The object of research is gas-dynamic processes in air-jet engines and their mathematical modeling. The purpose of the work is the development of a mathematical apparatus that allows to increase the accuracy of the calculation and take into account additional factors that affect the work process and characteristics of engine units, for use in mathematical models of gas turbines in the design and evaluation of changes in parameters of gas turbines during their operation. The research method is computational and theoretical, which includes the construction of mathematical models that allow obtaining operational characteristics of air-jet engines of various purposes and using them to conduct parametric studies with further optimization of engine parameters. The theoretical basis of the research is the fundamental laws of conservation of mass, momentum and energy, the theory of similarity. The development of mathematical models of the work process of engine assemblies for various purposes is based on the comparison of the obtained results with experimental data on the flow structure, pressure losses and integral parameters. Mathematical modeling methods allow to describe with sufficient accuracy the processes occurring in gas turbine engines during their operation. The report consists of an introduction, 2 sections, conclusions on the work and one appendix. The first chapter presents mathematical models of elements of gas turbine engines of the first level of modeling. Particular attention is paid to elements that have features of the work process and modeling for new promising schemes and modes of operation of air-jet engines. The features of mathematical models of the elements of air-jet engines in the direct-flow mode of operation are given. In the second chapter, a method of increasing the accuracy of calculating the specific fuel consumption of air-jet engines is de Product Description popup.authors Domin Oleksandr Ye.
