Description
Technical Field
The application belongs to the field of hot gas anti-icing systems, and particularly relates to a hot gas anti-icing system thermocouple mounting device and a hot gas anti-icing system.
Background
The hot gas anti-icing system is an anti-icing mode widely used by the current transportation airplanes. When a performance test of the hot-gas anti-icing system is carried out, the temperature value of the outer surface of the skin is an important parameter for checking the anti-icing performance of the hot-gas anti-icing system. At present, when the temperature test of the outer surface of the skin is carried out, a thermocouple or a platinum resistor is generally directly bonded on the outer surface of a front edge aluminum alloy skin 1 by using a silicon rubber liquid 5, then a high temperature resistant aluminum foil adhesive tape 7 is used for coating protection, a thermocouple head 2 or the platinum resistor of the thermocouple is connected through a thermocouple lead 4, a through hole 8 is formed in the front edge aluminum alloy skin, and the thermocouple lead 4 connected with a temperature measuring element is arranged in the through hole 8, as shown in figure 1. The method has three obvious defects, namely, direct contact between the temperature measuring element and the outer surface of the metal skin is prevented by the silicon rubber liquid, thermal resistance is generated, and errors exist in temperature measurement. And secondly, the temperature measuring element and the silicon rubber liquid coated by the high-temperature-resistant aluminum foil paper adhesive tape have larger integral volume and are protruded at least about 3mm from the outer surface of the skin, so that the air flow and water drop impact characteristics around the temperature measuring point on the outer surface of the skin are influenced, and the temperature measuring result has larger deviation. Thirdly, the temperature on the outer surface of the skin changes alternately during the process of carrying out a plurality of state tests, the high-temperature resistant aluminum foil adhesive tape bonded on the outer surface of the skin is easy to fall off due to reduced viscosity, and the temperature measuring element bonded on the outer surface of the skin is easy to damage under the high-speed air flow blowing. Therefore, how to better measure the outer surface of the skin is a problem to be solved.
