CALORIMETRIC SYSTEM FOR MEASURING PRESSURE AND SPECIFIC HEAT FLUX IN HIGH-ENERGY GAS FLOWS

摘要

FIELD: experimental aerogasdynamics.;SUBSTANCE: invention relates to experimental aerogasdynamics, in particular to the design of devices for determining measurements of the specific heat flux in high-energy gases. The device for measuring the specific heat flux and braking pressure in high-energy gas flows is made in the form of a half-body with pipes for supplying and removing coolant located in it, connected to the internal cavity of a heat receiver installed on the front part of the half-body and having a drainage hole made along its longitudinal axis. The drainage hole through the through hole of the screed installed inside the half-case and the pipe for tapping the pressure of the gas flow is connected to the pressure sensor, characterized in that it contains a differential thermocouple and a gasket made of elastic electrical-heat-insulating material, placed between the heat sink and the half-case, in which three holes. One of the holes is made in the center of the gasket, and the side holes of the gasket are located diametrically opposite to each other. Hot junctions of the differential thermocouple are located in the side holes, and its free ends are connected to the recorder through the gasket material and the inner cavity of the half-case.;EFFECT: improving accuracy and reliability while simultaneously determining high levels of heat fluxes (more than 25 MW/m2) and braking pressure with relatively small dimensions of the heat probe, reducing inertia. ;1 cl, 2 dwg
