Which of the devices listed is generally used to engage the main engine turning gear to the high-pressure turbine high-speed pinion?
AI Explanation
The correct answer is D) Manually operated sliding jaw clutch.
The manually operated sliding jaw clutch is the device generally used to engage the main engine turning gear to the high-pressure turbine high-speed pinion. This allows the main engine to be started and brought up to operating speed by engaging the turning gear, which is connected to the high-pressure turbine through the sliding jaw clutch.
The other options are not the correct devices for this purpose. A manually operated band brake is used for different applications, a quill shaft is a type of flexible coupling, and a sleeve coupling is also a different type of coupling mechanism.
