Mastering the retail channel is almost mastering the lifeblood of the production enterprise. Other companies may not dare to block European and American products for the sake of international reputation. Even the state does not dare to do this. But Changsheng Investment Group is different, it does not have these concerns, and it has long been on the same page as Europe and the United States anyway. Therefore, as soon as the spring trade mastered the main retail market in China, Shen Danqing ordered a ban on European and American products. Among them, the products of foreign-funded factories in China, and even the products of Sino-foreign joint ventures that are proud to lick Europe and the United States are also prohibited.

Of course, the products of domestic enterprises must also meet the quality inspection standards of Changsheng laboratory. This, with a mandatory order, otherwise the products of the enterprise will not be sold.

Quality is the foundation of the entire Changsheng Investment Group, and it is the magic weapon for it to defeat the enemy, and Shen Danqing has no feelings to talk about. But at the same time, it has also improved the quality of domestic goods, so that their products have strong competitiveness even if they are exported abroad.

Some companies made fraud, saying that their products had obtained the quality standard certification of Changsheng Laboratory, and after Changsheng Investment Group knew about it, not only Dingtian Law Firm was responsible for pursuing responsibility and demanding huge compensation. Moreover, through the media to publicize to the public, all products that have passed the quality inspection standard certification of Changsheng Laboratory will be sold in Spring Department Store and Spring Chain Supermarket, and will never be sold in other informal retail channels.

After such a rectification, the sales of foreign-funded enterprises' products in China showed a straight line diving mode, and all of them lost money.

These companies sued Spring Trading for suspected monopoly and unfair commercial competition, and Spring Trading responded positively: before Europe and the United States have not lifted the unfair sanctions against Changsheng Investment Group, Spring Trading has the right to refuse to cooperate with foreign-funded enterprises, not targeting a specific enterprise.

The response of Spring Commerce and Trade is justified and unjustified, and has won wide support from the people of the whole country. Is it true that only the state officials are allowed to set fires, and the people are not allowed to light lamps? Europe and the United States are at a loss, so it is no wonder that the spring trade will treat them differently.

In this move, Shen Danqing played a wonderful game to the peak, which severely hit the dream of European and American companies to make money in China, and at the same time supported a number of domestic brand enterprises. Through the publicity of the past few years, the quality inspection standard of Changsheng laboratory is very hard and has been widely recognized by the international community. All products that have obtained the quality inspection standard certification of Changsheng Laboratory are well-known brand-name products, which are much higher than the national standards and have more brand reputation.

This practice of spring commerce and trade is a corporate behavior, which cannot rise to the height of the national policy level, and there is no excuse for Europe and the United States to find trouble with China, because everyone knows that Changsheng Investment Group does not deal with Europe and the United States, and their special targeting behavior is normal.

In addition to spring commerce, the fastest growing is Changsheng Construction Engineering. After several years of development, Changsheng Construction Engineering has more than 100,000 employees, in addition to Changsheng Investment Group's own projects, they also actively participate in the domestic infrastructure construction.

The reason why there are only so many people is that they dare not add too much, so as not to cause a heavy burden on themselves. In fact, China's two-stage high-speed railway project and urban public transportation aerial tunnel system project, two trillion-level projects, are far from manpower. The vast majority of them are state-owned large-scale infrastructure groups under construction, and Changsheng Construction Engineering is only responsible for quality supervision and a small part of the project.

Changsheng Construction Engineering's employees are for life, unlike other companies that hire temporary workers and migrant workers, and they have to consider the situation that after the project is completed, the employees have nothing to do.

In general, Changsheng Investment Group is developing synchronously with the rapid development of the country, and has not stopped the pace of development for a moment.

At present, Shen Danqing's main energy is still in military farming. After the successful development of the two stars, Shen Danqing focused on the sixth-generation aircraft. Because of the two global satellite networks, it is necessary to rely on sixth-generation aircraft to deploy.

The sixth-generation aircraft is very important, not only that Changsheng Investment Group has as many as 50,000 engineers working hard to tackle key problems, but also that the state has sent scientists to assist in the development.

The sixth-generation aircraft is a strategic aircraft, a heavy twin-engine fighter-bomber between a bomber and a fighter, and it is also the only aerospace aircraft in the world that can carry out strategic strikes and tactical missions. Its cruising altitude has reached the outer circle of the atmosphere, which is an ultra-rarefied atmosphere and a forbidden place for ordinary aircraft. Reaching a record altitude of 500 kilometres to 1,000 kilometres, all missiles are unsolvable against it, and it can come and go freely in the airspace of other countries.

Three years have passed, and the first R&D project, a new shaftless engine, has been successfully developed. It was not difficult to develop, as it was fairly simple, and compared to ordinary turbofan engines, it omitted a complex movement. Strictly speaking, it is a creative invention. It is a combination of several classical aero engine theories and is powerful. However, its disadvantages are also obvious, that is, it cannot self-start, and it needs to have a high-performance in-wheel motor and a high-performance battery. Changsheng Investment Group also met this technical requirement after the successful development of the second-generation new material battery. Therefore, it is difficult for other countries to imitate, and of course, Shen Danqing will never let this new engine technology leak out.

The real problem is the airframe, which is the only unmanned fighter in the world, and its degree of intelligence is quite high, compared to it, the excess fly-by-wire control system is as simple as a toy. This is a difficult problem in terms of electronic hardware, mechanical control and software.

The second is the casing, because its speed in the atmosphere exceeds six times the speed of sound, ordinary aviation lead alloy materials are far from qualified. Because the speed is fast, the surface temperature of the fuselage will rise rapidly, and the aviation aluminum alloy material may spontaneously combust. Even the stainless steel materials and titanium alloy materials invented in the former Soviet Union are not qualified, and only new carbon fiber ceramic composite materials are used.

This new material, the Institute of Non-metallic Research began to study a few years ago, and it was not until this year, because of Shen Danqing's attention, that a historic breakthrough was made after adding a large number of scientific research forces.

This material, it is lightweight, only about one-tenth of the weight of aluminum alloy material. High strength, three times that of ordinary steel. The most important thing is that it can withstand high temperatures of more than 3,000 degrees without deformation and softening. It's the best material for the body, and the only drawback is that it's too expensive, almost as much as gold. Therefore, it cannot be used in other aircraft, and it is the royal material of the sixth generation aircraft.

The final challenge for the sixth-generation aircraft is the airframe design, which is significantly different from the ordinary fighter due to its speed. Wing-body fusion technology was not enough to meet its needs, and its wing became an exaggerated backward sweep of only 15 degrees. The machine is very small, only half the size of the general fifth-generation aircraft.

Such a design meets the needs of hypersonic flight, but at the same time it also poses two problems. The first is the maneuverability of the aircraft, and the second is the difficulty of the aircraft when landing.

Therefore, this kind of aircraft can no longer be operated manually. Because its machine is too small, and it reaches the rear of the plane, and it is a single vertical tail. All of these designs seem to be deliberately embarrassing, and humans can't control this kind of aircraft at all.

Only the subtle manipulation of the computer can make it fly normally and do limited evasive actions. It's easy to say, but scientists need to calculate, design, and conduct a lot of experiments to improve it.

Even the control is so difficult, and the landing is even more difficult. This kind of aircraft shape design is considered for high-speed flight, and the speed of landing is not so fast, which creates a great contradiction, the plane may be planted like a stone, because its wings do not have such a large lift, can not support the body weighing more than 20 tons.

At this time, the computer is not enough to perform subtle manipulation, and other technologies must be helped. The first is the design of the air-fluid shape of the aircraft, so that the upper part of the aircraft and the lower part of the air produce an air pressure difference, and use the lift of the air to support a part of the weight of the aircraft. There is also the use of the characteristics of the aircraft engine, after the aircraft is turned off, the tail nozzle is controlled, so that the air enters the engine after the great resistance, which is a controllable resistance, which is adjusted by the closure degree of the tail nozzle.

Neither of the above methods can be done manually, that is, you don't even need a pilot to land. In terms of aircraft control alone, it does not require a pilot. But it also has a cockpit, and the pilot is not responsible for piloting, but transforms into a commander for target determination and strike judgment. In this regard, computers are not as good as people, and sometimes they can cause misjudgments.

Another challenge is the airborne radar, which is an expensive strategic aircraft and a heavy twin-engine stealth fighter. First of all, it cannot expose itself, the active radar does not fit, eliminated.

Therefore, it can only be a passive radar that has recently been valued by countries around the world. The passive radar itself does not emit electromagnetic signals, it is a new type of radar that detects the enemy by emitting electromagnetic signals from unrelated sources of third-party emissions. It does not emit signals on its own, so it is difficult to be detected by the enemy, and it is a new radar that is most suitable for stealth aircraft.

This third-party irrelevant emission source generally refers to its ground-based air defense radar, electronic warfare aircraft, air police command aircraft, and reconnaissance satellites and communications satellites located in space.

If the electromagnetic waves in the air are compared to the calm surface of the water, if there is an unknown flying object intruding or passing by, it will leave traces to a greater or lesser extent, and after computer calculations, it can even calculate the shape, size and number of aircraft.

As you can see, this new radar requires a high-performance computer, otherwise it would not be possible to complete such a large amount of calculations. This is already a huge problem for other countries, but Changsheng Investment Group is clearly not one of them.

There are still many problems with the sixth-generation aircraft, but fortunately, Changsheng Investment Group is in research and development, Shen Danqing spares no expense in capital and manpower, according to Shen Danqing's estimate, it may take two years to be successfully developed. If it is replaced by a country, its R&D cycle will be extended exponentially, and it may take more than 20 years to do so.
