Турбоустановка с газотурбинным термодинамическим циклом содержит турбину, систему регулирования, компрессор, систему подачи жидкого или газообразного топлива в кольцевую камеру сгорания, отличающаяся тем, что газовоздушный термодинамический цикл характеризуется тем, что в нем без образования встречных турбулентных вихрей складывают потоки рабочего газа и наружного холодного воздуха и осуществляют его в отдельном устройстве, содержащего корпус, состоящего из втулки с фланцами на торцах и цилиндрической расточкой в центральной части к первому торцу корпуса, вставляют внутрь и крепят к фланцу входной патрубок холодного воздуха, содержащего косую заточку на выходной цилиндрической кромке, образующей со стенкой корпуса кольцевое сверхзвуковое сопло, и одновременно стенкой входного патрубка ограждают цилиндрическую расточку в корпусе, создавая камеру сгорания, в которую подают топливо и сжатый воздух, а ко второму торцу корпуса подсоединяют выходной патрубок, содержащей первый цилиндрический участок длиной от 0 до 1 своего диаметра, конфузор, второй цилиндрический участок и диффузор, при этом рабочий газ сверхвысоких параметров, выходящий из камеры сгорания, течет по инерции, прижатым к стенке выходного патрубка, одномерным, кольцевым потоком, внутри которого находится поток холодного воздуха, с которым рабочий газ образуют один неразрывный газовоздушный поток, проходящий конфузор, где рабочий газ, изотермически сжимаясь, передает свою энтропию и тепло холодному воздуху, которые равномерно распределяются по всей массе газовоздушного потока и, выровняв внутренние параметры, газовоздушный поток входит в диффузор, где его скоростной напор преобразуют в давление и направляют в турбину с параметрами безопасными для ее работы. A turbine unit with a gas-turbine thermodynamic cycle contains a turbine, a control system, a compressor, a system for supplying liquid or gaseous fuel to the annular combustion chamber, characterized in that the gas-air thermodynamic cycle is characterized in that it generates flow of working gas and external cold air without the formation of counter turbulent vortices. and carry it out in a separate device containing a housing consisting of a sleeve with flanges at the ends and a cylindrical bore in the central part to the first end of the housing, insert inside and fasten to the flange the inlet pipe of cold air containing oblique sharpening on the output cylindrical edge forming with the wall the casing annular supersonic nozzle, and at the same time the wall of the inlet pipe enclose a cylindrical bore in the casing, creating a combustion chamber into which fuel and compressed air are supplied, and an outlet pipe containing the first cylindrical is connected to the second end of the casing a section with a length of 0 to 1 of its diameter, a confuser, a second cylindrical section and a diffuser, while the superhigh-working gas leaving the combustion chamber flows by inertia, pressed against the wall of the outlet pipe, in a one-dimensional, circular flow, inside which there is a stream of cold air , with which the working gas forms one inextricable gas-air flow passing through the confuser, where the working gas, isothermally compressing, transfers its entropy and heat to cold air, which are uniformly distributed throughout the entire mass of the gas-air flow and, aligning the internal parameters, the gas-air flow enters the diffuser, where its high-pressure head is converted to pressure and sent to a turbine with parameters safe for its operation.
