H-Series Turboprop engine family — Engines on a mission
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 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.
