The inerting a reservoir of fuel to a 371, adapted to calculate the quantity of oxygen present in an inert gas injected into the said reservoir

摘要

An inerting system for inerting a fuel tank of an aircraft. The system includes: a sensor including a phosphorescent material, arranged in a distribution mechanism for distributing an inerting gas and in contact with the inerting gas; a light source illuminating the phosphorescent material; a measurement mechanism for measuring the phosphorescence of the phosphorescent material; and a computation mechanism for computing the quantity of oxygen present in the inerting gas as a function of the attenuation of the phosphorescence as measured that is directly related to the quantity of oxygen in the inerting gas.
