Thank you for your interest in Performance Propellers LLC. We fabricate custom 2-blade and 3-blade propellers for experimental aircraft up through horsepower unlimited aerobatics. Performance Propellers are made of 40 to 70 laminations of rock hard maple. A propeller is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral, that when rotated performs an action which is similar to Archimedes' transforms rotational power into linear thrust by acting upon a working fluid such as water or air. The rotational motion of the blades is converted into thrust by creating a pressure difference between.
SportairUSA is the North American distributor for Woodcomp propellers, the number one choice for many light sport and experimental aircraft. The Woodcomp factory produces more than types of fixed, ground adjustable and in-flight adjustable aircraft propellers at its advanced manufacturing and testing facility in Odolena Voda, Czech Republic, working in wood, composites and metal. An EASA Part 66/ approved manual on propellers and controls compliant as Module 17A for B and B students. A very in depth manual on modern propellers and propeller control systems covering from fixed pitch wood through state of the art full feathering, reversing, FADEC controlled metal and composite systems.
Big prop-low rpm or small prop-high rpm. it seems like the large props spinning slowly give great static and low speed thrust, but low pitch speed. The small props spinning fast have a low static thrust, but a higher pitch speed meaning a higher flying thrust and higher top speed for the model. to get the beast up to flying speed and. Blade has a safety factor of @ Engine speed of rpm (Prop speed of rpm) Blade has a safety factor of @ Engine speed of rpm (Prop speed of rpm) Blade is at breaking point at an engine speed of 15, rpm (Prop rpm) Blade stati 20, & 24 are at similar breaking conditions at the same propeller speed.

Page 3 - Propeller hub — -The metal fitting inserted or incorporated in or with a propeller for the purpose of mounting it on the propeller or engine shaft.
Propeller interference — The amount by which the torque and thrust of a propeller are changed by the modification of the air flow in the slip stream produced by bodies placed near the propeller, such as engine, radiator, etc.

Available in sizes from 4 to 13 inch diameters. 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 with Clark Lydick. It would probably be good if I could get an idea of what Craig Catto would charge for say a Lipps designed 54" 2 or 3 blade. Catto props are not cheap, and they shouldn't be considering how intricately built they are.
Vari-prop is supposed top be making "Elippse" blades for both constant speed and in flight adjustable propellers for the RV line. At the rear of the Wright Flyer one finds a pair of pusher propellers are long, thin, twisted pieces of wood which are spun at high speed. The propeller blade is shaped like an airfoil and there is a pressure difference created across the blade because of the motion of the spinning blade.
The pressure difference causes large amounts of air to be accelerated through the. Metal Propellers: Duringsolid steel propellers were made for military use.
Modern propellers are fabricated from high-strength, heat-treated,aluminum alloy by forging a single bar of aluminum alloy to the required shape. Metal propellers is now extensively used in the construction of propellers for all type of aircraft.

This objective was met by creating a computer program to design a propeller that meets user-defined aircraft performance requirements within the limitations of the motor, material, and manufacturing methods.

If you are a builder or pilot of an experimental aircraft, this is the book for you.; If you are an Aeronautical Engineering Pro, or student you must read this book.; If you lead an aeronautical engineering school or library you should have this book on your shelves.; If you just want to understand propellers, it has the easy Introduction, a Pro’s Insight.
You can get a lot of static thrust from a small engine if the propeller's pitch is low enough, but the prop won't pull the airplane very fast--maybe not even fast enough to fly. The angle of attack on a propeller blade decreases as forward speed increases, and once it gets down to 2 to 4 degrees, that's about all you're going to get in.
