由于附加质量、浮力作用、重心位置的影响,飞艇的线化方程表达式较飞机复杂,国内外对飞艇稳定分析基本采用数值分析。本文通过推导与简化,给出飞艇侧、航向稳定性分析的简洁公式,阐明了影响侧航向稳定性的主要参数。最后通过示例计算,验证了分析方法的有效性。
Due to the additional mass, the buoyancy effect and the position of the center of gravity, the expression of linearization equation of the airship is more complicated than the aircraft. The numerical analysis of the stability of the airship at home and abroad is basically carried out. In this paper, the concise formulas of stability analysis of airship and heading are given by derivation and simplification, and the main parameters affecting the stability of the lateral heading are clarified. Finally, through the example calculation, the validity of the analysis method is verified.
