Chapter 2225

The composite hanger has many advantages. For example, any hanging point has the maximum load limit. For example, the maximum load of this hanging point is 500kg. Now it carries a medium-range bomb, which is only 240kg. Then, it is a waste. If you add a composite hanger, mount one on the left and right sides at the same time, It just makes use of the bearing capacity of this hanging point.

On the other hand, if it is a composite pylon, it is also easy to launch two at the same time.

However, this will certainly lead to the complexity of the internal interface of the pylon, including weapon interface, mechanical control interface, etc. if it is to hang a short-range missile, in order to cool the infrared seeker, it also needs to have a liquid nitrogen pipeline inside, which is very complex.

In fact, in fact, some fighters use composite pylons. For example, on the male cat fighter, there are composite pylons at the wing root. In addition to the undead birds, they can also mount two rattlesnake missiles.

For some reasons in the design of F-15 fighter, missiles cannot be attached to the outer section of the wing, so composite pylons are also attached to increase the mounting capacity.

Of course, this kind of situation is rarely seen during normal training. Even most aircraft do not mount missiles. This is because they are afraid of trouble. Missiles should be checked before mounting. When they come back from heaven, they have to check and confirm that they are intact before warehousing. If they are mounted more times, they are afraid of various unexpected problems. Therefore, they do not hang up much during normal training, but, In countries where fighting will break out at any time, there is an urgent need. They may face complex situations. Of course, the more missiles they carry, the better.

In fact, there are many problems with mounting missiles, which also involves the problem of trim. After mounting, the center of gravity of the aircraft will change. Generally speaking, the center of gravity will move back, and after throwing weapons, it will move forward, and the composite hanger is used. This situation is more obvious. However, as a low-cost and high-performance weapon, There are many innovations in the design of the j-14. For example, in the pitch control, the telex control is adopted, which has achieved the best compromise between cost and performance. The trim can be solved by telex control.

"Of course, composite pylons are a solution to the problem. In addition to this solution, there are other solutions. For example, we can use conformal fuel tanks to liberate the pylons inside the wings. In this way, we can mount heavy weapons and have enough voyage during long-distance attacks," Qin Guan said.

A better solution is conformal fuel tank.

The weight of the wing inner pylon is the largest. For example, on the lightweight j-14 fighter, the inner pylon also has a loading capacity of one ton. Under normal circumstances, there is a 1000 liter auxiliary fuel tank. With the 800 liter auxiliary fuel tank on the belly, the whole aircraft can carry an additional 2800 liters of auxiliary fuel tank, significantly improving the empty time.

If the pylon on the inner side of the wing is liberated, the performance can be improved during long-distance attacks. Even if the holy state-owned air refueling technology, such as long-distance air strikes on targets in the white elephant country, the fighters still have to fly by themselves.

At this time, conformal fuel tank is the best choice.

At the same time, it also meets the needs of the holy country. After all, for the holy country, they need an advanced fighter. At the same time, they need a professional ground attack aircraft. The performance of lightning fighter is a multifunctional fighter that fully meets their needs. Although the maximum take-off weight of this fighter is less than 13 tons, its maximum plug-in has reached 4.5 tons. This data is quite contrary to the sky. You know, even if two similar zhongtui are adopted, the plug-in capacity of MIG 29 is only two tons.

The lack of pylons in the current lightning fighter seriously limits its maximum mounting capacity and its operation in ground attack. Therefore, it is a very important improvement to liberate the pylons with the strongest mounting capacity on the inner side.

This is the upper conformal tank.

The conformal fuel tank first appeared on the f 16block 60 model. This F-16 looks very strange. There are many triangular strip shaped protrusions on the fuselage on both sides. On both sides of the fuselage, if viewed from the front, the top becomes almost flat. The devices on both sides are conformal fuel tanks.

Since it is a conformal fuel tank, it is carefully designed. Generally speaking, it will not cause a significant decrease in mobility. Of course, there must be a slight decrease. After all, the shape has changed.

In the most professional terms, it is called roughly maintaining the original air combat capability. At this time, the inner pylon is liberated and can carry all kinds of heavy weapons, such as ground attack ammunition, precision guided bombs, cruise missiles, etc., such as heavy anti-ship missiles, etc.

Now, Qin Guan began to make on-site comparisons. How to add this conformal fuel tank is a skill. After adding it, how will it not affect mobility, and so on.

The on-site explanation made Tu Lao begin to look at him with the most appreciative eyes. President Qin's professional knowledge is simply too rich. He is also a very powerful designer in the field of military aircraft.

His method is quite good, but it should not be used on this kind of fighter, but on a two seat trainer.

When the j-14 fighter came out, Tu Lao's confidence greatly increased. He also built a two seat combat trainer, which can train pilots of three generations of aircraft. At the same time, he also retained the single seat combat capability. After all, this advanced aircraft is only used to train pilots, which is too wasteful.

However, because it is plugged into the rear compartment, the fuel load in the aircraft is further reduced, which is quite unfavorable to this small aircraft. Therefore, first of all, adding this conformal fuel tank on the two seater aircraft must be the best.

Try it when you get back!

After finishing the improvement of the aircraft, both sides were satisfied. Now, taking advantage of the east wind, general Jamal said: "we hope this improvement can be carried out as soon as possible. First, the fastest way is to replace the composite pylon and upgrade the fighter's fire control system to be compatible. For you, it must be done soon. At the same time, we have another idea."

When general Jamal said this, he paused and said, "our F-16 fighter also wants you to upgrade it. It can mount medium-range missiles and make it capable of medium-range combat."

In fact, the F-16 fighter is one lap larger than the thunder fighter. After all, it has a big push, with an engine thrust of 12 tons. The engine thrust of the thunder fighter is only 8 tons. Although it is one lap larger, this aircraft has no medium-range air combat capability and can only fight!
