摘要
介绍了俄罗斯Fregat上面级的基本功能、组成和主要技术指标。给出了其几何布置、贮箱可承力、独立性与自主性、液-固耦合及大幅晃动和多次起动等特点与关键技术等。给出了2003年欧空局火星探测项目、2005年欧空局金星探测项目和中俄联合火星探测项目等典型应用。
The general function, composition and main features of Fregat, Russian upper stage, were introduced in this paper. The key technologies of geometry deployment, bearable force of the tank, independence and autonomous, liquid-solid coupling and large sloshing, and multiply start were presented. The typical applications such as 2003 Mars exploration of ESA, 2005 Venus exploration of ESA and Mars exploration of China and Russian jointed were given out.
