Chapter 1087

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

Moreover, the aerodynamic layout design of fbc-1a fighter bomber does not have much impact on the flight quality of fbc-1a fighter bomber.

Take the maximum speed of fbc-1a fighter bomber for example. Thanks to the replacement of two more efficient wd-62suv medium thrust engines and the application of a large number of advanced lightweight materials such as aluminum lithium alloy, the maximum speed of fbc-1a fighter bomber can reach Mach 1.8.

Equipped with two inlet conformal fuel tanks, the aerodynamic performance is slightly affected, and the maximum speed decreases slightly, but it can still reach Mach 1.6.

You know, the prototype fbc-1 of the fbc-1a fighter bomber has a maximum speed of Mach 1.6.

In other words, equipped with two inlet conformal tanks capable of carrying more than 4000 liters of fuel, the fbc-1a fighter bomber is still as fast as the fbc-1.

As for other maneuverability indexes, the same is true. After all, the main task of fbc-1a fighter bomber is to attack the ground, and the air combat is only limited to self-defense, not a typical air fighter. Therefore, there is not much demand for maneuverability, so it is not a big problem to reduce it.

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

Because of this, the inlet conformal fuel tank has appeared, which has been highly praised by the chief engineer of fbc-1a fighter bomber. According to the aerodynamic design and internal structure of the inlet conformal fuel tank provided by Tengfei group, combined with the task expansion of fbc-1a fighter bomber, the research has been carried out for half a year, and then creatively put forward to use this kind of inlet conformal fuel tank Based on the characteristics of fbc-1a type fuel tank, it is extended to fbc-1a multi mission conformal mission cabin.

At that time, the chief engineer of fbc-1a fighter bomber, who put forward this view, just made a general concept. It was not so much an idea as a brain hole with good prospects.

Even his chief engineer doesn't know whether or when it can be done. Anyway, aviation theory research always has to go ahead of application research. If it can be done at some time in the future, maybe.

However, even the chief engineer of the fbc-1a fighter bomber did not have a clear frame, which aroused the interest of Zhuang Jianye.

We should know that Tengfei group is an important supplier of aero-engine, high-end aviation materials and basic theory design services in the next generation combat aircraft engineering. In other words, Tengfei group undertakes a large proportion of subsystem development of the next generation combat aircraft.

One of them is the overall structure of the next generation combat aircraft.

To this end, Tengfei group focuses on 3D printing technology, high-end laser manufacturing technology, precision welding technology, large-scale computer-aided design technology and other high-end technologies that Tengfei group can grasp to tackle this crucial core component of the next generation fighter.

After years of efforts, although great progress has been made in a certain area, some details are still unsatisfactory.

The most important reason is that the test equipment is not perfect, so that many theoretical values can not be obtained from reliable tests. For example, after the missile cabin is opened and the aerodynamic layout is changed, how to give consideration to the stealth performance?

What's more, how can the next generation combat aircraft overcome the erosion and damage of high-speed airflow to the interior of the bomb cabin when attacking at supersonic speed?

In addition, due to its particularity, the overall structure bomb cabin must be light and tough. That is to say, even if the bomb cabin has a large area, its weight must not be too high. Moreover, the structural strength of the overall structure bomb cabin must reach a certain degree, so as to achieve the best overall structure.

If we don't solve all these problems, the next generation of combat aircraft will only be a mirage. Let alone make it. It's still unknown whether the theory can 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 take-off group, who are the parents of the Americans. The United States is also indifferent. Who can make these key things the pillar of their aviation hegemony.

Since it is a pillar, it must be able to stand and not move.

As a result, even if Tengfei group is salivating, Americans are saying that where cool, where to stay.

Without advanced equipment, we can't be as efficient as the Americans.

What to do?

Zhuang Jianye's method is very simple, that is to take a quick run.

Tengfei group does not have the American high-end experimental equipment, test devices and experimental instruments, so that what can be solved in the laboratory can not cost more and take greater risks to do real flight test.

But even so, the overall structure of the capsule still can not be formed at one time.In that case, why do you have to be fat all at once? Isn't it the same to divide a large piece of meat into several small pieces and swallow it in one bite?

Because of the lack of such large-scale equipment and precision instruments, the large-scale overall structure bomb cabin with eight medium range air-to-air missiles can not be built in a short time, but the small bomb cabin take-off group with one small ammunition can not?

Although the difficulty is not small, it is not insurmountable for Tengfei group, which has been studying in this field for five years. What's more, for so many years, Tengfei group, together with several top domestic scientific research institutes and research institutions, has also made great progress in large-scale test equipment and precision instruments.

Although it is not up to the technical level required for the test of the large bomb chamber under the belly of F-22, a series of theoretical conditions for determining the small side bomb chambers on both sides are barely enough.

In that case, what else to say? Just brush the experience crazily.

It starts with the bomb compartment that can carry one small ammunition, and gradually increases to two or three until it reaches the design standard of the next generation of combat aircraft.

Just as Tengfei group used gas turbine to brush its experience in manufacturing aeroengine, it used practical application as a stepping stone to make up for its lack of experience.

The problem is that aeroengines can be brushed by gas turbines. What about the overall structure of the bomb cabin? Is it difficult to make an opening under the trj-500 regional airliner?

Don't say whether the troops will let them do it or not. Even if they agree, there is no practical operational demand. It's not enough to just make a cut.

The problem is that there are only a few types of aircraft in the army. Apart from the H6, there is no one who can use a knife in any part of the airframe.

Just after Zhuang Jianye and other engineers of Tengfei group racked their brains and couldn't come up with a good way, the chief engineer of fbc-1a fighter bomber sent such a brain hole without frame. What kind of model should be found to change the bomb cabin? The inlet conformal oil tank allocated by the chief engineer of fbc-1a fighter bomber is an excellent bomb cabin carrier to pump out oil?
