Chapter 794 No? Then Write One

Liu Hai's family all wore masks and hats, and were led by someone.

The reason for wearing masks and hats was that it was cold, and on the other hand, it was also to cover up. After all, it was easy to attract other people's attention if a family of young and old came here alone.

First, we came to the hangar of the Black Shark fighter. The Black Shark fighter with modern paint looked like a ferocious shark.

This fighter was parked in the hangar. The modern paint gave people a very threatening feeling, just like many people saw a black shadow appearing in the water from a distance.

"Tsk tsk!" Zhu Haiyang touched the Black Shark plane with gloves.

The fighter does not look very big in the sky, but it is still a huge guy when viewed from a close distance.

The length is 21.9 meters, the wingspan is 14.7 meters, and the height is 5.93 meters.

People standing in front of them look very small, especially the Black Shark fighter, the tall cockpit is particularly conspicuous.

"It looks small on TV and in newspapers, but I didn't expect it to be so big in reality." Zhu Haiyang still knows how to speak.

The eyes of the three little guys at home are already wide open, and they are no longer enough to look at.

"The maximum take-off weight can reach more than 30 tons, it can carry about 8 tons of ammunition, and the combat radius is 1,500 kilometers."

"This refers to the situation without refueling. When our tanker is completed, our fighter can fly farther."

"I'm afraid that fighter refueling also requires training?"

"This is natural."

"Our country can also manufacture such advanced fighters, which is really changing with each passing day."

"Teacher, the research you do is the most cutting-edge."

"Alas, my project is progressing very slowly, and many problems need to be solved one by one." Zhu Haiyang shook his head.

"In terms of teacher's research, we are already far ahead of foreign countries." Liu Hai was talking about the shaftless pump-thrust technology, which is cutting-edge technology in 2020, not to mention now in 1985.

"One after another technical breakthrough means one after another leading." Liu Hai knew that we are now using shafted pump-thrust technology.

Liu Hai mentioned this before, that is, adding a cover outside the rear thruster.

This shafted pump-thrust technology is considered cutting-edge technology now, not to mention shaftless pump-thrust, which is still used in foreign countries.

However, shaftless pump propulsion can only use nuclear power, because it does not need a mechanical transmission shaft, but only electricity.

Because it does not need a mechanical transmission shaft, the noise itself will be reduced to a very low level.

"Third brother, do you see this? This is the most advanced one." The junior sister patted the third brother on the side and said.

"Don't disturb me from watching the plane. I must fly a fighter in the future. I will give the last time I saw it to my sister."

"This is a national aircraft. Not only do I have to take the exam, but I also have to be healthy."

"I will definitely work hard for the exam. Don't disturb me from watching the plane here." The third brother stopped his mother from nagging beside his ear.

"Dad, is this what you are doing?" The second brother Xiaofeng asked mysteriously in a low voice.

"I am the chief designer." Liu Hai nodded.

"So what should I learn if I want to build an airplane in the future?"

"There are too many things to learn, but you should work hard first and talk about it when you take the college entrance examination." Liu Hai said.

Then, under the guidance of the staff, the family took turns sitting on it to experience it.

This is already a very rare experience. It's a pity that Liu Hai couldn't fly.

This thing is only powerful when it flies at supersonic speed, and my strong physique is most suitable for flying this.

Then I went to a hangar, which was ready to take pictures immediately. There were many missiles in front of the fighter.

"Tsk tsk!" Of course, these missiles are models. Zhu Haiyang didn't know what to say when he saw that this plane could carry so many ammunition.

Liu Hai felt a little sorry to see these missiles, because now there are only air-to-air missiles and combat missiles.

In 2020, not only smart bombs can be hung, but also anti-radiation missiles, electronic pods, etc.

However, these missiles are not small. Don't look at them like toothpicks on the plane.

These mounting points can hang 800 kg missiles.

When the electronic pod is completed in the future, it will raise the combat effectiveness of the Black Shark fighter to another level.

Then the group watched the fighter take off at close range, of course, this distance must be at a safe distance.

The family watched the plane pass quickly on the runway in front of them and then directly pulled up.

Although the fighter jet is equipped with simulated bombs, the thrust of the aircraft is here.

A staff member handed Liu Hai a piece of paper, and Liu Hai looked at it carefully. ,

"What is this?" Zhu Haiyang saw Liu Hai looking at a piece of paper.

"This is the flight performance action during the publicity. Through this action, the performance of the fighter jet can be intuitively demonstrated." Liu Hai said.

Unfortunately, the Cobra maneuver did not appear on it.

The Cobra maneuver is also called the stall maneuver. In history, the Su-27 of the Fat Bear was the first to successfully test fly.

In history, at the Paris Air Show in June 1989, the famous test pilot Victor Pugachev performed the Cobra maneuver in front of the world for the first time, so this maneuver is also called the "Pugachev Cobra" maneuver.

During the maneuver, the pilot quickly pulled the stick back to make the nose of the aircraft pitch up to between 110 and 120 degrees, forming a short-term level flight state with the tail in front and the nose behind, and then pushed the stick to press the nose, and then returned to the original horizontal state.

During the maneuver, the aircraft entered at a speed of about 425 kilometers per hour, and the aircraft decelerated at a rate of more than 148 kilometers per hour, and then decelerated to 110 kilometers per hour. This action only caused the aircraft to bear an overload of 3.5 to 4g. During the entire maneuver, the aircraft's flight altitude hardly changed.

At that time, many people believed that the Cobra maneuver could evade enemy missiles, but later in many tests it was found that this action exposed more area to the side radar, so this legend was basically false.

However, there is another action, the falling leaf drift, which was also discovered by the test pilot during the test flight and then summarized.

"Falling leaf drift" is also called "no radius descending turn super maneuver", which is a small radius or even no radius, zero radius turning maneuver, just like leaves falling from a tree, the action is elegant and beautiful, just like leaves falling to the ground.

This can be traced back to 1970 when a pilot of the Bald Eagle found that the F106 he was driving stalled and jumped out of the plane. Unexpectedly, the plane automatically turned out and landed in a cornfield.

The plane weighing more than ten tons was only scratched.

Then there is the barrel roll, which can be divided into offensive barrel roll and defensive barrel roll.

This action can be traced back to 1905. The first person to complete this action was a Bald Eagle named Daniel Maloney.

Maloney, who was performing in a glider at the Expo, failed to control the turning range of the aircraft, causing the fuselage to flip during the violent turning process, and even the wings were twisted. Maloney made this action accidentally in a hurry, which avoided the crash.

Later, his companion David Wilk deliberately imitated this action and successfully completed the left and right rolls during the flight. The "barrel roll" action was finally formed.

Then there is a death loop. In August 1913, Nesterov flew a glider to perform a move of his own design.

In fact, many of the later flying stunts are often formed after the aircraft has problems during the test flight and the pilots solve them.

In later generations, various aircraft use these difficult actions to prove the excellent performance of their fighters.

How can there be no Cobra excitement action?

Liu Hai thought about it and prepared to talk about the technical points of this action.

Just like the death circle, this is an action that people thought of and then realized.

So Liu Hai borrowed a pen and a notebook from the staff, and then started writing and drawing.

The family did not disturb Liu Hai.

Liu Hai simply drew a picture with his hands and drew the Cobra maneuver.

Then he quickly marked the key points of the action.

"This is a move I thought of." After Liu Hai finished writing and drawing, he signed his name and handed it to the staff.

The staff also wore a mask and nodded when they saw the Cobra maneuver written on the notebook, as well as the picture and explanation.

"Let's go." Liu Hai said.

"Isn't there a flight show?"

"That's not happening here, it's happening somewhere else where there's no one. This place is too sensitive." Liu Hai certainly wanted to watch a fighter jet performance like in the future.

On the one hand, this is the first time to film a performance. What if the performance fails here?

In addition, there are important factories and densely populated villages everywhere around here.

Because the plan was not to perform here this time, it might be because Liu Hai was too anxious.

But this time it's mainly to shoot a promotional video, and we can watch it when we participate in the air show later.

Besides, there is no Cobra maneuver.

"Don't worry, there will be a time to watch the performance in person." Liu Hai said with a smile.

The superior department attaches great importance to the maneuver proposed by Liu Hai.

However, they will not rush to test the flight just because Liu Hai proposed it.

The pilots will have to see it for themselves, and then they will start the test flight after a series of evaluations.

What Liu Hai didn't know was that because he added the Cobra maneuver, although the shooting was completed this time, it was delayed and not broadcast.

We had hot pot at Zhu Haiyang's house in the evening. In his previous life, Liu Hai ate food from all over the country because there were so many food in Kyoto.

And it was very convenient to eat at that time. You could just order takeout. It's not like now that if you want to go to a western restaurant to eat steak, you have to queue up.

Many people have always thought that foreigners eat half-cooked steaks, but in fact, many people abroad also eat well-done steaks.

In foreign countries, everyone has their own preferences. Some like to eat 5 points, some like to eat 7 points, and there is no regulation, just like Emperor Entertainment Group likes to eat well-done.

In China, it becomes a fancy way to say that this part must be eaten three-point rare, and you won't eat it if you want to eat medium rare.

In his previous life, Liu Hai went to many countries and many places. The steaks were not only well-done, but also cooked soft.

Later, Liu Hai didn't eat much steak in China, because most of them were fried in Teflon non-stick pans, which are called Teflon steaks.

Hot pot is a double-flavored pot. If you want to eat spicy, you can eat spicy, if you want to eat not spicy, you can eat not spicy. As for the dipping sauce in the bowl, this is a personal preference.

"Xiao Hai, the wine you saved is really good." Liu Hai gave Zhu Haiyang a few more bottles of old wine.

"As long as you are willing to drink."

"Come, let's have a drink. It's been almost 30 years since we met."

"about there."

"I didn't expect that I would achieve what I do now, and I didn't expect that my daughter would achieve what she does now. In fact, it's all because of you."

"Don't say anything. I originally just wanted to be a teacher. It was with your push that I entered the research ranks. Moreover, your sense of thinking and your sense of direction are so important in research."

"I don't know the details of my daughter's research, but I know you must have put in a lot of effort."

"Teacher, a family does not speak two different languages, everything is in the cup." Liu Hai drank hawthorn drink, which is consumed during the Chinese New Year to eliminate food.

"Everything is in the cup." Zhu Haiyang nodded and drank the wine in a small cup in one breath.

"Master's Wife, thank you for taking care of me for almost 30 years." Liu Hai picked up another drink and poured one for his wife, then another for himself.

"Xiaohai, you gave us a lot of good things back then. Your factory was very profitable and had good benefits. I still remember the various things you brought us. The neighbors around us looked envious when we were making them. ." The teacher's wife also picked up the cup.

"I just didn't expect that we would be able to go through so many years together."

"Master's wife, you're welcome." Liu Hai had another drink with Master's wife.

Then the junior sister had another drink with her parents.

The three little guys also want to have a drink with grandpa and grandma.

Liu Hai and his brother-in-law just had a drink together and said nothing.

"Brother-in-law, do you have any new computer games?"

"Yes, I have?"

"Can you take me to experience it?"

"Are you interested in games?"

"Anyway, I won't be able to finish my father's royalties in my lifetime."

"Go away, I will donate the royalties when I die." Zhu Haiyang is smart today.

"Then I'll charge rent. I'll charge rent for all the houses I have." The brother-in-law didn't care.

"Uncle, I will support you from now on." Xiao Pomegranate said after finishing the drink.

Then the junior sister held her by the ear and said, "You still support others. If you are so bad at studying now, you will pick up rags in the future."

"I can study well."

"I'll take you to see it in a few days. In fact, computer games are a big development direction." Liu Hai nodded.

Who could have imagined how big the market for computer games would be in the future?

Since my younger brother is interested in this aspect, he can guide him to start a computer game company in the future.

Liu Hai did not expect his junior brother to surpass himself, his junior sisters or teachers in the field of scientific research.

I'm afraid it will be difficult for anyone to surpass my family of three.

Unless there are cheating guys who are reborn, they will all have to queue up at the back obediently.

"My brother-in-law is the best to me. I'll give you a toast." The younger brother saw his brother-in-law speaking, and his father didn't object.
