平流层飞艇飞行温度限和飞行速度限分析

摘要

The flight performance of a stratospheric airship is very important for its flight safety and maneuverability. In this paper, based on the characteristics of stratospheric airship, concepts of " flight temperature limits" ( FTL) and " flight velocity limits" ( FVL) are proposed to evaluate the extreme flight performance. and these estimate methods for FTL and FVL are derived. A concrete analyze results of FTL and FVL for a certain designed stratospheric airship are preaented and discussed.%平流层飞艇的飞行性能对其飞行安全、机动能力等非常重要.本文结合平流层飞艇的特点,提出"飞行温度限"和"飞行速度限"对其极限飞行性能进行评估,并在理论分析的基础上,提出相应的估算方法.通过具体实例,对平流层飞艇的极限飞行性能进行评估.
