(Recently, the domestic network exposed photos of the J-20 suspected test dual-mounted missile pylon)
Recently, the domestic network exposed a domestic heavy five-generation stealth fighter J-20 mounted on the suspected dual-unit. The photos of the missile pylon test. As the world's most advanced fighter, in order to achieve higher stealth performance, the fifth-generation stealth fighter generally no longer uses the external mounting method. The design of the fifth-generation stealth fighter's built-in magazine comes from this. However, not only China, but all countries that have successfully developed five generations of stealth fighters, including the United States and Russia, are also experimenting with the plug-in capabilities of stealth fighters, and this method of use will obviously destroy the stealth effect of stealth fighters.
However, from a practical perspective, such a use test is also necessary. The stealth fighters of China, the United States and Russia are all designed with plug-in capabilities and tested in actual use. Obviously, it will not be unreasonable. of. In some specific cases, even the fifth-generation stealth fighters known for their stealth can actually be used in non-stealth combat applications.
(The double-mounted missile pylon is relative to a single missile pylon. The biggest feature of the double-mounted missile pylon is that it can mount more missiles. The latest American F15X is even designed There are triple-mounted missile pylons)
The Chinese, Russian and American stealth fighters are all designed with external weapon capabilities.
Although an important standard of the five generations of stealth fighters is to no longer use external weapons and carry out weapons built-in design, but the world The stealth fighters developed by countries that have independently developed five generations of stealth fighters are all designed with external capabilities. The United States, which was the first to successfully develop and apply the fifth-generation stealth fighter, has two fifth-generation stealth fighters, the F22 and F35 series, both designed with external weapon capabilities. The U.S. F22 fifth-generation stealth air superiority fighter often appears as an external vehicle carrying a secondary fuel tank. This is especially true for the latest US military's F35 series of stealth fighters. The United States has designed and developed many external weapon configurations for the F35 series of stealth fighters, and the corresponding external weapon tests have already been completed. As for the Russian Su 57, there is no need to say that the vast majority of the aircraft is in external weapon mode. According to this, some people even doubt the performance of the Su 57's built-in magazine.
(Different from the quadruple and six-mounted missile pylons designed and used on armed helicopters, the design and use of multi-unit pylons for fighter jets is more complicated. China’s dual-mounted missile pylon technology has Mature and began to roll out the application)
is similar to the fifth-generation stealth fighters of the United States and Russia, and the Chinese J-20 fifth-generation stealth fighter also has external weapon capabilities. As early as one or two years ago, the domestic network exposed photos of the J-20 mounted with four auxiliary fuel tanks. In the last year or two, the domestic network once again exposed the photos of the J-20 mounted with two auxiliary fuel tanks. The photos can prove that, similar to the fifth-generation stealth fighters of the United States and Russia, China has also designed external weapon capabilities for the fifth-generation stealth fighters. The newly exposed photos of the J-20 suspected of carrying out a dual-mounted missile pylon test can further prove this point, and it can also prove that the J-20's external weapon use mode is real, and the similar capabilities of the American stealth fighter are equivalent.
(Not only the missile pylon, the F-20 has also been tested with two auxiliary fuel tanks and four auxiliary fuel tanks. The external mode used in these tests will obviously destroy the stealth effect of the stealth fighter)
is different from the quadruple pylons and six pylons used by armed helicopters, the design and use of multi-mounted pylons for fighter weapons is very complicated. This design can well increase the number of weapons mounted on the fighter, but the technical difficulty is not small. It is only in recent years that China has been confirmed to use multi-mounted fighter pylons on a large scale, and the domestically produced J-10C fighter jets have been confirmed to use dual-mounted weapon pylons. In fact, the duplex pylon used by the F-20 exposed this time is likely to be technically related to the duplex pylon used by the F-10C.
And all these can fully explain that with the improvement of China's fighter composite pylon manufacturing technology, the use of composite multi-mounted pylons for Chinese fighters has become more and more common. As the most advanced five-generation stealth fighter in active service in China, the J 20 If you don’t consider stealth, the latest multi-unit mounting system of our army has been applied.The overall performance has also improved a lot.
(not only in China, the world’s first stealth fighter F22 also often shows up with the auxiliary fuel tank mounted, this mode of use will also destroy the stealth performance of the fighter itself)
is nothing but , Whether it is the external weapon design of the F22 and F35 series, or the external weapon use test of the Chinese F-20, the F22/35 and F-20 in this state obviously sacrifice some stealth performance. As for why the Chinese and American aviation departments carry out such a design, it is probably also related to actual combat.
, like the cannon, is a design inspired by actual combat.
As mentioned earlier, the biggest feature of stealth fighters is the stealth design. In order to achieve higher stealth performance, the stealth of China, the United States, Russia and other countries In the fighter project, the usual use mode of traditional fighter external weapons has been adjusted to the built-in magazine design. The five generations of stealth fighter projects in China, the United States and Russia, without exception, have focused on the issue of built-in magazines, and have carried out very detailed designs. However, in real applications, even stealth fighters have the need for external use.
(the second stealth fighter F35 series of the US military is no exception)
To give a simple example, the stealth fighter transitions from a non-combat state. According to general transition requirements, during the transition process, the voyage design of the fighter aircraft will play a role at this time. In order to avoid frequent landing and refueling, many fighter jets will also use auxiliary fuel tanks during the transition process. In this state, for stealth fighters, this way of using auxiliary fuel tanks to increase range and reduce stealth performance is obviously necessary, because this state almost completely does not need to consider air combat issues.
Therefore, even for stealth fighters with stealth as an important "weapon", it is actually necessary to design the ability to use external weapons that destroy the stealth performance. This design and use only needs to be set in a necessary state. The performance of the stealth fighter has no effect.
(not to mention the Russian Su 57, most of the aircraft currently uses the plug-in mode)
Moreover, as the scale of stealth fighters gradually expands, the future sky It is very likely that stealth fighters will soon be dominated by stealth fighters. That is to say, after stealth fighters completely replace traditional fighters, almost all military tasks that traditional fighters are responsible for today will also be given to stealth fighters, such as cruise missions. In the air cruise alert state, when the threat level is significantly lower, the complete stealth mode is obviously redundant. In this state, the stealth fighter will reduce some stealth performance, mount the auxiliary fuel tank or even external weapons, if necessary It is also feasible.
For example, during deterrent air cruises to some small countries around the United States, if the US military uses stealth fighters, it is obviously not necessary to turn on the full stealth mode, because some small countries have even lost the use of jet fighters. Ability, for such a level of national "threat", the deterrence of stealth fighters using non-stealth mode is more than enough, and there is no need to waste the stealth mode of stealth fighters.
(The biggest advantage of a stealth fighter is its stealth performance, but in actual combat, it is very likely to encounter scenes that do not require stealth. At this time, the value of the plug-in will be highlighted)
Therefore, just as modern fighters are still almost entirely designed with outdated cannons, it is actually necessary for stealth fighters to design external weapons. In actual combat applications, external weapons can also play a role, especially This design is even more indispensable when the scale of stealth fighters is getting larger and larger. Because the military power gap between countries in the world is sometimes very large, there are still some countries in the world that have almost no jet fighters installed in the air force. When the day when all the major air force fighters are invisible, there will be no jets at all. In the process of fighting against the national air force of fighters, the stealth fighters in the fully stealth mode are obviously a killer. There is no need to use the full stealth mode at all. How to make it more economical will probably be the most important consideration at that time.(CMN)
