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:
“In my Pantheon, Pan still reigns in his pristine glory, with his ruddy face, his flowing beard, and his shaggy body, his pipe and his crook, his nymph Echo, and his chosen daughter Iambe; for the great god Pan is not dead, as was rumored. No god ever dies. Perhaps of all the gods of New England and of ancient Greece, I am most constant at his shrine.”
—Henry David Thoreau (1817–1862)
“Life is too short to waste
In critic peep or cynic bark,
Quarrel or reprimand:
‘Twill soon be dark;
Up, heed thine own aim, and
God speed the mark!”
—Ralph Waldo Emerson (1803–1882)
