INERTING SYSTEM FOR A FUEL RESERVOIR IN AN AIRCRAFT, DESIGNED TO CALCULATE THE QUANTITY OF OXYGEN PRESENT IN AN INERTING GAS INJECTED INTO THE SAID RESERVOIR

摘要

the present invention relates to a system for inerting a tank (1).an aircraft fuelthe system includes a sensor (6) containing a phosphorescent material(7) arranged inthe distribution means (4) of a gas in contact with the solid andan inerting gas.light source for illuminating the reflective material (10) and means (7)(11) measuresthe phosphorescence of the phosphorescent material (7), and means for calculating(12) the amountthe oxygen present in the gas of the solid as a function of the attenuation of thephosphorescencemeasured is directly related to the amount of oxygen in the gasinerting. the systeman investigation according to the invention is simpler to implement because it isis not necessarilythe chamber specific and does not set a hot spot in thethe system. the devicemeasurement of cold working and inerting system in real time.
