"Mr. Qin, you are really a genius!" Xing Fuqiang sighed with emotion: "We never knew before that in addition to the central drive shaft, this wheeled vehicle also has a scheme for placing drive shafts on both sides!" ”

Xing Fuqiang is extremely admired, when he opened his own factory, he just made a small fuss, changed to an old liberation or something, and now he follows Mr. Qin, and the ones he makes are all big guys, many of them have never been seen, but after they are built, they are still so suitable!

"Yes, with this design, the overall height of the car can be reduced by 30 centimeters under the condition that the passability remains unchanged!" Lao Wu also sighed on the side: "No, if you count the floor in the car, it can be lowered by 50 centimeters!" ”

Half a meter is enough to gain a huge advantage!

The lower the altitude for a vehicle on the battlefield, the harder it is to be detected. At the same time, due to the lower center of gravity, it is more difficult to roll over!

"I heard that the Iron Horse Factory is building a wheeled infantry fighting vehicle based on the Mercedes-Benz chassis, and there is still a thick propeller shaft in the center, and the chassis is tall, that kind of car definitely can't be compared with ours!" The sixth child is also emotional.

"Don't get too happy, this car has a lot of performance, but it also has a lot of unique needs, a central transfer case, a final drive, a differential, an overdrive clutch...... These technologies are very difficult, I promise the troops, three months to produce a sample car, we must not drop the chain! ”

"Mr. Qin, don't worry, we are professional in building special vehicles!" Xing Fuqiang said.

"That's right, we can't build airplanes, and cars are still fine."

Qin Feng smiled and bragged, you brag first, and when you encounter a problem, you will know how much headache it has!

There are many advantages of H-shaped transmission system, there are defects, all wheels on each side are mechanically connected together, with the same speed, when the vehicle turns, the differential effect can only be achieved through the differential on the engine side, but when the four tires on one side are turning, the trajectory of each tire is still slightly different, so that there will be the phenomenon of holding the wheels, especially on the hard road surface is more serious, and the central drive does not have this defect.

In order to change this defect, the junction of each side of the wheel also needs a special overspeed clutch to supplement the central differential, and more complex can also use a claw clutch, no matter what kind of clutch, now the country is a blank, and the Pacific Group needs to rely on its own ability to make it.

Anyway, let's build it first, and then talk about it, reliability, durability, and slowly improve.

In fact, in the later stage of the development of wheeled vehicles, diesel-electric hybrid is the most suitable solution.

This is not what new energy, environmental protection needs, but real technical needs, each wheel is equipped with a hub motor, so that there is no need for any gearbox, clutch, differential and the like, you can achieve the function of all-wheel drive, can not rely on the battery, after all, the military vehicle does not have time to wait for a few hours to charge, must use oil, but the engine can only work in the best range, the load is low, the excess power is charged, the load is high, and the battery provides additional power.

"Old Five, what you said is not right, our Pacific Group is not only making cars, we are also building airplanes, and our factory in Jincheng is making legs and bones for airplanes."

Qin Feng suddenly remembered that during this period of time, he seemed to have put all of his attention on building cars, and he didn't pay much attention to building planes, especially J-11, which should have been able to be produced in small batches at present, right?

What about big planes? If the Pacific Group wants to be an industrial hegemon, cars and planes cannot be delayed.

At this moment, a voice suddenly came from outside.

"Mr. Qin, someone is looking for you!"

"Who?"

"Me!"

With the voice, several people walked in, and when he saw the person in charge, Qin Feng immediately put down the work in his hand: "Old Song, when did you come?" ”

"I came here yesterday to report to the leaders of the capital, and today's meeting is finally over, so come and take a look, Mr. Qin, I heard that your Pacific Group has recently received more and more military orders!"

Qin Feng smiled: "The military order is not enough to stuff the teeth, and there are still many military enterprises that do not like us, we are a private enterprise, or mainly produce civilian products." ”

"Yes, even if you don't rely on the army, your Pacific Group can develop and grow, your ability to make money is really powerful, we are different......"

"Lao Xing, you guys are busy first." Qin Feng shouted to everyone: "I'll take Song Lao and them to the cafeteria." ”

"Mr. Qin, we're not hungry."

"I'm hungry, let's talk while we eat."

Song Lao was moved in his heart.

Since it was not yet time to eat, there was no one in the cafeteria, Qin Feng ordered the canteen to fry a few hot dishes, carry a bottle of two pots, and drink while eating.

"Mr. Qin, let's come here this time, it's fate."

"Fate? What to do? ”

Qin Feng didn't think that he had anything here that Song Lao could use, he had helped build the landing gear before, and at most he would build a girder partition frame or something, but this was just to help with processing, it wasn't a fate!

Motor? I don't have one!

What else?

"Radar and avionics."

"I don't have that thing either, the Air Force's J-11 fighter is also an imitation of the relevant domestic departments, I ......" Qin Feng said this, and suddenly thought of something: "It seems that I spent 500 million last year to buy 60 sets from Grumman?" ”

Song Lao looked at Qin Feng with complicated eyes, Mr. Qin, five hundred million dollars, have you forgotten?

Looking at Qin Feng's expression, you can know that after Qin Feng bought the things back, he must have forgotten them completely!

At the beginning, Grumman Company came to pursue the matter of Oriental surveying and mapping imitation Tomcat, Qin Feng directly sent a gift of 500 million US dollars, Grumman agreed, and insisted that Dongfang's project was a double-engine strong six developed by himself, and the matter passed.

After sixty sets of spare parts for radar and avionics systems were delivered, Qin Feng asked Zhao Jiao to store them in the warehouse at the high-tech R&D base, and then ...... And the ashes fell.

The outside world is very emotional about Qin Feng's local tyrant behavior, it is good to be rich! I don't know what Mr. Qin is going to do when he buys those things back?

It is also inconvenient for Qin Feng to say that it was prepared for the failed peace model project, otherwise he would have become the prophetic emperor, and later, he himself forgot about it.

Of course, even if Song Lao didn't remind him, in a few months, after the incident, Qin Feng would definitely think of these backups, but now, he really forgot about it!

"You want this...... Is the prototype already underway? Speaking of this, Qin Feng's eyes were full of excitement: "This is too fast, isn't it?" ”

It's only the late eighties, is the J-10 going to make a prototype?

"Hurry up, if we don't speed up the progress, I'm afraid we will all be cut." Yang Gong on the side spoke, he had seen Qin Feng before, and he spoke very casually.

Chop it up?

Qin Feng was a little surprised, it shouldn't be!

"The J-11 fighter is progressing smoothly, and now even the titanium alloy wing box can be produced by itself, although there are still some parts that cannot be produced by themselves, but they can be bought from the international market, so many leaders of the Air Force are looking forward to purchasing more J-11 fighters, and would rather stop our project."

Song Lao explained: "On the other hand, the J-8 fighter sent to the United States by the north has been modified smoothly and has begun to fly test, and it is estimated that it will be able to fly all the projects in another year and a half. ”

"But it's not easy! If our J-10 wants to build a prototype, in addition to the organism and avionics, there must also be an engine, has the engine been determined? ”

"After our application, the superior leaders approved two F110 engines for us, and we will first use these two engines to assemble a prototype."

At the beginning, Qin Feng fooled the Yankees into giving him a batch of F-16 fighters, and at the same time asked for eight backup engines, but now for the J-10 project, the superiors have decided to give two of them to the J-10, which is enough luxury.

At present, only Spey is mature in China, but Spey's congenital high-altitude weakness must not be compared with the F110 This kind of three-generation push, the high-altitude and high-speed indicators of J-10 can not be reduced, F110 is obviously more suitable, but what to do with the aircraft after the two prototypes, it is still a trouble, but it is better to fly into the sky first.

"However, the funds allocated by the superiors are too small, and we don't have extra funds to purchase avionics and radar, so I hope to borrow a set of ...... from you."

When he said this, Song Lao's voice was lowered, he said that he was borrowing, but as long as he installed it, could he still dismantle it again? That's more than $8 million a set!

The batch of spare parts that Qin Feng bought back was originally prepared for the Peace Model Project, and it is suitable to modify the J-8 fighter and use it for the J-10, but it can't be given to the J-11, the radar is too small.

"Absolutely." Qin Feng was very refreshing: "Old Song, I'll write you a comment, you just find my secretary to do this!" Aren't you going to build two prototypes? I'll lend you two! ”

"No, the first prototype we built mainly tested the basic flight performance, and there was no need to wear avionics and radar, just use counterweights."

"Where is the counterweight, where the real parts are easy to use, you can use it!"

Seeing Qin Feng so generous, Song Lao's heart was full of gratitude.

In the military industrial system, many people scolded Qin Feng, because Qin Feng robbed them of their jobs, and a private enterprise robbed the jobs of their military counterparts, can those people not hate him?

However, Song Lao knew that Qin Feng had already surpassed them at the height of his standing, and while those people were making small calculations for themselves, Qin Feng was working hard for the country's industrial development!

"Mr. Qin, you are so good to us!" Yang Gong said with emotion: "You don't know, the Northern Institute is holding back a lot of energy with you, and always thinks that you look down on them. ”

Qin Feng smiled: "I don't look down on them, it won't be long before they will know my good intentions." ”

"Mr. Qin, do you have a secret?" Yang Gong reacted immediately.

"Xiao Yang, don't ask questions if you shouldn't ask."

"By the way, how is your fly-by-wire flight controller developed?" Qin Feng also changed the topic.

For J-10, the biggest problem is the fly-by-wire flight control, after all, all the aircraft currently in service in China are hydraulically operated, even the J-11 is no exception, and the flying leopard under development is not the legendary three-axis 3-degree redundant analog fly-by-wire flight controller, but the KF-1 three-axis digital stabilized flight control system.

In the research and development of the J-10, 60% of the technology is completely new, it is also the first fighter designed in full accordance with the US military standard, and it is also a non-linear canard layout of the flight control, and the flight control directly determines whether the J-10 can be successfully developed.

Qin Feng, the CEO of a private enterprise and a capitalist in many people's mouths, can support Jianshi so vigorously because he knows the great significance of Jianshi to the East, and since Qin Feng has this ability, of course he has to do a great favor. As for Jian-8, he also has to help, the Peace Model Project has been going on for so long, it can't be scrapped, right?

"We have built an iron bird platform to verify the performance ......of the flight controller in large quantities," Song Lao introduced.

Far across the ocean, Edwards Air Force Base.

It is located on the bed of Rogers Dry Lake in Murock, California, surrounded by open airspace, you can't see any tall buildings, of course, you won't feel lonely, after all, the famous big city of Los Angeles is 150 kilometers away, and at the same time, there is not only an advanced runway, but also a dry riverbed can also be forced to land at any time in case of accidents, so it has become the largest military base in the world.

During World War II, it was the training base of the U.S. Army Air Corps, and now it is not only the training base of the U.S. Air Force, but also the U.S. Air Force Flight Test Center and NASA's Dryden Flight Research Center.

Many famous aircraft flew here, including the F117, but also the F-22, the F35, and now, there are extremely ordinary-looking fighters.

The fuselage is elongated, with a pointed nose, air intake on both sides, and a tall single hanging tail, which looks like an airplane from thirty years ago.

The plane completed the test flight mission and landed at a speed of more than 300 kilometers per hour. The wheels slammed into the ground.

The wheels rubbed against the runway, making a screeching sound, and the plane slid forward for a long distance, parachuteed, and slid for another while, directly into a nearby hangar.

The pilot climbed down the gangway, and as soon as he landed, someone came up.

"James, how are you feeling?"

"The high-altitude and high-speed performance of this aircraft is very satisfying, at an altitude of 5,000 meters, it only takes 20 seconds to accelerate from Mach 0.8 to Mach 1.2, and at an altitude of 10,000 meters, it can easily fly to Mach 2.2, which is a good interceptor!"

The United States does not have a classification of interceptors, only fighters and attack aircraft, but James used the concept of interceptors, because in his eyes, this aircraft is no different from Lao Maozi's Su-15 fine-spouted bottle, which is used to intercept enemy aircraft.

Fight?

He didn't dare to use this kind of plane to move at all, because according to the flight manual he got, the maximum overload of this kind of plane was only 5.5G, which means that as long as he slid his hand a little and played a 9G overload according to the action of flying an American fighter, then his plane would disintegrate in the air in an instant.

It's no joke, God knows if this Oriental-made flight seat under his ass is reliable, and if it doesn't pop up, will he still be alive?

"How's the radar being tested?" At this moment, an eastern face below asked eagerly.

"Li Gong, of course there is no problem with the radar, after going up today, the test results are very good." James said: "I expect that within ten sorties, we will be able to carry out the interception experiment of medium-range missiles, in fact, I recommend that you directly purchase our Sparrow missiles, the performance of your self-developed missiles is too poor......

Li Ming nodded, yes, of course it would be good if you could directly purchase American-made missiles, but the problem is that American-made missiles cost money, and it will cost a lot of money!

The reason for the direct purchase of radar and other avionics equipment from the United States is that this thing can be used for a long time, and missiles are disposable, and if the East cannot produce it independently and can only purchase it, how much will it cost? The Air Force cannot afford it.

Therefore, the Air Force can only use the imported Italian seeker to install it on the body of its own production and assemble a medium-range air-to-air missile, and first solve the problem of whether it has or not, as for the performance......

Anyway, they are engaged in airplanes, not missiles, and the problems encountered in missiles are not under their control!

"There's a problem with engine two!" Just then, a ground crew spoke.

"What's wrong?" Li Ming was also anxious.

"The engine has been driven for too long, the combustion chamber has been severely ablated, and a new engine needs to be replaced!"

"This is really a big trouble, our backup engine has to be shipped from China, which will definitely delay the test flight!" Li Ming frowned.

"Then dismantle one from the first plane!" James said.

He didn't feel how complicated this was, even if the US fighter changed the engine under field conditions, that is, it only took half an hour, and as for dismantling one engine and replacing it with another, the time was the same, as long as there were two groups of technical personnel to work together.

However, when the technicians from the East began to disassemble and replace the engine, he realized that he was too naïve.

The masters began to disassemble rivets and tighten screws, and when they saw so many bolted parts, they felt that their heads were bigger.

Some must use bolts, but some are completely unnecessary, you can use quick connectors, and it is very convenient to disassemble and assemble directly, but the fighters in the East still use these ancient means.

The arrangement of internal cables and hydraulic oil pipes, which is called a messy, can be known at a simple glance on the same right hair on the two planes, which is not the same at all!

"It reminds me of the technology of the island nation." An old Grumman engineer said, "At that time, when we dismantled the Zero, we saw the same situation. Unexpectedly, more than 40 years later, the production technology of the most advanced aircraft factory in the East is actually the same. ”

At that time, the industries of the island countries were all small workshops, and the huge number of parts on the Zero War were all hand-kneaded in small workshops, so it was impossible for the Yankees to directly blow up the aircraft factory and attack the fighter production of the island country, so they used incendiary bombs to burn Tokyo.

But that was only a few decades ago, and now, the backwardness of the Eastern aircraft is showing, they are surprised.

However, more surprises are yet to come.

By the time the replacement engine was installed, the hole in one of the bolts was actually two millimeters off!

"Here, rubber hammer!" The old master shouted loudly.

Boom, boom, boom! Three hammers down, the error is one and a half millimeters!

"Wooden hammer!"

Boom, boom, boom! Error of one millimeter!

The old master was in a hurry.

"Hammer!"

Boom!

This time only a hammer was used, and the master measured it again: "Okay! ”

There is no error that cannot be solved with one hammer, and if there is, smash a few more hammers!
