GA200L-78 S.T.O.L propeller
LYCOMING 0-320/ IO-360 ENGINES
The GA200L-78 propeller was designed for short take off and landing (STOL) aircraft powered by Lycoming 0-320 / 0340 / 0360 engines (150-180hp). This propeller is the perfect upgrade for experimental Super Cub type aircraft.
GA200L-78 (2-blade) for STOL style aircraft
The GA200L-78 STOL propeller allows you to adjust the propeller pitch to your preferred mission profile (aggressive short field and climb, or for quiet, efficient cruise performance or some where in-between). You have multiple mission settings all in one propeller. Efficient operation and high performance goals were in mind when we designed the long highly tapered blade shape and very thin blade cross-section along with the aggressive under cambered airfoils to achieve optimum lift distribution and maximum L/D.
GA200L-78 STOL Blades:
The blades of the GA200L-78 STOL propeller are manufactured with thermo-set carbon fiber composites, overlaid on a high density foam core. The GA200L-78 features composite blades with highly tapered, swept blade planform and propriety airfoils. The blades have been designed for optimized blade loading distribution resulting in maximum efficiency and minimum noise. The idealized blade shape of the GA200L-78 is made possible with advanced carbon composite structure manufacturing. The leading edge protection is electroformed nickel which offers the best abrasion protection, especially when flying from unimproved airstrips. The blades are painted satin black with white tip striping and are finished with a durable polyurethane top coat.
GA200L Hub:
The GA200L hub assembly is 3-D CNC machined from aerospace billet aluminum and is dimensionally certified. Each hub is anodized black for corrosion resistance and appearance.
Pitch Change:
The key feature of the GA200L-78 STOL propeller is that blade angles can be adjusted to an infinite number of settings. Propeller blade pitch change is a breeze. It’s a three-step process. 1. Loosen the hub clamp bolts, 2. Rotate the blade via supplied blade pitch paddle to desired pitch setting and verified by digital protractor (not supplied). 3. Tighten and torque hub clamp bolts. The process takes about ten minutes including removing and installing the spinner dome.
The highly tapered, swept blade planform and propriety airfoils is designed for optimized blade loading distribution resulting in maximum efficiency and minimum noise. The Idealized blade shape is made only made possible with advanced carbon composite structure. WhirlWind propellers come standard with electroformed Nickel leading edge shields for superior fit and abrasion protection and Polyeuathane top coat. The hub is CNC machined from aerospace aluminum and is dimensionally certified.
