摘　　要：民用飞机轮速传感器是飞机刹车系统的关键设备,用于刹车系统的防滑控制,防止刹车过程中机轮深度打滑和锁死。简要介绍了国外飞机轮速传感器随防滑刹车系统的发展历史,从工作原理和结构形式等方面阐述了变磁阻式、直流式、霍尔式和光电式四种类型的轮速传感器。目前主流民用飞机(包括A320、A330和波音737、波音747、波音777等机型)均采用变磁阻式轮速传感器,其产品形式多样,属于较为成熟的产品;波音787飞机在大型民用客机上采用了霍尔式轮速传感器,其具有体积小重量轻,响应速度快的优势,具有较好的应用前景;公开资料显示,直流式轮速传感器结构复杂、可靠性较低,在协和号飞机上有应用;光电式轮速传感器对振动环境等要求较高,当前技术水平无法满足机轮处恶劣的振动环境,目前尚无装机产品。The civil aircraft wheel speed transducer is one of the key equipments in the aircraft brake system,used for anti-skid control of the brake system,to prevent the wheel skid and lock in the process of braking.This paper briefly introduces the development history of foreign aircraft wheel speed transducers with anti-skid braking system,and expounds four types of wheel speed transducers,namely variable reluctance type,direct-current type,hall type and photoelectric type,from aspects of working principle and structure.At present,the mainstream civil aircrafts(including A320,A330 and Boeing 737,Boeing 747,Boeing 777 and other models)all adopt the variable reluctance wheel speed transducer,which has diverse product forms and is a matured product.Hall type wheel speed transducer with the advantages of small size,light weight and fast response speed,is used in Boeing 787 civil aircraft,and it has a good application prospect.According to the public data,the direct-current wheel speed transducer is used in the Concorde aircraft but its complex structure and low reliability handicap its application.The photoelectric wheel speed transducer requires low vibration,and the current technology can not meet the harsh environment of the wheel,so there is no installed product at present.
