After the smoke cleared and the safety whistle sounded to confirm that there was no danger of subsequent explosions, Lin Shenhe and Bai Yu poked their heads out of the bunker -- explosion accidents are not uncommon for people engaged in the weapons industry, and artillery explosions are commonplace

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

"The power of the charge is good" Bai Yu squatted down and carefully observed the blown up muzzle, the muzzle was twisted like a trumpet flower, it was hard to imagine that the hard steel could be torn and twisted to such an appearance - this was the liliang of fire explosives

"I just don't know if it's a problem with the fuze," Lin Shenhe said, there are various reasons for the explosion of the artillery, not necessarily the early explosion of the shell caused by the failure of the fuse, this 70mm gun is an early product of the metallurgical and mechanical departments, the quality is relatively inferior, it has been equipped on the 8154 for a long time, and after it is dismantled, it has been used as a shooting range for a long time

Bai Yu didn't say anything more, he looked through the wreckage carefully, and suddenly put on cotton gauze gloves and took out a twisted metal part from the still hot and white blast chamber

"Beware of ......"

"Don't get in the way, the detonator has already exploded" Although Bai Yu said this, he still carefully put the wreckage in the rattan basket

It is the fuze, although distorted by the explosion and fireworks, that the approximate results can still be seen, and the specific analysis will not be known until the laboratory has been carefully disassembled

The results of the dismantling proved that the cause of the explosion was the early firing pin caused by the failure of the springAlthough he lost a rifled gun, Lin Shenhe finally got the result he wanted: at least, the fuse made of wrought wire could be used on low-origin guns such as mortars, mortars and howitzers

In accordance with Lin Shenhe's overall jihua, the artillery should be upgraded immediately after the fuze is finalized, and the current smoothbore gun system should be changed to rifled guns - at least the equipment system of front-loading rifled guns

To this end, he had already drawn up drawings of several types of army artillery and had built two experimental prototypes in the mechanical department, which were tested during several exercises

However, the Planning Institute was not interested in this, and said with the usual stingy attitude of the Planning Institute that the current smoothbore artillery equipment system had been established for less than two years, and many artillery pieces had been in service for less than 12 months, and it would be a great waste to upgrade them immediately, so they did not agree to upgrade the army's existing artillery system

Therefore, the biggest beneficiary of the grenade fuse is the navy - all rifled guns are equipped with the navy at present, and all the naval guns equipped according to the Jihua, 854 and 901 projects are rifled guns

Zhang Bolin hung his head frustratedly: "You have spent a lot of effort, and the benefits have all been taken up by the navy, ......" Although Lin Shenhe is not a member of the army, he has also been a company commander for a stage, and he has eaten a pot of rice with the army, so Zhang Bolin still regards him as "his own person"

"Don't get in the way, when the engine is finished, it will naturally be the time for the riot army and the riot 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 in the Nanhai Cafe, and invited Zhang Bolin, Ying Yu, Bai Yu and Xu Yingjie and others to drink together The reason why they invited Xu Yingjie was not only because they are now colleagues, but also because they comforted their opponents: the 0017 project presided over by Xu Yingjie suffered the same fate as the type artillery - it was shelved

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, but after a comprehensive evaluation by the Planning Institute, it is believed that the immediate production of picric acid requires the construction of a workshop and a full set of production equipment

"In the current state of quasi-war, the continuity and convenience of production should be considered first and foremost, rather than rushing to use the jishu process," Wu De mercilessly shot the 0017 project at a meeting of the Planning Institute, announcing that it would be mass-produced again as a "jishu reserve" and other "when the time is ripe".

From the very beginning, Lin Shenhe achieved such a result - although high-density black powder is certainly not as good as picric acid in terms of performance, it is better than low cost, and it is self-evident what choice the planning institute known for its slamming will make

Everyone drank nonsense in the café for a while, and when they were half-drunk, Lin Shenhe quietly settled the account and slipped out

"Lao Xu, I'm sorry, and Berlin," Lin Shenhe whispered, he was about to do something, let Zhang Bolin know, he would definitely be unhappy - tomorrow morning, he was going to install artillery for the navy's warships, and Zhou Ke, the project leader of the first shipbuilding and maintenance jihua, asked him to go to the field to inspect it at night

Lin Shenhe returned to the apartment, and Shenye had already prepared his mountain bike - this was allocated to the patriarch for personal use, although many people liked the 28 bars, but Lin Shenhe still preferred to ride a comfortable mountain bike

"Be careful all the way" Under the advice of his sister, Lin Shenhe rode quickly on the highway to Bopu, and the small train leading to Bopu at night is not open, unless he is willing to take the risk of taking a truck, there are gas street lights on the road, but the layout is quite sparse, and he can only barely see the road, but the lights at least mark the boundaries of the road, so as not to go out of the road on a moonless night

Mountain bikes have their own headlights that generate electricity, and it is by relying on the light of the headlights that Lin Shenhe can confidently and boldly gallop on the highway - of course, there will be no pedestrians and vehicles on this road now, and the area along the road has been upgraded to a green zone, and there will be no danger for the elders to walk alone

On summer nights, the breeze is cool, and it is very comfortable to ride on the road, but the headlights attract a large number of flying insects, flying around his bicycle, which makes him very annoying

In order to arrive as soon as possible, Lin Shenhe did not enter Bopu Town, but went directly to the naval base by branch road

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

The 1630 class iron-ribbed wood-hulled shear head steam-assisted powered sail cruiser is not a huge warship, its standard displacement is only 1160 tons, and it is 70 meters long. It is 9.9 meters wide and in the old time and space, even the displacement of the fourth-class sail battleship in the 18th century is larger than it, but in this time and space, it is an out-and-out behemoth, although as early as the 15th century, there have been some large ships of 1,000 tons, but the number is very small, and it rarely appears at sea, when its hull is launched at the height, it has attracted a large number of onlookers - although they have become accustomed to seeing 10,000-ton iron ships, but an imaginary big ship is built under their noses, It's still very dramatic

The light-black painted ship is now quietly moored at the Bopu Naval Pier, and the outfitting has been almost completed, and only Zuihou's deck guns are installed

On the dock in front of the hull, there is a temporary shed that is brightly lit, and under the high light of the gas lamp, the veteran engineers in charge of shipbuilding affairs led by Zhou Ke are gathering together to discuss the implementation plan of the 1630-class Zuihou outfitting project

The gun arrangement scheme of the 854 modification completely abandoned the orientation of the multi-deck gun emplacements - although many people were very infatuated with the spectacular scene of dozens of guns firing sequentially on the sail battleships in the 18th ~ 19th centuries, but such a gun emplacement arrangement was inappropriate for the structure of the hybrid warships manufactured by Lingao - and with the scientific and technological capabilities and industrial level mastered by the Senate, there was no need to copy the sail battleships,

The 1630 class completely abandoned the practice of arranging gun emplacements in multiple layers below the deck, and all changed to the arrangement of guns on the deck, the center of gravity of the sail battleship was high, and the guns were arranged below the deck with a stable center of gravity

Since the guns were placed on the deck, the number of guns would not be too large, and the power of the guns had to be large enough not only to be able to deal with the largest European ships in naval battles, with fast firing, but also to take into account the need for future artillery land bombardment to support army operations

To meet this requirement, the various smoothbore guns currently equipped with Navy ships, from 12-pounder cannons to 32-pounder Carons, including the heaviest 68-pounder Caron guns in the Navy at present, are not sufficient - rifled guns are the ideal choice

The advantages of rifled guns are many, in addition to the advantages of high shooting accuracy and strong penetration of shells brought about by the muzzle height, there are also the advantages of light weight and less propellant used, which is very attractive to the Planning Institute and the Executive Committee, which have always been known for their frugality

As a reactionary academic authority on the old artillery, Lin Shenhe proposed that the artillery configuration scheme was to choose the Dahlgren rifled gun, with the Mini type shell, which is a kind of front-loading rifled gun, the shape is characterized by drastic changes in the gun body, the front body tube is small, the gun chamber part near the gun chamber part is very large, the shape is similar to a wine bottle, so it is also called a wine bottle cannon

The reason why the front-loading gun can avoid the processing problem of complex air-tight parts, compared to the Armstrong guns that the machine factory once manufactured, the Dahlgren gun was cast by the Rodman method, the production process was relatively simple, and the cost of materials and man-hours could be used to produce cast iron compared to the Armstrong gun, and the Dahlgren gun cast by the Rodman method could be made very large, and the Americans made and used this kind of artillery in large quantities during and after the Civil War, some of which reached 16 inches in caliber (to be continued)
