BLR Aerospace recently announced that their winglet system for the King Air E90 and early C90 fleets, as well as the 5-bladed Whisper Prop® system for the King Air 100, are all scheduled to be Federal Aviation Administration (FAA) certified by the end of 2021. Increasing demand has created limited availability for both popular upgrades so the company encourages those interested to contact them or one of its authorized dealers regarding availability.
The modern BLR/MT 5-bladed Whisper Prop is constructed with a highly engineered structural resin-infused wood core that is wrapped in carbon-fiberglass skins. Each blade is finished with a nickel-cobalt leading edge providing three times more damage resistance than aluminum. BLR says the Whisper Prop has the smallest diameter, is the quietest and most cutting-edge composite propeller on the market. The short diameter protects the aircraft from foreign object damage (FOD) occurrence where the nickel-cobalt leading edge drastically reduces damage and blade erosion. The highly engineered wood core eliminates vibration by more than 50% and decreases the overall wear and cost of operation, including repairs, compared to the foam core composite propeller that comes standard on the aircraft. The Whisper Prop delivers unlimited blade life, field repairable and replaceable blades allowing for superior return to service capabilities and best overhaul schedule. Additionally, it improves takeoff performance by 4.3%, has lower Vmca, has no ground RPM limitation and requires no FAA imposed regular inspections.
BLR’s winglet system is an aluminum wing tip, carbon fiber winglet with integrated position, recognition and strobe LED lighting. The company says it increases overall wingspan and wing aspect ratio to reduce induced drag for faster flight on less fuel as well as improved handling qualities.
