The high speed, high performance Whirl Wind HRT Series non-counterweighted propeller systems incorporate a "scimitar" style swept-tip blade profile with a wider tip than our 74RV Series 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 HRT Series propellers have been designed for operation in the rain and snow and are perfectly suited for operations off unimproved airstrips.
The advanced blade shapes of the HRT 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 slightly broader swept tip blade plan form airfoil design has been designed for optimized blade loading on high speed platforms.
Beta tested at the 2016 and 2017 Reno Air Races, these exciting new Whirl Wind propeller systems have raised the bar of performance in our industry.
