Super Weapon Swap System

"Then, what do you think of the advanced bombers?" Qin Guan asked general Lin.

Advanced bombers? General Lin looked at Qin Guan and said, "it's like Tu-160. In the field of bombers, I don't think the variable sweep wing is out of date."

The B-54 and TU-95 are already the roles of old age. The advanced bombers should be Tu-160 and B-1B. These two bombers have very similar shapes. It can be seen that the bombers designers of the two superpowers have the same goal by different paths.

However, since the Tu-160 bomber was born later, it is also easy to use the updated theory. For example, it not only uses variable swept wings, but also uses wing body integration. From the front, the whole aircraft is quite smooth. The whole fuselage is integrated, with a pointed nose. From the nose backward, it is an extended edge strip, and the edge strip is backward, At the same time, under the edge strip, near the center of gravity of the aircraft, there are two engine nacelles, in which there are four afterburner turbofan engines, the tail shrinks upward and has a cross shaped tail.

This design has also been analyzed by countless military experts. The use of variable swept wings is mainly to combine the characteristics of long range, long endurance and large weapon load of bombers with low altitude high subsonic and high altitude hypersonic penetration capabilities. This is the only way.

If you want to fly at ultra-low altitude and make penetration, sweep back the wings. If you want to take off and land, expand the wings. In the air, variable sweep wings are the most perfect, in addition to increasing the structural weight.

There are now variable swept wing fighters in China. It should be possible to expand on this fighter and develop a similar bomber, right?

In general Lin's eyes, this kind of aircraft is the most advanced.

Hearing general Lin's words, Qin Guan shook his head: "no, no, you're wrong, general. Your vision is very long-term. Haven't you seen what aircraft the future era belongs to?"

General Lin, you are an old general who has mastered the concept of modern science. How can you be so short-sighted? When you encounter problems, you should look forward, not backward!

Those bombers belong to the past, not the future!

"The future?" general Lin said, "the future era is stealth aircraft. Do you mean that our bombers will also become stealth aircraft? How can it be? Bombers are so huge, how can they be stealth?"

If it is a stealth aircraft, there is no need for ultra-low altitude penetration. Ultra-low altitude penetration is to avoid being beaten down by missiles in high-altitude flight, but in fact, when early warning aircraft are becoming more and more common, ultra-low altitude flight is not safe and easy to be beaten.

Stealth aircraft must be the best, but it's a bomber. It's huge and many times larger than a fighter. How can it be invisible?

Qin Guan smiled: "we can all make ships invisible. The volume of bombers is much smaller than ships. General Lin, you should remember that we can't do it. We can only think of it. If we want to develop bombers, we must be an invisible bomber!"

In the future sky, stealth aircraft can fly smoothly. Even bombers should have the ability of stealth. There is no doubt about this.

Qin Guan's suggestion is stealth bomber, which takes time for general Lin to accept.

So big, can you be invisible?

"Is the fighter big? Don't we still make the stealth of the fighter the size of a table tennis ball?" Qin Guan said to general Lin: "Don't doubt our technology. As long as we can think of it, we can do it in the future. You should also know that once we have this kind of weapon, it will be cross era. Therefore, if we plan to build bombers, we must build stealth bombers. Well, according to the time, we should also set up a project now. It is similar to the previous scheme of eight bombing, We don't have to try again. "

In fact, of course, the air force knows this kind of weakness. The short legged bomb six can not become the strategic bombing force of the air force. The air force once used the bomb six to improve the Spey engine to improve the range, but it finally stopped because the gains outweighed the losses. At the same time, the air force has also developed a bomber code named bomb eight.

At that time, in order to reduce the development risk, the designers adopted the idea of enlarging the fuselage on the basis of the existing bombardment VI, and still used the swept back middle single wing and round cross-section bee waist fuselage. The fuselage had front and rear sealed compartments and rear equipment compartments, and the middle section of the fuselage was a large bomb compartment, which used six NiuGuo Spey engines, and later planned to use turbofan VI, which was from Han Dynasty If you take off from China, you can bomb bear country and Eagle country.

However, due to the weak domestic technical force, the amplified hong-8 finally has no following, and there are still only hong-61 bombers in China.

Now, do you still need to continue to study this kind of bomber? That's no longer necessary. If you want to aim at the advanced direction, you can directly mount a stealth bomber. If you want to hide people's eyes and ears, you can still call this stealth bomber "hong-8" for real.

General Lin nodded: "yes, Mr. Qin, your vision is the most open. This stealth bomber will be discussed within our air force. I will give you the discussion results as soon as possible."

The technical difficulty and value of this stealth bomber must be debated within the air force. Now general Lin has begun to look forward to it.

"Yes, we also need technology reserves at home," Qin Guan said, "especially in the engine."

At present, the domestic backwardness in engine still exists. Only large push and medium push can be used, which are used for fighters. In terms of bomber engine, it is still blank.

Bombers and fighters, civil aviation engines, are different.

The bomber engine needs a large bypass ratio. After all, it can save fuel and have enough thrust. It seems to be similar to the aircraft engine. However, the bomber needs to have supersonic flight capability. For example, the current Tu-160 and B-1B have supersonic penetration capability. If you want to fly at supersonic speed, Then you need an afterburner.

For example, figure-160 is equipped with four Kuznetsov nk-321 afterburner turbofan engines, with a maximum thrust of 137.3 kn and an afterburner thrust of 245 kn. The engine weight is 3400 kg and the thrust weight ratio is 7.35. Let's take another look at our most advanced turbofan 10. The afterburner thrust is only about 120 kn, so it's almost twice as bad.

Such an engine is really a blank in China. If you want to develop this bomber, you have to study the engine first.
