In fact, not only Jean Renault, but also the media reporters and the audience who rushed over after seeing the details of the FC-21 fighter have such a simple method that we did not expect frustration.
There is no other reason for this. It is only because part of the design of the FC-21 fighter jet, especially the weapon pylons, did not use the so-called belly bomb bay treatment that they had previously imagined, but used a half-and-half design. The buried weapon pylon embeds two mid-range air-to-air bombs and two close-range combat bombs into the belly of the aircraft.
In this way, the FC-21 fighter does not increase the radar reflection cross section much from the front angle, and the drag of the aircraft is even negligible.
Speaking of this kind of semi-buried pylons is not new, old bombers and attack aircraft have been used, but no one associates this type of semi-buried pylons with overall stealth.
I feel that if you want to be invisible, you must use a belly bomb bay.
As everyone knows, the belly bomb bay not only has to consider the overall design issues, but it is also extremely difficult to manufacture and the cost is ridiculously high. That is to say, a large country like the United States can afford it, and ordinary regional powers and regional hegemons simply cannot play .
In contrast, although the semi-buried pylon of the FC-21 fighter is not as tall as the belly bomb bay of the fourth-generation aircraft, it has initially realized the ability of radar stealth in a cheap and reliable way.
Perhaps in the confrontation between big powers, this stealth effect does not necessarily play a big role, but for countries such as regional powers and regional hegemons, the FC-21 fighter is enough, not to mention the price of the FC-21 fighter. Up to the height of the fourth-generation machine, these countries can fully afford it.
Of course, the most depressing of these people is still Jean Renault. In fact, it is not only the semi-buried weapon racks that made this Dassault Group executive who participated in the design of the Mirage 2000 fighter jets beat his chest. It is the overall design concept displayed by the FC-21 fighter.
To say how good the craftsmanship of the FC-21 fighter is and how exquisite the level is, it is not necessarily true. Let alone the quality of the Rafale, the craftsmanship level of any Western fighter is better than the current FC-21. Fighters are better.
That's all, the key is that in terms of details, the FC-21 fighter jet does not achieve complete stealth. For example, the air inlet uses a shock parallel air inlet similar to the F-22, but except for the similar appearance. There is not the slightest resemblance inside.
After all, the F-22 uses a bent Carter air inlet to achieve radar stealth of the engine blades; the FC-21 fighter does not do any processing in this aspect at all, and it still uses the straight-through type used by the third-generation aircraft. The air inlet, so that Renault can clearly see the metallic reflection of the engine turbofan blades through the air inlet.
Even the air intake is so simple, not to mention the aero-engines used, that is, two ordinary medium-thrust turbofan engines, and there is no so-called vector nozzle, so it is impossible to have the so-called super maneuvering.
Similarly, there is no shortage of weapons under the wings, because the mounting point connectors below are very obvious. There are a total of six mounting points on the wings on both sides. In other words, the FC-21 fighter can enter the third-generation aircraft in the same way. Various weapons and equipment are normally mounted under the wings, making it a multi-purpose fighter with ground attack capabilities.
The details of the craftsmanship are not superb, and some of the design treatments are too simple and straightforward. It is such a combat aircraft that can not be put on the table by taking out various parts separately, and it is still a surprise for Jean Renault.
Because the FC-21 fighter jet put all the emphasis on the creation of stealth aerodynamic shape.
It is no exaggeration to say that the FC-21 fighter jet only did one thing right, that is, the overall stealth aerodynamic layout. Even if some details are still lacking, or even slightly naive, the determination of this stealth aerodynamic layout is just like Like Dinghai Shenzhen, those imperfect details have become dull, even insignificant.
After all, the positioning of the FC-21 fighter is a third and a half generation rather than a real fourth-generation fighter. It is very successful to be able to carry two medium-range bombs and two combat bombs with a frontal radar reflection cross-section of only 0.45 square meters. If the size is less than 0.1 square, you can buy F-22 from the United States and let the Americans take care of you!
What's more, as a stepping stone to the battlefield, the low detectability of the FC-21 fighter is sufficient for regional powers to cope with the real threats surrounding it. Because of this, the design of the FC-21 fighter can be said to be very successful.
That is, the main performance is outstanding, the actual needs are taken into account, and more importantly, the cost is reduced. It can be said that it is a super cost-effective product.
Of course, if all this is done, Jean Renault’s arrogant personality will not be so indifferent. There is no way. As a senior aviation industry executive, he is very clear that a combat aircraft is not everything going to be good after it is formed, but needs. Continuous improvement and upgrading can finally reach the real design state.
Obviously, the FC-21 fighter is not completely designed. The next improvement must be the focus of the development of the FC-21 fighter, and this is what makes Renault fear.
No matter how to change the Rafale fighter, it will be three and a half generations to break through the sky; if the FC-21 fighter follows the core of the stealth aerodynamic layout, what is it?
Isn't that the real fourth-generation machine!
No...impossible...absolutely impossible. How could a big country in the East have four generations of aircraft? Even their highly developed France does not have four generations. A backward and ignorant major country in the East can never have four generations of aircraft. may!
However, while Jean Renault was watching the FC-21 fighters in Abu Dhabi fighting between heaven and humans, an FC-21 fighter jet suddenly cut through the sky over a certain area in the central part of the country. It was located 60 kilometers above the air force. In the command post of a certain missile unit, the head of the headquarters company and the army leaders stared at the seemingly absent bright spot on the radar screen, frowning, and then tilted their heads to ask the leader of the ground-to-air missile unit next to him: "Grab Reached?"
The leader of the surface-to-air missile unit squinted and carefully checked the data on the radar~www.wuxiaspot.com~ and compared the situation on other detection equipment, and shook his head with an ugly expression: "Not completely caught."
"If you catch it, you will catch it. If you didn't catch it, you didn't catch it..." The head of the headquarters immediately sank after hearing this: "What does it mean to not catch it completely?"
"That's...that's...that is, the lock signal of the fire control radar is unstable, and the missile is shot out!" The leader of the ground-to-air missile force quickly explained.
"I can't even shoot out the missiles. Doesn't it mean that this air defense missile system is useless in front of the stealth aircraft? No need to talk nonsense. This system will be fired back and redone. If it doesn't change well, just dismount it!" Is straightforward.
The leader of the surface-to-air missile force was shocked when he heard the words, and quickly explained: "Chief, this air defense missile system is..."
"Okay, no need to explain!" As a result, before the leader of the ground-to-air missile unit finished speaking, he was directly interrupted by the head of the headquarters: "True Dragon II is just a low-end stealth aircraft, and your system can't catch it. What do you do if a real stealth aircraft like F-22 comes? Are you waiting to be a lamb to be slaughtered?"
