As the first clean-sheet engine design for the turboprop market in more than 50 years, the Catalyst™ engine ushers in 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 Advanced turboprop engine
The Catalyst™ engine features an industry-best 16:1 overall pressure ratio enabling the engine to achieve as much as 20 percent lower fuel burn and 10 percent higher cruise power compared to competitors in the same size class.
The Catalyst engine - aimed at the 850-1600 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.
Smarter, lighter, cleaner
Catalyst engine is the culmination of our commitment to extensive research and development, and advanced engineering with state-of-the-art technology and additive manufacturing componentry. The engine’s 3D printed parts are both lighter and more durable - ultimately delivering the best power-to-weight ratio in its engine class. This capability also allows for increased range, added payload, and a larger, quieter cabin.
