The Whirl Wind STOL 200A and 400A constant speed, hydraulically controlled propeller systems are ideal for utility aircraft equipped with the Lycoming IO-320**, -360, -375 or -390 engines (160-240 hp). The 200A is a two-blade propeller systems and the 400A is a three-blade propeller system.
All of these propeller systems consist of carbon fiber blades with 0.025” thick nickel leading edge erosion shields, aluminum hub and a composite spinner assembly. The exceptional integrity of the nickel leading edge makes these propellers perfect for flying in rain or snow, off of unimproved airstrips and water.
The extremely aggressive airfoil of the thin, foam core blade 80” 200A is our most dynamic blade to-date and pulls the hardest of this family, provided enough horsepower is behind it.
Whirl Wind has made significant developments in the construction of the carbon composite propeller blades ensuring extremely strong yet extraordinarily light and durable propeller systems with unlimited life.
