Dahan Technology Empire

Leisure time is long, and when you are busy, time is like flowing water, and it slips away without you noticing.

More than half a month has passed in a blink of an eye. During this period, the Qingquan Technology Supplier Conference was held vigorously. All parties divided up most of the supplier quota of Qingquan Technology, and a few lucky small enterprises also won the prize with their solid technical power. A dream contract.

Liu Qingquan was too busy, and he didn't attend the supplier conference. The big things had already been decided, and there was no need for him to come forward. During this time, he had been immersed in the laboratory.

With an increasingly large team, they are overcoming the technical problems in rockets little by little. Fortunately, they have practiced the Yuanli method specially developed for scientific researchers. Qingquan Technology's research and development capabilities are extremely powerful.

Coupled with Liu Qingquan's willingness to invest, all kinds of materials, equipment, funds, etc. are thrown down, money is easy to do! Many things can be bought with money.

Of course, making a rocket is not something you can do with money, not to mention you have to design everything yourself. Many times, the problems encountered are enough to cause headaches for the entire research institute. Of course, at this time, Liu Qingquan will go to the seed space to find help. There are countless problems. In this way, they were conquered one by one with the concerted efforts of everyone.

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 it is also a good day for rocket experiments.

A remote place in Liuyun Town, this place is called Wild Boar Ridge. There is nothing else but the humming wild boars on the mountain. The early Qingquan Technology people have built a rocket launch site here. Of course, compared to The country's Jiuquan, Xichang, and satellite launch centers can't be compared at all. Here, a wide road is simply built to a small high ground.

The top of the mountain was flattened early, and the hills that were tens of meters high were pushed down to just over 10 meters high. In addition to the flat land that was filled in, the entire site covers an area of ​​more than 10,000 square meters.

There are also many other buildings built next to the site. On the mountain not far away, some new quantum communication stations, 3D stereo radar stations, and radio astronomical telescopes are quietly standing.

In the middle of the huge high-standard cement field is a launch pad. Outside the field are some two-story command centers, which are filled with various equipment, and even the black technology created by Liu Qingquan based on Alpharen technology. equipment.

For a few supper, Zhou Jingbo and the others have done enough work! Staying up all night and working overtime every day, I didn't expect to come up with a perfect finished product in half a month. Liu Qingquan smiled and looked at the quantum communication device in his hand, and the appearance of the ordinary device There is no difference, but the technology involved is a few times different.

The teams report their preparations, Liu Qingquan said as he picked up the walkie-talkie.

The rocket erection team is ready!

The radar is ready!

Communication is normal!

There is no one in the middle of the venue, it's normal!

...

Preparation for the 9th rocket experiment Liu Qingquan looked at the rocket in the middle of the field, um~ this can't be regarded as a rocket, because this rocket is really different from the rocket in everyone's impression.

Compared with traditional rockets that are more than 40 meters high and have a diameter of 3-5 meters, the rocket designed by Qingquan Technology and others is really a small winter melon, only a little over 4 meters high and 2 meters in diameter at the bottom. The diameter of the middle position reached more than 3 meters, and then slowly became thinner, with a cone-shaped head.

Of course, this rocket is just an experimental product, because it looks too much like a fat man with a big belly. It was named Fat Man No. 9 by imaginative people like Qingquan Technology.

The Fat Man series of rockets were developed by Qingquan Technology and others, and were later used to launch satellites. So far, 8 experiments have been carried out before and after.

This is the ninth experiment.

The fairing of the Fat Man rocket is made of a new material developed and designed by Qingquan Technology's new material company. It is a semi-monocoque aluminum alloy material. connection with the rocket.

The shell material of Fat Man is also a specially developed alloy material, which is lightweight, high in hardness, heat-insulating and high-temperature resistant, and at the same time has poor cold-shrinking performance, and will not experience too much thermal expansion and contraction due to drastic changes in temperature.

As a test product, there are naturally no satellites inside the Fat Man. The instrument cabin on the top only houses some key equipment, communication equipment, electronic control equipment, gyroscopes, detectors...etc.

The following power system adopts a dual-engine design, one anti-gravity engine and one jet engine. The fuel uses liquefied hydrogen and oxygen. The fuel density is suitable, the calorific value is high, and the combustion performance is good. Complete combustion, and the combustion area is small, the burning waste is water, and will not coke.

Of course, although the combustion of hydrogen and oxygen can produce huge calorific value, it has very high requirements for the purity of hydrogen and oxygen, which is almost 100%. The previous experiments of Qingquan Technology were because the purity was not enough, resulting in unstable combustion and a huge explosion. .

Fortunately, the fat man of Qingquan Technology is an experimental product, and because of the anti-gravity engine design, coupled with the first-level overall design, the fuel inside is not much, and Qingquan Technology has also made comprehensive preparations, so there is no cause. What a big loss, just set off a large fireworks.

Speaking of the previous 8 experiments, three times were because the fuel purity was not high enough, the combustion was unstable, and the explosion occurred shortly after liftoff. The second time was because it flew into the sky and exploded due to the problem of the internal support, and the fireworks were set off five times in a row. In the next three times, the fireworks were finally stopped, and it was able to lift off smoothly and reach the predetermined design speed and height. However, the falling speed was not well controlled during the return and recovery process, and the whole fat man fell into pieces.

Everyone is in place, the countdown to launch! 10! 9!....3! 2! 1! Launch! As Liu Qingquan said the word launching, the staff who had been ready for a long time, gently pressed the red launch. button.

On the launch pad in the middle of the field, a heat wave erupted instantly, red flames emerged from the bottom of Fat Man, and then Fat Man slowly started to lift off.

As the flame slowly turned from orange to red and then to scorching white, Fatty's rocket speed became faster and faster. The fairing at the top was like a Buddha bullet, which cut through the thick air and formed a beautiful cyclone.

At the bottom of the rocket, the long white tail flame is more than ten meters long, and the high temperature generated is as high as 4,000 degrees Celsius. Because the tail of the rocket is close to the root of the flame, it should be low, using a metal-ceramic composite material. It is mixed with metal powder evenly, and then sintered at high temperature to make cermet, which is hard and tough, with low density and high temperature resistance.

Looking at the rocket that had gradually disappeared from view, Liu Qingquan turned around and looked at the huge display next to it. The various data of the rocket were listed in great detail and were being updated at any time.

The altitude is 20,000 meters, the speed is Mach 30 or 10.2 km/s, which exceeds the first cosmic speed of 7.9 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 fuel remains 80%.... . Items of data are constantly changing, and the comprehensive status display is always green, which means that the data is perfect.

The communication team reports the communication situation, Liu Qingquan said as he picked up the walkie-talkie.

The quality of electromagnetic wave communication is poor, and quantum communication is normal. Zhou Jingbo's proud voice came from the walkie-talkie.

Report by the radar team Liu Qingquan continued to ask.

The situation is normal and can be tracked normally

...

Soon, the Fat Man rocket flew out of the stratosphere and came to the upper atmosphere. At this time, as long as it continued to fly into outer space, it would soon reach the height of the launch of low-altitude satellites.

However, today's Fatty 9 is a test product, and it is not ready to fly to outer space at all. It is basically a successful test to reach this altitude, if it is only used as a one-time rocket.

What Qingquan Technology wants is a recyclable rocket. Naturally, there are more difficult considerations behind it. The launch can only be considered half of the success, and the remaining half, the intact recovery rocket is the real problem.

The rocket returns, all teams please pay attention Liu Qingquan ordered the rocket to return after watching the rocket reach the predetermined altitude.

To get rid of gravity when launching, it consumes a lot of fuel. If you return to the flight, you can completely turn off the reaction motor and use gravity to attract the rocket.

I saw the fat man with his head down, flying down like a shooting star, bringing up a long fire, this time is actually quite dangerous, because if the control is not accurate, a comet will come to install the earth, causing damage to the ground below. Huge damage, the loss is unimaginable.

Fortunately, Fatty was controlled very accurately. When he descended to an altitude of 10,000 meters, the two engines were re-ignited and started. With the work of the anti-gravity engine, the speed of Fatty's fall was significantly reduced in an instant, and then he fell quickly. speed slowed down.

At the same time, under the adjustment of the tail of the jet engine, the whole fat man slowly turned from head down to horizontal, and then after flying sideways for a certain distance, the head turned upward, just like when it was launched.

This step can be said to be the most critical step for recoverable rockets. The key to success and failure is to see if the rocket can change its direction and turn its tail downward, because only the tail is downward, and the jet engine can slowly reduce the falling speed, and finally Reach safe recovery.

Fat Man No. 9 faces upwards. With the work of both the anti-gravity engine and the jet engine, the height is slowly lowered. At the same time, according to the position of the fat man, the landing direction is constantly adjusted through the tail.

Soon, Fatty reappeared in everyone's field of vision. Above the field, Fatty No. 9 slowly aimed at the launch pad and landed slowly. The flame at the tail also slowly changed from white to orange, and then Fatty slowly landed. On the launch pad, the engines were all shut down.

Yeah~~~ We succeeded In an instant, whether it was the console or the tracking platform, everyone cheered, and even Liu Qingquan was dancing with excitement like a child!
