"Since that's the case, then just produce a prototype car. But is a prototype car enough?" Xie Heping directly raised this question.

Generally speaking, the production of prototypes is two. This is to comprehensively detect the various performances of the prototypes and to demonstrate whether the technology is feasible. After completing the design and theoretical research, there are two cars when producing and demonstrating the model.

One, it is very likely that it is due to luck.

"It's better to produce two vehicles. Although it costs a lot of money, if problems are found during the experiment, one will modify the design and improve the performance, and the other will continue to be tested. This tank is no longer an improved model of the 59 model. Isn't it a bit inappropriate for our project to use 59 to modify it?" Jiang Ming saw the excitement on Chen Yang and others' faces and grinned.

It was proposed to change the name of the entire project.

Originally, they just made modifications based on 59, but who knew that after Liu Yijiu came up, he changed this tank beyond recognition. Except for the chassis that still uses the chassis of the 59 tank, all other aspects are brand new.

Power system assembly, fire control assembly, vehicle commander sighting system, gunnery commander sighting system, armor and even composite power.

With the 1500-horsepower diesel engine provided by Americans, it is not too difficult to use this technology to produce a 780-horsepower diesel engine. It is a relatively complicated thing for them to design and develop higher power, but it is not that complicated to reduce the requirements.

"The specific model name is not important. First produce the prototype. If it can be approved by the military and completed the test, we will discuss these things. Now there is no big problem with tank guns, the problem of automatic loading mechanism is not too big. The hydraulic suspension and other aspects have not been strictly tested, and the fire control system has not been fully and effectively tested. More importantly, the power system is still a drawing, and the 780 horsepower drawing design has not been completed..." Wang Shunyi said with a frown.

It is indeed a bit early to conduct the production test of the whole vehicle.

As soon as Wang Shunyi finished speaking, everyone looked at Wang Yueshan with anticipation. As long as he said there was no problem, there would be no problem in the production of the entire prototype.

There has never been a reliable solution for power.

From the beginning, Liu Yijiu was counting on obtaining the power system from the Americans. Now they have obtained a 1,500-horsepower compressed diesel engine in the hands of the Americans and a 1,500-horsepower gas turbine for aviation conversion to land, but this is just the most primitive technical drawings.

Americans will not foolishly directly give drawings and technologies that can build gas turbines and diesel engines. They have set a lot of artificial difficulties for the Chinese.

"Yes, Director Wang, it's your side now. If your power is not a problem, then the tank can start to move." Liu Yijiu licked his lips and said to Wang Yueshan.

It is easy to imagine how much pressure Wang Yueshan is under such circumstances.

He didn't say anything. Instead, he looked at Tao Mingyuan who was responsible for this work.

Tao Mingyuan was originally responsible for designing a 780-horsepower diesel engine. In order to match the Republic's new tanks, the entire engine has not been completed because it has not made technical breakthroughs, and even theoretical design has not been completed.

It is conceivable how much pressure is.

Now that Americans have the skills, they are still developing from advanced to intermediate level, he only knows how many difficulties there are.

"Dear leaders, there is no problem and no pressure in this regard. After all, we have invested more than ten years in the 780-horsepower diesel engine. However, even with American power technology, there are not many things that can be used completely. Our engine technology at the beginning was from the Soviet system, and there are many differences between the Soviet system and the American system. In addition, in order to prevent us from obtaining their technical achievements faster and digesting and applying them, Americans have moved a lot of hands and feet on the facade of the technical drawings..." Tao Mingyuan said with embarrassment.

It’s not that he doesn’t want to get one as soon as possible to have an engine.

But he couldn't get out an engine as soon as possible.

To digest American drawings, it is not enough to take three or two months. Then technical demonstration and theoretical verification are required to carry out experimental production. All of this requires at least more than one year.

According to the current situation, Liu Yijiu proposed to realize production as soon as possible and start production of prototypes in advance, and it is impossible to give him more than a year.

At most, from digesting American technology to the emergence of finished products, they only have five months.

This is the time that Tao Mingyuan guessed in his heart, and the actual situation may be shorter!

"This is a problem, but living people cannot suffocate their urine to death. Without an engine, it is like a human without a heart. No matter how powerful it is, it will be useless!" Liu Yijiu bit his lip and said to everyone seriously. Once the engine cannot be completed on time, even if the tank is produced, it will not be able to detect the tank's performance in the end.

If you cannot test it, how can you pass the national acceptance?

The equipment needed by the military depends on actual performance, not on theoretical design performance.

Otherwise, any unit will deliver a lot of theoretical design drawings and argumentation parameters to the military. It is simply impossible to take out these drawings to produce when needed.

"Do we ask the 541 Tank Base and the 617 Tank Base, they may be able to provide us with a more efficient 580 horsepower power, and before our engine is completed, we should use a 580 horsepower diesel engine instead?" There was no way, Tao Mingyuan could only come up with his own ideas.

780 horsepower engine, not available in China.

China can produce only 59, and the 69 model that has not made a key breakthrough in technology in China. All this is because the power system is not good.

Liu Yijiu deeply understood that for a long time, the Republic seemed to have to wait until the 99 heavy tank appeared before it had the production technology of 1,000 horsepower compressed diesel engines. He couldn't wait that long, so he got a 1,500 horsepower gas turbine and compressed diesel engine from the hands of Americans at the beginning.

"It uses 580 horsepower? If this is the case, it would be better not to produce a prototype car. According to our calculations at the beginning, under the current design plan, 580 horsepower can reach a maximum of 54 kilometers of our tank, which is too far from the required 70 kilometers! What's more, the ability to climb hills, cross ditches, etc. will be reduced to a terrible speed!" Jiang Ming said with an ugly face.

If they could use 580 horsepower, would they be so confused?

"Since that's the case, maybe we can cooperate with the 541 Tank Base. Mr. Chen and the stone engineer, you are originally from the 541 Tank Base. You can communicate with them and ask them to send professionals here to work with us on technical research! At that time, we will share the technology with them for the 780-horsepower diesel engine." Liu Yijiu sighed.

Less than 1930s, the heart of the Republic's military industry was not feasible.

The aircraft engine with the highest technical requirements and the harshest working environment cannot do it! Therefore, the Republic has only been light fighter jets so far, and the most powerful one is the Baye, who has a second-generation aircraft, and the Qiye, who has equipped the Republic's air force on a large scale. For the Russian twin-three performance (mach 3 maximum speed and maximum ceiling of 30,000 meters), he can only watch from a distance. Not to mention other heavy bombers and fighters.

The overall design is complex, the working environment is harsh, and the requirements are continuous, reliable and stable. The long-running ship gas turbine or older steam turbines are still not possible! Until now, the Republic has not had a large warship. Since the Beiyang Navy was wiped out in the Sino-Japanese War of 1894-1895, the Republic has never had a large warship. It is even more difficult to buy it, and it is even more difficult to make it by itself. The key is the engine.

And now, even the right heart of a tank is a problem!

Think about it, I feel relieved. After all, the Republic cannot even manufacture automobile engines...

When he heard that Liu Yijiu said he wanted to contact the 541 base and let him take the lead, Shi Chuanxiang was the first to raise an objection.

Because he is responsible for the hydraulic system, not the power system.

Chen Yang shook his head even more.

541 is already a place they are unwilling to mention.

"I'll just contact the other side. No matter what, we were all affiliated with the Fifth Machinery Department before." Qian Dayong shook his head when he saw this situation. He couldn't understand why Liu Yijiu asked Shi Chuanxiang and others to contact his old boss, but he should be responsible for this matter as the dispatcher.

He serves the entire project.

"The potters also communicate with the other side more. In half a year, I want to see the engine! In half a year, our new tank must run, we don't have much time. Once we miss this opportunity, we will lose more opportunities!" Liu Yijiu was too lazy to care about these things, so he directly suggested that in half a year, we must see the new tank appear intact.

I can't tell you that the Iran-Iraq War in the Middle East will get closer and closer. Iran and Iraqis will purchase tens of billions of dollars of arms. These countries with endless black soft gold under their butts have their own domestic military production system, but their military construction is quite strong!

Once the war that could bring huge profits to the Republic's military industry was missed, the Republic's military industry still had only the original route, military transformation, reform, and bankruptcy.

Especially 541, if it can have a huge number of foreign trade purchase orders, it will not be possible that such a huge base will eventually be sold to people with backgrounds in a certain department at the price of cabbage, and become a completely private enterprise. (To be continued.)
