摘　　要：无人机液压弹射器制动系统包括绳轮制动系统、滑车缓冲系统两个制动分系统。详细叙述了两个制动分系统的结构设计方案及其工作原理,理论分析其制动效果后通过试验验证了该系统的可行性,最终得出无人机液压弹射器制动系统结构紧凑、性能稳定、安全可靠,并且可以在无人机弹射起飞后的瞬间将滑行小车成功制动。另外,研究成果即将应用于实际生产,并为相关研究提供理论依据。The brake system of UAV hydraulic catapults includes two brake subsystems： a sheave brake system and a pulley buffer system. This paper describes the structural design scheme the working principle of the two brake subsystems in detail. By the theoretical analysis of the braking verifying the feasibility by trial,we obtain the results that the break system is compact、stable performance and reliable,and it can break the pulley in a instant after unmanned aircraft take-off. In addition,the research results will be applied to practical production,and provide a theoretical basis for other types of ejection system＇s design.
