【摘要】 本文根据民用飞机巡航段四维制导[1]的特点,设计了飞机的自动飞行模态[3],并利用模态切换[2]的方法实现飞机巡航段四维制导。仿真结果表明,本文提出的制导方法达到了四维制导的要求,可以实现临时产生的飞行计划,当预测到指定时间无法到达时,可以通过改变加速满足时间要求,且算法可以抑制风的干扰。与目前国内外的其他制导算法相比,本文算法实现简单,适合工程应用。更多还原

【Abstract】 Thinking of the characteristic of 4D guidance in civil aircraft cruise,the paper used a method called multi-mode switching,to realize the flight guidance.First of all,we designed different automatic flight modes used in cruise flight,and then choose one mode in the flight course,when the need changes,it will switch to a different mode.The example of the cruise stage guidance was studied.Simulation results illustrated that the proposed method can satisfied 4Dguidance requirement.The algorithm can follow the flight plan calculated before takeoff,meet the time limits,and suppress the perturbation of winds.Compared with other methods,it was easily realized,and fit for engineering project.更多还原
