Qin Feng was stunned for a moment, and then shook his head firmly: "No, no, we can use it as a reference, but if you want to imitate the engine, you still have to be cautious." ”

In his eyes, the most important technology above is explosive reactive armor, we can draw a scoop according to the gourd and imitate it, even if the 99 tank needs to use a more high-grade explosion, but the 59 tank can be directly installed with imitations, and it can be driven out to pretend to be forced.

The second is to test the gun to see if our armor-piercing shells can penetrate it. According to what Makarenko said, if you put a base amount of ammunition in it, you can also use it to test the level of armor-piercing bullets used by Lao Maozi to see if your own tanks can defend against it.

As for other technologies, they need to be used selectively or discarded.

Motor?

Qin Feng has never been optimistic. He did not want his appearance to lead the development of tank technology in his homeland on the wrong path.

"Mr. Qin, isn't gas turbine the trend of tank power development? Why are you shaking your head so firmly? Director Wang asked curiously.

"Who said gas turbine power is trending?" Qin Feng looked at Director Wang with a complicated gaze: "Lao Maozi uses it, and Americans also use it, can it show that gas turbines are a trend?" I don't think that motivation is right for us at all! ”

"Why?" Zhu Lao asked.

"Because we're poor!"

Qin Feng's attitude in this aspect is very firm, and when he heard his words, the crowd suddenly became even more strange, because he was poor, he couldn't use a gas turbine?

"Mr. Qin, is the purchase price of gas turbines very high? If it is imported from abroad, the price is definitely not cheap, but if we imitate it ourselves, the price should be able to come down, right? In the past, there was no suitable gas turbine mapping and imitation, but now with Lao Maozi's tank engine, we can completely draw a scoop according to the gourd. ”

"It's not the cost, it's the cost of use." Qin Feng introduced: "Yankee's AGT1500, with a reheater, the fuel consumption rate has also reached 264 grams per kilowatt hour, Lao Maozi's GTD1250, without a reheater, the fuel consumption rate is as high as 306 grams per kilowatt hour, let's look at the diesel engine, the fuel consumption rate of Germany's most advanced Leopard 2 diesel engine is only 245 grams per kilowatt hour." ”

Measuring the fuel consumption of the tank, not how many liters per 100 kilometers, this is not accurate, for example, the maximum range of the Leopard 2 tank is 550 kilometers, which sounds very good, but this is running out on the road, just like the cruising range of electric vehicles, the false standard is serious. In fact, when the Leopard 2 tank is off-road, it can only run 161 kilometers on a tank of fuel.

Aside from the road conditions to talk about fuel consumption, that is, hooligans, highway and urban stop-and-go, it is possible to double the difference in fuel consumption, and then to the off-road, fuel consumption can differ by three or four times, the same engine speed, the use of different gears, of course, the distance is not the same.

Therefore, the most important parameter for a tank is the fuel consumption per kilowatt hour of energy output, which is constant and can be used to compare with each other.

"If you look at the data, the United States is not much higher than the German engine fuel consumption, but you have to know another thing, the maximum speed of the diesel engine is only more than 2,000 rpm, the lower the speed, the less fuel consumption, at idle, the diesel engine fuel consumption is only a quarter or even a fifth of the full speed, but for gas turbines, the fuel consumption at idle speed and full speed is almost the same!"

This is the key to the fuel consumption of gas turbines.

Many people drive and want to idle the whole time, why? It's not because the idling speed is the most fuel-efficient, the accelerator pedal under the feet are reluctant to step on it, and it feels like a sin to rise to two thousand rpm.

What about gas turbines? The gas turbine has more than 30,000 revolutions when it is running at full speed, and it has to be thousands of revolutions when idling.

It is a troublesome thing to not save fuel when idling, after all, the tank unit is not always maneuvering, and may also be on standby, and Lao Maozi has had this sad experience: all the fuel is burned in the idle speed!

"The same 1500 hp engine, 1200 liters for the Leopard 2 tank, 1900 liters for the American M1 tank, so that almost the same endurance is achieved, guys, can our country withstand this kind of consumption? What's more, gas turbines still burn aviation kerosene. ”

Many tank engines are multi-fuel, and Lao Maozi's T72 tank can burn diesel, kerosene, gasoline, and even a mixture of these oils.

There are many types of gas turbines that can be burned, but this is only theoretical, and later generations of Lao Maozi came to the East for exercises, and the army responsible for receiving them was not clear, and only prepared diesel, and Lao Maozi refused to add it alive or dead, so he asked for aviation kerosene.

Although the gas turbine can burn any oil, it is a big project to clean the entire oil circuit before burning!

The most suitable fuel for gas turbines is aviation kerosene, after all, gas turbines evolved from aero engines, which caused another problem: not to mention the price, which ground forces in the army, in addition to the army aviation, will have aviation kerosene?

On the battlefield, it will be very difficult to resupply fuel, and it will be even more troublesome to resupply one more model!

A tank unit, there are tanks, there are armored vehicles, there are trucks, the back burns diesel, only the tanks burn aviation fuel, under tension, will it be filled with the wrong fuel?

There's a lot of problems with that.

"Yes, when we tested the ST6J-771 gas turbine, we had noticed this problem, in addition to the volume of the air filter is very large, fuel consumption is also a big problem, we thought that this gas turbine technology was backward, but I didn't expect the advanced gas turbine to be like this, Mr. Qin is really powerful, these specific data can be known clearly." Zhu Lao sighed.

It is not that the country has not been exposed to gas turbines, in the seventies, the country has noticed the advantages of gas turbines, although there is no domestic, but it can be purchased from the West, in February 78, the imported gas turbine was stuffed into the engine compartment of a Type 69 medium tank, after experiments, the superiority of the gas turbine was proved: good maneuverability, easy to start in cold areas, but fuel consumption is indeed high.

At that time, I thought that with the development of technology, fuel consumption could be reduced, but now Qin Feng introduced it like this, only to know that it is not easy to save fuel, and even if fuel consumption is reduced, it is impossible to change the disadvantages of idle speed and full-speed fuel consumption.

They don't know the fuel consumption data of the advanced M1 tank and Lao Maozi's T80 tank, but Qin always knows!

Qin Feng smiled: "The last time I went to the United States, I became friends with the designer of the M1 tank, this time I went to Lao Maozi, and I came into contact with the T80 again. ”

Getting it back for testing is the last link, and there will definitely be various tests before that. As for why he knew this, of course, it was his Qin Feng's friends all over the world.

"Friends with the designers of the M1 tank? Mr. Qin, you are really powerful enough! Director Wang was very impressed: "It would be nice if I had the opportunity to invite him to our institute for an exchange." ”

"It shouldn't be that hard, but are you sure?" Qin Feng said: "The route taken by the American tanks is not necessarily the right way, and it may lead us into the ditch." ”

"Then we'll keep our eyes open." Zhu Lao said.

After the vignette, everyone continued to talk about the technology of the T-80 tank.

"When we get this tank, we can also study the automatic loader technology above, at present, the only automatic loader we can access is the two-layer turntable type of the T-72, and the T-64 and T-80 of Lao Maozi use vertical discs, and it is said that the loading speed is faster." Zhu Lao continued to speak.

The T-64 has cross-era significance in Lao Maozi's equipment sequence, with advanced composite armor, high-horsepower engine, 125mm tank gun, and automatic loader.

In order to minimize the frontal projection area, Lao Maozi's tanks are very short, and the tankers are all short people from Central Asia, even so, the interior is very crowded, and the physical fitness of the short people is also seriously insufficient, so when the caliber of the tank gun is increased to 125 mm, it is already a very difficult task for the loader, and it is more convenient to get on the automatic loader.

The design indicators of the T-64 are high, and the loading index of ammunition requires 9 rounds per minute! This means that it takes six or seven seconds to reload. Twice as fast as manual reloading.

This automatic loader stumped the people of the Morozov Design Bureau for a long time, and they racked their brains to come up with an L-shaped automatic loader, with the cartridge placed vertically, and the warhead placed horizontally, as if kneeling there, and when the ammunition was lifted, this right-angle bend would gradually flatten, and when it reached the tail of the gun, it would be coaxial with the gun, and then it would be pushed forward.

It is because of this design that the failure rate of this automatic loader is very high, after the first batch of T64 equipment troops, the tankers complained bitterly, because the automatic loader is unreliable, they often need to reload manually, and the gun commander has to work part-time loader, which is not as good as before.

With the development of the T-80, the automatic loader is still of this structure, but it is said that the reliability has improved a lot.

Because of the failure rate of the T-64, Lao Maozi decided to let Nizhny Tagil design a simplified version of the tank, the requirement is to improve reliability, even if the rate of fire is reduced, there is no problem, Kartsev pondered, felt that if you want to make the automatic loader more reliable, you have to change the structure.

As a result, the automatic loader on the T-72 tank was changed to a horizontal disc loader, both the warhead and the projectile cartridge were placed horizontally on the disc, and the upper and lower layers were lifted together when needed, and then the bullet bar was pushed twice to push the warhead and the cartridge forward.

Because of the two pushes, the rate of fire is reduced to eight rounds per minute, of course, this is the theoretical rate of fire, in fact, it is good to reach six rounds per minute, although the rate of fire is reduced, but the reliability is greatly improved, after all, the warhead and propellant have always been translational, do not need to rotate, reducing the occurrence of failures.

Now, the country already has the T-72 tank as a reference, and the automatic loader above is being copied, but since the T-80 is about to be owned, of course, it is also necessary to refer to the above technology.

What is this Qin Feng's attitude? Can he object?

"Okay, when the tank arrives, we can test it and see which loader is better for us." Qin Feng said: "Of course, the rate of fire is not the most important indicator, and reliability should be put in the first place." ”

There is not much point in pursuing the maximum rate of fire, it really can't be fought so fast on the battlefield, the tank gun can be ready, and the gun commander can't aim continuously and quickly, Lao Maozi designed such a high index, when considering the use of the rolling armor torrent to bulldoze the whole of Europe, the opposite side is also a huge armor cluster, and the tank that rushes in front does not survive for a minute, and it is necessary to dump the most shells in the shortest time.

In fact, such a scenario has never appeared and will not appear in the future, and reliability is the most important thing for tank troops.

"That's right, reliability is the most important thing." Zhu Lao nodded.

"By the way, if you're lucky, there should be old Maozi's own ammunition on it, if there is, we can also test the performance of their armor-piercing shells, this time we got a total of two, wait until all the tests are over, remove one of the engines, etc., and leave a tank empty shell, we can also have a wreck test."

The crowd was excited again.

Just now I just thought about using the various technologies above, but I didn't think about using them to test the gun! In fact, the test gun is the most important thing.

When there was a conflict in the north, the army managed to get a T-62, so they greeted them with various weapons, and finally found that no weapon could destroy the armor of this tank!

Not then, but now? Will it still not be able to do so now?

It is necessary to pull all kinds of domestic anti-tank weapons over and test whether it is possible to penetrate them on Lao Maozi's most advanced tank, and at the same time, it is necessary to test them with Lao Maozi's artillery to see how high the penetration depth is.

"Mr. Qin, what method did you use to get out the tanks in Lao Maozi's army?" The big guy sighed again.

Qin Feng smiled: "Everyone, we are all talking on paper now, in fact, I came here to tell the big guy that there are two tanks that are drifting across the ocean, and our relevant departments have to coordinate to get this kind of tank back from abroad, and I can only transport it to Africa." ”

"It's easy to say, of course we'll coordinate." Zhu Lao said: "Mr. Qin, when will these two tanks arrive in Africa?" Can I go over and pick up the tank? ”

Zhu Lao's eyes were full of anticipation.

This is Lao Maozi's most advanced tank! Since Zhu Lao heard the news, he has been impatient, he can't wait to be able to touch the hull, barrel, and engine of the tank with his own hands immediately, and he can't wait to disassemble this tank immediately.

Qin Feng looked at Zhu Lao's empty sleeve: "Zhu Lao, the conditions in Africa are not very good, especially if you are still fighting, you are the most important scientific researcher in the field of military industry, so don't risk yourself." You have to have three longs and two shorts, and I can't afford to take responsibility. ”

Qin Feng really can't afford to be responsible, Zhu Lao is the chief engineer of the third generation of tanks, and he belongs to the treasure-level military research and development personnel, if something happens to him, Qin Feng will have to mix with the black uncles in his life.

Zhu Lao smiled: "I'm just an ordinary person, but I still won't trouble you, let's report to the superiors and let the superiors send someone over." ”

When Santana left Huaishuling, it was already dark, and there were more people on the road, Zhao Jiao drove the car and slowly moved forward in the traffic.

"By the way, I'll have to contact Imai Castle tomorrow and ask him to send a batch of Nintendo's game consoles." Qin Feng thought of something and instructed Zhao Jiao.

With Zhou Zhiyuan's help, all kinds of light industrial products have been gathered, instant noodles are ready-made, and there are game consoles left, which has to be taken from Imai City.

"Okay."

"Also, the TV and the cassette recorder have to keep up, and the contract I negotiated with the Arctic Ocean Company is to use electrical appliances to offset the bill."

"Okay."

"Gillian, you seem to have something on your mind?"

"Brother Feng, when you go in the end, you didn't say what we wanted, you promised Brother Mulatu, when their country is established, they will officially establish diplomatic relations, this is a big deal!" What Zhao Jiao is worried about is this matter, Qin Feng has made such a great contribution to the country, he has to let his superiors agree to his request.

Qin Feng smiled: "Gillian, don't worry about this, it's definitely no problem, let's make meritorious service first, and then make requirements, so as to win the recognition of the leader, if you come up and put forward various requirements, the leader will think that we have something else to ask for, by the way, turn left at the intersection in front, let's go back to the motorcycle factory." ”

"Okay."

Of course, Qin Feng is most worried about the motorcycle factory, after all, the shoe factory and the instant noodle factory are all petty fights, and the war readiness warehouse is also on the right track, and they are the most reliable people, only this motorcycle factory, starting from scratch, has a large group of workers, and has all kinds of production equipment, which has all kinds of potential problems and risks.

I went out on my own, and I tossed back and forth for a week, how was it over there?

"Is there any trouble with the motorcycle factory lately?"

"Yes, the qualifications I applied to my superiors have not been able to come down..."

Santana drove into the Pingwang Motorcycle Factory, stopped at the door of the workshop and turned off the engine, Qin Feng opened the car door, planning to walk over to take a look, compared with when he left, there were already a lot of machinery and equipment inside, it seems that the engine production line eliminated by FAW has been moved over!

With the engine production line, it is possible to produce vertical gasoline engines and single-cylinder diesel engines, and with engines, motorcycles and tractors are available!

Qin Feng's heart was full of anticipation, and he just wanted to walk in, but he saw a figure sneakily coming out of it, looking around, and then slipped into the corner and unbuttoned his pants...

Qin Feng's face suddenly darkened, he returned to the car, picked up the camera, no matter who this guy is, and no matter what job this guy does in the factory, in short, deal with it first!

At this moment, a puddle of water had appeared in front of the figure, and just as he was whistling freely, suddenly, click!

The flash came on.

The man turned his head in surprise.

Click!

It's the camera's flash again.
