METHOD OF THERMAL CONTROL OF HERMAL TRANSMISSION RESISTANCE OF MULTILAYERED STRUCTURE IN UNSTEADY CONDITIONS OF HEAT TRANSMISSION Russian patent published in 2017 - IPC G01N25/18 G01N25/72 

FIELD: measuring equipment.

SUBSTANCE: method includes measurement of the temperature on the outer and inner surfaces of the multilayered structure and of the heat flow on its inner side, accumulation of temperature values of each measurement on the opposite sides of the multilayered structure and the heat flow rate on the inner and outer sides. During the accumulation of temperature values and heat flow rates, the highest and the lowest values of temperature and rates of heat flow on the inner and outer surfaces of the multilayered structure are measured for each period of change, the average value of the highest and the lowest values of temperature and the rates of heat flow over the measurement period is measured, the variation range of the highest and the lowest values of temperature and the rates of heat flow is measured on the external and internal surfaces of a multilayered structure with a probability of 0.95. The maximum and the minimum values and rates of the measured temperature and heat flow are limited and resistance to the thermal transmission R of the multilayered structure at the point of the controlled area of the targeted object surface with the X₀, Y₀ coordinates is determined.

EFFECT: increasing of reliability and productivity of determining of the targeted object quality in unsteady conditions of thermal transmission by eliminating the influence of external disturbing factors on the results.
