BEIJING, March 5 (Xinhua) -- China on Friday successfully conducted a trial run on a 500-tonne-thrust liquid oxygen (LOX) and kerosene rocket engine, according to the China Aerospace Science and Technology Corporation (CASC).

It marks a new breakthrough in the country's rocket-engine technologies, and will lay a solid foundation for its follow-up development of the heavy-lift carrier rocket, said the developer.

The new engine, with its design and management fully digitalized, provides three times the thrust of a 120-tonne-thrust LOX kerosene high-pressure staged combustion engine, the CASC said, adding that its comprehensive performance indicators are equal to the best in the world.
