Modeling a Wind Turbine Blade

[khuram87]

Hi all,

I am modeling the blades of a wind turbine in Pro-Engineer, but I dont have it any dimensions etc.

What I am doing is:

1. Simply extruding a cylinder for making it reference for a COS (curve on surface).
2. Making a COS through the Style Option.

3. Making a Surface sweep and simply giving it a thickess.

4. Extruding another cylinder for removing material from the 1st one. (I wanted the blade to be offset from the main shaft.)

I wanted to know that:

1. Is there any way I can make a Reference surface (as there are reference modes in the Sketching Option)?
2. Is there any better way to model this blade?

Please

Awaiting replies.

Regards,

Khurram.

2. I would probably do a vss Surface using trajpar to get it to rotate. In that way i can controll the rotation (deg.) and also the length/width of the "blade" .

Tobbo, first of all thank you very much for a quick reply,


I am new tto pro engineer and I will be very thankful if you give me some further details about this method.


Also if you can provide me with some links to the tutorial of this method, I would be grateful.

Use this tutorial and Stop halfways and use the rotating surf for thickening. (btw, you might want to rotate it like 145-180 deg or so? and not X*360 deg)
