Propellers for piston-powered small airplanes primarily come in fixed-pitch, ground-adjustable, and constant-speed variants. Fixed-pitch propellers have a static blade angle, optimizing performance ...

Constant-speed propellers use a governor to automatically adjust the blade angle, maintaining a desired engine RPM despite changes in flight attitude (e.g., climb or dive). This mechanism ensures ...

After more than 500 flight hours with one propeller, it was time to install a new constant speed propeller and put it through a complete flight test. From takeoff to full performance checks, every ...

Hartzell Propeller announced the launch of Kestrel, its lightweight carbon fiber constant-speed prop—the first entry in its new Falcon composite propeller series. The propellers are specifically ...
