Born in the end of World War II, this engine design bureau is a famous aircraft engine design institution in the Soviet Union, the first chief designer Arkhip Mikhailovich Rurika, in 73 years, is already over 60 years old, but still presided over the most dazzling engine in the Rurika design bureau: AL-31 turbofan engine.

If you want a fighter to be able to fly successfully and meet the design requirements, the engine is absolutely the top priority, as a fighter that surpasses the F-15, the Soviet Air Force put forward strict requirements for the performance of the Su-27, after the hard work and continuous exploration of the technicians in the Rurika Design Bureau, finally, last year, the Al-31F engine was successfully finalized and equipped with the troops, and the chief designer finally saw the success of this engine before his death.

This high-thrust engine, with an afterburner thrust of 12,500 kN, gives the Su-27 a thrust-to-weight ratio of more than 1, which makes this fighter effortlessly climb vertically and make various maneuvers such as Cobra maneuvers, but the new chief designer Chepzin 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 from Iraq is simply a relief to them, in addition to the dismemberment of the fire control system of the F-14, the engine of the F-14 is also studied by the Rurika Design Bureau, in addition to this engine, there is another, that is, the engine of the Blackbird.

Blackbird in order to reach more than three times the speed of sound. It also permeates the painstaking efforts of American technicians, especially its engine, after disassembling these two American-made advanced engines at close range, Chepzin and others were very surprised, in addition to the integral front fan, the rear turbine blades, is what they sighed the most. This hollow turbine blade is very particular.

In the engine of an aircraft, the combustion temperature of the combustion chamber. The higher the temperature, the greater the thrust of the engine. But. There is a limit to the number of turbine blades that can withstand high temperatures at the rear of the engine, so finding high-temperature resistant materials and trying various cooling methods are the main means to improve engine performance for the development of engines. One of them is to make the turbine blades hollow, and then, in the process of operation, air is introduced into them. In the process of cooling the turbine blades, there is no reduction in power, but it is possible to increase the temperature that can be tolerated, which increases the thrust.

And this turbine blade in the United States is not just hollow. This turbine blade, which is made from porous laminates, consists of two pieces. The cooling air inside the interlayer must pass through a rather dense ingot-like labyrinth channel before it can be flushed out of the arrangement holes on the surface, this cooling process causes the air to form an air film around the metal blades, separating the blades from the high-temperature gas, and the blades with this divergence technology have the effect of convection, impact and air film cooling, and can withstand higher gas temperatures.

Soviet engineers broadened their minds. What they need is to find the right industrial processing methods and experiment with them to adopt these more advanced technologies, and the improved engine will have better performance.

With the start of the domestic aircraft carrier project, the improved version of the Su-27 will take off on the aircraft carrier, and in the case of the development of the supporting catapult is not smooth, the first Soviet aircraft carrier in the true sense, the Brezhnev, will only be able to take off by relying on the glide deck of the bow, in this way, the fighter's own performance, the more important it is, the greater the power of the fighter, the more it can take off with a greater take-off weight, which means that it can carry more fuel and ammunition. {{}}

History, under the impetus of Qusay, has begun to undergo various changes, for example, the classic generation of famous aircraft, Su-27, its improvement work, has been much faster than the progress of later generations.

In later generations, the Su-27M, the so-called Su-35, was officially launched only in the mid-nineties, however, the strapped Soviet Air Force, not a single one was ordered. [.] Now, its modification work has been much faster than that of later generations.

Important components of the fighter, engines, avionics, coupled with the body of the full-fledged Su-27, will inevitably enter a new period of development.

Simonov inspected the development of the radar, and found that the situation was very optimistic, and the experimental plane, which was converted from the An-12 transport plane, had already installed a new radar developed by the Instrument Manufacturing Research Institute on the nose, and when he saw it, this radar was being debugged and overhauled in preparation for the next test flight. {{}}

"Our radar has achieved various technical indicators proposed at that time, and, compared with the existing radar, it is about half the mass, and in the case of the same detection range and accuracy, the power is also reduced by half, reducing power consumption, in particular, this radar has a perfect downward and downward firing ability, even under the influence of clutter on the ground, it can accurately search for the target, and the cost, and the Su-27 existing radar is almost close." The head of the research institute told Simonov that as a supporting manufacturer, the relationship between the two sides is very friendly, almost an old acquaintance.

"Great, then we'll be able to equip a lot of equipment in no time, right?" Simonov said that on the way here, he had already heard that there was also a new breakthrough in the engine, and with the radar, the combat effectiveness of the Su-27 would go to a new 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 USSR itself? Simonov was very puzzled, seeing that the actual machine was in front of him, looking at the flat plate-shaped antenna, which was much lighter than the original upside-down lid and consumed much less power, but now, he heard the words of the developers.

"Chief designer, you also know that this kind of radar, the key is the gap on this flat plate, this gap will radiate out and the electromagnetic wave in space synthesize, in order to form a narrow beam in a certain direction, in this way to gather energy to make the radar see farther, without significantly increasing the volume and weight of the radar, a slight error, the electromagnetic field emitted from the gap will deviate from the expectation, so, the processing error of the entire waveguide gap must be controlled under high precision, our current processing conditions, can not be reached, so, Our imitations, including the radar solving computer have used their own products, only this flat slot antenna, we have tried to produce many, but, can not meet the accuracy requirements, now the test of this, with AG-9 own radar antenna. ”

The processing equipment of the USSR could not reach the accuracy of the United States, and now, the great Soviet Union is not even able to process such antennas! Simonov frowned, high-precision processing equipment, the West has. Since they can't process it themselves, it's better to simply 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'm afraid they won't give us an easy allocation, and besides, these equipment are forbidden to be sold to us in Batumi, and even if we have money, we can't buy it." The person in charge said that this idea had been in his mind, and then it was forgotten again.

Batumi is forbidden for sale? Simonov knew that the nature of a businessman was only for profit, especially in Japan. Five-axis linkage machine tool, this equipment used to process high-precision low-noise propellers, has already been secretly exported to the Soviet Union by Japan, those can be exported, this kind of equipment is lower than the five-axis linkage machine tool, there is definitely no problem with importing!

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, starting with the F-14, F-15, F-16, etc., began to use this advanced radar, and the USSR did not have it!

Simonov was 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 raising the level of our economy, especially the level of agricultural production, so that we can first achieve food self-sufficiency, so that our stores have sufficient goods, and not so many weapons, we have deployed so many nuclear warheads, but not even one of them has been launched!" The warships of our Navy have also been built one after another, and the aircraft carrier has just been launched, and the construction of a second one is about to begin! ”

Gorbachev's rise to power is absolutely inseparable from the support of Defense Minister Ustinov and Foreign Minister Gromyko, and these two people, although they also support Gorbachev's reforms, but they also attach great importance to the image of the Soviet Union, or rather, the military power of the Soviet Union.

Gorbachev was eager to take out the limited funds of the Soviet Union and invest them in economic reform, but after coming to power, he found it too difficult, because if he made any move, he would inevitably violate the interests of some people.

For example, before he came to power, he promised to give the GRU sufficient funds, but as a result, they increased their funding requests for the new year by 30 percent, and Gorbachev increased the funds for the GRU, and the KGB came to him, and the chairman of the KGB was also very supportive when Gorbachev came to power, and he could only persuade both sides to increase the funds by only 5 percent on the basis of last year.

USSR, there simply did not have enough money for reforms! That's because the existing system in the Soviet Union was problematic, and Gorbachev couldn't say these words directly to Ligachev, so he finally began to complain with the application signed by the chief designer of the Sukhoi Design Bureau.
