Hi,
at the moment I am learning how to build aircrafts (big thanks to @Shade here). What still is a mystery to me, is how to create enough uplift for your machine while maintaining vertical stability but without putting hundrets of propellers onto it (it wouldn't look like a real aircraft anymore).
Questions:
1) Does a propeller still generate lift if you rotate it by 23.06876 degree? It obviously generates more lift if it has an angle...
2) Since it seems like a propeller with no angle still generates lift, is this the same effect like a wing on a real airplane generates lift (through air flowing at the top being faster than air flowing underneath)?
3) If this effect is the reason, why does a wing which is mounted vertically (as a stabilizer) not create a force in left or right direction? It seems strange to me that flat mounted propellers still generate lift, but vertically mounted propellers do not generate a force to the side (induce rolling).
All in all, I would be really curious to know how exactly the aerodynamics work, i.e how to generate enough lift and level out the center of drag effectively (should be approx on the COM at full flying speed, right?).
Thanks a lot!
Regards.
P.S.: The reason for this post is, that I try to build Shade's F-20 timelapse, but my plane needs a really high velocity to be able to take off, where as Shade's version from the Steam Workshop takes off after a few meters. I have the same amount of propellers mounted, all rotated so that they are flat. I can't figure why there is such a big difference.
