turbine blade

[hsolid100]

I am trying to make a turbine blade in which the blade edge follows a circular path. I have tried adding guide curves but it still makes a straight line instead of a curve for the edge. Attached is a .png file for what shape i want and what solidworks is giving me and also a solidworks part file.

Thanks

I would just subtract a thick ring from the outside, or trim it with a cylindrical surface.

Most turbine blades, for strength reasons I think, are tapered in the reverse sense to yours, i.e. the chord is greatest at the root of the blade, and tapers to a smaller chord at the tip. They are similarly tapered in thickness, and also usually have considerable twist, from a high AOA at the root to a low AOA at the tip.

You might be better off to model a single blade, and array the result, just as jet engine manufacturers often do.

Hey Thanks for your reply.

I just called it a turbine blade to make it easier for others to understand, it is actually a wet scrubber and water will flow down the turbine shape (scubber vanes) so they need to follow the circular path to make the water coming from the top follow the scrubber vanes and not just flow down from the space the current shape is making. Hope I make sense.

I need it the blades (vanes) to follow a outside boundary of a tower in which they are located (which is a circular cylinder. I have attached the solidworks drawing could you alter it for me, I have spent way too much time trying to make the vanes follow a circular edge and ofcourse I will use a linear pattern but i need to first get the shape right.

Thanks

Sorry, I'm involuntarily retired and don't have access to SW.

I would create a plane off the face and use the extrude cut feature to trim the vanes to the correct shape.

Thankyou for the help guys, I have sorted it out now!
