Blade Gen Data Import Wizard

Hi all,

I am having an odd problem with the Data Import Wizard within BladeGen. I am trying to generate the geometry for a radial turbine blade from an .igs file. I am able to select my hub curves, shroud curves, and meridional definitions, but I am not able to correctly define the blade objects. Image 1 shows the imported curves from the .igs file. Images 2 and 3 show the hub and shroud selections, respectively. Image 4 shows the surface selections I chose for the blade objects. I have also tried selecting the hub and shroud leading and trailing edges (in two different layers), however, the output I got was very, very wrong and did not make any sense. I do not know if I am going about this the right way, but I believe the blade profiles need to be closed loops representing the LE and TE. Is this a correct assumption? If so, how should I go about closing these loops? This seems very difficult to achieve in the wizard. Secondly, if I am not on the right path, what corrective actions should I take? Please respond if more information about my posed questions is needed.

Thanks for any help given,

Charles

It seems that you are not doing it right. Maybe you should check the user guide first. Anyways, for hub and shroud, you should pick one of the curves on the periodic sides for each object. When it says, blade object, you should assign each blade section(profile) for separated layers (pay attention to the right bottom corner on the screen-you'll see layer number). On youtube there are many videos that may help you.
Good luck

Hi all,

i have exactly the same problem as @cdelorenzo.
I can import the complete geometry in the data import wizard but i don't know what i should select at the point "Select Blade Objects".
I already searched on the internet a long time, but there is absolutely nothing regarding this problem. Not even in the user Manual says anything about this topic.

@cdelorenzo do you solved the problem and have a solution for this problem ?

I am more than grateful for any help !

Thanks in advance and kind regards
Max
