摘要
针对一类具有双拼椭球体外形的平流层飞艇,根据适当假设,给出该类飞艇质量和惯量特性的解析计算方法.以飞艇上升过程为例,通过仿真计算给出该过程飞艇质量、质心位置和转动惯量的变化曲线,结合理论分析,验证该计算方法的合理性.最后,简要分析了质量和惯量特性变化对飞艇运动稳定性和能控性的影响.
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.
