Key technologies of high speed aircraft braking system
High-speed aircraft because of its wide speed range,fast time variation,uncertainty and other complex characteristics,compared with traditional aircraft,unique aerodynamic shape,smaller aspect ratio,for high-speed aircraft aerodynamic shape in the horizontal take-off and landing stage of the speed is larger,so the take-off and landing system,especially the brake system put forward more stringent requirements,for the characteristics of the high-speed aircraft brake system,this paper summarizes the development history of aircraft brake systems,and analyzes in detail the technical development of important subsystems of brake systems,such as brake disc materials,actuation methods,and control methods.Based on the working characteristics of high-speed aircraft and the functional characteristics of brake systems,four key technologies for the braking system of high-speed aircraft have been summarized:high-speed brake friction material technology,high-temperature and high-power actuation technology,sensor technology in harsh environments,and intelligent composite control technology.And prospected the development of key technologies.
