China's self-developed solid rocket engine with the world's largest thrust had a successful test run Tuesday, marking a substantial improvement to the payload of the country's solid propellant rockets.
The booster engine, with a diameter of 3.5 meters and a maximum thrust of 500 tons powered by 150 tons of solid fuel, is the most powerful solid rocket engine with the largest thrust in the world so far.
Multiple cutting-edge technologies, for example, a high-performance fiber composite shell, an integral-casting combustion chamber of high load and an oversized nozzle, make it a world-leading rocket engine.
"Today's testing is very successful. We have tested all the parameters including the 500-ton thrust that worked 115 seconds," said Ren Quanbin, president of the Fourth Research Institute of China Aerospace Science and Technology Corporation (CASC), the developer.
Different from a liquid-fueled engine, a solid rocket engine is powered by high-energy gunpowder, with the advantages of simple structure, flexible mobility and large instantaneous thrust.
"For solid rocket engines, the gunpowder load was several hundred kilograms, several tons or dozens of tons. This is the first time to surpass 100 tons," said Yu Ying, head of the 7416 plant under the Fourth Research Institute.
The successful test run offers more power options for the development of carrier rockets, and is of great significance in promoting the development of the country's large and heavy rockets.
Based on the newly-tested booster engine, its developer has begun the study of the five-stage booster engine, of which the diameter can reach 3.5 meters and the thrust can reach 1,000 tons.
The future booster engine is expected to be used in large and heavy rockets to meet various demands for launch vehicles during space missions like manned Moon landings and deep space exploration.
"We are at the international advanced level in the field of large solid rocket engines. Next, we will develop 1,000-ton solid rocket engine to provide stronger thrust for China's carrier rockets in the future," said Ren.
