The development of dual-mode chemical propulsion systems

In this paper the technical characters, principles of operation and application predominance of dual-mode propulsion system on satellites were reviewed in detail. And its development, present status and the trend of development in the future were summarized and the key techniques were analyzed. The importance and necessity of the investigation on the system were emphasized, and the development strategy and approach on the technique were brought forward. According to our technical base of monopropellant and bipropellant propulsion systems, and the task requirement of satellites on the life, control precision, operation environments, the preliminary idea on design of dual-mode propellant systems was illustrated.
