The maximum China rocket fat five 20 storey jeuro Sohu made its inaugural flight completely bypassin

The maximum Chinese rocket " five " fat; 20 storeys high, completely bypassing Japan and Europe made its inaugural flight – Sohu military channel map information: deciphering the country’s first high thrust rocket " " five; fat; highlights.   central broadcasting network Hainan on November 3rd news: China’s current development level, the largest diameter of the largest carrying capacity in March five rocket in China Wenchang spaceport successful first flight, the future will have China manned space station, three lunar exploration and exploration of Mars and other major launch task. What are the characteristics of the long march five launch vehicle? What new technologies are used? The largest diameter, high and mighty, the long march rocket number five because of its special shape and has a special title — "fat five". "Fat five large core diameter of 5 meters, and the current active rocket the maximum diameter of only 3.35 meters. A total length of about 57 meters, equivalent to the height of 20 storeys. It’s strength is also large, with the international mainstream of large launch vehicles, with 25 tons of near earth orbit, geostationary transfer orbit carrying capacity of 14 tons. Long march five first flight mission launch Field Command commander Wang Jue: "Five" means our country put the original four series from long ago, the so-called pre carrying capacity increased by 2.5 times, increase nearly 1 times longer than 7 words, the ability to jump in our national progress space. From the carrying capacity of its performance is fully beyond Europe and Japan, is now the European Ariane 5 rocket and Japan’s H2-B large rocket to be advanced." As China’s most capable of carrying a rocket, long march five takeoff thrust reached a total of 1060 tons. The main thrust is provided by the 4 booster on the installation of 8 sets of 120 tons of liquid oxygen kerosene engine. Long march five on a "big heart", is China’s largest "thrust LOX / kerosene engine". 120 tons of liquid oxygen kerosene engine how much power? Some people have made an analogy, it can be the pressure of the Huangpu River, Shanghai water hit 5000 meters high in the Qinghai Tibet plateau. Wang Jue: it refers to the ability that the turbine pump booster pump, booster pump capacity from several pressure will be increased to nearly 500, 500 after the pressure is equivalent to let the sea water pressure, water level can rise to more than 5000 meters, so the equivalent of the Qinghai Tibet Plateau height. It mainly refers to the ability to boost, because it needs to maintain such a high pressure combustion environment. From the overall power of the long march five look, four booster using LOX / kerosene engine, the core is liquid rocket engine collocation. Why is this set? The chief designer of the long march rocket number five li Dong travel with food made by analogy, explained the two kinds of engine collocation rationality, also is the use of liquid hydrogen and oxygen characteristics of high specific impulse, small density, light weight, and the use of liquid oxygen kerosene thrust, quality characteristics. Li Dong: for example, tomorrow I go to climb the mountain, you have to take your food, with two kinds of food, a tin, a large bread, you choose to eat, eat iron can give priority to heavy things, eat, can.相关的主题文章:
