Being able to improve the AWG-9 on the basis of the APG-71 itself shows that there is no problem with the technical route taken by the optoelectronic detection system company this time, and when the time comes, the original inverted Caglense radar of the Su-27 will be replaced, which is definitely a very big technological leap.

After all, this is not Yang Hui's specialty, and it is not necessary to force it to understand a wave, so it is better to prepare to go to the old classmates to catch up.

I have long heard that my old classmate is now in the 601 Institute, and this time he is already the chief engineer of the Su-27 localization project, but both of them know that this meeting will definitely not involve the Su-27 subsystem bidding.

On the one hand, Wang Yongqing will not, and it is impossible to release water at this time, he was able to be elected as the chief engineer of the Su 27 localization project at the age of less than thirty-five, how many people with seniority behind the 601 Institute are staring wide-eyed, eager to put people under the magnifying glass to observe carefully, as long as there is a slight wind and grass, that is hehe....

And to say that on the other hand, the reason is simpler, Yang Hui is absolutely impossible to take the relationship to take the project, not to mention whether AVIC Southwest will not be able to live without this project, 10,000 steps back even if the radar bid has failed, the scientific research team of the photoelectric detection system company will definitely not really have nothing to do, or no rice to cook.

For example, at this time, the AVIC Southwest UAV business has always been under the umbrella of the photoelectric detection system company, and the synthetic aperture terrain mapping radar, remote sensing and control system and other projects developed for several UAVs such as sea patrol, hellcat, and pastoral cat are impossible to starve to death anyway.

Or take a long-term view, considering that Changhong has introduced Israel's L-band T/R component production technology, although that thing is not suitable for use as a fighter airborne fire control radar, but with that thing to do back to the old business, combined with the technical advantages of the photoelectric detection system company, with C-818 as the platform to develop an export-oriented active phased array radar early warning aircraft, the performance must be good.

Or if you feel that you don't need to update the early warning aircraft technology too early, then using the L-band T/R components introduced by Changhong Company as the basis can completely carry out the development of the Aegis system of the Republic Navy, and this thing is actually not difficult for the photoelectric detection system company.

First of all, the relationship between AVIC Southwest and the Navy has always been good, if you want to participate in the bidding for the Navy's Aegis system, I believe that with the reputation and relationship of AVIC Southwest, the Navy will definitely welcome it, and this is only to get the project bidding qualification.

And from a technical point of view, in fact, it is not impossible, first of all, the radar antenna area of the early warning aircraft is definitely not smaller than the antenna of the shield ship, so at this time, the accumulation of hardware technology in the development of the early warning aircraft: electromagnetic compatibility, cooling and other technologies can have a very big reference for the Aegis system.

In fact, to put it bluntly, this Aegis system can almost be regarded as a phased array early warning aircraft system installed on the ship, and the goals and tasks that they need to deal with are actually similar, and the complexity of the two systems is probably the same, so as long as a large early warning aircraft can be developed, then it can be done if you want to develop the Aegis system, but the Aegis system depends on the demand.

Considering that AVIC Southwest has won the data link system contract of the Type 052B destroyer before, and is very familiar with the navy's shipborne data link, the various data of the entire warship in the later stage can be very closely combined with the data of the Aegis system, which is a big advantage.

So don't look at the photoelectric detection system company at this time seems to be in a situation where there is no rice to cook, it is just the appearance, as long as you are willing, it is a big project every minute, so Yang Hui really can't help with the relationship or something, there is really no need.

........

Old classmates meet each other! In fact, there is not much sensationalism, probably reminiscing about the past eventful years, and then talking about their respective recent situations in recent years, complaining about the unhappiness in their hearts, especially when the two are still in the same system and industry, men will unconsciously talk about various problems in the industry and so on.

In this way, we gradually talked about the Su-27 project this time, and this really revealed some so-called internal information that had not been disclosed to AVIC Southwest before, and this content can still be heard, at least this news is different from what Yang Hui heard in the previous face.

After comparing the situation of the previous one, this was followed in a timely manner: "It turns out that the situation is like this, it seems that the Air Force still has a very good opinion on the localization and improvement of the Su-27, and this vision is really not low, and it went directly to the Su-27M type, if this project can really be successful, it will be a powerful heavy fighter." ”

In fact, if you really want to say that this Su-27M, in the previous one, it was not able to finalize the finalization, but if you really want to talk about the ins and outs of this aircraft, it can probably be said that this is the concentration of all the improvement measures of the Su-27 family in the first two decades after the first finalization, it is an advanced technology verification machine based on the Su-27.

In fact, the Su-27M also had many code names, which were called Su-35 in the nineties (this should be distinguished from the new Su-35 after 2010), and later there were also Su-37 numbers.

This aircraft also uses a three-wing layout design, and the history of the three-wing layout of the Su-27M can be traced back to before the Su-33 carrier-based fighter, and the three-wing layout of the Su-33 is transplanted from this aircraft.

The Su-27M not only adopts a three-wing layout in aerodynamics, it also completely redesigns the new cockpit avionics, and the early avionics full of instruments have finally been replaced, and the layout of one flat and three down appeared for the first time in the Su-27 family, and the later Su-30 series avionics are transplanted from the basis of the Su-27M.

This aircraft has undergone major surgery on the power system, and in the early plan, it was changed to the Al-31FM engine with a digital full-authority electronic control system, and then it was soon not satisfied, and it was changed to use a 14-ton 31F engine with greater thrust again, and it was necessary to install vector nozzle technology, and this technology was later used to pit the vector thrust engine used on the Su-30MKI fighter jet of the third brother.

Because the engine uses a full-authority digital control system, plus vector thrust control, and the aircraft uses a new digital radar, so that the improvement of the flight control system of the new aircraft is reflected.

On the basis of the original analog fly-by-wire, the flight controller was directly changed to a three-axis and four-redundancy digital fly-by-wire design, and the static instability design of 20% was relaxed again in the case of subsonic flight, and then the radar and engine control were integrated into the flight control, which directly realized the legendary integrated cross-linking design of fire flight propulsion.
