Lockheed Martin is a world-renowned military giant. The F-35 joint attack aircraft developed in series is their latest fist product. The official announcement of this aircraft reveals two major operational targets, and the second is the Russian-made S-400 surface-to-air missile system.
Although it took Russia 21 years to build the Su -57 fighter with intergenerational properties, and it also came to Moscow Air Show for static display in order to expand sales, in the eyes of Lockheed Martin, its operational value is not as good as that of S-400 surface-to-air missile system.
No matter how strong the air defense capability of the S-400 is, it is always a passive means. Lockheed Martin's number one opponent for the F-35 is AVIC· Cheng Fei's fifth-generation fighter J -20.
The biggest difference between modern warfare and the past is that in the past, the research and development of weapons and equipment followed the demand, and whatever weapons were needed in the war was built. Now it is a design war in the opposite direction. For example, the Red Flag Military Exercise in the United States and the Red Sword Exercise in China all shoulder the mission of designing wars. It used to be passive reaction, but now it is active control.
The outstanding feature of the J-20 is its ability to control war. As a milestone and watershed in the development of China fighter, the development of this aircraft is different from any previous fighter. The design team led by Yang Wei, the chief engineer, completely changed the traditional rules of passive response requirements, and put forward the engineering concept of "battle scene-performance requirements-design and manufacture" in another way.
Innovation is never imagined, but a qualitative change based on the accumulation of strength. The success of the J-20 is mainly due to the substantial improvement of comprehensive national strength, such as the upgrading of financial resources, manpower and supporting industrial chains, which are completely different from the past.
The J-20 is also a strategic pioneer in the integration of national defense and civilian technology. For example, the integrally formed titanium alloy frame, carbon fiber and metamaterial used in this machine are all developed and produced by private enterprises, which really gathers the strength of the whole society to build the country.
According to the open view data of the J-20, the U.S. official analyzed the radar cross-sectional area of the front of the plane through three-dimensional modeling. The calculated data is 0.027 square meters, which is better than 0.038 square meters of F-35, and is between F-22 and F-35. This data is also in line with the design and positioning of the J-20' s outstanding stealth performance advantages.
The real data may be better than the data calculated by the United States, because they are based on their own application level of stealth materials, without considering that the J-20 uses a metamaterial stealth film that is ahead of the whole generation. This material not only has many stealth frequency bands, but also has maintenance advantages.
With a history of 5,000 years, we have experienced too much, so we have accumulated development experience far exceeding that of other countries. For example, the J-20 borrowed the story of horse racing in Tian Ji. Under the background that there is still a big gap between the overall strength and the opponent, we should fully optimize the allocation of resources, seek advantages and avoid disadvantages, and achieve strengths and avoid weaknesses.
In the words of Chief Engineer Yang Wei, "We have created the lifting body ribbon duck layout of the J-20 in the world", which is called "a small aspect ratio high-lift body layout" in the paper of Chief Engineer Song of J-10. Small aspect ratio is to meet the needs of supersonic cruise flight, and high-lift body is to meet the needs of high maneuverability, which can combine two contradictory design requirements. This is a great innovation of the J-20.
Informatization is another major performance advantage of the J-20, and its situational awareness equipment is at the same level as the F-35 joint attack aircraft and superior to the F-22.
As far as airborne radar is concerned, the United States highlights its high-power multi-target tracking capability, and Russia's Su -57 has the advantages of three-sided array radar. We have both advantages. For example, the KLJ-07A equipped with the Xiaolong block3 fighter has a three-sided array version, and its performance index is at the same level as the An /APG-8 1 radar used by the F-35 fighter.
We also launched the world's first airborne air-cooled active phased array radar, and the third generation of aircraft was modified in situ. The public model can already achieve such accomplishments, not to mention the public J-20 airborne radar. It can be said that this former radar crown has been completely "cabbageized" by us.
When introducing the performance of the J-20, chief engineer Yang Wei also mentioned that it has many unique skills, which we don't know, but it must be based on the advantages of the carrier-based platform. For example, the built-in bomb bay is superior to F-22 and F-35, and the side bomb bay innovatively invented the missile external ignition scheme, which has the best advantages in both quick response and stealth, and overcomes the shortcoming of increasing the radar reflection area for a long time after the F-22 and F-35 bomb bays are opened.
In AVIC's latest J-20 promotional video, we can appreciate the details of the opening of the main bomb bay. The length, width, size and depth of the bomb bay are much larger than those of F-22 and F-35. What benefits will this bring?
Some people say that the J-20 can play the advantage of stealth kicking in wartime, but the chief engineer Yang Wei doesn't think so, because the value of J-20 is not limited to kicking the door, it can do air combat, ground attack, sea attack, long-range interception and hunting of enemy air strategic nodes (early warning aircraft, tankers, electronic fighters, etc.). ).
The main bomb bay has the advantage of large volume design, so it can carry airborne ammunition with longer range and larger tonnage, which is the premise of carrying out air special operations tasks, and this is the concrete embodiment of designing and controlling wars.
What is the ultimate significance of the J-20? In the words of Yang Wei, the head teacher, when the country needs it, it will definitely stand up. Thus, more than half a century ago, the earth-shattering slogan of the older generation of military workers in the depths of the northwest desert was "build an atomic bomb and stand up straight!" .
Since the 1990s, there has been a new sword hanging over our heads, which is the stealth technology monopoly represented by B-2 bombers and F-22 fighters.
Now, although we have an invincible trump card in the new century, we will never stop developing new equipment. J-20 is just a small goal for us. For the next generation fighter, Yang Wei said this: We will pursue aviation to serve the country, and the pace of building an aviation power will not stop. We must accelerate the leap-forward development, that is, beyond the J-20 platform, pursue higher goals and meet the strategic needs of the country. There is no doubt about it.
