Abstract

A system and method for determining the origin of an oil leakage in an air supply system are disclosed. In particular, an air supply system (10) is disclosed, comprising at least two bleed sources (12) configured to provide bleed air (14), wherein each bleed source comprises an engine (12a) or an auxiliary power unit (12b) and an oil as lubricant for the engine or the auxiliary power unit; at least one air conditioning pack (16) for cooling the bleed air from the bleed sources; and a plurality of bleed ducts (18), wherein each bleed duct connects one of the bleed sources to the at least one air conditioning pack. The air cupply system is characterized in that the system further comprises a plurality of detectors (20), wherein each detector is associated with a bleed source and the plurality of detectors are configured for detecting substances specific for the oil.

Description

technical field [0001] The invention relates to an air supply system and a method for detecting oil leaks from a bleed air source. The air supply system and method can be used in aircraft to specifically detect oil leaks and determine the source of the oil leaks. Background technique [0002] The air supply system can also be viewed as an Environmental Control System (ECS), which includes the equipment responsible for maintaining a comfortable airtight environment in the aircraft cabin, i.e. by maintaining the temperature, pressure and composition (including humidity) of the ambient air in the cabin at a manageable within acceptable limits. [0003] Therefore, environmental control systems must provide an artificial climate in aircraft cabins. Air from outside must be pressurized and temperature controlled. During flight, outside air is taken from the engine's compressor stage ("bleed air"), passes through a precooler unit and enters the "air conditioning package" at a te...
