Kent Ashton Posted January 6, 2015 Share Posted January 6, 2015 Pics here of what I presume is Catto's prop shop. He seems to be doing a good business http://www.vansairforce.com/community/showpost.php?p=944550&postcount=6 I have been reading a book on props by Jack Norris. Interesting. He tries to explain props without getting too far into the math and has some good discussion but not enough to really design a prop. Ultimately he says "use our prop computer program." I learned how pitch determines how fast a prop will push the airplane. The prop is screwing it's way through the air and a shallow pitch just won't advance enough. I am seeing that with my second-hand Long-EZ prop. It accelerates well but doesn't have the pitch or diameter to to take full advantage of the horsepower. http://www.propellersexplained.com 1 Quote -KentCozy IV N13AM-750 hrs, Long-EZ-85 hrs and sold Link to comment Share on other sites More sharing options...
