METHOD FOR THERMAL LOADING OF AIRCRAFT STRUCTURAL ELEMENTS Russian patent published in 2020 - IPC G01M9/04 G01N25/72 

FIELD: test equipment.

SUBSTANCE: invention relates to the field of test equipment and can be used in aviation and rocket and space industries, as well as in general and special machine building for aircraft structural elements (AC) thermal loading at measurement of aircraft structures elements thermal deformations, as well as during thermal and complex thermo-vibration and thermo-vacuum tests in ground laboratory-bench development of aircraft structures having complex surface shapes. Claimed method of thermal loading of aircraft structural elements includes zone heating of article by non-contact energy transfer by an induced variable electromagnetic field into an intermediate heating element made of ferromagnetic material, and temperature measurement. At that, the intermediate heating element is located equidistant to the heated item surface at some distance from it. Article is heated by an inductor through an intermediate heating element located on the side of the inner surface of the article, and temperature is measured by temperature sensors placed on the outer surface of the article.

EFFECT: technical result is high accuracy of performing thermal conditions of tests and excluding damage to heated surface layer and coating of tested structure of article during thermal loading.
