摘要
针对当前飞行试验任务下新的试飞测试需求,首先介绍了国外几种典型的试飞测试系统组成及其特点;其次,针对新技术的应用,对试飞测试系统的系统架构进行了分析,重点介绍了目前采用的新的测试技术和标准,对新系统的设计、实施方案中需重点关注的关键技术环节进行了阐述;最后,例举了某型飞机网络化的试飞测试系统,以交换式的拓扑结构,60Mbit/s的实际带宽和200ns的时间同步精度,满足了飞行试验测试任务的需求。
According to the current flight test mission for the new flight test requirements, first, introduce the composition and charac- teristics of several typical Flight--test Measurement System abroad. Second, for the application of new technology, the architecture of Flight --test Measurement System is an^tlyzed, focusing on the new testing techniques and standards currently used and describing the key technolo- gy to be focused in the system design and implementation. Finally, illustrates the network of a certain aircraft flight test system, with switc- hing topology, 60 Mbit/s actual bandwidth and time synchronization accuracy of 200 nanoseconds, meet the needs of the flight test task.
