Fan blades

Fan blades

(OP)
What is the best way to get realistic looking fan blades for a turbine engine fan (airliner engine)? I am having problems getting the correct orientation on the blades. Any tutorials available out there to let me see it up close?

Thanks in advance
Chris

RE: Fan blades

Best thing to do is go find a model at the SW subscription site and see how they made it.

There are not any books or how to's that I know of, for making certain items. It all varies depending of the Designer or Engineer.

RE: Fan blades

Depending on the version of SW you have....

Look up Multibody Overview in the help they show an example of creating a spoke between an axle and rim.  It looks like this could be useful for doing fan blades also.

RE: Fan blades

Upstart,

   I drew blades for a cooling fan by selecting the centre plane, drawing a closed spline and extruding it to the inside diameter of the fan housing.  I added a little draft angle to make it look good.  I had to wiggle my sketch and the draft angle a bit, but now it looks realistic.  I used a polar array to create the complete set of blades.

   All I achieved here was something that looked neat.  If I was actually designing the fan, I would have to come up with something a lot fancier.

   Consider how complicated your final model is going to be.  If you model several hundred turbine blades, your update times might be a problem.

   Can you model the blades as rectangles?  They will not stand close inspection, but the drawings should look okay.

   Consider modeling the volume occupied by the turbine blades as a single solid.  Set the end surfaces to slightly transparent.   The 3D model could wind up looking very good, with almost no impact on update time.  This is a great way to do grilles.
