Compared with the previous H-6, this bomber is larger and more modern.
The cabin section of the cockpit appeared in front of Qin Tao and others. There were two openings on both sides of the cabin. From the openings, workers could be seen busy inside, installing various equipment, and advanced LCD screens had been plugged in.
Entering, 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, which can ensure the four crew members inside if there is a risk.
All members will survive."
In the old H-6, 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 total destruction of the aircraft and the death of everyone.
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 rescue someone, just eject directly from the top of the head, and the chance of survival will be greatly improved.
Moreover, it uses the famous HTY-8 ejection seat.
"Have we copied the K-36D?" Qin Tao asked excitedly.
When the Su-27 fighter technology was introduced, Lao Maozi also played a lot of tricks. The aircraft technology could be provided, but the engine would not be provided. When asked, this is a third-party patent, and the same is true for the ejection seat. Trying to use this
A way to jam the neck of Vostok fighter production.
But now, this hope has been dashed. Dongfang has a mature turbofan X. At the same time, Dongfang also has an ejection seat imitating the K-36D, which is named HTY-8 according to the domestic product serial number.
"Yes, we not only copied it, but also used our own technology to improve it. However, when it comes to the ejection seat, our HTY-5 is actually not bad. Lao Maozi's ejection seat is still a cover ejection. We
My own HTY-5 already uses micro-explosion cover penetration technology." Mr. Lin continued: "It's just that our ejection seat was developed for the J-10. It is mainly used on domestic aircraft and does not match Lao Maozi's aircraft.
That’s why I didn’t have the equipment to go up there.”
Domestic countries also have their own ejection seats, and HTY-5 is one of the best. This ejection seat adopts the world's advanced technology. For example, in order to adapt to the high overload cockpit of the J-10, the seat's recline angle reaches 22 degrees. For example,
In order to allow the pilot to fly out faster, a detonating cord was buried in the center of the hatch, causing the hatch to rupture directly. Although this kind of seat received the number 5, it was just because the project was established early. Speaking of performance,
It is much more advanced than the subsequent HTY-6 and HTY-7.
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-11, J-15, J-15
Sixteen, these all use HTY-8. At the same time, this bomber also uses HTY-8.
The emergence of this kind of ejection seat makes it easier for pilots to eject and save lives. As long as the pilot does not delay the opportunity to parachute to save the lives of the aircraft or 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 also 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-6J. We used a 1.5-meter-diameter radar antenna to give it a range of 500 kilometers.
The search distance at sea can completely find the aircraft carrier formation and provide guidance for the supersonic long-range anti-ship missiles mounted under the wings."
The AWG-9 radar relies on a 910 mm diameter radar antenna to achieve a search distance of up to 320 kilometers. This bomber has a larger nose space, which also means that a larger diameter radar antenna can be installed. This kind of radar has already
It is no longer an ordinary airborne radar, but similar to the Shuishui-2000MS radar used by the Y8J air surveillance aircraft, with a longer search range 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 targets and attack by themselves, the flexibility of performing missions can be greatly improved. 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 weapons launch platform, of course we must use it. Anti-ship ballistic missiles are our big killer. The combination of H-6J and YJ-21 will definitely make the enemy frightened.
arms."
"President Qin, you have been planning for the navy and also for our air force." Mr. Lin was unhappy 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
The ballistic missile 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 are you talking about? I will trade my house in the capital for your house in Mingzhou, are you willing?"
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "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 butted 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 Mingzhou Group. Titanium alloy 3D printing technology is fast, efficient and of good quality." Zhou Guozhen said with emotion: "Mingzhou Group is involved in the research and development and production of our bomber.
.”
"Needless to say, this bomber, ours..." Mr. Lin looked at the workers around him, but gave up. There are many things that cannot be said carelessly. The 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-6 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 not to bite the tail of the enemy plane and then use it.
The cannon fired, but the enemy aircraft fired missiles. It is said that this kind of tail cannon has no meaning in existence.
"That's right, something is better than nothing. Although there won't be enemy planes biting the tail to pursue, there will still be missiles flying over. After we have gone through the optimization process, this kind of tail cannon has a certain probability of intercepting air-to-air missiles.
missiles, so that the safety of the aircraft can be better protected."
Intercepting missiles?
Qin Tao looked at the twin 23mm cannons at the back and wondered if it would be more effective to replace them with the 730, but if they were too heavy, they would obviously be inappropriate.
An aircraft that was undergoing final assembly appeared in front of everyone. The huge NK-32 engine was being installed. Looking at this engine, everyone was filled with emotion.
An advanced fighter aircraft must have an advanced engine. The fact that this type of bomber can be quickly finalized and put into production 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."
The original research and development plan for the 40-megawatt gas turbine was first proposed by 430 Factory, which was an improvement on the NK-32. Later Tianjiao Aviation came up with it, and 430 Factory expressed dissatisfaction for a while. Qin Tao said that there is market competition.
, as long as they also figure it out, they can compete.
"They gave up on this project. Currently, both our Air Force and Navy need a large number of new H-6 engines. This kind of engine is also in short supply. The first batch of H-6K and H-6J in the army have flown too frequently, and it is time to replace the engines.
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?
"The current life before overhaul is 500 hours. The 430 Factory is actively working hard to increase the overhaul interval of this engine to 1,000 hours." Zhou Guozhen introduced.
No wonder!
The lifespan of the engine before overhaul is only 500 hours, which is simply not enough! This kind of bomber is a long-range bomber, and it may take more than ten hours to fly a mission. If you fly three times a month, you will have 50 or 60 hours, ten hours.
The life span will be over in a few months, that is, about a year, and even the navy and air force cannot bear it.
In the past, the engine life was short, but the price was also cheap, so it didn’t hurt to throw it away. Now the engine life is too short, so the navy and air force are really struggling. If you add 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 would be best to overhaul it once every 1,500 hours." Wu Shengli said: "However, we can't be too demanding. After all, this is a high-thrust engine. It would be good to give priority to ensuring that the thrust reaches the standard. In other words,
We have come to the end, is it time to take a look at your project?"
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 are deliberately delaying here, and when it's time to see your project, you go to eat. You have a lot of time to eat.
If you drink a few drinks and then you can’t wake up, we won’t be able to watch it! Let me tell you, if you don’t see your project, there’s no way you can drink my Moutai!”
"Anyway, I'm hungry and dizzy. You can do whatever you want!"
"Taozi, where are the compressed biscuits you brought? Give him a few."
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 flying-wing bomber appeared in front of them.
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.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! At this time, what they saw was the nose part of the aircraft. Just seeing this 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 the H-6K and H-6J, these bombers do not have stealth capabilities after all. They will be spotted from a distance. When attacking, they can only use the distance advantage. The opponent is four to five hundred kilometers away.
Launching long-range missiles before interception has begun, and then returning home. As for flying over the opponent to carry out carpet bombing? There is no such thing as that.
Only stealth aircraft will do, as stealth aircraft will have a greater deterrent effect on the enemy.
Now, the East finally has a stealth bomber!
Countless engineers were busy beside the plane. When they saw Qin Tao and his party coming, some of them shouted excitedly.
"Mr. Qin!"
"Mr. 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 aircraft project is already in the prototype manufacturing stage!" Mao Duanzhang said to Qin Tao excitedly.
"Well, thank you for your hard work."
"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 could actually participate in such a project, but now, he not only participated, but was also the main person in charge of it. He was in charge of the entire stealth appearance.
"It would be great if you can find the meaning of life." Qin Tao said: "Mao Duanzhang, how about introducing us to this plane?"
"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, and it also relies on the tail rudder.
To deflect, this requires superb flight control technology, but the flight control is not our responsibility, it is developed by relevant brother units. We only care about the body of the aircraft, as long as it has the best stealth shape. The entire nose is similar to the B2, but the tail is
It’s different.”
Now Mr. Lin also became a spectator, and everyone was listening to Mao's fragmentary introduction.
"The tail of the B2 bomber uses a complex polyline, which is equivalent to two W's combined. We use a simple polyline, with only one W." Mao pointed to the tail in a broken chapter, which is still under construction. Through the iron
On 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. We 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. Your air force can just take care of it. We may not necessarily purchase it when the time comes. We can just use drones with this shape. It will be more advanced.
"The jet nozzle at the tail has not been installed yet, and there are complicated pipes inside. Although this reduces the airflow speed from the tail nozzle and reduces the thrust, it improves the stealth. The exhaust gas it sprays is no higher than the temperature of the atmosphere.
How many."
A stealth aircraft not only needs radar stealth, but also infrared stealth, so its engine layout is also very particular.
When the domestic J-8 was being manufactured, a cover was added to the rear of the engine. This was a structure inherited from the J-7. It seemed logical at first. Later, under the guidance of designer Lao Maozi, the cover was removed, and suddenly I was surprised.
Found: Thrust increased by 3%!
Now we go in the opposite direction and put the engine into the cover. There are complicated 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 reduction in thrust is acceptable.
The top is not covered yet, so you can see the complicated jet duct, which makes everyone smack their lips.
"This kind of engine layout is not convenient for disassembly and assembly!" Wu Shengli suddenly thought of something: "We looked at those aircraft outside. The overhaul life is only 500 hours, and the engine has to be disassembled once a year. Now the engine is arranged here.
Frequent disassembly and assembly will not only be cumbersome, but also destroy the stealth appearance, right?"
The technology of a stealth bomber is very complex. Considering the stealth requirements, the engine layout 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.
And there are still four engines, so the workload is quite a lot of 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 overall engine 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 500-hour overhaul, we have to accept it."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Yes, Mr. Lin is right, this kind of strategic bomber needs to be cared for like a child." Qin Tao said: "I don't know.
How is our stealth coating developed? It doesn’t need to be re-painted after every flight, right? Doesn’t it need to be placed in a special constant temperature and humidity hangar?”
"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 base ground staff could not solve the coating maintenance problem of the stealth aircraft. The coating of this kind of 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 guaranteed. And the key is that after every flight, the coating will be damaged and then re-sprayed. The ground crew cannot dry it.
We need technical personnel 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 hundreds of them are purchased, the U.S. Air Force
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 cracks or other conditions are found after the test flight, I am afraid it will have to be reworked." Mao Duanzhang said.
The use of composite materials on the fuselage can not only reduce the weight, but also improve the stealth. After all, metal has the strongest ability to reflect electromagnetic waves, and composite materials rarely reflect. However, this is the first time that composite materials are used on a large area. There will be problems.
No one knows what the problem is.
"It doesn't matter. If an accident occurs, we can continue to research and develop more advanced composite materials. When the research and development is mature, it can also be used on our navy's drones." Wu Shengli comforted at the side.
Mr. Lin gave him a white look: "Your navy doesn't have R&D funds, so you can make sarcastic remarks here!"
"How is the avionics system?" Qin Tao quickly changed the subject.
