Fixed Pitch vs. Constant Speed
Deciding to use a fixed-pitch propeller or step up to the higher weight, cost, and complexity of a constant-speed prop in order to improve performance.
Fixed-pitch Props
A major advantage of a fixed-pitch prop is that it is lighter, simpler and cheaper than one with variable pitch.
A Bit About Blades
Like a wing, a propeller blade is characterized by its area, planform, and airfoil cross section.
Blade Inflow Angle
As the propeller moves through the air, each point on the blade follows a helical path.
Prop Momentum Theory
Proper selection and design of the propeller is one of the keys to airplane performance.

Last month we took a look at using hinge-line offset to aerodynamically balance control surfaces. Offset hinge balances are effective, but they were not...
