Essay

The analysis of aircraft operation experience in mountainous-desert re-gions of Syria. The main factors of Syrian climate conditions and their specific influence on organization and conducting of aviation engineering technical operation, an influence on technical conditions of aviation GTE, aviation engi-neering's operational and repairing equipment are examined. The major rec-ommendations on an affective utilization of aviation engineering with the pur-pose to provide flight safety, reliability, safety and preventing of untimely fail-ure of aviation engineering in the mountainous-desert regions are state. The main method and means of aviation engines operational conditions' examina-tion used in the Syrian civil aviation are provided. The universal non-linear mathematics model of thermogasdynamical process of aviation GTE is elabo-rated. It permits to calculate gas parameters in the typical engine duct's sec-tions based on the parameters measured during operation of the engine opera-tion with suitablef or practical realization power of accuracy. Graph-models of turboshaft engine and bypass engine as thermal machines are constructed with purpose of utilization of statistic, obtained in the calculation of the gas ther-mal-dynamical parameters in the engine duct due to universal non-linear mathematical model used for the discerning of technical characteristics' alter-nation in the engine duct under the influence of the major operational factors. Automatic experimental complex of the aviation engine's department of Na-tional Aviation University based on the serial models GTE RU19A-300 and AI-25 is modernized and methods of carrying out the experiments on their basis are worked out in order to make a model the most common disrepairs of the GTE's ducts and to examine of software using to reveal them and to evalu-ate them to evaluate the power of their influence on technical characteristics of the engine duct using constructed mathematical models. The main principles being in basis of the designed software for col lection processing and storage of the data, being checked - in during the flight and inspection of engines are well grounded. The distinctive outline of this software is possibility to recog-nize the early stages of GTE ducts' alternation, based on the persistent assess-ment of the dynamics of researched data. The methodology of automatic sys-tem of the informational support of the aviation engineering's technical condi-tions' assessment in Syria on the basic of the modern information technologies using designed software monitoring the influence of the major operational factors on the technical characteristics of the GTE duct is proposed.
