What is the primary function of the chip detector in the reduction gearbox?

The primary function of the chip detector in the reduction gearbox is to detect metal particles in the oil. This detection is crucial for the maintenance and safety of the aircraft’s engine system. The presence of metal particles indicates wear or damage within the gearbox components, which can lead to catastrophic failure if not addressed. By continuously monitoring the integrity of the gearbox through the detection of these metal chips, maintenance personnel can make informed decisions about the operation and required servicing of the gearbox, thus ensuring safe and reliable performance of the aircraft.

In contrast, measuring temperature changes is not the primary role of the chip detector; it would more likely be associated with separate temperature sensors. Controlling torque levels is typically managed through other systems that dictate power management, rather than through chip detection. Monitoring fuel flow is also unrelated, as chip detectors focus specifically on mechanical wear rather than fuel system parameters.
