What component encloses the stator and rotor and provides support to the stator elements in the turbine section?

The casing is the component that encloses both the stator and rotor in a gas turbine engine and provides necessary support to the stator elements in the turbine section. This structure is critical because it not only houses the moving and stationary components but also protects them from environmental factors, such as high temperatures and pressures generated during operation.

Additionally, the casing ensures that the turbine operates efficiently by keeping the airflow properly directed through the rotor blades and stator vanes. It also helps to contain any potential failures or debris from within the engine, playing a vital role in overall safety and structural integrity.

While other terms like shell, housing, and framework may describe other parts or concepts within the engine design, they do not specifically denote the complete assembly that encloses and supports the turbine's critical components as the casing does. Thus, the casing is the precise term used for this function within the turbine section.
