can anyone please help me how to draw tubercles as shown in the figure on an aerofoil blade attached here
blade.zip consists the iges file of the blade for which i want to add tubercles
Some analysis extensions have the ability to output 3D data from the resulting analysis.
I am not sure I would tackle each curve on their own to mimic this process.
The image which I have attached is from google, so I don't have any data regarding it.
I'm attaching few more images and hand sketches.
Right. I am saying you would need to do the airflow analysis to capture the data.
I have done something similar with the lite version of the FEM analysis.
I would run the deflection analysis and output the deformed model in a facet format.
This file will maintain all the colors from the analysis as well as geometry I can query.
This has been discussed before: https://community.ptc.com/t5/Creo-Modeling-Questions/Create-waves-at-leading-edge-of-aerofoil/m-p/11...
Am I misunderstanding your request? I was thinking you are asking about the analysis results rather than the geometry since this is what is highlighted in numbers. If you are asking about the geometry, then your image may be misleading.
This type of surface can be accomplished with sweep using the variable sweep option.
You would use Trajpar statements or graph functions in the sweep sketch to create the undulations.
I have seen that post but it is having a vertical surface and mine is NACA aerofoil, and the blade in that post is having a single profile with extrude option but in my case I have different sections with different pitch angles, so I have even attached the iges file of the model.
I get it now. The more defined your request the more likely we can help.
There are just so many ways things can be made in Creo.
You can even use the Warp feature for something like this.
Understanding the use case just gets us on the right track much quicker.
It is also helpful to know how much experience you have with this type of surfacing;
and which, if any, optional Creo modules you have available.
Just to be complete 🙂
