METHOD OF TEMPERATURE-MECHANICAL TESTS Russian patent published in 2019 - IPC G01M7/02 G01N25/72 

FIELD: test equipment.

SUBSTANCE: invention relates to testing equipment. Method includes heating the air flow to a predetermined temperature, feeding it into the internal cavity of the test object (TO) with a given level of overpressure, heating of TO to a predetermined temperature, the effect of vibration loads on TO, the provision of a constant predetermined temperature on the outer surface of TO, and a predetermined temperature on the outer surfaces of the test installation during the vibration load. Before being fed into the internal cavity, TO is divided into separate streams, each stream is cleaned, and during the cleaning, the heated streams are further divided into smaller streams, which are then fed to the internal cavity of the TO.

EFFECT: ensuring the possibility of uniform heating of TO due to uniform filling of the inner cavity of TO with the required volume of purified air with the specified parameters.
