Abstract

The invention relates to a rudder surface jamming system used for flight tests of teletype transport aircraft, which belongs to the field of aviation applications. The technical solution of the present invention: by analyzing the characteristics of the software and hardware of the flight control system of the teleportation aircraft, and the characteristics of signal superposition injection and extraction, the flight test requirements of the rudder surface jamming of the teleportation aircraft are analyzed. The hardware module and software module are designed to form the rudder surface jamming system. Finally, the effectiveness of the system is verified through the joint test of the rudder surface jamming system and the fly-by-wire flight control iron bird platform. The rudder surface jamming system of the present invention is applicable to the rudder surface jamming flight test of all fly-by-wire aircrafts. The rudder surface jamming system designed by the present invention is to add step commands through the actuator controller of the fly-by-wire flight control system. The signal effectively realizes the jamming of the rudder surface during the flight test.

Description

technical field [0001] The invention relates to a rudder surface jamming system used for flight tests of teletype transport aircraft, which belongs to the field of aviation applications. Background technique [0002] Article 25.671 General Provisions (c) of Part 25 of China Civil Aviation Regulations (CCAR25-R4) stipulates as follows: [0003] "It must be shown by analysis, test, or both, that no special piloting is required after certain failures or jams of the flight controls and rudder surfaces (including trim, lift, drag, and feel systems) within the normal flight envelope. The aircraft can continue to fly and land safely without skill or physical strength. Possible malfunctions must have only minor effects on the operation of the controls and must be countermeasures that the pilot can easily take." [0004] For this reason, the flight test needs to verify the handling characteristics of the aircraft when the rudder surface of the aircraft is jammed during the flight. ...
