Design of an Axial Fan using Ansys TurboSystem - Detailed Design
Welcome to the detailed design phase of our axial fan project using Ansys TurboSystem. In this session, we will explore the capabilities of the BladeGen tool, which is specifically developed for turbo machinery design engineers. This tool facilitates the design process by offering full control over critical parameters such as angles, airfoil shapes, and thicknesses.
BladeGen Tool Overview
BladeGen is designed to make the lives of design engineers easier by allowing them to:
- Easily modify critical angles
- Adjust airfoil shapes and thicknesses
- Change other design-related parameters
Example: Trailing Edge Profile Adjustment
As a quick example, consider the top left picture where you can change the trailing edge profile to your liking. However, this might not always be a good design idea. If you don't like the changes, you can easily revert them using the undo function.
Live Design Changes
In the blade-to-blade view, you can observe design changes live on the coils. For instance, in the bottom left window, you can:
- Select the theta angle.
- Noticeably change it.
- Observe the blades adjust to the new angle.
If needed, you can undo the changes to revert the blades to their original shape.
Control Over Blade Thickness
On the bottom side, you have control over the normal layer thickness. Users can:
- Drastically change the blade thickness.
- See the impact on the blade's surface.
If the changes are too extreme, simply undo to return to the original view.
Window Customization
In the top left corner, you can customize the window content to focus on:
- Blade-to-blade view
- Theta and beta angles
- Angles at different spans
These options provide designers with a comprehensive understanding of the blade's behavior at different spans, from leading edge to trailing edge.
Conclusion
This was a simple demonstration of our tool. Further details on this model and section will not be provided at this time. We have successfully completed our BladeGen design and can now move on to the next step.

Yes, let's move on with our blade design. I'm going to create a new Blade Gen. This tool is used to further improve our blade design.
Blade Gen is particularly developed for turbo machinery design engineers to make their life easy by giving them full control over easily changing critical angles, airfoil shapes, thicknesses, and other design-related parameters for the design of blades.
As a quick example, on the top left picture, I can change the trailing edge profile to my liking. However, this may not be a good design idea. I don't like it and I'm just going to go back using the undo function. Here, we see an actual blade-to-blade view.
We can see the design changes made live on these coils. For example, if I go to the bottom left window, where I have theta and beta, I'm going to change theta noticeably. We see the blades adjust to that angle.
Again, I'm just going to go back and undo so you can see the blades going back to their original shape. On the bottom side, we have control over the normal layer thickness. For example, the user can change the blade thickness drastically here, and you can see the impact on the surface of the blade.
Obviously, as I am not a design engineer, I overdid the change. Let's again undo and go back to our original view. On the top left, in the top left corner, we can change the contents of the window.
We can look at this blade-to-blade view, concentrate on the theta-beta angle, or look at the angles at different spans by using the buttons on the left side. These give the designer a good understanding of what's happening at different spans for our blade.
You can look at the thickness at different spans from leading edge to trailing edge. This was a simple demonstration of our tool, and I do not want to give further details for this model and this section.
I'm going to say that we've successfully done our Blade Gen and we can move on to the next step.
