China's Liqing-2 rocket engine completes long-range test

China's liquid oxygen kerosene engine, the Liqing-2, developed by CAS Space, completed a long-range test on Thursday, marking a significant milestone in the advancement of reusable rocket technology.

During the test, the 110-tonne pin engine underwent multiple ignitions. The longest single operation lasted 200 seconds, contributing to a total operational time of 420 seconds, which covered the flight duration of the first stage of the rocket. The engine's cumulative testing time has now surpassed 1,000 seconds.

"This marks that the engine can enter the reliability verification testing phase, preparing for mass production," said Chen Zhan, chief designer of the Liqing-2.

The Liqing-2 features a pin nozzle design, incorporating a pin-like protrusion at the center of the engine nozzle. This design allows for precise thrust control through a simple structure, making it highly reliable and an essential technology for reusable rockets. Compared to traditional designs, the Liqing-2 is more cost-effective and lighter, balancing high performance with economic efficiency.

"The pin nozzle injector comes at a relatively low cost. The successful development of this type of rocket engine means that China's commercial aerospace sector will have greater capabilities, more options, and lower costs, contributing to the industry's high-quality growth," said Chen.

The Liqing-2 will serve as the main engine for the reusable rockets Lijian-2 and Kinetica-2H.

CAS Space is a commercial spaceflight company established by the Institute of Mechanics under the Chinese Academy of Sciences.

Nearly 100 guests from the Chinese and American business, academic, and media sectors gathered in New York Friday to discuss new opportunities brought to the world by China's blueprint for high-quality development.

The "China in Springtime: China's Development Opportunities for the World" high-level dialogue, hosted by China Media Group, came after the "two sessions" concluded in Beijing, an event watched closely by many industry leaders in the United States.

Speakers said that as a key window into contemporary China, the annual "two sessions" once again drew global attention. This year's meetings approved important documents, including the Outline of the 15th Five-Year Plan (2026-2030). This roadmap for China's high-quality growth is seen as providing a new list of opportunities for the world.

Participants emphasized that China's development cannot be separated from the world, and global prosperity also requires China. They described this year as significant for China-U.S. relations, calling for a steady, sound, and sustainable development in bilateral ties that benefits both nations and the world.

During the session, guests from the investment and technology sectors explored topics such as the potential for China-U.S. economic and trade cooperation, as well as the global opportunities arising from technological innovation and new quality productive forces.

The event also featured screenings of CMG-produced programs, including an amazing martial arts performance presented by a dozen humanoid robots with young Kungfu artists at the recently staged Spring Festival Gala, China's most-watched TV show.

The dialogue series will be held in countries across Europe, Asia, Africa, the Middle East, and Latin America.
