基于FlightGear的飞行数据管理与分析系统

Management and Analysis System for Flight Data Based on FlightGear

飞行器是一个庞大的复杂系统,其设计与开发需要几轮迭代,而仿真技术在此过程中起着无法替代的作用。开源仿真软件FlightGear主要用于飞行模拟,并不能用于飞行器的系统研发仿真与验证。本文以FlightGear为基础,对其进行了扩展,从而实现了一套集飞行数据管理和分析于一体的软件系统。利用FlightGear接口,开发了以数据采集为主的通信、存储等模块,使扩展系统能够实时、灵活地采集飞行器的参数,并存储于数据库;设计并实现了用于飞行器姿态预测的分析模块,新预测方法提高了姿态参数的预测精度。目前,该扩展系统已用于某飞行器的研发论证中,取得了较好的经济效益。

Aircraft is a large complex system,and the development of aircraft system requires several rounds of iteration.The simulation technology plays an irreplaceable role in the process.FlightGear,an open source simulation software,is used for flight simulation.However,it cannot be directly used in aircraft system research and development of simulation and verification.A set of software system combined flight data management and analysis is presented based on FlightGear.In order to collect real-time flight parameters flexibly and store them in database,the system expands and develops storage and communication modules for data collection,thus making the full use of the interfaces of FlightGear.The system designs and implements analysis module for predicting attitude of aircraft,and improves the prediction accuracy of posture parameters.At present,the extended system has been applied in research and demonstration of aircraft system and has achieved good economic benefits.
