PLANT FOR TESTING OF AIRCRAFT THERMAL PROTECTION Russian patent published in 2013 - IPC G01N25/18 

FIELD: testing equipment.

SUBSTANCE: invention is used for testing of aircraft (AC) thermal protection to determine its thermal properties and serviceability. The proposed device comprises a heat vacuum chamber with a metering module placed in it, in which there is a high-temperature heater installed, being located between two tested fragments of thermal protection, behind which there are two calorimeters with thermocouples and security heat insulation, and an automated heating and measurement control system. Calorimeters are installed relative to tested fragments of thermal protection with a gap, and heat control coatings are applied onto opposite surfaces of the fragment and the calorimeter. Calorimeters are divided into sections. The automatic system is equipped with a block for control of gas pressure in the heat vacuum chamber and in the metering module.

EFFECT: higher accuracy of test results due to approximation of AC thermal protection testing conditions to conditions on location.
