My German Empire

Missiles and rocket launches are very dangerous for a long time. For example, early missiles and rockets, because the technical limits used at the time, the fuel used is high corrosion and the unstable material of the explosion of the explosion, and it is slightly not paying attention to the terrible accident. Even if the future generation, the fuel fuel fuel fuel fuel of the rocket and missile is not a trouble.

During World War II, Germany's ME163 "comet" interception machine with rocket engines frequently occur frequent accidents. Different from ordinary fighters, once the fuel tank discloses, the pilots close to the cockpit of the fuel tank will be dissolved by high corrosive highly toxic fuel! Comet aircraft lost due to fuel explosion is much more than being hit by enemies.

Therefore, Yinik is not very much like a liquid fuel. "How is the research of solid propellant?" The liquid fuel accident frequently, the Second World War I wanted to change into a solid fuel, which did not have a row due to the end of the war.

The earliest solid propellant is a black powder of four in the four major inventions of China. As early as the beginning of the Tang Dynasty, around 682 AD, the "Danshan" book of "Dans" in the "Dan Jing" book is a formulation of black powder. It is a 15% charcoal as a combustion, and 75% potassium nitrate is used as an oxidant. 10% of sulfur is both a combustion and a function of bonding charcoal and potassium nitrate.

The Rockets with Black Pharmaceutical have been used as a weapon in the war in the war. This kind of rocket in the 13th century passed into the Arab countries, and later transferred to Europe.

However, the amount of black powder is low, the strength is poor, and the large number of cigarettes and solid residues are generated when burning. The solid rocket of black powder is close to the murder. Modern missiles and rockets have been difficult to find black powder.

With the development of industrial and science and technology, all kinds of solid propellants are emerging in the spring.

There are many materials that can become a propellant, and it is possible to cause continuous combustion of external force without an external oxidant, and can produce a large number of high-temperature gas molecules or solid jet during combustion. This potential has this potential. Overall, combustion is a strenuous and fast-exothermic redox reaction, so the propellant must simultaneously contain an oxidizing agent and a combustion actuated as a reducing agent.

Both oxidants and combustors are solid propellants called solid propellants. They are made into a geometric shape that meets the design requirements, cast or fill in a container in one end. When it is ignited, the chemistry of the propellant can be converted into the thermal energy of the gas, and when the engine nozzle is passed, it is partially converted into kinetic energy to form a thrust.

Dr. Kremer True. "Composite solid propulsicles are still developing, and it can be successfully developed for a year."

In fact, the solid propellant has ready, the smokeless powder used in bullet cannon, which is nitrogenation.

Nitrification cotton is a fibrous substance, which is difficult to form a fixed-shaped boustic charge, and people are mixed with a viscous nitroglyceride to make plasticizers and nitridium to form a double-based propellant. During a long period, the double-based propellant is the main raw material for the solid rocket engine.

Nitrification cotton and nitrifying glycerol itself are both ingredients of the oxidant and the composition of the combustion. Nitrification cotton is a bit rich (there are more components of the burner), and nitrifying glycerol is a bit oxygen-rich (more components of the oxidant).

It is ideal for both cooperation. However, as the engine performance requirements are increasing, this classic match can result in the need to meet the needs (the ratio is an important physical quantity that describes the performance of the rocket engine, which is defined as the unit weight propellant can bring The amount of momentum is changed. The same weight fuel, the higher the ratio, the greater the momentum can be provided.)

He hesitated, Dr. Kremer added another sentence. "Available even for this solid propellant, performance is still inferior to liquid propellants. We also work hard to improve the long-term storage technology of liquid propellants while developing solid propellants."

The thrust of the liquid propellant is large.

The advantage of solid missiles is that the flexible movement is that the throwing capacity is poor because the solid fuel is relatively low. The price of solid rockets is high, and the large-scale solid rocket is difficult to develop, and the problem of aging of solid fuel after long-term preservation is very difficult.

In general, the liquid missile is suitable for technology levels that reach a high technical indicator with a lower technical difficulty. Therefore, mostly used for early ballistic missiles, such as V2, flying legs, etc. It is also used for remote missiles and intercontinental missiles for throwing capabilities. The advantage of solid missiles is to respond quickly, and therefore often used for mobile missiles and tactical short-range missiles.

Yatik is sighful to sigh. "Use liquid fuel must pay attention to safety, do not have a hint of horses and tiger." Even if he uses the knowledge of the future generation to promote technology development, it is impossible to leap for two or three years, or have to gradually enter.

After taking it, I talked about the guidance model of the empty missile. This X-4 empty missile is different from the infrared / radar guidance method of modern empty missiles, which is guided by pilots and manually controlled. However, Single-seat fighters such as BF-109, FW-190, pilots are difficult to control the aircraft and missiles. Therefore, X-4 can only be deployed to multiple aircraft.

There are 4 large and X-shaped francs in the rear of the X-4 bodies. Among them, the top of the two magnes has a moving cartridge. The original time and space is designed to store 5,500 meters long copper-tier wires in the cartridge. Now it is changed to the fiber.

The other end connects the controller on the plane. When fighting, the pilot is like manipulating the game handle, and the remote missile is pitch and yet to fly to the target. The maximum flight speed of the missile is 1152 kilometers per hour, and the attack distance is 1500-2500 meters. This has exceeded the role of the heavy machine gun, which is enough.

The original time and space has three detonation methods: one is to trigger the letter; the second is that the pilots are manually detonated; the third is that it is very advanced at that time, known as "Kranech". Voices.

Because Germany at the time did not develop a radio near-frometry, only the insect of the insepassion is replaced.

The inductance near-flee is excited by the Doppler frequency shift principle. The Germans set their frequency to 200 Hz, which is the roar of the B-17 bomber engine. The faster activation distance is about 40 meters, starting from 7 meters, as long as the pilot guides the missile to the plane to blow up it, it is very effective.

Now the German army has been equipped with radio, and there is no need for this kind of accepted.

Janick briefly describes the principles of infrared / radar guidance to Dr. Kremer, Uu reads www.uukanshu.com Kremer Dr. He is inspired, indicating that it will immediately start research and development.

However, even in a short period of research, Jenick did not intend to put infrared / radar air missiles into this war.

The first generation of infrared empty air-to-air missile is typical products in the US AIM-9B "Rattles", Russia's K-13 and other missiles. The first generation of radar air-to-air missile typical products is the "sparrow 1" empty missile.

The first generation of air missile attacks is relatively poor, only better than the a country, and there are "missiles that" missiles are not as good as shells, and the air is still bullied. "

The second generation of the second generation of the second generation of the second generation began preparing for the troops. Among them, infrared empty missiles represent the product of the AIM-9D "Rattles", France's Matra R530, Russia's R-60T, etc. Radar guidelines have a "Sparrow 3A" (AIM-7E) missile, the British "Fire" missile.

Due to the difference in the reliability of the missile system, the US Air Force launched 589 sparrow 3 missiles in the Vietnamese battlefield, only 55 hit targets, the success probability is only 10%, while only half of the missiles can work properly.

In view of this, Jenik feels how to develop to the second generation of the second generation.

As for this war, it is enough to use this X-4 missile. Its production process is simple, and the non-skilled worker can be competent after simple training. Even if Germany, Germany, Germany, the Ruerbrickvide factory produced 1300 missiles in half a year.

Then visited the air missile, empty ship missile, anti-radiation missile, etc., then left the missile research center, returning to the palace.
