Because this shaftless pump propulsion drive device is an all-electric propulsion system, countries around the world are currently in the research stage, mainly for a new drive method used on submarines. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

This drive method is very quiet, and the shaftless paddles do not have to worry about being entangled in debris in the water and losing power.

And the propulsion system that Yang Yu let these senior technicians improve is upgraded from the current technical improvement in this area, although it is not a black technology, but there is no doubt that it is definitely the most advanced electric propulsion system in the world.

Because the technology improved by these senior technicians is very mature in all aspects, there is no need to worry about stability and other aspects.

Moreover, this improved shaftless propulsion device, because it can turn 360 degrees, can also completely abandon the huge rudder to control the ship's movement, this 360-degree rotating shaftless pump propulsion device, can control the direction of the hull itself through its own steering.

This method is similar to the vector engine used in a fighter jet, which can be thrust steered through the vector nozzle of the engine, allowing the fighter to make a large maneuver.

For example, if a ship that is going straight requires an emergency turn, simply turn the propulsion unit directly to the left, and the ship can quickly turn to the right.

This steering method is more responsive than the rudder, and it is also possible if the boat is going straight at high speed and wants to reverse quickly.

The electric propulsion unit is also easier to reverse than the traditional gas turbine, steam turbine, or diesel engine, or even directly turn the propulsion device in one direction, which can make the ship reverse quickly.

At present, the first ship that Yang Yu's shipyard wants to build is actually his superyacht, because as the world's top rich, he doesn't even have a yacht of his own, which is quite a loss to say.

Originally, if he needed to, he would have been able to buy a yacht of his own, but since he knew that he had the ability to build it himself, he naturally didn't need to buy it, after all, the spot he bought was second-hand, and letting other shipbuilding companies build it was not as fast as the construction speed he had after building the shipyard himself.

The design work for this yacht has already been completed, and it is a 5-storey yacht with a length of 260 meters and a width of 80 meters, with two helicopter take-off and landing platforms.

In addition to the overall use of alloy frame, combined with super-expanded materials to build the hull, the hull will also be protected and reinforced with a layer of titanium alloy steel plate on the outside of the hull.

Inside the yacht there is also a 10-meter-long and 3-meter-diameter small sightseeing submarine, which is made of all-titanium alloy, because the super expanded material is not suitable for building submarines that are completely submersible.

At the same time, this yacht will also be equipped with a very advanced radar system, after all, this is the yacht that Yang Yu directly wants to sit on, and of course all aspects must be as perfect as possible.

On February 10, Yang Yu received a call from the leader above, saying that the H-11 super-heavy helicopter he launched had completed all the tests, and all the tests had no problems.

Then he also told him that the government needed the first batch of 20 orders, as well as the engine and some other accessories produced by Yang Yu, and hoped that Yang Yu would not sell this helicopter to markets outside China for the time being.

Of course, Yang Yu agreed to this condition, because this helicopter can transport most of the heavy weapons and equipment.

And this kind of heavy transport helicopter, the civilian version and the military version are actually not much different, because the version of the civil movement can also lift such a large weight, but there is no special radar system for the military, and some defensive weapons.

At present, the United States and Lao Maozi, who have this kind of similar heavy helicopters in the world, are prohibited from selling heavy equipment to our country, even if our country now has a few Mi-26s, they are only the civilian versions that Lao Maozi sells to us for forest fire fighting and emergency disaster relief.

If we want to buy more for military purposes, Lao Maozi will not agree, and as for the United States, it is even more impossible.

It's just that compared with the United States, Lao Maozi is a little more lax than the United States because of the bad economy.

And now the situation is going to be reversed, because with this H-11 super heavy transport helicopter, it will be our turn to play the embargo.

And Yang Yu's purpose in manufacturing this kind of super-heavy transport helicopter is not to make much money, mainly to reward, so even if it is simply to meet the domestic market, it is okay.

What's more, this embargo also depends on the object, and the leader above also said that it will not be sold to the public for the time being, and it is obvious that there will be no problem in selling small quantities in the future.

Of course, he is definitely selling a civilian version.

However, whether it is a civilian version or a military version manufactured by the military itself through technology, most of the parts and components have to be purchased from Yang Yu's Huanyu Company, because technology is such a thing, it does not mean that with technology and related drawings, it can be thoroughly understood and then made.

For example, although the military now has all the design drawings of the H-11 super-heavy transport helicopter provided by Yang Yu, they want to completely independently manufacture products with the same technical level as Yang Yu's factory, and there are still many problems to be solved, and it will take at least two years for the military to be able to thoroughly understand these technologies.

And at that time, Yang Yu may let his subordinates come up with new planes, so Yang Yu naturally looks down on these technologies that are only slightly ahead of the current level of science and technology.

At present, the price of this helicopter Yang Yuwai government is 150 million yuan, which is completely internal, and the external price has not yet been determined, but at least it must be doubled or doubled on this basis.

And these orders from the government are both military and civilian, because although the factory is civilian, it is still possible to be repainted, directly retrofitted with some other military equipment, and then used for military purposes.

After all, although the military now has the technology, they can't make it completely in a short period of time, so they definitely need to buy a small batch through Huanyu for military use.

Because it involves military equipment and weapons, it is unlikely that it will be handed over to a private company based on the national conditions of our country.
