The HPW3000 is dual-spool engine developed by ATEC as a replacement for present engines in the U.S. Army's Black Hawk and Apache helicopter fleet. The joint venture is designing a 3,000-shaft horsepower engine to replace the current, 2,000-shaft horsepower T700 engine.

ATEC Picked to Develop New Army Helicopter Engines

The Advanced Turbine Engine Company (ATEC, a joint venture of Honeywell (IW500/30) and Pratt & Whitney) drew a new U.S. Army contract to develop and demonstrate advanced engine capabilities for future vertical-lift combat helicopters. The contract is part of the Army's Alternate Concept Engine program, which is seeking significant improvements in future helicopters’ vertical lift, range, speed, payload, survivability, and reliability.

The program also seeks to reduce operational and life cycle costs, and the logistical footprint for both the engine and future combat helicopters.

The terms of the new contract were not announced.

ATEC reported it would demonstrate advanced variable speed turbine capabilities and other new technologies in a demonstrator engine test.
