摘　　要：根据对流层大气参数变化特点,利用热力学、空气静力学原理,对飞艇净浮力进行了理论模型计算,并通过仿真分析,总结出压力高度随地面充氦体积比例变化成近似线性递减关系,净浮力不随海拔高度变化、而随地面充氦体积比例变化成近似线性递增关系,净浮力随压力高度变化成近似线性递减关系,净浮力随飞艇囊体体积变化成近似线性递增关系以及不同大气条件下的相关变化规律。该问题的研究,旨在用于指导对流层飞艇囊体体积的设计,并可作为飞艇地面维护保障工作的理论依据。According to the change in troposphere atmosphere parameters, the theoretical model computation was made for the airship net-buoyancy by using thermodynamics and aerostatics principles. Based on the simulation analysis, this paper summarized approximate linear decreasing relations of the pressure altitude change along with the ground helium volume proportion, the approximate linear in- creasing relations of the net-buoyancy change along with the ground helium volume proportion, the approximate linear decreasing relations along with the pressure altitude variation, but not the altitude change, the approximate linear increasing relations of the net-buoyancy change along with the airship pouch body change in volume, and the related change rule in the different atmospheric conditions. The research on this problem is for the purpose of using to instruct the design of the troposphere airship pouch body volume, and can be used as the theoretical basis for the airship maintenance and protection work of the ground.
