Happiness comes so quickly, and so does trouble.

Major General Konrad Adenauer and a large group of experts who came with him tested the tractor, and while rejoicing, his brow could not help but furrow.

He Zuguang presided over the research of the crawler tractor is currently only an experimental prototype state, but fully proved the mechanical feasibility, crawler, pilot wheel, load wheel, girder, shock absorber of the overall layout is also good, can be called a creative new design, which is gratifying.

But there are also a lot of problems, first of all, the 2.0 powered diesel engine is too small, which leads to a series of problems.

This light tracked tractor is indeed capable of carrying weight, but the carrying capacity is very limited, at most a thin iron shell, plus a heavy machine gun and a two-gun group, such weight is almost the limit.

Due to the original design, the space of the tracked tractor was very small, and the heavy machine gun crew had to sit on the engine to fight, which required the addition of a compartment and the redesign of the engine cooling measures, otherwise the crew's butt would be burned.

After all, the original design was a farm crawler tractor, not a manned light tank, so He Zuguang cannot be blamed for not thinking it through, this is a problem with the tire.

The diesel power of the 2.0 is too weak, if you install a big shovel and turn it into a bulldozer, and then install steel armor, it is estimated that the roadblock will not be leveled and you will fall down first, and it will not reach the strong performance expected by the earl and the military.

The only solution is to increase the power, using a mature 3.5-liter diesel engine as the main power, or even a 4.2-liter high-horsepower diesel engine that is being tested in the laboratory, then the entire girder structure of the tractor will have to be torn down and redesigned, and the subsequent series of running mechanisms will have to be redesigned, as will the steel tracks.

Major General Konrad Adenauer squatted down with a large group of experts to discuss the tractor prototype with great interest, and He Zuguang kept answering questions, turning the place into a live technical seminar.

"Professor He, which is more durable, Type A or Type B tracks?"

"According to the current field test, the B-type track performs better in load-bearing and power transmission, the steel track pin can basically adhere to 12~15 kilometers without breaking, and the A-type track performance is slightly worse, and the field test basically can't last 8 kilometers."

"Hmm...... In this way, there is great potential for further improvement in the design of the B-type track, the steel track pin can be made thicker in the improved design, made of high-quality cannon steel, the physical toughness and strength are much higher, and the two-pronged strategy should be able to solve the problem of durability, and it should be no problem to run a few hundred kilometers in theory. ”

"Professor Ferguson's advice is very pertinent and I think it works."

"Colleagues, have you considered rough driving in practice? This requires us to have enough overspace in our design. ”

"The redundancy represents the increase in the mechanical dead weight, and the balance must be found in the weight reduction and the redundancy, I think it is better to use I-beams and stiffeners in the girders, and the load wheels also have room to reduce the weight, not the iron lump is strong, and the ingenious design can achieve the same strength."

"It makes sense, I'm afraid it's hard to save the weight on the tracks, and if you don't want to increase it, you can only find a way in other aspects."

"The diesel power of 2.0 is too small, and it is a dojo in a screw shell!"

"That's true, of course it's best to use 4.2 liters, but I'm afraid I can't catch up!"

"Professors, on behalf of the military, I would like to express my position that this 2.0 liter is what we need, and 4.2 liters is also what we need, the two projects can be carried out at the same time, there is no need to worry about R&D funds and technical strength, the most important thing is time, and it is necessary to achieve the durability required by the military, and be able to run 1000 kilometers with its own power, which is the most critical indicator."

"Your Excellency, your requirements are not low, 2.0 liters of crawler tractors may meet such requirements, after all, their own weight is relatively light, all aspects of the requirements are lower, 4.2 liters of estimates are dangerous, the requirements for material strength are very high, this is not a moment and a half to get out."

"It's true, the strength of the material is a big issue."

"Seconded, the design problem is easy to solve, the key is that the performance of metal materials can not meet such high requirements, the steel track pin is made of high-standard cannon steel, if the entire tractor girder is made of cannon steel, plus such a heavy track, the cost is skyrocketing."

"I think...... You can make a few prototypes first, carry out comparative tests, and use general steel to make general steel, and the key load-bearing structure can be strengthened with cannon steel accessories, so the cost will be reduced a lot. ”

"Ladies and gentlemen, I think there is room for further improvement in the suspension structure, and the right design can make it more durable, which cannot be ignored."

……

A group of high-level experts and professors were discussing hotly, Bian Chunsong, Li Zhong and Wu Baoli gathered outside to listen with relish, and this kind of spark of ideological collision was an incomparably precious learning opportunity for them, and they couldn't ask for it.

Before you know it, it's already dark, and the experts light the lights to continue the discussion.

At this time

An officer with a captain's epaulette walked in quickly, and when he saw Major General Conrad Adenauer squatting in the crowd, he hurriedly walked over and leaned down to report in person; "Your Excellency, the army in charge of security and the moving tractor have arrived, you see......"

"Oh, let's get ready to move." Hearing this, Major General Conrad Adenauer stood up, and suddenly felt a strong dizziness in his head, and his slightly obese body directly overturned.

It turned out that he had been squatting for too long, and he stood up so violently that his brain was starved of oxygen.

This frightened everyone a lot, but fortunately, the officer next to him and Bian Chunsong reacted very quickly to support him.

They helped the general to the side and sat down, and after a few moments of relief, they felt better.

"The years are unforgiving, I think back then I followed the Earl to the thylacine rock to suppress the bandits, running around on horseback, and only sleeping for two or three hours a day was enough, but now I can't." Conrad Adenauer said with a sigh on his face, patted Bian Chunsong's shoulder lightly with his hand, and asked kindly; "Thank you, young man, what's your name?"

"Your Excellency General Hui, in Xia Bian Chunsong, is a student of Professor He."

"Okay, you young scientists and technologists are full of vigor and vitality, and you are the hope of Australia's future, do you have any ideals in the future?"

The general's words hit Bian Chunsong's heart at once, he has always been looking forward to becoming an officer, He Zhong and Poly Tsai also have such a dream, they always felt out of reach before, but now they reached out to help the general, and the opportunity to realize their dream came magically.

In Australia, the status of the military is extremely high.

Bian Chunsong looked at his companions with fiery eyes, and saw that their eyes also showed eager expressions, so he no longer hesitated, and knelt down on one knee with a sincere expression; "Your Excellency General, I have had a dream of joining the army since I was a child, but I can't achieve it as a local student, and my two companions are the same, hoping to contribute all my strength to this land we love."

"Oh...... It's a good ambition. Konrad Adenauer only groaned for a moment, then nodded approvingly.

If it's on a weekday

Bian Chunsong's request seemed presumptuous, how could it be so easy to enter the army and eat imperial food? There is no such abruptness to climb up the pole, and it is likely to be categorically rejected.

But considering the importance of the crawler tractor project, which is the Tianzi No. 1 project that Lord Earl values the most, things are much easier, it is really asking for money to give money, and it is a green light all the way.

Although the general did not agree on the spot, this attitude had already made Bian Chunsong overjoyed, and Bian Chunsong helped him up with his attentive hands.

At night, bright oil lamps illuminate the surroundings.

Conrad Adenauer regained his composure, and after looking at the large group of men and tractors in the night, he commanded with a wave of his big hand; "Let's move overnight now, and start formal research tomorrow, we don't have much time, we must make every effort to speed up the progress, come up with products that satisfy the military as soon as possible, and start ......moving now."

Order

Everyone started together, and soon all the miscellaneous items here were loaded onto the tractor, and then they walked in the direction of the Azure Weapons Company, and their figures were drowned in the night.

Red Fort

Rear Admiral Geng Guigui and Rear Admiral He Fang, the two giants of the navy, came together and once again handed over the revised "Qingtian Plan", and the idea was naturally self-evident.

For all admirals, a powerful steam ironclad battleship is the ultimate dream in their hearts forever, and there is no one.

At present, the relationship between the north and the south of Australia is tense, and a large-scale civil war seems inevitable......

In such an important historical period, the navy does not want to be absent.

Therefore, this time, the two giants of the navy came together, one is to ask for war, and the second is to re-mention the "Qingtian Plan".

In particular, Major General He Fang hurriedly ended his trip to Europe, in order not to miss this battle for the unification of the north and south of Australia, which may be the last precious opportunity to make contributions before the end of this century, or it may be the battle of the Earl's ascension to the throne, which is of incomparable importance.

"Nonsense, nonsense." Li Fushou threw the "Qingtian Plan" on the table without looking at it, strode in front of the two admirals, his tall body with an indescribable strong sense of oppression, pointed at the noses of the two generals and reprimanded; "You have nothing to do, don't you, you have to intervene in everything? I think I'm all dazed, tell me for yourselves...... Will it be able to drive warships to fight on land, or will it be ready to fight against the invincible armada of the British Empire in the oceans? ”
