Warship of Great Power

The combat forces are slowly changing. Once they find that the fighter plane is malfunctioning and cannot be saved, they will eject to escape without hesitation. After all, life comes first, and the fighter plane can still be produced. However, if it is discovered that the fighter plane may crash into the village, the pilot will still We will try our best to change the direction of the fighter plane, even if it delays the time of parachute escape. The lives of the villagers on the ground are also lives, and we cannot let the people on the ground be injured for our own reasons.

However, test flights are different.

The purpose of test flight is to find the defects of the aircraft. Various problems will be exposed during the test flight. If you parachute once you encounter danger, your life will be saved and the plane will crash. It will be difficult to find the cause of the fault. , the aircraft may not be finalized, and it may also threaten the lives of comrades.

Therefore, for test pilots, if there is a glimmer of hope, they will try their best, even if they miss the opportunity to skydive, even if they spill blood in the sky...

"How is our ejection device?" Qin Tao asked.

"Now, our ejection seat can completely guarantee zero-zero ejection." Mr. Lin has been participating in this project and is very familiar with all subsystems in the project: "In case of an accident, both pilots can eject upwards in the shortest time. , leaving the cockpit, there is a special reserved hatch above our cockpit."

It is easy for fighter pilots to say that once they need to eject, they can just get out of the transparent canopy. They can penetrate the canopy, throw it away, or release explosive cords. But what about bombers?

The old H-6 was famous for its difficulty in ejection. Many accidents occurred. Later, the improved H-6 focused on solving this problem. All four crew members sat on the nose of the aircraft, with the lid open above their heads. Once ejection was required, the four Each cover is opened in sequence, and the pilot ejects in sequence. The success rate of parachuting is greatly improved, similar to the Tu-22M.

Western bombers also have unique methods, such as the F-111, which uses the ejection method of the entire cockpit. When the pilot goes out, the entire cockpit can float on the water, and can be used as a temporary residence on land to wait for the arrival of rescuers. .

Our own H-20 has only two crew members. It is said that the F-111 method is more suitable. However, this method requires special research and development, and there is no reference object. What's more, there is only this type, and the later B2 was not used. Therefore, the technical staff did not adopt it, but used the previous method.

Although the appearance of the bomber is so smooth, if necessary, the covers on the top of the two pilots can be quickly opened, and then the ejection seats under the buttocks can quickly send the two pilots out, even during takeoff and landing. All can ensure safety.

Qin Tao nodded. Advanced ejection devices can save pilots' lives. This cannot be taken carelessly.

"President Qin, don't worry, we have confidence in our aircraft and there will be no chance of using the ejection seat." Lu Yong said.

"Of course, our aviation technology is quite strong. When you come back, I will have dinner with you." Qin Tao said.

The two walked to the nose landing gear, where a ramp had been extended.

The plane is so big that getting up and down is a troublesome thing. After all, it is not a bubble cockpit, so the cover cannot be opened from above. Moreover, it is too high and it is dangerous to climb the gangway. Therefore, designers have to rack their brains to find a way. Generally speaking, , it is a common operation on the nose landing gear. It is very close to the cockpit. As long as the upper and lower channels are designed, it will be fine. Moreover, there is no need for additional openings, which helps with stealth.

The two pilots got into the cockpit, put on their helmets, and made preparations for takeoff. When the goggles on the helmets were put down, graphics began to display on them. This helmet looked unremarkable, but in fact all the black technology was on the goggles. , this goggle can be used as a display screen!

What are the benefits of this? Of course it provides the same visual effect as during the day!

The H-20 bombers were dispatched at night. It was dark at night and nothing could be seen. It was a lot of pressure for the pilots. A common method is to wear night vision goggles. In the war in the early 1990s, almost every multinational force air force pilot in the air raid was one. However, this thing is uncomfortable to put on the head, and the field of view is not large enough, and the sight line is not far enough.

This bomber has an advanced infrared night vision device that can record everything in the outside world. However, if it is placed on the screen in front of the pilot, it is not intuitive enough. It is better to hit it on this piece of glass. Moreover, the pilot’s head Whichever way you turn, you will see the scene on that side. In this way, the night time will be the same as the day time.

In addition to displaying external scenes, various data can also be superimposed, such as navigation data, target data, etc. Therefore, this bomber does not have a heads-up display, only a large screen below.

Yes, the screen is huge.

How big is it? From left to right, a long bar! The length is nearly two meters and the height is fifty centimeters. None of the electric vehicles in later generations that have a display screen can match this display screen. It is just like a wide-screen movie. People who see this cockpit layout for the first time, Everyone will be amazed at the high-tech content of this device.

As for the test pilots, they joked more than once that they had to prepare a USB flash drive and copy a few movies in advance to get on the plane. They could just watch a few movies to relieve their boredom during the flight!

However, considering the issue of reliability, these are not a whole screen, but four screens spliced ​​together. Because the borders are very small, it is the same as not having any, and it will not affect the display between the seams at all.

At this time, various data are displayed on the screen, and the system is undergoing self-test.

The flying wing layout is difficult to operate and relies entirely on computers and a large number of sensors. If these sensors malfunction, it is likely to affect flight safety. The United States once lost a valuable B2 because several sensors were affected by moisture.

"This aircraft is too advanced to be displayed." Qin Tao sighed: "If it could be displayed, I would be very curious about the expressions of those people."

Mr. Lin smiled: "That's right, if we need to show off, that's when we show off our swords!"

The door of the hangar slowly opened, and everyone in the hangar strode out. Everyone was extremely excited. This brand-new aircraft will set a new record!

The original level of confidentiality here was very high, but now there are many more sentries, almost every three steps and one sentry, and every five steps and one sentry, not even a fly can fly over.

The runway has been inspected repeatedly, and the runway lights are on, just like beacons in the darkness.

Except for the runway lights, there was nothing else. The street lights in the entire factory were turned off. If you raised your head, you could see the stars in the sky.

The roar of the engine sounded. Hong Shiwen started the engine directly from the hangar and taxied directly over. The biggest advantage of this was to save time. After all, even at night, it was best to wait until the overhead satellite was gone. Although the satellite's sensor could see If not, try to keep it a secret.

The flying-wing bomber slid onto the end of the runway. In the dark night, it looked like a giant bat or a ghost.

Can you see the engine flames? Of course not!

A stealth aircraft must not only be invisible on radar, but also have infrared and visual stealth effects. If it carries two balls of fire on its butt when taking off like other aircraft, is it still a ghost in the night? That is the light in the dark night.

In order to achieve this effect, the H-20 has made a lot of innovative designs, such as the layout of the engine. Generally, fighter engines are arranged at the tail, while bombers can be arranged at the tail or under the wings, but the H-20 engine is Arranged in the center of the fuselage, the entire engine is buried inside the fuselage, and the air inlet is on the back of the fuselage. The airflow needs to be diverted to enter the engine. This will undoubtedly increase the air intake resistance and cause waste, but in this way It allows the engine to be completely covered inside the aircraft without exposing the blades, which is of great benefit to stealth. At the same time, part of the air coming in from the air inlet on the back of the aircraft enters the engine, and part of it goes directly to the channel below, bypassing the engine. Come to the rear of the engine.

The high-temperature and high-pressure gas from the engine is not sprayed directly to the outside. There is an S-curve here. Even the rear radar will never shine on the turbine blades of the engine. This stealth capability is omnidirectional. Neither the front nor the rear can illuminate the interior of the engine. At the same time, at the S-bend at the rear, part of the air sucked in from the front air intake will be released here, thereby cooling the exhaust temperature of the engine, and finally sprayed from the tail nozzle. When I went out, the temperature was not much higher than the surrounding temperature, thus achieving the purpose of infrared stealth.

There are also big flaws in doing this. For example, the thrust of the engine will be lost by more than 10%. For normal aircraft design, this solution is simply amateurish. However, for stealth bombers, this design is the most perfect. of.

The temperature of the exhaust gas is about the same as that of ordinary air, and nothing can be seen behind it. When it reaches the sky, the surrounding air is colder, and the exhaust gas from the tail nozzle will further cool down. You will definitely not be able to see any flames, even if it is right. When the tail nozzle is touched, no flame can be seen.

The most important thing for ordinary stealth aircraft is forward stealth capability. As long as it flies towards the opponent's radar without being discovered, because after flying past, the opponent's radar will definitely be gone and the threat will be solved. However, this kind of stealth During the mission, the bomber is not escorted by fighter jets. When it penetrates into the enemy's airspace, it must achieve omnidirectional stealth, so as to ensure that it can retreat after the attack is completed.

Bomber crew members have always been the most dangerous. During the brutal World War II, British and American bomber crews promised to go home after completing 25 missions, but in fact, their average life span was only 13 missions. .

Therefore, for bombers, protecting themselves is even more important than attacking the enemy. If the battle losses are too high, it means that the elite pilots will soon be exhausted, and they will become a group of rookies in the future.

The purpose of the stealth aircraft is to protect the pilot and allow the pilot to come back safely. This is the first goal, even exceeding the range, bomb load and other indicators.

The design of our aircraft is very good.

"How's it going? Our plane is pretty good, isn't it?" Mr. Lin said to him as if he knew what Qin Tao was thinking.

"Yes, it is indeed very good." Qin Tao nodded: "Our bomber will be a national treasure that protects the peace of our country."

Anti-ballistic missile technology is developing rapidly. In the future, the deterrence of ballistic missiles may decrease. However, this kind of strategic stealth bomber can fly to the target with nuclear bombs. There cannot be only one delivery tool, the more the better. The more, the safer.

"Start taxiing!" I don't know who shouted, and the runway suddenly became quiet. Everyone saw that Todoroki had just slid to the end of the runway, and after aligning with the center line of the runway, he started to accelerate!

The engine roared, and the black bomber began to accelerate. Its wide wings lifted lift in the air, growing more and more.

Normal aircraft have a wingspan smaller than the length of the fuselage, which means the aircraft looks longer. However, the wingspan of an aircraft with this kind of flying wing layout is greater than the length of the fuselage, making the aircraft look wider. At the same time, this It also gives the aircraft a very good lift-to-drag ratio. Simply put, this kind of aircraft will be easier to fly.

Although this bomber was very big, it only taxied a few hundred meters before the front landing gear left the ground. After another few dozen meters of taxiing, the rear landing gear also left the ground. Less than 500 meters away, it was like this. A strategic bomber took off. You know, a normal bomber can't fly even one or two kilometers.

This is the advantage of the flying wing layout. There is no waste in the entire aircraft, and all the shapes are used for flying. However, for a normal bomber, only the wings are used for flying, and the fuselage and tail cannot provide any help. Even the tail provides It's still negative lift, that is, it's the other way around.

Although this plane has already taken flight, no one takes it lightly. After all, this is a flying-wing layout!

The flying wing layout can provide lift for the entire fuselage, but at the same time, the maneuverability of this layout is very difficult. It is difficult to control without a fly-by-wire system. Therefore, many previous flying wing layout aircraft can only stay at prototypes or It is the design drawing stage. Even with fly-by-wire operation, if the flight control is defective, there will still be catastrophic consequences.

No matter how many times it is tried on the iron bird platform, it is still theoretical. What happens in practice depends on the first flight.

Watching the plane climb normally, the technicians felt uneasy.

Although the stealth aircraft is all black, it has navigation lights turned on to facilitate ground observation.

A light is installed on each of the three landing gears, forming a triangle in the air. By observing this triangle, you can know the flight status of the aircraft.

Very good, not bad. Keep it steady. After climbing to a few hundred meters, start turning!

Although the models of the aircraft are different, the process of the first flight is almost the same, taxiing, taking off, then turning, turning, turning again, and then appearing at the end of the runway, and then landing again, yes, it is around It’s just a round trip to the airport.

Now, the two originally symmetrical sides of the triangle began to have different lengths. This was because the bomber turned and the fuselage also tilted. Everyone held their breath. This simple turn was also a reflection of the A major test for flight control!

Finally, the two sides returned to the same length again, and the bomber had already flown in a direction parallel to the runway, just flying backwards. The big guy looked at the three lights with expectation in his eyes.

The side length changed again, the bomber continued to turn, finally aligned with the runway, and began to land!

"Quick, get the flowers ready!" Mr. Lin shouted excitedly.

As long as it lands, the first flight will be considered a successful completion, and the next step will be flowers and applause.

"It's ready, over there in the hangar."

The main landing gear of the bomber lightly touched the ground and landed steadily, followed by the main wheels in front, and then began to taxi on the runway. After more than a thousand meters, it slowed down to almost a stop, and then began to slide. Toward the hangar.

There is a huge contrast between takeoff and landing.

"We can't use a drag parachute or a reverse thrust device. We all rely on braking. The distance of a thousand meters is not that long." Pleshakov said.

Normal fighter jets rely on parachutes to slow down, and normal passenger planes rely on the reverse thrust device on the engine to slow down, but what does this stealth bomber rely on? With nothing but braking, this distance was pretty good.

"Yes." Qin Tao nodded: "Even if it stops at a distance of two thousand meters, it is still very good. The performance of our aircraft brake pads is very good."

At that time, we were surprised to see the Mirage 2000 brake directly. But now, we also have first-class brake pads, which can be used not only on fighter jets, but also on bombers!

"That's natural. It uses the same friction plate as the lift fan clutch of vertical take-off and landing fighter jets."

The big guy said and started walking towards the hangar. Some people disliked the slow pace, so walking turned into running.

Mr. Lin also has long strides and fast steps, just like the young man.

By the time they entered the hangar, there were already bursts of applause.

"These two guys didn't wait for me!" Mr. Lin complained while continuing to quicken his pace.

Lu Yong and Wen Ping had already walked down and looked at the crowd below. They tried hard to find the shadow of Mr. Lin. At this time, what they wanted most was to report to the old leader.

However, before he could see it, he was already lifted up by the lively people and thrown high into the sky.

Looking at the lively scene inside, Mr. Lin also smiled.

"Hey, be careful, don't throw it up and fail to catch it!"

Qin Tao walked over and looked at the skin on the leading edge of one wing. Our bomber shouldn't be that delicate, right?

"We have specially developed a new coating for this kind of bomber. It not only has better stealth effect, but also has good maintainability. It is impossible to need maintenance after flying once." Pleshakov followed him, as if She knew what he was worried about and opened her mouth to explain.

"Yes, if you have to maintain it once every time you fly, then it's okay." A technician on the side took over the conversation.
