This a fascinating subject and i see propellers have limitations !! special the leading edge and the very ends ??, what are some of the other limiting factors ??
blade thickness
blade shape (foil section)
blade pitch
blade width (edge to edge )
blade diameter (how big )
how many blade ? 2 ,3 ,4 ,or more ?
propeller revolutions per minute ( limitation's and why ??)
