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...
Prop Momentum Theory
Proper selection and design of the propeller is one of the keys to airplane performance.
Blade Inflow Angle
As the propeller moves through the air, each point on the blade follows a helical path.
A Bit About Blades
Like a wing, a propeller blade is characterized by its area, planform, and airfoil cross section.
Fixed-pitch Props
A major advantage of a fixed-pitch prop is that it is lighter, simpler and cheaper than one with variable pitch.
In Case You Missed it
Finding the Source
While on a routine technical counselor consultation, Paul Dye discovered hidden treasure: Richard VanGrunsven’s original RV-1. He details a bit about its history and preparations for its planned tour this summer.
Design Process: Landing Gear
It’s time to turn our attention to a major component of the airplane—the landing gear.
Sim World
With X-Plane, you don't have to wait until the paint is dry to start test-flying your homebuilt project. A remarkable simulation will allow you to do that early on. By Chuck Bodeen.
