74RV Series Propeller

Maximum Performance • Lightest Weight • Best Quality
Quiet and Smooth Operation • Complete Propeller & Spinner Package • Competitive Price

The high performance Whirl Wind 74RV Series non-counterweighted propeller systems incorporate a “scimitar” style swept-tip blade profile and are available in two or three blade configurations. The systems consist of carbon fiber blades with electroformed nickel leading edge erosion shields, CNC machined aerospace grade aluminum hub and a composite spinner assembly.  The 74RV Series propellers have been designed for operation in the rain and snow and are perfectly suited for operations off unimproved airstrips.

The idealized blade shapes of the 74RV Series are possible due to advanced carbon composite structure manufacturing techniques developed by Whirl Wind. This cutting edge process involves overlaying the thermoset carbon fiber composites over a high density foam core. This new technology has yielded a thinner yet very strong blade. The highly tapered swept blade plan form airfoil design has been designed for optimized blade loading distribution resulting in maximum efficiency and minimum noise.

These elements combine to produce the high performance propellers required to meet the demands of today’s high performance airplanes.
