网络化试飞测试系统半实物仿真平台开发设计

面对空间分布更广、被测对象更多、系统功能更复杂的测试要求,民用飞机试飞测试多采用网络化测试系统架构,然而因为网络技术本身的特点,网络化测试系统仍然存在实时性、可靠性以及稳定性的问题,针对这些问题,通过构建网络化试飞测试系统半实物仿真平台,模拟网络化试飞测试系统测试数据传输环境,并提出各网络性能参数的监测方法,为网络化试飞测试系统设计及优化提供实验平台及量化数据,从而指导机载测试系统设计,确保测试数据有序可靠地传输.

Design of Semi-Physical Simulation Platform for Networked Flight Test System

To meet the test requirment with a wider spatial distribution,more objects to be tested,more complex system functions,the networked test system is deployed for the flight test of civil aircraft.However,the intrinsic characteristics of network may cause some problems,such as the poor real-time performance,low data transmission reliability and stability.To solve these problems,the semi-physical simulation platform for networked flight test system is built to simulate data transmission network environment of networked flight test system and propose the measurement methods for the network performance metrics,which provides the test platform and data for the design and optimization of networked flight test system to ensure the test data to be transferred controllably and orderly.
