Chinese space engineers have carried out the first ignition test of the world’s most powerful solid propellant rocket engine, which will be used on next-generation rockets, according to the Xi’an Academy of Solid Propulsion Aerospace Technology. in Shaanxi province.
The academy, a subsidiary of the public space giant China Aerospace Science and Technology Corp, announced Tuesday afternoon that a test had been concluded this morning.
The engine has a diameter of 3.5 meters, 150 tons of solid propellant and a thrust power of 500 tons, making it the most powerful and fuel efficient integrated solid rocket engine in the world, has the academy said in a statement, noting that the test took place at an engine testing facility in Xi’an.
Wang Jianru, chief engine designer, said that it incorporates a number of advanced technologies and high-performance composite materials and has world-class capabilities.
“The success of the test means that we have made substantial progress in improving the capacity of our solid propellant carrier rockets. It also laid the foundation for our research and development of a 1000 ton thrust engine.” he said, noting that new engines are needed for China to build super-heavy rockets.
âCurrently, our large solid rocket motors still lag behind some foreign models and cannot serve the country’s goal of building next-generation rockets,â Wang said. âTherefore, we have been working hard on the technologies required for large diameter powerful solid rocket engines. “
Xi’an Academy researchers have started to design a variant based on the 500-ton thrust type, Wang said, explaining that the variant will be used on the super-heavy rocket being developed by Chinese engineers. .
Researchers at the Chinese Academy of Launcher Technology in Beijing, another subsidiary of CASC, are designing a super-heavy rocket, the Long March 9, which will likely become one of the largest and most powerful launchers in the world.
The rocket is expected to enter service around 2030. It will be 93 meters high and will have a takeoff weight of 4,140 tonnes and a thrust of 5,760 tonnes. The diameter of its main stage will be around 10 meters, according to the designers.
The craft will be so powerful that it will be able to transport spacecraft with a combined weight of 140 tons to low earth orbit hundreds of kilometers above the ground, and will also be able to deploy spacecraft weighing up to 50 tonnes on Earth. – lunar transfer trajectory for lunar expeditions.
