Chapter 250 Naval Gun
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 the explosion of the artillery is even more It's a common occurrence.
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. 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 can be torn and twisted to this point - this is the power of fire and explosives.
"I just don't know if it's a problem with the fuse." Lin Shenhe said. There are various reasons for the explosion of artillery, and it may not be premature explosion of the shell caused by fuze failure. This 70mm artillery is an early product of the metallurgical and mechanical department. It is of relatively poor quality. It has been equipped on 8154 for a long time. After being dismantled, it was used as a test-firing artillery for a long time in the shooting range. Maybe there were cracks that they hadn't noticed.
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's the fuse. Although it was distorted by explosions and fireworks, the general result could still be seen. The specific analysis will only be known after careful disassembly in the laboratory.
The disassembly results showed that the cause of the explosion was premature firing of the firing pin caused by spring failure. Although a rifled gun was lost, Lin Shenhe finally got the result he wanted: at least, fuzes 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, the 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, and built two experimental prototype guns in the mechanical department, which were tested in several exercises.
However, the Planning Institute was not interested in this. With the usual stingy attitude of the Planning Institute, it said that the current smoothbore artillery equipment system was established in less than two years, and many artillery had been in service for less than twelve months. It would be a big deal 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 fuse 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 have spent a lot of effort, but all the benefits have been taken by the navy..." Although Lin Shenhe is not a member of the army, he has served as a company commander in the first stage, which can be regarded as a battle 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 Zhang Bolin, Ying Yu, Bai Yu, Xu Yingjie and others at the Nanhai Cafe to drink together. The reason why Xu Yingjie was invited was not only because they were 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 explosive. Although the sulfonation process only requires the use of nitric acid and sulfuric acid, the production conditions are not harsh and the yield is not bad. However, after a comprehensive evaluation, the Planning Institute concluded 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 Project 0017 at the meeting of the Planning Institute and announced that it would be "Technical reserves", 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 is self-evident what choice the planning institute, which is known for its stinginess, will make. of.
Everyone drank 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 softly. Zhang Bolin would be even more unhappy when he found out what he was about to do - tomorrow morning he was going to install artillery pieces for the navy's new warships. Zhou Ke, the project leader of the first shipbuilding and maintenance plan, invited him to go and have an on-site 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 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 Bobu. The small train to Bobu did not run at night unless he was willing to take the risk of taking a truck. There are gas street lights on the road, but they are very sparsely arranged, and you can barely see the road. However, the lights at least mark the boundaries of the road, so that you will not go off the road on a moonless night.
Mountain bikes have self-generated lights, and Lin Shenhe relies on the light of the lights to 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 veteran 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 sentry inspection and riding for another ten minutes, the figure of Project 854 finally appeared in front of him.
The 1630-class iron-ribbed wooden hull clipper-head steam-assisted sail 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 the fourth-class sailing battleships of the 18th century had a larger displacement. But in this time and space, it is an out-and-out behemoth. Although some large ships of 1,000 tons had appeared as early as the 15th century, they were few in number and rarely appeared 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 ship painted in light black is now quietly moored at the Bobu Naval Pier, and its outfitting has been basically completed. Only the final installation of the deck guns remained.
On the pier in front of the ship's hull, there is a temporary work shed that is brightly lit. Under the high light of the gas lamp, the senior engineers in charge of shipbuilding affairs, headed by Zhou Ke, are gathering together to discuss the implementation plan of 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 position arrangement 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 on multiple levels below the deck, and instead arranged all artillery on the deck. The center of gravity of the sail warship is high, and the artillery is arranged below the deck to stabilize the center of gravity. The weight of steam engines, boilers and coal bunkers is now fully capable of playing a stabilizing role in the past when artillery was placed below the deck.
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 very attractive to the Planning Institute and the Executive Committee, which are always known for their frugality.
As a reactionary academic authority on old-style artillery, Lin Shenhe's artillery configuration plan was to use Dahlgren rifled guns with Mini-type shells. This is a front-loading rifled gun. Its appearance is characterized by drastic changes in the barrel, a small front tube, and a large expansion of the barrel near the barrel. The shape is similar to a wine bottle, so it is also called a wine bottle gun.
The reason why the front-loading cannon was chosen can avoid the complex processing problems of air-locked parts. Compared with the Armstrong-style cannons that have been manufactured by the machinery factory, the Dahlgren cannon is cast using the Rodman method. The production process is relatively simple and can be used. Cast iron production. The material cost and labor hours are much saved compared to the Armstrong artillery. Dahlgren cannons cast using the Rodman method can be made very large. Americans manufactured and used a large number of such artillery pieces during and after the Civil War, some with a caliber up to 16 inches.
