Problems solved by technology

At present, the most important problem restricting the development of my country's aircraft flight control actuation system is: in the past, it was mainly imitation, and basically continued the hydraulic system technology of the second-generation aircraft. Although the third-generation aircraft has achieved great success, there is a lack of innovation in subsequent development. Weak technical support, lack of advanced system design concepts and ideas
However, due to the large number of alternatives involved in the design process, it is impractical to consider manual optimization

Abstract

An intelligent design and evaluation method for a flight control actuation system of a large aircraft includes the steps of reducing a configuration set of a flight control actuation system by an artificial intelligence method based on a constraint satisfaction problem according to a constraint condition; according to the safety requirements of the flight control actuation system, eliminating theconfiguration that does not meet the requirements; establishing an evaluation method of a flight control actuation system optimization index; according to the objective function constructed by the evaluation method, carrying out the multi-objective optimization of flight control actuation system, and obtaining a Pareto optimization set to make the configuration set shrink further; carrying out decision analysis for the Pareto optimization set to determine the target configuration of the flight control actuation system.

Description

technical field [0001] The present disclosure relates to an intelligent design and evaluation method for a flight control actuation system of a large aircraft. Background technique [0002] The high-performance and high-reliability flight control actuation system is the most important airborne subsystem related to flight safety, maneuverability and control quality, and is of great significance to the sustainable development goals of the country's large passenger aircraft and large transport aircraft. The main function of the flight control actuation system is to carry out the distribution of secondary energy power transmission and actuation execution, and complete the flight control and manipulation of the aircraft according to the scheduled tasks. But so far, the flight control actuation system of my country's large passenger aircraft is mainly provided by foreign companies such as PARKER and EATON, and its design creation theory and key technologies are not clear. Therefo...
