November 20, 2020, 20:43, China's new generation of carrier rockets - Long March 5 in China Wenchang space launch site successfully achieved first flight. Suzhou Jufeng as the Long March 5 circulating pump low-temperature motor windings and servo motor materials suppliers are particularly proud of. Long March 5 innovation more difficult, large technical span, high complexity, on behalf of China's carrier rocket technology innovation the highest level. Long five servo system sensorless vector control permanent magnet synchronous motor technology demanding, other materials manufacturers difficult to meet the requirements, Suzhou giant peak insulation system has been assessed to meet the requirements, to solve technical bottlenecks. And the establishment of a dedicated laboratory for the servo motor outside the Association to my unit equipped with full-time technical staff, from dipping to clean every step to do strict requirements strict control. Suzhou Jufeng in the Long March five breakthrough in the process of high-power hydrogen and oxygen engine series of key core technology, provides a long five engine hydrogen oxide fuel environment with ultra-low temperature permanent magnet synchronous motor winding frequency conversion line, the first successful implementation of its mission, China's large thrust non-toxic non-polluting liquid rocket engine blank, rocket carrying capacity ranked first in China, and entered the international advanced ranks. The successful launch of the Long March 5, for the follow-up lunar exploration project three, manned space flight, Mars detection and other major national science and technology projects and the smooth implementation of the project to provide a strong guarantee. As a participant in this event, the long five successful fly to inspire Jufeng people in the insulation system research on the confidence and determination!
       In the active long-range series of launch rockets family, the Long March 5 is worthy of the name of the big man, the astronauts affectionately called it fat five: it is 57 meters tall, the equivalent of 20 storey; waist thickest, Secondary diameter of 5 meters, the waist is also tied with four 3.35 meters diameter booster. While the long march series of active little partner partner core diameter of the largest only 3.35 meters. Long March 5 or a Hercules. It takes about 870 tons of takeoff, about 1060 tons of takeoff thrust, 25 tons of near-Earth orbit carrying capacity, 14 tons of geostationary orbital carrying capacity, and 8 tons of land transfer capacity. Than the previous carrying capacity of the Long March III B rocket carrying capacity increased by more than 2.5 times. This completes the quality of China's rocket carrying capacity of the leap, a substantial increase in our ability to enter the space, the Chinese rockets into the United States and Russia, including the world's mainstream rocket camp. So long five also known as China's first large rocket.
