摘要
在研究临近空间浮空器的过程中,设计了一种低空实验飞艇。为了评价该飞艇的稳定性和操纵性,建立了飞艇的六自由度运动方程数学模型,使用Matlab/Simulink软件完成了飞艇飞行仿真软件设计。另外采用Flightgear作为飞行仿真视景软件,设计飞行仿真软件驱动视景软件的网络接口程序。利用飞行仿真软件,进行了该低空飞艇运动的仿真验证。仿真结果表明,软件达到了预定的设计目标,该实验飞艇方案可行,安定面和推进动力配置基本合理。
Although the description of motion model for aircraft is very perfect, the description of motion model for airships is not yet mature because the difference between them is that the latter sustains forces of the buoyancy and virtual mass inertial, and the corresponding moments. In the development of near space aerostats（ high altitude airship）, a low altitude verifying airship is designed. It is presented that the buoyancy model, the mass model changing with flight altitude, virtual mass inertial forces model and the motion equation model influenced by the buoyancy and virtual mass for the airship. On the basis of model for six degrees of freedom motion equations, the airships flight simulation software is designed by using Matlab/Simulink. The Flightgear software is applied as the vision system. The network interface program to drive the vision system is designed. The low altitude verifying airship is taken as an example, and the flight simulation verification of the airship is carried out preliminarily. The resuits shows that the simulation software reaches its preset requirement, and scheme of the verifying airship is feasible, the configuration of its stabilization and propulsion is rational.
