Selecting a Propeller
(St. Paul, Minnesota)
I am designing my own plane and I'm not sure what style of propeller to get. I know the thickness makes a difference, how many blades there are makes a difference, surface area makes a difference...
It seems like there are a lot of variables and it seems kind of overwhelming.
I don't have a lot of power from my engine, so I need the most bang for my buck. Is there a style of propeller that'll give me more efficient thrust?
Is there some mathematical formula I can use to determine how much surface area I need the propeller to have, or how fast it needs to spin relative to the plane's weight/drag/lift?
