Five Hundred Thirty Five Height

Duan Zhiyang said: "No problem, flying a fighter jet is much more exciting than this."

He is a pilot, and he is a fighter pilot. The physical fitness of this group of people is superhuman, and they can withstand a minimum of 8g overload, which is 8 times the standard acceleration of gravity, and the direction of overload is often upwards or downwards. They do not have super physical fitness. Absolutely can not bear such a high overload.

But rockets are different from fighter planes, acceleration only produces backward overload, and the seats in the spacecraft are all specially made, which can offset the negative effects of overload to a certain extent.

Such an overload is indeed much more comfortable than flying a fighter jet.

Huo Qiang didn't want the astronauts to be too nervous, and kept looking for topics to chat with everyone.

A corner of the main screen always displays the real-time altitude of the plane. About ten minutes later, Feitian-1 ascended to an altitude of 20 kilometers, and the climbing speed dropped significantly, showing signs of subsequent fatigue.

The last two engines started in time to continue propelling the aircraft up the climb.

After a while, Feitian-1 jumped to an altitude of 32 kilometers.

Looking at the earth at this height is very similar to observing the earth in the universe. There is no longer a blue sky above the head, but it is as dark as entering outer orbit.

Feitian-1 is flying due east at a high speed of Mach 5, which is already the highest speed of Feitian-1 under load. The intense friction made the plane appear reddish. Due to thermal expansion and contraction, the length of the plane increased a lot. Some inconspicuous folds on the skin were flattened by the increased length, and the originally not very smooth surface became extremely smooth.

These inconspicuous but very important technologies basically come from the Yankees - if it is researched domestically, it will take a while to get it done, but it is hard to say when the results will be produced.

The pilot reported in time: "Command center, Feitian-1 has reached the predetermined altitude!"

"ignition!"

With an order, the tail of the rocket on the plane's back was splattered with flames, and the same stream of flames spewed out, giving the plane new power, and the speed of the plane climbed again.

The pilot shouted: "Unlock!"

The locking mechanism between the plane and the rocket was released immediately, and the rocket plane separated. The rocket cast aside the heavy burden of the plane, and the speed soared again, rushing towards the sky like a sharp sword piercing the sky.

It can be seen very clearly on the screen in the command center,

The astronauts were all pressed down on their chairs by the sudden acceleration. Although the masks blocked their expressions, the atmosphere in the command center was still tense immediately.

In order to carry the rocket on its back, the shape of Feitian-1 itself is not particularly smooth. Although the air in the sky is thin,

After separating from the rocket, the aircraft body stabilized its attitude after descending a certain distance. Since the shape of Feitian-1 is only suitable for supersonic flight when carrying a rocket on its back, the speed after separation has dropped to subsonic speed.

However, the super power makes Feitian-1 have extremely strong maneuverability, and the flying attitude of the aircraft is extremely light.

But at this time, no one cared about the situation of Feitian-1 at all, and everyone's attention was focused on the spaceship.

The rocket lifted off at a very high speed. After a while, the fuel of the second-stage rocket was exhausted. After the rocket body was separated, the first-stage rocket ignited. After the second-stage rocket body fell for a while, one end of the cylindrical rocket body suddenly pulled apart. A parachute.

Due to the shortage of materials, even the aerospace sector, which has always been extravagant, must live on a budget. Using an airplane to send rockets to high altitudes for launch is one of the important measures to save aerospace costs.

Another important initiative is the recycling of rocket bodies, which was unimaginable before the plague, but is now very common.

The recycling of old rockets was not just started, but started shortly after the discovery of the asteroid group. If the governments at that time had not done so, it would have been impossible to maintain such a high launch frequency during that time.

Rockets have always been disposable consumables. The governments of various countries at that time lacked experience in this area, and there were many accidents and accidents. Today's rockets are all redesigned, and the materials used are also the most cutting-edge achievements of various countries, which greatly improves the quality of the rockets and makes it possible to recycle them many times.

Repeated recycling will definitely lead to quality problems, which will inevitably lead to accidents in the end, but still the same sentence, for the country, personal life and death are not worthy of attention at all.

More than a minute after the aircraft and rocket separated, the first-stage rocket successfully sent the spacecraft into outer orbit. After separating from the spacecraft, the rocket slowly fell into the atmosphere with the help of the separation force, and will soon fall into the Pacific Ocean.

The spacecraft itself is driven by the electromagnetic engine to change its orbit to a higher orbit. The astronauts in the spacecraft do not need to stay in the chairs. They leave their seats one after another, hug and cheer in the narrow spaceship and even fly around. Vent the joy in my heart.

So far, the launch mission of Kongtian-1 was a complete success, the command center applauded, and everyone's hearts hanging in the air fell together.

Huo Qiang shouted excitedly: "Congratulations!"

"Serve the people!" Someone replied loudly.

In the corner of the command center, Bai Xiaoting burst into tears, silently blessing her husband who is far away in space.

There is no dividing line between the atmosphere and low-altitude orbit in the general sense, but the atmosphere becomes thinner as the altitude increases. Generally speaking, an altitude of 100 kilometers is the dividing line between aerospace and aviation. The air density at this altitude is that of sea level one millionth of.

But thin air does not mean it can be ignored. If a satellite or spacecraft is placed at this altitude, it will not take long for the weak air resistance to slow down the speed of the aircraft, and then the high-altitude spacecraft will fall into the atmosphere.

Therefore, the lowest orbit of the spacecraft is above 120 kilometers above sea level, and the air density at this height is only one ten-millionth of sea level.

Of course, a higher altitude cannot avoid weak atmospheric resistance. For example, the orbital altitude of the International Space Station decreases by about four kilometers every month, so every time, it is necessary to change the orbit to increase the altitude.

The orbit of Tiangong is close to 400 kilometers above sea level, and there are currently two astronauts stationed there. A few hours later, the orbital height of Kongtian-1 was level with the space station, and after the spacecraft stabilized its orbit, it slowly approached Tiangong.

Duan Zhiyang, who was born as a pilot, was in charge of manipulating the spacecraft to dock with the space station.

Although countless simulation trainings have been carried out on the ground, it is the first time to actually control the docking of the spacecraft. Fortunately, Duan Zhiyang has a good mental quality, and he always keeps the two crosses on the screen coincident.

As the spacecraft got closer and closer, the screen suddenly trembled, the cladding of the airlock overlapped, and the locking device locked immediately, tightly connecting the spacecraft and the space station.
