Great warships

Chapter 307 Flying to the sky with asbestos tiles
Chemezov and Misin were completely disappointed. Originally, they planned to make money through the helicopter project. Who would have thought that they had already prepared for it.

If they act as agents and negotiate with customers, they can make more money. However, Mr. Qin in front of him is quite shrewd, and he will definitely not let them act as agents. He bypasses them and talks directly with the Kamov Design Bureau!

They had no other choice but to hand over the choice to the Kamov Design Bureau. However, with such a shrewd operation by Qin Tao, the Kamov Design Bureau should not make much money.

After the modern-level project was thoroughly negotiated, Zheng Ming followed Qin Tao and embarked on the road to the Kamov Design Bureau.

"At present, our navy really needs a helicopter of the Ka-28 level." Zheng Ming said excitedly: "If we can introduce this kind of helicopter, we can quickly make up for the shortcomings of our navy."

Hearing Zheng Ming's words, Qin Tao was also a little emotional: "Yes, now, the tonnage of the Zhijiu we have is too small, and the volume of the Zhiba is too large, so it is inconvenient to operate. If the price is right, our navy will purchase a batch. The Ka-27 is not only used on these two modern-class ships, but can also be used on the destroyers and frigates we will produce in the future to solve our urgent needs."

At that time, the navy did not have carrier-based helicopters at all. In the 70s, the 718 project was launched, that is, the test of launching a long-range launch vehicle into the Pacific Ocean. Helicopters were needed to measure the low-altitude trajectory of the return module, measure the landing point, and search for the return module. salvage.Shipborne helicopter related projects have just begun.

At that time, there was nothing, and it could only be imported. The Hornet helicopter was imported from France to temporarily meet the needs of the navy.After that, I felt that the plane was good, so I introduced technology to produce it, and named it Zhiba.

Now, the localization of Zhiba is still going on, probably at the level of being able to produce more than 50.00% of the parts by itself.

However, because this aircraft is thirteen tons in size, it is very large and can only be used on large warships, such as large decks such as supply ships, flight decks modified from 051, or 052 The deck is simply not big enough.

Therefore, with the introduction of Dolphin helicopters in China, the domestically produced Z-[-] has become the most important ship-borne helicopter for the Navy. At present, almost all newly-produced warships use the Z-[-] as the helicopter to carry it.

This four-ton helicopter is small enough that even a [-]-ton frigate can open up a take-off and landing platform for it to carry. However, the disadvantage is also obvious: the load capacity is too low.

A four-ton helicopter has an empty weight of two tons. Adding fuel, the crew, etc., can carry at most one ton of equipment. Therefore, in actual combat, one with sonar buoys and the other with anti-submarine torpedoes. The two fight together.

A helicopter like the Ka-27 has many advantages.

For example, its maximum take-off weight is 12.6 tons. When performing anti-submarine missions, it often takes off with a weight of more than ten tons, which belongs to the same level as Hezhiba. The length is very small, and the operation is very convenient, even if it is the deck of a [-]-ton frigate, it can fly up.

The only flaw is its height. The coaxial reverse layout makes it very tall. If there is no hangar specially tailored for it, it will not be able to park in it.

If you want to talk about the future of carrier-based helicopters, it is definitely not the Ka-27. This kind of coaxial reverse helicopter is not common after all. In later generations, after the motherland has the advanced Zhi-20, it will be used as the main helicopter. up.

However, it takes time after all, and the current window period can be filled by Ka-27's export model Ka-28.

"President Qin, have you ever been to the Kamov Design Bureau?" Zheng Ming couldn't help asking Qin Tao.

"No, I have been to the Miri Design Bureau and the Kamov Design Bureau. This is the first time. Therefore, I don't know the people there." Qin Tao smiled: "However, after going this time, acknoledged."

Zheng Ming has already seen Qin Tao's communication skills. No matter what kind of old man he is, he can be subdued by Qin Tao's flickering. Naturally, Kamov Design Bureau is no problem.

"The Kamov Design Bureau is also Lao Maozi's old helicopter design bureau!" Zheng Ming sighed again.

"That's right, all the way to Hei's Design Bureau." Qin Tao added.

In the whole world, only the Kamov Design Bureau is engaged in coaxial inversion and continues to do so.

Nikolai Ilyich Kamov, the famous helicopter designer master, was born in Irkutsk, Russia in 1902, and he is from the same hometown as another helicopter giant, Miri. After Kamov graduated from the Tomsk Institute of Technology in 1923, he has been engaged in the research work of autogyro.

In the era when he was just developing, helicopters had just started, and a hundred flowers were blooming. However, after the end of World War II, the general opinion in the world believed that the helicopter with a single rotor and a tail rotor had matured and was the most suitable layout. Helicopters will have no future.

Even Sikorsky, an American helicopter master of Russian origin, thought so, but Kamov did not give up. After he formed the Kamov Design Bureau in 1948, he has been dying on coaxial twin-rotor helicopters.

The propeller on the top of the helicopter needs to rotate, which will give the helicopter a reaction force. In order to counteract this moment, the helicopter needs to put a propeller on the side of the tail to maintain balance. Therefore, when the helicopter is hit by the tail rotor, it will hover come down.

In order to provide a large enough torque, the tail needs to be a distance away from the helicopter body. Therefore, the helicopter body is very long, and the coaxial reversal can avoid this problem.

Since the propeller has a reaction force, then simply add another propeller and turn it in the opposite direction, so that they cancel each other out.No need for empennage, and like this, the length of the helicopter can also be shortened a lot.

In terms of specific comparison, they are also 27-ton helicopters. The length of the Ka-11 is about 19 meters, and the length of the Zhiba is close to [-] meters! (not counting propellers)
On warships where every inch of land is expensive, it is very beneficial to use a coaxial inversion helicopter.At the same time, the two large plates rotate together, and the diameter can be reduced a lot under the same output power.

Of course, although the length is shortened, the height is very high because of the two large plates above the head. However, ordinary warships are only single-story hangars, so the height does not seem to be a big problem.

"Kamov can be regarded as a genius master in the helicopter world." Zheng Ming said with emotion: "By the way, who is the current designer?"

"Now? Sergey Viktovich Mikhaiev, Kamov's student and assistant, heir to Kamov's career."

Mikhaiev stood in front of his helicopter, silently lost in thought.

After catching up with the West, they all changed their dressing styles. Mikhaiev wore a suit, which looked like a Westerner. He was tall and also very wide. The suit was specially fattened, and the buttons could barely be buttoned. On the front, a huge belly sticks out in front, and it looks like there are at least quintuplets.

"Mr. Chief Teacher, the guests have arrived." At this moment, an assistant said to him.

"Bring the guests here."

"bring it here?"

"That's right, bring them here and let them see the most advanced products of our Kamov Design Bureau." Mikhaiev said: "The helicopters we produce are the most advanced in the world!"

"Ok."

Soon, a group of people came over, and when they came to the front, the young guy immediately became excited: "Ka-50? This is much better than Ka-29! Powerful and domineering, yes, if I Choose, I will definitely choose this gunship!"

"You are President Qin?" Mikhaiev looked at Qin Tao.

Qin Tao stretched out his hand: "Yes, it's me, this is the representative of our navy, Zheng, we plan to come and see your shipborne helicopter, but we didn't expect to see this advanced armed helicopter first. Helicopter."

If in Lao Maozi's time, this kind of aircraft would definitely be kept secret, but now, in order to get orders, they have to create momentum to make their aircraft more popular.

Zheng Ming's gaze also looked at this special shaped helicopter, which looked extremely different.

The two large plates on the top are weird enough. The shape below is even more special. The fuselage is short and thick, with short wing pylons on both sides, and anti-tank missiles and rocket launchers hanging on it. It looks like an armed helicopter.

However, professional armed helicopters are two-seaters in tandem, and the one in front of them has one seat. Is this a single-seater armed helicopter?

Ka-50, the ace of the Kamov Design Bureau!
Although they survived by orders from the Navy's carrier-based aircraft, they will not accept only the Navy's carrier-based aircraft market, and they are constantly seeking new breakthroughs.

When the new generation of Western armed helicopters appeared, they knew that the opportunity had come.

Although there are Mi-24 helicopters in China, this armed helicopter modified on the basis of a transport aircraft has a large body and a backward design. It has shown many disadvantages in the Afghan battlefield. The development of a new generation of armed helicopters is imperative.

The Miri Design Bureau produced the Mi-28, and they produced the Ka-50.
The overall design of the aircraft still uses their best layout of coaxial inversion. The body is short and thick, which looks more murderous. At the same time, they also used a single-seat layout for the first time!

The traditional armed helicopter is a two-person pilot system, one pilots the plane and the other operates the weapon system, but the helicopter in front of me has only one person!

Hearing Qin Tao praise this helicopter, Mikhaiev showed a smile on his face: "Yes, we also believe that our armed helicopter is the strongest in this era! If it is not because the Red Empire has collapsed, This helicopter has entered the army in large numbers!"

"Yes, there have been too many changes in the past few years." Qin Tao said: "You not only need advanced helicopters, but also enter them into the international market!"

Why did the other party show good things so generously for Qin Tao and the others to see?Of course it's because the other party wants to sell, since the customer has come, you have to show it!What if you fool around and live in one?

"Yes, we have taken it to an air show, hoping to get more users' attention, are you interested?"

This guy is simply hungry, we are the navy, why do we need the armed helicopters of the Army Aviation Corps?Zheng Ming secretly thought in his heart.

"From a user perspective, it's not perfect."

Hearing Qin Tao's words, the faces of the people present immediately changed, and Mikhaiev also frowned: "You say it's not perfect?"

"Yes." Qin Tao is very generous: "You have made a lot of innovations, especially this single-person driving system, which can save customers the cost of one crew member, but will customers accept it? In a market economy, Everything must be customer-oriented, and in order to meet the needs of different customers, you should develop in a diversified way.”

What do you mean?You guys don't seem to understand.

"Qin, can you be more specific?"

"You can make several more models. In addition to the single-pilot system, there is also a two-person scheme. Moreover, according to the size of your aircraft, not only can you make a tandem two-seater, but you can also do a side-by-side Two-seater. In this way, there are various plans for customers to choose from.” Qin Tao said: “In this way, customers’ needs can be better met. Of course, personally, I still like the two-seater plan. I think, This program has the greatest potential.”

"However, the single-person driving method is the biggest innovation of our aircraft!" A technician said.

"Yes, it is your biggest innovation, and you are still proud of it. However, do customers feel at ease? You do design not to immerse yourself in it and feel very enjoyable, but to gain user recognition. In many cases, the products that win the bidding are definitely not because of innovation, but because of reliability.”

Zheng Ming on the side was a little anxious, what happened to Mr. Qin today?This card is -50, we don't buy it, you can just say a few words of praise, why are you picking on them?Since ancient times, loyal words have been harsh to the ears.

We are here to buy Ka-27. If you offend these people, then the negotiation will be difficult!
Everyone present became serious, especially Mikhaiev, whose face was even more gloomy and terrifying.

Qin Tao didn't care. He walked aside and continued to make up his mind: "Besides, you must not forget your old profession. You are engaged in naval carrier-based aircraft. Although armed helicopters are for breakthroughs, they must also be equipped with naval aircraft. For example, continue to make the top propeller foldable, and the side weapon pylons can also mount naval weapons, anti-ship missiles and so on, the navy will definitely like it.”

"Qin, you are right." Mikhaiev said in silence: "We can't always be immersed in our own inventions and creations. Our designs must be accepted by more customers! In fact, we participated in last year's During the air show, some customers asked us if we could make a two-seater layout, but we refused at that time, but now that we think about it, we were wrong.”

Generally speaking, the top leaders of the design bureau are very stubborn. This Mikhaiev with a big belly looks like a serious person. Unexpectedly, he was actually moved by Qin Tao's few words!

Only Qin Tao knew in his heart that what he said was the truth and the development direction of Ka-50, so these people in front of him would definitely listen.

The single-seater Ka-50 was not sold. Later, it was changed to the side-by-side Ka-52, and the order was obtained. Da Mao is really enough for a bowl of water. Both Ka-52 and Mi-28 , no one is partial, but in actual combat, the Ka-52 is indeed more brilliant than the Mi-28.

They had already been questioned by others at last year's air show, and they had already done a lot of preparation work. Now, Qin Tao, this is just a finishing touch.

As for the ship-borne gunships used by the navy, there is nothing there. Ka-29 has them all, let alone professional ones. When the Ka-52 flies into the sky with Neptune anti-ship missiles, it is truly domineering. .

Now, what Qin Tao said was what the Kamov Design Bureau would do, so it could speak to their hearts!
"By the way, are you here to see the anti-submarine helicopter? I'll take you to see it." Mikhaiev already had an idea of ​​improving the Ka-50 in his heart, and there is no other use for staying here. Let the customer go to see the anti-submarine helicopter.

Just in the workshop of the design bureau, several helicopters lined up there.

From the appearance point of view, they all seem to be the same. The short and thick fuselage looks a little bloated, and there are several vertical tails at the tail, which are also round and bulging, which looks very unique.

It is difficult for laymen to distinguish the models of these aircrafts, but Qin Tao can tell the difference at a glance.

Card-27, Card-29, Card-31?

That's right, the plane on the far side, which is being improved, has a straight glass on the nose and no arc transition. It should be the Ka-29 version, but its fuselage is placed directly on a table. There are a few people below who are studying how to fix the flat-panel radar antenna. Isn't the one with a strip-shaped flat-panel antenna the Ka-31 carrier-based early warning aircraft?

Although Lao Maozi has developed two fixed-wing carrier-based early warning aircraft, with the dismantling of the nuclear-powered aircraft carrier, these are no longer possible. If the existing Kuznetsov wants to have a carrier-based For early warning aircraft, they can only follow the path of early warning helicopters like the British.

The British learned the lessons of the Falklands War and hung a big ball on the side of their Sea King anti-submarine helicopter. Although it is incomparable with the E-2, it is better than nothing.

Da Mao improved on the basis of his own Ka-29, but instead of a big ball, it is a fly swatter, which hangs directly under the stomach and sticks out when needed.This early warning helicopter was named Ka-31.
Although the Ka-31 has been available since the Kuship test, the helicopter is easy to change, and the supporting radar is not so easy to get, so it has been done one after another until now, and it seems that it is still tossing.

In later generations, domestic aircraft carriers have two types of early warning aircraft, the Ka-31 imported at a huge cost, and the early warning aircraft built on the basis of Zhi-18. The latter uses an active phased array radar with more advanced performance. Therefore, After the Ka-31 was imported, it was in an idle state and was almost useless.Being criticized by many people, spending [-] million U.S. dollars, but it has never been deployed on an aircraft carrier, what a waste!
However, it is different now. If the Varyag is produced within a few years, the Zhi-18 early warning aircraft may not be so fast. That is to say, it is still necessary to get a few of this early warning helicopter back. .

If you want it to have the same performance as the E-2, it is impossible. After all, its airframe is limited. Take the Ka-31 early warning helicopter in front of you. Surveillance radar mainly detects altitudes below 801 meters, especially sea-skimming targets. For targets such as anti-ship missiles, the detection distance will not exceed 5000 kilometers.

In the final analysis, it is used to make up for the blindness, so as to save people from not knowing when the missiles fly to them.

However, since it was refitted from Ka-29, and Ka-29 was refitted from Ka-27, the sizes of the three are almost the same, which means that this early warning helicopter can not only board aircraft carriers, but also Equipped on ordinary destroyers, it can provide the fleet with the ability to supplement blindness at low altitudes at any time.

Even if the aircraft carrier does not need it, warships like the Hyundai class can still carry it.

Therefore, it is still necessary to introduce this kind of aircraft, and now, the Ka-31 is just around the corner!

"What is this plane doing? Is this asbestos-like thing installed below a phased array radar antenna?" Qin Tao began to ask the plane.

Asbestos tile?
Hearing Qin Tao's name, Zheng Ming almost burst out laughing.

Asbestos tile?The shape of that flat-panel radar antenna is really like an asbestos tile!
"Of course it's a phased array radar antenna." Hearing Qin Tao's words, a technician who was researching looked up and said, "This radar was developed by our Gorod Institute of Radio Science, and its performance is better than that of the British. Neptune Radar is much better."

This guy is engaged in radar ah!This sentence is so straightforward, in fact, even phased array radar is the most backward passive phased array radar.

Its antenna is nearly six meters long and one meter wide. It is divided into four rows, each row has 24 phase shifters, and there are only 96 in total. It is quite primitive and backward. In the 80s, it may be considered advanced, but now...

(Various materials have different opinions, some say pulse Doppler, some say phased array, personally feel that passive phased array is more likely.)
"Alexander, I think the shaking during the flight is caused by the rotation of the flat-panel antenna, and it has nothing to do with our aircraft." At this moment, the test pilot and the technician in flight suits continued to analyze the cause of the failure.

"No, our antenna won't have any problems. Its weight has been reduced to a minimum, only two hundred kilograms. It is impossible to make any changes to it. It can only be improved by your aircraft!" Alexander shook his head.

Although the Ka-31 has a weight of more than ten tons, there will still be big problems flying with a [-]-kilogram flat panel, especially since the flat panel has to rotate.

So now, they are still struggling with this issue.

Every test flight, once the antenna is deployed, the plane will shake back and forth, and there is a danger of crashing at any time!
Two hundred kilograms is indeed not heavy, but what would a six-square-meter signboard look like in a strong wind?

This problem has been bothering them all the time. After many days of research, it has not been resolved.

Hearing this, Qin Tao was overjoyed, this opportunity has come!
