What's the use of showing off your own turbofan ten in front of Da Mao so ostentatiously?

Of course, it is to make Da Mao nervous so that they can come up with better things, otherwise, they will definitely be replaced by their own side.

Now, the effect has been achieved!

Hearing what Qin Tao said, Yemelyanov felt helpless: "Yes, in order to develop the fourth-generation aircraft, the Ryulika Design Bureau developed an AL-41F engine with a thrust-to-weight ratio of 11. This kind of

The engine uses a lot of advanced technology and is the best choice for fourth-generation aircraft. However, its size is larger and cannot be installed in our Su-27 fighter. Moreover, this engine actually has many technical problems.

There is no solution. Since the collapse of the Red Empire, the development of this engine has been stopped, and now, it is no longer possible to produce it."

After the collapse of the Red Empire, many projects stagnated or even started to regress. Take Third Uncle for example, the performance of the early versions imported from China was relatively stable, but later on, the quality began to decline, which shows that Lao Maozi's quality control

It's getting worse.

As for the advanced AL-41 engine, it is impossible to recreate it.

The maximum military thrust of this engine is 117.6 kN. There are many opinions on the maximum afterburner thrust, such as 175 kN, 181 kN, or even 196 kN. If this engine is installed on the Su-27, it will be perfect.

It can achieve supersonic cruise without afterburner, and can fly to Mach 2.5 with afterburner.

However, there is no longer the ability to produce this kind of engine, not to mention that it has not been fully developed in the first place.

"So what advanced engines do you have now?" Qin Tao asked.

"Currently, the Lyurica-Saturn Design Bureau is improving Third Uncle. They are developing the AL-31F-M1 engine, which can slightly increase the thrust of the engine, especially improves high-altitude performance and shortens its acceleration time.

"

In later generations, the new Su-35 was equipped with the 117S engine. This engine was actually a version that used some technologies of the AL-41F engine to improve the Third Uncle. However, the official research and development of this engine was already

In the 21st century, there is no such engine now.

The only version that improves the third uncle's version is still under development and will not be installed on aircraft until 1999.

In the past few years, Lao Maozi has really been treading water, even going backwards.

Qin Tao suddenly thought of something: "What engine is installed in the Su-35 you plan to sell to us?"

The modified Su-35S in the 21st century is equipped with the 117S engine. The current Su-35 is actually the Su-27M. What version of the engine is it using?

"This fighter uses the AL-35FM." Yemelyanov replied.

The current Su-35 actually planned to use the third uncle's, but the thrust was insufficient, so it switched to a new engine. As for the specific origin of this AL-35F engine, it is not clear, but the difference between it and the third uncle is that it has

The diameter of the engine inlet was enlarged to increase the amount of air intake, and the turbine inlet temperature was increased to increase the thrust of the engine. The internal structure was also slightly improved, thus achieving the goal of a maximum thrust of 8500kg and an afterburning thrust of about kg. Later, changes were made

The afterburner was adjusted to increase the afterburner thrust to kg. This is the famous AL-35FM. The only Su-37 uses the AL-35FM with a vector nozzle, also known as AL-37FU.

"Okay, then let's purchase this kind of engine." Qin Tao said: "This kind of engine has greater thrust than Third Uncle, and should be better than the turbofan X. If you are willing to export this kind of engine, then I dare to promise

, the quantity we purchase here will be at least 300 units, and possibly more."

This kind of engine is already their most advanced fighter engine. Can it be exported to the East? Yemelyanov felt a little uneasy.

That night, everyone stayed at No. 606 for dinner, and Mr. Zhang was still introducing everyone enthusiastically.

“After our engine is successfully installed, we can use its core engine to develop other engines. For example, if we put an outer bypass with a large bypass ratio, it can become a high-thrust turbofan engine.

, to meet the needs of our transport aircraft and bombers, and it will even be used on passenger aircraft in the future. We can also change it into a gas turbine for ship use, hoping to get an order from the Navy."

When foreign aircraft engines are developed, they first develop the core engine. After the core engine has no problems, they can then add external ducts to turn them into various engines. Although the turbofan 10 is developed according to the overall engine, as long as it is

The core machine can be taken out and used in other projects.

After hearing Mr. Zhang's introduction, everyone nodded: "Yes, we developed Turbofan X from scratch. This engine will definitely have a better future. We also look forward to it bearing fruit and becoming our domestic engine."

The most advanced and mature power."

These people talked very excitedly and left Yemelyanov alone. Yemelyanov drank alone and was unhappy. After a few glasses of wine, he actually became drunk.

When Lao Maozi was carried out, Mr. Zhang immediately put down his smile and looked at Mr. Lin seriously.

"This engine of ours has been approved and installed on a J-11 for testing. We thank the Air Force for its support. However, we do not yet understand the development rules of turbofan engines. Therefore, our engine is likely to be

There are some problems." Mr. Zhang said: "I hope the air force leaders can give us enough time to perfect this engine."

Countries have encountered big problems in the development of third-generation engines. The American F100 once broke down frequently, making the F-15 equipped with it the queen of the hangar. Lao Maozi's third uncle also continued to have problems during the research and development stage.

, so much so that the chief designer set up a reward program, awarding a certain amount of rubles for every gram of weight reduction.

This chapter is not over yet, please click on the next page to continue reading! After experiencing the failure of Turbofan VI in China, everyone has also realized the difficulties in the development of turbofan engines. Now it is about to be installed on aircraft for testing, and it is likely to explode.

There are so many questions. What if there are frequent failures and the Air Force loses confidence?

They have to agree in advance. Those remarks this afternoon are all for Lao Maozi. They themselves don't have much confidence.

Mr. Lin nodded: "Yes, we are mentally prepared for this. Anyway, I have my third uncle to make do with it for the time being. With President Qin's promotion, we may be able to import more advanced engines. Our Air Force can afford to wait until we have our own engines."

Mature up!"

"Everyone, Yemelyanov and I have already said hello. Their Su-35 fighters use the AL-35F engine, with a maximum military thrust of 8.5 tons and a maximum afterburner thrust of 14.5 tons. This engine gives

Replacing our fighter planes with them will definitely improve the performance of our fighter planes by leaps and bounds."

Hearing these rumors, Mr. Zhang felt a little aggrieved. What? Their maximum afterburner thrust is actually 14.5 tons? In this way, wouldn't the performance of our turbofan 10 fall behind again?

As if he knew what Mr. Zhang was thinking, Qin Tao said with a smile: "Mr. Zhang, don't worry, I believe that the engine we make ourselves can also achieve this kind of data. Come on everyone! Turbofan ten is related to

The several fighter jets of our naval and air force aviation units will never be discontinued."

Mr. Zhang finally breathed a sigh of relief.

A week later, the Sukhoi Design Bureau officially sent an invitation to guests from the East to go to the Gromov Test Flight Institute to appreciate the style of their Su-35 fighter jets.

After getting the news, Mr. Lin once again led the team, and a large group of people went to admire Lao Maozi's most advanced fighter jets with great interest.

"This is the most advanced fighter jet in our country. It is equipped with brand-new equipment. For example, its radar system has been upgraded to the latest N011 radar. It is the first airborne radar in our country that uses a flat-panel slot antenna.

Simonov, the head of the Sukhoi Design Bureau, introduced to the crowd enthusiastically: "Its appearance has greatly improved our combat capabilities. During the research and development stage, our goal is to track 20 targets.

And attacked 8 of them."

For a long time, the best thing about Lao Maozi's fighters is their maneuverability, and the most criticized thing is the backwardness of the electronic system. On the Su-35, these shortcomings have been made up for!

After repeated research, they finally solved the processing difficulties of the flat-plate slot radar antenna and have officially used this radar on the Su-35!

"Facing a bomber target, it has a detection range of 400 kilometers. When facing a target with an RCS of 3 square meters, its detection range can also reach 140 kilometers. Moreover, our fighter jet also deliberately has a detection range on the tail.

There is a rear-view radar installed inside the tail cone. If an enemy plane is pursuing it, the rear-view radar can detect it in time and at the same time, it can also guide our air-to-air missiles to attack behind."

This is also a unique function of the Su-27 series aircraft. Other aircraft simply do not have this capability.

Looking from the tail, there will be an extra tail cone in the middle of the two engines, just like the barb of a bee. It was originally the result of aerodynamic design, but the place at the tail can be used to install a rear-view radar, so that

It becomes the only fighter jet in the world with a rear-view radar. (It is also said that this thing is called a tail brace)

Everyone was surprised when they heard Simonov's introduction.

At present, the country has begun to use 1493 radar to replace the original bulky N001 radar. The radar with inverted antenna should have been retired long ago. However, the performance of this radar is not as good as the front!

Facing a transport aircraft, it can detect a distance of 400 kilometers and can chase 20 to eight times! When did Lao Maozi's technology become more advanced than our own?

"Mr. Simonov, your radar is indeed very advanced. Can you test it for us in a later performance? Especially this one of chasing 20 and playing eight."

Hearing Qin Tao's suggestion, the smile on Simonov's face became stiff: "Well, as you all know, we are currently short of funds. We took off twenty target drones at a time and shot down eight of them.

It’s too expensive for us.”

"If you are reluctant to spend money, you can transfer twenty target drones from our country." Qin Tao continued: "The consumption will be ours."

"Isn't this bad? How can I let you spend money?"

Mr. Lin was so shrewd that he immediately discovered something from the conversation between the two parties: the performance Simonov mentioned must have been exaggerated! That's why he didn't dare to test it.

"In that case, let's take off a transport plane and let's see how it detects a transport plane four hundred kilometers away." Mr. Lin joined the battle group.

The furthest search distance of the Yankee's AWG-9 radar is only 315 kilometers. The search distance of other fighters after that is not as good as this radar from 20 years ago. As for Lao Maozi's technology, it is absolutely impossible to compare with the AWG.

-9 Radar is strong.

"What we are demonstrating to you today is the maneuverability of this aircraft. Regarding the electronic system, we are only introducing it." Simonov continued to shirk: "We have not contacted the relevant transport aircraft as a target. Come on, everyone, go to the tail and you can see

Look at the engine of this aircraft. This is our most advanced AL-35FM engine with a maximum afterburning thrust of 14.5 tons. It makes our aircraft have an even better thrust-to-weight ratio and can do more maneuvers. If it is combined with a vector nozzle

, and can also perform many famous maneuvers.”

He originally planned to introduce electronic technology to make Easterners envious, but who would have thought that the other party would take it seriously and would not let go, so Simonov could only change the topic.

Mr. Lin and Qin Tao looked at each other and smiled. They already understood without saying anything.

In fact, although the N011 radar used a flat slot antenna, it was not mature at all. It was a semi-finished product. Therefore, Lao Maozi gave up after testing it and then improved it to a passive phased array radar antenna, which was called N011M.

The Snow Leopard radar used by the later Su-35S was a passive phased array system.

Everyone walked from the front of the plane, to the side, and then to the back.

The machine body still has the characteristics of an old machine, with exposed rivets. Although it has been repainted, it still looks like it has gone through many vicissitudes of life.

The Su-35 fighter planes are numbered from 701 to 710. The 11th one is 711, which is the Su-37.

However, these prototypes are not newly produced. For example, the 701, 702, 705, 706, and 707 fighters are heavily modified based on the mass-produced Su-27 fighter. Of course, as a test aircraft, it must have a test flight code, prototype No. 701

The official number is T-10M-1, which is the first prototype that first flew in 1988.
