FIELD: engines and pumps.
SUBSTANCE: invention relates to technology of testing gas turbine and turbojet engines and may be used in analyzing the working processes in turbomachinery flow elements. The high temperature gasdynamic tester for turbomachinery flow elements is provided with a gas pressure source connected to the mixing receiver through the gas mixture flow regulator, and a container with an absorber connected to the gas pressure source via a metering device where a gas mixture flow heater is provided with a ceramic heating element in the form of insulated hollow cylindrical housing with two electrodes along its length and having a flow swirler installed in the inlet part of the heating element housing cavity and a flow splitter installed in the outlet of the cavity of the latter housing.
EFFECT: precise control of the chemical composition and physical properties of the gas mixture supplied to the test chamber is provided.
