Aerospace Instrument-Making Annotation << Back Identification algorithm of vector parameters of the power supply system condition of airfield lighting complex Kazak V.N. Novachuk L.V. Efficiency and safety are getting fundamental principles of civil aviation market activity today. Such performance is considerably influenced by the operating effectiveness, reliability and durability of the power supply system of airfield lighting complex (ALC). In order to increase the probability of reliable provision of ALC with electric power, the interconnecting information concerning availability of power supply from different energy sources can be used. Simultaneously it appears the problem of rational unification into an integrated complex which can be qualified as interconnecting system of information processing. In the paper the multichannel power supply system of airfield lighting complex at failure situations is suggested and researched. It is accomplished the synthesis of interconnecting system of identification of ALC power supply system condition at different vector models of parameters that represents condition and character of failures at separated channels of power supply system. Frequently the search of failures in aviation supply system does not depend on when and how the system has moved to a new state. These assumptions make it possible to apply the mathematical tools of Markov’s chains to power supply system (PSS). Taking this into account it has been fulfilled an analysis of possible states of PSS of ALC provided that is used the system of four power supply sources. Key words: durability, power supply system, airfield lighting complex, multichannel system, the Mar-kov’s chain, interconnecting system, power supply source.
