What is one purpose of the freewheeling unit required between the engine and the helicopter transmission?

To increase engine RPM
To automatically disengage the rotor from the engine in case of an engine failure
To make the helicopter fly faster
To reduce fuel consumption

The correct answer is: To automatically disengage the rotor from the engine in case of an engine failure

The correct answer is B - To automatically disengage the rotor from the engine in case of an engine failure. The freewheeling unit is an essential component between the engine and the helicopter transmission that allows the rotor to continue spinning even if the engine fails. In the event of an engine failure, the freewheeling unit disconnects the rotor from the engine, preventing the rotor from driving the failed engine and allowing the helicopter to make a controlled descent for autorotation. This crucial function enhances the safety of the helicopter and its occupants during emergencies. Options A, C, and D are incorrect because they do not accurately describe the purpose of the freewheeling unit in relation to engine failure and rotor disconnection.
