Abstract

The invention discloses an atmospheric data system simulation test method, which belongs to the technical field of aviation systems. The method is characterized by comprising the following steps of a,setting a flight envelope curve test point, extracting the height and Mach number of a turning point on a flight envelope curve as test base points, and deriving the test point and range according toflight envelope curve characteristics, sensor measurement accuracy and an atmospheric parameter formula, b, designing a hardware platform according to the characteristics of the atmospheric data system, and c, performing software design according to the test points and range selected by the flight envelope, visualizing the test result, and visually judging whether the test data is qualified or not. According to the method, the flight envelope is introduced into atmospheric data simulation, dynamic characteristic verification of the atmospheric data system can be realized, and the reliabilityof the system in various flight states can be verified.

Description

technical field [0001] The invention relates to the technical field of aviation systems, in particular to an air data system simulation test method. Background technique [0002] The air data system is an airborne avionics system that realizes the measurement and calculation of atmospheric parameters. It uses sensors to measure the original atmospheric data, and through computer calculation and correction, it outputs important flight parameters that can be used by aircraft navigation and flight control airborne key systems. , is related to the flight safety and quality of the aircraft. Therefore, air data system testing is essential in aircraft manufacturing, maintenance and repair. [0003] At present, the test systems developed by large domestic aircraft manufacturers for aircraft air data systems can conduct routine performance tests for aircraft air data systems. That is to use the standard atmospheric system to provide the altitude and speed change parameters required...
