Eagle Sauce: The 055 destroyer was launched into the sea just after the founding of the country?

Because the wings can be adjusted and deflected at an angle, the aircraft's shock wave drag can be reduced during flight.

以F-14和F/A-18为例，F-14的最大飞行速度可以达到2.38马赫，而F/A-18却只有1.8马赫。

From this, it is not difficult to see that the F-14's penetration capability is significantly better than that of the F/A-18 carrier-based aircraft, which is basically due to the variable sweep wing.

The variable swept wing not only allows the aircraft to gain high speed advantage at high altitudes.

At the same time, during slow-speed flight, such as takeoff and landing, the swept wing allows the wing to be swept back at a smaller angle.

This increases lift at the leading edge of the wing, improving the aircraft's stability and overall efficiency.

However, this variable sweep wing technology is not without its drawbacks.

Although, the wings of aircraft using this design can be deflected backwards, thereby reducing drag and improving penetration capability.

But the problems it brings are serious problems such as high maintenance cost and complex structure.

In terms of design, the inner wing section of the variable sweep wing aircraft is fixed, and the outer wing is connected to the inner wing with a hinge shaft. The outer wing is rotated back and forth by a hydraulic booster to change the rearward rubbing angle of the outer wing section and the aspect ratio of the entire wing.

Such a design makes the structure complex, significantly increases the weight, makes it very difficult to operate, has a relatively high failure rate, and the maintenance cost is much higher than that of similar aircraft.

What's worse is that this design will destroy the stealth capability of the aircraft.

In future air battles, if an aircraft does not have stealth capabilities, it will face fifth-generation fighters such as the F22 and J20.

No matter how strong these aircraft's penetration capabilities are, they are nothing more than a piece of cake for the enemy...

Fang Yu was not unaware of the various shortcomings of the variable sweep wing.

But he still chose the Backfire strategic bomber that adopted this technology without hesitation, and he had his own considerations.

First, Fang Yu had no choice.

When the project was first launched, Fang Yu had considered manufacturing subsonic bombers such as the H-6, Tu-95, and B-52.

After all, although these bombers are slow and even a bit old, they were still used by the Eagle, the Bear and the Dragon in the era in which he lived.

This is enough to show the reliability of these veterans.

But, Fang Yu only reacted later.

The reason why these countries still use these veterans who have served for fifty or sixty years is not because of their strong combat capabilities.

It is because these countries have developed a new type of bomb.

Take the Long Kingdom’s H-6 bomber for example.

After modification, this bomber can even carry DF21 missiles.

Although he is slow and has no invisibility effect.

But all he had to do was fly to a distance of 1000 to 2000 kilometers from the enemy and launch the DF21 under the plane.

The remaining one or two thousand kilometers are enough to penetrate the defense by relying on the DF21 missile itself.

The same is true for Figure 95 and B52.

Whether it is equipped with a Dagger missile or an AGM86 missile, it can strike the enemy outside the enemy's air defense zone.

It is precisely because of this that these old guys still have their place in the new century.

In my era, let alone a weapon as powerful as the DF21.

Even the DF5B, a road-based missile, has not been developed by the Long Kingdom.

In order to bomb the empire, you must have your own bombers fly over the enemy's cities and drop bombs.

Therefore, strategic bombers like the H-6, which are slow and non-stealth, were directly passed over by Fang Yu.

After all, no matter how poor the F86 fighter's capabilities are, it can still be used to deal with Master Liu...

Fang Yu is not unwilling to manufacture a weapon like the B2 that is stealth, capable of supersonic cruise, and has a huge payload.

Rather, whether it is based on the current industrial level or economy of Longguo.

None of them can meet the requirements for manufacturing B2.

Moreover, it is obvious that even if the B2 bomber can be built, its performance is obviously exceeded.

These days, many countries don't even have basic air defense radars.

The B2's stealth capabilities are also purely flirting with the blind...

So, after excluding the old and the most advanced bombers.

There are only a few bomber models left to be manufactured.

Among them, whether it is the White Swan of Figure 160 of the Russian Bear.

It’s still the B1B Lancer of the Eagle Sauce.

It also uses variable sweep wing technology and is essentially no different from the Backfire strategic bomber that they want to manufacture.

Moreover, compared with the high manufacturing prices of these two strategic bombers.

The manufacturing price of Backfire is still within Fang Yu's acceptable range.

If mass production is carried out, the price can be further reduced.

In fact, in Fang Yu's eyes, the other shortcomings mentioned above are not shortcomings at all.

High maintenance cost? Complex structure? High failure rate?

so what?

The P38 Thunder propeller fighter has a simple structure, almost no maintenance cost, and an alarmingly low failure rate.

Basically, there is no one who doesn't like this aircraft.

But, with his frail body, snail-like speed, less than 200 kilometers of range, and several hundred kilograms of payload, is it possible for him to drop Dragon Country's mushroom bomb on the Eagle Sauce?

impossible!

What I want to build is not other weapons, just something that can be used.

Strategic bombers are always the country's most important weapons!

It is the last resort to safeguard national security and deter enemy countries!

Why talk about maintenance costs, complex structures, and high failure rates for such a national weapon?

As long as he can steadily drop Dragon Country's mushroom bombs over Eagle Sauce's cities, these shortcomings are not shortcomings at all!

Indeed, it is true that this Backfire bomber does not have stealth capabilities.

However, its maximum flight speed reaches an astonishing Mach 2.3!

At the same time, it also has an astonishing maximum bomb load of 24 tons!

At such a terrifying speed, even if the Eagle Sauce discovered the existence of Backfire, what could it do?

With the F86's extreme speed just exceeding the speed of sound, they couldn't even see the Backfire's tail flame and could only watch as the Backfire threw them off with a burst of afterburner.

Then he watched in despair as his city was reduced to ruins by the explosion of mushroom bombs!

You don't even have to actually do it.

All I have to do is build this plane and fly it over the United States.

From now on, I'm afraid the Eagle Sauce will never dare to clamor for a surgical strike on the Dragon Kingdom again...

Of course, all this is a story later.

What I have to solve now is the manufacturing problem of variable swept wings.

As mentioned before, one of the disadvantages of variable sweep wings is that their structure is very complex.

Although the inner wing section is fixed, the outer wing and the inner wing must be connected by a hinge axis.

This places very high demands on the strength of the hinges and the connecting parts between the outer wing and the inner wing.

Moreover, these parts must not only be strong but also light enough.

However, judging from the current situation in Dragon Country, Fang Yu has not yet found a material that possesses both of these properties...
