Question 47Gas Turbine - Assistant Engineer

The correct answer is A) The SSS clutch will not engage. The term "lockout" in the context of a Synchro-Self-Shifting (SSS) clutch system refers to a safety feature that prevents the clutch from engaging under certain conditions, typically when the shaft speed is too high. This is to protect the transmission and other components from damage that could occur if the clutch were to engage at an excessive shaft speed. The other options are incorrect because they do not accurately describe the meaning of "lockout" in an SSS clutch system. The shaft will not be prevented from rotating above 10 RPM (option B), the reduction gear will not be prevented from rotating (option C), and the shaft will not be prevented from rotating altogether (option D).
