本文采用描述飞机空间机动飞行的五自由度简化方程,在操纵参数空间内对不同过载下的飞机机动飞行进行了稳定性研究,提出了确保运动稳定的必要条件,分析了非线性气动导数对稳定边界的影响,对线化系统出现零根或纯虚根两种临界情况的稳定性作了进一步的探讨.
In this paper, a simplified five degree of freedom equation describing aircraft maneuver flight is used to study the stability of aircraft maneuver flight under different overload in the maneuvering parameter space. The necessary conditions for ensuring the stability of the maneuver are put forward. The nonlinear aerodynamic derivatives are analyzed for the stability The influence of the boundary conditions on the stability of the two critical cases of zero or pure imaginary root of the linearized system is discussed further.
