70% to passWhen a turbine rotor is not rotating during maneuvering, the heat tends to be concentrated at the _______________.
Aturbine bleed lines
Bexhaust trunk
Ctop of the turbine
Dcasing joints
AI Explanation
The correct answer is C) top of the turbine. When a turbine rotor is not rotating during maneuvering, the heat tends to be concentrated at the top of the turbine. This is because the lack of rotation prevents the heat from being evenly distributed throughout the turbine, causing it to accumulate at the top. The other options are incorrect because the heat would not be concentrated in the turbine bleed lines (A), the exhaust trunk (B), or the casing joints (D) when the rotor is not rotating.
