"Boom!" Before the sound of the cannon being discharged, everyone had already seen the huge turret vibrate violently behind it, and the whole body shook a little, and the four-meter-square target position marked with the huge Arabic numeral 9 in the distance quickly splashed dirt.

After firing this shot, the No. 1 tank did not stop, because Liu Yijiu had already ordered them to hit the No. 2 target, which had to make the entire turret rotate 180 degrees, the nose of the tank was still driving forward, and the turret was directly turned, and the second shell was fired while climbing the slope.

"Car two, what's going on?" Liu Yijiu didn't bother to call it a hole, the No. 1 car had already fired two shells, and the No. 2 car had not moved until now, since climbing the steep slope, it had stopped at the top, and the turret had not even turned.

Could something have gone wrong?

It's normal to have problems, but the people in the cockpit of the tank should report it!

Liu Yijiu regretted that he directly let these soldiers conduct the test from the beginning, and the technicians should conduct a part of the test before letting them participate, even if the physical strength of the technicians does not allow them to test for a long time, it is much better than these problems.

"Report, car No. 2 has a hydraulic failure!" A report came from the walkie-talkie, which complicated the expressions on the faces of the people who were paying attention to the situation around them.

The tanks all use a torsion bar suspension system, and Liu Yijiu has to use a hydraulic suspension system on the Longwei, and at the same time, he also uses hydraulic reloading and hydraulic gun stabilization technology. These are relatively simple to operate, but reliability is often not as convincing as mechanically.

"Doesn't a hydraulic failure translate into a mechanical operation of a torsion bar? What did you do during your training? Liu Yijiu was immediately furious, and made such a moth for himself at this time.

Didn't you see Li Yuming's old thing at the 617 base, who has always been looking for trouble while watching the excitement! To get orders from the military. This old thing will definitely stop it with all its might, if there is some other irreversible problem. can still bear it, the hydraulic system is personally instructed by him. In order to improve the battlefield survivability of the Lunbo tank, this uses two operating systems, hydraulic pressure and torsion lever, and they are independent of each other and do not affect each other.

These two operating systems alone have increased the cost of the tank a lot.

"Xiao Liu, what's going on?" Long Yaohua frowned and asked, these tanks performed very well at the beginning, and he now gave great hope to this.

"During the experiment, it's normal for things to go wrong. Since there has been a malfunction, and the other one continues to be tested, it is better to let this one be withdrawn first, and then continue to test after the fault is solved. Li Yunlong took a deep breath and said with a frown.

Qian Dayong looked at Jiang Ming beside him with a worried face, while Jiang Ming looked at Liu Yijiu with a frown.

"You don't have to stop testing, just let them continue experimenting." Liu Yijiu said with great certainty.

"Isn't it a glitch?"

"It's just that one of the operating systems failed, in order to increase the battlefield survivability of our tanks, before the design. We took these problems into account and used two operating systems, hydraulic pressure and torsion bar, but now only the hydraulic system has failed, and there is also a torsion bar system......" Liu Yijiu said very plainly.

"Is there a difference between the two?" Li Yunlong asked with a frown. He really didn't know about hydraulics or anything.

It sounds a bit high-tech, but it's high-tech.

"For people who don't understand technology, people who don't do it. There is also no difference between the two maneuvering systems. Liu Yijiu didn't bother to explain, Li Yunlong knew that these things were useless. For the bigwigs of the military, as long as the technology is reliable. The cost of production is not too high for the entire military to bear.

What do they do with such detailed technology?

Everything is done by professionals, big guy, just need to make the final decision with an idea.

While the people were talking, the driver of car No. 2 had already begun to switch the operating system to torsion bar operation. This purely mechanical way of handling is very cumbersome for the driver and does not have much flexibility. The whole world knows this.

The hydraulic system is used to assist the operation and reduce the difficulty of operation.

Liu Yijiu thought that the Republic would eventually invest a lot of effort in research, so he simply came up with such a solution from the beginning, so as to avoid wasting too much money, and also let other units have some references in scientific and technological research, get inspiration from the side, and get effective solutions when designing other weapons and equipment.

While several people were talking, the turret of the No. 2 car began to rotate slowly, and then aimed at the target in the distance, and a cannon sounded, and soon the sound of explosion was heard again......

Test, continue.

Regarding the performance of these tanks, Li Yuming's face became even more gloomy.

On the new tank project, they were actually left far behind by a unit like the Ninth Academy, which was just a technical backup.

Not to mention anything else, just the performance shown along the way made him shake his head and sigh that they were too much worse than the Ninth Academy.

At noon, everyone ate in the army canteen on this side of the test site, where a company of the garrison battalion was stationed, mainly the mechanized unit test company, and the heavy artillery and firearms test site, which had not yet been completely completed.

In the afternoon, we continued to test the performance of various maneuvers, and some small problems appeared, Li Yunlong, Long Yaohua and Liu Qingshan and other bigwigs were arranged by Liu Yijiu to experience the No. 1 car, and under their personal operation, they found the difference between the hydraulic system and the mechanical system, and then the chief designer Jiang Ming introduced these technologies to them.

"I really didn't expect that we could produce such an advanced tank in China, if we can make the tonnage heavier and the tank more huge, it can become the world's first-class tank!" Coming out of the tank, Long Yaohua said with great emotion.

He didn't ask where the technology came from. They are all clear about the transactions between the Ninth Academy and the US military. There is some technology, but it definitely won't include some of the electronics in it. There's even a computer-aided operating system inside this tank!

For them, this is definitely a high-tech weaponry.

"It's really very good, if the final test is completed, I think we can equip at least one armored division......" Li Yunlong also didn't expect that he would be able to feel the advanced of this tank when he entered it, and the previous tanks, they also got into the cab to experience the feeling. It's just that, Xiao Liu, even the air conditioner or something is installed here. The chair is so soft, isn't it a bit too wasteful? If you get rid of that, the cost will be much less! ”

Regarding the installation of air conditioning in the tank, Li Yunlong was very dissatisfied.

This is to increase the production cost and operating cost of the tank, and there are more electrical appliances, which requires more fuel consumption......

"Air conditioning is a must. The two cars are about to be put into the extreme desert environment test, and after completion, they will go to the northeast to conduct the extreme cold environment test, and these environments will be tested if there is no air conditioning. Fighters operating tanks will be affected by these extraordinary environments, and if it is in a war, this will reduce the combat range of tanks, but our country has a territory of 9.6 million square kilometers. The environment is very different......" Liu Yijiu shook his head.

The Republic inherited Lao Maozi's Soviet weapon style, everything was for practicality, and it would not consider humanized design at all.

After all, this is the age. Few countries have studied how much operator comfort can improve the performance of weapons and equipment.

A lot of weapons and equipment in the Soviet Union are because they are very cumbersome to operate. That's why it will eventually decline. LIKE THE TU-22 BACKFIRE STRATEGIC BOMBER, NOT MANY OF THEIR PILOTS ARE WILLING TO FLY IT. It's just too difficult to operate.

This is not because of cost, but because of technology.

Even the Americans, the current use of hydraulic technology is not very ideal. True hydraulics need to be combined with electronic control technology to achieve the most ideal state.

"Lao Li, what kind of feelings do you have? Can our tank design still be in your old eyes? Seeing Li Yuming coming out of the tank with a shocked face, Qian Dayong asked relentlessly.

Liu Yijiu saw him doing this, and he didn't stop him.

"What's the big deal? Anyway, this is just a medium tank with five pairs of load-bearing wheels. The whole world knows that the most advanced tank must be a heavy tank, and when you make a more advanced heavy tank than us, I will personally apologize to you! Li Yuming has already made a decision in his heart, and after going back this time, he will have to revise their current design plan.

It's also a medium tank, and the gap is too big.

The Longwei type, even the computer-aided operating system is available, and they are still working on the second-generation tanks that have fallen behind, and now their design scheme is very close to the third-generation tank, but it is definitely not the third-generation tank, which is all thanks to the T72 and T64 tanks obtained by the state.

Even so, they have a lot of technology that they haven't conquered.

Not to mention anything else, even the automatic reloading mechanism has not been studied clearly, large-caliber running, composite armor and Chobham armor are still being studied.

He didn't know that the reactive armor on the outside of the Lunwei tank had not yet been installed, and the anti-aircraft missile launchers and anti-armor missile launchers on the turret had not yet been installed. Otherwise, he wouldn't have said such a thing.

"This old thing, it's shameless. His own face was beaten so loudly, and he still felt that they were the most awesome! Chen Shuhao sighed and shook his head helplessly. (To be continued......)

PS: I saw a brother who said that the gourd went home and updated a change, and the gourd really didn't know where you saw that there was only one change a day. At least there are two more gourds every day.

In addition, during this time, many times I was getting the procedures for the second child, and my wife was still waiting in my hometown for the gourd to finish this side and then go back to do it there! Hulu also hopes to write more, after all, the more updates, the more Hulu can get more manuscript fees. I just hope that the brothers can understand the gourd.
