After all, CG-2000 is a civilian engine to be sold, and all kinds of news about this engine must have been inquired about by the major giants.

Then it is reasonable for Nuoge to think of the core aircraft of the push, especially the semi-public military fighter such as the J-18 in the southwest of AVIC, and constantly brush the sense of existence, if you really reason a little, you will be able to know that there is definitely such a high-performance thrust turbofan engine project in the republic, but for various reasons, United Aero Engine Company did not choose to announce it at the first time when the engine was finalized. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

There is no announcement, but this does not mean that the turbofan 12 cannot be announced to the public, at least at the beginning of the development of the J-18 aircraft, AVIC Southwest had an agreement with the domestic army, requiring the export of J-18 fighters, which has led to the fundamental reason why the J-18 has always been semi-open to the outside world.

Since the whole machine can be exported, there is naturally no reason to keep the supporting engine too secret, and now if you want to export the engine, it can almost be made public.

"That's right, it's the CG-2000 engine used on the core of the thrust, we have developed a military thrust turbofan engine on the basis of this core machine, but the thrust-to-weight ratio and thrust are not ideal, and now we are planning to start the turbofan 12B engine program, and the required performance indicators are just similar to the new engine indicators required by the lightning."

This time, because there is no order for the upgraded version of the Lightning, and there is no order, it is naturally difficult to have relevant funds in place, and support the development of the turbofan 12b, but this is not in the way, with the early version of the turbofan 12 that has been finalized as the foundation, the scientific research funds required to improve the upgraded turbofan 12b are not too much, even if there is no external capital injection, the development work can be smoothly promoted.

In this case, Yang Hui only needs to try to win the turbofan 12b installation export opportunity, as for whether this will be cheaper lightning here, this Yang Hui is more open, although there is no need for lightning here to invest too much money in the development of the engine, but when the lightning needs to purchase the turbofan 12b engine in the later stage, AVIC Southwest has a reason to make the purchase price of the engine higher.

In order to earn more in the future, and in order not to bring too much financial pressure to the upgrading and improvement of lightning now, Yang Hui does not plan to ask for money now, which seems too vulgar and utilitarian, Yang Hui feels that even the early consultation and technical service fees can be waived.

Given such a strong news, Northrop and Embraer here are also open-minded, looking at the meaning of this turbofan 12b engine, it should be a more reliable engine, plus the engine has completed the finalization of the initial model, and the probability of success of the follow-up improvement and upgrade plan is definitely not small.

Didn't wait for Northrop to react, Embraer staff first began to gear up: "We are still very willing to believe in the technical capabilities of AVIC Southwest Company, then the lightning upgrade and improvement of the power system will be handed over to AVIC Southwest, the success or failure of this new engine is related to whether the lightning can still maintain competitiveness in the international market after 2000, and I hope that General Manager Yang must pay attention to the development of this engine!" ”

Embraer is concerned about it, even if there is no lightning demand for turbofan 12b this time, the entire turbofan 12b project will not be affected in any way to move forward with the development work, and even now there is a lightning demand for turbofan 12b here.

In fact, it is difficult to say whether United Aero Engine will continue to invest more resources in the turbofan 12b, after all, it has been able to extract as many resources as possible before, and now it is impossible to extract the resources of the fourth generation to tilt the turbofan 12b, right?

Although I know that the situation is the same thing, I must brag hard when answering Embraer at this time: "Please rest assured, now the turbofan 12b project not only has the domestic demand of our Republic, but also has a lot of international demand, and after I go back, I will ask the relevant units to allocate more resources, and we will be able to complete the design and manufacturing work according to the schedule." ”

Since it is the first choice to upgrade the power system of the lightning fighter, at least there is a very good optimization in the fuel consumption of the engine, the intermediate thrust fuel consumption has been reduced from 0.78 to 0.75 of the PW-1120, not to mention the reduction in the empty weight of the whole aircraft after the weight reduction of the engine, compared with the 1.3 tons of the PW-1120 and the 1.1 tons of weight in the turbofan 12B plan, the weight of 200kg is simply a blessing for a fighter.

........

But the upgrade and optimization of a fighter is definitely not only the engine is good, since the aircraft is to face the international market after 2000, if you still take the international 80s machine sweep radar to pretend to be abused, so the choice of radar followed by the power system is also particularly important.

To choose radar, Yang Hui said that this is no problem at all, the same is the only radar supplier for lightning Changhong company, people have now begun to tackle the active phased array radar technology, now as long as the lightning improvement design has this idea, I believe that Changhong factory will definitely be able to provide an active phased array radar for the local tyrants to play.

However, in Yang Hui's personal opinion, I am afraid that there are very few sellers who are willing to equip the lightning with active phased array radar, so it is better to design it simply, and upgrade the technology of the flat slot machine scanning radar used on the lightning before, and slightly increase the detection range of some radars, and integrate the data into the preliminary network data link for radar electronic data exchange between fighters.

Continue to talk eloquently: "To upgrade and improve the Lightning fighter, I think this original radar also needs to be optimized and improved, it must at least reach the same level as the radar of the JAS-39 fighter, and this only needs to use the new technology of recent years to upgrade the existing radar of the Lightning in a small range." ”

It is actually possible to upgrade the technology on the basis of an old radar with excellent performance so that it can adapt to the combat environment in ten years, for example, the radar used by the famous Typhoon fighter is not a new development, but is upgraded and improved from the old radar.

It is necessary to upgrade the performance of the lightning fighter, but as a fighter that is positioned at a high cost performance from the beginning, through the upgrading and improvement of the old radar to achieve performance upgrade and optimization, as long as it can keep up with the mainstream level of the times, it will not lag behind, so that the cost of radar will not rise sharply.

In addition, because the PW-1120 used before was an American product, although the performance was considered a mainstream product in the eighties, the price was very low, but this time the turbofan 12B was replaced, Yang Hui did not think that the price of the engine would be lower than the PW-1120.

Of course, if you want to say that the cost of turbofan 12B is high, it may not be too high, at most, it is just to add some inflationary price difference on the basis of the original PW-1120.

Generally speaking, in the lightning upgrade and improvement plan, the most critical power system and radar will not have much price increase, but the performance improvement brought is real, which will ensure that the lightning will still be able to ride the dust with better cost-effective data when it meets the European three musketeers head-on in the future.
