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.
