The amount of data taken by a digital camera is quite large, even if it is just a grayscale image, each pixel needs 8 bits, that is, one byte to represent, and if it is a color image, it needs three bytes.

Even if a camera with 400,000 pixels, a photo is 1.2 million bytes, which translates to more than 1 trillion.

Even if the capacity of 1GB is often used in later generations, it is only a few hundred photos, and now, the mainstream hard disk is a capacity of hundreds of megabytes, and the memory card in a digital camera can have tens of megabytes.

Therefore, if you want to transfer photos, you must compress them, and according to a certain algorithm, the storage amount will be greatly reduced, such as jpeg, png, etc., which are all compressed formats. The principle is also very simple, for example, the pixels with the same color, record the position, and then record a color value, if half of the background images of a picture are the same, then the space can be directly reduced to half of the previous one.

And that's just the photo, if it's a moving photo or a video, it's even more compressed, and it all needs to be done with hardware.

Although Loongson has a multimedia instruction set in it, it can also be compressed, but it is too slow, and it still needs a professional chip.

In the future, when civil video recorders, civil VCDs and other machines rise, similar chips will also be needed, so now this kind of chip can continue to occupy the civilian market.

The other is the communication chip, which also needs to be specially developed, after all, most of the radios in this era are transmitted analog signals, and in the later era, digital signals need to be transmitted, these are blanks, and they are also the most profitable electronic fields.

When these are all in place, the DJI drone will be truly mature, with practical value, and it is not just a toy like before.

Of course, considering that the mobile phone is still just a big brother like a brick, it can only be transmitted back to the computer first, and the notebook is not realistic, it can only be a desktop.

Li Runzhu nodded: "In this way, the front-line reconnaissance mission of our army can be handed over to your DJI drones, or your private enterprises have the strength to come up with all kinds of equipment." ”

The others didn't speak.

I knew that I wouldn't come to dinner, at this dinner table, there was no opportunity for others to speak, Qin Feng was the focus!

Looking at it this way, the troops are properly going to choose the big eight, and they have studied for so many years, and it has been in vain.

Forget about 551, after all, it was invested by the state, and the big eight wheels of the Iron Horse Factory, which was completely self-funded, for them, this blow was the biggest.

"Yes, if the relevant units of our weapons industry and the drones researched are all normal aircraft styles, there will definitely be no bold innovation of quadrotor drones like yours, and our country supports private enterprises, there is nothing wrong!" Ma Bonian spoke.

State-owned enterprises are conservative, and there will never be any unit to think about innovation, or this new quadcopter UAV, the innovation ability of private enterprises is the first!

Wang Pengfei's eyes rolled, and he said: "In the future, we will have the same common data link of the three armed forces as NATO, and the situation ahead can be directly displayed through aircraft reconnaissance, and even directly connected to satellites, this drone ......"

"This drone isn't just about reconnaissance." Qin Feng smiled, he knew what Wang Pengfei wanted to express, he had to give the big guy a science popularization: "In the future, our drone can also hang a bomb, even if it is just a grenade, it can also fly to the top of the enemy's head and throw it down, for some people hiding behind buildings, or in trenches, drones will be their nightmare." ”

Just look at the Ermao battlefield in later generations, drones are definitely a nightmare for many soldiers.

What do you say about the common data link of the three services, can it work?

"Even for some snipers who hide in the building and shoot cold guns, our drones can fly in and blow them up directly, even if the drones are blown up because of this, don't worry, and when they are mass-produced in the future, the price of our drones will be reduced, and the price of a simple drone used as a bomb is two thousand yuan, just a shell."

Li Runzhu's eyes widened: "That's right, where the front-line mortars can't hit it, this small plane can fly in!" And the price is cheap, it can be used as a consumable, Xiao Feng, your Pacific Group is really a good partner of our army! ”

Fighting a war is to burn money, an ordinary large-caliber grenade costs one or two thousand yuan, if it is a tungsten alloy armor-piercing projectile, one will cost more than 10,000 yuan, and the cannon can not appear behind the infantry all the time, the infantry has this drone, it can definitely be like a tiger!

"What flies in the sky and runs on the ground, you Pacific Group can build it, and you can swim in the water, you can also mix in, your Pacific Group is the largest military industrial group in the East!" Ma Bonian said with a smile.

"No, no, we only produce civilian products." Qin Feng shook his head modestly: "The product that came to bid today, referred to as the big eight-wheeled, the official bidding name is the wild high-performance protected eight-wheeled off-road vehicle, which mainly meets the needs of customers such as oil, exploration, and tourism in the wild. ”

The other bidding units only had to roll their eyes, what civilian products, see which civilian goods company will purchase armored vehicles like yours, which are obviously for the army, and they are still installed!

"By the way, in order to improve the safety of field operations, our big eight-wheeled can also be installed with a variety of self-defense supplies, conventional vehicles are only equipped with 30mm machine guns, but if the troops need it, they can also install other weapons, such as 105mm tank guns."

Everyone's eyes widened.

What are you kidding, a wheeled infantry fighting vehicle actually carries a 105-mm tank gun? Isn't this turning into a wheeled tank? Will the chassis withstand it when firing? Will it roll over?

"Installing a 105mm tank gun on a twenty-ton wheeled chassis, Mr. Qin, the imagination of your private enterprises is really rich enough!" Wang Pengfei spoke.

"Ahem, our big eight wheels are indeed twenty tons, but this is just a naked car, the armor of our car has a modular design, the basic version only has a steel plate shell, the weight is only a dozen tons, according to the needs of the composite armor can be added, it can become a twenty-ton upgraded version of the vehicle, if you face a more dangerous situation, you can also hang ceramic armor outside, upgrade the weight to thirty tons, and become a heavy version."

Why a 500-horsepower engine? Not only to make the car run fast, but also to make the car have plenty of power reserve!

The car can travel lightly and can also increase protection!

Isn't it just an infantry fighting vehicle, and you actually play different styles? Everyone's eyes widened, this trick is indeed only played by private enterprises.

"The upgraded version should be a model normally purchased by the troops, let's take this model as an example, the front can block a 23 mm armor-piercing incendiary bomb from a thousand meters away, and the side can block a 12.7 mm armor-piercing incendiary bomb from a hundred meters away."

This data shocked everyone.

"If it becomes a reloaded version, then we will be able to block 35 mm armor-piercing incendiary shells at a distance of 1,000 meters on the front of the hull, and 20 mm armor-piercing incendiary shells on the sides at a distance of 100 meters. I wonder how well the infantry fighting vehicles of our fraternal units are protected? ”

No one answered.

Wang Pengfei also lowered his head, their WZ551 infantry fighting vehicle could only block the blow of 7.62 mm bullets, and even if they encountered a 12.7 mm caliber machine gun on the battlefield, they could be punched out one hole after another.

"Such a strong protective force? Can I test it? ”

"Of course, we also brought a ceramic kit for heavy equipment, and if the troops need it, they can be displayed on the spot." Qin Feng puffed out his chest proudly: "I'll just sit in the car and let you fight!" ”

That's absolute confidence!

At the beginning, the Pacific Group had just started, and it made the world's first ceramic body armor, and the soldiers in the south each had a piece, and they were full of praise for this kind of body armor! At the same time, a large number of exports are also made, and it is often a small target order.

Even when Zhu Lao was developing the third-generation tank, he came to the door to ask for advice to see if they had suitable armor materials for tanks.

On other R&D units, it is necessary to go to the brother units for coordination, but for the Pacific Group, there is no need to be so troublesome, and it is completely self-reliant to solve all the supporting projects by itself.

Wang Pengfei didn't speak at all, how can he compare, compare to a hammer!

Just then, an officer quickly ran in.

"Report, the capital sent a telegram, asking Mr. Qin to return to the capital immediately!"

"What?" Qin Feng was stunned, he was still waiting for the next test project to show his skills! Why did you suddenly call yourself back?

Is there an emergency? Gillian body ...... Thinking of this, Qin Feng stood up: "Okay, then please prepare a car for me immediately, Lao Xing, the bidding task here is handed over to you!" ”

Xing Fuqiang hurriedly stood up: "Mr. Qin, we promise to complete the task!" ”

"Send a Mountain Eagle from the base to take you to the nearest air force airport, and the air force will send a plane to pick you up."

Wait, something is wrong, Air Force?

It's not a family thing!

Qin Feng was full of fog, and sat in the air and went to the air force airport with three jumpers, along the way, Wang Hu, who was driving in front, kept talking, all of them were emotional.

"Mr. Qin, I was stunned when I saw your armored car flying over that big rift valley today!"

"Mr. Qin, the suspension of your big eight wheels shouldn't be the landing gear of the plane, there is nothing to do when you go down."

"Mr. Qin, Mr. Qin, why don't you speak, you shouldn't fall down, right?"

Wang Hu turned his head and glanced back, Qin Feng was already asleep on the seat, he was too tired.

Early the next morning, Qin Feng came to the airport, and when he waited for the Air Force car to pick him up, he bought a newspaper.

Headlines on the front page: Lao Maozi's chief planner Shaposhnikov publicly stated that Lao Maozi allowed the East to buy MiG-29s from them!

It turned out to be this thing! Qin Feng thought something had happened to his pregnant wife!

The door to the West is closed, and the door of Lao Maozi is open!

In order to win over the East, Lao Maozi decided to export "advanced" MiG-29 fighters to the East, but will the East like it?

Of course not! We have J-10, we have Thunder, who would like a short-legged plane! However, we already have the J-11, do we still need a similar heavy fighter Su-27?

It's a tough choice!

The Air Force must have been caught in an argument, so they called Qin Feng over, wanting him to help come up with an idea, this kind of offending work has to fall on his head again?

Thinking of this, Qin Feng was a little speechless.

"Mr. Qin, I'm very sorry, I'm late." Lin Lao's personal secretary, who came to greet Qin Feng, ran all the way.

"So far?" Qin Feng asked curiously.

"How do you know?"

"The smell of smoke all over my body, my eyes are bloodshot, and I look like I haven't slept all night! In that case, send me home first, you can sleep first, and when you have rested enough, I will go over. ”

"Mr. Qin, there is no result from the discussion of this matter, no one can sleep, our meeting was held from yesterday morning to evening, and there was no result, Lin Lao proposed to call you back, and he planned to break up the meeting at that time, but no one listened, and he was still discussing there, and it is now."

"Okay, I'll take a look."

Princess Tomb, Airplane Building, Conference Room.

When Qin Feng walked in, he almost didn't choke him and turned around and left.

"Are you guys filming Journey to the West?"

"Xiao Feng, you're here!" Lin Lao poked the cigarette butt into the ashtray: "Let's stop smoking, open the window and disperse the smell of smoke, Xiao Feng has to go home after the meeting, but I can't let my pregnant wife smell the smoke on her body." ”

Lin Lao's politeness? There must be something to ask for!

"Mr. Qin, this time Lao Maozi has spoken, allowing us to officially purchase MiG-29 from Lao Maozi, we are discussing, whether to go to Lao Maozi to inspect it, if you think it is appropriate, buy a batch, and at the same time introduce a production line for independent production."

It was Li Ming who spoke, full of energy, don't look at the days and nights, he is still in good condition.

This time, we must convince the Air Force to seize this rare opportunity to achieve leapfrog development of equipment!

Last time, they put forward a proposal to introduce the MiG-29, but it was vetoed by Lin Lao on the spot, on the one hand, the troops were not satisfied with the performance of the MiG-29, on the other hand, this kind of thing was completely wishful thinking, and Lao Maozi didn't know what he thought.

But now it's different.

Now you can buy it for just a few dollars!

"As for the range of the MiG-29, we have also investigated, the internal fuel tank of this aircraft is indeed not much, the main fuel is stored on the wings, plus four fuselage fuel tanks, a total of 4365 liters of fuel, but if you want to increase the range, you can carry a 1,500-liter drop fuel tank on the belly centerline, and each side can carry a 1,150 liter drop fuel tank under the wings."

Li Ming introduced: "In this way, the range of the MiG-29 can also be extended to 2,500 kilometers, which can fully meet our needs." ”

In fact, the low fuel carrying coefficient is not a big problem, and it is enough to add an auxiliary fuel tank.

The ratio of the fuel weight of the aircraft to the take-off weight is the fuel coefficient, in the field of fighter aircraft, the Su-27 is quite strong, with a fuel carrying coefficient of 40 percent, and the facelifted Su-34 has reached 46 percent, and less than half of it is oil when it takes off!

Lower than it is the F-35, with a fuel load factor of 37 percent, relying on advanced aero engines, so that the fertilizer electric can also fly long enough.

For example, the fuel carrying coefficient of the third-generation aircraft is generally within 30 percent, for example, the fuel in the aircraft of the F-15 in the United States is only six tons, even if it is only calculated with a take-off weight of 20 tons, the fuel carrying coefficient is also below 30 percent.

The French plane is even more, every time the Rafale fighter appears, almost all of them will be hung with three large auxiliary fuel tanks, which look like big bombs, mighty and domineering, but in fact, it is completely because of the small body, the fuel in the plane is only 4.5 tons, and it is impossible to fly far without the auxiliary fuel tank when you go out.

The MiG-29 can also be like this, the fuel in the aircraft is not enough, let's hang the auxiliary fuel tank to make up!

Last time, Lin Lao vetoed it, because of the lack of range, and now there is a plan to plug in the auxiliary fuel tank, and the range problem is solved, and the biggest obstacle is eliminated!

Although this meeting was held in the aircraft building, almost all of them were led by Li Ming, and he repeatedly introduced how good and powerful the MiG-29 was!

"Mr. Qin, I heard that you have started the mapping and imitation of RD33, and when this aircraft is introduced, we will have an engine, and we will not worry about heart disease." Li Ming continued.

The meaning is also very clear: as long as you support, we can make money together!

Qin Feng smiled: "This project hasn't started yet, the most important thing for us at present is to copy the third uncle's engine surveying and mapping." ”

rd33 can make money, and so can the third uncle! Moreover, these two are contradictory, one is more, the other is less, no matter which one, it is our Pacific Group!

Lin Lao stood at the window, blowing a cold wind to sober himself up, and at the same time watched to see what Qin Feng had to say.

Qin Feng naturally didn't want to dwell on it, so it would be endless, and it wouldn't work for another day!

"Actually, there is no point in talking about it here." Qin Feng quickly cut through the mess: "Since Lao Maozi said that he could sell us the MiG-29, then send a plane over and show us something!" When we watched the F-16 and the Mirage 2000, didn't they all show flights? ”

"That's right!" Lin Lao nodded: "Hearing is false, seeing is believing, only after seeing can we determine whether we meet our needs." The next task is to invite Lao Maozi to come to us to show the flight, let's see it, and then dismiss the meeting! ”

This day and night is really torture! The main thing is that Li Ming has been bypassed, and all kinds of rhetoric continue, just to let the Air Force buy it, and to introduce the production line, now Qin Feng said in one word, it is useless to hold a meeting here! I'll have to see it!

"Lin Lao ......" Li Ming still wanted to say something.

"Without an investigation, there is no right to speak, and after reading it, we will talk about it!" Boss Lin strode out: "Xiao Feng, you come with me!" ”

Qin Feng was also speechless, he had known that he would only say a word, so he would send a telegram back, and our big eight rounds over there would still be a test! Isn't that a delay?
