Chapter 1389 The Advantages of Industrial Waste (Second Update, Please Subscribe)
After the F104 "Star" fell from the sky like a lead block during the "Berlin Crisis", Aviation Industry Corporation became the biggest winner.

Not only did it win orders from Yugoslavia and traditional countries such as Israel, Argentina and Brazil, but it also received fighter orders from Western Europe!

Germany 132!
60 from the Netherlands!
Belgium 60!
Norway 30!
Switzerland 30...

Although the amount may not seem like much, it is still a breakthrough. After all, unlike the American aircraft they purchased using American aid under the "Joint Defense Program", these aircraft were purchased with "real money".

And this is just the first batch of orders. Last year, after the first batch of 10 F2 fighter jets were delivered to Switzerland, Switzerland placed an additional order for 24 fighter jets at the beginning of the year.

"…In terms of performance, our F2 fighter, although a light aircraft, has a complete radar system that is not inferior to the F4 fighter. It is not only highly maneuverable, but also has excellent ground attack capabilities. It is for this reason that it is welcomed by air forces of various countries…"

In the Tank Research Institute of Aviation Industry Corporation of China, when Kurt Tank was introducing to Li Yian how the F2 fighter was so popular in the market, he further introduced the modification of the F2 fighter, which focused more on the electronic systems, such as radar and other aspects.

After all, with the advancement of electronic technology, the performance of fighter radars is also constantly improving.

"Of course, although radar technology has made great progress, its current detection range is only 60 kilometers, which cannot meet the needs of long-range air defense. Therefore, the Air Force requires the development of a new airborne radar and the modification of the F4 fighter. Compared with our F2 fighter, the F4 fighter has a larger body, a larger payload, a longer range, and excellent maneuverability. It is definitely an extremely outstanding air combat platform!"

The concept of "air combat platform" is unique to the Air Force. In a literal sense, it is not just used for air defense, but a comprehensive, multi-purpose weapon. This is also the Air Force's requirement for fighter jets.

In fact, this is also forced by money.

Now, all over the world, there are attack aircraft for ground attacks, fighter jets for air combat, and even interceptors specially developed for air defense. It can be said that everyone has his or her own specialty.

But the problem is that developing each aircraft not only requires a large amount of research and development funds, but also requires the development of engines. In a word, the cost of "specialization" is money.

Not only the United States and the Soviet Union, but even Britain and France are like this. The reason they do this is due to traditional thinking and technological limitations.

Compared with them, the Air Force was influenced by Li Yian from the very beginning and developed multi-purpose aircraft based on fighter jets. Although it relied on breakthroughs in electronic technology, it basically achieved its goal.

But the foundation of the F2 fighter is there - a single-seat light fighter, not only its range is not inferior to that of heavy aircraft, but its combat effectiveness is also far behind.

Therefore, the F4 fighter jet from the United States became a supplementary option.

"Indeed, the biggest advantage of the F4 fighter is that it is large enough, which leaves more room for improvement!"

Li Yian said with emotion:

"In fact, this is also the advantage of large fighter jets."

Hearing what you said, Kurt Tank's eyes lit up and he said:
"Sir, I think that our next generation of aircraft should be a large twin-engine aircraft. Although it is expensive, its excellent performance cannot be concealed. Therefore, a large twin-engine aircraft is more in line with our needs."

"Double shot..."

Kurt Tank's suggestion made Li Yian nod slightly and said:

"Indeed, twin-engine missiles are theoretically superior to single-engine missiles in beyond-visual-range combat, sustained combat, multi-purpose capabilities, and survivability. The main advantage of single-engine missiles is in the early stages of combat and in some small movements that require agility..."

Although he agrees on the advantages of twin-engine aircraft, Li Yian has his own ideas:

"If the total thrust is the same, a twin-engine aircraft is not as good as a single-engine aircraft, because twin engines mean two sets of engine support structures, two sets of control and electrical systems, and the air inlet occupies a larger space. Then there are two engines - a 100-thrust engine is definitely lighter than two 50-thrust engines... and two engines lead to a decrease in roll rate due to the horizontal distribution of mass."

Because he had activated the "aircraft designer" function a long time ago, Li Yian was definitely not a layman when it came to fighter jet design. At the beginning, he firmly chose single-engine fighter jets, not only because they were cheap, but also more suitable for NBC's economy and for export. After all, when many countries purchase weapons, they not only consider performance, but price is also a very important factor.

"A twin-engine heavy fighter is good, but it is also very expensive. Double engines require double purchase and maintenance costs... The extra performance advantages need to be considered in terms of cost-effectiveness."

After rejecting Kurt's suggestion, Li Yian said:
"So, what we need to consider is whether we can develop an engine with greater thrust!" "An engine with greater thrust?"

"Yes, that's right!"

Li Yian nodded and said:
"The maximum thrust of a single J4 engine used in the F79 fighter is 7075 kg, and two engines only have 14 tons, while the maximum thrust of a single RW1 engine is 7335 kg. If our next-generation aircraft uses an engine with a thrust of more than 15 tons, it may not be as big as the F4, but it is definitely not a light aircraft."

One is as good as two!

This is truly the best solution. When Europe was developing the Typhoon fighter and France was developing the Rafale fighter, the reason why they chose the twin-engine solution was because of the engine performance. Although the EJ200 engine is the world's most powerful medium-thrust engine produced by the British Empire, its thrust is only 9000 kilograms. As for the M88 engine used in the Rafale, the thrust of a single engine is only 7500 kilograms.

Compared with the engines of the United States and the Soviet Union, European aircraft engines can be said to be extremely poor. It is precisely for this reason that in order to meet performance requirements, they developed the so-called "medium-sized aircraft". The other reason is that the engine thrust is insufficient.

"An engine with a thrust of 15 tons!"

Kurt looked at you in surprise, his eyes full of astonishment. He could hardly believe his ears and said:
"This, how is this possible?"

"How is it impossible? With a thrust of 15 tons and a thrust ratio of more than 7.5, the diameter can be a little larger, 1100 mm or even 1200 mm. Of course, the thrust ratio must be guaranteed. In any case, the resistance of one engine is definitely less than that of two engines, so the diameter does not need to be so strict."

When the RW1 turbofan engine was being developed, extremely stringent requirements were placed on the diameter. In order to give customers more choices when selling it overseas, the American J79 turbojet engine was also considered. Even the F2 fighter jet was tested using the J79. For this reason, its diameter was required to not exceed 1000 mm, while the corresponding Spey engine has a diameter of 1093 mm.

Although the requirements were stringent, the RW1 was eventually developed into a machine with excellent performance. It is not only lighter, but also has a thrust-to-weight ratio of 5.5. Except for the maximum thrust being slightly lower than that of the Spey, its overall performance far exceeds that of the Spey.

"Of course, this is just a suggestion. You can communicate with BMW in the future to develop such a high-thrust engine. The WP100-50 afterburning turbofan engine developed by BMW for the Global Express is an engine with a thrust of 14.5 tons! Although it weighs nearly 3 tons, it is not impossible to install it on a fighter jet!"

The famous MiG-31 fighter uses two D30F6 afterburning turbofan engines. In terms of thrust, they are a little bit smaller, but relying on the great power, it can not only cruise at supersonic speed, but also fly at Mach 2.83!
Although it is slightly slower than Mach 3, it is still very fast.

MiG-31... Thinking of this aerial behemoth with a maximum take-off weight of more than 46 tons, Li Yian couldn't help but think of its purpose - it is a typical interceptor, a defensive fighter, and is in the same group as large ground-based early warning radars and long-range surface-to-air missiles.

However, unlike ground-based radars and surface-to-air missiles that have to be installed at home, the MiG-31 also flies in the air to guard the home. It relies on its large body, a large radar, and several long-range air-to-air missiles with a range of more than 150 kilometers to scare people from a distance.

At first glance, the height and speed of the interceptor seem a bit intimidating. Even in the eyes of some people, it is just intimidating. In fact, there is no technical content. It is simply achieved by increasing the engine, the fuselage, and the fuel consumption. Therefore, the standard interceptor is very large.

Therefore, the interceptor is too large and has a high speed, resulting in extremely poor maneuverability, and is therefore not suitable for air combat. However... its function has never been to engage in air combat with fighter jets!
But intercept!

Intercept what?
Of course, during the Cold War, when everyone was ready to go all-in, they intercepted enemy bombers carrying nuclear bombs in the air! Occasionally, they could also use heavy long-range air-to-air missiles to fight with fighter jets.

This is the correct way to use an interceptor that looks like it has no use at all, or even like "industrial waste"!
He was never meant to engage in dogfights with fighter jets!
There is a correct way to open any type of aircraft!
If interceptors are "industrial waste", then the Soviet Union has such "industrial waste" and the United States also has such "industrial waste". During the Cold War, both countries relied on such "industrial waste" to protect their homes.

As for Britain, the oddly shaped "Lightning" fighter is an interceptor. The British never thought of using it to fight the MiGs. Its only use is to intercept Soviet strategic bombers!
"Ouch".

Li Yian, who finally figured out the purpose of the interceptor, couldn't help but have an idea in his mind... Since there is already a suitable engine, what if he uses it to make a "industrial waste"?

No, should it be said that it is a heavy interceptor that focuses on air interception?

Although we know that the possibility of a nuclear war breaking out in the future is very low, after experiencing the "Cuban Missile Crisis", it would be a lie to say that we are not worried.

Wouldn't such an interceptor be too expensive? Wouldn't it be a waste?
Just as Li Yian was weighing the pros and cons in his heart, Kurt said:

"Sir, we are currently researching a very powerful aircraft!"
