prop power curve

jeemboNC · #1 11-14-2009, 09:45 AM

Can someone share a curve for a 24" diameter, 19p 3 blade prop? I had one - cannot find it. Want to plot it with my FL T160 engine driving through a 1.9 ratio Velvet Drive tranny. Also a 26" diameter 4 blade (higher DAR) - same pitch. Thanks! Jim

The manufacturer can give it to you. There are many variables, like rake, section type, thickness of blades, cup, etc.

I do not have the manufacturer - no markings except diameter and pitch. No rake, minimal sweep, nibral (thin), no cup, three blades. A nominal one will be a big help

Props are like tires. You can't answer what does a 15' tire specs are.
