"There is the final stage of the aircraft factory test, then we don't need to see too much now, according to the planned itinerary, we still go to see the development site of the turbofan 12B engine, the power system development work over there is related to the power upgrade plan of the entire JF-18 series of fighters can be successfully implemented, so in the current situation, we are still promoting the research and development work in accordance with the scheduled schedule. Pen "Fun" Pavilion www.biquge.info"

Hurry up and prepare to get on the car, now responsible for the development of the turbofan 12b engine 0112 and the production and trial production of the Liyang factory are not in the Guiyang Aviation Industrial Zone, must drive again dozens of kilometers away Pingba County, where is the United Aviation Engine Company military engine project research and manufacturing base.

At this time, AVIC Southwest is no longer the AVIC Southwest ten years ago, and the supporting equipment and facilities that should be there should be all added anyway, including the transportation used to receive important people and visit the delegation.

"To the location of the supplier of the JF-18 fighter power system, we need to take about half an hour by car, and now I will tell you a complete set of design improvement plans about the JF-18 series fighter power system, which can also be used as a reference for everyone."

For the JF-18 is currently facing a dilemma, the power system is definitely a problem that must be solved for the customer, especially when the UAE military fighter will not maintain the scale of hundreds or thousands, and the fighter is required to perform better and be more reliable.

Therefore, all kinds of contradictions and problems have come out, just as the UAE previously asked AVIC West to provide the response time of the Persian Gulf surveillance/fast reaction system from 20 minutes to less than single digits, for the mid-to-late performance upgrade plan of military fighters, this is also a very optimistic point.

The last United Arab Emirates spent more than a billion dollars in 98 to upgrade the old Mirage 2000 fighter, the reason is because Dassault has a special technical service support, and compared with the current JF-18 fighter, I am afraid that this aspect of the performance improvement plan is more needed.

To this end, Yang Hui is now preparing a complete set of JF-18A/B fighter mid-to-late power train upgrade plan for the UAE, which will have a very big impact on whether the UAE will choose JF-18 in the end.

"At present, the power system that we can provide to the JF-18 in a short period of time can only be the turbofan 12A engine, and this engine has been finalized for almost two years, and the performance in all aspects is quite good, except for insufficient thrust, there are no other significant shortcomings, so now it is also a good engine. So for the turbofan 12b, we expect to wait until about 99 years to complete the finalization of the engine and the adaptation of the aircraft, and wait for the follow-up use of one to two years if there is no problem, it can be considered completely mature, at that time we expect it to be six years later. ”

There is no way to do this, just the engine development and shaping is certainly not enough, the follow-up must do a variety of adaptation work with the aircraft, after the completion of the adaptation work, there will be a period of trial, such a whole set of processes have been experienced, the engine can be regarded as completely mature, and only such an engine is likely to be favored by foreign customers.

For Yang Hui's statement, the oil tyrant has heard it once, and he probably has the bottom in his heart before, so he doesn't have any excited thoughts anymore, and now they are most worried about the follow-up upgrade of the fighter just mentioned.

"I know this problem, and now we want to find out a situation, that is, about the development of the turbofan 12B engine, can I purchase our current JF-18A/B fighter jet, and ensure that after the new engine is successfully developed, we will upgrade and improve our fighter in the first time?"

There's no way, the oil bully is like this, it's really normal to say that the oil bully is anxious, if the oil bully is not anxious, it would be a really strange thing, after all, no one wants to see a fighter that obviously has the potential for air combat, dog fighting, and strong air self-defense capabilities because of the lack of power, but it can only be used as an attack aircraft.

Therefore, Yang Hui gave a more formal statement: "As for when the turbofan 12B will be provided to the JF-18A/B fighter in the form of a power upgrade package, we expect that it will take about six years, and then we will be able to upgrade the power system of all JF-18 fighters using the turbofan 12A engine." However, at that time, the UAE may have encountered a problem, mainly considering that the life of the turbofan 12 series engine has a very good performance, under normal use, we expect that by about 2000, there will be at least two-thirds of the remaining service life, if this time directly replace the engine, it will be a great waste. ”

The cost of military turbofan engines has never been cheap, and now the factory cost of a turbofan 12a engine of United Aero Engine Company is 3 million US dollars, and when the price of the turbofan 12B engine installed on the Lightning 2 was discussed with the Brazilian side, the United Aero Engine Company has set the price of a single engine to 5.5 million US dollars, and the current turbofan 12A performance is not as good as that of the turbofan 12B, but the external price of the engine is still as high as 5 million US dollars.

At this time, the UAE's order plan is 60 fighters, which means that the engine will cost 600 million US dollars, and if the UAE replaces the engine after only one-third of its life, it means that there will be at least 300 million US dollars in losses, which is still considerable. (Note: For an engine to use all its life, it is necessary to consider not only the initial purchase amount, but also the subsequent overhaul costs.) ）

Therefore, out of the foothold of conscientious sellers, Yang Hui still feels that it is necessary to tell the UAE about the waste of the life of the turbofan 12A engine, which involves the vital interests of buyers, although 300 million US dollars is not much for tens of billions of dollars in project orders, but this is enough to do a lot of things, such as the purchase of MPC-75 business jets can buy four.

"It's a bit tricky to think of wasted engine life, so do you have any other good ideas to recommend?"

I know that this problem will be pushed to AVIC Southwest in the end, and let AVIC Southwest give the best solution to the problem by itself, which can be regarded as a variety of worries and consultations that buyers should have before finalizing the order, so when Yang Hui should answer, it is still the same.

"There are two ways to solve the problem, as for which one is more suitable for the UAE, this question depends on your own choice, but it is definitely much better than directly replacing the engine and scrapping the old engine, this is what we can guarantee." (To be continued.) )
