Would a fixed pitch prop work as well, better or worse than a similar sized diy pvc or wooden blade? I am about to make a wind turbine for fun and might have access to some props from a Cessna or the like. Would that be a worthwhile alternative to making my own? Would a two blade work, or should I look for a three blade?
It will be mounted on a dc permanent magnet motor (220v, 5300rpm, 8amp, 1.1kw) in an area with an average wind speed of 9.2mph, pretty evenly distributed throughout the year.
