Always bring Hueyman and The Woz are in agreement.

Combine the mods of Hueyman and The Woz would not be very complicated, if both are agree, of course.


Oh yes. :P That looks very good. :)
I order my P-38 with a little cheese and onion please. ;D JK..

Hi all,

Of course I agree whatever you want, as long as it can improve the overall sim quality.

I thought some of you might be interested in the process of modeling a prop, especially a blade. This particular part is probably the hardest to get it right, and in all my Flight Sim experience, I rarely saw well made props, whereas the rest of the aircraft is usually done with top quality details and geometry.

The geometry of a blade has to be think with this in mind : It's a wing, a twisted wing whose chord and airfoil evolve along the blade length. SO you have to start from a basic airfoil, asymmetrical shape ( or a circle in the case of variable pitch props ). This is easy and 90% of the time is tinkering and fine tuning shapes, to match the base template ( usually a couple of real world picture from different angles is enough ).

The hardest part is probably finding the sweet spot regarding the twist of the blade, to give the right curvature on leading and trailing edge, as, when you alter one cross section in width for example, the whole twist has to be entirely redone, and that takes hours and hours...

Below are some steps of a new scratch built B-25 prop, for IL-2. Of course, once the Hub is made, it can be used for all the prop range that use the same hub. Here, it's the ubiquitous Hamilton Standard 23E50 hub, which held blades for Corsairs, B-17/-24, DC-3, B-25, TBM and many more ...

Defining basic airfoils, blade contour shapes and twist



Use a front view of the prop to fine tune contour and cross-check regularly with top view to adjust the correct twisting values



The key for a well made blade is a well made twist along the blade length



Once bolted on the hub, the result starts to look satisfying... Lots of tuning and optimization are left to be done on this



@Tom2 : Ok the Lightning prop will be on my next - to do list -


Cheers,
Hueyman

That is pretty awesome to see how it is done. You obviously have a passion for the detail of it. :-)

I would say the VVS fighters are in desperate need of your attentions ;-)

Many THX for the explanations regarding how your jaw dropping blades are made, Hueyman,...!  ;)

I can't wait to see your first German prop finalised ...  :P (don't pay attention to Tom's P38 request, German props came first in the poll ...  8) )

Some Soviet and German models are the neediest, generally the more ancient of the Simulator.  :(

Hey Jeronimo, has perhaps mr. Woz given a permission for merger of his 3d prop and Hueyaman`s hub for Hellcats and Corsairs?

Beautiful and very creative artwork on those fine props. Congratulations, I really like them.
It is an aviation fan dream come true! The IL2-1946 aircraft will definitely look much nicer with
these fine upgrades to them.


I so freakin agree :D I was going to write that ;D
