    Such a streamlined conformal fuel tank that extends from the outer wall of the inlet to the wing root not only has a loading capacity of 2180 liters of fuel, but two tanks can produce an additional 4000 liters of fuel, which is enough to increase the range of the FBC-1A fighter-bomber by 30%.  .

    And the design that fits the aerodynamic layout of the FBC-1A fighter-bomber does not have much impact on the flight quality of the FBC-1A fighter-bomber.

    Take the maximum speed of the FBC-1A fighter-bomber as an example. Thanks to the replacement of two more efficient wd-62suv new medium-thrust engines and the application of a large amount of advanced lightweight materials such as aluminum-lithium alloy, the FBC-1A fighter-bomber  Able to reach a maximum speed of Mach 1.8.

    Equipped with two inlet conformal fuel tanks, the aerodynamics are slightly affected, and the maximum speed is slightly reduced, but it can still reach Mach 1.6.

    You must know that the maximum speed of the FBC-1, the prototype of the FBC-1A fighter-bomber, is only Mach 1.6.

    In other words, after being equipped with two inlet conformal fuel tanks that can carry more than 4,000 liters of fuel, the FBC-1A fighter-bomber is still as fast as the FBC-1.

    The same is true for other mobility indicators. After all, the main mission of the FBC-1A fighter-bomber is ground attack, and air combat is limited to autonomous defense. It is not a typical air worry fighter, so it does not have much requirements on mobility. Therefore,  It doesn't matter if it's lowered.

    On the contrary, this conformal fuel tank can not only increase the range of the fbc-1a fighter-bomber, but more importantly, it fits perfectly with the fuselage, so that the fbc-1a fighter-bomber can improve its combat effectiveness as much as possible without affecting its own flight performance.  .

    Because of this, the inlet conformal fuel tank has appeared, and it was immediately highly praised by the fbc-1a fighter bomber commander. Then based on the aerodynamic design and internal structure of the inlet conformal fuel tank provided by Ascendas Group, combined with the fbc-1a fighter-bomber commander,  The mission expansion of the 1a fighter-bomber itself was studied for half a year, and then it was creatively proposed to use the characteristics of this inlet conformal fuel tank to expand it into the fbc-1a fighter-bomber multi-mission conformal mission cabin.

    The FBC-1A fighter-bomber chief who proposed this idea at the time only made a general concept. It was more of a promising idea than an idea.

    Even he, the chief engineer, doesn¡¯t know whether it will be possible or when it will be possible. Anyway, aviation theory research always takes a step ahead of applied research. It might happen in some time in the future.

    However, even the FBC-1A fighter-bomber commander did not have a clear framework of imagination, but it aroused Zhuang Jianye's interest.

    You must know that Ascendas Group is an important supplier of aero engines, high-end aviation materials and basic theoretical design services that are the core of the next-generation combat aircraft project. In other words, Ascendas Group is responsible for a large proportion of the sub-systems of next-generation combat aircraft.  research and development work.

    One of them is the overall structural bomb bay of the next generation combat aircraft.

    To this end, Ascendas Group has concentrated on 3D printing technology, high-end laser manufacturing technology, precision welding technology, large-scale computer-aided design technology and other high-end technologies that Ascendas Group has available to tackle this crucial core component of the next-generation fighter.

    After years of hard work, although great progress has been made in certain aspects, some details are still unsatisfactory.

    The most important reason is that the test equipment is imperfect, so that many theoretical values ??cannot be obtained from reliable tests. For example, after the bomb bay is opened and the aerodynamic layout is changed, how can the stealth performance be taken into account?

    Also, at supersonic speeds, how can next-generation combat aircraft overcome the erosion and damage to the interior of the bomb bay caused by high-speed airflow when attacking?

    Furthermore, due to its particularity, the overall structure bomb bay must be light and tough. In other words, even if the bomb bay is large in area, the weight must not account for too high a proportion. Not only that, the structural strength of the overall structure bomb bay must be  It must reach a certain level so that the overall structure can be optimized.

    If all these factors are not resolved, the next generation of combat aircraft will only be a mirror image, let alone a prototype. It is still unknown whether the theory can even take shape.

    However, most of the precision instruments and equipment used to test these data are in the hands of the Americans. Not to mention your Ascendas Group, they are the fathers of the Americans. The beautiful country also ignores them. There is no way who can let these key things be  The backbone of their aviation supremacy.

    Since it is a pillar, of course it must be able to stand and cannot be moved.

    So, even if Ascendas Group is almost salivating, Americans just say, wherever it is cool, stay there.

    Without advanced instruments and equipment, there is no way to do it with the same efficiency as Americans.

    what to do?

    Zhuang Jianye¡¯s method is very simple, that is, run quickly in small steps.

    Ascendas Group does not haveWe must prepare high-end experimental equipment, testing devices and experimental instruments like Americans, so that things that can originally be solved in the laboratory must not cost more and bear greater risks for real flight tests.

    But even so, the overall structure of the bomb bay still cannot be formed in one go.

    If that¡¯s the case, then why do you have to eat a fat man all at once?  Isn't it the same as breaking a large piece of meat into several small pieces and swallowing it in one bite?

    ??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Because it does not have such large equipment and precision instruments, it cannot be built for a while, but the Tengfei Group can¡¯t build a small-sized bomb bay to load a small ammunition?

    Although this difficulty is not small, it is not insurmountable for Ascendas Group, which has been researching in this area for five years, not to mention that Ascendas Group has cooperated with several top domestic scientific research institutes and research institutions over the years, and has been engaged in large-scale  Test equipment and precision instruments have also made great progress.

    Although it has not yet reached the technical level required to test the large bomb bays under the belly of the F-22, it is still barely enough to determine a series of theoretical conditions for the small side bomb bays on both sides.

    Since that¡¯s the case, what else can you say? Just gain experience like crazy.

    Start with a bomb bay that can load one small ammunition, and gradually increase it to two or three bombs, until it reaches the design standards of the next generation of combat aircraft.

    Just like Ascendas Group used gas turbines to build aerospace engines and gain experience, it used practical applications as a stepping stone to make up for its lack of experience.

    The problem is that the aircraft engine can be brushed by relying on the gas turbine, but what about the overall structure of the bomb bay?  Is it possible to open a hole under the TRJ-500 regional airliner?

    "Don't talk about whether the army will allow this to be done. Even if it is agreed, there is no practical operational need and it is not enough to just open the mouth.

    The problem is that there are only a few types of aircraft in the army. Except for the H-6, there is no model that can use knives on any part of the body.

    Just when Zhuang Jianye and other engineers from the Ascendas Group were racking their brains and couldn't come up with a good idea, the chief engineer of the fbc-1a fighter bomber sent such an idea without a framework. What kind of aircraft model could be used to modify the bomb bay? fbc  ¡ªThe inlet conformal fuel tank attached to the 1a fighter-bomber chief division, wouldn't it be an excellent bomb carrier if the fuel is evacuated?
