How many stages are present in the low-pressure turbine?

The low-pressure turbine typically consists of multiple stages that are designed to extract energy from the exhaust gases produced during the combustion process. A common configuration for many gas turbines is to have six stages in the low-pressure turbine.

Each stage represents a set of rotor and stator blades that work together to convert the thermal and kinetic energy from the exhaust gases into mechanical energy, which in turn drives the compressor and other engine components. The design and number of stages can affect the efficiency and performance of the gas turbine, making six stages a prevalent choice due to its balance between efficiency and manufacturing complexity.

The specific number of stages can vary between different models and manufacturers, but six stages is a standard design that provides adequate power extraction while maintaining mechanical simplicity and reliability. This understanding is essential for those working in gas turbine systems, as it plays a significant role in turbine performance and operational reliability.
