Key Takeaways:
McCauley's C1106 five-blade composite propeller for the Beechcraft Denali has successfully completed key vibration testing, moving it closer to certification.
The prop, designed for the GE Catalyst turboprop engine, underwent strain tests from idle to maximum power, exceeding all specified requirements due to its electronic control system.
This successful testing is a major milestone for the Denali program, which is now targeting certification in the second half of 2024.
The 105-inch diameter propeller features a new forged aluminum hub, electric anti-ice functions, and is targeted for a 6,000-hour or 72-month Time Between Overhauls (TBO).
