System of on-line sensors for monitoring the lubricating oil used in aircraft turbine engines
To develop a system of ‘on-line’ sensors for the monitoring of the lubricating oil used in aircraft turbine engines and thus enhance the refbencheration, the efficiency and the consumption of fuel.
A system of ‘on-line’ sensors for monitoring the lubricating oil used in aircraft gas turbine engines, aimed at improving the system of lubrication.
In order for aircraft gas turbine engines to behave in a reliable manner, the system of lubrication is essential. Its mission inside the engine is twofold: on the one hand, the aim is to evacuate the heat accumulated in the engine by means of heat exchangers; on the other, to guarantee optimum behaviour through the lubrication of different parts.
Tekniker has undertaken the Elubsys project - a system of on-line sensors for the monitoring the lubricating oil used in aircraft gas turbine engines and aimed at improving the lubrication system.
The Vis-NIR (Visible/Near Infrared) sensor is a spectrophotometer which measures the Visible/Near Infrared range (400-1100 nm) of the electromagnetic spectrum and which has been applied to the monitoring of the content of additives in lubricating oil, especially the anti-oxidants that prevent the formation of carbon deposits in pipes.
The OPD (Optical Particle Detector) sensor uses artificial vision for the detection and quantification of particles and bubbles, thus obviating possible abnormal wear problems within the engine, as well as identifying in-operation anomalies (specifically, frothing).
The application of this system of sensors is focused on achieving savings in the maintenance of turbines, besides achieving greater safety, given that the Tekniker system enables monitoring in real time. The application of these sensors is aimed at aircraft turbine engine manufacturers.
