I am the king in troubled times Chapter 85 There are always more ways than difficulties
The difficulty in the hit rate of naval guns lies in the fact that the side guns cannot be fired synchronously, resulting in the deviation of the trajectory of the late-firing guns.
Ge Wenbin mentioned that shortening the length of the fuse indirectly shortens the time interval between artillery fires, but it does not fundamentally solve the problem. Moreover, the fuses produced by Jixiang have inconsistent combustion times and cannot be so precise.
As for switching to single gun shooting, it is even more undesirable, naval battles are changing rapidly, and the enemy will not stop there waiting for you to aim.
Everyone was also evaluating the feasibility of the two proposals, and for a while, all that was left in the conference room was the sound of banging on the table.
"What do you think?" asked Wang Xuan.
The crowd exchanged glances with each other, and they knew very little about artillery.
Wang Xuan did not expect them to be able to provide technical help, but asked in the hope that they would be able to rationally use tactics and tactics under the existing conditions to bring the power of artillery into full play, which is the quality and skill that fleet commanders should have.
"Actually, there is no need to pursue the same fire of artillery, there are waves on the lake, if the waves are greater at sea, the hull itself is constantly swaying, rather than pursuing consistency, it is better to pursue the coverage density of the shelling. ”
The one who spoke was Song Feng, the captain of the Jijia ship, who had fought with the Song clan's naval army in Xingyao Lake, and was also the only captain with actual combat experience on the scene.
"In addition, we can strengthen the defense of the warship, use the advantage of maneuver to close the distance between the two sides, and shoot at close range, and the accuracy will be less important. ”
This is also a way, to shorten the distance, if you hit me, it hurts, and I hit you to the heart.
With Song Feng taking the lead, everyone also put forward their own opinions one after another.
"Sea ships will be much larger than river warships, and there will be much more side guns, and there will even be a two- or three-story layout. In this way, it is possible to launch an attack by means of full salvo, split salvo, partial salvo, continuous fire, etc. If the number of gunboats is large enough, even if it is a sectional shelling, the coverage of the bullet rain will be large enough, and it is completely possible to achieve decisive results after the three rounds of shelling. ”
This is the pursuit of quantity, using quantity to make up for quality, and punching the master to death, which is consistent with Song Feng's opinion.
"When it comes to accuracy, the experience of the gunner and the gunner is very important, and without a certain tacit understanding, it is impossible to carry out orders and prohibitions; without sufficient experience, there is no confidence to talk about accuracy. ”
The atmosphere is gradually getting hot, Wang Xuan is also thinking about the development trend of the navy in the future, as far as he is concerned, neither density nor accuracy can be missing, this is walking on two legs, and neither leg can be lame.
"If the number of guns is increased, the size of the ship will increase, and the gun deck will need to be laid with wood to reduce the damage to the hull caused by vibration. Mao Yongchang added that based on the maximum charge tested so far, the recoil of the gun is much greater than expected.
"Yes, judging from the test results, the standard charge of a three-inch and twenty-fold caliber gun is four and a half pounds, the projectile weighs five and a half pounds, and the recoil is twice as large as expected, so shock absorption will be a problem that we urgently need to solve. Ge Wenbin also explained.
"Is it possible to consider increasing the trajectory of the reverse movement after the artillery fire?" was mentioned.
"You mean, to extend the running distance to reduce the tremor caused by the recoil?" Ge Wenbin was curious.
"Exactly, the artillery is not fixed in the same position, so that when shelling it moves back on its own, the effect on the hull, as well as on the accuracy of the fire of other guns, is much less. ”
Wake up the person in the dream with a word, even Wang Xuan was a little surprised, this is really a good way, so he couldn't help but look at the officer a few more times.
"It makes sense, if you add springs and some other auxiliary equipment to the track, the gun can be reset quickly after firing, it makes sense!"
Ge Wenbin said that writing and drawing in a notebook is a necessary quality for researchers, recording inspiration anytime and anywhere, in case of emergency.
The meeting lasted until midnight, everyone was still in good spirits, Wang Xuan couldn't bear the thick fatigue and went to sleep.
On 13 September, God lost his temper, the rain was raging, the water was surging, and the live-fire drill began rain or shine.
On rainy days, visibility is low, and it is difficult to judge the impact point, which is also the reason why Wang Xuan insists on continuing.
In the course of the exercise, there were many conditions, either the ammunition was damp and could not be ignited, or a large wave struck and poured into the muzzle of the gun, and there were even incidents of gunners being injured by mistake.
Zhao Qiang's face turned black into the bottom of the pot, and he asked Wang Xuan for punishment.
"It's not terrible to make mistakes, it's terrible to keep making the same mistakes. ”
After saying this, he no longer bothered with Zhao Qiang and let him understand it on his own.
After the shells were fired, the two wooden target ships had turned into duckweed floating on the water, undulating with the waves.
Wang Xuan ordered people to salvage the floating debris and tow it back on two cement boats full of craters.
In the afternoon, they landed and went straight to the artillery factory, where the problem of mass production of barrels was to be solved.
"We use the casting method to produce, and we can produce a qualified barrel in an average of three days, and the yield rate is about 30%. Ge Wenbin introduced from the side that he was the temporary person in charge and wore many hats.
These Wang Xuan are well aware of the advantages and disadvantages of casting and forging, and he came to the gun factory to combine casting and forging.
Researchers also know this, but the barrel is a large object, and it is impossible to improve the quality by repeated hammering, so they are also difficult to cook without rice.
After turning around, Wang Xuan ordered someone to get a wooden model from the lord's mansion and went to the steel mill next door alone.
Liang Dahai gained a lot of weight, had a big belly, and was wearing a new T-shirt from the garment factory, and a pair of cyan trousers on his lower body, which gave Wang Xuan the illusion of returning to the past.
"It seems that life is going well. ”
"Thanks to the young master, our steel mill business is thriving, and as soon as the heart is wide, the body will be fat, hehe. ”
"Can this be done?"
Wang Xuan took out the wooden model, which was divided into two parts.
Underneath is a cylinder with a hole in the middle, in which a solid wooden stick is placed.
Above is a hollow wooden stick that can be tightly inserted into the circle below, wrapping the solid wooden stick and controlled by the pulley above.
"What is this?"
"Forging press, beggar's version. ”
Liang Dahai didn't understand the meaning of the beggar version, but he could see the purpose of the model.
"It's exquisite, and the master's craftsmanship is getting more and more exquisite. Liang Dahai looked around the head-sized model.
"This is what Wei Xing did last month, how can I have that skill, you can say if you can do it." ”
"This guy should be used to forge cannon barrels, if it was two months ago, it would definitely not work, even if it was made, it would not be used. Since the research institute shared the research results of low, medium and high carbon steel with us, it is no longer a problem. ”
Low carbon steel has strong plasticity and low strength, and is mostly used in structural bearing; medium carbon steel has plasticity and moderate strength, and is used for mechanical transmission, gears, etc.; high carbon steel has high strength and hardness, and is mainly used for cutting tools.
Liang Dahai is very confident, "As long as the detailed data of each component is given to us, we are responsible for making it out with confidence." If this happens, the production of those strange-shaped tools and spare parts will be much simpler, build a stamping machine, plus supporting molds, how can you produce a thousand eight hundred a day, how can it be like before, swing a hammer and sweat tired half dead, not to mention, half a day to knock one out. ”
This fat man can see quite far, high-carbon steel is also called tool steel, and you can know its purpose from the name.
With the large use of machines, various types of metal parts will spring up like mushrooms after a rain, which will bring earth-shaking changes to the industrial manufacturing industry, which is a qualitative improvement.
These special tools will feed back to the precision machining of machine tools, lathes, milling machines, planers, drilling machines, boring machines, grinding machines, gear making machines and other industrial machine tools have the opportunity to appear, the picture is too beautiful, dare not see or think.
"After a while, the researchers of the artillery research team will come over to discuss the details and parameters with you, and you also know that this big guy is used to forge the barrel, so you should be more aware of the material requirements of the key parts. ”
Wang Xuan reminded from the side that the production of various machine tools will be a new profit point for steel mills, but the premise is to build a barrel forging press, which is not only a machine, but also a sign of the new era.
Once successful, is the musket still far away?
"I know, I know all this, I will communicate carefully with the people in the research institute, I know the meaning of this machine tool, I will not slap a swollen face and become fat, I will build it wholeheartedly. The fat man's expression was serious, and he changed his previous casualness.
After another two days, several lords who came to Jixiang to do business still did not have the will to meet, according to the person in charge of the Jixiang Hotel, these people were hooked on mahjong.
After getting up in the morning and washing up, I will go to the stall outside the east gate to eat breakfast, as if I prefer egg cakes.
After eating breakfast, they would walk around in a carriage, read the newspaper by the way, and then several people would get together to play mahjong.
In the afternoon, I often go to the Grand Theater to watch plays, or listen to cross talk, or enjoy sketches, recently "The Legend of the White Snake" is very popular, and I have seen a lot of big girls and little daughters-in-law cry.
At night, I love 'Dream Auspicious', and people can control it, slightly drunk, but not drunk.
In stewardship's words, thieves have regularities.
Wang Xuan has been very busy recently, and since people are entertaining themselves, they don't bother.
During this period, the artillery research team communicated frequently with the technicians of the steel mill, and the construction was about to start.
The difficulty was not in the sheer volume of the machine, but in the hollow circle on which the barrel was placed on the base, and in the solid rod in the middle.
It not only requires the outer wall to be round and smooth, without flaws, but also requires stable structure, anti-compression and compression.
On the seventeenth, the sky is beautiful, the sky is cloudless, and the wind and the sun are beautiful.
The steel mill is in full swing, and the casting of the barrel forging press is divided into three steps, the first step is to cast a solid rod, and then put it in the mold for forging, and the height is compressed by ten centimeters to increase the strength.
The second step is the casting of the upper hollow tube, which will be combined with a solid rod after forming and then forged to improve its strength.
The third step is the casting of the machine tool skeleton, and the steel mill digs the model in the ground, lays the resistant material, and casts it directly.
The rest is to assemble, and the test is the accuracy of the fit between the upper and lower rods and the hollow circle.
Wang Xuan did not go to the scene to watch this process, he worked in the Government Affairs Yuan, but from time to time he came to the balcony and looked south, and his heart was not quiet.
