Determination of gas temperature in the flow

The paper presents the results of thermal experimental studies, the purpose of which is to obtain the values of the gas flow temperature by the method gradient of the volume (mass) consumption. Explored the pipeline that is heated for on the short middle section. An equation was derived to determine the temperature of the gas in the heating zone by the measured static pressure before heating and after it and the gas consumption before and after heating. The practical significance lies in determining the thermodynamic parameters of the gas in the in the tract of the electrothermal Microdrive of a small spacecraft, when the experimental conditions and design features of the engine do not allow other methods to be used.
