The power to explore

The Catalyst engine is the new advanced turboprop heralding a new era in business and general aviation. By utilizing technologies proven on GE’s larger commercial engines over millions of flight hours, it is balancing “all new” with “low risk and high value,” thus advancing airframer, operator, passenger, and pilot experience. The first business and general aviation application for the Catalyst will be introduced on the brand-new Beechcraft Denali.

    Explore the Catalyst engine

    The Catalyst engine features an industry-best 16:1 overall pressure ratio enabling the engine to achieve as much as 18 percent lower fuel burn and 10 percent higher cruise power compared to competitors in the same size class.

    A game changer
    The Catalyst engine - aimed at the 1200-1400 SHP range - is the first modern turboprop ever built with 3D-printed parts, writing a pioneering chapter for the aviation industry. Avio Aero and GE’s engineers incorporated customer feedback into the engine’s design and development, for engineering design flexibility and a more pleasant, quiet, and sustainable journey for pilots and passengers.

    More efficiency, less emissions
    A more fuel efficient, digitally-controlled engine opens a world of opportunities. The Catalyst engine benefits from GE’s engineering expertise and from the largest European research and development programs devoted to decarbonization. Additive technology has been used in combination with advanced alloys to allow more geometrical freedom in the design. The result is reduced fuel burn and weight, and in contrast, increased durability and efficiency.
