Why doesn t the new J 8 use a one piece windshield

Hello: Actually, I used to have the same expectations.

The latest improvements of Lao Qi have all used an integral windshield, and it stands to reason that the eighth master should also be improved.

But considering that the old seven is currently taking into account the export of sales, so do a beautiful point, you can also attract some poor buddies to buy, our own use is no longer to produce new batches of the old seven, just improve the current model, and withdraw to the second line, its life can be extended to elimination.

The eighth master export is no play, he is used as an interceptor, and this is enough at present, the tenth brother has been equipped in batches, and the fourth generation has also appeared, Shen Fei should have most of his energy on the f31, turning back and chewing the old grass, there is no taste.

Maybe in the future, I will see the latest improved Eight Masters, using the overall windshield, but it is impossible to equip it in large quantities, and it can only be the experimental version of the improvement direction of the current equipment model.

Because it is too expensive, China's current real overall hatch cover is only J20, and the others are not counted.

Moreover, the J8 pursues high-altitude and high-speed, and the integrated hatch only gives the pilot an almost omnidirectional vision, so the J8 does not have to pursue high speed, and generally requires a cross-subsonic bucket and a fighter with a ground attack.

And the J8 is basically the role of an interceptor.

At present, only the F35, F22, and J-20 in the world have adopted the design of the integral hatch; For the high-altitude and high-speed aircraft such as J-8, the strength of the overall windshield must be thick to meet the requirements, and the result is to increase the weight of the fuselage, and in the case of over-the-horizon combat, the horizontal bar will not have a great impact on the pilot's field of vision.

Due to the problem of the development of the J-7 process, the technology has been difficult to master for a long time, and the production and processing of some alloy materials have not been up to the standard for a long time. Later, due to safety issues, it was changed to the separation of the fixed windshield and the movable cockpit canopy, the cockpit canopy folded back and opened, and the transparent glass window behind the cockpit was replaced by metal skin, which is also a common feature of models after the J-7II.

Frame-mounted windshield? There are two reasons: 1. Our previous glass strength was not enough, and we couldn't do the overall arc windshield; 2. These aircraft are all high-speed, and the strength requirements of the front windshield are relatively high, especially the J-8. You see, the American F-14 is also such a windshield.

If you redesign it, you have to blow and change it in the wind tunnel, change it and blow it, and it's not as good as the ready-made one.

FBC-1 and J-8-2

If you look at the two aircraft from directly above, the most obvious difference is the shape of their wings. The J8 is a triangular wing with a large sweep angle, while the FBC-1's wing has a much smaller sweep angle. The shape of the wing is not triangular, but rather quadrangular in shape.

There are more differences when viewed from the side, first of all, their seat compartment, the J8 is a single-seater, and the FBC is a two-seater. On the back of the fuselage, the J8 has a straight back, while the FBC-1 appears more curved, like a hunchback. The J8's wings and fuselage are connected just below.

The FBC-1 is an upper wing. Leaning on the fuselage is higher.

In general, from the layman, it can be seen that the appearance of the J8 is a high-altitude and high-speed fighter, with a straight fuselage and thin wings. The FBC-1 is mainly used for bombing missions. More emphasis is placed on the large bomb load and long range. So the fuselage looks fatter.

J-8 Flying Leopard.

It's simple, look at the cockpit. The original design intention of the J-8 is to pursue high altitude and high speed, so the fuselage is slender, the cockpit is the same, and the position is very flat, and the appearance is almost the same as the J-7 MiG-21; The Flying Leopard mainly carries out ground attack missions, and the design refers to the style of mature attack aircraft such as the F15, and the cockpit position is significantly higher to ensure that the pilot has a good field of vision.

In addition, the slender body of the J-8 is easy to identify, and in comparison, the flying leopard appears to be "hunched over". The air intake duct is also one of the identification points, the air inlet of the J-8 is obviously rectangular, and there is a baffle at the part where the entrance is close to the fuselage; The flying leopard does not have this thing, and the shape of the 4 inner corners of the air intake is relatively sleek.

The J-8 is nose intake (J-8-2 is air intake on both sides of the fuselage), and the Flying Leopard is air intake on both sides of the fuselage. The J-8 is slender in appearance, and the Flying Leopard is thicker than the J-8. The J-8 is a single-seater, and the Flying Leopard is a two-seater.

The J-8 is a straight triangular mid-wing, and the Flying Leopard is a slightly drooping trapezoidal upper wing. In addition, there is a difference between the vertical tail and the horizontal tail appearance.

J-8 is good-looking, nicknamed the beautiful man in the air. Flying leopards are comparatively unsightly.

The flying leopard is also called JH7

Now equipped with several regiments.
