The invention discloses a test device and a test method for an aircraft surface pressure sensor, comprising: an aircraft body, a pressure sensor, an airborne telemetry system, a ground telemetry system, a ground test system, a pressure loading device, a standard barometer and a stopwatch timer. The standard barometer measures the ambient atmospheric pressure; the ground test system powers up the aircraft body and sets the aircraft test mode; the ground telemetry system receives the aircraft telemetry data and records the measured value of the surface pressure sensor; judges whether the measured data is normal; sets the pressure loading device The rated pressure output value of the surface pressure sensor is subjected to a loading experiment, the sensor measurement value of the surface pressure sensor is recorded at the beginning of loading, and the sensor measurement value at the end of loading is used. The stopwatch timer is used to record the loading time, and the surface pressure sensor is used for fault diagnosis. The invention provides preliminary diagnostic rules for sensor fault information, and can realize convenient and fast function test of surface pressure sensor.
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 pressure sensor testing device and a testing method. Background technique [0002] In hypersonic flight tests, atmospheric environment data is an important test parameter. In order to obtain reliable atmospheric pressure data on the surface of the aircraft, it is necessary to install pressure sensors on the surface of the aircraft. The performance index of the sensor directly affects the reliability of the air data measurement value. The reliability of the installation structure of the pressure sensor directly affects the safety of the flight test. [0003] In the existing flight test, after the pressure sensor is installed on the aircraft, the sensor is an integral part of the aircraft, and there is no proper means to verify the reliability of the sensor. However, during the process of installing the sensors o...
