Chapter 614: Inspection of Su-35

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 our 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 came up with the 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 jet. 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 began to regress. Take Third Uncle as an 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 even more impossible to recreate it.

The maximum military thrust of this engine is 117.6 kilonewtons. There are many opinions on the maximum afterburning thrust, 175 kilonewtons, 181 kilonewtons, or even 196 kilonewtons. If this engine is installed on the Su-27, it will be perfect. It can achieve supersonic cruise without afterburner and 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.

“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 improve the high-altitude performance and shorten 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 development of this engine has been In the 21st century, there is no such engine.

The only version that improves the third uncle 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 air 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 8,500kg and an afterburning thrust of approximately 14,000kg. Later, the afterburner was modified to increase the afterburner thrust to 14,500kg. This is the famous AL-35FM. The only Su-37 uses the AL-35FM equipped with vector nozzles, 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 , we will purchase at least 300 units here, 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 evening, 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 convert it into a gas turbine for shipboard use, hoping to obtain 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 frequently: "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 proven power.”

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

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

"Our engine 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 Some problems have arisen." 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 to reward a certain amount of rubles for every gram of weight he helped reduce.

 After experiencing the failure of Turbofan VI in China, everyone has also realized the difficulties in the development of turbofan engines. Now that they are being installed on aircraft for testing, more problems are likely to arise. What if there are frequent failures and the Air Force loses confidence?

They must agree in advance. The remarks made this afternoon are all for Lao Maozi, and they themselves do not 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 words, 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?

Seemingly knowing what Mr. Zhang was thinking, Qin Tao said with a smile: "Mr. Zhang, don't worry, I believe that the engines 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."

 Lao 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 admire their Su-35 fighter jets.

 After receiving 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, enthusiastically introduced to the crowd: "Its appearance has greatly improved our combat capabilities. During the research and development stage, our goal is to track 20 targets. And attacked eight of them."

 All along, 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!

"When 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. A rear-view radar is installed inside the tail cone. If an enemy aircraft 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 do not have this capability at all.

Looking from the rear, there will be an extra tail vertebra in the middle of the two engines, just like the barb of a bee. It was originally the result of aerodynamic design, but that place at the tail can be used to install a rear-view radar, so that It became the only fighter aircraft in the world with a rear-view radar. (There is also a saying that this thing is called a tail brace)

 Everyone was surprised when they heard Simonov's introduction.

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

Faced with transport aircraft, it can detect 400 kilometers away and can chase 20 to eight! When did Lao Maozi's technology become more advanced than ours?

“Mr. Simonov, your radar is indeed very advanced. Can you test it for us in a later performance? Especially this one of chasing 20 against 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 bring twenty target drones from our country." Qin Tao continued: "The consumption will be ours."

“Isn’t this bad? How can we let you spend money?”

 Mr. Lin is so shrewd that he immediately discovered something from the conversation between the two parties: the properties Simonov mentioned must be exaggerated! That's why he didn't dare to test.

“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. As for the electronic system, we are only introducing it." Simonov continued to shirk: "We have not contacted the relevant transport aircraft as targets. Come, 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 do many famous maneuvers.”

Originally he planned to introduce electronic technology to make Easterners envious. 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 is 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 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 plane is the 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 fighters. Of course, as a test aircraft, it must have a test flight code. The official number of prototype No. 701 is T-10M-1, which was the first prototype that first flew in 1988.

 At this time, what is displayed in front of everyone is the 707, which is a test aircraft built after the collapse of the Red Empire. The body is relatively new. If it were other aircraft, their condition would probably be even worse.

 The aircraft in front of me uses a different front fuselage, canards, and tail boom from the Su-27. However, the middle section of the fuselage, vertical tail, and wheels are all the same as the Su-27 mass-produced model. Everyone seemed to have a sense of intimacy.

Some people are already thinking in their minds. If this kind of aircraft is brought back and mapped by 601 Institute, it can be produced in Factory 112! It adopts a three-wing layout, which is much more maneuverable than the Su-27!

In fact, the Su-35 is just a Su-27 with an extra small wing. The original serial number of the Sukhoi Design Bureau was also Su-27M. Later, in order to better sell the aircraft, it was renamed Su-27. 35.

Just like the MiG aircraft, after the reputation of the MiG-29 became infamous, the Mikoyan Design Bureau made major changes to the MiG-29 and then named it the MiG-35. Unfortunately, it still failed to sell.

 In comparison, tanks are much better. The T-72 became notorious and was renamed T-90, and it really sold a large number of tanks.

After some in-situ inspection, it was the turn of the air show next. Pugachev put on his flight suit and walked out confidently. With the famous Cobra maneuver, he had become the world's famous The most famous test pilot, he has been flying the Su-35 for the longest time. He even flew the famous Su-37. He created many classic maneuvers on the Su-37.

 For him, this was just a normal flight show.

 After starting the engine, the beautiful three-wing fighter Su-35 slid onto the runway, took off with afterburner, and climbed at a high angle of attack. Various maneuvers were dazzling and dizzying.

The three-wing surface was originally used on carrier-based aircraft to improve the short-range take-off capability of the Su-33. However, after the Su-33 was developed, the Sukhoi Design Bureau became addicted to the three-wing surface layout. The Su-27 is equipped with canards and digital telex, which greatly improves its maneuverability.

Of course, there are costs, such as increasing the windward area, increasing the complexity of the operating system, etc. However, with an additional pair of control surfaces, more actions can be performed. Da Mao is still very satisfied with this change. .

At this time, everyone looked up and looked at the various maneuvers, and they could also feel the performance improvement compared to the Su-27.

"Everyone, the Su-35 is your best choice." Simonov said enthusiastically: "Please believe us, this fighter will not let you down! Although its price is 80 million US dollars, but , its performance feels worthy of the price.”

 The price negotiation has begun now!

 Eighty million dollars! When he heard this price, Mr. Lin's expression suddenly changed. This is a money grab. Your asking price is too high!

The domestically produced J-11 fighter jets currently cost 30 to 40 million US dollars each. If we purchase this kind of Su-35, 50 million or even 60 million US dollars per unit is acceptable, but Eighty million dollars a piece is ridiculously high!

“Is your price the price for the whole life?” Qin Tao asked with a smile: “For example, it includes a lot of after-sales service, including backup parts and even backup engines.”

"Of course not. This is the price of a single aircraft. You also need to purchase a series of advanced weapons. For example, we have equipped it with active radar-guided R-77 air-to-air missiles, as well as long-range R-77 missiles that can attack targets such as early warning aircraft. -172 missile, it can hunt down the enemy’s key targets at a distance of three hundred kilometers.”

 The Su-35 naturally needs to seize the market of the MiG-31. The two design bureaus have already been in love with each other during the Red Empire era.

The MiG-31, which was modified on the basis of the MiG-25, used a phased array radar for the first time. The search distance is longer, and the corresponding missile range can be greatly improved. For this reason, the Pennant Design Bureau The R-33 missile and the modified R-37 were developed. The latter has a range of 300 kilometers and is hung half-buried under the belly of the MiG-31, making the MiG-31 a sniper in the sky. .

The aircraft of the Sukhoi Design Bureau also perform homeland air defense missions and also have long-distance sniping capabilities. They use more advanced radars on the MiG-35, which of course requires more advanced missiles. They chose The R-172 (also said to be KS-172) missile of the Innovator Design Bureau, which appeared later than the R-37, uses more advanced technology.

The missile body is the same as the S-300. It is very simple. It has a two-stage engine and even a specialized ramjet engine. Later models even have a range of 400 kilometers. Of course, in order to circumvent export rules, the export product has been reduced to three Hundreds of kilometers.

These are the things that most impress the East!

Sure enough, after hearing these introductions, the eyes of Mr. Lin and others shone again.

 Modern air combat is inseparable from early warning aircraft, which are the brains and eyes of modern warfare. Therefore, when a war begins, killing the opponent's early warning aircraft has become an important combat task.

However, the other party must also know that the early warning aircraft is a high-value target and will definitely protect it well. It is really difficult to attack such an early warning aircraft.

Ordinary air-to-air missiles only have a range of tens of kilometers. Fighters have to get close to the early warning aircraft dozens of kilometers away to have a chance. At this distance, the opponent's **** fighters have already pounced on them.

 The only way to solve the problem is to throw weapons from a distance just like the navy does when attacking an aircraft carrier!

 The longer the range of the air-to-air missile, the better!

 Now, this kind of missile with a range of 300 kilometers can really become the killer of early warning aircraft. The other party will never expect that one's own side will launch missiles at a distance of 300 kilometers!

Even if you consider avoiding missing the target, if you get closer to 200 kilometers, the hope of success will be greatly increased.

This aircraft can really make up for our own shortcomings.

Seeing the look in everyone's eyes, Simonov knew that this deception had worked. The Su-35 was the best choice for Easterners, so even if it was more expensive, Easterners could still accept it!

This batch of aircraft will allow the Sukhoi Design Bureau to make a lot of money. Next, the Sukhoi Design Bureau will have more funds to develop fourth-generation aircraft. The shape of that fighter has just been made, and other There is still a lot of design work to do!

 The MiG 1.44 of Mikoyan Design Bureau is destined to be a failure!

The fighter plane completed the entire flight display and landed again. This time, everyone stepped up the gangway and looked at the layout inside.

As expected, Damao Watch Shop has disappeared. Inside the cockpit is a layout of four monitors, two on each side and two vertical monitors in the middle, forming a T-shaped layout.

"Everyone, this fighter is our most advanced aircraft, twenty years ahead of the Su-27 you are flying now. If it were not for our friendship, we would never sell such an advanced fighter to you." Simonov continued to be complacent.

If it were in the past, they would not sell it. After all, this is already the most advanced aircraft. But now, as they have started the research and development of the fourth generation aircraft, the importance of this aircraft is not high. Only by selling it can they make money. most important. How to develop research without money?
