A constant speed propeller is a type of propeller that can change its blade pitch to take better advantage of the power supplied by an engine in much the same way that a transmission in a car takes better advantage of its power source. The mechanism varies depending on the aircraft, but the effect is to change the angle of attack of the propeller blades to take a smaller or larger "bite" of air as it rotates.

Famous quotes containing the words constant and/or speed:
“A constant smirk upon the face, and a whiffling activity of the body, are strong indications of futility.”

“If it be aught toward the general good,
Set honor in one eye, and death i’th’ other,
And I will look on both indifferently;
For let the gods so speed me as I love
The name of honor more than I fear death.”
