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.
Wind Tunnel
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...
