摘要
对一类气囊内外压差恒定的平流层软式飞艇,在考虑大气密度、温度变化以及大气风场的基础上,建立了飞艇三维空间运动的动力学模型;并针对能量消耗最少和航行时间最短两个指标函数,利用高斯伪谱法设计了飞艇从平流层返回地面的航迹,并对飞艇飞行高度、速度以及推力等状态变化进行分析研究.
The 3-D space motion dynamic model of a class of airship with constant pressure is presented. Based on the shortest time and the minimum fuel consumption, its route from stratospheric to the ground is designed. In the constructed model and route planning, the atmospheric density, temperature and wind field are considered. The states of the airship, like height, speed, power are also analyzed.
