Raisbeck Propellers Available for All King Airs

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. Propeller blade sweep allows the increase in diameter while simultaneously reducing noise and improving thrust and efficiency. Raisbeck has been delivering swept blades for the King Air 200-series since the beginning of this year.
