Although in appearance, it is very similar to the MiG-29 of the Mikoyan Design Bureau, but if you look closely, you can still find the difference. Compared with the MiG-29, the body of the Su-27 is more slender, because it is A heavy air superiority fighter.

The easiest way to measure the quality of a fighter jet is to see it with your own eyes. A good plane is definitely a beautiful plane!From this point of view, the Su-27 definitely deserves to be number one.Anyone who sees it for the first time will be amazed by its majestic appearance.

You can’t see a pair of wings installed on the traditional cylindrical fuselage, and you can hardly see an abrupt line. The cantilever-style single wing has a smooth curved forward-extending side wing outside the wing root, which naturally aligns the machine The wings are fused to the fuselage, and the whole fuselage seems to be riding on two engines. With the four-redundant telex operation system, the performance of this fighter has met the strict requirements of the Soviet Air Force. More than, at least not less than the indicators of F-15!

In order to develop the Su-27, the Sukhoi Design Bureau has made arduous efforts, overcame many technical problems, and finally reached the original design target. Now, the Su-27 has entered the army in a small amount and has become the absolute best in the Air Force. Advanced fighter.

However, Simonov, who personally designed this fighter, still feels a little dissatisfied with the performance of the Su-27, especially the Su-27's radar!

Originally, at the very beginning, the Su-27 planned to use the SUV-27 radar of the Institute of Instrument Manufacturing in Zukovsky Town, using a planar slot antenna, surpassing the AN/APG-15 radar used by the F-63.However, due to the backwardness of electronic technology, the design institute has worked hard for several years, but still cannot solve a lot of problems. As a last resort, a simple enlarged version of the MiG-29 radar is used to achieve the design by increasing the antenna diameter and power. This has led to an increase in the number of electronic devices accommodated in the nose and an increase in the demand for power. The nose is too heavy but its performance is limited.

As an elite Simonov, he naturally wanted the Su-27 to have an advanced maneuverability radar that could match it!

"The chief designer, our request was rejected by Moscow." Idris Faizulin, the designer in charge of the avionics project, complained to Simonov.

got rejected?Simonov said: "Don't those senior officials in Moscow know that our current Su-27 is the only model that can fight against the F-15 fighter?"

"That's not true. Moscow feels that some of our improvements are too expensive. Our military expenditures are not enough to maintain such a high cost of fighter jets. It is said that Moscow is very short of money and is preparing to cut some budgets. We are good. Well, the newly appointed general secretary seems to be more tempted to reduce ballistic missiles."

"A country as powerful as ours is actually on the brink of economic crisis?" Simonov shook his head dissatisfied. He is not in charge of the economy, he is just an outstanding aircraft designer. There is a clue, it seems that the great Soviet Union is really not rich financially!

But why is the MiG-31 available?Simonov was still a little unhappy.

Idris knew that the chief designer was very dissatisfied with the practice of the Instrument Manufacturing Research Institute. Because they could not overcome the technical problems, they adopted the method of simply amplifying the antenna and power of the MiG-29, although the performance reached However, weight and power consumption are problems.

You must know that when designing the Su-27, the weight of each component was repeatedly considered. For this reason, a large number of titanium alloy components were used to reduce weight, but it was hindered by the radar.

Now, the Su-27 has been mass-produced, and its modification has also begun to be planned. In addition to the carrier-based type used by the navy, as an air-superior fighter, the avionics modification has always been put in the first place by Simonov. Therefore, He saw the MiG-31 radar!

After the MiG-25 was leaked because of Belenkov’s mutiny, this Soviet fighter, which was originally very powerful at three times the speed of sound, had to fade out of sight prematurely. On the basis of the MiG-25, the Soviet Union improved the MiG The Ge-31 interceptor is the new main interceptor.

The biggest change of this interceptor is that the nose is equipped with the first Soviet airborne NIPN007S-800 electronic scanning phased array fire control radar, which has a search range of 200 kilometers and can simultaneously track 10 targets and target 4 of them. Attacking a target, this kind of performance is simply abnormally powerful, and at the same time, the cost is also high, because this is the latest phased array system radar, and it is equipped with the R-33 long-range air-to-air newly developed by the Soviet Union. Air-to-air missiles can exert sufficient power.

Simonov searched for radars throughout the Soviet Union, and only this kind of radar could meet his needs. However, Moscow did not approve it, because the cost of such a radar was lower than that of the ten existing Su-27 radars. The cost is even higher!The Soviet Air Force can't afford it!

"The chief designer has just received news from the Radio Engineering Research Institute that their new airborne radar based on the AWG-9 radar is ready to be installed and tested for flight," Idris said.

"Really?" Simonov came to his senses immediately, "Let's go and have a look."

Simonov knew that the Soviet Union had secretly obtained a complete F-14 fighter. For this fighter, the most useful thing on it was the AWG-9 radar. This radar used a plane that the Soviet Union had never overcome technical difficulties. Slot antenna, whether the Soviet Union admits it or not, in this regard, the Soviet Union is indeed behind the times.

With this physical research object, because there is only one, the Instrument Manufacturing Research Institute and the Radio Engineering Research Institute, which have always been in a competitive relationship, unexpectedly cooperated with each other to overcome various technical design points of this radar, even all the The source code is still being deciphered, because when they are researching this radar, the software is also a difficult problem to solve.

Although the eastern powers are also working together with Iraqi technicians, and there is another comparable object, that is, the avionics of the F-20, but there is no doubt that the technical level of the Soviet Union is very powerful , they found solutions to many problems that they hadn't solved by analyzing Tomcat's radar. There are gaps in the flat plate, this gap reduces its own weight, but at the same time its performance has been greatly improved.

Therefore, the technicians of the Soviet Union took the lead in overcoming the difficulties of this kind of radar. They have developed an imitation of this kind of radar. Now, it needs to be installed on a special electronic aircraft for test flight.

The radar will not be directly installed on the fighter jet for test flight, because the radar needs to install various test equipment during the test. Therefore, a medium-sized transport aircraft carries this kind of radar on the head. This kind of equipment is the platform for testing radar.

Chapter 857 Technical Reserve of Super Flanker

Moscow, Rurika Engine Design Bureau.

Born in the engine design bureau just after World War II, it is a well-known aircraft engine design organization in the Soviet Union. The first chief designer Arkhip Mikhailovich-Lurika, in 73, was already more than 60 At an advanced age, he still presides over one of the most dazzling engines in the Rurika Design Bureau: the AL-31 turbofan engine.

If you want a fighter to fly successfully and meet the design requirements, the engine is definitely the top priority. As a fighter that surpassed the F-15, the Soviet Air Force put forward strict requirements for the performance of the Su-27. The hard work and continuous exploration of the technicians in the Ka Design Bureau, finally, last year, the AL-31F engine was successfully finalized and equipped with troops, and the chief designer finally saw the success of this engine during his lifetime.

This kind of high-thrust engine has an afterburner thrust of 12500 kN, which endows the Su-27 with a thrust-to-weight ratio of more than 1, which also allows this fighter to climb vertically without any effort, and perform various maneuvers such as cobra maneuvers. However, the new chief designer Chepjin is still not satisfied with the performance of this engine, and continuing to improve this engine, increasing thrust and reducing weight is their next goal.

In this case, the gift sent from Iraq is simply a timely gift for them. In addition to the F-14's fire control system being dismembered for research, the F-14's engine was also studied by the Lyurika Design Bureau. One engine, and another, the Blackbird engine.

In order to achieve more than three times the speed of sound, the Blackbird also infiltrated the hard work of American technicians, especially its engine. After dismantling these two advanced American-made engines at close range, Chepkin and others were very surprised. In addition to the integral front fan, the turbine blades at the back are what amazed them the most. The hollow turbine blades are very particular.

In an aircraft engine, the combustion temperature of the combustion chamber has a great influence. The higher the temperature, the greater the thrust of the engine.However, there is a limit to the turbine blades at the rear of the engine that need to withstand high temperatures. Therefore, for the development of engines, finding high-temperature-resistant materials and trying various ways to cool down are one of the ways to improve engine performance. primary means.Among them, one is to make the turbine blades hollow, and then, during the operation, air is introduced into the inside. In the process of cooling the turbine blades, no power will be reduced, but the temperature that can be tolerated can be increased. thereby increasing thrust.

The turbine blades in the United States are not just hollow.This kind of turbine blade made of porous laminate is composed of two pieces. The cooling air inside the interlayer must pass through a fairly dense ingot-shaped labyrinth channel before it can be rushed out from the arrangement of holes on the surface. This cooling process makes the air flow around the metal blade. A gas film is formed to separate the blades from the high-temperature gas. The blades using this divergent technology have the effects of convection, impact and gas film cooling, and can withstand higher gas temperatures.

The Soviet engineers broadened their thinking. What they needed was to find suitable industrial processing methods and conduct experiments to adopt these more advanced technologies. The improved engines would have better performance.

With the launch of the domestic aircraft carrier project, the improved version of the Su-27 will take off on the aircraft carrier. In the case that the development of the supporting missile launcher is not smooth, the first Soviet aircraft carrier in the true sense, the Brerìnev , will only rely on the bow of the ship to take off over the deck. In this case, the performance of the fighter will become more and more important. More fuel and ammo.

History, under the impetus of Qusay, has begun to undergo various changes. For example, the improvement of the Su-27, a classic model of later generations, has been much faster than that of later generations.

In later generations, the Su-27M, also known as the Su-35, was officially launched in the mid-90s, but the struggling Soviet Air Force did not order a single one.Now, its remodeling work is much faster than the progress of later generations.

The important components of the fighter, such as engines and avionics, coupled with the mature Su-27 airframe, will inevitably enter a new period of development.

Simonov inspected the development of the radar, and found that the situation was very optimistic. The experimental aircraft modified from the An-12 transport aircraft had already installed a new type of radar developed by the Instrument Manufacturing Research Institute on the nose. When he saw At the time, this radar was being debugged and overhauled, preparing for the next test flight.

"Our radar has achieved the various technical indicators proposed at that time, and it is about half lighter than the existing radars. With the same detection distance and accuracy, the power is also reduced by half. The power consumption is reduced. In particular, this radar has perfect downward-looking and downward-shooting capabilities. Even under the influence of ground clutter, it can accurately search for targets, and the cost is the same as Su- 27 The existing radar is almost close.” The person in charge of the research institute told Simonov that as supporting manufacturers, the relationship between the two parties is very friendly, almost old acquaintances.

"Great, then we will be able to equip a large number of equipment immediately, right?" Simonov said. On the way here, he has heard that the engine has also made new breakthroughs. Coupled with radar, the combat effectiveness of the Su-27 will increase. Take it to the next level.

"Chief designer, we only have this radar now," said the person in charge.

"What do you mean? Isn't this radar produced by our great Soviet Union?" Simonov was very puzzled. Seeing the real aircraft in front of him, he saw that the flat antenna was lighter than the original inverted pot lid. More, and the power consumption is much smaller, but now, I heard the words of the developers.

"Chief designer, as you know, the key to this kind of radar is the slit on the plate. This slit combines the radiated electromagnetic waves in space to form a narrow beam in a certain direction. In this way Concentrate energy to make the radar see farther without significantly increasing the volume and weight of the radar. If there is a slight error, the electromagnetic field emitted from the gap will deviate from the expected one. Therefore, the processing error of the entire waveguide gap must be controlled within Under high precision, our current processing conditions are still not up to it, so our imitation products, including the radar calculation computer, all use our own products, only this flat-panel slot antenna, we have trial-produced several, but , can’t meet the precision requirements, and the current test is still using the AWG-9’s own radar antenna.”

The Soviet Union's processing equipment can't reach the precision of the United States. Now, the great Soviet Union can't process this kind of antenna!Simonov frowned. The West has high-precision processing equipment.Since they can't process it themselves, they might as well import processing equipment from abroad.

"We can report to our superiors and import from abroad," Simonov said.

"Our country's foreign exchange reserves are very tight. I am afraid that we will not allocate funds easily. Moreover, these equipment are prohibited from being sold to us in Batumi. Even if we have money, we cannot buy them." The person in charge said, this Thoughts, had been in his mind, and then were thrown out of his mind.

Batumi banned for sale?Simonov knew that the nature of a businessman is to seek profit, especially Japan.The five-axis linkage machine tool, this kind of equipment used to process high-precision and low-noise propellers, has already been secretly exported to the Soviet Union by Japan, and those can be exported. This kind of equipment is lower than the five-axis linkage machine tool. Import is definitely no problem!

As for the funds, it is really a problem. It seems that I have to lobby the senior officials in Moscow. The new radar is very necessary and scarce for the Su-27.The United States started using this advanced radar from the F-14, F-15, F-16, etc., and the Soviet Union has not yet!

Simonov is very confident.

"Why do we need to have every weapon that the United States has?" Gorbachev said to Ligachev very dissatisfied: "Now, the focus of our country should be on improving our economic level, especially in agriculture. The level of production allows us to achieve food self-sufficiency first, so that our stores have sufficient goods, instead of having so many weapons, we have deployed so many nuclear warheads, but we have not even fired a single one! The warships of our navy, One after another is also built, the aircraft carrier has just launched one, and the second one is about to be built!"

Gorbachev's coming to power is absolutely inseparable from the support of Defense Minister Ustinov and Foreign Minister Gromyko. Although these two people also support Gorbachev's reforms, but, But it also attaches great importance to the image of the Soviet Union, or in other words, the military power of the Soviet Union.

Gorbachev really wanted to take out the limited funds of the Soviet Union and invest in economic reforms, but after he came to power, he found that all this was too difficult, because as long as he made a move, he would definitely offend certain people. people's interests.

For example, before he came to power, he promised to give the GRU sufficient funds. As a result, they increased the funding application for the new year by 30.00%. Gorbachev increased the funding for the GRU, and the KGB When I found it, the chairman of the KGB was also very supportive when Gorbachev came to power. He could only persuade both sides. On the basis of last year, the increase was only 5.00%.

The Soviet Union, simply did not have enough money to carry out reforms!That's because there is a problem with the existing system in the Soviet Union. Gorbachev couldn't tell Ligachev what he said directly, so he took the signature of the chief designer of the Sukhoi Design Bureau The application finally started to be sent to jail.

Chapter 858 Lebanon Seaside Scenery

Up to now, Ligachev is still Gorbachev's most trusted friend. Hearing Gorbachev's words, Ligachev was also very touched and said: "Yes, our military expenditure is simply It’s like a bottomless pit, taking up too much of our expenditure, and if it weren’t for the stable oil price this year, we might have to borrow more foreign debt from Europe.”

It seems like a joke that the powerful Soviet Union actually relied on foreign debts to keep its people from starving. However, in the Soviet Union, this actually happened.The military industry of the Soviet Union occupies too many national resources. These military industries are of no help to improve people's living standards. Those are cold weapons and have nothing to do with people's lives.Now, the main pillar of the Soviet Union's economic income is oil. It is simply incomprehensible that a powerful country needs to rely on selling oil to survive.

However, what makes the two of them even more depressed is that they know that military expenditures account for too much of the GDP, and they invest too much in national defense, but they can't come up with a better way, because reducing expenditures will cause Under pressure from all sides, no one wants to have enough budget, and everyone wants more funds. The pressure from all the elders is very great.
