Engines on a mission

From corporate to charter operators, from skydiving to medical support and cargo transport, H-Series engine – a product of Avio Aero, a GE Aerospace company – 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, this turboprop engine family’s configuration allows seamless integration into a variety of airframe types.

    Advanced turboprop
    propulsion technology
    The 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.

    Electronic Controls
    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. An Aerobatic version of H-Series engine, with a unique multi attitude lubrification system designed to enable flight with zero gravity and strengthened structure for demanding aerobatic maneuvers is undergoing final development tests.

    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 Aerospace’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.

    When the aerobatic H-Series engine is certified, it will be the first electronic and engine propeller controlled (EEPC) aerobatic engine in its class.

    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 Aerospace’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 Aerospace offers two locations for overhaul: Prague, GE Aerospace’s production site, or Prime Turbines, GE Aerospace’s authorized repair and overhaul center in Texas.
