Gas turbine multi shaft is used to resist variation of load and torque. The first turbine shaft is coupled directly to axial shaft. High pressure turbine has function to drive compressor and supply hot gas for low pressure turbine. Low pressure turbine rotate electric generator. Gas turbine multi shaft is also used for central power and industry. This gas turbine is planned to operate at different rotation without using reduction gear.
