"In that case, let's just produce a prototype. But is a prototype car enough? Xie Heping directly raised this issue.

Under normal circumstances, the production of prototypes is two, which is to comprehensively test the various properties of the prototype and demonstrate whether the technology is feasible. In any country, after the completion of design and theoretical research, when the demonstration model is produced, it is two.

One, most likely because of luck.

"Let's produce two, although it costs a lot more money, but if problems are found during the experiment, one will modify the design to improve the performance, and the other can continue to test. This tank is no longer a modification of the Model 59. Isn't it a little inappropriate for us to use 59 to change this project? Jiang Ming grinned when he saw that Chen Yang and the others were full of excitement on their faces.

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

Originally, they only modified it on the basis of the 59, who knew that after Liu Yijiu came up, he changed this tank beyond recognition, except that the chassis is still the chassis of the 59 tank, and all other aspects are brand new.

Power system assembly, fire control assembly, commander's sighting system, artillery commander's sighting system, armor and even composite power.

With the 1500 horsepower diesel engine provided by the Americans, it is not too difficult to produce a 780 horsepower diesel engine with this technology. It is a more complicated thing for them to design and develop for higher power power, but with lower requirements, it is not so complicated.

"The specific model name, this is not important. The prototype car will be produced first, if it can be approved by the military. Finish the test and talk about these things when the time comes. Now there are no big problems with tank guns. The problem with the automatic reloading mechanism is also not too big, and the hydraulic suspension, etc., is not strictly tested. The fire control system was also not fully effectively tested in practice. What's more, the power system is still a drawing, and the drawing design of 780 horsepower has not been completed......" Wang Shunyi said with a frown.

It is indeed a bit early to carry out the production test of the whole vehicle now.

As soon as Wang Shunyi finished saying this, everyone looked at Wang Yueshan expectantly, as long as he said that there was no problem, then there was no problem with the production of the entire prototype.

power, there has been no reliable solution.

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

The Americans will not stupidly directly give the drawings and technology that can build gas turbines and diesel engines, and set up a lot of artificial difficulties for the Chinese.

"Yes, Director Wang, it's your side now, if your power is not a problem, then this tank can be started." Liu Yijiu licked his lips and said to Wang Yueshan.

You can imagine how much pressure Wang Yueshan has under such circumstances.

He didn't speak. Instead, he looked at Tao Mingyuan, who was in charge of this work next to him.

Tao Mingyuan was originally responsible for designing the 780-horsepower diesel engine in order to match the new tank of the Republic. Because the entire engine has not made a technological breakthrough, even the theoretical design has not been completed.

You can imagine how much pressure there is.

Now there is American technology. And it is also from the advanced to the intermediate level, and he knows how many difficulties there are in the middle.

"Ladies and gentlemen, there is nothing wrong with this in itself. There's no pressure, after all, we've been working on a 780 hp diesel engine for more than a decade. However, even with the power technology of the Americans, there are not many that can be fully used in this regard. Our engine technology at the beginning. It is Soviet, and there are many differences between Sovietism and American. In addition, in order to hinder us from obtaining their technical achievements faster, the Americans have moved a lot of hands and feet on the façade of the technical drawings...... "Tao Mingyuan said with a look of embarrassment.

It's not that he doesn't want to get one out of place as soon as possible.

It's that he can't get an engine out of the way as quickly as possible.

In order to digest the drawings of the Americans, it is not possible to do it without three or two months, and then it is necessary to carry out technical demonstration, theoretical verification, and then experimental production, all of which will take at least a year.

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

At most, they have only five months from the digestion of the Americans' technology to the appearance of the finished product.

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

"It's a problem, but the living can't let their urine suffocate to death. If there is no engine, it is like human beings without a heart, no matter how strong it is, it is in vain! Liu Yijiu bit his lip and said to everyone seriously, once the engine cannot be completed on time, even if the tank is produced, there is no way to test the performance of the tank in the end.

If you can't test, how can you pass the acceptance of the state?

The equipment needed by the military is based on actual performance, not at theoretical design.

Otherwise, it would be impossible for any unit to deliver a large number of theoretical design drawings and demonstration parameters to the military, and it would be impossible to take out these drawings for production when needed.

"Shall we ask the 541 tank base and the 617 tank base, they may be able to provide us with more efficient 580 hp power, and replace it with a 580 hp diesel engine before our engines are finished?" There was no way, Tao Mingyuan could only put forward his own ideas.

780 horsepower engine, not available in the country.

China was able to produce only the 59, as well as the 59 model, which modified the 59 tank and did not make a key breakthrough in technology. 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 appearance of the Type 99 heavy tank to have the production technology of 1,000 horsepower compressed diesel engines. He couldn't wait that long, so he got a 1500-horsepower gas turbine from the Americans at the beginning, as well as a compressed diesel engine.

"With 580 hp? If so, it would be better not to produce a prototype. According to our calculations at the beginning, under the current design, 580 horsepower allows our tank to reach a maximum speed of 54 km/h, which is too far from the required 70 km/h! What's more, the ability to climb slopes, cross ditches, etc., will be reduced to a miserable speed! Jiang Ming said with an ugly face.

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

"In this case, maybe we can cooperate with the 541 tank base, Chen Gong and Mason, you are originally from the 541 tank base, you can have some communication with that side, and let them send professionals here to carry out technical research with us! When the time comes, we will share the technology with the 780 horsepower diesel engine. Liu Yijiu sighed.

After less than the thirties of the XXI century, the heart of the military industry of the republic, none of which worked.

Aero engines with the highest technical requirements and the harshest working environment, no! Therefore, the Republic can only be a light fighter until now, and the best one is only the eighth master of the second-generation aircraft, and the seventh master is equipped with the air force of the republic on a large scale, and can only watch from a distance for the high-altitude and high-speed fighters with the performance of Lao Maozi's double three (maximum speed of Mach 3 and maximum altitude of 30,000 meters). Other heavy bombers, as well as fighters, not to mention.

The overall design is complex, the working environment is harsh, and the ship gas turbine or older steam turbine with long operation time is still not good! Up to now, the Republic has not had a single large warship, and since the destruction of the Beiyang Naval Division in the First Sino-Japanese War, the Republic has no more large warships. You can't buy it, and it's even more difficult to make it yourself. The key is the engine.

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

It's a relief to think about it, after all, the republic can't even make a car engine......

Hearing Liu Yijiu say that he wanted to contact the 541 base, and let a few people take the lead, Shi Chuanxiang was the first to raise objections.

Because he is in charge of the hydraulics, not the power system.

Chen Yang shook his head even more.

541 is already a place they don't want to bring up.

"I'll get in touch with them. In any case, we all belonged to the Fifth Machine Department before. Seeing this situation, Qian Dayong shook his head, why did Liu Yijiu let Shi Chuanxiang and others contact his old club, he couldn't figure it out, but he should be responsible for this matter.

He is at the service of the whole project.

"The potter also communicates more with that side. In half a year, I want to see the engine! In half a year, our new tank has to run, we don't have much time, and if we miss this opportunity, we will lose more opportunities! Liu Yijiu was too lazy to care about this, he directly proposed that in half a year, he must see the new tank appear in its entirety.

I can't tell you that the Iran-Iraq war in the Middle East will be getting closer and closer, Iran and Iraqis will purchase tens of billions of dollars in arms, these countries with endless black soft gold under the buttocks, their own domestic military production system is not very good, but the army is quite strong!

Once the war that can bring huge profits to the military industry of the republic is missed, the military industry of the republic still has only the original path -- the conversion of military to civilian use, restructuring, bankruptcy and bankruptcy.

In particular, 541, if it can have a huge number of foreign trade purchase orders, it will not let such a huge base eventually sell to a certain department of people with a background at the price of cabbage, and become a complete private enterprise. (To be continued......)
