Chapter 301 V-2 Missile

Weiner von Braun was born in Germany in 1912. Under the influence of his mother, an excellent amateur astronomer, Braun stepped into the field of spaceflight.

He graduated from Charlottenburg Institute of Technology in 1932 with a bachelor's degree in aerospace engineering.

In 1934, the A-2 rocket was developed, and the rocket was successfully tested at the test site near Kummersdorf.

In 1936, he led the design of the A-4 rocket program, the missile later named the V-2.

Throughout World War II, he was a well-known German rocket expert and played a key role in the birth of the V-1 and V-2 rockets.

After the end of World War II, the Soviet Union obtained German rocket materials, while Braun and his scientific research team surrendered to the United States, and the two countries each started a new space program based on Germany.

Braun, on the other hand, joined the American nationality and became the father of aerospace in the United States. Almost all aerospace programs in the United States were led by Braun, such as the famous Apollo moon landing program, such as the American space shuttle. Credit to Braun. And now, Braun is getting into shape earlier than in history.

In Europe, it is difficult to find a suitable launch site, but in the vast and boundless Libyan desert, it is even easier to study rockets!

The sky was already bright. This was the second day Hitler came to Libya. He was near the base. He watched Braun's experiment with great interest.

Last night, Braun didn't explain too much to Hitler. Anyway, Hitler didn't know that much professional knowledge at all, but Cyric, a general who had nothing to do with aerospace, put forward many insights that made Braun. En very inspired.

Now, Braun has completed the full development of the V-2 rocket!

To develop a missile, the most important thing is the engine! Braun's missile engine was designed by him himself. This engine is almost one person tall, and the entire missile looks quite smooth in appearance and is 14 meters high.

Standing on the launch pad is the missile that Braun is going to test this time. At this time, the boom on the side is busy, and someone is refueling the rocket.

"Our rockets use alcohol and liquid oxygen," Braun said. "At the base here, there is a workshop dedicated to making alcohol and liquid oxygen."

The base is very large and has been continuously developed over the years. Now, almost half of the base is a workshop for rockets.

"Dr. Braun, I don't know if you have ever thought about it. The combination of alcohol and liquid oxygen is actually not very suitable for rockets." Cyric said involuntarily.

Last night, Braun introduced that the total weight of this rocket is 14 tons, which contains 5 tons of liquid oxygen and 3.5 tons of alcohol. It can generate a thrust of 260 kN, with a maximum range of 320 kilometers, a flight time of about 320 seconds, and a hit accuracy of 5,000 meters.

This kind of rocket is already quite advanced. It can be said that it has reached the level of the historical V-2 missile a few years in advance. However, Cyric has now raised a very sharp question, propellant Not suitable!

First of all, it is the problem of liquid oxygen, which needs to be stored at low temperature! The storage at minus 183 degrees is the biggest problem when using it.

Looking at it now, it is filling liquid oxygen, and it can be seen that a thick layer of frost has formed on the outside of the filling pipe. At the same time, the filling personnel are also very dangerous.

On the other hand, the cost of alcohol is very low, but this thing burns low energy. Looking at the future, almost no alcohol is used as fuel.

If liquid oxygen is used, then simply use liquid hydrogen and directly engage in liquid hydrogen and liquid oxygen engines, and this is only used in the highest stage of the rocket, with the highest specific impulse and the most technical difficulty.

At the next level, the more commonly used one is the liquid oxygen kerosene engine. Unfortunately, the difficulty of this thing is not ordinary, only Lao Maozi has conquered it, and that will be a matter of many years.

So, look for more common ones.

what fuel?

Of course, unbalanced dimethyl hydrazine and nitrous oxide, or nitric acid!

Dimethyl hydrazine, although highly toxic and carcinogenic, can be stored at room temperature after all. Together with nitrous oxide, it is a common fuel for future rockets! As soon as the two come into contact, you don't need to ignite, and you can start it directly!

So, when Braun asked for advice on what was more appropriate, Cyric, of course, directly said this common plan.

"You don't need to store at low temperature, just wear a gas mask when refilling. I think my plan is more suitable. If you think it's feasible, you might as well try it." Cyric said.

In fact, of course Braun also felt that the liquid oxygen solution was not suitable. The preparation before each launch of this kind of rocket is not only dangerous, but also very complicated. If there is room temperature propellant, it should be much easier, but he has been Just didn't think about it.

Unbalanced dimethyl hydrazine, nitrous oxide? Well, it seems that could be the focus of the next aspect.

"In addition to the engine, another key point of improvement is the inertial navigation system." Cyric continued: "Our domestic electronic technology is constantly improving, and our advanced electronic technology is used to transform our inertial navigation system. , so that this missile has higher accuracy."

Historically, Hitler attached great importance to V-2 missiles. This is simply a big killer tailored for the United Kingdom. During World War II, Germany launched thousands of V-2 missiles to the United Kingdom, of which only 7%. More than ten of them fell within 30 kilometers around the target, and of these, about 40 percent fell within 10 kilometers.

What is this concept? Almost no one hits the target! Therefore, although Germany looks aggressive, in fact, this missile is useless for birds, the main reason is that the accuracy is too poor!

Unless it is equipped with a nuclear warhead, it can only be used to intimidate. Of course, in a certain sense, it has also achieved this effect. The United Kingdom has nothing to do with this kind of missile, and they cannot intercept it.

This contributed to the situation in which countries frantically developed missiles after World War II.

Improve accuracy! Let this missile really be useful!

Braun quite agrees with Cyric's proposal, and Cyric is right!

"The raise is complete, it can be fired!" At this moment, an assistant said.

At this time, there are not so many programs, start the gyro, the target data is set before, and now, it can be ignited!

ignition!

With Braun's order, the bottom of the black missile burst into flames!

The turbine blew the fuel and oxidant into the engine inside, ignited, and the high temperature of more than 2,000 degrees spewed out from the back!

In the blazing flames, the missile took off from the launch pad on the ground! Hitler's eyes, watching the rise of the missile, as if his empire was taking off!
