摘　　要：针对软式飞艇,在确定压力高度和囊体体积的条件下,对其所受的浮升力随高度变化规律进行了理论分析和仿真计算,给出了飞艇囊体体积设计、压力高度的确定与总浮升力和静浮升力各参数之间的数值变化关系,为飞艇的总体设计提供了理论基础。Airship is ＂aerostat＂ with air buoyancy. The uplift is related to the amount of practical payload which the airship carries and thus has an important effect on the flight height. Under the conditions of determining the pressure height and ballonet volume, the theoretical analysis and simulation calculation are made of the variations in the uplift of the blimp when there is change in height. The numeric relations obtained about the parameters of the airship provide a theoretical basis for the general designof the airship.
