Great Power Technology: Domination Of The World Starts With Chips

"Amazing!"

Yang Wei praised sincerely.

In the technology of aerospace engines, it is definitely a very difficult step to realize the transition from aviation mode to aerospace mode.

And it is even more difficult to complete the switch in a short enough time.

Because, if the switching time is too short, the plane whose rising speed is more than 250 meters per second will start to drop rapidly due to the gravity of the earth again.

However, at a height of tens of kilometers, the gravity received still does not change much, at most it can be reduced by one or two percentage points. In this way, the acceleration of gravity is calculated as 9.6. Because of the thin air, the air resistance can also be temporarily ignored. If so, the plane will change from ascending to descending in just half a minute.

If the fire is re-ignited at that time, there will be a lot of pressure on the entire body, and it may also be due to uneven force, and the air in the middle layer is unevenly cold and hot, and there is a violent vertical movement of the air, which will cause the body to lose weight. The layer started to wobble and eventually got out of control.

This is related to the gravitational potential energy and its own kinetic energy. Therefore, the most ideal situation for an aerospace engine is that the switch from aviation mode to aerospace mode will not consume time, or seamlessly, which is the most stable.

Of course, seamless connection is an ideal state, but it is obviously not possible to achieve this level in actual situations.

However, as long as it can ensure that the airframe is still in the rising state to complete the ignition in spaceflight mode, it will be successful.

But obviously, this is not something that can be done by saying and doing.

Soon, after a brief celebration, the people present refocused their attention on the Dragon God, which was getting closer and closer to the earth's orbit.

Under the huge thrust of the space mode, the speed of Dragon God began to climb again.

However, although the thrust is large, the acceleration is actually not high. This is because the Dragon God does not need to fly vertically. You must know that the earth is round, so even if the plane is flying flat, it can always fly out of the atmosphere.

Just like a rocket, it does not enter the orbit vertically, but after reaching an altitude of tens of kilometers, it starts to use gravity as acceleration, which can also save fuel.

Therefore, the maximum acceleration of the Dragon God does not exceed 3 G, and in this way, the acceleration is smooth and steady, and the height is raised quietly.

Time is also gradually passing.

"The speed of the Dragon God is increasing, and it has now increased to 1,000 meters per second."

"2000 meters per second."

"3000 meters per second."

"..."

Generally speaking, a satellite needs to reach the first cosmic speed in order to realize orbiting the earth.

As for the speed of the first universe, for example, a car running at a speed of 120 kilometers per hour at a high speed is only 33 meters per second, and then maintains this speed to run for an hour, and the rocket only needs to run for a few tens of seconds.

And the current Dragon God is rushing towards this speed.

At the same time, as the speed continued to rise, the height of the Dragon God had already climbed to the level of the outer layer of the atmosphere.

"Currently, the Dragon God has reached an altitude of 200 kilometers and is ready to enter the scheduled orbit."

Ordinary spacecraft fly at a position of about 300 kilometers above the ground, the International Space Station is at an altitude of 320 kilometers, and the Tiangong Space Station is at an orbital height of nearly 400 kilometers.

As for the Dragon God, at its current height, it already feels a little light. The outer layer of the atmosphere has almost no air, and it is finally possible to see the dark universe.

At the same time, after the Longshen broke through this altitude, four Hall thrusters with a total thrust of 100N were also successfully activated.

The Hall thruster does not have the spectacular tail flame of the chemical thruster, but the blue light that emerges still has a sense of science fiction. Of course, people on the earth can't see this thing. 7K 妏敩

In this way, the altitude of the Dragon God became higher and higher, and finally successfully reached an altitude of 400 kilometers, and successfully entered the predetermined orbit, and began to revolve around the earth.

"it is good!"

There was another burst of cheers from the ground command center.

At this point, it basically means that it has been successful.

Next, it is to perform various tasks.

The Ryujin will not perform its return mission until a few days later.

However, the current achievement, sending an aircraft into satellite orbit, is enough to make the space powers all over the world feel ashamed.

And this also shows that Zhiqi Company will become the world's number one private aerospace company, and SpaceX's status will plummet.

In fact it is.

Zhiqi Company did not conceal the news of the launch of the Dragon God, and even directly broadcasted it live. The live broadcast room has already gathered tens of millions of viewers from all over the world.

For people on earth, I believe that everyone envies those astronauts who can enter the universe, and this time Zhiqi Company showed the first flight of an aerospace plane, a spacecraft that everyone can sit on, who would not want What about experiencing it?
