Chapter 199 The once firm belief collapsed

   "Your Excellency Nikolai, welcome to our design bureau to inspect the work." Alexander Yakovlev extended his hands enthusiastically: "We also welcome visitors from the East around you."

   "It's very presumptuous to bother you." Qin Tao said to Alexander: "I heard that you have a famous Yak-141 here, and its various data exceeds the existing Yak-38 by a large margin, so let's come and have a look."

  Anyway, I’ve already said hello, and I’m going to name you, just to see Jacques-141.

   "Of course no problem, please come with us, our prototype is currently undergoing static tests."

Aircraft design is scientific, and all kinds of experiments must be done. A slight negligence will lead to disaster. The 601 Institute developed the J-8. The prototype aircraft was just installed, and it caught fire during the test run, and the entire aircraft was burnt down. After tossing for more than half a year, it was discovered that a fuel pipe of the engine had resonated, and it was abruptly broken, and then the leaked fuel encountered an open flame, causing a catastrophe.

The static test is to check the ability of the aircraft to resist pressure, how much each part can withstand, and whether it can meet the requirements. After all, the parts on the aircraft cannot be made as strong as possible. Strength, but not too heavy, depends entirely on static tests to resolve this contradiction.

This is the first time that everyone has seen Jacques-141. Although there are many pillars under it and many suspenders on it, it looks like it has been pierced by thousands of arrows, but because it is suspended, it can be seen Clearly.

  Everyone looked up at the plane with anticipation in their eyes.

   "Generally speaking, the creation of a static testing machine means that the entire design has been frozen. With the Soviet scientific research level, it may be finalized in two or three years." Qin Tao said.

If there is no crash, they can go to the air show, but now, the only thing they can see is this one. Of course, what Qin Tao said is for Lacourt, even if Lacourt I can't understand Lao Maozi's words, but his adjutant will seriously record everything he hears and sees, and then write a report.

  Alexander nodded: "Yes, according to our advance development plan, it will be successfully finalized in the last few years."

  He can only say insincere words, and this is true, according to their pre-plan, the plane should be finalized now, but unfortunately, no one cares!

"I always think that this vertical take-off and landing method is the most perfect." Qin Tao continued to flicker: "Sea Harrier, the engine is placed in the middle, so that the space at the rear of the aircraft body is wasted, and, The nozzles are on both sides, which causes a loss of power. Now, the main engine is at the tail, and the afterburner can be arranged. The power of the engine is strong, so that the aircraft can have high enough performance."

Whether it is the Sea Harrier or the Yak-38, there is no afterburner. The combustion chamber at the tail of the engine extends the nozzles to both sides, just like the two legs of a baby. Can't live.

   Now, although the static test aircraft does not have an engine installed, the position has been reserved, and the structure of the entire aircraft can be seen clearly. The main engine at the back and the lift engine at the front are all so real.

Gu Lao is carefully looking at the layout of the entire aircraft. From the nose, it looks like a MiG-25, the foundation of a second-generation aircraft. As for the main wing, it can be seen that it can still take advantage of the latest aerodynamic achievements. Under the huge air intake, Gu Lao looked at it for a long time and yearned for it.

  When the model of their J-8 was changed, it was mainly to change the nose, from the air intake of the nose to the air intake on both sides.

   This is the gap!

   "We have also engaged in vertical take-off and landing aircraft before, but due to the insufficient power of the engine, we can only use the engine to drive the fan to achieve vertical take-off and landing." Gu Lao said.

  In the era of the J-6, it was too difficult to take off and land vertically. After all, the thrust-to-weight ratio of the aircraft at that time did not exceed 1.

  Thrust-to-weight ratio is the ratio of engine thrust to aircraft weight. If the ratio exceeds 1, it means that the aircraft can climb vertically by relying on its own power. If it is lower than 1, it will lose altitude.

  At present, there is no domestic aircraft that can achieve this. The thrust-to-weight ratio of the J-6 is 0.86, which is already against the sky. The emergency dispatch capability is very strong because of the powerful engine.

But it is still very difficult to lift the plane from a static state. At that time, the No. 4 plane built by 601 used the gas from the main engine to drive four large fans. The big fan, that shape, is absolutely unique in the world.

  Why just hang a fan?

This can be seen from the difference between a turbojet engine and a turbofan engine. The core engine of a turbofan engine is equivalent to a turbojet engine, and an external duct is installed on the outside, and the engine drives the fan to jointly provide thrust.

  The engine blows air directly backwards, which is smaller than the kinetic energy of the engine driving the fan, and then the fan blows air backwards. Therefore, the power is increased and the fuel consumption is also reduced.

   Therefore, turbofan engines have been used in large quantities. The disadvantages are large windward area and large resistance, but compared with the increased power, these disadvantages are acceptable.

When he heard Mr. Gu talking about this, Qin Tao suddenly thought of something. He looked at Alexander with a smile: "Dear Mr. Designer, have you ever considered that the front lift engine can be removed and used in the back?" The engine is connected to a transmission shaft, and then drives a fan to provide the power for take-off?"

   During the Yak-38 period, the problem of the flames of the jet engine scorching the deck could not be solved, so the Kiev-class aircraft carrier could only put this aircraft on the shore, and the actual combat capability was greatly reduced. In the Yak-141 period, this problem still exists.

Although the rear **** turns downwards, it will also ablate the deck, but it is turned after all. The most important thing is the front two vertical engines. The nozzles of the two engines are directly aimed at the deck, burning out Deck problems are mainly caused by them.

   Now, Qin Tao offers a solution: replace the lift engine with a fan!

   On the surface, it seems that Qin Tao got the design inspiration from Mr. Gu, but in fact, of course, Qin Tao directly took over the plan of the later generations of fertilizer electricity!

The Yankees will never admit that Feidian has a relationship with the Yak-141, but this vertical take-off and landing scheme is very similar. Of course, if the Yankees chose the X-32 verification machine back then, it would be the same as the Sea Harrier It's in-laws.

  However, Qin Tao, a traveler, has a broad vision and can directly tell the most suitable solution.

In an instant, Alexander's eyes widened. That's right, if a transmission shaft is connected in front of the engine, the power is output to the front, and a fan is installed, then the two lift engines can be prevented from burning the deck. Moreover, The two lift engines are saved, and a lot of fuel can be saved, and the aircraft can obtain a greater range.

  Thinking of this, Alexander's tone trembled: "Qin, your idea is very good!"

   "I still have a lot of ideas, should we talk about it?"

  Alexander nodded: "Everyone, you continue to look at the plane here, and we can look at the engine in a while. Now, I'm sorry." Qin Tao said to the others.

   You have to get rid of the Siamese people, anyway, they are here to see Jacques-141, as for Mr. Gu, they have to accompany the Siamese people, otherwise there will only be those two people left, and it will be easy to get lost.

  So, Qin Tao took Zhao Ling and left, and the old Maozi was with Nicholas and Alexander.

  The four people left the static test room, continued to walk forward, and walked into the tent set up on the tarmac.

  It is already the end of summer, but because Lao Maozi has a relatively high latitude here, there is already a scene of autumn. The entire airport is covered with withered and yellow weeds, and even the runway that has not been hardened can no longer be seen, which is enough to show the loneliness here.

   "This is our Yak-141 test prototype." Alexander said: "We are still looking for the reason, so we can't sell it as junk for the time being."

   "The fault occurred in the control system." Qin Tao said it very directly.

   "Yes, according to the description of the test pilot that day and the live video, it should be a problem with the flight control system. We are looking for it, but we have not found anything." Alexander continued.

"Since it's a software failure, it doesn't make any sense for you to keep this test prototype." Qin Tao said: "What you need to do now is to build another prototype, repeat the actions before the crash, and find the real cause of the accident. The reason is, as long as you sell these rags, we are willing to pay one million rubles. With the money, you can continue to manufacture prototypes."

  Qin Tao came here to buy rags, of course, he couldn’t spend more money, one million rubles for a rag, it’s already a great deal of face.

  Of course, Qin Tao does not have rubles on hand. He only has light industrial products on hand. If he gives the light industrial products to Nikola, Nikola will be responsible for realizing the cash and then paying for it. If they are bundled together, Nikola can also make a fortune.

  So, of course, Nikolai is on Qin Tao's side. Anyway, the Navy is destined not to operate this kind of aircraft. They will have Su-27K carrier-based aircraft in the future.

  In the Soviet era, a planned economy was practiced, and the factory only focused on production, and the coordination of materials did not need to worry about the factory, nor did it need to worry about the products not being sold.

However, in the past few years, they have been carrying out reforms, and the factory has to consider making profits. Especially, if the state does not support the Yak-141 project, then the Yakovlev Design Bureau will have to raise its own funds .

  It costs money for them to purchase parts from their brothers. They need to pay workers to produce prototypes, and they need to burn money for test flights. Where does this money come from?

"Moscow is not optimistic. Although the navy is willing to support the continuation of the Yak-141 project, our economic situation has not been good in recent years. Therefore, after the crash of the Yak-141, many people are not optimistic. This project, it is estimated that I will dismount." Nicholas started assisting from the side.

  More than ten years ago, when Lao Maozi sent troops to the imperial cemetery, he was still so high-spirited, thinking that he was a superpower in the world, but since the 1980s, Lao Maozi has been forced hard.

  The price of oil keeps falling, so that if you sell the oil mined by Lao Maozi, you will lose money, but you can’t make a loss. Once the oil industry stops operating, it will not be easy to restart it in the future.

  They don’t have enough food, so they have to buy food from Western Europe, and even use gold reserves because of insufficient foreign exchange reserves. Of course, the gap between the privileged class and ordinary people in the country is also getting wider and wider.

(It's very strange, Lao Maozi has the black land of Ukraine, how can there be no enough food to eat? Take our current era as an example, Lao Maozi is a proper grain exporter! *** Once there is a war, Western Europe can't get rid of Ermao bought food.)

The economy of the Red Empire is getting worse and worse, so the military industry will also be affected. The children raised by stepmothers like the Yakovlev Design Bureau will have nothing to eat. If you want to continue the project, you must You have to figure it out yourself.

   "However, even if we sell this junk to you, it is not enough for us to build a new prototype!" Alexander said painfully.

  Qin Tao was overjoyed, this guy let go! I like to do business with the leader, and I have direct decision-making power!

   "After all, this is a rag, and it's worth so much money." Qin Tao said: "If you have other rags here, maybe we can give you more."

   Other junk?

  Alexander suddenly became vigilant again: "What do you want?"

   "The design drawings of Jacques-141." Qin Tao said very simply: "Anyway, your project is about to be discontinued, and those waste papers are useless. It's better to sell the rags."

   "No, no, I won't do this, this is simply betraying the Soviet!" Alexander said: "Those drawings don't belong to us, they belong to the Soviet!"

   "But you have been abandoned by the Soviet!" Qin Tao knows that this kind of person has a firm belief in his heart, just like his father, but as long as the other party's belief is broken, it will be easy to cooperate.

   It is not easy for Alexander to sell the design drawings of Yak-141, because this is Alexander's painstaking efforts for many years, starting from Yak-38, step by step to the present, decades of hard work!

  Now, asking him to sell these blueprints is like selling his soul.

  He subconsciously refused, but Qin Tao's words directly entered his heart like a knife.

   That's right, they've been abandoned!

  Since the end of World War II and the death of the Iron Giant, the Yakovlev Design Bureau has been marginalized. Over the years, they have been like children without mothers, unable to eat enough and not to wear warm clothes.

   (Haha, this is a metaphor, they can still eat and drink well.)

  During World War II, half of the planes in the Soviet sky were Jacques, what about now?

   Now what do they have? Only the coaching function can be maintained a little bit, they have become a third-rate design bureau!

"Moscow has given up on you, so you have to show Moscow." Qin Tao continued: "Moscow has dismantled this project, and they don't care about any technology on this plane at all. Their favorite is the Mi Gaoyang Design Bureau, it is estimated that the fourth-generation aircraft is already being made there, right? Back then, your Yakovlev Design Bureau was a hundred times more powerful than Mikoyan Design Bureau. Now, you are going to watch your own Should the project go bankrupt, or should we obtain a batch of funds and rely on our own efforts to make this aircraft a success?"

  Qin Tao's ability to fool people is the strongest, and now Nicholas and Zhao Ling are just spectators.

  Qin Tao's words hit people's hearts directly.

   The belief in Alexander's heart is crumbling. Are you loyal to the Soviet? The Soviets have abandoned you! You have been treated unfairly, shouldn't you make some achievements to slap Moscow in the face?

   "If you give us all the information, those rags are worth two million rubles, so that your funds will be more abundant." Qin Tao said to Alexander: "Think about it, your glory, your dream."

"However, even two million rubles is not enough. If we want to manufacture another prototype, we need at least five million rubles!" Alexander gave up the principle again and again. At this time, there was only one voice in his heart: I need Qian, I want to continue building the prototype, I want to continue to test the flight, I must make the Yak-141 mature, and I must show those people in Moscow!

"Five million rubles? So much?" Qin Tao frowned, and then thought of something: "It seems that we can only go to see what other rags you have, by the way, is there any other rubble in your factory? The same type of engine? The Tucumansky Design Bureau should have built more than one engine of this type, right?"

  Qin Tao said it lightly, but in fact, his heart was beating violently at this time.

  The prototype that has been dropped, as well as those technical documents, are also very important, but for him, the most important thing is the R-79 engine!

  In this era, this engine is very against the sky, as can be explained by a few simple data: the maximum afterburning thrust is about 152 kN, and the unaugmented thrust is 88.2 kN. In this era, the M88, which the French are racking their brains, has an afterburner thrust of only about 80 kN, and the engine on the American F-15 engine has an afterburner thrust of only about 120 kN.

   This product can actually reach the order of 150,000 oxen, and even the domestic turbofan 10 that matured in the 21st century does not have such a power output.

Generally speaking, if a turbofan engine wants to increase thrust, the simple way is to increase the bypass ratio, that is, to increase the diameter of the front fan and blow more airflow backwards. The same core engine is matched with different external ducts. A variety of power outputs can be realized. The engine on the passenger plane that can easily cost two to three hundred kilonewtons is powered by the big fan in front.

  However, this R-79 is an engine with a small bypass ratio. After all, fighter jets cannot have a large bypass ratio. If the windward area is too large, the resistance will be too large, and the speed will not increase.

  In the era when the third uncle of the Su-27 only had more than 120 kN, this kind of engine produced a power output of 152 kN, which was absolutely against the sky.

The design bureau that studied it is actually not very famous. The Tucumansky Design Bureau launched many products in the turbojet era, but it fell behind in the turbofan era. This engine also belongs to the last of the Tucumansky Design Bureau. The swan song.

   This kind of engine is specially equipped for the Yak-141. It is a rare scene for two design bureaus that have been reduced to the edge to hug each other for warmth.

Because this engine is so famous, there were many theories later. For example, the F-35 of the Yankees was said by many bricklayers to use the technology of Yak-141, especially the F-35 above. The -135 engine is also improved from the R-79 engine. I don’t know what the American engine designers will think after hearing this. It is obviously improved from the F-119 engine used on the F-22, but it will be said to be Plagiarized from Lao Maozi.

The Turbofan-15, which was successfully developed by China, was also dubbed a counterfeit engine. The reason was that in the 1990s, it had purchased this engine from the Tukumansky Design Bureau (then it had been renamed the Alliance Aviation Consortium) related information.

The purchase is definitely a purchase, but if it is used directly, it is absolutely impossible, because after the development of the turbofan-15, the performance far exceeds that of the R-79, the thrust has increased by 15%, and the weight is still low. A 20% reduction, this is not a product of an era at all!

But at present, this engine is still awesome. As for the motherland, aero engines are still in the weakest era. Therefore, if there is a chance, it is worth buying an R-79 for two million. .

   As for buying materials, the head of the Tukumansky Design Bureau is not as easy to talk to as Alexander in front of him. After all, the former has not yet reached a dead end. (In later generations, it seems that what we buy is just materials. Of course, the materials are very complete, including how the materials are smelted.)

  Alexander faced a difficult choice.

If he wants to continue to develop the Yak-141, he has to make a prototype. It is impossible for Moscow to allocate funds to him. They can only figure out their own way. If they give the other party what they need, then they can continue. item up.

  However, these are their most precious things, so just hand them over to guests from the East?

  His face was red and white, and his eyes were blurred. He was obviously fighting with heaven and man.

"I don't know if you know that our country is starting to manufacture aircraft carriers. This kind of light aircraft carrier also needs vertical take-off and landing fighter jets. If your Yak-141 can be developed, even if the Soviet navy doesn't use it, we will buy one. If it is approved, we will even deploy it to the island, and the overall purchase quantity in the future will exceed 50, or even reach a scale of 100."

  The last straw that broke the camel's camel was put on it, and the already crumbling faith in Alexander's heart collapsed.

   "Okay, I'm willing to sell you these junk." Alexander said this with difficulty.

  No matter what, even if it is a deal with the devil, he still wants to continue the Yak-141 project!
