H-Series Turboprop engine family — Engines on a mission

h series turboprop engine family

The ideal, reliable power for turboprop aircraft

From corporate to charter operators, from skydiving to medical support and cargo transport, GE’s H-Series engine is renowned for its reliability. The H-Series thrives in rugged conditions that require mission readiness, short takeoffs, weight variability and safe operation: in the hottest deserts, over the highest peaks and across the most remote archipelagos. Available in a range from 550 to 850 SHP and in an aerobatic version, this turboprop engine family’s configuration allows seamless integration into a variety of airframe types.




Advanced turboprop propulsion technology

GE’s H-Series engine is a two-shaft, reverse flow engine with a free turbine, available with first-in-class Electronic Engine and Propeller Control (EEPC). The engine has an axial compressor and compressor turbine featuring 3D geometry design. Fuel is distributed to the chamber via the slinger ring combustor architecture, which simplifies maintenance and eliminates the need for recurrent fuel nozzle inspections. The propulsion section is powered by a single-stage turbine driving a two-stage planetary gearbox.





A Jet-like experience

The EEPC system, featuring fully integrated engine and propeller operations, provides safer operation and reduces pilot workload by simplifying engine operation with a single lever power control, that enhances enhancing engine operability. The Aerobatic version of GE's H-Series engine is also equipped with a unique multi altitude lubrification system, designed to enable flight with zero gravity and strengthened structure for demanding aerobatic maneuvers.

Maintenance Simplicity

From a pilot’s reduced workload in the cockpit to reduced engine noise in the cabin and industry-leading predictive engine analytics, Airframers, passengers, and crew fly with confidence.

GE’s reliability and infused technology mean airlines and charter operators can fly on time and avoid maintenance that may otherwise take engines out of service. H-Series engines have no fuel nozzles and no hot section inspections, easing the burden of additional maintenance.

H-Series service centers

The H-Series engine’s unique design provides more than just performance. With no fuel nozzles, it requires no hot section inspection and minimal maintenance between overhauls. This means operators can devote more time to their missions in the air. When customers do need assistance, GE’s field service and customer support teams are available 24/7 and are backed by a global network of 22 authorized service centers across 12 countries, making repairs local and expedient. GE offers two locations for overhaul: Prague, GE’s production site, or Prime Turbines, GE’s authorized repair and overhaul center in Texas.
