- Abstract
In 2018, China's launch vehicles completed 37 launches, including the Beidou Project and the Chang'e IV mission. Private spaceflight also completed several attempts to launch rockets. In the past, the development of launch vehicles has always been based on high reliability, and the cost of development is often ignored. However, in the increasingly fierce competition in the international and domestic commercial launch market, how to reduce the cost of launch vehicles has been considered seriously by all countries. Control system plays a very important role in launch vehicles, and launch vehicle control system in China has made the following improvements in cost control from the following aspects. 1. Establishing control system architecture and giving priority to the use of product-based products; 2. Optimizing system redundancy scheme, reducing system complexity and reducing product types and quantity; 3. Integrative design of test launch control system integrating similar functions such as distribution, control, testing and communication in product and system level; 4. Development and use of advanced tools to improve production efficiency, test reliability and test efficiency reduces personnel, process and time; 5. Improvement in production process, components, and materials reduce costs without reducing reliability. 6. Research on reusable launch vehicle Through the improvements above, the development cost of launch vehicle control system has been greatly reduced in LM-2C, LM-3A series, LM-7 and other models, making it possible to enter space at low cost. In 2019, China will complete the 300th launch mission in the history of launch vehicles. In the future, China will also provide the world with more reliable and cheaper launch vehicles.
