Of course, there are also many problems in Yasuo's modification design. First of all, the solid iron pillars need to withstand the dual stress of heavy objects and artillery impacts, and their service life is very limited. Once the battle becomes fierce, these two solid iron pillars may break.<

/p>

In addition, the deformation force of the hollow iron frame is also very limited. The recoil of such a heavy artillery is also a technical problem in itself, how to weld a strong tripod that can withstand such recoil.

However, Alphonse thought that other materials could be used to fill the tripod, and oak with high elasticity is a good choice.

The deformation force received by the tripod will be transferred to the oak, and the oak will be transferred to the slide rail below, the slide rail will be transferred to the sleepers, and the sleepers will continue to be transferred to the hull; the deformation force decomposition level by level can greatly reduce the stress of the triangle.

The deformation loss of the tripod is at least as long as that of the slide rail.

As for the solid iron pillar, Alphonse had to knock on the drawing and said: "The iron pillar cannot withstand such a large force. The artillery weighs several thousand pounds, and the recoil force is tens of thousands of pounds! These recoil forces are transmitted to the iron pillar immediately, and

There are still more than a thousand pounds of weight pressing on it, and the iron pillar may break at any time, which will definitely be a disaster."

"Perhaps we can make the iron pillar as thick as possible?" Yasuo thought for a while and said.

"No, the iron pillar is too thick, and the lug will break." Badis said without hesitation. If the iron pillar is too thick, it will be too heavy, and the recoil will be reflected to the lug, which will be a greater disaster.

:The barrel flying up, the barrel bending, or even exploding the barrel are all possible terrorist incidents!

"Then change it to a rope?" Yasuo frowned. Although the cable can provide elasticity to solve the problem of deformation and breakage, the low bearing capacity will still bring great uncertainty.

"Iron cables, maybe you can use iron cables to pass through the cannon earrings and cross the cannon body to hold down the cannon barrel. How about it?" Badis thought for a while and suggested: "You can also connect it to something similar to a city gate.

For the equipment of the hanging door, when the recoil of the artillery pushes the gun mount upward, it will also consume a lot of force while pulling the iron cable."

"Yes, use iron ropes! We also use iron ropes when hoisting the cannon to clean the barrel. If this is the case, we don't even need heavy objects!" Yasuo said happily.

"It's not that simple." Alphonse shook his head and explained: "The iron rope provides binding force, so when we hoist the artillery, it will become a drag, and we need more reloading time."

"How about changing the shape of the cannon lugs and using slide rails to clamp the cannon lugs?" Yasuo asked again.

"Let's all go back and think about it ourselves. I think this improvement is very meaningful. We can spend more energy thinking about it." Alphonse smiled and said: "We have solved one direction of the artillery, and the artillery truck will naturally also need to

More perfect."

"Yes, that's what I think. We need to think about it carefully." Yasuo said happily. Since Alphonse did not reject this idea, it means that in his opinion, his idea may not be wrong; just like this time

For the prototype gun, he proposed the correct direction of transformation, and Alphonse finally made the drawing design. Now the prototype gun has been successful, and I hope the same can be said for the gun truck!

As soon as he returned to the house, he got the news that Mrs. Desai invited him and Armand to a banquet in the evening, which made Alphonse really dumbfounded:

I originally thought that Armand should stay away from Veronica. It would be better to pack the luggage after getting the frame template tomorrow and get out of here at dawn on Monday morning! Who knows that Mrs. Desai is still sending the sheep into the tiger's mouth, and he also

I wonder if parents in this era are too caring...

"Zach, how are you?" Alphonse walked into the backyard again and saw Zach sitting shirtless on the ground. In front of him was a wooden basin filled with water, and he was grinding something with a grindstone in his hand;

When Alphonse walked in and took a look, he discovered that he had soaked a piece of glass in water and was carefully polishing the mirror surface!

"Sir, of the 6 pieces of glass I brought to the glass workshop today, only 2 were flat. Using the method you taught me, I quickly tinned two good mirrors; but these pieces cannot be used.

You also paid for the glass, so I want to polish it again, maybe it can still be used." Zach replied, wiping the sweat on his forehead with his hand.

"You can give it a try, but it doesn't matter even if you fail." Alphonse nodded and took a look at the two newly made mirrors. He found that they were indeed very delicate, with no wrinkles at all, and then nodded again.

He smiled and said: "If you grind out the remaining glass, you can make a mirror for yourself, which will be a reward for your extra work."

"Thank you, sir, thank you, sir, this is great!" Zach said happily.

"Don't be too happy. It's hard to say whether you can polish it off." Alphonse smiled and shook his head. He took the two mirrors made by Zach back to the front yard and handed them to Alfred.

He planned to put frames on the mirrors when the carpenter came to deliver the frames and the construction shed tomorrow; then he would put one in Alphonse's room for his own use, and the other would be taken back to the manor for Armand.

With nothing to do, Alphonse returned to the study and sat down. He took out a pen and paper and began to think about the design of a new gun carriage. I have to say that Yasuo's improvement ideas are very good, but it is a pity that the material problem cannot be solved at all.

Ultimately, some compromising adjustments must now be made.

Compared with the frame-retractable anti-recoil device designed by Alphonse, Yasuo's design is between the tube-retracted type and the frame-retracted type; its biggest advantage is actually not to reduce the recoil, but to reduce the projectile angle of the artillery.

Fluctuation, that is, improved shooting accuracy.

Therefore, Alphonse’s idea is to decompose the optimization direction and make targeted substitutions.

The first thing to face is the problem of the barrel retreat. If you want the gun barrel to have a shooting angle, the hanging weight must exceed the weight of the artillery; but considering the strength of the rope, the strength of the pulleys and the weight of the counterweight, we must also consider

Using a counterweight that exceeds the weight of the barrel to suspend the artillery will cause years of wear and tear on the gun lugs, which cannot be ignored;

So what Alphonse can think of is to compress the tilt angle and increase the friction of the artillery's retreat, so that the gravity caused by the retreat does not exceed the friction!

As for this tilt angle, Alphonse has spent a long time calculating it, and the result is plus or minus 6.5 degrees; as long as the tilt angle required for shooting the cannonball does not exceed plus or minus 6.5 degrees, it can be completely controlled by the weight of the cannonball.

The position is fixed. As a result, Alphonse’s design ideas are greatly opened up...

In the study, Alphonse began to draw pictures quickly with a pen. Even Alfred knocking on the door many times to remind him that he was going to Desai's house for a banquet was completely forgotten; at this time,

Even if it is a big thing, it is not as important as his artillery carriage...

"Why hasn't Alphonse come yet?" Armand stood at the stairs in a well-dressed manner and asked Alfred loudly. In his opinion, is there anything that cannot be dealt with after the banquet?

He originally wanted to knock on the door of the study directly and pull Alphonse out of the study, but Alfred stopped him without hesitation; but he asked Alfred to knock on the door, but he knocked three times.

I don’t see Alphonse coming out.

"The master is busy with something very important, please wait a moment." Alfred replied.

"Wait, wait, when? Madam's invitation will be late too, what important things is he busy with?" Armand said angrily.

"Sorry." Alfred actually wanted to say that Alphonse was busy with more important things every day than going to the banquet; but in order to avoid unnecessary trouble, he had to swallow his anger and look at the playboy-looking man.

Armand was cursing there.

"I have to leave first. If he still doesn't come over, I won't apologize to Madam for him." Armand walked back and forth in the hall for a few more steps and then said.

"Yes, I will let Artu drive the car for you." Alfred also played a trick: Artu was not very familiar with the roads, and he went out at night, so he asked him to drive Armand the car.

It’s not a good idea to go around in several circles!

"Where's old Anda?" Armand didn't like Artoo who he exiled here very much.

"He drove around Calais with you today and is feeding the horses now. Do you want to wait for him?" Alfred asked with a smile.

"Feed the horse now? Forget it, Artu, just Artu, let him hitch the carriage right away." Armand cursed again and left. After leaving the door, he hurriedly got into the carriage and asked Artu to drive quickly.

The Desai family attends a banquet...

The result was that Alphonse left the study twenty minutes after he left, then went to take a shower and change clothes, and then hurried to Desai's house in the carriage driven by Old Anda, and he was still able to catch up at the door

Enter Armand who is about to enter the door of Desaix's house...

"I thought you didn't know how long you were going to hide in the study." In front of little William, Armand complained harshly to Alphonse without any shame.

"Huh." Alphonse was too lazy to pay attention to him. Without working so hard, he couldn't even get an order to process the frames for himself; how dare you pretend to be a smart guy in front of him?

"Has my brother hired a famous mirror maker? Winnie likes the mirror you gave her very much." Little William said to Alphonse with a smile.

"It was just finished today, so I rushed to send it over, but I forgot to put a frame on it." Alphonse replied with a smile, but did not directly answer whether he hired a mirror maker.

"Did you really make a mirror?" This time it was Armand's turn to be confused. Mirror, how much does it cost?

"Winnie has her own favorite frame, and she is waiting for her father to go to Venice to buy a mirror for her." Little William said with a smile: "It seems that my father does not need to go to Venice specially for her."

"Venice is not peaceful right now." Alphonse shook his head and said: "The Ottoman Empire's pirate ships are showing off their power in the Mediterranean again. Venice's trade routes are probably going to be cut off for a year or two."

"Yes." Little William nodded and replied.
