Why is the rocket engine still burning out of space even without oxygen?

The question extends from the childhood of many people to missile spacecraft here.

Probably once a child, most of the dreamy souls in us had once dreamed of a certain occasion to fly away from Earth, to explore the universe with spacecraft and extreme missiles " cool " . Of course, growing up, we know that to do that is not easy at all in terms of means, technology and skills.

However, there is certainly a question that so far, each person's brain may not yet understand why it happened. It was even though there was no oxygen outside the universe, but the rocket could still burn the engine and fly billions of kilometers out there. Why is this "miracle" ?

The rocket is an unexploded jet engine and has the most powerful thrust of current technology.

First of all, we need to understand the definition of missiles. This is a no-hole jet engine and has the most powerful thrust of current technology. Its power must be enough to overcome its equally massive gravity. According to the same estimate, its impact would be equal to 10,000 cars on the road pulling at the same time.

The spacecraft bringing people into space will not be able to fly without a rocket engine. Therefore, rockets are one of the core elements to realize human mission. It will help propel the spacecraft by discharging a stream of fire to the ground, creating a counter-direction.

However, its main role is to help the spacecraft fly out into space, not every Earth's atmosphere. Therefore, there will be no natural oxygen in the outer space as we breathe daily to maintain combustion. And the key to this question is elsewhere.

Push and pull

The propulsion helps to send missiles and spacecraft flying straight up based on the amount of gas discharged and the flow of discharge over time to create pressure. Once enough to overcome the gravity and significantly more difference, it will take the spacecraft to implement its plan. It is known that not only the gravity is the "enemy" but also the resistance of the air is also a factor that makes the rocket work more than ever.

Compared to the current commercial aircraft engine, this is a little different: Jet does not go upright, but glides very fast in the horizontal direction because the air resistance to the aircraft has 2 The wing is used to act as a force-driven element, helping to lift the plane higher when surfing. The faster you move, the greater the force of support and support to raise and fly further. And to limit negative air resistance when flying fast, high-speed vehicles are always tapered on their bodies - including missiles - to minimize it.

Jet propulsion system is the most important part , as mentioned. And the reason they can fly high, far and far out of space is billions of kilometers because there is a huge oxygen tank stored in the engine. It will "feed" the constant propellant, not to turn off even when the universe is without oxygen.

There may be 2 separate compartments for 2 separate fuel and gas tanks.

More modern missile generations can also use another support alternative : liquid fuel - such as liquid oxygen or liquid hydrogen - simultaneously spraying to maintain combustion. They were originally stored at extremely low temperatures and compressed at high pressure to be able to carry as much as possible in giant containers, helping the spacecraft fly farther and produce even more productivity.

So, now the question for your childhood dream has been answered completely satisfactory.
