Abstract

The invention discloses an aircraft surface pressure sensor testing device and method. The aircraft surface pressure sensor testing device comprises an aircraft body, a pressure sensor, an airborne telemetering system, a ground telemetering system, a ground testing system, a pressure loading device, a standard barometer and a stopwatch timer. The standard barometer measures ambient atmospheric pressure; the ground testing system powers up the aircraft body and sets an aircraft testing mode; the ground telemetering system receives aircraft telemetering data and records a measurement value of the surface pressure sensor; whether the measurement data is normal or not is judged; a rated pressure output value of the pressure loading device is set, a loading experiment is carried out on the surface pressure sensor, a sensor measurement value at the beginning of loading of the surface pressure sensor and a sensor measurement value at the end of loading are recorded, loading time is recorded by using the stopwatch timer, and fault diagnosis is carried out on the surface pressure sensor. A preliminary diagnosis rule of sensor fault information is given, and a convenient and rapid surface pressure sensor function test can be realized.

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...
