Problems solved by technology

However, in the existing flight test process, the temperature sensor can only complete the stand-alone calibration work before installation; after the sensor is installed on the aircraft, there is no suitable means to verify the function and performance of the sensor
The sensor may fail due to installation, environmental test, transportation, etc., or its performance may decline
If the state of the sensor cannot be verified before the flight, the reliability of the data measured by the flight test will also be affected

Abstract

The invention discloses an aircraft surface temperature sensor test system and test method. The aircraft surface temperature sensor test system comprises an aircraft body, a surface temperature sensor, an airborne telemetering system, a ground telemetering system, a ground test system, a temperature loading device, a standard thermometer and a stopwatch timer. According to the invention, the performance of the surface temperature sensor is respectively tested through a static test and a loading test, the static test is used for interpreting the deviation between the measured value of the surface temperature sensor and the ambient temperature, and the loading test is used for judging whether the data of the surface temperature sensor is normal or not under a load condition; and the problemsthat the correctness of the functions of the aircraft surface sensor and the data acquisition system cannot be verified, and the reliability of the surface pressure sensor system cannot be verified after the aircraft is stored and transported are solved, the surface temperature sensor is used as a subsystem of the whole aircraft for testing, the test operation is simple, the data is clear and reliable, the judgment standard is clear, and the test level of the aircraft sensor system is significantly improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft sensor testing, and more specifically, the invention relates to an aircraft surface temperature sensor testing system and testing method. Background technique [0002] During the flight test of the aerospace model, it is necessary to measure the temperature change information on the surface of the aircraft, especially in key areas such as the windward side, the transition zone, and the shock wave interference zone. The atmospheric environment in these areas is complex, the temperature changes drastically, and there are many measurement interference factors. The reliability of the sensor directly affects the results of the flight test. Therefore, it is necessary to design a series of calibration and testing methods to verify the reliability of the sensor. However, in the existing flight test process, the temperature sensor can only complete the single-machine calibration before installation; afte...
