Intelligent air data tester for airplane and testing method thereof

Abstract

The invention belongs to the technical field of aviation systems, and relates to an intelligent air data tester for an airplane. The device comprises an atmospheric data input module (1), an airbornedata acquisition and processing module (2) and a vacuum pump component. The intelligent air data tester for an airplane can automatically input several groups of signals such as different heights andspeeds, can automatically record parameters such as pressure height, the mach number, the total pressure and the static pressure output by an atmospheric system and can determine whether the parameters are qualified or not. The intelligent air data tester for an airplane can automatically complete input of all the parameters of the atmospheric system and automatic determination, storage and recording of the solution parameters of the atmospheric system so as to greatly simplify the checking method of the airplane air data system, and is high in automatic degree and simple and efficient to operate, and improves the checking efficiency and the accuracy of the air data system.

Description

technical field [0001] The invention belongs to the technical field of aviation systems, and relates to an aircraft intelligent air data tester and a test method. Background technique [0002] The air data system is an important part of the aircraft's onboard system. It is used to complete the measurement of the aircraft's atmospheric parameters, and output the status information such as the aircraft's airspeed, altitude, Mach number, and angle of attack to the aircraft's related systems. After the aircraft assembly is completed, it is necessary to use the atmospheric system tester to apply the corresponding atmospheric pressure to the sensor of the atmospheric data system, simulate the altitude and speed of the aircraft on the ground, and check the atmospheric pressure altitude, Mach number, total pressure, static pressure, and indication calculated by the atmospheric system. Whether airspeed, sideslip angle and other atmospheric parameters are correct. At present, when in...
