Recently, there has been a wave of industrial exploration on the Internet, and it is becoming more and more mysterious, but is the fact as reported by the media? Is it a treasure that has been found out in the end, or has it been fabricated by the media as a contemporary "hand-tossed devil"?
The simple story is that the mainland has always believed that it has been "stuck" by foreign countries in many technologies, but it was found after a thorough investigation of the country. You guys are really more able to hide than one another, and each hand holds what I want and is silent.
In this regard, some netizens commented: "The villagers shared the controllable nuclear fusion technology with you." It can be described as an industrial survey, you can touch it, and you will not squeak when you touch it.
Among the reports of the big survey, the "three King Kongs" attract the most people's attention and make people feel the most excited, among which are the aircraft carrier blocking cable produced by Juli Group, the carbon fiber produced by Guangwei Technology, and the delivery drone cooperated by Tengdun and SF Express.
At the time when the three King Kongs were all over the Internet, various versions appeared, what the dock mooring line commissioned by the United States to be manufactured by the mainland was actually an aircraft carrier blocking cable, and when I found out, there were thousands of warehouses!
Phased array radar is used to drive wild boars, SF delivery drones are "cut off" by the military, car owners buy Guangqi's car paint and escape the speeding camera, etc.
Although it is true and false, it is enough to make netizens enthusiastic, or they would not have said that the industrial situation is the bottom of the world, and the great powers are actually myself.
But did many of the mainland's technologies really break through the technological blockade as easily as they reported? Or did most of the reports just come out of nowhere?
The delivery drone becomes Global Hawk Pro in seconds
As one of the two best express companies in the mainland, SF Express has always wanted to "flip" JD.com and become the leader of the express delivery industry in the mainland.
However, Jingdong's urban warehouse SF cannot be copied, and even if it is copied, it can't catch up with Jingdong, which has so many years of experience, so choose another road, and finally choose the drone delivery business.
In order to realize this project, SF Express has teamed up with Tengdun, a leading large-scale drone company in mainland China, to develop large-scale delivery drones. SF's demand is one ton of carrying capacity and a maximum range of 3,000 kilometers.
After more than a year of research and development, this thing really came up for him. The drone, called the twin-tailed scorpion, has a maximum load capacity of one ton, a range of 35 hours, a top speed of 300 kilometers per hour, and a maximum range of 3,500 kilometers. Far exceeds the initial needs of SF, but the CEO of SF is bad, and he can overturn Jingdong with the twin-tailed scorpion drone.
It turned out that the mainland air force also took a fancy to the twin-tailed scorpion, and wouldn't it be fragrant to use such a good plane to drop bombs? What kind of express delivery is "no future". Under the "flickering" of the mainland air force, SF Express overturned JD.com's "big killer" and was abducted by the air force.
After the twin-tailed scorpion entered the army, it was transformed by the military industry, and the range was directly upgraded to 8,000 kilometers, with a maximum load of 2.8 tons.
Not only that, each cost 200w, which is really cheap for an unmanned bomber, and it is impossible to imagine what kind of improvement it will be for the continental air force after mass production. SF Express not only sent the twin-tailed scorpion, but also sent the technicians and technical data of the UAV jointly developed with Tengdun, which shows its contribution to the country.
The angler holds the same carbon fiber as the plane?
When it comes to fishing gear, everyone must first think of the mainland's Guangwei fishing gear, and he is also one of the suppliers of carbon fiber materials for mainland fighter jets. Guangwei fishing gear was a small fishing rod factory in Weihai at the beginning, and it was a fishing rod OEM business at the beginning, and later the boss Chen Guangwei began to develop its own products in order to break the monopoly of high-end fishing rods.
Later, while studying in Japan, Chen Guangwei discovered that fishing rods can be used not only glass fiber, but also carbon fiber. Compared with glass fiber, carbon fiber is lighter in weight with the same performance and strength, which is more suitable for anglers' fanatical pursuit of rod performance. But later, due to the tension in international relations, there was a problem with the import of carbon fiber.
Guangwei boss Chen Guangwei and his son Chen Liang after continuous efforts and patient explanation, finally persuaded the Japanese equipment manufacturer to agree to the introduction of this batch of equipment, but the US government still did not agree to use the machine for the military industry, in the end after the investigation Chen Guangwei father and son did not have a military background, only to rest assured that the second-hand wide carbon fiber prepreg production line was delivered to Guangwei Group.
Although the equipment is available, the Japanese side has not disclosed the relevant technology and operation methods, and can only slowly explore it on its own. After decades of exploration and research, he successfully developed the domestic T300 grade carbon fiber, and with the continuous maturity and research of technology, Chen Guangwei began to use technology to help the country.
With this determination, the transformation of the military industry began to vigorously develop high-strength carbon fiber, and the money earned from selling fishing gear was basically invested in research and development.
It is a pity that this outstanding patriotic entrepreneur Chen Guangwei died of illness in 2017 and did not see the mainland's carbon fiber industry reach the top of the world. His son Chen Liang continues to contribute to the country's carbon fiber demand with his dream!
Really "overtaking in corners"
There are many countries in the world that have aircraft carriers, and there are also many carrier-based aircraft that have started ejection, but there are only two continents and the United States, which have started electromagnetic catapulting.
Although the United States has it, they don't understand it very well. The USS Ford's electromagnetic catapult was repaired for longer than it was in service. Other countries also have catapults, but they are basically neat catapults with extremely unstable output, which is not comparable to electromagnetic catapults.
However, Ye Lezhi's research team in mechanical and energy engineering at Beijing University of Technology in mainland China has been working day and night on the new ejection system. In a paper on electromagnetic ejection published by Ye Lezhi's team in March, a new system with a small size, simple structure, and no need for complex power supply was mentioned.
The performance of the new system is extremely high, it can push a 30-ton aircraft to accelerate from 0 to 70 meters per second in 2.1 seconds, and the mainland's most advanced J-20 fighter is also about 15 tons, with a full load of about 25 tons, and a 13-ton aircraft can only accelerate to 66 meters per second on the current Fujian ship's catapult system, and it takes more than 3 seconds to accelerate.
In this way, it can be seen that once the new system is put into use, the take-off weight and speed of the mainland's carrier-based aircraft will be greatly improved, and it can not only eject and start, but also block and slow down, and can slow down the aircraft from 72 meters per second to 0 in 2.6 seconds.
Because of the small size and simple structure, the failure rate of the new system is greatly reduced, after all, the simpler the structure is the more reliable from ancient times to the present.
This also means that if necessary, carrier-based aircraft can not only take off from aircraft carriers, but other warships can also take off and land carrier-based aircraft. This will break the world's existing battle formation strategy against the Navy!
Therefore, it is not all the treasures that have been found, but the military industry and scientific research workers in our country have worked hard day and night to achieve technological breakthroughs, and they are not "easy" breakthroughs as reported by most media.
The most excessive thing is that they describe the breakthrough of technology lightly, so that the work of our scientific research workers who are really deeply engaged in the field of technology is regarded as useless work and eaten for nothing.
I hope you don't criticize our country's scientific research workers because of these media articles with mixed truths and falsehoods, scientific research requires time and trial and error to achieve the goal of calculation step by step in order to produce results, and it is not as easy as the article is written. We need to support them and not make them feel that their efforts are not understood by the public.
