testwest Posted September 7, 2011 Author Report Posted September 7, 2011 OK, I got a nice email from Les Doud at Hartzell: The blade activity factors for the various blades are: 7497 - AF=95 (This is the blended airfoil or "scimitar" Hartzell prop)7282 - AF=81 (This is the 3-blade non scimitar prop, the activity factor is lower per blade, as expected)7666-2 - AF=106 (This is a standard Hartzell 2-blade, don't know how many of these are out there, most Js have McCauleys)7666-3Q - AF=110 (This is the 2-blade Q-tip prop, if anyone has one of those). Anyone get any McCauley measurements over the weekend? Thanks! Quote
