I, the patron saint of the frontier of the Tang Dynasty, was forced to rebel

Chapter 117 Shocked Friction Welding

"Are you sure you're right, instead of using Huomelting?"

"I certify as an admiral that I have not lied a single word."

Seeing such a serious dialogue, everyone felt very puzzled.

Especially zhang qingyang, who even thought he had said something wrong, seemed a little nervous.

Historically, King Xian hated those bureaucratic practices the most.

"My lord, this method is also forced out of helplessness. The shipyard has used the fire-melting method, but the end result is that it cannot last for more than six hours and cracks appear directly, and even the machine is in danger of breaking when it is turned on!"

Qin Mu didn't blame them for the wrong way, but was shocked!

Shocked by this welding method!

Friction welding. Before the rebirth, the world's number one air force, the beautiful country, was the first to use it to weld the engine blades of the most advanced fighter Raptor!
It took decades of research and development to sit.

Now, what era?
In the Tang Dynasty, a shipyard that had just been established and hadn't even existed for two years actually developed such a technology.

Can it not surprise people~!

Friction welding refers to the method of using the heat generated by the friction of the contact surface of the workpiece as the heat source to cause the workpiece to undergo plastic deformation under pressure for welding.

Under the action of pressure, under the action of constant or increasing pressure and torque, the relative motion between the welding contact end faces will generate friction heat and plastic deformation heat on the friction surface and its surrounding area, so that the temperature of the nearby area will rise to a temperature close to but Generally below the melting point temperature range.

But this requires extremely high requirements on the material, a solid-state welding method that realizes welding through molecular diffusion and recrystallization at the interface.

Can't imagine how they did it.

"King Xian, is there something wrong with this method?"

Zhuge Liang watched Qin Mu sink into deep thought, and carefully reminded him.

"Uh no, it's nothing, there is a first time for everything, as long as the experiment can pass."

He turned his head and looked at Zhang Pengfei, "How much horsepower can the current steam turbine achieve?"

"About 60.00 horsepower, but it's unstable. If you want to make the material more durable, you can only maintain a power of about [-]%, otherwise there will be a threat of reduced lifespan or even a fryer!"

Speaking of this, Zhang Pengfei turned around and pointed to the distance, "The ship is propelled by a three-blade propeller, and its maximum speed can reach about 35 kilometers. If it is turned on at full power, it can reach 43 kilometers, but it can't be done when it is not necessary."

Qin Mu nodded. He was very clear about this situation. Even the ship before rebirth couldn't guarantee that it could last for a long time at full power.

The approximate data for this experimental ship is that it is 51 meters long, 15 meters wide, and has a maximum water holding capacity of [-] meters. The layout adopted is also very advanced.
At the beginning of the design, he directly suggested not to follow the original ship model design, and proposed the concept of a slender hull.

The total number of rows is as high as more than 240 tons, and the total weight of the hull is [-] tons.

The empty load is as high as 380 tons, including basic living materials and personnel.

The standard load, that is, the safest weight is 750 tons, and the maximum is [-] tons.

The speed is not good, but it is considered extremely strong in this era.

35 kilometers per hour, the range of a day is only 350 kilometers, and the combat radius is currently estimated to be [-] kilometers.

The minimum speed can be reduced to thirteen kilometers, and the continuous voyage can be as high as ten days.

If it is used for patrolling, as long as the logistics can keep up, it will be fine to stay at sea forever!
Coal, is a big problem.

"This ship consumes a lot of power, right?"

"King Hui Xian, it is indeed very big, but various research institutes are also intensively researching. Currently, high-quality pulverized coal is used as the combustion material, and the temperature is raised to reduce consumption."

"How can the high temperature in the boiler room withstand the pressure?"

"The refractory brick can currently achieve a pressure resistance capacity that is two cups higher than that of the original power room."

Qin Mu nodded, very satisfied.

If you can't make really good refractory bricks with such detailed information, you might as well eat dirt.

After leaving the power room, Zai returned to the deck.

The 240mm artillery is still very eye-catching, and there are actually eight lower-level artillery on both sides of the hull!

240 mm is the main gun, only one.

The secondary gun is 150 mm, but with an additional normal barrel, the range has increased a lot.

This was also what zhang qingyang was most proud of.

"Your Majesty, although this caliber is the same as that of land artillery, it actually has a very high range and attack speed."

"Oh?"

Qin Mu smiled, but didn't mention it.

He doesn't know much about naval ships, etc., but he knows a little bit.

After all, his predecessor was an army staff officer.

"How to say?"

Zhang Pengfei smiled mysteriously, and pointed to the 150mm gun barrel, "I heard that the Lingzhou Army equipment is researching rifling a few days ago, so I wondered if this thing can be used on artillery."

"So...you did this?"

Qin Mu was taken aback, "Do you know what the consequences will be if there is even the slightest mistake in the depiction of the rifling?"

"Your Majesty, the minister finally obtained a usable finished product after a lot of tests. The current accuracy can be more than double the estimate, and the initial speed is even more terrifying, but there is also a problem."

"what is the problem?"

"The risk of bombing has increased!"

Hearing this, Qin Mu immediately thought of something, and looked back at the muzzle of the gun. It was very primitive, and there was no modern device to eliminate the muzzle flame.

That thing is not simple, that is, when the gun is fired, the barrel is under great pressure, and the spray from the muzzle is scattered to both sides, and the energy is concentrated in the center to ensure that the rotating shell will not deviate from the target due to the muzzle velocity and the acceleration of the rifling.

At the same time, it can also increase the concealment and eliminate the fire.

From zhang qingyang's words, he immediately guessed the problem.

Immediately, he laughed.

"This question is simple. Do you know the flame arrester of the army artillery? You can use it."

"But I tried it, it will cause the muzzle velocity to decrease."

"If you want stability, you have to lose a certain initial velocity. Ship artillery is different from land artillery, especially the design of the caliber is even more different. Starting from here, the problem can be solved."

This ship, when fully loaded with a stable crew, can take 120 five people.

It has to be said that the creation of such a thing in this era has exceeded everyone's expectations.

A ship is comparable to tens of thousands of elite soldiers!
Attacking the enemy army dozens of miles away will not be threatened, it can be said to be invincible!
After looking around, Qin Mu noticed after getting off the boat that the warships in the dock seemed to be different from what he had imagined.

One by one, the square iron plates are pasted on the periphery. How does it look like reactive armor?

"What is this?"

He didn't understand it. Reactive armor definitely couldn't be developed, but it was possible to replace it with steel.
