摘要
全数字仿真在临近空间飞艇研制过程中起着重要作用。本文以临近空间飞艇为研究目标,首先分析飞艇的受力情况,将体积中心作为艇体坐标系原点建立飞艇动力学方程和运动学方程。综合起飞、降落和巡航中的风场特点,建立可变的风场模型。利用Matlab/simulink软件搭建仿真模型,实现飞艇全数字仿真。最后对仿真结果进行了简要分析。
Full digital simulation plays an important role in the development process of near space airship. Based on near space airship as a research object, the first analysis of stress conditions of airship, the airship volume functions as a dynamic and kinematic equations of the origin of the hull coordinate system. Based on the take-off, landing and cruise of the wind field characteristics, the establishment of wind field model is possible. Simulation model is built by using Matlab/simulink software, realize the airship digital simulation. Finally, the simulation results are analyzed.
