Key Takeaways:
McCauley's C1106 five-blade composite propeller successfully completed crucial vibration testing with the GE Catalyst turboprop engine, a significant step towards certifying the Beechcraft Denali.
The propeller exceeded all strain test requirements from idle to maximum power, integrating with the Catalyst engine's proprietary electronic control system for optimized performance.
This milestone advances the Denali's development, with aircraft certification now anticipated in the second half of 2024, and the propeller targeting a 6,000-hour or 72-month time between overhauls (TBO).
A new prop for a new engine—and airframe—has completed key tests in the ongoing quest towards certification on the Beechcraft Denali.
McCauley, a division of Textron Aviation, announced on its social media channels Wednesday that the C1106 prop completed vibration testing married to the GE Catalyst turboprop powerplant expected to drive the Denali.
