This time, it was a real big submarine. Without weapons, it was just treating the submarine as a luxury big yacht, and it was just able to dive. The various luxurious decorations inside were arranged, and all kinds of shocking and decorative, which were contrary to common sense but could extremely show luxury. For example, the swimming pool in the cabin was so stunned that it was so dazzling that it opened its eyes.

Can't you swim in the sea? Of course, you can, but you have to build a swimming pool on the yacht. This is style and taste! But what's the point of a yacht? I built a swimming pool in a submarine and enjoyed leisurely swimming hundreds of meters underwater. Have you seen it? Have you heard of it? I don't know where the swimming pool is better than your yacht.

When the domestic designers in the design company saw this request, they first found it absurd. But they didn't say anything more, because although the interior decoration was incredible, it was a real large submarine with a displacement of 6,000 tons. Although it was a civilian submarine, Guo Tailai still required it far beyond the safety of ordinary submarines. This would inevitably make a big breakthrough in the shell structure materials and technology, and it was also a rare experience for conventional large submarines to be built in China in the future. Therefore, no matter how unreasonable they felt, they would work hard to complete it.

The group of design experts sponsored by several other countries did not feel as incredible as domestic designers, but instead had a shiny feeling. Although this private submarine was unprecedented, it was definitely unique and had a unique luxury.

You should know that some foreign wealthy people, especially a large group of dog families in the Middle East, lie in the pile of dollars when they are born, and their lives seem to be left with all kinds of luxurious enjoyment and unique display of wealth. Haven’t you seen all kinds of big cats that are powerful all over the world, such as lions and tigers, just pets around a group of princes and princes? The more expensive, the more luxurious they are, and the more novel and creative toys they like.

In this regard, the boss seems to have mastered the essence! Look at the supercars and watches he designed before, they are almost all the targets of these wealthy and wealthy families! Isn’t the small submarine the same starting point? Now that more than 100 ships can be sold all over the world, that is a clear proof!

That's just a small submarine. The boss's current big submarine is definitely a big guy that can make the kings and chiefs tempt! Why not? They are different from people in China. Since the boss might have a big market for what he thinks of, they will definitely make great efforts for the boss's generous bonus. In the past, they were military submarine design experts, but now they are civilians, and they don't have to consider weapons or radar, or something. That's not a good idea?

As for the extremely high safety requirements of the boss, this is very normal. If the safety cannot be guaranteed by hundreds of meters underwater, who would buy it? Rich people don’t have to take risks when they are full. The richer they are, the more they cherish their lives. The higher the boss’s requirements, the better the market in the future!

In the past, I designed small submarines, to be honest, these experts thought it was a bit of a big deal. A small thing with a displacement of three or four hundred tons is worth fighting? In the past, it was just a waste of talent and anti-aircraft guns to kill mosquitoes. Now it’s great. A big thing of 6,000 tons, the largest conventional submarine in the world’s navy is this displacement, which is enough for them to show off their creativity. When they see the boss’ request, they wish they could shout long live immediately and rush out to work.

What remains is the group of Ukrainian "migrant workers". They have unambiguous requirements for their bosses. The boss greets them with delicious food, drink and living, which is many times better than their life in Ukraine. And they go out every day and don't have to worry about whether they will be robbed by gunmen who suddenly appear on the road. This is simply paradise! Who brought this heavenly life? Isn't it the boss? The boss's request is their goal, and it is absolutely true.

Relatively speaking, the helicopter project team next door is more difficult. A helicopter has been designed for several years and is constantly being improved. There is no way, it is difficult for an aircraft to apply for an airworthiness certificate than a submarine or a yacht, and the safety requirements are higher, so it is inevitable to take a long time.

However, even so, the overall development process of the three-fan helicopter designed by Guo Tailai, which he himself nicknamed "small three-wheelers in the air" or "three-bouncer in the air" was still very smooth. After all, the engine is a mature and reliable engine, so there is no need to worry about this issue. Just consider the safety and handling in the air.

Guo Tailai's speed required is only more than 600 kilometers per hour, which is not high and easy for a plane that can fly horizontally. The highest difficulty is the handling of the three fans, the rotation and balance of the duct fan when taking off and landing.

After all these problems are solved, the rest is actually a large number of flight tests. This test process makes the domestic team that is also developing helicopters so envious. How can the domestic design team have such a luxurious flight test? Even if it is just a helicopter, every take-off and landing test may not be missing hundreds of thousands of dollars. Therefore, the domestic team is very frugal, and all kinds of problems are considered, and they will only be tested after they are solved safely.

But Guo Tailai's planes do not regard money as money, and have test flight missions almost every day. Before, they were just one prototype. After testing for a long enough time and meeting the safety and stability requirements, they actually built two more aircraft, three of which flew together. Three prototypes a total of at least fifteen hours of flight tests every day. Not to mention the fuel and losses during the flight and the subsequent maintenance costs, just the experienced test pilots took turns to test and experience each aircraft and took turns to give suggestions. This cost is not something the project team can easily bear.

However, such a large number of frequent tests have great benefits. On the one hand, the longer the flight time, the more detailed and comprehensive the problems found will be. On the other hand, different test pilots have different experiences, and sometimes they can find some problems that others cannot find. The more problems they find, the more they can promote the project team to improve and modify, which in turn promotes the overall progress.

There is a very important reason for the rapid progress. Guo Tailai is a civil aircraft. After applying for various patents, he doesn't have to worry about leaking secrets or something. Anyway, the engine is a mature American product, but its unique appearance and flight design can be tested in a swagger. At least it has been tested on the southernmost and northernmost in China and even on the plateau. The product is almost fully mature, and it is only a short flight certificate.

The domestic airworthiness certificate is obviously fine. The test pilot is a group of retired pilots recruited by Guo Tailai for a high salary. During the test flight, there are even military personnel accompanying the accompanying records, and various modifications are all filed at the Changhe Aircraft Manufacturing Factory. The core secrets are not encrypted by the country. The domestic airworthiness certificate will be obtained in June this year at most.

In the United States, a newly produced prototype has been loaded and shipped, waiting for testing in the United States. However, it is not a big problem to use American engines. By the end of the year, this luxury private helicopter can be produced and sold to the outside world.
