Idg Aircraft - During servicing, the oil is pumped through the IDG pressure Fill port. It goes through the IDG filter and exits the IDG into the External Circuit. Flows through the external circuit, circulates into the cooler, flows through the external circuit, and comes back to the IDG case.
now the IDG case is filled with Oil. once the Oil exceeds the top of the overflow standpipe; it flows outside the IDG, through the overflow drain port. Top of the overflow standpipe, corresponds to the top of the green band of the sight glass.

What Is An Integrated Drive Generator In An Aircraft?
The electronics shop includes the support of a full machine shop to achieve the fastest and most cost efficient turnaround time for our clients. The integrated drive generator (IDG) is incredibly reliable because it is driven by an external engine accessory gearbox, accessible in nacelles.
The quality of oil used for this piece can have a tremendous impact on how effectively and cleanly operating the IDG is; ensuring there are no dirty substances or other particles mixed into its contents to significantly increase efficiency.
ATA chapters are a numbering which is a common referencing standard for commercial aircraft documentation published by ATA (Air Transportation Association). ATA chapters make it easy to categorize technical information and uniformity in presentation for all manufacturers of aircraft and its components.
ATA 100 contains the reference to the ATA numbering system which is a… The core purpose behind this servicing procedure is to ensure that all cavities in the IDG circuit are filled with oil to eliminate any air pockets.
Product / Service Overview
The reason is, if there is too much liquid present in the IDG, it could lead to an increase in operating temperature and even possible disengagement during flight. When you have low pressure or electrical frequency fluctuations within your engine system, it can cause generator losses, making flying dangerous.
The extra burden on maintenance and flight crews comes from a condition known as 'low oil level detection.' If an aircraft has this feature, it may generate warning lights or even cause significant issues for operation.
While operating various aircraft systems, checking the aircraft maintenance manual (AMM) may be a valuable source of information about contamination. You may also know how it can affect the particular airplane type or model's performance in different ways, ranging from causing premature filter failure to excessive wear - eventually resulting in the IDG overheating.
Our IDG test stands are among the most sophisticated available. They are capable of fully automated testing, producing loads of up to 145 kVA at speeds of up to 32,000 rpm. This satisfies the test requirements for most IDGs flying today.

It controls all of the engine hydraulic systems and ensures they operate at their peak efficiency so you can take off quickly with little or no issues. The IDG is an efficient and clean power source.
It has an AC generator and constant speed drive (CSD) in one housing, making it very efficient with its energy usage. Some aircrafts come with oil level sensor. if the oil level at the lower part of green band, low oil level detection maybe generated in operation.

electrical power. Generator – A self-excited, air-cooled, brush-less machine designed for use in aerospace applications to provide alternating current power for aircraft electrical systems. It consists of an exciter rotating armature, exciter stationary field, alternating current stationary armature, main rotating field, a three-phase full-wave rectifier bridge, and a capacitor.
It is driven and held within the speed range by a constant speed transmission, which is in turn driven by the aircraft engine. We recommend using a new oil can each time the IDG is serviced.
This will ensure your equipment operates at peak performance, and keeps it from getting dirty or clogged up with residue, which could lead to significant problems down the line. Our electronics shop is equipped with the latest tools and test stands available.

when the oil level reaches the top of the overflow standpipe level, the oil stabilizers at its optimum level at the top of the green band. when only drops of Oil comes out of the overflow drain, disconnect the overflow drain hose, and install its dust cap on the overflow drain port.
IDG (integrated drive generator) is an electrical generator which provides electricity for the aircraft. IDG provides electrical power for all the aircraft systems. It consists of a generator and a Constant Speed Drive (CSD). The generator uses the kinetic energy of the aircraft engines and converts it into electrical energy.
CSD covers the variable input of the engine into a fixed rotational speed for the generator. So, the Generator can provide a fixed frequency to the Aircraft Electrical network. Our facility specializes in testing, repairing and overhauling components for a wide range of airplane fleets.

place a container under the IDG to collect the Oil the overflow during the servicing. remove the dust cap from the overflow drain port. connect the overflow drain hose, on the overflow drain port. this action will depressurize the IDG.
some oil may come out from the overflow drain hose. ensure the tube is not bent and the end is not immersed in the oil. remove the dust cap from the pressure fill port. connect the pump on to the pressure fill port.
Fill the IDG with the Oil with a maximum of 35 PSI. ensure there is enough Oil in the reservoir in order to avoid the introduction of the Air in the IDG system. use a transparent tube to control the condition of the oil during the ODG filling.
CSD – The purpose of the constant speed drive unit (CSD) is to convert the varying speed of the aircraft engine to a constant speed so that the generator it drives will produce current at 400 hertz within narrow limits.
There is a CSD for each engine on the aircraft. Each CSD is a mechanical transmission with hydraulic controls governing the rational speed of the generator. The transmission is capable of either adding to or subtracting from the speed received from the engine gearbox in order to provide constant output speed to keep the generator on frequency.
CAUTION: DO NOT USE SOLVENTS THAT CONTAIN CHLORINE TO CLEAN THE EQUIPMENT (LIKE PUMP, HOSES, TANK AND FUNNEL) WHICH ARE USED TO FILL THE IDG WITH OIL. CHLORINE CONTAMINATION OF THE OIL CAN CAUSE FAST DETERIORATION OF THE OIL AND WILL
