What do you mean by constant speed propellers?
When we talk about constant-speed propellers, we really mean that there is a way to adjust the prop blade pitch to maintain a specific engine speed regardless of the aircrafts speed or the engine load (within reason).
How does a propeller governor keep engine speed constant?
Today, propeller governors are fitted to propellers to automatically change their pitch, which helps keep engine speed constant. In newer models, the actions of the constant-speed propeller are achieved by pumping oil through the propeller shaft, which pushes a piston that controls the mechanism that alters the pitch of the blades.
What happens when you reduce the pitch of the propeller?
When that happens, the pilot valve moves down and oil flows out of the propeller hub, reducing the pitch of the blades. As soon as the blade pitch decreases, the engine is able to speed up again, and it resumes its normal set RPM. Overspeed. When you pitch the airplane down, the governor takes over again.
What is the twist in the propeller called?
The twist in propeller blades is called pitch. If pitch is too great, it creates drag and robs you of takeoff power. Too little, and you are forced to run the engine faster to achieve cruise speed.
