摘要
随着现代飞机的不断发展,尤其是大型飞机的发展,飞行试验要求测试的参数种类和数量越来越多,数据传输量越来越大。为了满足新一代飞机试飞快速发展的测试需求,构建网络化机栽测试系统,实现测试系统间数据的海量传输,各个子系统之间的交互以及网络数据融合是一个发展的趋势。但是在一个大型的机载网络测试系统设计中,如何考虑测试系统测试参数的实时性、同步性和可靠性是试飞测试工程师将面临的全新挑战。
As the development of the modern aircraft,especially the jumbo aircraft,the varieties and quantities of the test parameters have been increasing dramatically.It＇s the same to the capacity of the data transmission. To meet the demands of rapid development of flight test for a new generation of aircrafts,it＇s a trend to build a networked measurement system so as to achieve transmission of mass data,interaction among each subsystem and fusion of networked data.But how to insure the real-time,synchronization and reliability of the test parameters is a new challenge for flight test engineers,when designing a huge airborne networked measurement system.
