Raisbeck Engineering (Booth No. C7326) is highlighting its new swept-blade propellers for all King Air C90-series turboprop twins here at NBAA 2013. Deliveries of the blades, which sweep on both the leading and trailing edges, will begin in January. Raisbeck has been delivering swept blades for the King Air 200 series since the beginning of this year.

Raisbeck Engineering is now offering its swept-blade propellers for all King Air C90-series turboprop twins. Deliveries of the new blades, which sweep on both the leading and trailing edges, will begin in January. Blade quarter-chord sweep has been increased to 30 degrees at its outer diameter, and the propeller diameter has been lengthened by six inches, to 96 inches.
Raisbeck Engineering has come to LABACE to show off its new swept-blade turbofan propellers for the Beechcraft King Air 200 family. The new propellers received certification from the Brazilian civil aviation authorities in June and last month the European Aviation Safety Agency granted its approval as well.
Raisbeck Engineering’s swept-blade propellers for 200-series King Airs have been certified by the EASA, adding to a previous FAA approval. Thanks to a higher blade sweep and increased propeller diameter, the new propellers provide for quieter operation and increased thrust, according to Raisbeck. They provide more than 1,090-feet improvement in published FAA takeoff performance compared with the OEM propellers, Raisbeck said. Deliveries of production swept-blade propellers began in the U.S. in March.
Three aircraft modification specialists with major markets in Latin America, and in particular in Brazil, have joined forces at the LABACE show with a one-stop-shop exhibit (Stand 5005) featuring performance-enhancing technologies. In many ways, the products offered by Blackhawk Modifications, BLR Aerospace and Raisbeck Engineering complement one another, and combined may result in even better performance results, according to the U.S. companies.
Raisbeck Engineering’s swept-blade “turbofan propellers” for the King Air 200 series are now approved in Brazil after the Brazilian National Civil Aviation Agency (ANAC) granted certification late last month.
A spokesperson for Raisbeck Engineering told AIN, “There are about 500 King Airs in Brazil alone, making it a major market for us. We hope that the swept-blade prop reenergizes our presence in the South American region and we’ll be focusing a lot of our attention on the market as it continues to grow.”
Seattle-based performance modification specialist Raisbeck Engineering and Hartzell Propeller have unveiled a new swept-blade propeller for the Hawker Beechcraft King Air series. The newly certified propeller is the result of three years of development, according to the companies, which describe it as the first business aviation turbine propeller using practical swept-wing theory as an integral part of its design. The propellers have aluminum blades and hubs.
