As everyone knows, because of the harsh international environment at that time, our country was facing the threat of nuclear war, so our country had to ignore the immaturity of technology and had to forcibly mount nuclear submarines. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Doing so not only caused a lot of waste, but also left a lot of trouble.

Among them, loud noise is a sequelae.

The United States laughs at the fact that our country's submarines are not good, they are too noisy and can be detected from afar. Western countries, led by the United States, have always talked about things, and whenever they have the opportunity to slander us, they will talk about how loud the noise is.

It was not until a US naval exercise that our country's submarine collided with US sonar, and the United States had to change its tune and say that it would develop a new type of sonar.

Before this collision, the United States also started its propaganda machine, describing the noise of our country's submarines as if it were tractors, as if it could be detected without sonar.

This collision made the United States lose face and became a big joke.

With the technological progress of our country, the noise of our country's submarines is getting lower and lower, and it is difficult to detect. However, as long as the noise is greater than the background noise of the ocean, it is possible to be detected.

Therefore, the noise of submarines has always been aimed at no more than 90 decibels of background noise in the ocean, and all countries are working hard to achieve it.

Once the noise does not exceed 90 decibels, it will be completely masked by the background noise of the ocean, and it will become a real "oceanic black hole" that can no longer be found.

However, it is too difficult to achieve this. The propeller is the source of power for the submarine, and it is precisely the main source of noise, which becomes a contradiction.

If there were a new way to power the propellers, the noise would be much lower, and it would not be impossible to fall below the background noise of the ocean.

The submarine shown in this video is one such submarine, not only because it has no propellers, but it is also so fast that it can run faster than a car, which is amazing.

As we all know, the speed of submarines has always been very slow, and even when the navy conducts military parades, it has to put submarines in the front, because if they are placed in the back, they will fall behind because they are not fast.

Fast speed means that you can reach the launch site faster, which is in line with what our ancestors said.

And, it's much safer. It is known that against submarines is torpedoes, and anti-submarine torpedoes are not very fast. The existing anti-submarine torpedoes will not be able to catch up at all in the face of such submarines, and there will be no talk of fighting anything.

Another aspect of security is that even if you are unlucky enough to be discovered by an anti-submarine aircraft, you can quickly maneuver and get rid of the enemy.

In a word, such a submarine is too tempting.

As a military fan, Ye Chen can't wait to master this technique immediately.

Just when Ye Chen was drooling, this video was played, followed by surface ships.

"What a big army...... Hang Mom. All kinds of surface ships amazed Ye Chen. What shocked Ye Chen the most was the video of the aircraft carrier.

This aircraft carrier is much larger than the current U.S. Fart Mitz-class aircraft carrier, two or three times larger, not to mention 300,000 tons, it is not far behind.

It's amazing to have such a big hangma. The Nimitz-class aircraft carrier of the United States is the aircraft carrier with the strongest comprehensive combat capability at present, and it can only kneel when encountering this kind of aircraft carrier.

"That's a lot of speed." Ye Chen was shocked to find that the speed of this aircraft carrier was so fast, and the speed would not be lower than two hundred kilometers per hour.

The speed of the Nimitz-class aircraft carrier of the United States is 30 knots per hour, that is, 54 kilometers per hour.

"There are no propellers." Ye Chen was shocked to find that this kind of aircraft carrier does not have propellers, just like submarines, and is equipped with thrusters behind the buttocks.

With a size of nearly 300,000 tons and a speed of no less than 200 kilometers, such an aircraft carrier is absolutely invincible. If our country has such an aircraft carrier, needless to say, the United States will definitely not dare to make trouble around our country, and it will roll as far as it goes.

If the United States dares to stir up trouble around our country, our country can send such an aircraft carrier to the United States to visit the United States and see if the United States is afraid?

"I'm going to decide. If you don't say it, change the ship technology. Ye Chen immediately changed his mind, and he had to exchange this technique for him.

"Uncle, you play with me! Thief God! The next moment, Ye Chen's eyes were about to fall off, staring at the contribution value needed for the ship's technology.

20 million!

Twenty million contribution points, this is the most expensive technology Ye Chen has discovered so far.

Ye Chen has been busy for so long, and the total contribution value he has obtained is no more than that.

If he had appeared earlier, Ye Chen might have saved up contribution points and used them to exchange for ship technology.

Ye Chen was very depressed, crying with a sad face, your uncle, you actually let me see that I can't change it, isn't this playing with people?

In desperation, Ye Chen had no choice but to exchange for the primary aircraft technique.

The familiar brilliance entered from the center of the eyebrows, and the mind was full of swelling. I don't know how long it has been, maybe it's a moment, maybe it's a long time. Until everything returned to normal, Ye Chen had already mastered the primary flying machine technique.

Ye Chen took a closer look and became happy again, although he didn't get the ship technology, but the aircraft technology was not bad, and it happened to be what our country urgently needed.

The technical content of primary aircraft is extremely wide, including helicopters, airplanes, unmanned aerial vehicles, aerospace aircraft, and high-speed aircraft. There are all kinds of flying machines that have already appeared, are being researched and designed, and are in concept.

Because of the limited financial, manpower, and material resources at the beginning of the founding of the People's Republic of China, our country could only choose one priority for development in aviation and aerospace. In view of the fact that aerospace was more applicable to the situation of our country at that time, the country chose to give priority to the development of astronautics. As for aviation, it was not given up either, only limited funds were allocated, which seriously limited the development of aviation in our country.

The education we received since childhood, the "two bombs and one satellite" are all related to aerospace.

How many examples do you know about aviation?

Here's why.

With the enhancement of the country's strength, it has continuously increased its investment in aviation, but because of the short time and too many debts, the results are not very large. It can be said that aviation is another big shortcoming of our country.

The aircraft technology mastered by Ye Chen just made up for another shortcoming of our country. It will not only make up for a major shortcoming of our country, but also make our country a world aviation power in one fell swoop.

This future is so wonderful, Ye Chen had to be happy, and hummed a song: "We ordinary people, we are so happy today!" What a pleasure! ”

The helicopter part, because of the general environment, has not had much effect. Up to now, the more famous one in our country is Wuzhi 10, which is at the same level as the American Apache.

Apache helicopters have been around for decades, and we're only at the same level as we can get our hands on now, which is a bit of a shame to say.

Ye Chen's mastery of helicopter technology, throwing off Apache for dozens of hundreds of years, Ye Chen shook his head and sang: "From now on, Apache is a fart!" The best helicopter is the Celestial Empire! ”

Helicopters are extremely versatile, and have good prospects for both military and civilian use.

Heavy helicopters, in particular, are of particular importance for our country. As we all know, after the earthquake, our country needs to dredge the dammed lake, and there is not such a big helicopter to lift the machinery up, so we have to ask Mao Xiong for help, Mao Xiong sent the world's largest helicopter to help us lift the mechanical equipment up, which successfully dredged the dammed lake.

The helicopter technology that Ye Chen mastered and lifted dozens of tons of things was not a problem.

The large aircraft surprised Ye Chen even more, no matter in terms of flight speed, the load capacity is a big step up from the existing aircraft, and it can completely achieve supersonic flight.

There are many fighters capable of flying at supersonic speeds, but in the civilian sector, only the Concorde and Tu144 can fly at supersonic speeds, however, these two aircraft have been discontinued. On the civilian aircraft of the world today, there are no supersonic aircraft.

What does it mean that large aircraft are capable of reaching supersonic speeds?

It means that the transport aircraft will also reach supersonic speeds, which is wonderful.

Today's transport planes are generally subsonic, which will drag down the fighters, and the fighters must not slow down and wait for him, or escort them, which makes the speed of the fighters not be able to play to the extreme.

If transport aircraft can also reach supersonic speeds, then the aviation units will have a stronger ability to maneuver, a stronger ability to penetrate defenses, and even more difficult to deal with.

Think about it, if our country masters this kind of large transport aircraft and converts it into a tanker aircraft, it will be able to keep up with the speed of our fighters, and the United States will not have to cool up the back of its neck?

Not to mention that there is a longer range and a larger carrying capacity, which will make the combat power of the aviation units stronger.

As for the aerospace plane, not to mention, it is unique to our country, the only one in the world, and there is no semicolon. If it is built, it will become our country's strategic weapon, and the United States will dare to jump up and down again.

If the United States dares to do anything again, our country will send an aerospace plane to the skies over the United States. Just as not long ago, our country's launch vehicle walked around the United States, and the United States will be very nervous and will feel a chill in the back of its neck.

As for drones, our country is behind and has already laid a ground, and our country's drones have been sold internationally well. With this kind of technology mastered by Ye Chen, then it is not a problem for our country's drones to rule the world.

High-speed flying machines, now only the United States of the Celestial Empire and the fighting nation can develop them, and the three countries are engaged in fierce competition.

The fighting nation is now holding Mach 5 alone, and the Celestial Empire and the United States are competing for Mach 10~~20, and the winner has not yet been decided.

Ye Chen has mastered this high-speed aircraft technology, which has made our country's high-speed aircraft technology go up several levels, and the United States is not an opponent at all.

As long as Ye Chen is willing, he can completely increase the speed of the high-speed aircraft to more than Mach 20 and throw off a few streets in the United States.

At that time, our country will have an even greater advantage.

High-speed aircraft, like aerospace aircraft, are strategic-class weapons. With such a fast speed, it is impossible to intercept it at all, and if it is dropped on a target of great strategic value with a bombshell, there is no need to think about the consequences.

If you bring nuclear weapons again, let alone throw them down, or go up to other countries' territorial countries, it is estimated that they will scare this country half to death.

If it is really made, will the United States dare to be arrogant? (To be continued.) )
