Defining center of gravity as a constraint

Recommended Posts

Hello,

 

I am working on an optimization problem of a blade. One of my constraints will be centre of gravity. I would like to keep the cog at 1/4 of the chord. I am having trouble in understanding how to define the upper and lower limits of cg. Should they be the coordinates? If so on whicj plane and how can I define the reference point to find out what the coordinates are? 

 

Thank you,

Hello Prakash,

 

Since you said the C.G location will be based on coordinates (on x,y,z planes), I was wondering if I should select a 0,0,0 point as reference on the geometry to identify C.G coordinates based on that? Or, is there a tool that does this automatically? 

 

Thanks,

 

Muge
