"So, what do you think is an advanced bomber like?" Qin Guan asked General Lin.

Advanced bomber? General Lin looked at Qin Guan and said, "It looks like the Tu-160. In the area of ​​the bomber, I think the variable swept wings are not out of date."

Both B-54 and Tu-95 are old and twilight roles. Advanced bombers should be Tu-160 and B-1B. These two bombers are very similar in appearance. It can be seen that the designers of the two superpowers’ bombers We all reach the same goal by different routes.

However, because the Tu-160 bomber was born later, it is easy to use newer theories. For example, it not only uses variable swept wings, but also uses wing-body fusions. The entire aircraft comes from the front. Look, it's quite smooth. The whole fuselage is one piece. The nose is long and pointed. From the rear of the nose, the side strips stretch out. When the side strips go back, it becomes a wing box with variable swept wings. , Under the side strips, near the center of gravity of the aircraft, two engine nacelles are installed. Inside are four afterburner turbofan engines. The tail is retracted upwards and has a cross-shaped tail.

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

If you want to fly at an ultra-low altitude and penetrate defenses, then swipe the wing. If you want to take off and land, then spread the wing. In the air, the variable swept wing is perfect, except for the increase in structural weight. outer.

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

In the eyes of General Lin, this aircraft is the most advanced.

Hearing General Lin's words, Qin Guan shook his head: "No, no, you are wrong, General, your vision is very long-term, haven't you seen what kind of aircraft the future era belongs to?"

General Lin, you are already an old general who has mastered modern scientific concepts. 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!

"Future?" General Lin said, "The era of the future will be a stealth aircraft. You mean, our bombers will also become stealth aircraft? How can it be possible? The bombers are so huge, how can they be stealthy?"

If it is a stealth aircraft, then ultra-low-altitude penetration is not necessary. Ultra-low-altitude penetration is to avoid being hit by missiles at high altitudes, but in fact, as early warning aircraft become more and more common, ultra-low-altitude flight is not safe. , It is easy to be beaten.

The stealth plane is definitely the best, but it's a bomber. It's huge, many times the size of a fighter plane. How can it be stealthy?

Qin Guan smiled: "We can all make ships invisible. The size of the bomber is much smaller than that of the ship. General Lin, you must remember that there is nothing impossible, only unexpected. If we want to develop a bomber, It must be a stealth bomber!"

In the sky in the future, stealth aircraft can fly freely. Even bombers must have stealth capabilities. There is no doubt about this.

Qin Guan's suggestion was a stealth bomber. For General Lin, it would take time to accept it.

So big, can it be invisible?

"Are the fighter jets big? Didn't we still make the fighter jets invisible to the size of a ping pong 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. It should be known that once we have this weapon, it will be cross-age. Therefore, if we plan to build a bomber, we must build a stealth bomber. Well, in terms of time, now we should also set up a project. It’s similar to the previous booming plan, we don’t have to try again."

In fact, of course, the Air Force knows this shortcoming. The short-legged H6 cannot become the Air Force’s strategic bombing force. The Air Force used the H6 to improve the Spey engine to increase the range, but it eventually gave up because the gains were not worth the loss. A bomber code-named H-8 has been developed.

At that time, in order to reduce the development risk, the designers adopted the idea of ​​zooming in on the basis of the existing H-6, zooming in on the fuselage, and still using a swept-back mid-wing single-wing, round-section beehive-shaped fuselage. The fuselage has front and rear airtight cabins and rear equipment cabins. The middle section of the fuselage is a large bomb bay. It uses six Niu Country Spey engines. Later, it plans to use turbofan six so that it can be bombed from the mainland of Han. The bear country and the eagle country have gone.

However, due to the weak domestic technical force, this kind of magnified Bombardment finally disappeared. There are still only Bomber Bombers in China.

Now, does one need to continue to study this bomber? That's no longer needed. We have to aim at the advanced direction and directly mount the stealth bomber. If we want to cover people's ears, we can continue to call this stealth version of the bomber H8, and we can still exchange fakes for real ones.

General Lin nodded: "Yes, President Qin, your vision is the broadest. This stealth version of the bomber will be discussed within our Air Force. I will give you the results of the discussion as soon as possible."

The technical difficulty of this stealth bomber and the value it brings must definitely be debated within the Air Force. Now General Lin has already begun to look forward to this.

"Yes, we also need to make technical reserves in China." Qin Guan said: "Especially in terms of engines."

At present, the domestic backwardness in engines still exists. Only the large push and the middle push can be used, both of which are used for fighter jets. In the bomber engine, there is still a blank.

Bombers, fighter jets, and civil aviation engines are different.

The bomber's engine needs a large bypass ratio. After all, it can save fuel and have enough thrust. This seems to be similar to the airliner's engine. However, the bomber needs to have supersonic flight capability, such as the current picture. -160, B-1B, both have supersonic penetration capability. If you want to fly supersonic, you need an afterburner.

For example, Tu-160 is equipped with four Kuznetsov NK-321 afterburner turbofan engines with a maximum thrust of 137.3 kN and an afterburner of 245 kN. The weight of the engine is 3,400 kg and the thrust-to-weight ratio is 7.35. Look again, our most advanced turbofan X has an afterburner thrust of only about 120 kilonewtons, so the difference is almost doubled.

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