H80: Advancing a legacy of reliable power for turboprop aircraft

GE is incorporating sophisticated technologies into the H80 to elevate it to even higher levels of performance. Modern 3D aero design and advanced materials have been integrated into the compressor stages and turbine of the engine's gas generator. A blisk design, replacing individually bladed compressor disks, has also been incorporated in the axial compressor stages. Materials with higher temperature capabilities have been introduced into the turbine nozzle guide vanes of both the gas generator and power turbine. These technologies deliver more shaft horsepower, improve engine fuel efficiency and provide increased temperature margin, significantly enhancing hot-day takeoff performance and high-altitude cruise speeds.
