地球同步卫星内部,都装有将卫星最后送入地球同步轨道的远地点发动机(以下简称发动机).该发动机有固体火箭和液体火箭两类,目前各国地球同步卫星所使用的发动机绝大多数都是固体火箭发动机. 本文将讨论同步卫星对国体发动机的总体设计要求,其中最主要的要求是速度增量,其次是外形尺寸和对接设计、推力值和推力偏斜、质量特性、力学环境以及热真空环境等.
Geostationary satellites are equipped with apogee engines (hereinafter referred to as engines) that ultimately send the satellites to the geostationary orbit. The engine has two types, solid rockets and liquid rockets. At present, most geostationary satellites use engines of most countries are Solid rocket motor.This article will discuss the overall design requirements of the national body of a synchronous satellite, of which the most important is the speed increase, followed by the dimensions and the docking design, the thrust value and thrust deflection, the quality characteristics, the mechanical environment and the thermal vacuum Environment and so on.
