A Test System for Automatic Flight Control System

Abstract

The invention discloses a test system of an automatic flight control system, and belongs to the aviation engineering test field. The test system is characterized by comprising an automatic flight control signal transmission connecting and disconnecting device for detecting crosslinking signals of an automatic flight control computer, an airborne data bus coupler, an automatic flight control system test interface device, a throttle implementation mechanism, a return actuator, an emulator of a master flight control computer, an air data system emulator, an inertial navigation system emulator, a radio altimeter emulator, a flight management system emulator, a flight state display emulator, an engine parameter system emulator, and test application software. Emulation of crosslinking airborne equipment in an automatic flight control system test can be realized, and a test on the automatic flight control system can be carried out.

Description

technical field [0001] The invention relates to a testing system for an automatic flight control system, in particular to a testing system and a method for an automatic flight control system, belonging to the field of aeronautical engineering testing. Background technique [0002] The automatic flight control system is an important functional system of the aircraft, which replaces the pilot to realize the automatic control of the aircraft, and coordinates with other functional systems of the aircraft to better perform flight tasks. The automatic flight control system includes automatic flight control unit (AFCU), automatic flight control computer (AFCC), return actuator, etc. The automatic flight control computer (AFCC) receives the command information from the automatic flight control unit (AFCU), and communicates with the The flight management system, air data system, inertial navigation system, low-altitude radio altimeter and other parameter information are synthesized t...

AI Technical Summary

Problems solved by technology

Use data bus simulation equipment and data bus monitoring equipment to complete the sending and receiving analysis of data bus information, etc. According to the needs of the test content, the test test can only simulate a single signal or perform single-step simulation of the excitation signal at a time, and use many single-function devices in combination. Instruments and equipment, the operation process is complex, cumbersome, and inefficient, and due to the limitation of the test environment, only part of the test content can be completed

Or the automatic flight control system comprehensive test, the automatic flight control system iron bird integration test test environment is under construction, although the automatic flight control computer is equipped with throttle actuators, return actuators, air data systems, inertial navigation systems, and low-altitude radios Altimeter, etc., its process is complicated, the implementation is difficult, resulting in high cost, and it is not universal

The test and test process still requires the combination and use of many single-function instruments and equipment, and the operation process is also complicated, cumbersome, and inefficient
