The rocket needs fuel to power its launch. How much fuel does the rocket need to take off?

Space science and technology such as rockets, spaceships and space stations have always been the embodiment of the concentrated wisdom of all countries, reflecting the infinite reverie and yearning of mankind for the vast universe. Behind the successful launch of the rocket, it is inseparable from the hard-working scientific and technological personnel and front-line workers behind us. For example, the successful launch of the Long March 3 series requires hundreds of tons of hydrogen, oxygen and kerosene fuel.

First, let's look at the principle of rocket launch. The fuels of spacecraft in China, such as Long March series launch vehicles, are liquid hydrogen and liquid oxygen. The biggest advantage is that the gas is easy to compress and the production cost is low. Some launch vehicles use solid rocket materials, and the whole rocket is mostly solid fuel, which accounts for most of the whole rocket and has high kinetic energy. The launch of the rocket is equivalent to controlling every small explosion. These difficulties can be imagined. The successful launch of a rocket requires the cooperation and interaction of all parts.

The speed at which each rocket consumes rocket fuel is amazing. It takes about 10 minutes from launch to successful launch, which will consume 100 tons of rocket fuel. Nowadays, there are great innovations in launch conditions and fuel. Hydrogen-oxygen rockets used in China Long March series carrier rockets are almost harmless to the environment after burning, because the substance produced by burning these fuels is water. The powerful engine retreated the spacecraft from the earth and rushed to the universe at the first cosmic speed on earth, drawing a white belt on the blue sky.

The fuel of a rocket is configured by researchers in different content ratios under specific tasks and specific launch environments, so the fuel is different every launch. It is necessary to accurately calculate the launch orbit and fuel to ensure the return flight and normal work needs of spacecraft and astronauts. Every rocket launch is the result of careful study by researchers.

Therefore, every time a rocket is launched, it consumes hundreds of tons of fuel. Thank the motherland for its strength and pay tribute to all the researchers who study two bombs and one satellite.
