In order to demonstrate their own strength, countries are vying to make themselves".Fifth-generation aircraft"The results of research have been published to the world, and they were once called".The most advanced in the worldThe number of fifth-generation aircraft is increasing to 22 day by day.
Recently, it has been frequently revealed that the fifth-generation aircraft of many countries are not worthy of the name, and they are even jokingly called "4.".5th generation aircraft"!
First of all, let's understand what is a fifth-generation aircraft, in fact, the international definition of fifth-generation aircraft has long been defined. First of all, it is necessary to have extremely strong stealth abilityAnd the ability to cruise at supersonic speed will also be longer than that of third- and fourth-generation fighters, and it will be possible to quickly pursue enemy aircraft.
The design of the engine nozzle of the fifth-generation aircraft is more reasonable, it can achieve flexible rotation, and can accurately hit the enemy aircraft when fighting the enemy. Compared with the previous fourth-generation aircraft, the radar tracking system of the fifth-generation aircraft has been greatly improved on the original basis.
The fifth-generation aircraft can not only lock on to hundreds of targets at the same time, but can even be initially divided again according to the threat level of the target.
It can be said that the emergence of the fifth-generation aircraft is of revolutionary significance, and only a fighter with the above performance can be called a real fifth-generation aircraft. According to the comprehensive performance, we benchmark the fifth-generation aircraft of various countries one by one.
Of course, the first sequence of "China, Russia, and the United States" naturally has its own place in the era of fifth-generation aircraft, and the fifth-generation aircraft developed by various countries have their own merits. But Japan was not so lucky.
Japan's fifth-generation aircraft "Shinshin" was finally announced to be out of service after 32 test flights. The air intake of the "Heart" is designed in an S-shape, and the design of the outer edge of the fuselage is also remarkable. Unfortunately, the tonnage of the "Heart" is only equivalent to the weight of a truck, so the space is very small.
Without magazines and radars, the "mind" is only a vain appearance, and such a fighter is naturally unqualified。The X-3 announced later only existed on the drawings, so far the Japanese fifth-generation aircraft is really disappointing.
In the competition of fifth-generation aircraft, although South Korea failed to enter the first sequence, its ambitions have not diminished, so it began to focus on the research of fifth-generation aircraft as early as possibleAt one time, he made a bold statement that "South Korea will build the world's most advanced fifth-generation aircraft"!
Although the Korean slogan was shouted loudly and began with great fanfare, it is a pity that "the thunder is loud and the rain is small". Clueless, South Korea turned its attention to its "big brother", the United States. The U.S. alone has 21 patents for fifth-generation aircraft
Of course, the United States does not give its own ambitious little brotherAt the beginning, the United States only provided South Korea with a "low-end configuration", and South Korea was naturally a hundred unhappy.
In order to fulfill its ambitions, South Korea decided to use its "money capabilities", and the United States finally agreed to sell some of its technology to South Korea.
Under South Korea's "patchwork", the KF-21 was finally completed, but unfortunately South Korea had not had time to scream, and it was embarrassing to find that the KF-21's fuselage was actually anti-** wingThis leads to the reflection of radar waves, in other words, the KF-21 is not able to do even the most basic stealth.
Of course, the second sequence of the fifth-generation aircraft is not without outstanding, such as the fifth-generation aircraft NGF jointly manufactured by Germany and France, whose stealth performance even surpasses the level of the existing fifth-generation aircraft. Indonesia, which "does big things in a muffled voice", also made the I-20 by imitating China's J-22!
Through the fifth-generation aircraft, it is not difficult to see that some countries are strong in the middleSome countries are militarily strong, as the old hegemon of the United States, it developed the F22 as early as 24 years ago is still the most advanced existence of the fifth generation aircraft.
Its radar reflection area is even 0005 square meters,Its stealth performance is still "resistant" even today.
In addition to the F22 in the United States, the F35 is also in the ranks of the fifth-generation aircraft, and the F35 is also divided into three models, which can realize one machine for three purposes, so versatility has also become one of its advantages. And the F35 uses stealth absorbing materials to convert the stealth performance to the extreme.
The F35B is equipped with an HP F135600 turbofan engine, and its physiological system is Rolls-Royce, so it is consistent with the "predecessor" F22 in terms of cost. Of course, if the sky-high price of the F35B is higher than the high integrated system, then the F22 has another reason.
The main reason for the high value of the F22 is its maintenance cost, because the F22 was born relatively early, so its production line has long been dismantled. The number of parts that can be used is decreasing, and the cost of maintaining them is naturally rising.
And there are only a handful of countries that can compete with the United States. Until China, as a latecomer, used the J-20 to break the situation of "Russia and the United States" dominating the two countries in one fell swoop. The J-20 pays more attention to its innovation and improvement than imitation.
The young J-20 is a cut above the F22 in avionics, and the J-20's fuselage is designed to be slender and capable of accommodating more missiles。Of course, although China has been making great strides on the road of military development, it is still slightly inferior to "Russia and the United States" in the design of engines.
However, the comprehensive combat level of the J-20 is still the best, and experts say that the J-20 will extend its improved version, which is currently underway. Compared with the F22, which is about to expire in service, it is obvious that the J-20 has infinite possibilities.
Compared with the United States' extravagant spending regardless of the cost, China has a scientific and strict control over costsWhile not hindering the technology, the J-20 successfully controlled the cost at 70 million, which also laid a good foundation for subsequent research and development.
The emergence of the J-20 is an indispensable mark in the era of the Five Dynasties, and it also symbolizes that China has achieved a leap forward in scientific research achievements, and China will move towards a new world on the road of continuous breakthroughs!
