In addition to the improvement of the power system and radar, other avionics systems may also need some improved design, but these do not require major surgery, but the update of the weapon system should be a more important place, and some of the latest airborne weapons also need to be equipped with lightning, which is mainly in the ground attack weapons. Pen fun and pavilion www.biquge.info

Overall, it was found that almost all of the new subsystems planned for the lightning upgrade and improvement were given to Bao Yuan by AVIC Southwest, and these technologies from AVIC Southwest to Bao Yuan are not something that needs to be tackled in key ways.

As for why the improved design of the lightning was carried out in Embraer, there must be a reason, mainly because the original lightning fighter design team of AVIC Southwest has been dismantled, and the technicians are either stuffed into the J-18 fighter project, or they are going to do the key project in the institute: the fourth-generation heavy battle bidding.

The only remaining backbone of the Lightning fighter design, only a deputy chief engineer who was responsible for following up all the designs of the Lightning at the time, was transferred to Brazil this time to join the technicians who had been stationed in Brazil before the convergence, and this formed the Chinese Lightning Fighter Technology Improvement Advisory Group.

Therefore, at this time, it is actually difficult for AVIC Southwest to pull out the design team of Lightning, which is a bit like the production line of the fighter jet is sealed for a period of time, although it still has the ability to continue, but due to the cost and cost is too great, it is generally not necessary to pull the team up.

Since the lightning fighter design team of AVIC Southwest has been scattered, it is certainly impossible to take over the upgrade and improvement task of Lightning, and it is okay to hand over the design work to Embraer, anyway, the subsystem provided by AVIC Southwest, plus it can take away 35% of Embraer's profits in the Lightning fighter project as a shareholder every year, and the total sum of zero and zero will find that although the lightning has been transferred, it can be transferred to Embraer to continue to develop. However, AVIC Southwest still occupies the largest share of the aircraft's profits.

In this way, Yang Hui is also happy to say that he can be regarded as satisfied, he can develop the J-7 series all the time, and he can still be the shopkeeper in the current lightning fighter era, and make a lot of profits in the project, which can proudly say that AVIC Southwest has developed the entire J-7 series to the extreme, and has also achieved Phoenix Nirvana, which is why Mikoyan is ashamed to come.

Careful people will find a problem when they see this, the republic's J-7 series of battles has finally come to an end, not only the production line is completely closed, but even the design team is going their separate ways, only when the J-7 series that is still in service in the army is active in the blue sky, it may also be able to arouse the incomparable nostalgia and emotion of those in the know for that era.

Perhaps, only when the Jianjiao 7A, J-74/5, and side plate lightning are returned to the factory for overhaul, can these guys be seen in the factory with familiar figures.

And with the withdrawal of the apprentices and grandchildren of the entire J-7 series from the aviation industry, the successors have also taken over step by step, the No. 10 fighter of the 0611 Institute, the J-18 of the 0112 Institute here, and the J-11 fighter of the Fengtian side, the republic of this plane has transformed to the era of third-generation aircraft at least ten years in advance.

...........

For the lightning fighter, Yang Hui still has some feelings, but with the end of the visit, everyone still shifted their minds back, at least at this time the various situations are relatively clear, and Yang Hui's trip to Brazil can be regarded as the final end, that is, to participate in the service ceremony of the comprehensive supply ship built by the Republic for the Brazilian Navy.

During this period, Yang Hui also walked inside the supply ship, and took a closer look at this modern comprehensive supply ship, after all, it uses the oil and water supply system provided by European manufacturing, which is the key equipment that the Republic has not yet served, and the supply ships of the Republic before were only oil and water supply ships, not comprehensive supply ships, so there is still a gap in technology.

But apparently Yang Hui didn't have the ability to make this supply ship pregnant with a glance, and just left happily after taking a look, but what made Yang Hui quite strange was that this supply ship was not equipped with carrier-based helicopters.

At this time, he did not think that the cause of this situation was that Brazil had not yet purchased a supporting carrier-based helicopter, and now Brazil is still bidding for carrier-based helicopters in various plans.

However, even if Yang Hui knows about this, it is impossible to say that the Z-18 will be pulled out to participate in the bidding for the carrier-based helicopter in Brazil, at least the technical complexity of the helicopter is higher than that of fixed-wing aircraft, so it is generally difficult for helicopter development units without sufficient technical background to be recognized by foreign markets.

To say that this whole trip to Brazil, in fact, did not get a major breakthrough in the help of AVIC Southwest, but it will not be said that empty-handed, just the day before Yang Hui was ready to leave, a completely unexpected order fell on the head of AVIC Southwest, it seems that this time the Brazilian government expressed a strong interest in the MPC-75 aircraft flown from AVIC Southwest.

Fortunately, they are only interested in the MPC-75, and they have no intention of making up their minds about the production line of the MPC-75, probably because they also know that after this aircraft has two final assembly lines, it will be difficult for Brazil to recoup the cost of building another one.

Therefore, the Brazilian side is still more pragmatic: "We need a turbofan-powered regional airliner for special aircraft modification, although we have considered purchasing Embraer's EMB-145 to use, but after evaluation, it was found that the fuselage of the 145 is too narrow and not suitable for our special aircraft modification, so we have taken a fancy to the MPC-75 platform, and we will use it to integrate Sweden's "Eriyan Eye" radar system to develop an early warning patrol aircraft. ”

This is definitely an unexpected situation, Yang Hui never expected that the Brazilian AWACS project that finally fell to the head of the EMB-145 in the last face, and now it is fortunate to fall on the head of the MPC-75, which is really surprising.

Brazil's last AWACS aircraft project is actually the introduction of the "Eitereye" radar system developed by Sweden, and after it is equipped with EMB-145, it has the appearance of an early warning aircraft, at least the previous one came in this way, but it is a pity that the Brazilian early warning aircraft made in this way by the previous face is actually a castrated product.

Not only Brazil's early warning aircraft was castrated, but even Sweden's own early warning aircraft belonged to children with cerebral palsy, neither of them installed a complete early warning aircraft system on the early warning aircraft, so the last Brazilian and Swedish early warning aircraft can not be regarded as early warning and control aircraft in the strict sense, there are no mission system facilities on board, and there are no system operators, and the aircraft can only transmit the detected radar images to the command center of the ground air defense system through the data link for processing and analysis. Then the ground command center directs the air tactical aircraft or ground air defense forces to fight.

So why this result, in fact, a large part of the reason is due to the lack of machine platform, but now it seems that Brazil is planning to settle down? (To be continued.) )
