Key Takeaways:
McCauley's 5-blade composite C1106 propeller, designed for the Beechcraft Denali and its GE Catalyst turboprop engine, successfully completed critical vibration testing.
This achievement marks a significant step towards the Denali's certification, as it's the first composite propeller to be paired with the GE Catalyst engine and features a proprietary electronic control system for optimized performance.
The C1106 propeller targets a 6,000-hour or 72-month Time Between Overhauls (TBO), with the Denali's certification now anticipated in the second half of 2024.
A new prop for a new engine—and airframe—has completed key tests in the ongoing quest towards certification on the Beechcraft Denali.
