The fifth update of the first and fourth chapters of the landing weapon (II) is completed in 15,000 words

It seems that this discussion boom has triggered the military's conversation, and another general has also taken the conversation, but this guy is obviously a technical stream, so as soon as he speaks, he goes directly to the topic from a technical point of view.

"From a technical point of view, the performance of the 'European Bison' hovercraft is remarkable, and this kind of giant of more than 500 tons is difficult for the US imperialists to take. The Bison is extremely difficult to build, I remember that when Greece bought this type of hovercraft, even the shipyards that produced the European Bison hovercraft initially refused to build it en masse, because they had to face a bunch of aviation technology and were incapable; Aircraft factories are even more difficult, because military ships are demanding, and they cannot be equipped with thin-skinned and large-stuffed aluminum-skinned empty shell aircraft. ”

"The second difficulty is the need for hulls that are light enough and strong enough, and the Soviets are doing more perverted things than the US imperialists, such as building submarines out of titanium alloy, which has never been done before, and there are no plans to build them in the next few decades. The Bison used high-strength aluminum-magnesium alloys to build their hulls, which are as rare as titanium, which we can find in spectacle frames and aluminum-magnesium in laptops. ”

"There is only a part of the aluminum-magnesium alloy shell of high-end notebooks, because of the high price, there are very few all-aluminum-magnesium shell notebooks. Even so, the strength of the aluminum-magnesium shell of the notebook is too poor, and the fat man of two hundred catties can give the Apple notebook that uses aluminum-magnesium alloy and is known as extremely strong, and the civilian products are reluctant to use high-strength aluminum and magnesium. The strength is high, the manufacturing is annoying, and it requires large-scale special equipment to handle this material, and there are a lot of troubles such as welding and maintenance waiting in the back. ”

"The third difficulty is the apron. The apron is sealed on all sides and inflated inside, lifting the hovercraft out of the water. When driving at high speeds, the apron must constantly hit the waves; Driving on land will hit rocks, mounds of dirt or something, and it will not work if it is not strong. The larger the hovercraft, the more difficult the apron technique is. ”

"At the same time, the life of the apron is also relatively short, and the natural wear and tear is relatively large. Although it is easy to repair an apron, it is expensive and every repair is sky-high. ”

"These three major technical difficulties are difficult to overcome in a short period of time," said this, the technical expert sighed helplessly, "but speaking of which, in fact, the bison of the Ukrainians is not a good product, after all, it is an outdated technology from the 80s." The first is that it is okay not to use an aluminum-magnesium shell, there are alternatives; The second is that the engine is so bad, the Soviets have never made a first-class naval engine, not to mention that it is the 21st century. Speaking of this, the general couldn't help laughing at himself, "Of course, we are not qualified to say that people in Ukraine, our naval engine technology is even worse, and we have not made a high-power gas turbine so far, all of them are bought." ”

Zhang Lan was also silent for a while, whether it is in the military or in the civilian field, the engine problem has always been a Chinese person's heart disease, and there is no engine with better performance, which is really terrible

The great value of bison lies in combat, such as fighting pirates, anti-smuggling, and dealing with Dafei, which is easy and effective; Sea rescue and coastal defense frontline emergency supply are also very useful; But in everyday situations, there is no need to invite the great god of bison.

Although bison is a panacea, the price of ginseng is unaffordable. Generally speaking, buying a two-headed boat and then transferring it to build it can be 30% cheaper. It is estimated that the current unit price of bison is around 90 million RB, and now the military and the Ukrainian side are talking about the purchase of production licenses plus some technology transfer.

However, only to improve the design and production requires a full set of technology transfer, and this cost is amortized into the construction cost, which is always more expensive than buying a license to build, and there is no comparison. Of course, purely from the perspective of purchasing technology, it is really not expensive for the Ukrainians to offer 240 million US dollars even for the technical belt 4 too European bison, and at this price, Ukraine vomited blood.

For the Ukrainians, they also see very well that now the technology of the European Bison hovercraft still has the value of a fire sale, and with the advancement of technology, more and more people want it, and if possible, simply sell it.

Similarly, Zhang Lan estimated that before the military and the Ukrainian side negotiated the purchase of European bison hovercraft, the domestic military bought bison fake, and the full set of technology to buy bison was real; Buying technology is fake, establishing a large hovercraft R&D system and building your own hovercraft fleet is real.

For this card, the country really went around in a big circle, and it took a lot of painstaking work.

If the European Bison hovercraft is converted into a Bison missile attack boat, the Bison missile attack boat is much stronger than the ordinary missile boat, and the enemy fleet will consciously fight outside the Bison attack circle. ,

The Bison is extremely maneuverable, so if possible, the shore-to-ship missile force can be reduced by a significant part. Like the shore defense artillery, the combat area suitable for shore-to-ship missiles is very narrow, and most of them are defenses with fixed points, which can be replaced by missile speedboats, and with Bison, most of them can be replaced.

The reason for the survival of shore-to-ship missiles is mobile warfare, the reason why missile boats replace shore-to-ship missiles is that they are more mobile, and the reason why Bison replaces missile boats is the same, and they have the strongest maneuverability.

The Bison patrol boat is very easy to use, with the 7 naval guns commonly equipped on the frigates of the domestic navy, the firepower is already very powerful; Running up to 60 knots, faster than the big flight of smugglers; Whether it is piracy, smuggling or enemy boats, they are all fodder.

The landing transport ships are very good, they can quickly replenish the island troops, and they can also afford things like sea rescue in peacetime.

Minesweeping and minelaying are the advantages of hovercraft, and there is even more reason to build a batch. You can even develop some quirky bison ships, such as helicopter motherships.

Helicopters are the silver bullet of the Navy, they can do anything, helicopters are the same as Bison, the disadvantage is that the legs are short, the two short legs are put together, the legs are much longer, and the Bison platform is a good idea to carry a helicopter. If the Taiwan Strait operation lacks the direct cover of armed helicopters, the Bison helicopter mother boat will be able to make up for the vacancy; if we develop a small helicopter sightboat on the basis of the hovercraft we have developed now, and we don't want how fast it can run, what will be the result......

"What are you doing?" Just as Zhang Lan was immersed in his thoughts, a person came over and pushed him.

"Huh? What's wrong? Zhang Lan, who was immersed in his own thoughts, was stunned for a moment, and when she heard this familiar voice, she hurriedly looked up, only to find that it was Elaine who pushed her.

"What's wrong? Everyone got off the plane, and they were waiting for you," Elaine's voice was a little dissatisfied, "I was waiting for you, but I didn't expect you to be in a ...... for so long"

What? Everyone got off the plane? Zhang Lan was stunned for a moment, and hurriedly looked up, but the cabin was empty now, the bright sunlight outside was shining in from the cabin door, and the bright light made the milky white leather massage seat a little hazy, except for himself and Elaine, there was no one?

"Like the basic structure of almost all advanced hovercraft, the AI-600 hovercraft developed by our Alice Group also uses a propulsion fan drive."

When Zhang Lan and Elaine walked into the design room, Jill was there to introduce the technical characteristics of the AI-600 hovercraft to the generals of the military, in the middle of the design room, through the three-dimensional projection equipment projected by the Alice Group The simulation design of the AI-600 hovercraft was slowly rotating, and when Jill said that place, the design drawing automatically switched to the details of that place, which was simply lifelike, of course, It also shocked the "soil buns" who came to Alice Group for the first time.

Jill, on the other hand, was pointing to the three-dimensional design of the AI-600 hovercraft and gushing

"The rear of the AI-600 hovercraft is equipped with three propulsion fans, which can be reversed, fixed at the rear of the hull with an upright bracket, and driven by hydrogen fuel cells in accordance with the requirements of the military. The electricity provided by the fuel cell drives electric motors to drive cushion blowers and propulsion fans to propel the hovercraft forward. In terms of performance, it fully meets your requirements, with a cruising speed of 55 knots and a top speed of 60 knots. ”

In addition, in addition to the main power system, there are two fuel cell packs, each with a rated power of 100 kilowatts. Ship control and system operation is operated via 1 main console, 1 central control room and via a variety of different remote control dashboards. ”

Like the Russian "European Bison" class air-cushion landing ship, the design adopts a square pontoon structure, and the square pontoon structure of the AI-600 hovercraft hull can provide the hovercraft with a sturdy, stable, and seaworthy design. ”

"The pontoon superstructure is divided into three functional areas by two longitudinal partitions. The middle functional area is used for the landing of armored vehicles, using glide tracks and ramps for loading and unloading work. One of the two external functional areas is the main and auxiliary power room, and the other is the amphibious force cabin, the crew living module and the life support module, which have NBC (nuclear, biological and chemical) protection capabilities, of which the crew living module accounts for a quarter. Ventilation, air conditioning and heating units are installed in the transport compartment and crew living compartment, and these functional areas also have thermal insulation, noise isolation layers and vibration isolation structures. The hull of the "European Bison"-class air-cushion landing craft is covered with lightly armored hull plates, which has a certain degree of protection against ammunition and explosive fragmentation. ”

"As for the weapon system, I have already introduced it to you before, so I won't introduce it here, the electronic system and navigation system are provided by you, and the performance is better than us, so I won't make an axe in front of you, here, I solemnly introduce to you a new technology applied by our Alice Group to the AI-600 hovercraft" Speaking of this, Jill looked around proudly, and saw that the generals of the military all turned their attention to their side with bated breath, and smiled with satisfaction," A new stealth technology for hovercraft"

Hovercraft stealth?

As soon as Jill's words came out, the entire design room suddenly fell silent
