Raisbeck Touts New Prop Blades for King Air C90

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.

Blade quarter-chord sweep on the King Air 90-series propellers has been increased to 30 degrees at its outer diameter and the diameter has been lengthened by six inches, to 96 inches. These changes are so stark that Raisbeck said the new blades are the “most visible” of the King Air improvements it has done over the past 31 years.
