本文研究空间飞行器在制动火箭作用下从运行轨道过渡到返回轨道的运动。本文给出了飞行器的质心运动方程解析解的表达式,并利用该解析解给出确定制动火箭的制动速度和制动方向的简单计算公式及计算实例。一、前言空间飞行器从运行轨道返回地面时,要用制动火箭将飞行器减速,使飞行器脱离运行轨道后才能返回地面。制动火箭对飞行器的作用和三个参数有关:制动速度、制动方向和制动
This paper studies the movement of the spacecraft from the orbit to the return orbit under the action of the brake rocket. In this paper, the expression of analytic solution of the mass center motion equation of the aircraft is given and a simple calculation formula and a calculation example are given to determine the braking speed and braking direction of the rocket using the analytical solution. I. INTRODUCTION When a spacecraft returns from the orbit to the ground, it uses the rocket to decelerate the aircraft so that the aircraft can be released from the orbit to return to the ground. Brake rocket effects on the aircraft and the three parameters: braking speed, braking direction and braking
