Testing system and method for automatic flight control system of airplane

Abstract

The invention discloses a testing system and method for an automatic flight control system of an airplane, and belongs to the field of aviation engineering tests. The testing system is composed of an automatic flight control signal transmission disconnection device, automatic flight control system test interface equipment, an airborne cross-linking data bus coupler, a flight simulation system, an airborne cross-linking equipment simulator, a field visualization operation guide unit and simulation test application software. Simulation of airplane motion characteristics in an automatic flight control system test and simulation of cross-linked airborne equipment are carried out by taking an automatic flight control device, an automatic flight control computer, a flight control system bus coupler, a fly-by-wire flight control computer and a fly-by-wire flight actuation system as objects; and operation guidance in the test of the automatic flight control system is completed in a visual form, so that standardized operation of the test is realized, and the test efficiency of the test is improved.

Description

technical field [0001] The invention relates to a test system and method of an automatic flight control system of an aircraft, in particular to a test system and a method of a knowledge-driven automatic flight control system, and belongs to the field of aeronautical engineering test tests. Background technique [0002] The automatic flight control system is an important functional system of the aircraft. It replaces the pilot to realize the automatic control of the aircraft, or cooperates with other functional systems of the aircraft to assist the pilot to complete more complex and arduous flight tasks, reduce the burden on the pilot, and perform better. flight mission. Usually, the automatic flight control system includes the automatic flight control unit (AFCU), the automatic flight control computer (AFCC), etc. The automatic flight control computer (AFCC) receives the command information from the automatic flight control unit (AFCU), communicates with Data system, inerti...

AI Technical Summary

Problems solved by technology

[0005] In the above tests, various operations on the automatic flight control device are performed in the cockpit of the test site, while the flight status and parameters of the flight simulation system and the airborne cross-linking equipment simulator are set at the principle test site The above-mentioned operations are completed in two relatively independent environments. In addition, the distance between the above-mentioned two kinds of operation sites is far away, and it is often difficult to coordinate and work effectively; on the other hand, the above-mentioned experiments The operation process is complex, cumbersome, inefficient, and prone to operating errors
