Chapter 794 No? Then write one

Liu Hai's family all wore masks and hats, and were led by a special person.

The reason for wearing masks and hats is that it is cold, and on the other hand, it is also for covering up. After all, if a family of all ages comes here alone, it is easy to attract other people's attention.

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

This fighter jet is parked in the hangar. Its modern paint job gives people a very threatening feeling, just like the black shadow that many people saw appearing in the water from afar.

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

The fighter jet doesn't look very big in the sky, but it is still a huge guy when you look at it up close.

The aircraft is 21.9 meters long, 14.7 meters wide and 5.93 meters high.

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

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

The three little ones at home have their eyes wide open and it’s not enough to look at them.

"The maximum take-off weight can reach more than 30 tons, it can carry about 8 tons of ammunition, and its combat radius is 1500 kilometers."

"This means that without refueling, our fighter jets can fly further until our tankers are finished."

"Fighter jets need to be refueled, I'm afraid they also need training?"

"This is natural."

"Our country is also able to produce such advanced fighter jets. It is really advancing 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-jet technology, which is cutting-edge technology in 2020, let alone now in 85.

"Every time we tackle technical problems, we gain leadership." Liu Hai knows that we are currently using shaft pump push technology.

Liu Hai mentioned this before, which is to add a cover outside the rear thruster.

This shaft-type pump-propelling technology is considered cutting-edge technology today, not to mention the shaftless pump-propelling technology. Foreign countries are still using the large seven-blade type.

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

Because there is no need for a mechanical transmission shaft, the noise itself will be reduced to a very low level.

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

"Don't bother me watching planes. I must fly fighter jets in the future. Give what you watched last time to my sister."

"This is a national aircraft. Not only does it have to pass the test, but it also has to be in good health."

"I will study hard for the exam. Don't disturb me watching the planes here." The third child stopped his mother from nagging in his ear.

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

"I'm the chief designer." Liu Hai nodded.

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

"There are so many things to learn, but you should work hard first and then 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, but it’s a pity that the bangs can’t fly up.

This thing is only powerful when flying at supersonic speed, and it is most suitable for people with a strong physique to fly this.

Then we arrived at a hangar, which was ready for taking photos. There were many missiles placed in front of the fighter jets.

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

Liu Hai felt a little regretful when he saw these missiles, because now there were only air-to-air missiles and combat missiles.

By 2020, it will be able to carry not only smart bombs, but also anti-radiation missiles, electronic pods, and so on.

But these missiles are quite large, and don't be fooled by the fact that they look like toothpicks on the plane.

These hardpoints are capable of carrying missiles weighing 800 kg.

When the electronic pod is completed in the future, it will take the Black Shark fighter's combat effectiveness to a higher level.

Then the group watched the fighter jets take off at close range, although of course this distance was definitely within a safe range.

The whole family watched in unison as the plane quickly passed by the runway in front of them and then took off.

Although the fighter jet is carrying simulated bombs, the thrust of the aircraft is still there.

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

Unfortunately, the Cobra maneuver is not shown here.

The Cobra maneuver is also known as the super-stall maneuver, and it was first successfully tested by Su-27, the Su- of the USS Florida.

Historically, in June 1989 at the Paris Air Show, the famous fat bear test pilot Viktor Pugachev performed the Cobra maneuver in front of the whole world for the first time, so this maneuver is also called the "Pugachev Cobra" maneuver.

During the maneuver, the pilot quickly pulls the stick back to pitch the nose up to between 110 and 120 degrees, creating a short period of level flight with the tail in front and the nose in the back. The pilot then pushes the stick to press the nose down and returns to its original horizontal state.

During the maneuver, the aircraft entered at a speed of approximately 425 kilometers per hour, 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 withstand 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 maneuver exposed a larger area to the side radar, so this legend was basically false.

However, there is another action, the falling leaves, which was discovered and summarized by the test pilot during the test flight.

"Falling leaves" is also called "no-radius descending turn super maneuver". It is a turning maneuver with a small radius or even no radius or zero radius. It is like leaves falling from a tree. The movement is elegant and beautiful, just like leaves falling to the ground.

This can be traced back to 1970 when a Bald Eagle pilot parachuted out after discovering that the F106 aircraft he was flying had stalled. Unexpectedly, the aircraft automatically recovered 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 move dates back to 1905, when it was first performed by a Bald Eagle man named Daniel Maloney.

Maloney, who was performing a glider at the Expo, failed to control the turning range of the aircraft, causing the aircraft to flip over during the sharp turn and even the wings to twist. Maloney made this move inadvertently in a hurry, which avoided the crash.

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

Then there is the death circle flight. In August 1913, Nesterov performed a maneuver of his own design in a glider.

In fact, many of the subsequent flight stunts are often caused by problems with the aircraft during the test flight, which are then solved by the pilots.

In later generations, various aircraft used these difficult maneuvers to prove their superior performance. How could there be no Cobra Excitement maneuver?
Liu Hai thought about it for a while and prepared to explain the technical points of this action.

Just like the death circle, this is an action that was thought up by humans and then realized.

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

The family didn't bother with the bangs.

Liu Hai simply drew the Cobra maneuver with his hands.

Then he quickly marked the key points of the action.

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

The staff member, also wearing a mask, nodded when he saw the Cobra maneuver written in the notebook, along with the pictures and instructions.

"Let's go." Liu Hai said.

"Isn't there an air show?"

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

On the one hand, this is the first time I’m filming a performance. What if I mess up in this place?
In addition, there are important factories and densely populated villages everywhere around here.

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

But this time we are mainly shooting 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 real show to watch." Liu Hai said with a smile.

The higher authorities attached great importance to this maneuver proposed by Liu Hai.

However, we will not rush into a test flight just because Liu Hai brought it up.

The pilots also have to take a look at it themselves, and then after a series of evaluations, the test flight can begin.

What Liu Hai didn't know was that because he added the Cobra maneuver, even though the shooting was completed, it was not broadcast yet.

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

Moreover, it was very convenient to eat at that time. You could just order takeout. It was not like now when you have to queue up if you want to go to a Western restaurant to eat steak or something.

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

In foreign countries, everyone has their own preferences. Some like it 5% done, some like it 7% done. There is no regulation. For example, Emperor Entertainment Group likes to eat it well-done.

When you bring it back home, they say this part must be eaten medium-rare, and you won’t eat it if you want it medium-rare.

In his previous life, Liu Hai had been to many countries and many places, and the steaks there were not only cooked to perfection, but were also cooked to the point of being soft and rotten.

Later on, Liu Hai rarely ate domestic steaks because most of them were fried in Teflon non-stick pans, which were called Teflon steaks.

Hot pot is a double-boiled pot. You can have it spicy if you want it, or not spicy if you want it. As for the dipping sauce in the bowl, that is a personal preference.

"Xiao Hai, the wine you stored is really good." Liu Hai took out a few more bottles of aged wine and gave them to Zhu Haiyang.

"If you want to drink, that's fine."

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

"almost."

"I never thought I would achieve what I have now, nor did I expect my daughter to achieve what she has 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 encouragement that I entered the research field. Your thinking and direction are so important in research."

"I don't know the details of my daughter's research, but I know you must have made great contributions."

"Teacher, we are one family and don't have different opinions. Everything is in the cup." Liu Hai was drinking hawthorn drink, which he drank during the Chinese New Year to help digestion.

"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 the drink and poured a glass for Master's wife, and then poured himself a glass.

"Xiao Hai, you gave us a lot of good things back then. Your factory had good performance and good welfare. I still remember the various things you brought us. When we cooked and ate them, the neighbors around us looked envious." The master's wife also picked up the cup.

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

"You're too polite, Master's wife." Liu Hai had another drink with Master's wife.

Then the junior sister had another drink with her parents.

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

Liu Hai and his brother-in-law just clinked glasses and didn't say anything else.

"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 can't spend all my dad's royalties in my lifetime."

"Get lost. Donate my royalties when I die." Zhu Haiyang was very clear-headed today.

"Then I will collect rent. I will collect rent from all the houses I have." The brother-in-law didn't care.

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

Then, the junior sister grabbed him by the ears and said, "You are still supporting others. You are so bad at studying now. You will be a rag picker in the future."

“I can study well.”

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

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

Since my junior fellow apprentice is interested in this area, I can guide him to start a computer game company in the future.

Liu Hai did not expect his junior fellow apprentice to surpass himself, his junior sister or his teacher in the field of scientific research.

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

Unless there is a cheating guy who is reborn, everyone else will have to wait in line obediently.

"My brother-in-law is the best to me. I'd like to offer a toast to him." The younger junior brother saw that his brother-in-law had spoken, and his father did not object.
