捷龙一号首飞（英文）

The Smart Dragon 1(SD-1) launch vehicle is the first commercial rocket developed by China Academy of Launch Vehicle Technology(CALT), targeting to the international launch market for small satellites. As the smallest launch vehicle in China at present, SD-1 is one of the most efficient solid boost rockets nationwide in terms of launch capacity. Compared with current domestic rockets, it provides remarkable access to space with a faster response, higher orbit-injection accuracy and better payload accommodation at a lower cost. On August 17, 2019, SD-1 completed its maiden flight and delivered three satellites into the desired Sun Synchronous Orbit(SSO) of 550 km accurately. In this article, a technical review of SD-1 is presented detailing the design concept and the use of state of the art technology throughout its development.

新一代运载火箭自主控制技术（英文）

This paper introduces the autonomous control technologies for a new generation launch vehicle for guidance and attitude control. Based on the iterative guidance mode(IGM) of Long March launch vehicles, the autonomous compensation IGM(ACIGM) for the terminal attitude deviation during the coasting phase is proposed. Considering the characteristics of large static instability and weak bearing capacity, the attitude control technology based on active disturbance rejection control(ADRC) and a control method based on an accelerometer are proposed. Targeting at non-fatal failures that may occur during flights, autonomous guidance reconstruction technology, nozzle fault diagnosis and reconstruction technology in the coasting phase are studied. Some of the autonomous control technologies proposed in this paper have achieved good control results as seen through flight verification.
