Research on Application Technology of Intelligent Wireless Sensor Network in Flight Test

摘要

Aimed at the problems of many test parameters, complicated lead wires, large additional weight, lack of flexibility and expandability as well as low level of intelligence and networkability of existing aircraft test flight test systems, with the application requirements of intelligent wireless sensor network for flight test technologies as the lead, this paper makes research on key technologies of intelligent wireless sensor network in aircraft flight test, and focuses on the synchronous acquisition system architecture, real-time protection method, and data transmission reliability checking method and the development of acquisition and recording system for wireless sensor networks based on the iNET standard for aircraft flight test. Besides, this paper also performs simulation and engine ground test verification which laid the foundation for the application of intelligent wireless sensor network technology in aircraft flight test.
