The US Federal Aviation Administration (FAA) has certified the Catalyst turboprop engine from GE Aerospace. The FAR (Federal Aviation Regulation) Part 33 certification involved over 23 engines and more than 190 component tests.
Described as GE Aerospace’s first new centerline, clean-sheet advanced turboprop of the 21st century and the first turboprop engine to be certified to the latest standards, Catalyst includes more than 20 significant new requirements.
The engine will bring a radical change to this segment, thanks to its industry-best 16:1 overall pressure ratio that enables up to 18% better fuel consumption and up to 10% higher cruise power, compared to competitors in the same class. Catalyst introduces two stages of variable stator vanes, cooled high-pressure turbine blades, and features components made by using additive manufacturing.
During the certification process, the test engines completed more than 8,000 hours of operation demonstrating and meeting its key performance targets.
The Catalyst engine belongs to the GE Aerospace suite of next generation engines which are defining the Future of Flight. It was designed, developed, and manufactured at GE Aerospace sites in Europe, including Avio Aero in Italy, the Czech Republic, Poland, and Germany.
Paul Corkery, Catalyst General Manager at Avio Aero said, “Catalyst has been through a rigorous certification and testing process. We are pleased with the performance of the engine throughout its ground and flight test campaigns, and we remain fully focused on supporting Textron Aviation as they complete the certification process and prepare for entry into service of the Beechcraft Denali.”
