Chinese Developer Completes Delivery of Liqing 2 Rocket Engine

China’s CAS Space Delivers Powerful Liqing-2 Rocket Engine

China’s commercial spaceflight company, CAS Space, has announced the completion and delivery of the Liqing-2 rocket engine, marking a significant step forward in the nation’s space technology.

The Liqing-2 is a liquid oxygen kerosene engine with a thrust capability of 110 tonnes. According to CAS Space, the engine utilizes pin injection technology in both its gas generator and thrust chamber. This technology is implemented in the first-stage engine of the company’s Lijian series rockets.

One of the notable features of the Liqing-2 engine is its adjustable thrust ratio, ranging from 50% to 100%. This flexibility allows for enhanced control during rocket launches. The ground thrust of the engine can reach an impressive 110 tonnes.

The development project for the Liqing-2 engine was approved in the second quarter of 2022, with production commencing in the first quarter of 2023. Early this year, the engine successfully completed a series of liquid flow tests, assembly procedures, and delivery reviews, leading to its final delivery.

The Lijian-1 series rockets, powered by engines like the Liqing-2, have been instrumental in China’s commercial space missions. To date, they have successfully launched a total of 57 satellites across five flight missions, contributing significantly to the nation’s space exploration and satellite deployment efforts.

CAS Space, established by the Institute of Mechanics under the Chinese Academy of Sciences, continues to play a pivotal role in advancing China’s commercial spaceflight capabilities. The successful delivery of the Liqing-2 engine underscores the rapid progress and innovation within China’s aerospace industry.
