平流层飞艇是一个复杂的系统。飞艇的参数估算及飞行控制是其设计过程中很重要的关键环节。本文依据飞艇体积和重量的耦合关系对其部分参数进行了估算，设计了飞艇的概念模型。针对给出的飞艇模型，基于内外压差保持一致，建立了飞艇放飞和回收过程的充放气模型，并对该模型进行了仿真分析。仿真结果表明，飞艇的飞行速度、高度和气囊温度等对充放气速率有很大影响。
平流層飛艇是一箇複雜的繫統。飛艇的參數估算及飛行控製是其設計過程中很重要的關鍵環節。本文依據飛艇體積和重量的耦閤關繫對其部分參數進行瞭估算，設計瞭飛艇的概唸模型。針對給齣的飛艇模型，基于內外壓差保持一緻，建立瞭飛艇放飛和迴收過程的充放氣模型，併對該模型進行瞭倣真分析。倣真結果錶明，飛艇的飛行速度、高度和氣囊溫度等對充放氣速率有很大影響。

Stratospheric airship is a complicated system. Parameters estimation and flight control are two important sides in the designation of stratospheric airship. According to the coupled relationship between volume and mass of stratospheric airship, partial parameters were estimated, and a conceptual model of stratospheric airship was established on the basis of these parameters. According to the model established, based on the consistency of pressure difference between internal and external of stratospheric airship,a model of charging and discharging air in the period of ascent and descent was established and simulated. The result shows that the temperature of bal-lonet and the height and speed of flying have great influence on the velocity of charging and discharging air.
