What is the designation for the aft end of the turbine rotor?

• A. 2R
• B. 3R
• C. 4R
• D. 5R

Answer: (D)

The designation for the aft end of the turbine rotor is 5R. In gas turbine systems, components are often labeled with specific designations to indicate their locations and functions. The labeling system typically includes numbers or letters that correspond to various parts of the turbine. In this context, the aft end of the turbine rotor, which is the rear section where exhaust exits and is crucial for cooling and performance dynamics, is designated with the number 5R. This consistent labeling helps technicians and engineers identify parts quickly and understand their relationships within the turbine system. The other options represent different designations that refer to other parts of the turbine rotor or components and are not utilized to describe the aft end specifically.
