Whirl Wind is excited to introduce our newest design, the 300 Series propeller.
The 300 Series is an entirely new three blade propeller platform designed specifically for four cylinder aircraft engines ranging from 160 to 220 horsepower. Whirl Wind incorporated advanced engineering tools in the development of the 300 Series, including exclusive use of full solid modeling including animation, high end finite element analysis and extensive vibratory studies on a wide range of engines, including the IO-320, -360, -375 and -390 engines. The 300 Series has endured more design scrutiny and study than any other prior Whirl Wind design.
The 300 Series development has taken several years. Initial test performance results have been very good. Pilots have noted increased take off acceleration and an increased rate-of-climb with the same top speed as Whirl Wind's legendary 200RV Series™ propeller.
At only 36 pounds (including the composite spinner) this 72" diameter propeller is the lightest weight constant speed propeller in its class. Most impressive is that it is a three blade propeller that is 5 pounds lighter than Whirl Wind's two blade 200RV Series propeller due to the 300 Series' optimized, compact design.
In addition to weight savings the 300-72 composite propeller offers ultra-smooth operation and lower cockpit noise levels. The 300-72's proprietary blade design features a patented carbon fiber X-core™ thermoset composite construction with an electroformed nickel leading edge for superior erosion resistance and FOD protection.
