Without a method of converting the power produced by the engine into useful thrust an aircraft would just be sitting still and creating a lot of noise and not get anywhere. In the past, all kinds of different propeller designs were tried: sometimes flat wooden blades, from one bladed counter weighted to multiple blade models rotating at various speeds.
Variable pitch propellers have a distinct advantage compared to fixed pitch models. This translates into a more fuel efficient, higher performing aircraft with much improved rate of climb and shorter takeoffs for those tight places!
Performance Propellers USA is built on unsurpassed quality and craftsmanship that is seen on the ground and felt in the air. Whether for a low and slow cruiser or a high power aerobatic machine, each Performance Propeller is fine tuned to meet your specific needs.
Performance Propellers originated in 1988 with Clark Lydick. He since produced over 2000 custom propellers and has passed along his "secrets" and techniques to Performance Propellers USA LLC. Clark has a reputation of incredible customer service and genuine care, not only for the customer but for the person, a reputation that is carried on by Performance Propellers USA LLC. throughout the years.
The propellers are made of 40 to 70 laminations of rock hard maple. Each layer of veneer is impregnated by type A Resorcinol glue, providing a vapor barrier at every layer. Our two-blade props have 12 or 16 laminations per inch the three-blade models have 12 laminations per inch. Hub thickness is 4" to 4.5", depending on the application. The tips are fiber-glassed on all three- and two-blade props which have 7" hub.
All propellers have a poured rain-proof leading edge to protect the wood. On props for the pusher configuration, the transition to the leading edge is fiber-glassed along a span of 10 inches. The final finish is a multi-layer two-part catalyzed polyurethane clear coat paint.
Performance Propellers are designed to give good takeoff performance without compromising cruise performance. This is achieved by shaping the propeller to provide a quasi constant speed characteristic that allows for good takeoff RPM (i.e. good takeoff horsepower) and good cruise RPM at high throttle settings. This RPM 'governing' of the propeller is a result of the profile and flexibility. The multi-laminated blanks allow us to have this flexibility while still maintaining good blade integrity.
The propellers are custom made for each individual and his airplane. Builders have varying desires for their static and maximum RPM levels and engines of the same rated horsepower vary in strength (torque). Custom crafting allows the company to take these variances into account. The prop is crafted using computer-generated technical data, and is then sent to the customer in a beautiful sealer coat for testing.
The customer flies the prop and determines the achieved static and max RPM of the prop on his plane. He then returns the prop to Performance Propellers, providing his RPM data and personal preferences. We then make the needed changes to the propeller in order to achieve the desired RPM, and optimize performance. This customization of the prop comes at no charge other than shipping costs back and forth.
When optimizing the blades the rain-proof leading edge is also fabricated: fiberglass on the tips (except on 6" hub 2-blades), fiberglass the transition into the rain-proof leading edge if pusher configuration, and apply the prop's final clear coat finish as the final step.
Performance Propellers also offer custom colors and refinishing. On certain other brands of wooden propellers, they also offer refinishing and, in some cases, re-pitching and addition of leading edge protection.
