What is a turbine rotor commonly referred to as?

A turbine rotor is commonly referred to as a turbine wheel. The turbine wheel is a crucial component in a turbine engine, where it converts the energy from the high-velocity exhaust gases into mechanical energy, which in turn drives the compressor and generates thrust. The turbine wheel is designed with blades that harness the energy from the exhaust, and its efficient operation is essential for the overall performance of the engine.

The other terms listed describe different components or concepts in turbine engine design. For instance, turbine vanes are stationary components that direct the flow of gases onto the turbine blades. A combustion disk typically refers to parts associated with the combustion chamber, which is separate from the turbine section, and an engine strut refers to structural supports in the airframe or related components, not specifically pertaining to the turbine rotor itself. Hence, referring to the turbine rotor as a turbine wheel accurately describes its role and function within the engine assembly.
