GE Aerospace has announced the successful completion of initial ground runs for the T901 engine on a U.S. Army Black Hawk helicopter at Sikorsky’s West Palm Beach facility. This milestone marks a key advancement in the improved turbine engine programme’s Black Hawk testing.
The ground runs validated the performance of all critical systems, including fuel, electrical, hydraulic, engine, and flight control systems, as well as engine bay airflow. Additionally, data collected from extensive aircraft and engine instrumentation will support the upcoming flight test programme.
Factory testing continues alongside this integration effort, with data confirming that the T901 engine remains on course to meet the U.S. Army’s stringent performance requirements.
The T901 engine builds on GE Aerospace’s extensive legacy of powering Black Hawk and Apache helicopters with the combat-proven T700 engine, which has accumulated over 100 million flight hours in the past four decades. Developed to meet the Army’s need for greater power and fuel efficiency, the T901 delivers 50% more power, improved fuel economy, and reduced lifecycle costs due to its simpler design and fewer components. This enhanced efficiency translates into greater range, longer loiter time, and lower maintenance and sustainment costs for the Army’s fleet.
The T901 is a cornerstone of the Army’s modernisation efforts, and this milestone highlights GE Aerospace’s commitment to delivering advanced propulsion technology for the missions of the future.
