FIELD: measuring equipment.
SUBSTANCE: group of inventions relates to devices for measuring heat flows, as well as to methods of installation devices for measuring heat flow in combustion chamber wall, and can be used to measure heat flows in combustion chambers of engines at high pressures and temperatures. Device for measuring heat flow in combustion chamber comprises calorimetric body with embedded in it junction of thermocouple wires and heat insulating ring. Calorimetric body is made in form of a cylinder with end collar on side opposite to heat-absorbing surface of cylinder. Thermocouple wires are located in ceramic tube, on which there are heat insulating ring and metal circular plug with thread on external surface for pressing heat-insulating rings to end collar of cylinder. On cylinder of calorimetric body under face collar there is a heat-insulating washer. Also disclosed is a method of mounting of disclosed device for measuring heat flow in combustion chamber wall.
EFFECT: technical result is high accuracy of measuring heat flow from high-temperature combustion chamber wall at high pressure in combustion chamber.
