Raisbeck Engineering unveiled this week at NBAA-BACE the Composite 5-Blade Swept Propeller for Beechcraft King Air 200 series aircraft. The propeller was designed by Hartzell Propeller specifically for King Air 200, B200, and B200GT aircraft, and STC’d by Raisbeck Engineering.
According to Raisbeck, the propeller is noticeably quieter with a 30% noise reduction throughout the aircraft and constructed of structural carbon fiber composite with nickel cobalt leading edges to protect against foreign object damage, the Composite 5-Blade Swept Propellers optimize airfoil efficiency allowing for a larger 96-inch diameter propeller with less blade tip noise. This next generation of propellers offers King Air operators an average of 48 pounds total weight savings versus OEM installed propellers, 16.5% performance in runway acceleration, 48% better in prop reverse and 25.8% better in engine-out climb scenarios with flaps up. The propeller also features unlimited blade life, thereby lowering maintenance and overhaul costs.
Hartzell and Raisbeck have a long-standing relationship in developing swept blade technology for the entire King Air line. Hartzell’s recent Type Certification (TC) validation for the Composite 5-Blade Swept Propeller paves the way for Raisbeck to acquire Supplemental Type Certificate (STC) approval from the Federal Aviation Administration (FAA) and begin deliveries in November.
“Raisbeck’s singular focus has always been about performance and added value for aircraft owners,” said company President, Lynn Thomas. “We’re excited to be working with Hartzell to expand our offerings of propellers for the King Air 200 aircraft.”
Raisbeck also offers King Air 200 aircraft owners and operators the option of an Aluminum 4-Blade Swept Propeller, also aerodynamically designed to provide more thrust with less noise. Raisbeck is now taking orders for the Composite 5-Blade Swept Propeller.
