHE READ MORE

The Improved Turbine Engine Program (ITEP) is the U.S. Army’s initiative to develop a new engine to power its Black Hawk and Apache fleets.

WHY WE NEED A NEW ENGINE

RIGHT NOW, OUR WARFIGHTERS FLY INTO BATTLE ABOARD BLACK HAWK AND APACHE HELICOPTERS THAT ARE UNDERPOWERED IN HIGH AND HOT CONDITIONS, AND THAT USE TOO MUCH FUEL.

engine life

The new engine must be 50% more powerful, 25% more fuel efficient, and provide 20% longer engine life over the current engine, while also meeting stringent performance goals in high and hot conditions at 6,000 feet and 95 degrees.

More Power to Grow

Better Dependability

ATEC’S T900
DUAL-SPOOL ENGINE:
THE SUPERIOR CHOICE

MORE POWER

The T900 dual-spool engine has 10 percent more power growth capability than comparable single-spool offerings, giving the Army more flexibility as mission requirements evolve and change.

Dual-spool engines help save more lives and protect our troops. Dual-spool means an engine has two rotating turbine-compressor assemblies instead of just one. The use of two spools delivers better dependability, greater fuel efficiency, more power to grow and lower cost over the life of the engine compared to single-spool designs currently in use.

GREATER FUEL EFFICIENCY

Because it can run its two compressors at different speeds – optimizing engine operation – a dual-spool engine achieves greater fuel efficiency than a single-spool design. The T900 not only will meet the Army’s requirement for greater fuel efficiency over the current engine, it will provide a 3-4 percent specific fuel consumption advantage over comparable single-spool offerings.

BETTER DEPENDABILITY

A dual spool engine automatically distributes load between two compressors and constantly adjusts load born by each to optimize performance. This allows the engine to run cooler, reducing wear and tear. In sandy conditions, for example, the rear compressor can turn faster allowing the front compressor to turn more slowly, improving performance and allowing the front compressor to take less of a beating from sand ingestion.

LOWER COST OVER THE LIFE OF THE ENGINE

Dual-spool engine architecture allows the T900 to run cooler and more efficiently. This reduces wear-and-tear, decreases associated maintenance costs and extends engine life. The T900 offers the Army lower total cost over the life of the engine. Compared to the current single-spool engine, the T900 will save the Army a billion dollars a year after being fielded.

Greater Fuel Efficiency

Lower Cost Over the Life of the Engine

ATEC

A JOINT VENTURE OF HONEYWELL AND
PRATT & WHITNEY

In 2006, Honeywell and Pratt & Whitney joined together specifically to develop an advanced turboshaft helicopter engine that achieves the aggressive performance goals set by the U.S. Army: a 50% more powerful and 25% more fuel-efficient engine for the Black Hawk and Apache fleets. The dual-spool T900 engine developed by ATEC will meet or exceed every performance standard set by the Army. ATEC supports U.S. jobs in engineering, supply chain, manufacturing and logistics. Honeywell and Pratt & Whitney have decades of experience powering commercial and military aircraft – including helicopters, cargo planes, tankers, trainers and fighters. ATEC combines the best technology and experience of these two industry leaders to produce the T900.
