Zhao Qiang and Xiao Qiangzhi have seen the power of the grenade after the explosion, but after all, that thing is small, and the throwing distance is not as far as the artillery, not to mention various restrictions, the key is that there is no artillery power in momentum.

"Obediently, Qiangzi, this cannon is really powerful, it is simply tailor-made for the army, it is definitely a sharp weapon for attacking the city, I want it. ”

Xiao Qiangzhi stroked the irregular concrete wall that had long been destroyed at the edge, and said something in his mouth.

"Cut, I think it's tailor-made for the navy, this cannon hits wooden ships, one hit one by one, and our navy wants it, this is much more powerful than that throwing car. ”

They are all soldiers, and the value of new weapons can naturally be seen clearly, and no one is a fool.

"Well, let's stop arguing, let's see what the Lord says. ”

Xiao Qiangzhi also didn't argue with Zhao Qiang, now the three armies are the most aggrieved in the Air Force, and the two of them are on par, so it's useless to fight, the key depends on Wang Xuan's attitude.

"Lord, this is the target, two catties of charge. ”

"Double the target thickening, try again. ”

Wang Xuan wanted to see how much the artillery could damage the wooden ships, so he kept asking for thicker planks and an appropriate extension of the shelling distance.

This is a terrible test, the alloy steel cast cannon can still easily break through the three-inch plank at the time of 150 zhang, which is a considerable thickness for a wooden ship.

"Okay, what is the weight of two guns of the same caliber?" Wang Xuan asked a key question while being excited.

"Back to the Lord, the bronze cannon weighs 3,000 catties, and the alloy steel cannon weighs 1,000 catties, which is one-third of the bronze cannon. ”

Guo Zhou said, he came with these data as soon as he opened his mouth.

"Due to the excellent characteristics of alloy steel, there is no need to thicken the barrel wall to resist the impact of high pressure, so the two guns look thick and thin, but the comprehensive performance of the bronze gun is inferior to the alloy gun. ”

Everyone present understands this truth, and everyone has long understood Wang Xuan's intention to attach so much importance to education and research institutes.

"The research progress of the gunpowder group is not slow, they have developed gunpowder and explosives on the basis of the composition of black powder, although the effect is not obvious, but this is a good start, so in the research of the composition of the gunpowder, you should refer to the opinions of the gunpowder group. ”

Wang Xuan said to Ge Wenbin that gunpowder is often used to launch and shoot explosives, and it can also replace the properties of some explosives.

However, the speed of the chemical reaction of explosives is extremely fast, and a large amount of heat energy and high-temperature gas are released in a very short time, causing a violent impact on the objects around the explosion point, and the intensity is much higher than that of gunpowder.

Pyrotechnic powder is often used as a smoke generator, luminescent agent and incendiary agent, and its temperament is relatively mild.

In view of this, Wang Xuan hoped to develop the first ejaculation.

Due to technical reasons, it is impossible for Jixiang to produce artillery steel of later quality, so the relatively mild firing and projectile can reduce the probability of the cannon exploding, prolong the service life of the artillery, and reduce casualties.

Ge Wenbin was overjoyed when he heard that the gunpowder group had made progress, "Okay, we will test the effect of the new shot and make a relatively accurate analysis by comparing the data, please be relieved." ”

"Artillery is a strategic material, so only the military will procure it, but I can promise you that 20% of the profits of the artillery factory will be allocated to your group, and you will enjoy the same treatment as the optical factory and the bearing factory. ”

Wang Xuan was prepared in his heart that as long as each group produced research results in the future, they would be motivated in a similar way, of course, large projects and sub-projects were treated differently.

Everyone was naturally excited when they saw Wang Xuan's statement, although research was their interest, but no one would think that they had more bonuses in these years, and it was not easy for anyone to drag their families with them.

"This cannon has to have a gun mount, right?"

After Xiao Qiangzhi and Zhao Qiang touched the concrete wall that had been hit by the shell, they also turned back, originally wanting to ask Wang Xuan how to distribute the artillery, but when they saw the broken wood pieces all over the ground, they couldn't care about everyone's interest, and couldn't help but ask.

"That's a problem, do you have a solution?"

Wang Xuan still decided to listen to the opinions of the artillery group first.

"According to the institute's public curriculum, when the projectile is pushed out by the force generated by the combustion of gunpowder, the gun itself is also subjected to a backward reaction force, which we call recoil. There are two solutions, one is to strengthen the chassis and increase the overall weight (mass), and the other is to install a newly developed spring device to reduce the impact force of the barrel on the gun body. ”

Mao Yongchang stepped forward, combined with some common sense in the construction industry, but also analyzed the head of the road.

The auspicious warships were either built of wood or reinforced cement concrete, and their seismic performance was not optimistic.

Once the war starts, it is a salvo of ship guns on the side side, otherwise it is fired in turn on ships rocking from side to side, and at the level of this era, where is the hit rate?

However, in the event of a salvo, the powerful reaction force will cause great damage to the hull and even cause disintegration.

Therefore, relying only on reinforcing the hard reaction force of the chassis is not only unreliable, but also unscientific.

Therefore, Wang Xuan agrees with the spring system retreat.

The principle of spring retraction or hydraulic retraction is similar, that is, the recoil force is transferred, and the transferred recoil force is weakened by the principle of material force until it disappears.

Therefore, to do this, it is necessary to have artillery brakes.

There are many kinds of brakes, but the muzzle brakes are not suitable for naval guns, which will affect the initial velocity of the projectile, which in turn affects the flight trajectory, hit rate and range.

Considering the current technical conditions, it is still feasible to withdraw the tube, after all, after reducing part of the recoil, the remaining recoil can still be transmitted to the sea water through the hull, unlike the fixed connection, so that the hull can instantly bear all the huge recoil.

Tube withdrawal is to support the barrel on the U-shaped cradle, and then together with this cradle to form the pitching part of the gun, on the gun carriage to adjust the angle of fire.

There is no fixed connection between the barrel and the U-connector, but an elastic anti-recoil device that connects the two, and when fired, the barrel retreats and then resets under the reaction of the spring.

This design is also suitable for army guns, and with the muzzle brake, most of the reaction force can be canceled out.

Although Wang Xuan knew that Mao Yongchang's first plan was difficult to work and there were too many restrictions, he did not refute it.

"It's good to have ideas, in terms of research input, what you want to give, what you lack to make up, you can do it boldly and with confidence, the lord's mansion is your strongest backing. ”

The hearts of the research institutes who said this sentence were surging, and while they were excited in their hearts, they also secretly admired the courage of this young lord, and it was not unreasonable for Ji Xiang to come to this point in just two years.

"The ultimate performance of the artillery must be accurately tested, what is the maximum charge of 3 inches and 20 times the caliber, how much is the maximum firing range, and what is the maximum destructive power, these data are all you need to test and complete. ”

Wang Xuan attaches great importance to this, a mature weapon must have these limit data, otherwise no one dares to use it.

"Furthermore, can you develop artillery or weapons of other calibers and uses based on the technology of existing finished artillery?" Wang Xuan began to guide their research thinking and direction, "Of course, the meal must be eaten one bite at a time, and things must be done step by step, or the same sentence, even if I smash the pot and sell iron, I will support your unremitting research." ”

Ge Wenbin, what else do they have to say, it is estimated that no one in the entire Great Xia will pay so recklessly like the auspicious lord.

"Also, I will ask the Admiralty to allocate four ships, two wooden ships and two reinforced concrete warships for you to test the recoil of the ship's guns, you don't have to care for the ships, I only need the most accurate data, for this, even if you dismantle the ships. ”

The personnel involved in the test, including the artillery research group, were all moved, and Xiao Qiangzhi and Zhao Qiang had no intention of competing for artillery.

"In view of the need for new artillery, gunpowder and other tests, the Lord's Mansion will allocate another 100,000 gold coins for the research to your artillery group. Wang Xuan continued, "In addition, the Government Council will also increase the procurement share of Xishan refined iron ore and give priority to meeting the needs of steel for artillery research." ”

June 15, 56 Xia Yuan calendar.

The outer guard wall of the Hexi Heavy Industry Zone is being built, and the bearing factory and artillery factory inside are also in full swing.

Xiao Hei has barely closed his eyes in the past few days, this is not only the industry of the lord's mansion, but also the military industry.

In other words, if it is only the property of the lord's mansion, it doesn't hurt to have some baskets, and the name of Wang Xuancaizi has been verified by practice.

But the military industry is a different matter, leaking secrets, even if he Xiaohei has nine heads, it is not enough for Wang Xuan to cut off.

Only then did he understand what Li Yugang meant at the beginning, and the pressure was pressing on him like a mountain.

The 500,000 gold coins looted from the Red Flame Lord's Mansion have all been invested in the renovation of Hedong Pedestrian Street, and Wang Xuan has to support the army and provide research funds for the research institute, and his hands are suddenly tense.

Yongsheng's share alone was no longer enough to cope with the huge expenses of the lord's mansion, so Wang Xuan began to plan to sell wine.

Dry brewing and wet brewing have accumulated a lot, so Wang Xuan released the news that the first auspicious liquor agent recruitment meeting will be held at the end of June.

As soon as the news came out, the lush auspicious shopping mall was silent for a few days, and then it boiled violently, this is not fake news!

The five major newspapers and periodicals made every effort to build momentum, and in only five days, people in the royal capital got the news.

At the 55-year auspicious commodity fair, Wang Xuanke gave away 168 bottles of liquor, most of which were foreign businessmen.

The so-called has a good reputation, there are many people who drink it, and the reputation is good, so it is difficult to think of being famous.

Therefore, after some good wine people learned about it, they rushed to Jixiangling, and they couldn't act as an agent for the sales right of a region, at least they could buy a few more bottles on their behalf to satisfy their cravings.

The merchants even tried their best to find out the inside story, this liquor is no more than porcelain, perfume and glass, the audience is too wide.

Wang Xuan knows that liquor is actually a type of drug.

What are drugs? It is something that is addictive when you use it, and it is fatal to use it.

After the news of the sale of alcohol spread, Wang Xuan and a number of high-ranking military officials soaked in the test site almost all day long, and every time the rumbling cannon sounded, Wang Xuan had a feeling of 'I'm back again'.

The maximum charge of the bronze cannon is 2.5 catties, while the maximum charge of the manganese steel cannon is 3.5 catties, and the effective firing range has reached 200 zhang, which has shocked the eyeballs of the ground.

Subsequently, Wang Xuan issued an order to produce ten alloy steel three-inch guns, and he wanted to practice in actual combat.

Liang Dahai is very concerned about the newly built artillery factory next door, the two are not competitors, the steel mill will be stained with the light of the artillery factory, how can private enterprises have the rapid development of military enterprises.

As the experiment continued, after various limit conjectures were constantly broken, Xiao Qiangzhi and Zhao Qiang finally couldn't bear it.

"Lord, you comment, this cannon should be given priority to the army, with us guarding, no one wants to step into an auspicious half-step. ”

After Xiao Qiangzhi participated in the artillery test, he went back and told his colleagues in the War Department this information, and instead of touting it as expected, he complained a little.

The reason is very simple, you don't even rush to apply for equipment for the army with such a powerful weapon, I don't know if the crying child has milk?

Therefore, since Xiao Qiangzhi hit, he has always paid attention to the progress of the experiment.

When he learned that Wang Xuan ordered the production of ten artillery pieces for actual combat training, he knew that the opportunity had come.

"I said Lao Xiao, with our Admiralty here, which one dares to come and spread wild, and which one can cross us and step into auspiciousness?"

Zhao Qiang is not to be outdone, the Admiralty has been very tight recently, and the generals below are counting the days waiting to equip artillery.

Wang Xuan ignored the two, knowing that most of them were performing, and they wanted to get the exact date and quantity of their respective branches of artillery equipment from him.

"Okay, the navy and army treat everyone equally, they all have it, just get out of here if it's okay, and if you don't leave, you will squat in a small black house!"

Before Wang Xuan's words fell, the person was gone......
