攻击直升飞机通信导航识别系统的分布式综合模块化航空电子设备综合技术研究

Study on DIMA Integrated Techniques for Communication Navigation Identification System of Attack Helicopter

介绍了以AH-64D阿帕奇为代表的攻击直升飞机通信导航识别(CNI)系统,分析了基于时间触发的分布式综合模块化航空电子设备(DIMA)的结构,构建了一种基于DIMA和公共对象请求代理体系结构(CORBA)逻辑软总线的CNI系统结构.结果表明,通过构建分布式CNI系统结构和高容错的通信网络,可实现支持抵近射频前端的通信资源高度综合,适用于攻击直升飞机自然散热的装机环境,满足故障快速隔离的维护需求.

The communication-navigation-identification （CNI） system of attack helicopter represented by AH-64D ＂Apache＂ was introduced. The distributed integrated modular avionics （DIMA） architecture based on time triggered mechanism was analyzed. An architecture of CNI system based on DIMA architecture and common object request broker architecture （CORBA） logical software bus technology was built. The results show that this architecture achieves to support high integration of communication resources which are close to RF front-end by building distributed system architecture and high fault tolerance communication network, adapts to natural cooling condition for attack helicopter, and meets the maintenance requirements of rapid fault propagation.
