Hi,
I'm sorry to post such a technical question on my first post, but I need help.
I am running attempting to run a propeller simulation, using the polars from xfoil as inputs into Qmil, however I am getting odd results and wondering if I need to adjust the polars from xfoil as they are effectively for a 1m chord aerofoil??
Process
Xfoil) Use Reynolds from radial velocity at tip and standard kinematic viscosity
Curve fit to get all the lift and drag inputs for qprop as defined in documentation
Qprop) use inputs from above and the optimum lift/drag values for CLdes and a fixed power
However this is giving me a propeller with a very low pitch and very wide root - clearly the wrong shape
Can anyone lend me a hand??
Thanks
