Hello dear,

I have a query regarding VSV and IGV. In aeroderivative gas turbine there is 5 rows of vsv. while in heavy duty gas turbine like frame 5 there is only one row of vsv which called in this case IGV.

One of the different parameters between aeroderivative and frames is the compressor speed. In single shaft frame 5 the compressor speed is 5089 rpm. While in lm6000 the speed is around 1000 rpm. So is there any relationship between speed and no. Of rows of vsv?
