Chapter 32: A full-scale model of the Vulcan cannon

At this party, everyone was very drunk! First, the preparations for the Stockholm International Defense Exhibition have indeed been very smooth, with more than 300 exhibitors and almost all of the world's famous arms dealers, which is also a big event for Sweden, which is holding an international defense exhibition for the first time. Second, the wine is indeed a good wine, Bordeaux wine is famous all over the world, it has a smooth and delicate taste, a variety of styles, and has the reputation of "French wine queen", how can everyone be polite in the face of such a good wine.

In the end, Philip didn't even know how to walk back.

The next morning, when it was dawn, Philip and Anna opened their eyes almost at the same time, still embraced while the clothes had not been thrown somewhere. Philip only felt that he had a beautiful dream last night, could it be that he and Anna had ......

Anna remembered that she had been drunk the previous day, and then she followed Philip back to his dormitory in a daze, and although she had done so willingly, she seemed to be unable to remember anything about the previous night.

The two looked at each other, looking for their own shadows from each other's eyes, and the thick affection flowed quietly between the two, slowly surrounding the two.

Happiness is the only feeling in Anna's heart. Anna is a very simple girl, and the moment she opens her eyes in the morning, she can see her lover sleeping next to her, which can make her feel very happy.

"Honey, don't you want to get up yet?" Philip looked at Anna embarrassedly, he didn't expect such a thing to happen, but since he already took possession of someone's family, he had to be responsible for someone's family. Philip didn't want to interrupt the feeling of happiness, but he had to interrupt it, the two of them couldn't stay in bed all the time.

"Will you be good to me for the rest of your life, Philip?" Anna looked at Philip shyly, then sat up slowly, looking happy.

Philip looked at Anna lovingly and said, "Anna, don't worry! I, Philip, swear I will love you for the rest of my life, or else the sky will thunder! ”

Anna hurriedly stretched out her arm like a jade couple, and her slender jade fingers pressed on Philip's lips at once, with a hint of playfulness in her charm: "Philip, I believe in you!" You're my king, Anna feels so happy, can you kiss me again? ”

Philip looked at the affectionate beauty in front of him, and couldn't help but kiss Anna's bright red cherry lips......

With less than a month to go before the opening of the Stockholm International Defense Exhibition, Bofors' exhibition preparation team is getting busier. In addition to being busy with the exhibition, Philip also had to hurry up to make the design instructions and full-scale model of the Vulcan machine gun, which was a package ticket in front of the boss Carl, if he couldn't complete the task, wouldn't he be a slap in the face?

As the saying goes, men and women are not tired of working together. Fortunately, with Anna, a stunning beauty, Philip didn't feel too tired.

The design specification of the Vulcan machine gun should weigh the trade-offs and unify the contradictions according to the tactical and technical requirements and the technical and production possibilities, and put forward the most appropriate and optimal design plan that meets the overall requirements under the current conditions. Based on this, the types of artillery components and their compositions are drawn up, and the design of each component is organized and guided to realize the plan, and the contradictions are coordinated to design the entire mobile weapon system. Finally, the design is modified after trial production and test until the product is finalized.

Artillery design needs to be designed with the right size and weight, simple and reliable construction to achieve the highest possible performance in order to achieve the maximum impact on the battlefield in the future.

The overall design of the artillery is a big concept, in terms of the design scope is large and small, any product involves the overall design idea, for a part, how to select the main view, how many views are needed, what kind of section is needed, what materials are needed, what heat treatment methods are needed, how to mark, what tolerances and surface requirements are selected, etc., which virtually shows a kind of overall design idea. For example, as the caliber of the shell increases, the mass of the cannon and the shell will increase in the relationship of d3, and the ammunition base will decrease accordingly, so it is necessary to accurately calculate the weight of the cannon and the shell according to the tactical requirements. In particular, the Vulcan machine gun has a rate of fire of up to five or six thousand rounds per minute, and the consumption of ammunition is even more staggering.

Under the condition of a certain length of the gun body, the power of small-caliber armor-piercing shells is proportional to the caliber d. If D is more than 100mm, the power is gradually proportional to the 1/2 power of D, so increasing the caliber may not outweigh the losses. Therefore, for striking the enemy's armored fighters, small-caliber guns are also very suitable.

When the design specification is completed, it is necessary to make proofs, and make a full-scale model to verify whether the design of each component is reasonable and whether the overall design meets the requirements, which is a common practice in the design of weapons in later generations.

In order to make a model of the Vulcan cannon, Philip went to the workshop every day to mingle with the workers, work together, and discuss processing methods together. You must know that Philip himself has been a skilled worker in the Krupp Arsenal for several years, and he is also proficient in machining technology, which makes the workers of the Bofors Arsenal also impressed. Originally, in their eyes, those weapons designers, especially the chief engineer of the company, were high-minded, and it was the first time they had seen a designer like Philip who was close to the workers.

Even the company's deputy chief engineer personally went to work in the workshop, and these workers naturally could not be left behind Philip, and they took the initiative to take on the task of processing full-scale model parts, and in this case, the full-scale model of the Vulcan machine gun was finally made a week before the start of the Stockholm International Defense Exhibition.

When Philip screwed the last screw, the box-shaped turret, which was nearly 2 meters high, 2.5 meters wide and 2 meters thick, was complete. In the middle of the turret are the barrels of 7 30-mm turn-tube guns, on the left is the gunner's operating compartment, and on the right is the ammunition room. The base of the turret is mounted on a circular bezel, which allows the gunner to manually rotate the turret by means of hydraulics, as well as to control the pitch angle of the barrel. ‘

The design specification also clearly reads: Vulcan machine gun, using the Gatling principle, is a 7-barreled 30 mm caliber turn-tube gun, with a maximum firing range of 5,000 meters, a maximum rate of fire of 5,000 rounds per minute, 1,000 rounds of ammunition, a total weight of 4,500 kg of turret, and a high and low firing range of minus 10 degrees to plus 90 degrees, that is, it can shoot vertically upward, and can use a variety of shells such as armor-piercing shells, armor-piercing shells and high-explosive shells, and has a strong destructive force against enemy fighters, bombers, and armored vehicles.
