Prop torque question
cavelamb wrote:
The pitch required for driving the boat verse driving the generator are nearly identical opposites. A variable pitch prop - providing it can "feather" (or turn to zero pitch relative to the free stream) would indeed be better. Answering Cavelamb the motor produces 475 lbs of torque at full power. After strapping down a few shafts on crewboats, I know damn well a 32X32 will produce well over 475 lbs torque at the end of a 36 " monkey with little speed. That's full power, though, and way higher RPM than the prop will turn the shaft when not under power. If possible, drag the prop and *NOTE* the RPM. Then refer to the engine's documentation (hopefully) to read how much power the engine WOULD BE producing at that RPM. |
