After Bao Zixuan sorted out the technical information in order, he began to check the situation in the second box, and he was pleased that the Germans were more conscientious. A box contains only one weapon technical information, even if there is room for other drawings, and it is very neatly arranged.

If you don't mess with it, you won't make a mistake at all; this once again made Bao Zixuan admire the rigorous Germans, who were about to be defeated and sorted out and buried items; and they were able to do it in the face of danger, which shows the working attitude and style of the engineers at that time.

What made Bao Zixuan feel strange was that the next two boxes were the same number. It's just that the suffix numbers are different, one is the uppercase Arabic numeral one, and the other is two. It appears that the two large boxes contain a weapon blueprint. But what kind of weapon is needed to have so many drawings, even the atomic bomb does not need to be so complicated, after all, the size of the German box is not small!

When I opened the oil-paper package, I finally knew why there were so many technical drawings, after all, this weapon was too complicated. It's so complicated that Germany only produced one piece of the country, but now this technology is completely outdated and has no use at all, but since it has been discovered, it is necessary to keep it as a souvenir.

The cannon refers to the Gustav cannon. During World War II, Führer Hitler issued an order to German engineers to design a "super cannonball that could penetrate one meter of steel, seven meters of concrete, and 30 meters of earth", which was presented to Hitler by the weapons experts of the German Friedrich Krup Arms Company

The Gustav Cannon, the largest cannon ever built, weighed 1,344 tons including the transporter, and was four stories high, 20 feet wide, and 140 feet long. Operating the Gustav Cannon is a logistics nightmare, as 3,000 soldiers working together and dedicated rails are required to carry and move the "super monster" and unleash deadly shells at the enemy.

The "Gustav cannon" has a barrel with a diameter of nearly 1 meter and a width of almost 1 meter, which can hold two shells, one high-performance explosive shell weighing 10,584 pounds and one concrete piercing shell weighing 16,540 pounds. The "Gustav cannon" could hit targets up to 29 miles away, making it a "superweapon" of its time. However, it had a fatal drawback, after every 48 shells fired, the barrel was completely damaged.

In real combat, the "Gustav cannon" fired a total of 300 shells at the city of Sevastopol, and in 1944 it fired another 30 shells at Warsaw, Poland, and it has not been used again. Because it is too bulky, it is quite cumbersome to transport, and it is easy to become the target of enemy air force bombing, this "super monster" did not bring the dying ** empire back to life in the end, on the contrary, it became a trophy of the US army in a battle, and the US soldiers then knocked this "super cannon" into scrap metal

Now that missile technology is developing rapidly, this ancient divine beast is basically useless. It's useless to build it, it seems that it can only be appreciated, or it can only be used as a technical reserve in the field of artillery, after all, this is also the largest artillery ever made by mankind, and there is no one. He is definitely the winner of the Guinness Book of Records, and it is estimated that no one will be able to break this record in the future. Even the loser will not lose the family to this aspect, mainly because no factory can take this order.

Put aside the drawings of the cannon, take pictures if you have time, forget it if you don't have time, after all, this thing is quite chicken, not even as good.

Bao Zixuan then opened the box, and at this time there was a feeling of online shopping and express delivery in the future. I knew what might be inside, but I was still very excited and excited.

The moment when the oiled paper is peeled off at one time, the drawing is revealed. Bao Zixuan rejoiced again in his heart, what he got this time is finally a little useful, although the technology has been backward, but the Black Cloud Group does not have technical reserves in this area, which can just fill the gap in this field.

The V2 rocket is a new long-range weapon, which was developed by Germany under the leadership of Dr. Weynch von Braun of the Peytimünde Research Center in World War II, and is the first large rocket missile in the world, and it is also the first ballistic missile in the world to be put into actual combat use.

The V-2 rocket was a German ballistic missile of World War II. It was the first supersonic rocket and was the forerunner of modern space launch vehicles and long-range missiles. Development began in 1936, and in 1944 it was first launched to Paris. Two days later, the attack on Britain began, with more than 1,300 launches. Belgium suffered almost the same heavy blow.

V2 is a single-stage liquid rocket with a total length of 14 meters, a weight of 13 tons, a diameter of 1.65 meters, a maximum range of 320 kilometers, an altitude of 96 kilometers, and a warhead weighing 1 ton. The V2 adopts a more advanced program and gyro dual control system, and the thrust direction is controlled by the high-temperature graphite rudder blade. The V2 realized the technical vision of the aerospace pioneer in terms of engineering technology, and played a role in the development of modern large-scale rockets. It has become an important milestone in the history of aerospace development.

This rocket bun Xuan, known as the originator of modern rockets and ballistic missiles, has long wanted to have, there is no obvious difference between missiles and rockets in technology, but one is ground-to-ground, the other is ground-to-space, as long as the directional gyroscope is adjusted, it can be controlled.

On March 29, 1945, at the railway station in Bromskilchen, Hesse, the Americans were given 10 complete V2 rockets along with mobile launch platforms, propellants and operating instructions. The V2 rockets were shipped to the port of Antwerp three days later and then to the United States, where they became the basis of American rocket technology.

In 1946, the U.S. Naval Laboratory launched a V-2 rocket to an altitude of hundreds of kilometers to observe ultraviolet rays from the sun, which was also the first time that the V-2 rocket was used in space research, which opened a new page in space science. In addition, the V-2 rocket was also used as a manned flight test vehicle and carried small animals such as monkeys into space.

At the same time, in the summer of 1945, the Soviets captured a large number of German scientists in Soviet-occupied territory, and in 1946 transported them and their family members, as well as the remaining engineering and manufacturing facilities, to the Soviet mainland for rocket development. The Soviet R-1 missile, a direct copy of the V2 rocket, was launched at the Kapustin Yar Range in 1947. The V2 rocket also became the cornerstone of Soviet cosmonautics and missile weapons.

For the human aerospace industry V2 is an unavoidable topic, why the United States and the Soviet Union can lead the world in the field of space, is not one to get Germany's top scientists, the other to get the technical data and part of the finished products of German V2 research.

Bao Zixuan believes that with his prerequisites in the aerospace field, he will not do worse than them, the only regret is that this thing cannot be easily manufactured, otherwise it is estimated that he will be launched first before it is launched.

However, it is not impossible to sort out the information and make technical reserves, after all, Yulin Institute of Technology has relevant professional courses; this is not a ready-made teaching material, you can use it when you go back and sort it out, but you still need to think carefully about who to sort out the information.

Didn't Elon Musk and Bezos both set up their own space exploration companies in later generations! Even the Chinese mainland will gradually open up to the aerospace field, and it will have the opportunity to build rockets.

Getting the V2 rocket technical information made Bao Zixuan even more motivated, after all, there are too many good things in Germany. It is estimated that the technology obtained after the boxes are opened may take him the next ten years to digest.

This was the crystallization of science and technology developed by Germany in a special context, and the world's science and technology center was in Germany at that time. Before World War II, half of the Nobel Prizes in physics were won by Germans, which shows that Germany was strong in the industrial, scientific and technological, and military fields at that time.
