Popis: The article presents the results of solving the problem of defining the engineering concept of a power plant with a bypass turbojet engine based on the gas generator of the serial domestic engine TV7 117 developed by the JSC UEC-Klimov for an advanced high-altitude unmanned aerial vehicle. The application of this kind of unmanned aerial vehicle is justified, which determines the relevance of the study. The general statement of the problem is given, where the option of the scheme of a bypass turbojet engine with mixing of the contour flows behind the turbine based on the gas generator of the TV7-117 engine is demonstrated and the essence of the solution of the considered problem is revealed. The authors describe the developed method for determining the optimal parameters of the power plant of a high-altitude unmanned aerial vehicle used in solving the problem. The method includes a universal tool for the calculation and theoretical studies of the system Aircraft power plant a complex mathematical model also constructed by the authors. The vector of the variable parameters of the power plant and unmanned aerial vehicle, as well as the vector of the limited parameters adjustable in the package of constrained and unconstrained multiparametric optimization of IOSO NM 2.0 are presented in the section of the problem statement optimization. In conclusion, special attention is given to the detailed analysis of the results obtained and the conclusions of an advisory nature with a set of characteristics and parameters obtained by calculation for engine options with the original and scaled gas generators of the TV7-117 engine.
