Chapter 1243 If you don’t face, it’s all right

  It’s just that many people in the industry still have a lot of reservations about the super Saiyan fit, and at most they admit that one plus one is far greater than two.

There is no way, it is because the entire J-8E multi-role fighter has long been separated from the basic framework of the J-8ⅡM fighter. Instead, the body of the J-8ⅡM has taken off with China after more than ten years, and many maturities have been achieved on the J-7MAX. The technology is combined to form today's J-8E multi-role fighter.

  Let’s talk about the wing of the aircraft, which is actually the layout of the side strip wing and the swept wing used on the latest improvement of the JJ-7MAX.

We must know that China Ascendas has studied this wing for ten years. From the initial side strip wing plus double delta wing layout, it was later found that the double delta wing was complicated and the high-altitude high-speed performance was poor, and it was changed to a more concise sweep wing; From the general swept wing to the highly maneuverable wing with the addition of leading edge slats; from the stiff transition between the side strip wing and the swept wing, to the smooth transition process.

Over the past ten years, Ascendas has invested a lot of effort and resources on this wing. Not only that, Ascendas also fully absorbed the airfoil used by the Russian Yakovlev Design Bureau on the Yak-130 advanced trainer. The successful experience of the company, and repeated verification of a series of wing configurations using the True Dragon series of demonstrators.

  Because of this, in the layout of side strips and swept wings, the Ascendas system not only does not lose to any domestic aviation research and production unit, but it is even faintly higher. After all, the accumulation of more than ten years is not a display.

  A similar situation is also the aero engine.

  The previous J-8II fighter used turbojet-13. The engine used in a typical second-generation combat aircraft not only has high fuel consumption, but also has an extremely short service life. The most important thing is that it has very poor low-altitude and low-speed performance.

This engine has also been used on the old JJ-7MAX. It is too clear what kind of urinary take-off system is. As soon as the WD-58ML turbofan engine on my side has matured, it has been decisively replaced, and the performance is immediately Improved a lot.

  So in the J-8E multi-role fighter, China Ascendas uses the mass-produced WD-58MVP turbofan engine based on the WD-58ML turbofan engine.

The cruise thrust is 5.8 tons and the afterburning thrust is 8.4 tons. Although it is only a medium-sized aero engine, the dual-engine linkage is sufficient to give the J-8E multi-role fighter with a maximum take-off weight of only 22 tons surging kinetic energy.

  Therefore, the J-8E multi-role fighter has the rare ground and air defense combat modes of domestic fighters.

  In the ground attack combat operation, in a high-low-high attack posture, the combat radius is 1,250 kilometers.

  With low-low-low and ultra-low altitude penetration posture, the combat radius is 780 kilometers.

  As for the air defense combat mode, the combat radius in the interception combat (supersonic) state is 478 kilometers; the combat radius in the normal air defense cruise (subsonic) state is 1460 kilometers.

Based on this, in typical air defense operations at key locations, the J-8E multi-role fighter can carry out air patrols for 2 to 2.5 hours over 800 kilometers from the base. In this state, it can conduct 10 to 15 minutes at any time. High-intensity air combat.

   Based on this alone, the J-7 has been far behind, even the basic model of the so-called J-8II fighter has been repeatedly crushed on the ground.

  Of course, this is only the average level of the J-8E. As a multi-purpose fighter, due to different missions, various indicators have changed, such as bomb load and fuel load.

  When attacking the ground, the J-8E has a classic load of 7.5 tons of ammunition and 4.2 tons of fuel.

In the    air defense interception combat mode, the bomb load is 5.3 tons, and the fuel load is 6.4 tons.

With a climb rate of 302 meters per second, a practical ceiling of 15,000 meters, and a maximum overload of 8 G, this typical heavy fighter with an empty weight of 10.3 tons and a wingspan of 8.6 meters cannot be said to be the best, but it is also It's definitely not a soft persimmon.

Of course, in terms of speed, the J-8E is much weaker than the J-8II fighter, from Mach 2.2 to Mach 1.8, and the practical ceiling is lowered from 20,000 meters to 15,000 meters, but the positioning of the two fighters After all, it is different. The J-8II fighter pursues high-altitude and high-speed, mainly used for interception; while the J-8E is a multi-purpose fighter with more comprehensive indicators.

  So in a sense, the two are not even fundamentally comparable.

   However, there is no comparability. As an improved version of the J-8 series, a lot of shadows can be seen on the J-8 on the J-8E. The most typical one is the body.

The main structure of the    has not changed significantly, and the slender and bee waist-like thick fuselage of the J-8II fighter is still used.

  It’s just that even if the body of the J-8II fighter is used, the J-8E as a whole is still regarded by some careful industry insiders as China’s take-off, an enlarged and improved version of the J-7MAX.

  Because whether it is the wings, air intakes, and the double tail fins under the tail of the fuselage, regardless of the highly recognizable fuselage of the J-8II fighter, it is actually the J-7MAX that is replaced by the fuselage.

However, many people in the industry don’t think so, because in a sense, the aircraft bodies of the JJ-7MAX and J-8II fighters have very deep roots, and they are both developed on the basis of the MiG-21. From this point of view, the J-8E is not so much an improved version of the J-8II fighter as it is the mass production version of the J-7MAX.

  This is indeed the case, because not only the wings, air intakes and aero engines, but also the integrated avionics system inside the J-8E is directly transplanted from the J-7MAX.

  Because the Yakovlev Design Bureau used in the JJ-7MAX, the integrated avionics system specially built for the Yak-130 advanced trainer is a simplified version of the Su-30 avionics system.

  China Ascendas acquired the Yakovlev Design Bureau that year, and naturally put this system into its own pocket without any burden.

   Now, under the premise that the domestic avionics system is not mature, it is natural to apply it to the J-8E.

Such as this, how can veterans in the industry dare to admit that there is a combination, even if one plus one is greater than two, it is a very euphemism~lightnovelpub.net~ After all, the one of the Ascendas system is very different from the one of Northeast Airlines Big.

  Only from Zhuang Jianye to ordinary employees. Ascendas China would rather be a combination of Super Saiyans, and would never say that it is an alternative and improved version of JJ-7MAX.

  After all, the Northeast Airlines Group is taking the lead. Even if Huangfeng needs reforms and introduces China Takeoff, it is not easy to do this too much.

You say this is the JJ-7MAX. The Northeast Airlines Group has nothing to do except the body and the vertical tail. Doesn’t that mean that you are holding the Northeast Airlines Group’s neck and slapped your face. You let the Huangfeng frame based on cooperation. Roast it on the fire.

  If this is the case, if the Northeast Airlines Group gets into trouble and messes up this matter, will it be a good opportunity for China to take off such an excellent fighter jet project and reap extremely high profits?

So the face-saving Zhuang Jianye and the Tengfei people don’t care at all. What they value is the actual number of orders, super high profit margins, and the opportunity to actually put the new models of the Tengfei system into service in the army. .

  Compared with these tangible benefits, whoever takes the lead and who is the boss is not a problem. As long as they can be taken down as good as they are, and the face is shameful, it will be fine!
