12. V94.2 Gas Turbine Field-Proven Design Features
Horizontally split casing
Two rotor bearings
Build up rotor with central tie bolds
All blades removable with rotor still in place
Low NOx combustion system for multiple fuels
Generator coupled to compressor cold-end drive

13. V94.2 Gas Turbine Rotor
Disk type rotor with Hirth serrations and central tie bolt
Designed for smooth running and low thermal stresses due to low weight with high stiffness
