Hartzell Propeller Inc. and Raisbeck Engineering recently debuted a 5-blade composite swept prop, designed and manufactured by Hartzell specifically for the King Air 200, B200 and B200GT aircraft and STC’d and distributed by Raisbeck Engineering.
This new propeller system is the first five-blade structural composite propeller certified on the King Air 200 series and is said to increases performance across the board delivering more than 15 percent greater takeoff acceleration, over 10 percent better climb rate and five- to seven-knots faster cruise performance compared to original equipment propellers.
Constructed of structural carbon fiber composite with nickel cobalt leading edges to protect against foreign object damage, the new composite five-blade swept propellers optimize airfoil efficiency allowing for a larger 96-inch diameter propeller with less blade tip noise and providing a noticeably quieter cabin – a 30% noise reduction. This next generation of propellers offers King Air operators an average of 48 pounds total weight savings versus OEM-installed propellers. The propeller also features unlimited blade life, thereby lowering maintenance and overhaul costs.
King Air 200 series owners and operators are encouraged to contact Raisbeck or a Raisbeck authorized dealer for more information and pricing.
