中文摘要:

      为了开展直升机旋翼实时调整技术（In-Flight Tuning，IFT）研究和产品研制，开发了一套地面维护处理系统。它具有工作流程控制、数据采集与监测、在线实时调整、数据分析和健康监测功能。同时针对飞行系统数据传输稳定性、多种独立的业务数据同步问题，设计了一种基于时间的业务数据同步方法，并采用多线程技术优化数据处理。经旋翼塔试验验证，本系统软件运行稳定，实时调整方法能够有效降低旋翼系统振动。

英文摘要:

      On the basis of the current method of direct calibration of electric axis parameters for tracking precision orbit targets,taking full advantage of BeiDou satellites that are abundant,evenly distributed and with different orbital periods satellites,the efficiency of USB shafting parameter calibration is improved by reasonably designing the scheme of USB tracking BeiDou satellite.The experimental results show that the scheme can effectively overcome the adverse conditions such as weather influence on USB shafting parameter calibration and time limit on tracking low orbit calibration star,and realize the rapid calibration of USB shafting parameters.The calibration results can meet the requirements of USB angle measurement.
