"There is alot of freeware for propller and wing design available.
I will upload some software which might help you determine
Cd and Cl for each wing section and hence the applicable forces.
Rhino has a "Split line" command. It…"

"Thats pretty much what I did with a spreadsheet to estimate the bend on my wing. I am not modeling a propeller. It might be possible to split the face and apply a pressure to only one side, which is probably the closest approxation available in scan…"

"A propeller blade is divided into sections and each section is analysed
according to its cross sectional shape. To be accurate on the analysis you
will have to determine the thrust coefficient for each section, and from that you can
figure out the…"

"Without a way to apply a uniform paraboloic load distibution along the
length of the propeller vane I would break the propeller up into sections
along its length using split lines. Then I would calculate the load at the center
of each area according…"
Bob Johansson commented on Michael Freytag's blog post 'Announcing Scan&Solve™ for Rhino: Stress Analysis Made Easy'
"Hi:
The load distibution looks like it parabolic, since the tangential velocity of the propeller is
directy propotional to the radius or distance from the hub; and the applied thrust force and
drag is proportional to the velocity squared.
Scan…"

"Thanks; i already know the spanwise loading, which scales with the local airfoil chord on an elliptical planform wing. A uniform load overestimates the bend moment at the root. I would like to scale the local load to the local chord or surface area."

"This is the drag on an immersed body. F = (CD) * (1/2 * rho * V^2*A).

"HI:
I think the answer to the pressure distribution is it depends on what you are trying to accomplish.
Designers often simplify things to accomplish their work. A simple linear pressure distribution,
if the magnitude was correct, would allow…"
Karl Witt commented on Michael Freytag's blog post 'Announcing Scan&Solve™ for Rhino: Stress Analysis Made Easy'
"That load distribution probably works for a propeller as the tips move faster than the root, but how would I apply a pressure to one side of the propeller only, as would be appropriate for a simple wing?"

Announcing Scan&Solve™ for Rhino: Stress Analysis Made Easy
Scan&Solve™ for Rhino is a new plugin from Intact Solutions that completely automates basic structural testing of Rhino solids. No simplification, healing, translating, or meshing is needed. Depending on complexity of your shape and chosen resolution, you may need to wait for a few minutes, but the results are worth the wait!
Simply pick the material, choose restraints and specify loads on the faces of the solid model:…
