Chapter 1298 All for the sake of invisibility

Previous page        Return to Catalog        Next page

    Not only Prince Salman was so surprised that some of his speech was not coherent, but Abdullah and others who came with him also looked at the FC-21 fighter jets in front of them, their eyes widened with disbelief on their faces.  .

    You must know that during the afternoon display, the fc-21 fighter jet, not to mention the stealth bomb bay, even the semi-buried weapon rack under the belly was very rough. Because of this, China Takeoff only announced the fc-21 at that time  The reflection area of ??the front radar of a fighter jet does not explain the more important radar reflection area data below the aircraft body at all.

    You must know that the frontal radar emission area is only suitable for air combat, while the radar reflection area under the belly is mostly used for ground-to-air air defense requirements.

    Because of this, the true omnidirectional stealth required by the fourth-generation aircraft is not how small the individual frontal radar cross-section is, but that the radar cross-section of the aircraft body does not exceed 1 square meter from any angle.

    This is also the fundamental reason why combat aircraft like the Rafale can only be positioned as third and a half generations rather than fourth generations at most. No matter how small the frontal radar reflection cross section is, the omnidirectional radar reflection of the entire aircraft is doubtfully large.  life, and in aviation operations, aircraft not only face air-to-air combat from opposing fighters, but also face the threat of surface-to-air weapons. The frontal radar cross-section is small, and it can hit accurately from another angle. Such a combat aircraft will never be able to  Can't be called invisible.

    This was the case with the fc-21 fighter jet shown in the afternoon. Although the semi-buried weapon mount effectively reduced the radar reflection cross section on the front, it did not help the radar reflection cross section under the belly. On the contrary, the complex configuration of the air-to-air missile caused radar reflection.  The area has been expanded three times.

    This can be seen from the fact that after the fc-21 fighter jet caused a sensation, when His Majesty the King of the United Arab Emirates personally flew the aircraft to experience it, the UAE air defense force used radar to track the entire process. The area illuminated by the radar of the peripheral escort fighter jet is indeed 0.45 square meters, but  The air defense force's radar strikes from the bottom up, mainly targeting the belly and flanks of the aircraft. The radar reflection cross sections of these two parts are 1.2 square meters and 1.6 square meters respectively.

    Although this value is still not very large compared to other models, and can even be called excellent, it is undeniable that a fighter aircraft exceeding 1 square meter cannot be called a stealth aircraft, which means that the battlefield of the fc-21 fighter  Survivability is not as exaggerated as Zhuang Jianye said.

    At best, it is better than the old second-generation aircraft, and slightly inferior to some third-generation aircraft with integrated electronic warfare modules. After all, today's radars are extremely sensitive, especially those of traditional military powers such as the United States and Russia.  The new generation of air defense missile system launched is basically accurate for 1 to 2 square meters of aircraft such as the fc-21 fighter jet.

    To be honest, if it weren't for Zhuang Jianye speaking in front of the King of the United Arab Emirates and patting his chest to ensure that the ultimate goal of the fc-21 fighter jet is a true fourth-generation aircraft, it would now be in an initial state that has not fully evolved.  Coupled with Prince Abdullah's private matchmaking, His Majesty the King reluctantly continued the negotiation. Otherwise, based on the UAE King's love for French equipment and the poor performance of the FC-21 fighter jet in front of highly sensitive air defense radar, it would have been long ago.  Cool.

    Because of this, without Shi Jun¡¯s special issue, just based on His Majesty the King¡¯s feelings and the tracking tests of the UAE Air Defense Force, the price of the fc-21 fighter jet cannot be that high. After all, as Prince Salman said, they  There are really too many choices. If the FC-21 fighter jet has nothing to impress the hearts of the UAE, no matter how rich the UAE is, it is impossible to throw money into it with eyes closed. After all, the UAE's money does not come from the strong wind.

    I just didn't expect that just a few hours later, the fc-21 fighter jet, which originally had no omnidirectional stealth at all, would be completely destroyed because of the two stealth bomb bays placed under the wings and highly integrated with the entire aircraft.  The shotgun was replaced with a cannon, thus possessing preliminary omnidirectional stealth capabilities.

    This leap is not unpowerful, but what shocked Prince Salman even more was that the FC-21 fighter jet did not fully release all its capabilities in public displays.

    What does this mean?

    The fc-21 fighter jet still has great potential to be tapped!

    "We only open this set of under-wing stealth bomb bay components to real friends!" Just as Prince Aleman and others were confused, Zhuang Jianye lost no time in speaking, and immediately walked a few steps to the fc-21 fighter jet.  He reached out and patted the one on the left wing of the heavy load pylon that had opened the hatch, revealing the stealth bomb bay with medium-range air-to-air bombs inside, and continued: "I've said it before, no one knows better than me.  Regarding aviation products, of course, it is impossible for me to display everything most of the time. Firstly, time is limited. Secondly, and the most important reason is that some things are too sensitive. If I really show them all, it will definitely cause an uproar.

    In order to prevent some malicious businessmen from takingThe FC-21 fighter jet has been hyped up, and several special issues have been published to slander us. They simply concealed the status of the high-configuration model and only opened it to real partners who are interested in purchasing or cooperating.  "

    As he said that, Zhuang Jianye raised his eyes and looked at Prince Salman and Prince Abdullah, the smile on his face became stronger: "Obviously, the arrival of you two showed me the sincerity of your country, so I resisted domestic pressure  We would like to disclose to you the top-end version of our fc-21 fighter jet. It is also the only combat aircraft among the three generations of aircraft with omnidirectional stealth function. At this point, the division of three and a half generations is no longer enough to define the top-end version of fc.  ¡ª21 fighter, so we separately classify it as a 3.8-generation fighter, which means it is infinitely close to the fourth-generation fighter"

    Zhuang Jianye's words were extremely sincere, and coupled with his eloquent eloquence, Prince Salman was stunned for a while. Prince Abdullah on the side wanted to remind his nephew who suddenly gained a high position.  Don't be fooled by Zhuang Jianye.

    But when he saw the two stealth bomb bays that were originally on the heavy-load pylons quickly retracted under the control of ground personnel, the reminder that came to his lips was swallowed by Prince Abdullah.  go.

    It was not visible before unfolding, but the entire effect of retracting is completely revealed. The entire pylon fits the wing very well. If you don't look carefully under the wing, you can't tell what the two stealth bomb bays are.  Based on the position of the self-loading pylon, one would think that the two bomb bays are designed to be integrated with the wings.

    Because of this, the cross-section of the entire bomb bay is very small. From a distance, it is just a slight bulge under the wing, as if the wing blade on the second-generation aircraft is installed backwards.

    But it is completely different from the Wing Knife. The entire bomb bay has been treated with very good stealth. Even though it is only a small bomb bay, Abdullah can fully appreciate what Zhuang Jianye said before.  : "The biggest feature of the design of our fc-21 fighter jet is that everything is for stealth, and everything else is just a cloud."

    Now that the facts are in front of you, why do you ask Prince Abdullah, who values ??face and truth more than life, to say this?
