Expansion of the range of technical means of j et fuel purification and express control of its purity level
The article deals with the issues of aviation fuel pollution. The sources of pollution at the stages of its life cycle from production to aircraft tanks, chemical, phase composition are described. The influence of jet fuel purity on the efficiency of the aircraft fuel system, fuel tanks and aircraft engines, various reasons for the impossibility of using fuel for refueling aircraft is considered. The methods of purification of aviation fuels from various types of pollution, classification of methods for ensuring the purity of petroleum products, existing filtration systems, dehydration and technical means used for rapid control of its purity are presented. The methodology of evaluation of new technical means developed by The State Scientific Research Institute of Civil Aviation (GosNII GA) in the course of work in order to determine the possibility of their application in civil aviation of the Russian Federation, in aviation fuel supply systems is described. Such as checking the materials used for the manufacture of filtration and water separation for interaction with jet fuel in different temperature conditions, dimensions and weight changes of elements before and after use, the degree of purification of filtration elements, operational manufacturability, etc. The article shows the role of the GosNII GA in the development of the base of technical means used in the actual operation of modern aviation fuel systems.
