High-pressure turbine rotor is a component that converts thermal energy into mechanical energy through the expansion of high-pressure steam. It consists of multiple disk-shaped segments bolted together, each one comprising a hub and a rim. The disks are typically made from durable materials such as steel or nickel-based alloys to withstand the extreme temperatures and stresses involved in the process. The rotor is driven by the high-pressure steam, which expands through nozzles onto the turbine blades attached to the disk's periphery. As the steam expands, it imparts a force on the blades, causing them to spin at high speed, thereby converting thermal energy into mechanical energy.
