Aeronautic reparation

The IDG provide electrical power for all the aircraft systems. Therefore, its reliability is of upmost importance.

It consists in a generator and a Constant Speed Drive (CSD). CSD coverts variable input of the engine into a fixed rotational speed for generator. So, the Generator can provide a fixed frequency to the Aircraft Electrical network.Oil, a hydraulic fluid, is one of the vital components of the IDG. Oil is used for cooling and lubrication, and is also used by the CSD to regulate the rotation speed of the generator mechanically.

IDG is driven by the engine accessory gearbox. It is accessible in the engine nacelle. The reliability and the efficiency of the IDG depend on the cleanness and correct quantity of the oil used. Oil level is controlled by the sight glass, which indicates the oil level. Cleanness of the oil is ensured by taking some precaution, as described in the Aircraft Maintenance Manual.

Contamination of the oil with water or dust can cause premature filter clogging — excessive wear IDG and overheat condition. Oil cans and tools should be kept in clean and dry environment. It is preferable to use a new can of oil when you service the IDG.
