摘要
针对风切变对民用飞机起飞阶段恶劣影响这一瓶颈性问题,设计开发了一个基于MATLAB虚拟现实环境的民用飞机三维可视化仿真平台。通过建立微下击暴流、过山气流和大气紊流的风场模型,分析复杂风切变对民用飞机起飞的影响,并给出相应的影响公式。利用MATLAB Simulink良好的开放性和扩展性,搭建了基于符号控制的民用飞机控制系统,开发了风切变的民机起飞三维可视化仿真软件。数字仿真实验验证了该方法的可行性和有效性。
Focusing on the problem of wind shear disturbance during the taking off procedure of civil aircrafts , a MATLAB based three-dimensional visual simulation platform has been developed .Based on the description of the models of microburst , mountain airflow and turbulence , the influences of complex wind shear during taking off are analyzed , and the related equations are also deduced .The symbolic control-based flight control system for taking off in the wind shear is designed .Taking advantages of the expansibility and open character of the MATLAB Simulink , an interactive software is also developed .Experimental results verified the feasibility and effectiveness of our devel-oped platform .
