535 height
Duan Zhiyang said: "No problem, flying a fighter jet is much more exciting than this." Pen? Interesting? Pavilion wWw. biquge。 info”
He is a pilot, and he is a fighter pilot, the physical fitness of this group of people is superhuman, etc., and the minimum can withstand 8g overload, that is, 8 times the standard gravitational acceleration, and the direction of overload is often up or down, without super physical fitness, it is absolutely impossible to withstand such a high overload.
However, unlike fighter planes, rockets only produce backward overloads due to acceleration, while the seats in the spacecraft are specially made to offset the negative effects of overloads to a certain extent.
Such an overload is indeed much more comfortable than flying a fighter.
Huo Qiang didn't want the astronauts to be too nervous, and kept looking for topics to chat with everyone.
The real-time altitude of the aircraft is always displayed in the corner of the main screen, and after about ten minutes, Feitian-1 rises to an altitude of 20 kilometers, and the speed of the climb has decreased significantly, showing signs of follow-up weakness.
The last two engines started in time to continue to propel the aircraft to climb.
After another moment, Feitian-1 jumped to an altitude of 32 kilometers.
Looking at the Earth at this height is very similar to looking at the Earth in the universe, and the sky above you is no longer blue, but as if you have entered an orbit in outer space.
Feitian-1 flew due east at a high speed of Mach 5, which is already the maximum speed of Feitian-1 under load. The intense friction gave the plane a faint red color, and due to thermal expansion and contraction, the length of the plane increased a lot, and some inconspicuous folds in the skin were flattened by the increased length, and the otherwise not very smooth surface became unusually smooth.
These inconspicuous but very important technologies basically come from the Yankees -- if they are researched domestically, they can be done in a period of time, but it is difficult 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 sound of the order, the tail of the rocket carried by the plane splashed with flames, and the same flame flow erupted rapidly, giving the plane new power, and the speed of the plane rose again.
The pilot yelled, "Unlock!" ”
The locking mechanism between the plane and the rocket was immediately untied, the arrow plane separated, and the rocket threw away the heavy burden of the plane, and the speed soared again, rushing into the sky like a sharp sword piercing the sky.
It can be seen very clearly on the screen of the command center that the astronauts are pressed on their chairs by the sudden acceleration, and although the mask obscures their expressions, the atmosphere in the command center is still immediately much tense.
In order to carry the rocket, the shape of Feitian-1 itself 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 a certain distance, and the speed after separation has been reduced to subsonic speed because the shape of Feitian-1 is only suitable for hypersonic flight when carrying a rocket on its back.
However, the super power makes the Feitian-1 extremely maneuverable, and the aircraft's flight attitude 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 rose into the air at an extremely high speed, and after a while, the fuel of the second stage rocket ran out, and after the rocket body separated, the first stage rocket ignited, and after the second stage fell for a moment, a parachute suddenly opened at one end of the cylindrical rocket body.
Due to the shortage of materials, even the space department, which has always been lavish, must make careful calculations, and sending rockets to high altitudes for launch by airplanes is one of the important measures to save space costs.
Another important initiative is the recycling of arrow bodies, which was unimaginable before the insect plague, but is now commonplace.
The recycling of old rockets was not just beginning, but was implemented as early as soon after the discovery of the asteroid swarm, and if the governments of the time had not done so, it would have been impossible to maintain such a high launch frequency during that time.
Rockets have always been a one-time consumable, and governments at that time lacked experience in this area, and there were many accidents and accidents. Today's rockets are redesigned, and the materials used are 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, and eventually it will inevitably lead to accidents, but again, for the country, the life and death of individuals are not worth paying attention to at all.
More than a minute after the separation of the rocket and the rocket, the first stage of the rocket successfully launched the spacecraft into outer orbit, and after separating from the spacecraft, the rocket slowly fell into the atmosphere with the help of the force of separation and separation, and will crash into the Pacific Ocean shortly after.
The spacecraft itself is driven by an electromagnetic engine to a higher orbit, and the astronauts in the spacecraft do not need to stay in their chairs, they leave their seats one after another, hugging and cheering in the cramped spacecraft and even flying around, venting their joy in various ways.
At this point, the launch mission of Kongtian-1 was a complete success, the command center was applauded, and everyone's hearts hanging in mid-air fell together.
Huo Qiang shouted excitedly: "Congratulations! ”
"Serve the people!" I don't know who replied particularly loudly.
In the corner of the command center, Bai Xiaoting burst into tears, silently wishing her husband who was far away in space.
There is no general dividing line between the atmosphere and low-altitude orbits, but the atmosphere becomes thinner with increasing altitude, generally speaking, 100 kilometers above sea level is the dividing line between space and aviation, and the density of air at this altitude is one millionth of sea level.
But thin air doesn't mean it's negligible, if you put a satellite or spacecraft at this altitude, it won't be long before the weak air resistance slows down the speed of the aircraft, and then the spacecraft will crash into the atmosphere.
As a result, the lowest orbits of spacecraft are all above 120 kilometers above sea level, and the density of air at this altitude is only 1/10 millionth of the sea level.
Of course, higher altitudes are also not immune to weak atmospheric resistance, for example, the orbital altitude of the International Space Station decreases by about four kilometers per month, so every once in a while, the orbit has to be changed to increase the altitude.
Tiangong's orbit is close to 400 kilometers above sea level, where two astronauts are currently stationed. A few hours later, the altitude of the orbit of Kongtian-1 was level with that of the space station, and after the spacecraft stabilized the orbit, it slowly approached Tiangong.
Duan Zhiyang, a pilot, is responsible for maneuvering the spacecraft to dock with the space station.
Although countless simulation training has been carried out on the ground, it is the first time to actually control the spacecraft to dock, but fortunately, Duan Zhiyang's psychological quality is good, and the two crosses on the screen always keep overlapping.
As the spacecraft got closer, the screen suddenly shuddered, and the airlock cladding overlapped, and the locking device immediately locked, tightly connecting the spacecraft and the space station.
