The fourth-generation heavy battle plan of the 0111 Institute is matched with the new generation avionics system brought by Li Yun, at least so that the heavy four solutions will not lose to F22 in avionics. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

As for the aerodynamic shape, in terms of the aerodynamic design alone, I am afraid that in terms of maneuverability, it is on par with the F22. Although it is the same conventional aerodynamic layout design, the design of the 0111 Institute has more full-motion camber tail, and the increase in maneuverability brought by this technology must also be acknowledged.

But in fact, the thrust-to-weight ratio of the whole machine of F22 must be better than the heavy four scheme of the 0111 Institute, and it is even possible to directly win the three design schemes of the Republic participating in the bidding this time.

This gap comes from the gap between the Republic's understanding of the heavy aircraft physique and the American standard, as far as the overall physique of the F22 is concerned, it is probably the same as the positioning of the F15 in the United States back then, with the smaller body of the heavy aircraft in exchange for a larger thrust-to-weight ratio of the whole aircraft.

That is also based on the indicators of the republic, the heavy aircraft must be a big guy like the Su-27 to be tasteful, even if the engine used in the domestic heavy four can reach the same level as the F119 engine, it must be behind the F22 in terms of the overall thrust-to-weight ratio, which must be admitted.

In this way, the advantage brought by the full-motion vertical tail before, and because the thrust weight of the whole machine is backward above, it can barely offset their respective advantages in terms of maneuverability, and it is roughly able to fight a tie!

In terms of other stealth designs, this Yang Hui doesn't think that the 0111 Institute's plan will lag behind F22, and even the backward stealth ability will not be weak.

As far as stealth is concerned, I am afraid that the other two design units in China have come up with plans that cannot be compared, so in general, it should be possible to call the plan of the 0111 Institute as the entire heavy four bidding, focusing on the design scheme that pays the most attention to stealth performance.

Yang Hui is not clear about the army's requirements for the heavy four this time, whether it attaches importance to stealth or mobility, or requires low risk, super long range, etc., so there is no way to give some key optimization directions for the 0111 plan.

Anyway, everything can only be said to be, everyone still does the best design according to their own ideas, and as for which plan the army will choose in the end, it really doesn't matter.

…………

When he left the 0111 Institute again, Yang Hui also rushed to the 611 Institute for investigation and investigation, or to inform the army of the latest project progress requirements, anyway, to put it bluntly, this is to take a look at the 611 Institute.

When it comes to the research conducted by the 611 Institute, Yang Hui must have arranged this action at the end of the research trip in Jinguancheng, after all, the 611 side is the finale project.

According to the arrangement, this time the first thing is to go to the 420 factory for research, and this time the difference is that the 420 factory is no longer concerned about the QC160 gas turbine project, nor is it concerned about the QC280.

On the contrary, the AL31F engine overhaul line, which had not been taken seriously before, was only used as a replacement engine project before Taihang entered service at the beginning, and this overhaul line was not too eye-catching at that time.

And now it is different, the Air Force will soon purchase the 10th in large quantities as the main combat equipment, which means that at least the 31FN engine needs to be overhauled.

Coupled with the Su-27 fighter jets purchased in China before, the 31F engine used in this aircraft is more ruthless, and it is directly about to go to the first overhaul point, and the first batch of engines ready for overhaul has begun to be handed over from the army to the 420 factory.

In addition, this time the Air Force is obviously very satisfied with the Su-27, which is why the technology of introducing the Su-27 fighter is ready for domestic production.

For the localized Su-27 fighter project, although many subsystems require localized substitution, only the engine will continue to rely on 31F for the time being, and there is no way to do this.

Correspondingly, this also causes the domestic J-11 to also use the 31F engine, so it seems that the domestic 31F series engine is definitely the main military push for a long time.

This is just a 31F engine overhaul line, which is enough to ensure the continuation of the main business development of the 420 factory, not to mention that the 420 factory at this time under the auspices of Xiang Qiao, the technical improvement of the 31F engine has achieved initial results.

When I walked to the scientific research and technical office of the 31F engine overhaul line project, I obviously saw a group of Maozi bargaining with the 420 factory, and it seemed that the 420 factory still had the upper hand.

This is very interesting, what is Maozi going to do here? It was to quietly walk to the side, find a seat and sit down, and concentrate on being a listener.

………

"No, no, we want the full production capacity of this technology, not to purchase your finished parts, this is something that must be clear, think about the distance between our two factories, we really can't accept it in terms of transportation costs alone, so please think again."

It is normal for the Republic to introduce foreign technology, but after the introduction of foreign technology, the introduction of technology can be quickly optimized, improved, 420 factory 31F engine overhaul line project is absolutely the benchmark.

Of course, in fact, it is not impossible to say that after the introduction of this kind of technology in the Republic, it is not nothing, as long as you are willing to look for it, you will definitely be able to find it.

The problem is that the improved and developed technology like the 420 factory can be highly valued by the original factory, and the technology can be re-sold, which is absolutely rare.

It's a pity that in the face of this requirement, the 420 factory that has the initiative is not moved at all, and they are deeply aware that they are now looking all over the world to achieve the technology of extending the life of the 31F engine at a lower cost, and there is only one 420 factory, and there is no other semicolon.

"No, we have always insisted on only selling finished products, as for the issue of freight, I think this has never been a problem, using the mode of train transportation, the freight is actually very low, and even our 420 factory can afford home delivery."

Compared with the profitability of exporting such high-end finished parts, freight is actually insignificant, which is not a big deal, and we have to bear this burden.

Maozi is facing this kind of oil and salt does not enter the master, but also completely helpless, Nima when we exported the overhaul line, did not have such a score, you can not miss the old feelings in the 420 factory now, we are all old friends.

"It's not good for your factory to do this, when we exported the 31F engine overhaul line, we were heart-wrenching to you, and now you are doing this, that is to ignore the traditional friendship between our two sides, so that our future cooperation may be .........."

"And I heard that you are preparing for the localization of Su-27 fighters, and it is inevitable that you will have to purchase a large number of 31F engines at that time, and we do not want to cause a temporary shutdown of 31F engines because of your factory."

Rub, this is soft is not good, are you going to prepare to come hard? It seems that Maozi is completely impatient, but after this kind of impatience, he wants to use the export order of the 31F engine as a bargaining chip, which is probably not a good idea. (To be continued.) )
