Messerschmidt and Karl said in unison: "Good! Philip couldn't help but laugh.

Carl suddenly sighed: "Philip, since you left, there has been no breakthrough in our Bofors, although the production of assault rifles is in full swing, and mountain artillery and howitzers are also okay, but I still feel that there is still no product that can make our company's reputation!" ”

Karl was right, Philip thought. You must know that any arms company must have one or two representative works that can be used, and of course assault rifles are the same. However, the rifle is only a low-tech product, and it won't be long before other arms companies will copy the assault rifle. Only sophisticated and large weapons such as large-caliber artillery, tanks, fighter jets, bombers, and aircraft carriers will become a unique representative product of a company. For example, Dassault in France is famous for its Mirage series of fighters; Germany's Krupp is famous for its large-caliber artillery; The American company Lockheed is also famous for its fighters and bombers.

Philip laughed, "Mr. Karl, you are not satisfied! Now Bofors' business is thriving, and in addition to assault rifles, small-caliber guns to large-caliber guns are not bad. Do you really want to build tanks and planes? ”

Carl laughed, "Isn't that okay?" Now we are all members of the Dragon Soul Ordnance Complex, and if your aircraft manufacturing is too busy in the future, Bofors should also share a little production pressure. However, the most troublesome thing at present is the development of the Vulcan cannon. In addition, the development of 40 mm caliber anti-aircraft guns also encountered some technical difficulties, and we were a little at a loss! ”

Messerschmidt interjected: "In that case, let's go to the Bofors factory together, and let Philip, the chairman of the Dragon Soul Ordnance Complex, solve problems for the members!" ”

Karl said, "That's what I mean! It's up to Philip. Honestly, I'm sure you can help us solve the puzzle. ”

Philip smiled bitterly: "It seems that it is not easy for me to be the chairman of the board, it has only been less than an hour since I took office, and I have to go deep into the front line to do coolies." Let's go tomorrow, how about it? ”

Carl smiled, "Okay, I'll send a car to pick you two up tomorrow morning!" ”

Karl and his secretary then said goodbye to Philip and Messerschmidt and left the hotel. Philip looked at the time, and it was almost twelve o'clock. Before they knew it, the three of them discussed for hours, and they didn't even notice the passage of time.

Philip lay on the bed and couldn't sleep for a long time. Now the Ordnance Industrial Complex has been formed, which means that it is one step closer to the dream, and tomorrow to get to the Bofors plant, I'm afraid it will take another two or three days. Although Bofors was later known for its small-caliber guns and mountain guns, especially the 40mm naval guns, the Vulcan Cannon would make Bofors a different from other arms dealers known for its artillery, and it would have a greater significance than the 40mm guns that were widely used later.

In war, it is rare for the armies of both sides to be formally equipped with the same weapons, except for the temporary use of captured weapons. There was one exception, the Swedish 40-mm Bofors L/60 anti-aircraft gun, which was widely used by both the Allies and the Axis powers and was considered a standard anti-aircraft weapon. Since its birth in the 30s of the 20th century, the 40mm Bofors anti-aircraft gun has been exported, licensed, copied or improved in large quantities, thus becoming the most widely used anti-aircraft gun in World War II. This is history that Philip has known for a long time.

The first to order the M36 40mm Bofors anti-aircraft gun were the Polish Navy, the Austrian Army and the Belgian Army, all of which were purchased in very small quantities. In 1935, Poland and Hungary received the right to license the production of the M36 type 40-mm Bofors anti-aircraft gun, which began to be manufactured in their countries. By 1936, the number of M36 40mm Bofors guns began to increase, and new customers included the British and Dutch East Indies. Hungary is the country that manufactures the largest number of 40-mm Bofors anti-aircraft guns after obtaining a concession for production. Its production was mainly carried out by the factories of the Hungarian Ministry of Railways, which produced at least 767 doors before the war.

The 40mm Bofors anti-aircraft gun is the most equipped and widely used medium-caliber anti-aircraft gun in World War II. The production of 40-mm Bofors anti-aircraft guns originating from the Swedish company Bofors and licensed in other countries, copied and improved is incalculable. From the ice-covered battlefields of the Eastern Front in Europe to the scorching deserts of North Africa, from the land battlefields of Europe, Asia, and Africa to the vast Atlantic and Pacific seas, from the army's towed field antiaircraft guns, self-propelled antiaircraft guns, to naval ship-based antiaircraft guns, and even air force guns, the 40-mm Bofors anti-aircraft guns appeared in various models at the same time in the Nazi camp and the anti-fascist Allied camp under the banner of 10,000 characters, becoming the most trusted kind of small and medium-caliber antiaircraft guns by the armies of the warring sides in World War II.

The Vulcan cannon is a turn-tube weapon, which is composed of a movement box, a machine core, a gun barrel, a gun box, a bomb feeder, a buffer and an assembly, and the gun box is fixed on the gun carriage through two fulcrums at the front and rear. The movement box and a plurality of gun barrels are supported in the gun box through the front and rear bearings, the bomb feeder is fixed above the gun box, the hydraulic motor housing is connected with the tail of the gun box, the rotor is connected with the rear of the core box through the spline shaft, and the spline shaft is used as the intermediate element to transmit torque.

The working principle of the Vulcan cannon is that after the core box and the barrel group are driven and rotated by the hydraulic motor or motor, the gear on the tail of the core box will then drive the gear of the ammunition feeder to rotate, and when the clutch on the bullet feeding machine is in a closed state, the bullet wheel will be pulled, and the chain will be removed under the action of the chain removal mechanism. The shell is pulled into the gripper of each machine core in turn, and the machine core is pushed into the chamber under the action of the spiral groove in the gun box, locked under the action of the locking cam, and the shell is fired after the locking, and the actions such as unlocking, shelling, and shell throwing are completed in turn after the cannon is ejected from the chamber. The shell throwing action is completed by the shell throwing guide of the shell throwing beam fixed above the gun box. After the core extracts the shell, the cartridge shell is removed from the gripper of the machine core by using the relative rotation relative to the shell throwing beam, and the cannon body is thrown out along the curved surface of the shell throwing plate, and the shell box rotates to fire the shell equal to the number of barrels at the same position in turn, and the rate of fire of the Vulcan cannon can be controlled by adjusting the speed of the barrel.

It's complicated, but the shells are fired as fast as meteors. Of course, many of these key technologies need to be overcome one by one, such as the locking mechanism should not only have high strength and long life, but also reduce the weight as much as possible, and also have a reliable insurance mechanism to ensure that the shell cannot be fired when the locking is not locked or the locking is incomplete; The contact mode between the locking mechanism and the working surface of the core guide plate and the spiral groove of the gun box should reduce the power consumption of external energy as much as possible, and the bullet grabbing part of the locking mechanism should have a large area of ammunition. In addition, the design and manufacture of the clutch of the intake mechanism is also a key technology.

In short, the Vulcan cannon has a small recoil, a high probability of damage to the target, a long life, and high reliability, but it is much more complex than ordinary rapid-fire guns in terms of design and manufacturing.
