Yang Hui, who is far away in the southwest corner of the Republic, is still having a headache for various problems, in order to find a way to get the axial symmetry vector nozzle technology from Russia, it is also thinking of a lot of ways, and there are also people in the middle of the research on the stealth performance of the sawtooth tail nozzle, although the final result has not been able to be obtained in a short period of time, but Yang Hui himself is absolutely aware of it.

Of course, we have also received a message from Brazil, Thailand and Egypt, demanding that when designing the shipborne version of the Lightning, the use of cumbersome side panels should be abandoned, and the use of digital fly-by-wire flight control should be used instead, and the shipborne version of the lightning combat should be made the best of all lightning fighters, and even the three countries are considering whether it is possible to replace the shipborne lightning with a more powerful mid-thrust engine.

But fortunately, at this time, the shipborne version of the Lightning had just completed the most important design of the nose gear and tail hook, and was not ready to start building a prototype, so everything still had time to be improved accordingly

And far away in Europe at the Farnborough Airshow, on the first Sunday of September.

AVIC Southwest's Xifei Company exhibited the MPC-75 passenger aircraft together with Germany's MBB, striving for further gains; United Aero Engines and MTU pulled out the CG-2000 engines for the exhibition, but not many aircraft that needed 7.5 tons of engines were used, and even the MS-4 engines were pulled out for a walk under the guise of a joint venture between United Aero Engines and the Brazilian government.

As for the Lightning, which has just won a large purchase order for 150 new aircraft in Egypt, it is even more highly praised by Northrop and Embraer, and the reason why Embraer does this is easy to say, after all, this guy has never produced fighter jets, and now he has the opportunity to seize it.

And Northrop is because through this Egyptian order, they saw their opportunity on the lightning fighter, now Northrop not only does not have the F-20 fighter project, lost to Lockheed on the fourth-generation aircraft, and even the B-2 bomber, which has always had high hopes, was cut by Congress because of the collapse of the Soviet Union, and the final number of remaining orders is only a fraction of the original planned order, which shows that Northrop is now suffering heavy losses.

It can be said that Northrop's domestic project in the United States is really a comprehensive rout, in order to ensure the survival of the company, for example, the lightning fighter that has just won an order of 150 is simply a lifesaver, just in Egypt This project, Northrop is expected to have a profit of 360 million US dollars, if it can be more deeply involved in the lightning project in the future, I believe there can be more possibilities.

So, Northrop has become a lightning salesman who spares no effort in this air show, those countries that were originally equipped with F-5 fighters, Northrop has detailed information, and now when you meet one at the air show, you will sell one, if you can't meet it, then wait until the end of the air show to sell it, after all, according to the plan discussed before, even if you only sell out the most basic entry-level side plate lightning, Northrop can also get 20 percent of the profits during the entire life of the fighter.

With such a stimulus package there, don't you really say that just at the air show, Northrop has pulled a country that is interested in purchasing Lightning: Greece, a country that is equipped with up to three digits of F-5 fighter jets in large quantities, and most of the F-5 fighters in their hands are about to reach the end of their life, and the same cheap and easy-to-use Lightning fighters have also entered the scope of consideration.

Xie Lianfa, who accompanied the exhibitor, was even more stunned when he heard the news, if Lightning can seize the opportunity to serve in Greece, then it must be great news, at least Greece is also a European country!

Xie Lianfa, who didn't speak for the time being, sat aside and listened, but Greece was obviously still a little dissatisfied with the current lightning: "Since this fighter won Egypt's order, we have noticed it, although Egypt's choice of fly-by-wire flight control version of the lightning fighter must have greatly improved in performance, but this is not enough, the performance of the so-called turbofan 10 engine is too poor, we don't need it, if we can replace it with an engine with good enough performance, we can think about it." ”

In these years, the customer is God, not afraid of Greece's request, afraid that he does not make a request, as long as the request is made, there will naturally be a plan that can meet the requirements, and now Northrop has a way to meet Greece's requirements, anyway, this fighter is also produced in Brazil, the so-called embargo on the republic will not work, and when the time comes, coupled with Northrop's influence, there will be great hope for winning the Egyptian order.

In the blink of an eye, there was a rough plan: "There is no problem, isn't it still a little dissatisfied with the power!" Since I am not satisfied with the 7.2 tons of thrust of the turbofan 10, I don't think I need to sell the F-404 engine, but the RM-12 engine is not bad, just reaching 8 tons of thrust, but considering that the lightning and the Swedish JAS-39 fighter have a great market conflict, so we don't choose it, and in the end there are only RB-199, PW-1120, M-88, EJ-200 four suitable engines, you can all consider it. ”

Not to mention, after having Northrop as the backstage, the advanced engines of Western countries are all open to choice, which makes Xie Lianfa even more envious after seeing it on the side, although I also thought about recommending the turbofan 12 engine in research and development just now, but after thinking about it, I still chose to give up, although the turbofan 12 performance can meet the comprehensive performance requirements, but Greece will definitely not consider it.

Obviously, the eyes of the Greeks were also poisonous, and they ruled out two unreliable engines at the first time: "The thrust of just eight tons of RB-199 is not enough, forget about this; The thrust of the M-88 engine doesn't seem to work, and looking at the published data, it seems that the fuel consumption is very high, so there is no need to think about it, the remaining PW-1120 and EJ-200 engines are okay, so do you think that from a technical point of view, which one is more suitable? ”

Good guys, this Greece directly chose two engines with a thrust of more than 9 tons, and such an engine pushes the Lightning fighter, which can definitely be tough and rigid with the Mirage 2000-5 without falling behind, even against the large-scale equipped F-16 fighters of Turkey, Greece's sworn enemy.

At this time, I also roughly understood the idea of Greece, which was obviously to make the lightning into an existence that could be used as the main fighter of Greece.

"Using Pratt & Whitney's PW-1120 engine, which is about the same size and weight as the original turbofan 10 engine of Lightning, we can complete the replacement work very quickly, and we can complete all the improvements in a year at most, so our recommendation is to use this engine."

Of course, Embraer's technical leaders know which engine is better, and the most important point is that if Pratt & Whitney's engine is used later, there will be more voices in the United States to support the Lightning fighter in the future.

Because there is such a strange phenomenon in the United States, whether it is F-15 or F-16, these two fighters are almost all generic F-110 engines when they are exported, so Pratt & Whitney has never made money in the F-15 and F-16 export market.

If the Lightning uses the PW-1120 engine, even if the Lightning and the F-16 have more all-round export conflicts in the future, at least Pratt & Whitney will firmly stand on the side of the Lightning, anyway, even if the F-16 wins, the engine is also the purchase of General Electric's F-110, which is essentially different from the purchase of PW-1120 after the lightning wins.
