China has test-launched a huge new solid rocket motor, creating more propulsion options for the country’s growing space activities.
NS rocket The motor was ignited on Tuesday (October 19) near Xi’an in northern China, igniting for 115 seconds, creating tremendous traces of flames and exhaust.
The new motor was developed by the Academy of Aerospace Solid Propulsion Technology (AASPT), which belongs to China Aerospace Science and Technology Corporation (CASC), the country’s leading space contractor.
The motor is 11.48 feet (3.5 meters) 1 in diameter, has a maximum thrust of 1,000,000 pounds (500 tons) and is powered by 330,000 pounds (150 tons) of solid fuel. NS CASC statement It was said to be the most powerful solid rocket motor with the largest thrust in the world so far.

According to CASC, several cutting-edge technologies such as a high-performance fiber composite shell, an integrated casting combustion chamber, and an oversized nozzle have been demonstrated to make it an advanced rocket engine.
“The test was very successful. We tested all the parameters, including 500 tonnes of thrust that worked in 115 seconds,” said Ren Quanbin, president of AASPT.
“We are at an internationally advanced level in the field of large solid rocket engines. Next, we will develop a 1,000 ton solid rocket engine to provide stronger thrust for Chinese carrier rockets in the future.” Ren said. CCTV..
According to CASC, rocket motors are expected to be used with heavy-duty rockets to meet the various demands of rockets in space missions such as lunar landing and deep space exploration.China is already under development Long March 9 And another Large rocket for launching astronauts For crew lunar missions, neither includes solid rocket boosters.
China has made great strides in recent years, including the successful development and launch of solid propellant rockets. Long March 11, Can be started From land or Sea.. AASPT too Tested A solid engine with a diameter (3.2 m) in December 2020.
However, the new engine is much larger and can be added to launch a rocket to generate additional thrust. It can also be used with China Rocket, a commercial spin-off of CASC. Jielong Solid rocket For launching commercial satellites.
China is also planning the launch of the first rocket, which combines a liquid propellant core stage with a solid side booster. NS Long March 6 It may be released by the end of the year.
Another giant Chinese state-owned company, similar to CASC, with its own space orientation, CASIC, is also developing on a small and large scale. Solid rocket..
This happens when many countries and companies, including China itself, are developing reusable liquid propellant rockets. After the first stage is done, the engines of these new launchers can be reignited to return the first stage to the landing area and burn again for powered descent and vertical landing. In this way, the rocket can be recovered and reused, reducing launch costs.
However, solid rockets cannot be controlled in the same way, and once ignited, they burn until all propellants are exhausted. However, they are simpler than liquid rockets and offer unique advantages in cost and production.
China’s new solid rocket motor But it’s also not the largest or most powerful solid fuel engine ever tested. Aerojet was developed in the 1960s and Test dismissal SL-260. “260” stands for inch diameter, or 21.60 feet (6.60 m).
It was designed to demonstrate the potential of NASA to utilize large-scale SRMs for space exploration, but was never used.
