Using fluent software , calculate the aerodynamic parameter of projectile and sabot . 3 ) . according to motion equations of sabot and parameter obtained above , calculate and analysis flying motion variety of sabot 3 )利用fluent软件计算得出的弹托气动力参数，运用弹托的运动方程，计算并分析30mm脱壳穿甲弹的弹托飞行运动变化规徘。
Compared with non - slung - load flight , additional aerodynamic load , gravity load should be considered in the slung - load system . so the moment to the gravity center , flight mode and the natural frequency will change 直升机吊挂飞行,与直升机非吊挂飞行状态相比,增加了新的气动载荷、重力载荷,和因此产生的对直升机重心的力矩,其飞行运动模式、低频振荡固有频率均发生改变。
The paper bases on the existing semi - physical real - time simulation environment for flight control system ( fcs ) of unmanned aerial vehicle ( uav ) , aims at the actuality of the output in data and curve form of the system , bases on the theory of the visualization , uses the technique of the modeling , the system running , the model driving and the data communication , designs and achieves the scene graph system based on the real - time simulation system , that could show the real - time flight process of uav and provides the truth for researching the flight rule of uav 本文在现有无人机飞行控制系统半物理实时仿真环境的基础上,针对目前该仿真环境的仿真结果以数据和曲线方式显示的现状,借助可视化技术的相关理论,综合运用模型构造、系统运行、模型驱动和数据传输的一系列技术,设计实现基于该环境的视景系统,实时动态再现无人机飞行运动全过程,为研究无人机飞行运动规律提供直观的事实根据。
