Chapter 932 The Stealth Bomber That Achieved Alien Technology
Compared with the previous H-[-], this bomber is bigger and more modern.

Qin Tao and the others saw the cabin section of the cockpit. There were two openings on both sides of the cabin section. From the openings, workers could be seen busy installing various equipment. The advanced LCD screen was already plugged. Inside, it looks modern.

"The biggest advantage of this bomber is that it greatly improves the reliability of ejection and rescue operations." Mr. Lin pointed to the cockpit with satisfaction: "The HTY-8 ejection seat is installed inside. Once there is a risk, it can guarantee the safety of the four crew members inside. All members will survive.”

In the old H-[-], the crew members were located all over the aircraft, ejecting upwards and ejecting downwards. Once an accident occurred, it was difficult to ensure that everyone could be saved by ejection, and it might even lead to the destruction of the entire aircraft.

Now, this new bomber has avoided this problem. The four crew members sit together in two rows, with the captain and pilot in front, the weapons operator and navigator behind, and above everyone's head. Hatch cover, when you need to save someone, just eject directly from the top of the head, and the chance of survival will be greatly improved.

Moreover, the famous HTY-8 ejection seat is used.

"Have we copied the K-36D?" Qin Tao asked excitedly.

When the Su-27 fighter technology was first introduced, the old man also played a lot of tricks. The aircraft technology can be given, but the engine will not be given anything. When asked, this is a third-party patent, and the same is true for the ejection seat. That's a way to get stuck in the neck of Vostok's production.

But now, this hope has been shattered. Dongfang has a mature turbofan 36. At the same time, Dongfang also has an ejection seat imitating K-8D. According to the serial number of domestic products, it is named HTY-[-].
"Yes, we not only imitated it, but also improved it with our own technology. However, when it comes to the ejection seat, our HTY-5 is actually pretty good. Lao Maozi's ejection seat is still ejected with a throw cover. We My own HTY-5 already has micro-explosion cover penetration technology." Mr. Lin continued: "It's just that our ejection seat was developed for the J-[-], and it is mainly used on domestic aircraft, and it does not match Lao Maozi's aircraft. That's why it wasn't equipped."

The country also has its own ejection seat, and the HTY-5 is one of the best. This ejection seat adopts the world's advanced technology. In order to allow the pilot to fly out faster, a detonating cord was buried in the center of the hatch cover, causing the hatch cover to burst directly. Although this kind of seat was numbered 22, it was only because the project was established earlier. Speaking of performance, It is much more advanced than the later HTY-5 and HTY-6.

Lao Maozi's cockpit has its own characteristics, and it is more suitable to match their ejection seat. Therefore, HTY-8 is also used in many places. The domestically produced Su-27 series models: J-8, J-8, J-[-] Sixteen, these all use HTY-[-]. At the same time, this bomber also uses HTY-[-].
The emergence of this kind of ejection seat makes it easier for the pilot to eject and save life. As long as the pilot does not delay the timing of parachuting to save the life of the aircraft or the lives of ordinary people on the ground, he can still escape safely.

Qin Tao looked at the inside of the bomber being assembled and was very satisfied: "It seems that our modern electronic equipment has been used to improve this bomber."

"Of course." Zhou Guozhen introduced at the side: "We have installed the most advanced electronic equipment, such as the naval H-1.5J. We used a [-]-meter-diameter radar antenna to give it a range of [-] kilometers. The aircraft carrier formation can be found within the sea search distance and provide guidance for the supersonic long-range anti-ship missiles mounted under the wings."

The AWG-9 radar achieves a search distance of up to 910 kilometers by relying on the 320 mm caliber radar antenna. This bomber has a larger nose space, which also means that a larger caliber radar antenna can be installed. This radar has already It is not an ordinary airborne radar, but it is similar to the Soshui-2000MS radar used by the Yun-[-] J airborne warning aircraft, with a longer search distance and more advanced performance.

At this time, after hearing Zhou Guozhen's words, Qin Tao nodded with satisfaction: "Yes, if our navy's bombers can find and attack targets on their own, it will greatly improve the flexibility of executing missions. However, if our bombers can mount Eagle If you hit -21, that would be even better."

"The YJ-21 is a ballistic missile!" Wu Shengli frowned, and then reacted: "You mean, we want to develop an air-launched anti-ship ballistic missile?"

"Yes, we have such a good weapon launch platform, of course we must use it. Anti-ship ballistic missiles are our big killers. The combination of H-21J and Eagle-[-] will definitely make the enemy scared. arms."

"President Qin, you have been planning for the navy, and you are also planning for our air force." Elder Lin was not happy there.

"The Navy has air-launched anti-ship ballistic missiles, and the Air Force can also have them." Qin Tao said: "The Navy's is to attack moving targets at sea, while the Air Force's is to attack fixed targets on land. It will be easier in comparison. You need ballistic missiles can also be improved from the YJ-21, just change the warhead. Although this project is funded by the Navy, if the Air Force needs it, the Navy will never be stingy. Dad, I said it is that OK?"

Wu Shengli was stunned for a moment, then realized what he was doing, nodded and said, "Yes, our Navy is very impressive, but unlike some guys in the Air Force, even the equipment of three melons and two dates has to be carefully compared with our Navy."

Mr. Lin also reacted: "Can the investment in ballistic missiles and bombers be the same? What three melons and two dates? I will trade my house in the capital for your house in Mingzhou. Are you willing?"

"I don't have a house in Mingzhou." Wu Shengli answered simply.

Everyone continued to move forward while talking.

After the nose structural parts, there is the fuselage, which is divided into many components, which are assembled separately and then docked together. This can speed up the assembly efficiency. The two shiny titanium alloy wing boxes in the front look so dazzling.

For a variable-sweep wing bomber, the wing box is the most important component. Whether it can be processed also determines whether the aircraft can be produced.

"The titanium alloy wing box is provided by the Mingzhou Group. The titanium alloy 3D printing technology is fast, efficient and of good quality." Zhou Guozhen said with emotion: "The Mingzhou Group is everywhere in the R&D and production of our bomber. .”

"Needless to say this bomber, ours..." Mr. Lin looked at the workers around him, but he still gave up. There are many things that cannot be said nonsense. These workers outside are not qualified to know the research and development of the bomber in the deepest part of their workshop. project.

At this time, everyone had reached the tail structure section of the aircraft. Qin Tao looked at the layout of the tail: "We still retain the tail cannon?"

The old H-[-] has a tail cannon, and it even requires a special gunner to be in position at the tail, ready to fire at any time. The tactics used during World War II have no meaning now. The way to deal with bombers is no longer to bite the tail of the enemy plane and then use it. The cannon fired, but it was the missile launched by the enemy plane. It is said that this kind of tail gun has no significance in existence.

"That's right, it's better to have something than nothing. Although there won't be enemy planes biting their tails to chase after them, there will still be missiles flying over. After we have optimized the program, this tail gun has a certain chance of being able to intercept air-to-air missiles." Missiles, so that the safety of the aircraft can be better protected."

Intercept missiles?

Qin Tao looked at the dual-mounted 23mm cannon at the back and wondered if it would be more effective to replace it with 730, but if the weight is too large, it is obviously inappropriate.

The next plane that was being assembled appeared in front of everyone, and the huge NK-32 engine was being installed. Looking at this engine, everyone was filled with emotion.

An advanced fighter must have an advanced engine. This bomber can be quickly finalized and put into production, which has a lot to do with the successful imitation of the NK-32 engine.

"Mr. Qin, this engine is also thanks to your help."

"This is the credit of the 430 Factory." Qin Tao said: "They originally said they would develop a gas turbine based on this engine, but I don't know what happened later."

Factory 430 first proposed the research and development plan for the 32-megawatt gas turbine at the beginning, which was an improvement on the basis of NK-430.Qin Tao said that the market is competitive, as long as they also work hard, they can compete.

"They abandoned this project. At present, our air force and navy need a large number of new H-[-]s. This kind of engine is also in short supply. The first batch of H-[-] K and H-[-] J in the army have been flying too frequently. It's time to change the engine. They only produce engines for bombers, and they are too busy." Zhou Guozhen said.

"Has it reached the end of its lifespan? How long is the lifespan of this engine?" Qin Tao opened his eyes wide. Could it be the same as the previous engine, which only has three hundred hours?
"Currently, the service life before overhaul is 430 hours. Factory [-] is actively working hard to increase the overhaul interval of this engine to [-] hours." Zhou Guozhen introduced.

No wonder!
The engine life before overhaul is only [-] hours, which is simply not enough!This kind of bomber is a long-range bomber. It may fly for more than ten hours to perform a mission. If it flies three times a month, it will be fifty or sixty hours. It will reach the end of its life in ten months, which is about one year. The navy and air force I can't stand it.

The previous engines had a short lifespan, but the price was also cheap, so you wouldn’t feel bad if you threw them away. Now that the engine lifespan is too short, the navy and air force are really struggling. If you add in the fact that a large number of pilots must be trained to prepare for war, then overhaul The interval is even shorter.

"One thousand hours is not enough, it is better to overhaul once every fifteen hundred hours." Wu Shengli said: "However, we can't force it too much. After all, this is a high-thrust engine. It is good to give priority to ensuring that the thrust meets the standard. In other words, We've come to an end, shouldn't it be time to check out your projects?"

It only took two hours to walk this way. What’s next?
"I'm hungry. I have to go eat first. Lao Wu, where's the wine you brought?" Lao Lin said, touching his stomach.

"No, absolutely not!" Wu Shengli refused immediately: "Old Lin, what idea did you have, do you think I don't know? You deliberately delayed here, and when it was time to see your project, you went to eat. There was so much time for eating. Drink a few cups, and then we can’t wake up, we can’t watch it! Let me tell you, if you don’t see your project, you have no way to drink my Moutai!”

"Anyway, I'm hungry and dizzy, you can figure it out!"

"Taozi, where are the compressed biscuits you brought? Give him some."

Qin Tao could only take out the compressed biscuits from his pocket.

Lin Laobai glanced at Qin Tao: "This thing is not very interesting. Okay, I will take you to see it. It will take up to half an hour. After half an hour, we will go to eat!"

After passing through the factory building here, after exiting, they entered another factory building that was guarded at all levels. When they opened the door of the workshop, everyone took a deep breath.Isn’t this too science fiction?
A bomber with flying wings appeared in front of their eyes.

Like the B2 bomber, the bomber in front of you has no traditional fuselage and wings. The entire aircraft looks like a flying wing structure.

In the center is the bulging fuselage. You can see the porthole glass in the front. There are air intakes on both sides of the fuselage. Above the fuselage, nothing can be seen below. From the nose to both sides, there are two diagonal lines. Extended to form the wings on both sides, the entire nose is like a spear.

At this time, what they saw was the nose part of the aircraft. Just seeing this part made them extremely shocked.

We finally have alien technology too!
The B-2 bomber is like a ghost. It can appear in any corner of the world at any time, making it difficult to guard against. Moreover, this bomber can also carry a large number of bombs, which is unmatched by tactical attack aircraft such as the F-117. .

Although Dongfang has H-[-]K and H-[-]J, these bombers have no stealth ability after all, and they will be spotted from a distance. When attacking, they can only use the advantage of distance. Four to five hundred kilometers away, the opponent Launch long-range missiles before interception begins, and then return. As for flying over the opponent to carry out carpet bombing?There is no such ability at all.

Only stealth machines will do, and stealth machines will have a greater deterrent effect on the enemy.

Now, the East finally has a stealth bomber!
Countless engineers were busy beside the plane, and when they saw Qin Tao and his party approaching, some of them shouted excitedly.

"President Qin!"

"President Qin!"

Another one strode over directly from the three-story iron frame. His tall nose and beard that had no time to shave all showed his identity.

"Mr. Qin, you are finally here! Our second stealth machine project is already in the prototype manufacturing stage!" Mao Duozhang excitedly said to Qin Tao.

"Well, you have worked hard."

"When I came to the East, I originally thought I could only build one project. In fact, for me, the success of the stealth fighter project has given me no regrets. And now, the stealth bomber project makes me feel that my life It makes sense!"

When he was in the Yakovlev Design Bureau, he was so depressed and helpless. When he came to the East, his life was rejuvenated and he started a new journey!

He never dreamed before that he would actually be able to participate in this kind of project, but now, he not only participated, but also the main person in charge of it, and he led the entire invisible appearance.

"It would be great if you can find the meaning of life." Qin Tao said, "Mao Duanzhang, how about introducing this plane to us?"

"Okay, our aircraft has a flying wing layout, which is rare among aircraft models in the world. Moreover, in order to reduce the radar reflection area, our bomber does not have a vertical tail. It also relies on the rudder surface at the tail. To deflect, this requires superb flight control technology, but the flight control is not our responsibility, it is developed by related brother units, we only care about the body, and it is enough to have the best stealth shape. The whole nose is similar to B2, but the tail is It's different."

Now Mr. Lin became a spectator, and everyone was listening to Mao's fragmentary introduction.

"The tail of the B2 bomber uses a complex folded line, which is equivalent to combining two Ws. We use a simple folded line with only one W." Mao Duanzhang pointed to the tail for everyone, which is still under construction. The shelf, you can see the basic structure of the tail.

"Not bad, you are creative." Qin Tao nodded with satisfaction. The Americans also simplified the tail design when they developed to the B21. Our side directly used a similar design to the B21, which looks much more pleasing to the eye.

"Did you create the entire appearance?" Wu Shengli was very excited.

"Yes, we developed it, but brother units are also developing carrier-based drones and plan to use this structure."

There was excitement on Wu Shengli's face, okay, our navy can also use this kind of thing, and your air force should take care of yourself, and we don't have to buy it at that time, just use this kind of drone directly, it will be taller.

"The air nozzle at the tail has not been installed yet, and there are complicated pipes inside. Although this reduces the flow rate of the airflow from the tail nozzle and the thrust, it improves the stealth. The exhaust gas it emits cannot be higher than the temperature of the atmosphere How many."

Stealth aircraft not only need radar stealth, but also infrared stealth, so its engine layout is also very particular.

When the domestic J-[-] was being manufactured, a cover was added to the rear of the engine. This was a structure inherited from the J-[-]. It seemed logical at first. Later, under the guidance of designer Lao Maozi, the cover was removed. Suddenly, I was surprised. Discovery: The thrust increased by [-]%!
Now we go in the opposite direction and put the engine into the cover. There are complex pipes inside. Cold air is sucked in from the outside to cool the nozzle. This will of course lead to a reduction in the thrust of the engine, but everything is aimed at low detectability. , the thrust reduction is acceptable.

The top has not been covered yet, so you can see the complicated jet pipeline, which makes everyone click their tongues.

"This kind of engine layout is inconvenient to disassemble and assemble!" Wu Shengli suddenly thought of something: "Let's look at those planes outside. The overhaul life is only [-] hours, and the engine has to be dismantled once a year. Now put the engine here. Frequent disassembly and assembly will not only be very cumbersome, but also destroy the stealth appearance?"

The technology of a stealth bomber is very complex. Taking into account the stealth requirements, the arrangement of the engine in this way will also lead to many other problems.

Conventional engines are disassembled from below. With just an iron frame, a few technicians can dismantle the engine. But for the bomber in front of you, you have to do it from above, that is, you have to disassemble the upper skin and then remove the engine. Hoist it up.

Moreover, there are still four engines, so the workload is not small for one maintenance.

After hearing his words, Mao spread his hands in disarray: "This has nothing to do with us. We are not responsible for the engine. We do not have advanced long-life engines. It is not something we can decide."

The short life of the engine has nothing to do with the complete machine designer. We are only responsible for the overall consideration.

"The test flight takes a long time. After the test flight is successfully finalized, it is estimated that our engine overhaul life can be increased to one thousand hours." Mr. Lin said: "Even if it is a [-]-hour overhaul, we have to accept it."

"Yes, Mr. Lin is right. This kind of strategic bomber needs to be cared for as carefully as a child." Qin Tao said: "I wonder how our stealth paint is developed? You don't need to re-spray it every time you fly. ? You don’t need to put it in a special constant temperature and humidity hangar, right?"

"And such delicate paint?" Everyone opened their eyes wide.

Stealth bombers are very delicate. Look at the Yankee B2 bomber. In the more than ten years since it was finalized and equipped for the army, the ground crew at the base could not solve the coating maintenance problem of the stealth aircraft. The coating of this aircraft is very special. The hangar must have air conditioning, constant temperature and humidity. Only under certain conditions can the integrity of the coating be ensured. And the key is that after each flight, the coating will be damaged and then re-sprayed. The ground crew cannot dry it. I need technicians from the factory to help.

The B2 was discontinued after only about twenty were produced. On the one hand, the Red Empire is gone and there is no need for so many. On the other hand, it is naturally because the maintenance of this bomber is too complicated. If it purchases hundreds of them, the U.S. Air Force will So exhausted.

"It seems ours is not, that's good." Qin Tao nodded.

"In order to pursue stealth, we use composite materials on a large area of ​​the fuselage, but the specific effect is not clear. If there are cracks and the like after the test flight, I am afraid that we will have to rework." Mao Duanzhang said.

The use of composite materials on the fuselage can not only reduce weight, but also improve stealth. After all, metals have the strongest ability to reflect electromagnetic waves, and composite materials rarely reflect.However, this is the first time that composite materials have been used in a large area, and no one knows what will happen.

"It doesn't matter. If there is an accident, we can continue to conduct research and develop more advanced composite materials. When the research and development are mature, they can also be used in our navy's drones." Wu Shengli comforted.

Mr. Lin gave him a white look: "If your navy doesn't provide research and development funds, you can make sarcastic remarks here!"

"How about the avionics system?" Qin Tao quickly changed the subject.
