"Radar issues, let's not talk about it, here are some of our technical details of the J-8II, which is the overall aerodynamic layout concept. You can start by looking at the fact that we have to come to an agreement before we can sign a contract with the Iranians. After all, the fighter jets provided to them will be described in detailed technical details on the contract...... "Liu Yijiu did not hide that it was to be exported to Iran."

For five days, he ate, drank, and slept in the technical design room of the 611 Institute.

The results have been encouraging.

Although, at first he did not want the republic to be equipped with this in large quantities.

However, the Republic and the United States are in the Peace Model 82 Project, 50 sets of airborne radar and fire control systems and 5 sets of backups, with a total value of $550 million. The radar is only the AN/APG-66 radar that Westinghouse is equipped with F-16 fighters.

In the end, this kind of radar was not able to be used on Chinese military aircraft, because of the shamelessness of the Americans, and the wishful thinking of Chinese officials in international negotiations, forgetting the huge risks.

"This ......" Seeing the new pneumatic layout, Gu Yifen was immediately shocked.

The original aerodynamic layout of the J-8 fighter adopted a delta wing layout, and the new aerodynamic layout provided by Liu Yijiu actually added a canard wing layout in front!

Even the rear wing has been changed.

The rear rear wing has been changed from a single tail to a double tail wing!

It's no longer the appearance of J-8 at all.

In other words, Liu Yijiu's request was for Shen Fei to come up with a brand-new fighter within a year. It's simply not possible!

It is not possible to even do a ground static pressure test, and directly produce a prototype for test flight without a blowing tunnel. It's absolutely not a no-go. Strength structure test. Pneumatic layout, etc., all require a lot of testing tests.

"Director Liu, this is simply impossible! For heavy fighters. No one in our country has experience. Although the canard layout can provide greater lift, allow the fighter to take off at a shorter distance, and make it more maneuverable, at the same time, the dual tail layout can also effectively improve maneuverability, you are also very familiar with it, and you should know the difficulty of implementation. We have not yet started research in this area in our country. Otherwise, the J-8 would not have progressed slowly all the time...... "This aerodynamic layout is good.

But for the Chinese aviation industry, this aerodynamic layout is unfamiliar.

Although it is very desirable to study this startup layout. Gu Yifen felt that Liu Yijiu was simply fooling around.

Just this drawing made Liu Yijiu's impression very bad.

It's too unrealistic, and this kind of thing is simply unrealistic for China at present.

"I know it's unrealistic. This is not the aerodynamic layout of the J-8II, but our new generation of fighters. It integrates the aerodynamic layout of the Meidi F14, or it is more suitable to imitate the F14......" Liu Yijiu shrugged his shoulders and said indifferently.

"......" everyone was speechless.

"Alright, here's it. The next step in our 611 research program is the maneuverability of the F14, which the whole world knows because of this aerodynamic layout. For China. This kind of is indeed very difficult. So, it is necessary to wait until the Iranians give us the F14 in their hands. will expand. When the time comes, I hope that the 601 Institute will be able to cooperate with us in this regard. Liu Yijiu set his sights on the people of the 601 Institute.

Otherwise, he wouldn't have taken out this pneumatic layout.

As long as 601 is moved. He had a way to get people to 611 and didn't want to go back.

At the end of the day, I didn't take back the huge drawing. Although he painted it for more than ten hours.

Signaling to Li Rui beside him, Li Rui directly instructed the two designers of the 611 Institute to bring in a blackboard. It was covered with a red cloth.

After it was opened, a three-shot view of a single-shot light fighter appeared.

Compared with the J-8 and Shenfei's J-8II, the aerodynamic layout has also been greatly improved, and the most important thing is to add a canard wing design in front of the main wing of the aircraft. This makes this light aircraft a little weird.

The original air intake has also become rectangular.

"That's fine, right? I haven't seen your blueprints, but here are some of the improvements we've made after discussing them. The design of the front canard wing is to allow the aircraft to rise into the air faster, and at the same time improve the stability of supersonic flight, reduce the load of the main wing, and effectively improve maneuverability......" Zhu Houdao seemed to have guessed the reaction of Shen Fei's technicians early on.

Holding a teaching stick and pointing to the design pattern on the blackboard for a detailed explanation.

Gu Yifen, Zhao Yutong and others smiled bitterly, no wonder Liu Yijiu wanted to throw out a new aerodynamic layout of a heavy fighter to show them first, probably because he was worried that they would reject this strange design.

"In addition, there have been improvements in the direction of the nose, which is due to the requirements of the new fire control radar. This point needs to be introduced by Comrade Huang Qingyu, who studies radar. Zhu Houdao did not occupy the podium, but handed over the teaching stick in his hand to Huang Qingyu.

Huang Qingyu did not have a good impression of this kind of radar, and what he hoped was to be able to install an active phased array radar on the aircraft.

Current phased array radars have suffered from miniaturization, but this is not incomprehensible. If it weren't for Liu Yijiu's request, he wouldn't have wasted time running out to introduce this kind of radar, which would not be eliminated in a long time.

Although, it is somewhat wasteful to have an active phased array radar on top of a light fighter.

He didn't explain anything about the drawings of the fighter, but also asked people to bring in a blackboard and put it on the side, pointing to the drawings on it and introducing it weakly: "This thing is the diagram of pulse Doppler radar components, which is divided into 7 replaceable parts, antenna, transmitter, receiver, digital signal processor, computer and control system. Pulse Doppler and single pulse systems are used. THE WORKING BAND IS IN I/J, THE FREQUENCY IS 6-10GHZ, THE VOLUME IS 0.11 CUBIC METERS, THE WEIGHT IS 110 KG, THE MTFF100 HOURS, AND THE ANTENNA DIAMETER IS 700CM. Plane search distance: RCS=5 is 75 km, scanning range +/- 60 degrees. Working states include: Empty, Up, Down, Dogfight, and Automatic. Vacant ground includes: air-to-ground ranging. Functions such as vacuum velocity mapping, Doppler beam sharpening, map freezing, and auxiliary navigation and sea search, including ......"

"The new fire control system requires a modification of the cockpit as well. Not only is there a head-up display, but also a multi-function display is added. The main function of the multi-function display is used for computer integrated navigation, such as Doppler-inertial, in-flight alignment, ground positioning system-inertia, etc.) and auxiliary tasks such as maneuvering, fire control, and fuel management...... Backup is the attitude and heading reference system......"

Huang Qingyu introduced weakly, but the pens in the hands of several technicians from Shen Fei never stopped.

Liu Yijiu only rolled his eyes when he heard this.

This old thing, it's just too much to take the task seriously.

"Therefore, there needs to be a relatively large improvement in the front of the nose, otherwise this thing will not be installed." Following Huang Qingyu's words, Liu Yijiu stood up, "Although there is a relatively large improvement. But at the moment, our high-altitude and high-speed fighters need the avionics systems of the Americans, so we need to complete all the improvement work within a year, and test flights to test the rationality of this design. ”

Liu Yijiu's words made the director and secretary of Shen Fei, who did not understand technology, in a fog.

From the beginning of the kindness, they were dizzy.

Huang Qingyu was as weak as reading the explanation of the textbook, which made them even more in the clouds.

And the technicians. looked at Liu Yijiu with a frightened face.

The completion of the test flight does not mean that it will be able to enter the battlefield, Liu Yijiu is to let the Iranian air force pilots help China test the performance of this aircraft on the battlefield!

"Director Liu, this can't be done in a year. The good way should be clear. How much time does it take! And, within a year, even if we were able to complete the design renovation work. And the production of prototypes, it is impossible for such fighters to be put directly into real combat! ”

For Liu Yijiu's very lax approach. Gu Yifen couldn't stand it anymore.

Even for the sake of 140 million research funds, he felt that he couldn't accompany Liu Yijiu to mess around like this. It's going to kill you.

Scientific work should be serious. In the work of science and technology for national defense, we must be more cautious and careful, and it is most important to be safe.

"Really, can't? Your design refinement work is basically complete, and the aerodynamic layout has been improved, and we can complete the interior layout design while producing the prototype blowing tunnel. In addition, the engine is a turbofan-6G, or continue to use a single turbojet-13A twin-rotor engine with a thrust of 6,600 kg, after all, you have already completed the first flight......"

Liu Yijiu really has no interest in the backward turbojet rotary engine.

The historical mission of the Eighth Master will exist for a long time, even if they make an advanced fighter, or they can achieve imitation of the F14 within five years, it is impossible for the Republic to configure it on a large scale.

For the older generation, if the US imperialists had not experienced the Gulf War, they would still feel that the number of fighters could make up for the gap in technological performance to a certain extent.

The air force of the Republic really learned from the pain after the Gulf War Americans showed the war mode of the new era.

And most importantly, the republic is short of money.

Huge airspace defense requires a large number of fighters.

No matter how advanced the fighters are, if the number is small, they will be besieged and killed by enemy aircraft.

The leaders are well aware of the country's technical strength and equipment level, unless Liu Yijiu can quickly make a cross-generation stealth fighter such as the US imperialist F22. Even so, more fighters are needed to cooperate with the operation.

Just as the Republic has J-10 and J-20, there are still a large number of seventh and eighth masters in service.

That's the 21st century! Although the seventh master has undergone countless facelift surgeries, he still looks young, although the eighth master has undergone countless blood exchanges, and is infinitely close to the third-generation fighter. However, it is still a second-generation fighter.

"If you don't change the engine, the aerodynamic layout doesn't go through much modification, the problem won't be too big!" Seeing that the chief designer was already on the verge of breaking out, Zhao Yutong hurriedly pulled Gu Yifen and said to Liu Yijiu.

What he feared was that the two had fallen out.

Once it falls out, the 140 million funds will fly.

"Indeed, Director Liu, if you don't do that, let's try it first? When the time comes, let the comrades of 611 also participate in it, and everyone will discuss it together. Obviously, Ma Jijun has already regarded the 140 million as Shen Fei's money.

It really can't be done, so they will produce a few according to Liu Yijiu's requirements, seven million dollars each, even if their fire control radar needs one million dollars, the cost price will not exceed too much. However, if you change to a turbofan engine, then the price will definitely not work.

At least there must be a profit of almost three million dollars, 12 million dollars, two years of scientific research funding, and it would be a fool not to do it.

Moreover, the minimum number is four, and the Iranians will not be so stupid to exchange 80 million planes for two planes with a total value of just over 10 million dollars. Therefore, the number will definitely be more, and the money they pay will be more.

"If there are no problems, people can discuss the details of the interior layout. Needless to say, the pneumatic layout. The main ones are radar, as well as fire control systems. If you plan to use the turbofan-6G, then our turbofan team is in the research institute, and you can discuss it with Qi Hai and Wu Yuankong. Within three days, I want results. The negotiations between me and the Iranians can drag on for four days at most! There is a war going on in their country, and it is impossible for the Minister of Defense to stay here for too long! Liu Yijiu didn't care whether these bigwigs agreed or not, and said very strongly.

It is simply impossible to get them to listen to themselves when they have not tasted the sweetness at first.

Moreover, he is a young man, and before he worked as a designer for thirty years, he was not worth mentioning at all.

Standing on the shoulders of giants, it is not so easy.

After all, the giant was too tall and the wind above it was too strong, and he fell off without paying attention.

"What the hell! It's great to be rich! Seeing Liu Yijiu's resolute departure, Gu Yifen suddenly broke out.

Liu Yijiu didn't hear it at all.

"Old Gu, don't scold here. Either accept it, or we'll make this ......," Zhu Houdao said with a wry smile.

Although Liu Yijiu is young, he seems to surpass them in all aspects of technology.

Casual suggestions can often reduce a lot of detours.

"What is this not nonsense? Changes to the aerodynamic layout, this is child's play? Although the changes are not big, it involves the overall structural strength and many things...... "Gu Yifen also felt that she was a little excessive.

But what Liu Yijiu did was too much.

"There's no way around it. He wanted to get the F14 from the Americans a few years ago, Iran sent it to the door, and he will let it go? Not to mention anything else, this kind of improved fighter must be worth at least tens of millions of dollars in his hands, so four is just the price of his landing bargain, and it is likely that it will eventually be doubled. Nearly 300 million funds, can Shen Fei refuse? Huang Qiaosong's words silenced Shen Fei's people. (To be continued......)
