摘　　要：随着通用航空的发展,对小型飞机及小型航空电子系统的需求越来越大。基于小型综合航电系统的结构与应用需求,通过分析ARINC 615A标准,设计了一个基于TFTP协议的数据与应用加卸载系统架构。针对系统架构中的难点,提出了TFTP协议栈、数据卸载与应用软件加载等三项关键技术,给出了具体的设计与实现方法。系统在Vxworks平台上实现,目前已在某小型综合航电系统项目中取得了较好的工程应用效果。With the development of general aviation, requirements for small airplane and small avionics system become more and more. Based on the framework and application requirements of small avionics system,and by analyzing ARINC 615A standard, it was promoted a data and application loader system framework on TbTP protocol. In accordance with difficulties of the system framework, it was proposed three kernel technologies which were TFTP protocol stack, data downloading and application uploading. Then it was given specific design and realizing method. This system was realized on Vxworks operating system. Now it has been applied on a small avionics system project and gained better engineering application effect.
