Chapter 1007 Naval Cannon

After the gunpowder smoke cleared and the safety whistle rang to confirm that there was no danger of subsequent explosions, Lin Shenhe and Bai Yu poked their heads out from the bunker—explosion accidents are not uncommon for people engaged in the weapon industry, and artillery explosions are even more serious. It is commonplace.

The two walked cautiously towards the wreckage of the cannon. The 70mm naval cannon fell to the ground, and the muzzle had been blown into a trumpet shape.Various parts twisted, looking very miserable.

"The power of the new charge is good." Bai Yu squatted down and carefully observed the blown-up muzzle, which was distorted like a morning glory.It's hard to imagine that hard steel can be torn and twisted like this - this is the power of explosives.

"I just don't know if it's a fuse problem." Lin Shenhe said.There are various reasons for the bombing of the artillery, and it is not necessarily the premature explosion of the shell caused by the failure of the fuze.This 70mm cannon is an early product of the metallurgical and mechanical department, and its quality is relatively low. It has been equipped on the 8154 for a long time, and after it is dismantled, it has been used as a test gun for a long-term shooting range.Maybe there was a crack they didn't see.

Bai Yu didn't speak any more, he looked through the wreckage carefully, then suddenly put on cotton gauze gloves, and took out a twisted metal part from the blasted gun barrel that was still hot and emitting white gas.

"Watch out..."

"It's okay, the detonator has already exploded." Although Bai Yu said so, he still carefully put the wreckage into the rattan basket.

It was the fuse.Although distorted by explosions and fireworks, the general result can still be seen.The specific analysis can only be known after careful disassembly in the laboratory.

The results of dismantling proved that the cause of the explosion was the premature firing of the firing pin caused by the failure of the spring.Although he lost a rifled gun, Lin Shenhe finally got the result he wanted: at least, the fuze made of wrought iron wire can be used on low-velocity artillery such as mortars, mortars, and howitzers.

According to Lin Shenhe's overall plan, the artillery upgrade plan should be launched immediately after the new fuze is finalized, from the current smoothbore gun system to the rifled gun—at least the equipment system of the front-loaded rifled gun.

To this end, he had already drawn several blueprints of new army artillery, and made two experimental prototypes in the mechanical department, which were tested in several exercises.

However, the Planning Institute is not interested in this. With its usual stingy attitude, the Planning Institute said that the current smoothbore artillery equipment system has only been established for less than two years, and many artillery pieces have been in service for less than [-] months. It would be great to upgrade them immediately. Wasteful, and therefore do not agree to upgrade the Army's existing artillery system.

Therefore, the biggest beneficiary of the new grenade fuze is the navy-all rifled guns are currently equipped by the navy.According to the plan, the naval guns equipped with Project 854 and Project 901 are all rifled guns.

Zhang Bolin was dejected: "You put in a lot of effort, and all the benefits were taken by the navy..." Although Lin Shenhe was not a member of the army, he had been a company commander at one stage anyway, and he had eaten with the army. Meal in one pot.So Zhang Bolin still regards him as "one of his own".

"It doesn't matter. After the engine is finished, it will naturally be the time to storm the army and the cannon." Lin Shenhe comforted him, "How about it, do you want to go to the Nanhai Cafe for a drink at night?"

In the evening, Lin Shenhe was the host of Nanhai Cafe and invited Zhang Bolin, Ying Yu, Bai Yu, Xu Yingjie and others to drink together.The reason why Xu Yingjie was invited was not only because they are colleagues now, but also to comfort their opponents: the 0017 project presided over by Xu Yingjie suffered the same fate as the new artillery—shelved.

The trial production of picric acid was very successful. Xu Yingjie used the phenol accumulated in coal coking production and adopted the sulfonation process to successfully produce picric acid explosive.Although the sulfonation process only needs to use nitric acid and sulfuric acid, the production conditions are not harsh, and the yield is not bad.However, after a comprehensive evaluation by the Planning Institute, it is believed that the immediate production of picric acid requires a new workshop to manufacture a complete set of production equipment.

"Under the current state of quasi-war, we must first consider the continuity and convenience of production, rather than rushing to apply new technologies and processes." Wu De mercilessly shot the 0017 project at the meeting of the Planning Institute, announcing it as "Technical reserves" will be mass-produced when the "time is ripe".

From the very beginning, Lin Shenhe had foreseen such a result-although high-density black powder is definitely not as good as picric acid in terms of performance, it is better in low cost. It is self-evident what choice the planning institute known for being stingy of.

Everyone drank nonsense in the cafe, and when they were half drunk, Lin Shenhe quietly paid the bill and slipped out.

"Old Xu, I'm sorry. There is also Berlin." Lin Shenhe said in a low voice.Zhang Bolin will definitely be even more upset if he knows what he is going to do soon - he will install artillery for the navy's new warship early in the morning, and Zhou Ke, the project leader of the first shipbuilding and maintenance plan, asked him to go to the site to inspect it in the evening .

When Lin Shenhe returned to the apartment, Shenye had already prepared his mountain bike—it was distributed to the elders for personal use. Although many people like 28 bars, Lin Shenhe would rather ride a more comfortable mountain bike .

"Be careful all the way." Under the advice of his sister, Lin Shenhe quickly rode on the road to Bopu. The small train to Bopu was not allowed to run at night unless he was willing to take the risk of taking a truck.There are gas street lamps on the road, but they are quite sparsely arranged, and the road surface can only be barely seen, but at least the lights mark the boundary of the road surface, so that they will not go outside the road on a moonless night.

There are headlights with self-generating power on the mountain bike. It is the light of the headlights that Lin Shenhe can safely and boldly gallop on the road-of course, there will be no pedestrians and vehicles on this road now.Moreover, the area along the road has been upgraded to a green zone, and there is no danger for the elders to walk alone.

On summer nights, with cool breeze blowing, it was very comfortable to ride a bike on the road, but the headlights attracted a lot of flying insects, flying around his bike, which made him very annoyed.

In order to arrive as soon as possible, Lin Shenhe did not enter Bopu Town, but directly took a bypass to the naval base.

After passing the inspection of the sentry and riding for another 10 minutes, the figure of the 854 modification project finally appeared in front of his eyes.

The 1630-class iron-ribbed wood-hulled flying shear cruiser is not a huge battleship.Its standard displacement is only 1160 tons, it is 70 meters long and 9.9 meters wide.In the old time and space, even the fourth-class sailing battleship of the 18th century had a larger displacement than it.But in this time and space, it is an out-and-out colossus.Although some large ships of the kiloton class had appeared as early as the 15th century, they were very few in number and rarely appeared at sea.When its hull was launched at a high altitude, it attracted the attention of many people-although they are used to seeing large iron ships of [-] tons, it is still very strange that a large ship beyond imagination was built right under their noses. dramatic.

The ship, painted light black, is now moored quietly at the Bopu Navy Pier, and the outfitting has been basically completed.Only the installation of the final deck guns remained.

On the wharf in front of the hull, there was a temporary work shed that was brightly lit. Under the high light of the steam lamp, the veteran engineers in charge of shipbuilding affairs headed by Zhou Ke were discussing the implementation plan of the final outfitting project of the 1630 class.

The artillery arrangement plan of the 854 modification completely abandoned the orientation of the multi-deck artillery positions-although many people were obsessed with the spectacular scene of dozens of artillery firing sequentially on sailing battleships in the 18th and 19th centuries, but for the hybrid made by Lingao In terms of the structure of the battleship, such an arrangement of artillery positions is inappropriate - and with the technological capabilities and industrial level mastered by the Senate, there is no need to copy the sailing battleship,
The 1630 level completely abandoned the practice of arranging gun positions in multiple layers under the deck, and changed all of them to arrange artillery on the deck.The center of gravity of the sail warship is high, and the arrangement of the artillery below the deck has the consideration of stabilizing the center of gravity.Now the weight of steam engines, boilers and coal bunkers is fully capable of stabilizing the arrangement of artillery below deck in the past.

Since the artillery is arranged on the deck, the number of artillery will not be too many. The power of the artillery must be large enough. Not only must it be able to deal with the largest European ships in naval battles, and the firing speed must be fast. needs.

To meet such requirements, the various smoothbore guns currently equipped on naval ships: from 12-pound cannons to 32-pound Caron guns, including the heaviest 68-pound Caron guns among the current naval naval guns, are difficult to meet-use Rifled guns are ideal.

Rifled guns have many advantages. In addition to the advantages of high shooting accuracy and strong shell penetration due to the high muzzle velocity, they also have the advantages of light weight and less propellant.This is very attractive to the Planning Academy and the Executive Committee, which have always been known for their frugality.

As a reactionary academic authority on old-style artillery, Lin Shenhe's artillery configuration plan is to use Dahlgren's rifled guns with Minie-style shells.This is a front-loading rifled gun. Its appearance is characterized by drastic changes in the gun body. The front tube is small, and the part of the gun bore near the gun bore is very inflated. The shape is similar to a wine bottle, so it is also called a wine bottle gun.

The reason why the front-mounted cannon was chosen can avoid the processing of complex air-tight parts. Compared with the Armstrong-style cannon manufactured by the machinery factory, the Dahlgren cannon is cast by the Rodman method. The production process is relatively simple, and it can be used Cast iron production.The cost of materials and man-hours are much less than that of Armstrong guns.The Dahlgren cannon cast by the Rodman method can be made very large. The Americans manufactured and used this kind of artillery in large quantities during and after the Civil War, and some of them had a caliber of 16 inches.
