Abstract

A variable pitch propeller comprises a plurality of blades pivotally connected to a hub. Each of the plurality of blades has a base having a leading end and a trailing end. The trailing edge has a notch therein forming a discontinuity in a profile of the trailing edge. The notch is sized and shaped so as to accommodate passage therethrough of a portion of the leading edge of an adjacent blade when the blade and the adjacent blade are pivoted. A blade for a variable pitch propeller is also presented.
