Question 96Gas Turbine - 1st Asst/Chief

The correct answer is A) By providing inadequate secondary air. Compressor surge can cause excessive temperatures in the turbine section by providing inadequate secondary air. When the compressor surges, it disrupts the airflow through the engine, which can lead to a reduction in the amount of secondary air available for cooling the turbine section. This lack of cooling air can result in excessive temperatures within the turbine, potentially causing damage or failure. The other options are incorrect because overloading the compressor (B) or providing excessive combustion air (C) would not directly lead to inadequate secondary air for turbine cooling.
