The power of the Long March 6 is pollution-free. It is a newly developed non-toxic and pollution-free high-pressure afterburner liquid oxygen kerosene engine in China. This kind of engine uses liquid oxygen as oxidant and kerosene as fuel. This can reduce fuel carrying, and kerosene will produce carbon dioxide and water after burning, which will not cause pollution. Moreover, the Long March 6 has a unique engine oxygen tank, which can generate its own pressurization technology, which is also the biggest highlight of this rocket. The bottom cabin of Long March 6 mezzanine is made of heat insulation composite material, which can resist the temperature difference of 200℃. This technology was developed by scientists through layer-by-layer experiments. Through repeated experiments and improvements, we finally mastered a series of manufacturing technologies such as laser scanning and replication processing, so that the Long March 6 can resist the temperature difference of 200℃. The flight process of Long March 6 looks simple, but only through rapid ignition separation and many complicated actions can the accurate launch be guaranteed. Not only the control system is extremely high, but also the sky survey technology is equipped with very professional clairvoyance technology, which can realize point-to-point launch. You need to know how sophisticated technology is needed to launch a rocket into space accurately. After continuous improvement and repair by scientists and designers, the Long March 6 was finally launched successfully. This moment is very complete and worthy of the pride of the Chinese people.
