An aero engine with good enough performance is definitely a very big performance improvement for the fighter, at least for now, looking at the four generations of big push in development, its performance is already quite good, and the new fourth generation of heavy combat is only by relying on this turbofan engine with a maximum thrust of up to 17 tons, it is possible to achieve supersonic cruise comparable to F-22. Pen "Fun" Pavilion www.biquge.info

It must be known that when the Americans developed the F-15, the thrust of the F-100 engine developed for it was only less than 11 tons, and it stands to reason that the Su-27 combat combat use of two 11-ton turbofans by the Soviet Union should also be able to ensure the equality of the two aero engines on the two sides.

But why did the thrust of the supporting Al-31F engine reach 12.5 tons when the Su-27 was developed?

This is mainly because the Su-27's physique is half a circle larger than the F-15, and now the F-22 uses the F-119 to launch the thrust of the early version, although it is still less than 17 tons, it seems that the power of the fourth-generation heavy battle supporting engine on the side of the Republic is too much?

However, it is not, the engine of the Su-27 was indeed more fierce than the F-100 used in the early days of the F15, but the physique of the Su-27 was also half a circle larger than the F-15, and now the Republic of China is also half a circle larger than the F-22, so the thrust of the supporting engine must be greater than the F-119 engine of the early F-22, not to mention that after the F-119 was put into service, it was also a few performance improvements. This is just like when the United States upgraded the F-100 manufactured in the early days to the F-100PW-220, in fact, the F-22 in the middle of its life has also undergone technical upgrades.

It's just because of Lockheed . After Martin's F-22 production line was closed, it was impossible for the F-22 to have subsequent production batches off the production line, so when the more than 200 F-22s were upgraded, it was only done secretly with the support of the US Air Force, and there were few official reports.

As long as there is no new batch of aircraft produced, no matter how the old aircraft is upgraded, it is unlikely that there will be a new number to it, the most typical example is the US strategic electronic reconnaissance aircraft RC-135, the combat equipment of this aircraft is mainly electronic equipment, and the electronic equipment follows Moore's law in 18 months of technical performance doubled.

Therefore, the RC-135 reconnaissance aircraft of the United States are all taken to return to the United States every two years to upgrade their electronic equipment, so since the successful development of this aircraft and the equipment of the troops, the technological upgrades experienced in the middle are simply countless, but the Yankees have always only called it RC-135, and there is no A/B/C..... and so on.

After the F-22 was discontinued in the previous place, because there was no new technology-upgraded F-22 fighter produced and put into service, naturally all the F-22 that has been produced and put into service are collectively referred to as F-22, but there is no A/B/C/D technical performance division, but if anyone says that the F-22 has not been upgraded after it has been put into service, it is a real mistake, you must know that after the F-119 engine overhaul time, Pratt & Whitney also upgraded the F-119 according to the F-100 routine of that year.

So in general, it is necessary for the Republic's fourth-generation heavy war engine to set the maximum thrust at 17 tons for various reasons, although this seems to be even more awesome than the F-119 used by the F-22 on the surface, but if you count it in terms of time, you really have reached the time of service, and who knows what level the Yankees have upgraded the F-119 to with the latest technology.

There is nothing wrong with the attitude of being lenient to the enemy and being strict with oneself......

"Chief Engineer Jiang, you are responsible for the development of the core engine of the fourth generation of the 624 Institute, the importance of the task is extremely important, I hope to complete our set goals with quality and quantity, before you were a technician at the 0112 Institute, and then transferred to 624 to take over the mantle of Academician Liu, and now it seems that it is enough to complete the project independently, so the core engine of the United Aero Engine Company will depend on you in the future, and the burden is not small!"

Yang Hui heard the bold words of the fourth-generation push 17-ton thrust before, and it was naturally the head of the fourth-generation push core machine Jiang Hefu, who also accumulated complete experience in the research and development of the core engine through the previous small push core machine, and then improved and adjusted the core engine of the Taihang engine in the northeast of AVIC, and now served as the development of the fourth-generation push core engine, which is the opinion of the 624 Institute. It was also a resolution passed by the top management of the entire United Aero Engine Company.

So now, it seems that the entire core machine project can be carried out smoothly, and this person has also made a lot of contributions and made a lot of contributions.

.......

After having a clearer understanding of the preparations made by the entire AVIC Southwest for the four generations of heavy battles, Yang Hui of course has more expectations for the next year's fourth-generation heavy war bidding, but he doesn't know what plan AVIC Northeast has given for the development of the new fourth-generation heavy battle, which is a mystery that Yang Hui is most looking forward to now.

94 years is Taiwan. The tranquility before the arrival of the sea crisis is also the only period left in the southwest of China Aviation that can be well prepared, but Yang Hui has already known that the crisis is coming, although he did not make fair preparations, but still strengthened the company's fighters, engine production lines to overhaul thoroughly, and strengthen the production of raw materials, upstream subsystem manufacturers of production capacity statistics, management.

It was at this time that Yang Hui was already a little nervous, and AVIC Southwest Company was still moving forward at high speed step by step, for example, the first batch of No. 10 combat aircraft finally walked off the first officially produced and delivered No. 10 fighter with the 15th pulse after the official start of the production line.

It was also under the watchful eyes of the relevant personnel of all parties that a certain unit of the southern Yunnan Air Force, which had accepted the No. 10 train for the first time, happily looked at the newly married "wife", and the deputy division commander in charge of equipment and logistics bluntly said that if he wanted to live in the 132 factory, he would not leave, nor would he have to go home for the New Year or anything, and this time he would wait for the first batch of No. 10 to be off the assembly line and quickly deliver it after the 132 factory completed the test flight.

At the same time, the trial training base has also successfully completed all the flight tests of the No. 10 fighter, compiled a complete set of flight manuals, and at the same time stepped up training and assessment of the pilots of the first batch of troops to receive the troops, so as to ensure that people are equal to equipment, not equipment to others.

Also gratifying is the Artillery Reconnaissance-1 UAV, which has successfully completed the improved test flight, and the newly added battlefield communication relay function has excellent performance, which has been unanimously praised by the army after testing. And the new "Sea Cruiser" long-endurance unmanned reconnaissance aircraft has also quickly completed the design work, the first prototype is also in full swing construction, according to the requirements of the schedule, this time it may even be at the end of the year for the first flight, after all, who called the UAV The design is relatively simple, and the test flight cycle is also short.

And exciting, is the first Z-18 helicopter to complete the prototype manufacturing, through two years of the Z-8 helicopter almost pushed to the restart of the design, the new Z-18 helicopter not only height has been significantly controlled, weight loss work, the appearance is more sci-fi, cool.
