Duan Zhiyang said: "No problem, flying a fighter jet is much more exciting than this."
He is a pilot and a fighter pilot. The physical fitness of this group of people is superhuman. They can withstand at least 8g overload, which is 8 times the standard gravity acceleration, and the overload direction is often upward or downward. They do not have super physical fitness.
It absolutely cannot withstand such a high overload.
However, rockets are different from fighter jets in that acceleration only produces backward overload, and the seats in the spacecraft are specially designed to offset the negative effects of overload to a certain extent.
This kind of overload is indeed much more comfortable than flying a fighter jet.
Huo Qiang did not want the astronauts to be too nervous and keep looking for topics to chat with everyone.
The real-time altitude of the aircraft was always displayed in the corner of the main screen. About ten minutes later, Feitian-1 rose to an altitude of 20 kilometers. The climbing speed dropped significantly, and there were signs of subsequent fatigue.
The last two engines started in time and continued to push the aircraft to 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 a pitch black sky as if it has entered outer space.
Feitian 1 flies due east at a high speed of Mach 5, which is already the highest speed of Feitian 1 when it is loaded. The violent friction makes the aircraft appear faint red. Due to thermal expansion and contraction, the length of the aircraft has increased a lot.
Some inconspicuous wrinkles on the skin have been smoothed out by the increased length, and the originally not-so-smooth surface has become extremely smooth.
These inconspicuous but very important technologies basically come from the Americans - if they are researched domestically, it will take a while, but it is hard to say when the results will be produced.
The pilot promptly reported: "Command center, Feitian 1 has arrived at the predetermined altitude!"
"ignition!"
At the command, the tail of the rocket carried by the aircraft splashed with flames, and the flames spurted out, giving the aircraft new power, and the speed of the aircraft increased again.
The pilot yelled: "Unlock!"
The locking mechanism between the aircraft and the rocket was immediately released, the arrow and aircraft separated. The rocket threw away the heavy burden of the aircraft, and its speed soared again, rushing into the sky like a sharp sword piercing the sky.
It could be clearly seen on the screen in the command center that the astronauts were pressed into their chairs by the sudden acceleration. Although their expressions were blocked by masks, the atmosphere in the command center was still immediately tense.
In order to carry the rocket on its back, the shape of Feitian-1 is not particularly smooth. Although the air at high altitude is thin,
After separating from the rocket, the aircraft body stabilized its attitude after descending for 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.
But the super power gives Feitian-1 extremely strong maneuverability, and the aircraft's flying attitude is extremely light.
But at this time, no one cared about the situation of Feitian No. 1. Everyone's attention was focused on the spacecraft.
The rocket took off at a very high speed. After a while, the second-stage rocket ran out of fuel. After the rocket body separated, the first-stage rocket ignited. After the second-stage rocket body fell for a moment, one end of the cylindrical rocket body suddenly opened.
A parachute.
Due to the shortage of supplies, even the aerospace department, which has always been extravagant, must live on a prudent basis. Using aircraft to launch rockets into high altitudes is one of the important measures to save aerospace costs.
Another important measure is the recycling of rocket bodies. This was unimaginable before the insect disaster, but now it is commonplace.
The recycling of old rockets did not just start, but was implemented soon after the discovery of the asteroid group. If the governments of various countries at that time had not done so, it would have been impossible to maintain such a high launch frequency during that period.
Rockets have always been disposable consumables. At that time, governments lacked experience in this area, and many accidents and accidents occurred. Today's rockets have been redesigned, and the materials used are also the most cutting-edge achievements of various countries, which makes the quality of rockets
It has been greatly improved, making multiple recycling possible.
Repeated recycling will definitely cause quality problems and eventually lead to accidents, but again, as far as the country is concerned, personal life and death is not worthy of concern at all.
More than a minute after the rocket separated, the first-stage rocket successfully sent the spacecraft into outer space orbit. After separating from the spacecraft, the rocket slowly fell into the atmosphere with the help of the force of separation, and will fall into the Pacific Ocean soon.
The spacecraft itself changes its orbit to a higher orbit driven by the electromagnetic engine. The astronauts in the spacecraft do not need to stay in their chairs. They leave their seats one after another, hug and cheer in the narrow spacecraft and even fly around, using various methods.
Vent the joy in your heart.
At this point, the launch mission of Kongtian-1 was a complete success, the command center burst into applause, and everyone's hearts dropped in mid-air.
Huo Qiang shouted excitedly: "Congratulations!"
"Serve the people!" I don't know who replied loudly.
In a corner of the command center, Bai Xiaoting burst into tears, silently blessing her husband in space.
There is no general dividing line between the atmosphere and low-altitude orbit. Instead, the atmosphere becomes thinner as the altitude increases. Generally speaking, an altitude of 100 kilometers is the dividing line between aerospace and aviation. The density of the air at this altitude is that of sea level.
One millionth of .
But the thinness of the air does not mean that it can be ignored. If a satellite or spacecraft is placed at this height, it will not take long for the weak air resistance to slow down 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 altitude is only one ten millionth of that at sea level.
Of course, higher altitudes cannot avoid weak atmospheric resistance. For example, the orbital altitude of the International Space Station decreases by about four kilometers every month, so it must change its orbit to increase its altitude every once in a while.
Tiangong's orbit is close to an altitude of 400 kilometers, and two astronauts are currently stationed there. A few hours later, the orbit height of Kongtian-1 was equal to that of the space station. After the spacecraft stabilized its orbit, it slowly moved closer to Tiangong.
Duan Zhiyang, a former pilot, is responsible for controlling the docking of the spacecraft with the space station.
Although he had conducted countless simulation trainings on the ground, this was the first time he actually controlled the docking of a spacecraft. Fortunately, Duan Zhiyang's mental quality was good and he always kept the two crosses on the screen coincident.
As the spacecraft got closer and closer, the screen suddenly trembled, the airlock cladding overlapped, and the locking device immediately locked, tightly connecting the spacecraft and the space station.
