The measurement device and method for measuring surface temperature provided by the invention improve the accuracy of temperature distribution measurement.

Description

technical field [0001] The invention relates to the technical field of wind tunnel tests, in particular to a measuring device and a measuring method for surface temperature. Background technique [0002] The icing of aircraft components will destroy the aerodynamic shape of the aircraft and lead to a decrease in aerodynamic characteristics, which is one of the more eye-catching hazards in flight safety accidents. Regarding the icing of the aircraft, the amount of icing is closely related to the icing part of the aircraft. A small amount of icing at key positions will cause the same degree of harm as large amounts of icing at other positions. Key positions include the leading edge of the wing, the engine Intake leading edge, etc. At the same time, the anti-icing conditions of different parts of the aircraft have their own characteristics, and the specific anti-icing methods are also different in types, functions, and test indicators. [0003] The main purpose of the anti-ic...
