GE completes T901 turboshaft engine prototype testing
The engine was manufactured using 3D printing technology
The T901 is designed using GE's industry-leading 3D aerodynamics design tools validated in the Advanced Affordable Turbine Engine (AATE), Future Affordable Turbine Engine (FATE), and Improved Turbine Engine Program (ITEP) prototype engine programs. This design practice leads to:
The T901's use of CMCs enable the engine to produce more power with less weight. Higher temperature capability means more engine airflow can go towards powering the helicopter.
The T901 directly benefits from GE's industry-leading additive manufacturing capabilities. This technology enables game changing system solutions which result in improved performance with significantly fewer parts, maximizing reliability while reducing weight and cost.
T901 Part vs Comparable T700 Part
GE's next generation of engine cooling capabilities maximize the T901's performance. These technologies reduce allow the T901 to reduce the amount of cooling air required to maintain the same engine temperature, delivering more power and significantly improved fuel efficiency. The results:
The Army's Apaches and Black Hawks operate in the world's harshest conditions. For nearly 40 years GE engines have been there keeping them in the fight. Five million hours of desert operations experience has influenced the T901 Inlet Particle Separator (IPS), allowing the U.S. Army to fly with confidence in tomorrow's severe conditions. The new IPS reduces sand ingestion and pressure loss, decreases wear on turbomachinery components, and provides significant time-on-wing improvement.
The T901 includes multiple sand-tolerant design features, including:
Fix forward design
On the front lines, things do not always go as planned and getting back in the fight quickly is critical. The simple, modular design of the T901 allows maintainers to disassemble, clean or repair, and reassemble the engine in the field, all with only light weight spare modules, without the need to carry the full weight of a spare engine. This means less dependency on combat supply chains, rapid recovery of degraded performance, and less enemy exposure to support elements. GE and the T901 fix forward design keeps you in the fight!
Benefits of a fully modular engine:
Seamless aircraft integration
GE's experience with Apache and Black Hawk engine integration is unsurpassed. GE's expertise and established infrastructure means lower risks to the U.S. Army and seamless integration of the T901.

Benefits of a fully modular engine:
- Flexibility: Fix in the field or at the depot
- Mobility: Only carry small, lightweight modules
- Affordability: Reduces costly depot visits
- Performance Retention: Turbine cleaning possible
- EHM System (CBM+): More EHMS identified faults field repairable
- Commonality with existing Army infrastructure
- Simplified future module and component upgrades
Seamless aircraft integration
GE's experience with Apache and Black Hawk engine integration is unsurpassed. GE's expertise and established infrastructure means lower risks to the U.S. Army and seamless integration of the T901.
- 100% growth within same engine physical interfaces over 6 different T700 models on Apache and Black Hawk
- Intimate knowledge of Apache and Black Hawk systems and functions
- GE experience translates into a seamless integration with lower aircraft program risk
