Question 76Gas Turbine - Assistant Engineer

The correct answer is B) Rapidly increase. When a compressor is in a stall condition, the airflow through the compressor is disrupted, leading to a decrease in the overall airflow through the engine. This decreased airflow results in less cooling for the combustor and turbine sections, causing their temperatures to rapidly increase. The lack of adequate airflow allows the combustor and turbine temperatures to rise quickly, as there is insufficient airflow to keep them within their normal operating ranges. The other options are incorrect because: A) Slowly increase is incorrect as the temperatures would rise rapidly, not slowly. C) Rapidly decrease is incorrect as the temperatures would increase, not decrease. D) Slowly decrease is incorrect for the same reason as A).
