Chapter 1289 Focus: Stealth Aerodynamic Shape

    In fact, not only Jean Reno, but also the media reporters and the audience who came later felt frustrated when they saw the details of the fc-21 fighter jet. Why did we not expect such a simple method?

    The reason for this is for no other reason than that part of the design of the fc-21 fighter jet, especially the weapon rack, does not use the so-called belly bomb bay as they had imagined before, but uses a semi-automatic bomb bay.  The buried weapon rack embeds two medium-range air-to-air bombs and two close-range combat bombs into the belly of the aircraft.

    As a result, the fc-21 fighter jet does not increase the radar reflection cross section much from the front angle, and the resistance of the aircraft is negligible.

    Speaking of which, this kind of semi-buried pylon is not new. It has been used on old bombers and attack aircraft, but no one has associated this semi-buried pylon with overall stealth.

    They all think that if you want to be stealthy, you must use the belly bomb bay.

    As everyone knows, the belly bomb bay not only has to consider the overall design issues, but is also extremely difficult to manufacture and the cost is ridiculously high. Only a big country like the United States can afford it, and ordinary regional powers and regional hegemons simply cannot afford it.  .

    In contrast, although the semi-buried pylon of the fc-21 fighter jet is not as tall as the belly bomb bay of the fourth-generation aircraft, it has initially achieved radar stealth capabilities in a cheap and reliable way.

    Perhaps in the confrontation between major powers, this stealth effect may not play a big role, but for countries such as regional powers and regional hegemons, the fc-21 fighter jet is enough, not to mention the price of the fc-21 fighter jet is impossible  Reaching the level of fourth-generation aircraft is completely affordable for these countries.

    Of course, the most depressing among these people is Jean Reno. In fact, what makes this executive of the Dassault Group, who participated in the design of the Mirage 2000 fighter jet, beat his chest is not just the semi-buried weapon rack, but  It is the overall design concept displayed by the fc-21 fighter jet.

    It¡¯s hard to say how good the craftsmanship of the fc-21 fighter jet is and how exquisite it is. Let alone comparing it to a high-quality product like the Rafale, the craftsmanship level of any Western fighter jet is better than the fc-21 in front of you.  Fighters are better.

    That's it. The key is in the details. The fc-21 fighter jet does not achieve complete stealth. For example, the air inlet uses a shock wave parallel inlet similar to the f-22. However, except for the similar appearance  Internally, there is no similarity at all.

    After all, the F-22 uses a curved Carter air inlet to achieve radar invisibility to the engine blades; the F-21 fighter does not do anything in this regard at all, and still uses the straight-through type commonly used by third-generation aircraft.  The air inlet was so large that Jean Reno could clearly see the metallic reflection of the engine's turbofan blades through the air inlet.

    Even the inlet is so simple, not to mention the aero engines used. They are just two ordinary medium-thrust turbofan engines. There is no so-called vector nozzle, so there is no so-called super maneuverability.

    Similarly, there are no shortage of weapons mounts under the wings, because the mount point connectors below are very obvious. There are a total of six mount points on the wings on both sides. In other words, the fc-21 fighter jet can be used as a third-generation aircraft.  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 exquisite, and some design treatments are too simple and direct. It is such a combat aircraft that cannot be put on the table if the various parts are taken out individually, but the integration still makes Jean Reno amazed.

    Because the fc-21 fighter jet puts all its focus on the creation of a stealth aerodynamic shape.

    It is no exaggeration to say that the fc-21 fighter jet only does one thing right, and that is the overall stealth aerodynamic layout. Even if it is still lacking in some details and even a little naive, the determination of this stealth aerodynamic layout is as good as  Like the Dinghai Shenzhen, it makes those imperfect details dim, even insignificant.

    After all, the fc-21 fighter jet is positioned as a third-and-a-half-generation aircraft rather than a true fourth-generation aircraft. 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 you want  If it is less than 0.1 square meters, yes, buy F-22 from the United States, and see if the Americans will pay attention to you!

    What¡¯s more, as a stepping stone on the battlefield, the low detectability of the fc-21 fighter is enough for regional powers to deal with the surrounding real threats. Because of this, the design of the fc-21 fighter can be said to be very successful.

    It not only has outstanding main performance, but also takes into account the actual needs. More importantly, it reduces the cost. It can be said to be a highly cost-effective product.

    Of course, if this is all, Jean Reno's arrogant personality will not be so uneasy. There is no way. As a senior aviation manufacturing executive, he knows very well that a combat aircraft does not mean that everything will be fine once it is formed, but needs  Continuous improvementOnly at this level can the real design state be finally reached.

    It is obvious that the fc-21 fighter jet is not in a complete design state. The next improvement must be the focus of the development of the fc-21 fighter jet, and this is what makes Renault afraid.

    No matter how the Rafale fighter is modified, it will only be three and a half generations. If the fc-21 fighter follows the core of stealth and aerodynamic layout, what will it be?

    Isn¡¯t that a real fourth-generation machine?

    Impossibleimpossibleabsolutely impossible. How could a certain big country in the East have fourth-generation aircraft? Even their highly developed France does not have fourth-generation aircraft. There is no way that a backward and ignorant big country in the East has fourth-generation aircraft. It's absolutely impossible.  possible!

    However, just as Jean Reno was watching the battle between heaven and man between fc-21 fighter jets in Abu Dhabi, an fc-21 fighter jet suddenly pierced the sky over a certain area in the central part of the country. It was sixty kilometers away from the air force ground and air here.  In a certain command post of the missile unit, the head of the headquarters and a group of military leaders stared closely at the seemingly invisible bright spot on the radar screen. They couldn't help but frown, and then turned their heads and asked the leader of the surface-to-air missile unit beside him: "Grab it."  Reached?"

    The leader of the surface-to-air missile unit squinted and carefully looked at the data on the radar, then compared the situation on other detection equipment, and shook his head with an ugly expression: "Not completely caught."

    "If you catch it, you catch it. If you don't catch it, you don't catch it" When the head of the headquarters heard this, his face immediately darkened: "What do you mean not fully caught?"

    "It's justit's justit's just that the fire control radar locking signal is unstable and the missile is shot out!" The leader of the surface-to-air missile force quickly explained.

    "If it can't even fire out missiles, doesn't it mean that this air defense missile system is useless in front of stealth aircraft? No need to talk nonsense, this system will be taken back and redone. If it still can't be improved, it will be disbanded immediately!" The head of the headquarters said with a sullen face.  It's straightforward.

    The leader of the surface-to-air missile force was shocked when he heard this, and quickly explained: "Chief, this air defense missile system is"

    "Okay, no need to explain!" Before the leader of the surface-to-air missile force could finish speaking, he was directly interrupted by the head of the headquarters: "The True Dragon 2 is just the lowest-end stealth aircraft. Even your system can't catch it. If one day  What will you do when a truly stealthy aircraft like the F-22 comes? Are you just waiting to be slaughtered?"
