Leisure time is long, and when busy, time is like flowing water all of a sudden, and slipping away without knowing it. 【Literature Building】
In half an hour, more than half a month passed, during which the Qingquan Technology Supplier Conference was held vigorously, and all parties divided up most of the quotas of Qingquan Technology's suppliers. A few lucky small companies also obtained their own solid technical forces The coveted contract.
Liu Qingquan was too busy, and the supplier conference did not go. The big things have already been settled. There is no need for him to show up at all. During this time, he has been immersed in the laboratory.
With a larger and larger team, they are solving the technical problems in the rocket a little bit. Fortunately, they have cultivated the Yuanli method specially developed for scientific researchers, and the research and development capability of Qingquan Technology is extremely strong.
Coupled with Liu Qingquan's willingness to invest, all kinds of materials, equipment, funds, etc. fell down, rich money is easy to do! Many things can be bought for money.
Of course, rockets can't be achieved with money, not to mention designing everything by yourself. Many times, the problems encountered are enough for the entire institute to have headaches. Of course, at this time, Liu Qingquan will go to the seed space for help, countless problems. In this way, they were conquered one by one in concert.
On January 15, 2022, Liuyun Town at this time is the best time of the year. The weather is sunny and the climate is comfortable and pleasant. Today is a good day without wind, and a good day for rocket experiments.
A remote place in Liuyun Town. This place is called Wild Boar Ridge. There is nothing else except the humming wild boar on the mountain. People from Qingquan Technology have already built a rocket launching site here. The country's Jiuquan and Xichang satellite launch centers are simply incomparable. Here, they simply build a wide road to a small high ground.
The top of the mountain was pushed flat early. The original tens of meters of the hill was pushed only 10 meters high. With the flat land filled out, the entire site area was over 10,000 square meters.
There are many other buildings built next to the site. On the mountain not far away, some newly-built quantum communication radio stations, 3D stereo radar stations, radio astronomical telescopes, etc. stand quietly.
In the middle of the huge high-standard cement site is a launch pad. Outside the site are some two-story command centers filled with various equipment, and even the black technology manufactured by Liu Qingquan based on Alpha technology. device.
"For a few suppers, Zhou Jingbo is also good enough! Stay up all night and work overtime every day. I didn't expect to have a perfect product in half a month." Liu Qingquan smiled and looked at the quantum communication equipment in his hand and the appearance of ordinary equipment. It makes no difference, but the technology involved is a few generations apart.
"Each group reports its preparations," said Liu Qingquan, picking up the intercom.
"The rocket erection team is ready!"
"The radar is ready!"
"Communication is OK!"
"There is no one in the middle of the field, normal!"
...
"Preparation for the Ninth Rocket Experiment" Liu Qingquan looked at the rocket in the middle of the field. Well, this is not a rocket yet, because this rocket is far too different from the rocket that everyone remembers.
Compared with the traditional rocket, which is more than 40 meters in height and 3-5 meters in diameter, the rocket designed by Qingquan Technology and others is really a small dwarf melon, but it is only 4 meters high, 2 meters in diameter at the bottom, and then it gets fatter. The middle position has a diameter of more than 3 meters, and then gradually thins, and bears a conical head.
Of course, this rocket is just an experimental product, because the shape is too much like a fat man with a big belly. It was named "Fatman 9" by a group of imaginative people like Qingquan Technology.
The "Fat" series of rockets was researched by Qingquan Technology and others, and was prepared to launch satellites in the later stage. So far, it has been tested 8 times before and after. This is the 9th experiment.
The fairing of the "Fat" rocket is a new material developed and designed by Qingquan Technology's new material company, a semi-hard shell aluminum alloy material. The overall light weight, heat insulation and high temperature resistance, and the penetration of communication signals are very good, which can ensure the ground. And the rocket.
The "fat" shell material is also a specially developed alloy material, which is lightweight, high hardness, adiabatic and high temperature resistant, and has poor cold shrinkage performance. It will not cause too much thermal expansion and cold shrinkage due to drastic changes in temperature.
As a test product, there is naturally no satellite or something in the "fat". The instrument cabin on the top only contains some key equipment, communication equipment, electronic control equipment, gyroscope, detector ... and so on.
The following power system uses a dual-engine design, an anti-gravity engine and a jet engine. The fuel is liquefied hydrogen and oxygen. The fuel density is suitable, the heating value is high, the combustion performance is good, and it can be fast, stable, continuous, It is completely burned, and the burning area is small. The burning waste is water and will not coke.
Of course, although the hydrogen-oxygen combustion can generate a huge calorific value, it requires very high purity of hydrogen and oxygen, almost 100%. The previous experiments of Qingquan Technology were because the purity was not sufficient, which caused unstable combustion and a huge explosion. .
Fortunately, the fat of Qingquan Technology is an experimental product, and because it has an anti-gravity engine design and a first-level overall design, the fuel in it is not much, and Qingquan Technology has also made comprehensive preparations, which did not cause What a big loss was just a large firework.
Speaking of the previous 8 experiments, three times were because the fuel purity was not enough, the combustion was unstable, and explosions did not occur much when lifted off. Two times they flew into the sky and exploded due to the problem of the internal support. Five consecutive fireworks were fired. In the next three times, the fireworks were finally released, and they could be lifted off smoothly and reached the designed speed and height, but the fall speed was not controlled during the return and recovery process, and the entire "fat" fell to pieces.
"Everyone, countdown to launch! 10! 9! ... 3! 2! 1! Launch!" With Liu Qingquan launching two words and saying, the staff who had been prepared a long time, gently pressed the red launch button .
On the launch pad in the middle of the field, a circle of heat wave erupted instantly, and a red flame emerged from the bottom of the "fat", and then the "fat" slowly started to lift off.
As the flame slowly changed from orange-red to talk-red and then to scorching white, the fat rocket was getting faster and faster, and the fairing on the top was like a Buddha bullet, which opened the thick air and formed a beautiful cyclone.
The bottom of the rocket has a long white tail flame that is more than ten meters long and generates high temperatures of more than 4000 degrees Celsius. Because the tail of the rocket is close to the root of the flame, it must be lowered. The metal-ceramic composite material is used. A cermet made by mixing it evenly with metal powder and then sintering at high temperature. It is hard and tough, and has a low density and high temperature resistance.
Looking at the rocket that has gradually disappeared from the field of vision, Liu Qingquan turned to look at the huge display next to it. The rocket's various data columns are very detailed and updated at any time.
At an altitude of 20,000 meters and a speed of Mach 30, that is 102 km / s, exceeding the first cosmic speed 79 km / s, and the speed is still accelerating. The internal temperature of the rocket is normal, the shell temperature is 2000 degrees Celsius, and the remaining fuel is 80%. Constantly changing, the comprehensive status display is always green, indicating that the data is perfect.
"The communication group reports the communication situation," said Liu Qingquan, picking up the intercom.
"The quality of the electromagnetic wave communication is poor, and the quantum communication is normal."
"The radar team reports" Liu Qingquan continued to ask.
"The situation is normal and can be tracked normally"
...
Soon, the fat rocket flew out of the stratosphere and reached the upper atmosphere. At this time, as long as it continued to fly into outer space, it would soon reach the altitude of low-level satellite launch.
However, today Fatty 9 is a test product, and it is not ready to really fly into outer space. At this altitude, the test is basically successful, if it is only used as a disposable rocket.
What Qingquan Technology wants is a recyclable rocket. Naturally, there are more difficult considerations. The launch can only be considered half successful, and the remaining half. The intact recovery of the rocket is the real problem.
"The rocket returns, please pay attention to each group." Liu Qingquan ordered the rocket to return after watching the rocket reach the predetermined height.
When launching, it is necessary to get rid of gravity and consume very much fuel. This return flight can completely turn off the counter-motor and use gravity to attract the rocket.
I saw that the fat man's head was facing down, and the Buddha was shooting down like a meteor, bringing a long flare, which is actually very dangerous at this time, because if the control is not accurate, a comet will be installed on the earth, which will cause Huge destruction, that loss can not be imagined.
Fortunately, the fat was controlled very accurately. When descending to a height of 10,000 meters, the two engines were re-ignited and started. With the work of the anti-gravity engine, the fat's falling speed was significantly reduced instantly, and then fell quickly. Speed ​​slowed down.
At the same time, with the adjustment of the tail engine of the jet engine, the entire fat man slowly changed from head down to horizontal, and then after flying a distance across the head, the head turned up, just as it was when it was launched.
This step can be said to be the most critical step for recyclable rockets. The key to success and failure is to see if the rocket can change direction and turn the tail down. Because only the tail is down, the jet engine can slowly reduce the falling speed. Eventually, Achieving safe recovery.
"Fatman No. 9" head up, under the combination of anti-gravity engine and jet engine, the height slowly decreased, while at the same time according to the position of the fat, through the tail to continuously adjust the landing direction.
Soon, the fat man reappeared in everyone's field of vision. Over the field, Fat Man 9 slowly aimed at the launch pad and landed slowly. The flame at the tail gradually changed from white to orange, and then the fat man slowly landed. On the launch pad, the engines all stopped.
"Yeah ~~~ We succeeded" Instantly, the console and the tracking platform, everyone cheered, even Liu Qingquan was excited like a child dancing! Mobile users, please visit m.wenxue6.com to read, a better reading experience.
