在方向不变的惯性坐标系建立和求解弹道式火箭的动力学方程,可以不考虑牵连惯性力和科氏惯性力,把惯性制导建立在更简捷明了的基础上。不同于过去书刊常常在随地球一起转动的坐标系中研究飞行力学的各种问题。阐明了火箭离开地球表面起飞的初始条件,详细分析了被地球引力吸住一起转动的空气或大气作用在惯性空间运动着的火箭上的空气动力的处理方法。推导了用惯性坐标系中火箭的运动参数计算地理位置的公式和动坐标系运动参数的公式。
Establishing and solving the dynamic equations of the ballistic rocket in the invariant inertial coordinate system makes it possible to establish the inertial guidance on a more straightforward basis irrespective of the entrained inertial force and the Coriolis inertia force. Different from the past books and magazines often study the problems of flight mechanics in the coordinate system that rotates with the earth. The initial conditions for the rocket to leave the Earth ’s surface are elucidated. The aerodynamic treatment of the rocket moving in the inertial space by the attraction of the Earth’ s gravity with air or the atmosphere is analyzed in detail. The formula for calculating the geographical position and the kinematic parameters of the kinematic coordinate system are derived from the parameters of the rocket in the inertial coordinate system.
