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 those engaged in the weapons industry, and artillery explosions are even more serious.
It's a common occurrence.
The two men 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. The various parts were twisted and looked very miserable.
"The power of the new charge is pretty good." Bai Yu squatted down and carefully observed the blown muzzle. The muzzle was twisted like a morning glory. It's hard to imagine that hard steel could be torn and twisted like this - this
It's the power of fire.
"I just don't know if it's a problem with the fuze." Lin Shenhe said. There are many reasons for the explosion of the artillery, and it may not be the early explosion of the shell caused by the failure of the fuze. This 70mm artillery is an early product of the metallurgical and mechanical department.
The quality was relatively poor. It had been equipped on 8154 for a long time. After being dismantled, it was used as a shooting range for long-term test firing of artillery. Maybe there were cracks that they had not discovered.
Bai Yu didn't speak anymore. He carefully looked through the wreckage, suddenly put on cotton gauze gloves, and took out a twisted metal part from the exploded gun barrel that was still hot and steaming.
"Be careful..."
"It's okay, the detonator has exploded a long time ago." Although Bai Yu said this, he still carefully put the remains into the rattan basket.
It is the fuse. Although it was distorted by the explosion 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 the disassembly proved that the cause of the explosion was the premature firing of the firing pin caused by the failure of the spring. Although a rifled gun was lost, Lin Shenhe finally got the result he wanted: at least, the fuze made of wrought iron wire could be used
On low muzzle velocity artillery such as mortars, mortars and howitzers.
According to Lin Shenhe's overall plan, an artillery upgrade plan should be carried out immediately after the new fuze is finalized, from the current smoothbore gun system to a rifled gun - at least the equipment system of a front-loading rifled gun.
To this end, he had already drawn several drawings of new army artillery. He also manufactured two experimental prototype guns in the mechanical department and tested them in several exercises.
However, the Planning Institute is not interested in this. According to the usual stingy attitude of the Planning Institute, the current smoothbore artillery equipment system has only been established for less than two years, and many artillery have been in service for less than 12 months. It is huge to upgrade them immediately.
It is wasteful and therefore does 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, all naval guns equipped in Project 854 and Project 901 are rifled guns.
Zhang Bolin was dejected: "You have spent a lot of effort, but all the benefits have been taken up by the navy..." Although Lin Shenhe is not a member of the army, he has served as a company commander in the first stage, so he has suffered a lot with the army.
Rice in one pot. So Zhang Bolin still regards him as "one of his own".
"It's okay, after the engine is finished, it will naturally be time to attack the army and the artillery." Lin Shenhe comforted him, "How about it, do you want to go to the Nanhai Cafe for a drink together in the evening?"
In the evening, Lin Shenhe hosted the Nanhai Cafe and invited Zhang Bolin, Ying Yu, Bai Yu, Xu Yingjie and others to drink together. The reason why he invited Xu Yingjie was not only because they are now colleagues, but also to comfort his opponents: The 0017 project chaired by Xu Yingjie suffered the same fate as the new artillery - it was shelved.
The trial production of picric acid was very successful. Xu Yingjie used the phenol accumulated in coal coking production and used the sulfonation process to successfully produce picric acid**. Although the sulfonation process only requires the use of nitric acid and sulfuric acid, the production conditions are not harsh. , the production rate is pretty good. However, after a comprehensive evaluation, the Planning Institute believes that the immediate production of picric acid requires the construction of a new workshop and the manufacture of a full set of production equipment.
"In the current quasi-war state, we must first consider the continuity and convenience of production, rather than rushing to use new technologies and new processes." Wu De ruthlessly shot down the 0017 project at the meeting of the Planning Academy and announced that it would be "Technical reserve", waiting for "the time is right" before mass production.
From the beginning, Lin Shenhe foresaw such a result - although high-density black gunpowder is definitely not as good as picric acid in terms of performance, it is better because of its low cost. It goes without saying what choice the planning institute, which is known for being stingy, will make. metaphorical.
Everyone drank wildly in the cafe for a while, and until they were half drunk, Lin Shenhe quietly paid the bill and slipped out.
"I'm sorry, Old Xu. And Berlin." Lin Shenhe said in a low voice. Zhang Bolin would be even more upset if he found out what he was about to do - tomorrow morning he would install artillery for the navy's new warship. Zhou Ke, the project leader of the first shipbuilding maintenance plan, asked him to go to the site for an inspection in the evening.
When Lin Shenhe returned to the apartment, Shenye had already prepared his mountain bike - it was allocated to the elders for personal use. Although many people like the 28-bar, Lin Shenhe would rather ride a more comfortable mountain bike. .
"Be careful along the way." Following his sister's instructions, Lin Shenhe quickly rode on the road to Bopu. The small train to Bopu did not run at night unless he was willing to take the risk of taking a truck. There was gas on the road. The street lights are very sparsely arranged, so you can barely see the road. But the lights at least mark the boundaries of the road, so you won't have to walk off the road on a moonless night.
Mountain bikes have self-generated lights, and it is by the light of the lights that Lin Shenhe can safely and boldly speed on the road - of course, there are no pedestrians or vehicles on this road now. Moreover, The area along the road has been upgraded to a green zone, so there is no danger for the elders to walk alone.
On a summer night, there was a cool breeze, and it was very comfortable to ride a bicycle on the road. However, the headlights attracted a large number of flying insects, which flew around his bicycle, which annoyed him.
In order to arrive as soon as possible, Lin Shenhe did not enter Bobu Town, but took a branch road directly to the naval base.
After passing the inspection by the sentry and riding for another ten minutes, the figure of Project 854 finally appeared in front of him.
The 1630-class iron-ribbed wooden hull scissor-head steam-assisted sailing cruiser is not a huge battleship. Its standard displacement is only 1160 tons, 70 meters long, and 9.9 meters wide. In the old time and space, even a fourth-class sailing battleship in the 18th century was The displacement is also larger than it. But in this time and space, it is an out-and-out behemoth. Although some large ships of 1,000 tons have appeared as early as the 15th century, they are very few in number and rarely appear on the sea. When its hull was launched into the water, it attracted the attention of many people. Although they were used to seeing large iron ships of 10,000 tons, it was still extremely shocking that an unimaginable large ship was built right under their eyes. Dramatic.
The light black-painted ship is now quietly moored at the Bobu Naval Pier, and its outfitting has been basically completed. Only the final installation of the deck artillery remains.
On the pier in front of the ship's hull, there was a temporary work shed that was brightly lit. Under the high light of the gas lamp, the veteran engineers in charge of shipbuilding affairs, headed by Zhou Ke, were gathering together to discuss the implementation plan for the final outfitting project of the 1630 class.
The artillery layout plan of the 854 modification completely abandoned the position of the multi-deck gun emplacements. Although many people are obsessed with the spectacular scene of dozens of artillery firing in sequence on the sailing battleships of the 18th and 19th centuries, for the hybrid power manufactured by Lingao
Such a gun emplacement is inappropriate for the structure of the battleship - and with the technological capabilities and industrial level mastered by the Senate, there is no need to copy the sailing battleship.
Level 1630 completely abandoned the practice of arranging gun emplacements in multiple layers below the deck, and instead arranged all artillery on the deck. The center of gravity of the sailing battleship is high, and the artillery is arranged below the deck to stabilize the center of gravity. Now the weight of the steam engine, boiler and coal bunker
It can fully play the stabilizing role of artillery placed under the deck in the past.
Since 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, but it must also take into account the future shelling of land to support army operations.
needs.
To meet such requirements, the various smoothbore guns currently equipped on naval ships: from 12-pound cannons to 32-pound carronades, including the heaviest 68-pound carronade cannon among the current naval guns, are difficult to meet - adopting
Rifled guns are the ideal choice.
Rifled guns have many advantages. In addition to the high shooting accuracy due to the high muzzle velocity and the strong penetrating power of the shells, they also have the advantages of being light in weight and using less propellant. This is of great benefit to the Planning Institute, which has always been known for its frugality.
and the executive committee are very attractive.
As a reactionary academic authority on old-style artillery, Lin Shenhe's artillery configuration plan is to use Dahlgren rifled cannons with Minie-type shells. This is a front-loading rifled cannon. Its appearance is characterized by drastic changes in the gun body and a small precursor tube.
, the part near the barrel of the barrel expands greatly, and its shape resembles a wine bottle, so it is also called a wine bottle cannon.
The reason why the front-loading gun was chosen can avoid the complex processing problems of air-locked parts. Compared with the Armstrong-style guns that were manufactured by the machinery factory, the Dahlgren gun is cast using the Rodman method. The production process is relatively simple and can be used.
Cast iron production, material costs and labor hours are much less expensive than Armstrong cannons. Dahlgren cannons cast using the Rodman method can be made very large. Americans manufactured and used a large number of such cannons during and after the Civil War.
, some diameters reach 16 inches.
