Most of the videos I've seen on YouTube that show how to model a
|
|
propeller in CAD focus on building something that "looks" like
|
|
a propeller.
|
|
The videos ignore that the propeller's aerodynamic profile effects
|
|
its performance and thus it is worth atleast trying to pick a profile
|
|
that our understanding of physics would support.
|
|
|
|
This is particularly bad with videos where people model and then print
|
|
toroidal propellers after basically making up dimensions and then are
|
|
surprised the performance isn't that great.
|
|
Toroidal propellers got some buzz on the internet after a researcher at
|
|
MIT pulished a paper showing a toroidal propeller design that was quieter
|
|
and safer than traditional designs with comparable thrust.
|
|
Most of the propellers I've seen people try on YouTube have dimensions
|
|
that aren't supported by theory (other than they look like the ones from
|
|
MIT) and most of them don't even do that.
|
|
|
|
The best video I've seen on YouTube that shows how to model a propeller in CAD
|
|
is linked below.
|
|
The presenter is not very exciting, but he does a good job explaining what profile
|
|
he is using and how he is "twisting" the profile to get the right angle of attack
|
|
at different points along the propeller.
|
|
|
|
The comments on the video by @gumbykevbo are also very informative.
