20小扰动理论。奥-索末非方程。 - In this thesis , different types of stability equations , including orr - sommerfeld equation ( ose ) and parabolized stability equation ( pse ) based on the “ slow change ” hypothesis and the local method equation which is computed in local range , are derived from navier - stokes equation with “ small disturbance ” hypothesis
本文从navier - stokes方程出发,导出不同形式的流动稳定性方程,包括采用小扰动理论得到的orr - sommerfeld方程( ose ) 、基于流向慢变特性而得到的抛物化稳定性方程( pse )以及在一小范围内计算的局部法方程。 - The forces and moments acting on the bomb are analyzed and the corresponding reference frames and motion model are built . based on disturbance theory , the mathematical model is simplified . what ' s more , taking real flight of the sgb into account , some assumptions are given . on the basis of these assumptions , the motion of the sgb is broke into the motion in vertical plane and the motion in the horizontal plane . dynamic characteristics of the motion in vertical plane is mainly studied
在此基础上，通过小扰动理论将简易制导航弹的空间运动数学模型化简，得到简易制导航弹的空间扰动运动数学模型。根据简易制导航弹的实际飞行情况，作出了一些假设条件，将简易制导航弹的空间扰动运动分解成纵向扰动运动和侧向扰动运动，并相应的得到两个通道的数学模型。
