| Abstract: | In this paper,an analytic calculation method for mass and inertia characteristics of a class of stratospheric airship with double semi-ellipsoid shape is proposed according to proper assumptions.Variation curves of airship＇s mass,position of mass center and inertia are given by simulating airship＇s rising process.The rationality of this method is demonstrated based on theoretical analysis.At last,the influence of the airship＇s mass and inertia characteristics on its stability and controllability are briefly analyzed. |
