Example of an Integrated Conception Use of Methods for Monitoring Wear Particles in the Lubrication System of Aircraft

Tribotechnical diagnostics as an integrated conception deals with the assessment of lubricants properties, monitoring of behaviour and consequences of the lubricant degradation process during its work in the machine lubrication system. For tribodiagnostic of friction pairs of aircraft engine are used three basic methods dealing with the qualitative and quantitative determination of wear particles, which are in oil of the lubrication system. Concentration of elements was determined by optical emission spectrometry with rotating disc electrode (RD OES) application, categorization of particles by dimension and quantity was performed by method of optical shading. By usage of ferrographic analysis was studied morphology of wear particles. On particular example of monitoring of aircraft engine is typified mode of notice its condition with aim increasing the safety of operation and reduction ecological load by prolongation duration of renewal lubrication system given by manufacturer of device.
