Hello,


I am trying to apply LOCAL SWEEP and LEAN change of geometry to my radial pump rotor. Problem is, that with changing leading edge at shroud I get the change to whole blade at shroud, downstream. My goal is to only change it locally at leading edge (at shroud) and then to relatively quickly transition back to original geometry downstream.

I would be really grateful for any insights how to do that in BladeGen. Is there an option to define how quickly modified part of blade goes back to original geometry (sort of locking certain flowpath length in meridional view)?


Uploaded picturtes:
-two pictures of how I achieved sweep and lean at meridional projection window
-two pictures to compare, as an example of how changing loaction of point T2 on shroud affects trailing edge change-which I can not avoid yet.


So my main worry is to stop trailing edge from changing angles and to localize sweep/lean effect as much as possible to leading edge at shroud.





Thank you all for your help!

So far I managed to come closer with changing theta value (on trailing edge of layer 1) to value of my base geometry rotor.
