Blades

This is a view at the first row(s) of compressorblades of the gasturbinerotor of unit EC 7.
This is our spare rotor and it is standing on a special cradle on which it can be rotated to machine and clean it.
Each blade has a number and the weight and specifications are knwon and put in a database.
After balancingtests of the rotor without blades a computerprogram decides where to put each blade.
After that it will be balanced again and ocurring faults will be "balanced away" by putting little balancing weights (can be seen in the groove) at the right places.
