J -20 three questions: size greater than the F-22 price may be expensive

After years of looking, a skyrocketing number of F-20 military fan emotions so excited, enthusiastic and lively discussion. For the entire machine, including four generations of fighter aircraft made a number of new questions, Listen to the Xinhua News Agency, "World Military" magazine editor in chief, a military expert Chen Hu interpret it for us.

Doubt one: four generations of machines, or the Five machine?

F-20 in the end is the fourth generation machine, or the Five machine, which is an old topic, F-22 came from the United States, began to appear on the so-called "fourth generation" and "Five" of the two is called.

The United States is based on the operational effectiveness of combat aircraft has a large span of progress to the sub-generation: As F-86, this is the era of the first generation of jet fighters; after the F-4 "Phantom" is a typical second-generation fighter aircraft; to the F-15, F-16, F-13, F-18, the third generation of American jet fighters; to the F-22, F-35, which is a fourth generation fighter aircraft.

Russia and the United States points system is different, it is typical of the major technological advances in ways to plan generation: Americans actually like the previous two generations, such as the MiG -15 is a typical first generation; to the MiG - 21 is the second generation; But by the time the third generation of Russians to use a variable-wing aircraft as a generation technology, such as the MiG -23, while the variable-wing Americans think that the combat effectiveness of technology on the aircraft does not have much impact , so there is no generation of it as an independent; to the Soviet Union and -27 is the fourth generation; to more below, the current T-50 is already the fifth generation. This is the first four generations of the Five Dynasties and the cause.

From aircraft engineering and operational effectiveness of speaking, I think, by way of four generations of machines and it is still actually a scientific nature. For example, called the J-20, military enthusiasts or weapons enthusiasts, more recognition is divided into four generations of machines, I also agree with this classification method. The network, F-20 has a nickname, called "ribbon" is actually a "fourth generation" of harmonics.

Second question: the meaning of the fourth generation machine how much?

Overall, as a symbol of the modern fighter, "won" a four-generation machine means that have been able to master the world's top air combat platform technology. Specifically, four generations of machines for different countries, it embodies the meaning are different.

For example, the United States that the F-22 can make the Air Force has any other country or any region of the asymmetric advantages the Air Force absolutely. At the same time, it believed that the advent of F-22 can make this advantage has been extended to 2020 or even longer. This is for the United States, military significance, political significance, economic significance is very important.
Countries outside the United States, its meaning may also be different.

First, it broke the U.S. monopoly in the state of the technology. In fact, my personal view,is a fourth generation machine only advanced conventional air combat platform, that is, it is only a plane, meaning it is not necessary infinite overstating.

In fact, modern air combat is the combat, four generations of machines such asadvanced aircraft, but in this system occupies an important position among the just. Onesuperb combat performance of weapons, does not directly equal to the combat effectiveness of the promotion.

Question three: a good large or small better?

F-20 first appeared online in the photos, some of the so-called foreign experts to do acomparison, they find reference to estimates based on photos and found the size ofF-20 than the F-22 and T-50 should be large, so large means that Something? Goodlarge or small better?

The larger the size of the aircraft do, the greater the weight, then the payload, the greater the fuel load, the more space inside the body, you can install more advanced, largeairborne electronic equipment. From this perspective, the large aircraft from theoperational capability is an advantage, especially in the fourth generation machine.Because the characteristics of four generations of machines is the biggest stealth, andcombat capability of stealth given that the first operational mission is to attack rather than air combat.

In this sense, the four generations of ground attack machine performance can be said to be more attention, payload, fuel load, large, range far is a critical indicator of a largeaircraft is clearly a big advantage.

In addition, for the fourth generation stealth fighter, there are still a factor to consider is the way of stealth aircraft weapons mounted. If the aircraft is larger, then the machinecan be done within the bomb bay to larger, can carry larger and heavier, longer rangeairborne weapons, which some of the remote attack high-value, high-threat target, such as playing Aircraft carrier, there is a very great significance.

At the same time, the aircraft also has big big problems and shortcomings. From a costpoint of view, large I am afraid you will. Similarly, from the development and production of technical difficulty, it may be necessary to high. Can say that each have their own littlebig advantage. (Guangzhou)
