My German Empire

Just in the city of Washington, when I was blown up a beautiful fireball, I was a missile experimental base in Germany.

"boom!"

With a loud noise, a giant "swimming pool" stimulated the water column, and the scientific researchers in the departure shook their heads. "It failed."

The research project here is a submerged missile. When the original time and space, the development of the sub-missile, the mature design of the land tactical ballistic missile is selected, so the attempts of the two countries on the lace ballistic missile are the way to launch the ship's bullets, using the water launch. the way. That is, the submarine needs to be floated to the water while launch, and then ignites the missile after the finishing process is raised. The submarine throughout the launch is exposed to the surface. This approach is not concealed in actual combat, so Jenik has directly skipped this step, and it is necessary to develop submerged missiles that can be launched underwater.

Just the submerged missile is the largest technical difficulty in all missiles, no one; what is big? There are many countries with submarines and missile technologies in the later generations. There are only five countries with the lap ballistic missile technology (more than nine countries with nuclear weapons).

And its difficulty is multifaceted, multi-level.

The first difficulty is the carrier of the missile, submarine.

Submarines must not be ordinary submarines, limited to volume and power, etc., and want to achieve strong motion, far range, and large-scale basic requirements, in line with these foundations. Nuclear submarine. As the heavyweight, nuclear submarine has only five frequent countries, but it is impossible to know that most of this country is hard. On the other hand, ordinary nuclear submarines only meet the basic requirements of missiles, and want to complete the missile launch underwater, the ordinary nuclear submarine must be improved, like increasing the amount, eliminating the back and reduced noise. This increases certain difficulties on the basis of ordinary nuclear submarine.

If you have a nuclear submarine with missile, it is the missile.

Missiles naturally can't be ordinary roadbed missiles, to make missiles from water, and enter air, and work in two different media. This step is the shortest time, especially in the moment of breaking the surface, is calculated in seconds, but is the key to the success or failure of the irradiation missile.

Because the density of water is 800 times the air, flying in the water and air, the object is completely different. For the simplest example, the bullet can stabilize the flying in the air, but the bullets are in water, and they will instantly lose stability, and they can only advance the short distance. And the arrow bomb used by the underwater firearms is straight in the underwater ballistic, once used on the shore, it will fly. Therefore, the submerged missile must be satisfied in the water and air in the air.

If it happens to have a nuclear submarine and a subtile ballistic missile with missile, the launching method of the submerged ballistic missile is the top priority. The subsequent sub-irradiation missile is different from the ignition stage, which is roughly divided into three ways.

The first, the missile is directly ignited within the launch guide; the second, the missile rolled out the launcher, leaving the submarine from the underwater ignition; third, the missile is emitted out of the water surface, ignition in the air.

And these three methods have advantages and disadvantages.

The Soviet Union / Russia has adopted the first method. In the launch, you must insert fresh water from the dedicated water storage container. When the insert is similar to the external pressure, open the emitter cover, and then the missile liquid engine is ignited, and the self-thrust tube of the missile is used to form one in the tail. The gas impact force generated during high pressure cavity is buffered.

Using such a "wet" emission helps solve the problem that the liquid rocket engine inherently need to perform a certain time pre-cooling operation, helps to mitigate the shortcomings of the ignition time to reduce the liquid rocket engine compared to the shortcomings of the solid rocket engine.

The disadvantage is that using liquid missiles with "heat" emission, more suspension and shock absorbers are required than solid missile + water surface.

The second method is ignited in the water, and the transmission barrel is not high, and it is powered by water, the overall is more controllable, and the wind wave is less affected, but the missile itself is high because of the underwater launch environment bad. The launch method used by the M51 submerged missile of the future generations has always had problems.

The last type is to use high pressure gas to shoot the missile out of the water and ignite in half air. This way, the US subjury missile is this way, its maximum difficulty is that the timing of ignition must be very accurate, and dozens of tons of missiles are basically strong after breaking the water. To drive the rocket engine before it, otherwise the missile will fall Enter the sea.

Nowadays, Germany's R & D directions are directly launched in the launch tube, but the research progress is not smooth. This is already a fifth missile exploded in the launch tube.

"Is it going to change a launch mode?" Looking at the huge water column scattered, most of them returned to the "pool", some people said. In addition to igniting direct in the launch tube, Jenik also told them in the principle of the water.

Another researcher shook his head. "But our missile cold emission technology has not yet been perfect." Cold launch is an emission of the main engine when the auxiliary power is emitted from the launcher, and then ignited the launch mode of the main engine when the missile reaches a certain height. The missile and its launching equipment are not affected by the high temperature gas generated by the leading engine engine, so it is called cold emission.

Cold launch is not new, and it is used in the submarine very early. During the World War II, the mines in the lattice of the submarines in the World War II were the injection of high pressure gases into the launch tube in the lane, so that the internal and external air pressure is equal. When launching, the front sealing cover opened, the high pressure air was poured from the tail of the launch tube, and the torpedo was pushed out.

However, a two-ton torpedo shot and put a few tons or even a dozen tons of missiles vertically, not a difficulty level.

The middle-aged man who is headed by a few people can't argue. "This has failed a few times, you have to give up? Can you have a mistake under the Hall? If you have any negligence, you will have a failure, clean the water, clean the launch pad." One mentioned the Jenik Temple, everyone suddenly didn't have a voice Leave the observation, busy again.
