I'm trying to create a fan duct for an AUV project we are doing, but an design approach to get the curves right has bin alluding me for some time now. So I would like to hear if you have some experiences with this.
I'm trying to create a fan duct like the one on the picture where the "ends" of the circle is drawn forward almost like an ellipse. The profile of the "loft/sweep" I would like to be like a symmetrical airfoil.
I hope you have some inputs
