AVIC Southwest specially equipped with the turbofan 12 engine for the J-18, that guy planned the maximum thrust of 10 tons at the beginning, but in the end, because of the technical limitations in the eighties, the initial thrust core machine could not fully meet the specified technical indicators. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Therefore, the turbofan 12 engine used in the final delivery of J-18 can only reach just 9 tons of thrust, but there is indeed some progress in the thrust-to-weight ratio, and it has also reached the standard of thrust ratio 8, so the previous turbofan 12 early model is also the first third-generation turbofan engine independently developed and formulated by the Republic, which is of milestone significance.

Also at the beginning of 94 years, the J-18 equipped with the turbofan 12 early model was launched into the air for various flight tests, and the final effect was very satisfactory, and now another year has passed, and it has reached the beginning of 95 years, and the 0112 Institute has also launched the development of the complete version of the turbofan 12 engine.

No way,Who made the speed of the push core machine a little slow after the finalization and improvement of the previous 624 institute,So it was not until the end of 94 years to complete the core machine improvement and finalization work,But it's a good thing to have a core machine,You must know that this time624Institute not only provided 0112 with a complete version of the push core machine,Before a variety of power systems using the push core all carried out performance improvements。

This includes the military turbofan 12, the civilian CG-2000-2 engine project, and the QC-160 gas turbine performance improvement plan at the 420 plant, the whole project is called the QC-160EPE engine, and the slogan shouted there is to directly increase the power to more than 17.5 megawatts.

At that time, it can be regarded as a bad thing for the navy, the reason why the speed of the 052B missile destroyer was only less than 29 knots was because the engine was not strong enough, if the QC-160EPE engine can really reach 17.5 megawatts of power, these four engines can have an extra 6 megawatts of power, maybe the second batch of 052B can increase the speed to 30 knots.

At that time, considering that the aspect ratio of 052B was originally to accommodate two helicopters and the Reif M system, the hull design was even wider than the 052C of the previous plane, so the 052B destroyer of this plane was more seaworthy than the 052C of the previous plane, but the corresponding navigation resistance also came up, and the previous limitation was limited by the problem of insufficient engine power, and the 052B of this plane was even difficult to guarantee 29 knots.

If there is really a QC-160EPE engine, the power system of the 052B should be able to ensure a speed of about 30 knots, and it can be used as a bullish ocean-going destroyer at that time.

All thanks to the newly upgraded design of the thrust core machine, and when the newly upgraded thrust core machine benefits the military turbofan 12, the complete body of the turbofan 12 can reach a maximum thrust of 10 tons, and the engine will be able to push the J-18 to achieve a new thrust-to-weight ratio of the whole machine, with better maneuverability.

Now it is necessary to take out the complete turbofan 12 engine that is planned to be used by the J-18 and install it for the new lightning fighter to be used in an improved version, in fact, it is a matter of effort, anyway, the J-18 is a key project at the national level, and the supporting turbofan 12 engine will promote the development work step by step no matter what, so it is actually a good way to take over the task of upgrading and improving the power system of the lightning now.

Yang Hui is very confident, he knows that after four years, there is an 80% chance that the complete development of the turbofan 12 will be completed, but Northrop and Embraer really do not report much hope, after all, everyone has also seen the performance indicators of the turbofan 10 engine developed by AVIC Southwest before.

If you really want to evaluate the turbofan 10, it is probably the engine of the 60s in the United States, and the finalization time of the turbofan 10 engine is 86 years, and the current 95 is only about 10 years, it is only ten years, and AVIC Southwest said that it can directly chase the international first-class level from the previous 60s to the international first-class level in the 90s, who believes this?

Based on the above facts, it is inevitable that Northrop and Embraer do not trust AVIC Southwest too much, but these distrust will not be too much of a problem, anyway, the current complete version of the turbofan 12 has begun to improve the design in detail, and it is expected that the whole machine will be able to be tested on the ignition bench in the middle and late 96 years, who cares so much about what.

In this way, Yang Hui seemed to be indifferent, and said without any burden: "Now this situation can only be like this, at present, in addition to our United Aero Engine Company, a subsidiary of AVIC Southwest, has the idea to provide such an engine, I really can't see any other medium push engine in the world that can meet the power upgrade needs of lightning, there is no choice!" ”

First of all, the thrust-to-weight ratio is at least more than 9, which limits a lot of things, plus a thrust index of 10 tons, it is really difficult to come up with any finished engine that can be used, unless the three giants of aviation development are willing to develop/improve an engine for the needs of lightning alone.

Guo Yang Hui is not optimistic about who will be willing to develop a large upgrade engine for lightning, the F404 engine has just passed 8 tons of thrust at this time, EJ-200 thrust-to-weight ratio can meet the requirements, but its 9 tons of thrust obviously can not meet the requirements of lightning, other M-88, RM-12, RD-33 engines and the like, not to mention, the only possibility is that Pratt & Whitney can spend money, using technology from F-119, to PW-1120 technical improvements.

But everyone knows that none of the above engines will be specially optimized for the needs of Lightning, after all, the upgrade and improvement of the Lightning fighter at this time is only a preliminary idea, without any orders, who of the Big Three will take this risk?

The engine development unit is unwilling to take the risk of developing such an engine, and the lightning will definitely not have a reliable engine to use, and with PPT to want to successfully bid, the possibility of getting the order is almost zero, so this is a vicious circle.

At present, the only thing that can solve this problem is the turbofan 12 engine, if the turbofan 12 engine can get the lightning power system procurement case, this is not only beneficial to the upgrade and improvement of the design of the lightning, but also the development of the turbofan 12 complete body is also quite good news, which is completely a win-win outcome.

It should also be Yang Hui's words just now that everyone is most unwilling to see the place, and a group of people put their last hope on the side of AVIC Southwest: "Okay, we admit that this is very reasonable, but does AVIC Southwest have a corresponding plan for the middle push engine?" The turbofan 10 engine is too old, it definitely can't work, unless you use the medium thrust core machine you developed for the CG-2000 engine, so maybe it is possible to develop a 10-ton medium thrust turbofan, how do you plan to do it?
