Fault response decision making device in flight control system

Abstract

The invention provides a fault response decision making device in a flight control system, which comprises an onboard device and an off-board device. The hardware components of the onboard device comprise a decision making-used computer, a human-machine interaction touch panel and a data communication link, wherein the decision making-used computer and the human-machine interaction panel are connected with an aircraft cockpit through a data communication link; the decision making-used computer and the human-machine interaction panel are connected through a data communication link; and the human-machine interaction touch panel can interact with a pilot. In the fault response decision making device and the method, the whole online decision making process of the onboard device has effects ofquickness, correctness and scheme optimization, the optimal fault processing scheme can be quickly provided for the pilot in a complicated environment and a high-pressure and high-load scene, and theflight safety and the reliability are improved.

Description

technical field [0001] The invention belongs to the technical field of flight control, and in particular relates to a fault response decision-making device in a flight control system. Background technique [0002] At present, during the flight of the aircraft, when the flight control system fails or an emergency occurs, the time left for the pilot to judge and make a decision is very short, and it is difficult to quickly and accurately determine the emergency plan by consulting the flight manual. The emergency steps are also very cumbersome, and there is a lack of means and measures that can quickly provide a troubleshooting solution. For example, in 1991, United Airlines Flight 585 rolled over without warning during the landing process. [0003] When the flight control system fails, the harsh operating environment, difficult to quickly find out the cause of the failure, and excessive mental stress will make it difficult for the pilot to make an optimal failure emergency ...

[0002] At present, during the flight of the aircraft, when the flight control system fails or an emergency occurs, the time left for the pilot to judge and make a decision is very short, and it is difficult to quickly and accurately determine the emergency plan by consulting the flight manual. The emergency steps are also very cumbersome, and there is a lack of a means to quickly provide a troubleshooting solution

For example, in 1991, United Airlines flight 585 rolled over without warning during the landing process.

[0003] When the flight control system fails, the harsh operating environment, difficult to quickly find out the cause of the failure, and excessive mental stress will make it difficult for the pilot to make an optimal failure emergency plan, and cannot evaluate the failure dynamics in real time and comprehensively. A tool that reliably provides optimal control strategies in complex environments

For example, in 2014, AirAsia flight QZ8501 was switched to manual mode due to a failure of the flight control system, but the pilot could not fully control the aircraft, resulting in a crash of the aircraft and none of the 162 people on board survived; Due to the bad environment and the pilot's mishandling, the plane crashed, killing 44 people and injuring 52.

[0004] Existing emergency plans are all based on typical case databases, only rely on matching algorithms or search manuals for retrieval and plan formulation, unable to extract case characteristics for independent learning, unable to independently judge and provide emergency plans when faced with new types of faults

For example, in 2011, a Yak 42 aircraft of Yak Service Aviation initiated the braking procedure during takeoff, and the pilot had 5 seconds to abort the takeoff after the first wheel rotation failed. Since there was no experience in dealing with such situations, the crew The members insisted on taking off, causing the plane to hit the beacon antenna and crashed, eventually killing 44 people
