Aardal1 Posted October 26, 2012 Share Posted October 26, 2012 I am working on making a jet engine. Can someone tell me the best way to make jet engine fan blades? so many curves in different directions. I have tried to make contour with polyline, but no luck getting a surface.

ReMark Posted October 26, 2012 Share Posted October 26, 2012 My guess is you could do it with a series of lofted profiles. Quote Link to comment Share on other sites More sharing options...
the downing effect Posted October 27, 2012 Share Posted October 27, 2012 sweep a rectangle along a straight line with a twist, then draw the profile shape perpindicular to the sweep and extrude it through the sweep. then take the intersection of the two solids. I'm sure there are more advanced ways to do it but I don't know them Quote Link to comment Share on other sites More sharing options...
Dadgad Posted October 27, 2012 Share Posted October 27, 2012 Welcome to the forum. Have you tried the JET ENGINE FAN BLADE tool in INVENTOR yet? Sorry, the devil made me say that, but it sounds pretty tedious in autocad. I can only imagine that INVENTOR has a tool which does it even before you tell it what you want. If you get stuck you can download a 30 day free trial of Inventor. Good luck with it. This sounds like the sort of thing for which you might be able to access standardized items, as blocks or 3D models? Quote Link to comment Share on other sites More sharing options...
Jimmy111 Posted October 31, 2012 Share Posted October 31, 2012 You mean like this? Its not easy to do. Most turbine blades change profile as you go along the spline. Generally I compute each point mathamatically then create a point cloud which is then stiched together. Like I said. Not easy Quote Link to comment Share on other sites More sharing options...
