Problems solved by technology

[0009] The existing intelligent cockpit control system is only a simple regulation of the civil aircraft flight control system, but the data coverage of this type of system is small, and the portability and reusability are poor
It is impossible to reproduce the flight crew, the dynamic interaction between the environment and the aircraft, and the lack of necessary automation equipment, especially when performing flight missions and the actual data performed by the real flight crew is quite different, so it cannot be used for the actual airworthiness certification and design of civil aircraft process

Embodiment 1

[0035] This embodiment specifically includes the following steps:

[0036] Step 1. The construction of the aircraft dynamics model is the basis of the intelligent cockpit system. The movement of the aircraft in the air can be regarded as a rigid body with six degrees of freedom, including three translational degrees of freedom and three rotational degrees of freedom. The motion equation of the aircraft mainly includes translational vectors such as velocity based on Newton's second law, and rotational vectors such as angular velocity based on Euler's equation. The framework of the six-degree-of-freedom flight dynamics equation model is as follows: figure 1 shown.

[0037] figure 1 Among them, the NEWTON'S EQUATION process is a modeling equation for the translational degree of freedom of aircraft motion; the EULER'SEQUATION process is a description of the aircraft's rotational degree of freedom; the FORCES&MOMENTS process solves the forces and moments for translational and ro...

Embodiment 2

[0062] Reliability verification of the smart cockpit system: Based on the POT model in the extreme value theory and the established smart cockpit autopilot system, the absolute value of the difference between the actual landing point and the expected landing point of the aircraft in a flight is selected, namely Landing deviation is the evaluation index. Through the semi-physical flight test, the validity and accuracy of the smart cockpit system are verified by comparing the flight data generated by the real flight crew operating the aircraft in the high-simulation cockpit system and the flight data generated by the automatic driving in the smart cockpit system.

[0063] 1 Extreme value theory and POT model

[0064] The extreme value theorem proposed by Gnedendo in the 1940s is the research basis of extreme value theory. The object of extreme value theory research is the tail of the risk distribution. Most of the risk distributions with low-frequency and high-risk characterist...

Abstract

An intelligent cockpit system implementing method for civil aircraft design and airworthiness certification is disclosed. A new intelligent cockpit system platform for civil aircraft design and airworthiness certification is built and the intelligent cockpit system platform is built by using MATLAB / Simulink and C # mixed programming method, It takes about 320s to complete a final approach mission,and the simulation time on PC can be shortened to 20s or even shorter. Therefore, the invention can generate a large amount of verified and reliable flight sample data in a short time, which is feasible and improves the operation efficiency and reliability of the system. The validity and accuracy of the intelligent cockpit system are verified by comparing the flight data generated by the real flight crew in the highly simulated cockpit system with the flight data generated by the autopilot in the intelligent cockpit system.

Description

technical field [0001] The invention relates to a technology in the field of aviation system control, in particular to a method for realizing an intelligent cockpit system used for civil aircraft design and airworthiness certification. Background technique [0002] Flight safety is an eternal theme in the field of civil aviation. Every civil aircraft must pass the airworthiness certification and obtain an airworthiness certificate before it can perform civil aviation missions. The Civil Aviation Regulations of China (CCAR) proposes the minimum flight crew criterion, which decomposes the tasks of the flight crew into task requirements related to the operation to verify the airworthiness of the aircraft. [0003] [0004] [0005] [0006] The intelligent cockpit system describes the dynamic relationship between the crew, the aircraft and the environment, and is the only interface for human-computer interaction in the aircraft system. Designing and developing an inte...
