Abstract:

According to the current flight test mission for the new flight test requirements, first,introduce the composition and characteristics of several typical Flight-test Measurement System abroad. Second, for the application of new technology, the architecture of Flight-test Measurement System is analyzed, focusing on the new testing techniques and standards currently used and describing the key technology to be focused in the system design and implementation. Finally, illustrates the network of a certain aircraft flight test system, with switching topology, 60 Mbit/s actual bandwidth and time synchronization accuracy of 200 nanoseconds, meet the needs of the flight test task. 
