摘　　要：提出了时间触发以太网(Time-Triggered Ethernet,TTE)在运载火箭控制系统中的应用设想。首先介绍了TTE,从通信机制、时间同步、实时性与容错性等方面分析了TTE在火箭控制系统应用中的优势。针对火箭控制系统的功能组成,提出一种基于TTE的双通道冗余总线拓扑结构,分析了基于TTE的控制系统总线数据流。对TTE在运载火箭中的应用进行了探索,可为TTE在航天领域的研究与应用提供借鉴。The idea of rITE applied to launch vehicle control system is introduced. Firsty, rITE technology is introduced, and the advantages are studied for vehicle application and the characteristics of TTE in the view of the mechanism of network communication, time synchronization, real-time and fault-tolerant performance. According to the function and component of the launch vehicle control system, a kind of dual - channel redundant bus topology based on TrE is designed and the data flow of launch vehicle control system based on TTE is analyzed. The result of the paper can not only shows the TTE exploration in launch vehicle application, but also provides a guideline for TTE research in the field of space application.
