Chapter 2225: Conformal fuel tank

The advantages of composite pylons are many. For example, any hanging point has a maximum load limit. For example, the maximum load of this hanging point is 500 kg. Now it is equipped with a medium-range bomb, only 240 kg. , Then, it is a waste. If you add a composite pylon, and mount one on the left and right sides at the same time, you can just use the carrying capacity of this hanging point.
On the other hand, if it is a composite pylon, two launches at the same time are also easy to achieve.
However, this will definitely cause the internal interfaces of the pylon to be complicated, such as weapon interfaces, mechanical control interfaces, etc. If it is to hang a short-range missile, in order to cool the infrared seeker, a liquid nitrogen pipeline is also required. It is very complicated.
In fact, some fighters actually use composite pylons. For example, on the Tomcat fighter, there is a composite pylon at the wing root. In addition to hanging the Phoenix, it can also mount two Sidewinder missiles.
For F-15 fighter jets, due to some reasons during the design, missiles cannot be mounted on the outer section of the wings, so composite pylons are also mounted to increase the mounting capacity.
Of course, in normal training, I rarely see this kind of situation, and even most aircraft do not mount missiles. This is because I am afraid of trouble. The missiles must be checked before they are mounted. When they come back to the sky, they must be checked and confirmed. Re-stock in the warehouse intact. If you mount too many times, you are afraid of various unexpected problems. Therefore, you don’t have to hang up during training. However, in countries where fighting will break out at any time, there is an urgent need and it is possible to go up. Faced with complex situations, of course the more missiles you carry, the better.
In fact, there will be many problems with mounting missiles, and this will also involve trim issues. After mounting, the center of gravity of the aircraft will change. Generally speaking, the center of gravity will move back, and after the weapon is thrown, it will move forward. , The use of composite pylons, this situation is even more obvious, but as a low-cost high-performance weapon, the F-14 has a lot of innovations in its design, for example, the use of pitch control With the fly-by-wire control, the best compromise between cost and performance is achieved, and the balance can be solved by the fly-by-wire control.
"Of course, the composite pylon is a solution to the problem. In addition to this solution, there are others. For example, we can use conformal fuel tanks to free the pylons on the inside of the wings. In this case, During a long-distance attack, you can mount heavy weapons and still have enough range." Qin Guan said.
A better solution is conformal fuel tanks.
The inner wing pylon has the largest weight. For example, on a lightweight F-14 fighter, the inner pylon also has a load capacity of one ton. Normally, this is one thousand liters. The auxiliary fuel tank, plus the eight hundred liter auxiliary fuel tank in the belly, can carry an additional 2,800 liter auxiliary fuel tank on the entire aircraft, which significantly increases the empty time.
If the pylons inside the wings are freed, performance can be improved during long-distance attacks, even if it is the holy state-owned aerial refueling technology, such as long-distance air raids on targets in the territory of Baixiang Country, the fighters will still fly by themselves.
At this time, conformal fuel tank is the best choice.
At the same time, this also satisfies the needs of the Holy Nation. After all, for the Holy Nation, they need an advanced fighter, and at the same time they need a professional ground attack aircraft. The performance of the Thunder fighter is fully in line with their needs. Multifunctional fighter. 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 against the sky. You must know that even if it uses two similar mid-pumps, the Mi The plug-in capacity of Grid 29 is only two tons.
The lack of pylons of the current Raiden fighter severely limits its maximum mounting capability and also limits its operations in ground attack. Therefore, it is very important to liberate the pylon with the strongest internal mounting capability. Improved.
This is the upper conformal fuel tank.
The conformal fuel tank first appeared on the F16block60 model. This F-16 looks very strange. On both sides of the fuselage, there are extra triangular long-shaped bulges. On both sides of the fuselage, viewed from the front If it is, the upper part is almost flat, and the two devices are the conformal fuel tank.
Since it is a conformal fuel tank, it has been carefully designed. Generally speaking, it will not cause a significant drop in maneuverability. Of course, there must be a slight drop. 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 released and can mount various heavy weapons, such as ground attack ammunition, precision guided bombs, cruise missiles, etc. And so on, for example, heavy anti-ship missiles and so on.
Now, Qin Guan began to show on the spot, how to add this kind of conformal fuel tank, there is a skill, after adding, how will not affect the mobility, etc.
The commentary on the scene made Tu Lao all start looking at him with the most admiring eyes. 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 first of all, it should not be used on this type of fighter, but on a two-seater trainer.
When the F-14 fighter came out, Tu Lao and the others increased their confidence. They built a two-seater combat trainer that could train the pilots of three generations of aircraft. At the same time, they retained the single-seat combat capability. After all, this Advanced airplanes are only used to train pilots, which is too wasteful.
However, because the rear compartment is inserted, the fuel capacity in the aircraft is further reduced, which is quite unfavorable for this kind of small aircraft. Therefore, first, add this conformal fuel tank on the two-seater aircraft. It must be the best.
Try it after you go back!
After talking about the improvement of this aircraft, both parties are satisfied. Now, with this Dongfeng, General Jamal speaks again: "We hope this improvement can be carried out as soon as possible. First of all, the fastest way is to replace the composite pylon. Upgrade the fighter's fire control system to be compatible. For you, it will definitely be done soon. At the same time, we have another idea."
When General Jamal said this, he paused for a while, and then said: "Our F-16 fighter jet, I would also like to ask you to upgrade it. It can mount medium-range missiles so that it has medium-range combat capabilities. "
In fact, the F-16 fighter is a lap larger than the Raiden fighter. After all, it has a large thrust. The engine thrust is 12 tons. The engine thrust of the Raiden fighter is only 8 tons. Although a lap larger, this kind of aircraft, But there is no mid-range air combat ability, only fighting!
