It is estimated what is the liquid fuel ampuration of North Korean missiles

　North Korea's self -proclaimed missile, which was launched on January 5, has been explained in the official statement of the next day that the reliability of the fuel ampul system has been verified.This is the second confirmation this time, as it appeared in the next day's explanation in "Mars 8" launched on September 28, last year.

　암풀 (ampoul) is "ampoule", which means "sealed", which means that you can wait for a long time while filling with a strong corrosive missile fuel. It seems.

　Missiles must be lighter in their own components, including fuel tanks, to earn flight distance and payload.However, if the parts that touch the highly corrosive liquid fuel are too light and thin, they will be eroded and will not be able to withstand a long time, and dangerous liquid fuel will leak out.Increasing fuel filling while reducing the weight of missile components, the technology to achieve conflicting demands at the same time is required.

Reference: Russian military term "ampoulized rocket"

　For example, the item published in the military statement on the Russian Ministry of Defense's official website will be a good reference.

　North Korea has introduced many missile technical terms from Russia, so it is highly likely that this word refers to the same meaning.In this Russian military term dictionary, an ampurized rocket is fully closed, fuel and maintaining the necessary pressure in the tank, so that the fuel is left.The system that keeps waiting for a long time is explained.

　In particular, the huge ICBM, a huge heavy ICBM, which is deployed in the Russian army, enables a very long -term liquid fuel -filled opportunity for 10 -year units of 10 -year.

　It is not yet known how much technical level of liquid fuel that North Korea calls it.It is said that even the old scud short -range ballistic missile can be waited for about one week to two months according to the condition of the fuel filled, so it should have been held for this time.

　However, North Korea mentions in the official statement on September 29, 2021, mentioning Mars 8 as "the first ammon -made missile fuel system".As long as I'm saying it's my first time, I don't think I'm talking about the technology that has been implemented on old scuds.Perhaps it is possible to be able to wait for a year for a longer period with fuel filling from six months.

Apoulation is a sealing and not a cassette replacement type.

　In some reports from some Japan and South Korea, the incorrect explanation was that the ampuration was "a method of filling the liquid fuel in a container in advance and fitting the container into a missile every time it is fired."This is physically impossible.The filled fuel tank built into the missile is large and heavy, the shell is thin, weak and low, so it is not a structure that can be easily removed.In the first place, the filled fuel tank occupies the weight of the missile and most of the overall length.If you replace such a large, heavy and weak structure carefully so that it does not break, it will be faster and easier to replace the whole missile.

　The following is a wrong commentary report.

　Please note that many Korean media have reprinted this, as the Korean major telecommunications company, "Yonhap News," has reprinted it, and some Japanese media have been posted as it is.
