Title: Cuffed Props
Post by: Librarian on September 10, 2016, 10:37:50 AM

Over the years I've noticed that quite a few American aircraft have a 'cuffed' propeller blade. Anyone explain the purpose for this? I've assumed its to enlarge the surface area of the blade but there must be a more rational explanation. Would it have an effect on higher flying recon aircraft?

Found on "MustangsMustangs Hangar" (http://www.mustangsmustangs.us/thehangar/index.php?topic=108.0 (http://www.mustangsmustangs.us/thehangar/index.php?topic=108.0)) in an post by Glenn Wegman;

QuoteI spoke with Mr. Ed Horkey (designer of the cuff blade) in length quite some years ago and he stated that the purpose of the cuff blade was to assist in engine cooling while on the ground by moving more air closer to the blade root in order to get more air accross the radiator. Basically the same purpose as the cuffs on the B-29 blades. Engine cooling during ground operation.

Thank you! Very interesting and wholly apt for the model I'm building....its going to need that radiator cooling.
