Swept Blade Turbofan




Raisbeck Engineering and Hartzell Propeller have teamed to develop and certify the first business aviation turbine propeller using practical swept-wing theory as an integral part of its design.

The effort has culminated in the FAA certification of the Raisbeck/Hartzell Swept Blade Turbofan Propeller for the King Air 200/B200/B200GT. The new Swept Blade Propeller has been added to Raisbeck Engineering’s Airplane Flight Manuals, making it compatible with all combinations of Raisbeck performance systems for these aircraft, and carrying with it all these systems’ FAA-approved increased performance levels.

If you want the most out of your aircraft, couple the Swept Blade Prop with our EPIC PLATINUM package to create the best performing King Air in the field.
