自20世纪60年代以来，世界各航天强国成功研制多型上面级，并与基础级火箭配合，成功将不同类型的卫星送入预定轨道，其中自旋稳定固体上面级由于其控制方式和动力系统简单而被广泛使用。针对长征二号丙火箭自旋稳定固体上面级的总体结构布局、姿态控制方案、关键技术攻关等3个方面，对研制情况进行介绍。%With independent control and propulsion system, upper stages are added on basic vehicles and featured with strong adaptability on satellites launching missions. Generally after the basic vehicle shuts down, the upper stage will carry S/C and conduct slipping, attitude adjustment,orbit maneuver, payload separation and multi-S/C deployment, etc. Since 1960s, great powers have developed various upper stages that deliver various kinds of S/C to pre-selected orbit successfully. The spin stabilized solid upper stage is widely used by virtue of its simple control and propulsion system. In this paper, some design characters of spin stabilized solid upper stage of CZ-2C will be presented, including its overall structural layout, the gesture control scheme and some key techniques.
