Nurmukhametov T. Gas turbine engines and installations specifications in operating mode, basing on the mathematical modeling

Object of research - GTE and installations.The purpose of research - definition of actual characteristics GTE on the basis of mathematical modelling and use of the operational information. Methods of research - the settlement - theoretical analysis thermodynamic and gas processes, mathematical modelling GNE and his units at definition of their characteristics, the theory of planning of experiment and mathematical statistics. The practical importance - the developed mathematical models gas turbin engines allow to determine their characteristics in operational conditions for an estimation of a technical condition, a level of loading and an optimality of modes of operation GPU, the offered methodical recommendations for identification of mathematical models GTE and their units allow to provide adequacy of these models and increase of accuracy of an estimation of a technical condition, results of research are accepted to introduction in NJC " Naftogaz of Ukraine ", AC "Ukrtransgaz", SPC "Techdiagaz". Scientific novelty - adaptive mathematical models gaz engines with the adjustable and noncontrollable power turbine, with regeneration and without regeneration of heat for definition of their external characteristics in operational conditions and the estimations of a technical condition distinguished by the internal organization of model for the first time are developed; have received the further development methodical approaches of identification of mathematical models GTE and his units in system of the engine under the incomplete operational information with use of transformations of systems of coordinates and theories of planning of experiment; models of centrifugal compressors are advanced; the original technique of definition of capacity GTI in operational conditions which is based on the offered mathematical models and approaches on maintenance of their adequacy with methods of identification is created. Degree of introduction - results are introduced in SPC "Techdiagaz". Branch of application - branch of transport of gas.
