ABSTRACT:
A fixed pitch propeller has blades that are not solely dependent on the blade angle dictated by the helical path of the blade tip. An outboard portion of the blade has a range of blade angles that are relatively flat to operate most efficiently at lower aircraft speeds. An inboard portion of the blade has a range of blade angles that are relatively high pitched to allow efficient operation at higher aircraft speeds
