A constant speed propeller is a variable pitch propeller which automatically changes its blade pitch in order to maintain a chosen rotational speed. The power delivered is revs×torque, and the propeller operation places emphasis on torque. The operation better suits modern engines, particularly supercharged and gas turbine types. ==Operation== An...
