Wang Xuexin directly answered: "Increase the range of 'high fire'!"

Professor Su said doubtfully: "Battal Commander, it is indeed possible to increase the range of the 'High Fire'. We can solve this problem by improving the propellant and increasing the number of rocket engines, but... will the Japanese still be fooled?"

Professor Su's last sentence, "Will the Japanese be fooled again?" was a bit inexplicable.

However, Wang Xuexin could understand it. Professor Su thought that Wang Xuexin still planned to launch the "high fire" into the air for the Japanese to intercept, and then blow it up in pieces.

Wang Xuexin replied: "The Japanese will not be fooled, and of course they will not intercept it!"

"Then what are you..." At this point, Professor Su was a little confused. After thinking about it, Professor Su asked again: "Then the battalion commander increased the range to attack the Japanese heavy artillery?"

Then he explained to himself: "This is not right. The current range of the 'high fire' is enough to fight the Japanese heavy artillery. What's more, our aviation team still has the advantage and has air superiority. I'm afraid the Japanese heavy artillery will never dare to do it again."

Bombing Yuncheng!"

Professor Su still has some military knowledge.

This is one of the reasons why Professor Su and He Zhimin can become the leaders of the R&D team.

In addition to having knowledge of physics and machinery, Professor Su also knows some military theories because he has always been concerned about domestic military and war situations.

In addition to his expertise in aircraft manufacturing, He Zhimin is also good at mathematical calculations and analysis.

The combination of these two people and their mutual understanding can be regarded as a good connection for military manufacturing.

For example, at this time, He Zhimin couldn't understand what Wang Xuexin and Professor Su were saying:

The discussion is obviously about the range of "high fire", why do you say "Japanese will not be fooled"? Is there any relationship between the two?

Why is the current range of "High Fire" enough to defeat Japanese heavy artillery? Isn't the longer the range better?

Why didn't the Japanese heavy artillery dare to bomb Yuncheng even though the Eighth Route Army had limited air supremacy? Wouldn't the Japanese send planes to protect the heavy artillery?

As long as there is any doubt or lack of understanding in this, it will be difficult to follow this idea to form a complete logical chain, so it will be like listening to a book from heaven.

But this is not a problem. As long as Professor Su understands it, I will spend some time explaining it to He Zhimin after the meeting.

Wang Xuexin did not answer but asked instead: "Mr. Su, if you just improve the propellant to increase the combustion value, or increase the number of rocket engines, how much can the range be increased?"

Professor Su was stunned for a moment, thought for a moment and then replied: "I don't know the details yet, but... it should be possible to increase it by twenty kilometers, right?"

As he spoke, Professor Su turned his attention to He Zhimin, who was good at this aspect.

He Zhimin did a mental calculation for a while, then nodded and said: "It's almost the same, because the number of rocket engines cannot be increased without limit. After the increase, its own weight will also consume energy, and the wind resistance will also increase!"

"Add twenty kilometers!" Wang Xuexin said: "This is far from our army's combat requirements!"

Professor Su was secretly surprised when he heard the word "far from each other" and asked with a little hesitation: "Batalion Commander, what are our army's combat requirements?"

"At least 200 kilometers!"

Professor Su and He Zhimin gasped when they heard this number and were speechless.

After a while, He Zhimin said: "Batalion Commander, you are making things difficult for us. 200 kilometers is not a small amount. You can fly from here to Xi'an."

"Battal Commander!" Professor Su said earnestly: "You have to eat one bite at a time, and you have to walk step by step. Our 'High Fire' can have a range of fifty kilometers. If it can be improved to a range of seventy kilometers, it will be already

This is quite an achievement. We can increase the range bit by bit, first to 70 kilometers, and then to 100 kilometers... This step will require 200 kilometers. Isn't this step too fast?

?”

He Zhimin then added: "And it is difficult to achieve. As mentioned just now, whether it is improving the propellant or increasing the number of engines, the range cannot be increased to 200 kilometers..."

"What if we change the engine?" Wang Xuexin interrupted He Zhimin.

"It is indeed possible to change to a more efficient engine!" He Zhimin replied: "But except for rocket engines, we do not have any technology to produce engines..."

This is true. The industry of the Eighth Route Army at this time was just in its infancy, and it was mainly concentrated in civilian industry. The military industry was all about producing guns and ammunition. With the current conditions, developing engines... it was a no-brainer.

Wang Xuexin didn't explain much. He just took the satchel from his waist and took out a stack of documents and handed it over, saying: "This is the engine technology bought from Yingjiang. They think this engine is too simple and rough, and it is difficult to use."

It is very dangerous and has many shortcomings. They planned to abandon it, so I bought its technology!"

What Wang Xuexin said is half true and half false.

The first half is fake.

This technology does not come from Eagle Sauce but from the system. To be precise, it comes from Hans, which is the jet pulse engine used by the V1 missile.

The second half is true.

This engine is indeed simple, rough, and dangerous. In addition, it has many shortcomings that are difficult to improve, such as difficult maintenance, can only work at lower altitudes, and the air inlet valve will soon be worn and penetrated, etc.

This kind of engine is obviously not suitable for use in aircraft.

Because aircraft have to be used over and over again for takeoffs, landings, high-intensity operations, etc., using this kind of engine is simply suicide.

But the v1 missile... this thing is a disposable thing. After being fired, regardless of whether it hits the target or not, it will be blown to pieces together with the engine.

So, are there still such high requirements for engine quality?

Do you still need to calculate its lifespan?

Do you still need to consider its repair and maintenance issues?

Even the disadvantage that it can only operate at low altitudes is not a problem, because the v1 missile is not required to fly at high altitudes.

He Zhimin didn't take it seriously at first.

This is not to say that He Zhimin does not believe in this engine, but he believes that even if it has the technology of this engine, it will be difficult for the Eighth Route Army to produce it.

If it weren't for the information Wang Xuexin gave him, he wouldn't even bother to read it.

However, after He Zhimin turned a few pages, he became more and more frightened... The working principle of this thing is almost the same as that of a car engine: the inhaled air is mixed with fuel in the combustion chamber and ignited by the spark plug, and then the jet airflow generates thrust.

, and then repeat this action.

It can be said that it is almost a small stove.

If the Eighth Route Army were to produce...it might also have difficulties.
