The General Electric Catalyst (formerly Advanced Turboprop, or ATP) is a turboprop engine under development by GE Aviation. It was announced on 16 November 2015 and will power the Beechcraft Denali, it first ran on December 22, 2017, and should be certified in 2020. The 850 to 1,600 hp (630 to 1,190 kW) engine aims for 20% better efficiency than its competition thanks to a 16:1 overall pressure ratio, variable stator vanes, cooled turbine blades, 3D printed parts and FADEC.

Beechcraft Denali Completes First Flight Textron Aviation’s Beechcraft Denali turboprop single lifted off on its first flight this morning from Wichita Eisenhower National Airport on a flight over central and southern Kansas that lasted 2 hours and 50 minutes. During the test flight, the clean-sheet airplane reached an altitude of 15,600 feet and a top speed of 180 ktas. The first flight comes after initial runs of the new GE Aviation Catalyst engine on the Denali prototype in late August. The 1,300-shp engine features Fadec and trend monitoring, which will provide on-condition maintenance with no required mid-life hot section inspection.  Originally branded as a Cessna airplane until mid-July, the Denali is equipped with Garmin G3000 touchscreen avionics, including three, 14-inch diagonal, wide-screen LCDs, synthetic vision, ADS-B In/Out and weather avoidance radar. With an expected range of 1,600 nm, a maximum cruise speed of 285 knots, and a full fuel payload of 1,100 pounds, the airplane is configurable for both passenger and cargo missions with its flat floor. It includes a 53-by-59-inch rear cargo door, as well as executive features such as a digital pressurization system that maintains a 6,130-foot cabin to 31,000 feet. Two other flight-test Denalis are in development and three additional ground articles will be used for airframe static and fatigue testing, as well as cabin interior development testing. Denali certification is expected in 2023.
