For this promising electronic components manufacturing factory in the future, what it needs now is not Yang Hui to come to various inspections and investigations, but to continue to grow and grow.

After only a few cursory glances with Director Changhong Ni, he left the factory and turned to the development progress of the FC-17 joint fighter airborne radar that Yang Hui had been paying attention to.

To put it more simply and crudely, almost all state-owned factories cover an extremely wide area, which brings an advantage: at least the current Changhong Factory's civilian and military units are in one place, and even the scientific research center is not far from the factory.

Instead of going directly to the scientific research team to visit the radar development, he went to the next data room with Director Ni, where he saw all the information about the radar under development.

First of all, he skipped the various airborne fire control radar materials produced by the Changhong Factory before, and Yang Hui also chose to turn a blind eye to the Blue Fox radar that is now being mass-produced and provided to Southwest Science and Industry for use.

It wasn't until Yang Hui saw the new generation of radar data developed for the FC-17 fighter that he couldn't wait to take out these materials, and Yang Hui had all kinds of curiosity about this radar, and he had heard that Changhong Factory had publicized the development of this radar with the assistance of Israel, and Yang Hui wanted to see if this radar was like this.

Just opened the cover of the information, the first page said the number of this radar: JL7806, at a glance you know that this radar is a typical military fighter radar, but from this point alone. Yang Hui was definitely unable to tell the pedigree of this radar until he carefully looked through the information. Only then did Yang Hui understand what kind of radar this was.

At the end of 86, the project began to be developed, and in 87, it began to be officially put into intensive research and development. The X-band attribute of this radar pulse Dopre radar is obviously different from the Blue Fox radar band introduced by Changhong Factory, which can show that the radar does not have British origin.

Why? When it comes to the working band of this radar, in fact, the difference between the two adjacent radar bands is not too big, the British radar uses the I-band, the American third-generation aircraft radar uses the I/J-band, and the Israeli radar uses the X-band.

Most people know that X-band radar was later divided into I/J bands, but in the chaotic times of the 80s, the name of the radar band was still used in conjunction with the old and the new.

The radar of American origin is taken out for sale, and it is still said that this is the I/J band. Including the American radar used by the J-8 2 in Mukden is also called this, and now this 7806 radar does not use the American I/J band, which naturally shows that this radar has no American blood.

At the same time, there is no such thing as an I-band radar, so British origin is naturally ruled out, and the appearance of this X-band radar shows that this radar does have some inexplicable relationship with Israel.

Of course, if the Republic had its own mature radar band naming rules, Yang Hui's current set of identification methods would definitely be extremely unreliable. But the problem is that at this time, the naming of the military airborne radar bands of the Republic is still quite confusing, and many times the country of origin of the imported radar is called what band, and what band it is when it comes to the Republic.

Of course, this alone does not determine the pedigree of this radar. Such an arbitrary conclusion is naturally no different from the father-seeking party in later generations, and to determine what the situation of this radar is, you have to look at the data of other aspects of the radar, and find the information you need from the clues in all aspects.

Just when Yang Hui was looking for everything. Factory Director Ni on the side unexpectedly took out a contract and handed it to Yang Hui, and the cover clearly read: Outline of cooperation between China and Israel in the joint development of a new generation of light airborne fire control computers.

This thing came out. Yang Hui was also very speechless about his various behaviors just now, with this contract framework information. Is it still necessary to guess what is the situation of this radar being developed now?

"This 7806 radar is also a good choice to cooperate with Israel, Israel's radar development experience is richer than ours, and it is also reliable to cooperate with them in development, at least it is much better than our own independent development."

At this time, Yang Hui can say more, since both parties have signed R&D contracts, and have been developing for more than half a year, and Israel still has a mature semi-finished product, it must be acceptable in terms of time and funds.

As Yang Hui thought, after opening the contract, what caught his eye was not the cooperation treaty between the two sides, but the approximate data introduction of the EL/M-2035 radar developed by Israel.

Israel's EL/M-2035 radar sounds unfamiliar, but if you want to talk about who this radar is originally equipped with, it must be famous in the Republic, and this radar was also used as a Lavi (Lion) fighter jet, Israel's most ambitious autonomous aviation industry research project.

This aircraft is definitely a existence comparable to the French Mirage 2000, the two aircraft are actually very close in blood, both are the successors of the French Mirage 3, and under the guidance of the later generations of the Daddy Party, this Lavi has gloriously become the 'father' of the Republic No. 10 project.

I won't talk about the relationship between this Lavi and the Republic 10 Project here, but now I want to talk about the radar developed for this aircraft back then: EL/M-2035, as a radar used by fighters of the same level as the Mirage 2000, the caliber and weight are larger than the Blue Fox radar.

This is definitely the existence that Yang Hui wants to be entangled, whether it is Lavi or Mirage 2000, there is a big difference between the physique of the FC-17 fighter, the gap can be seen from the engine alone, one side is the engine that uses 9 tons of thrust, and the other side is the engine that uses 7 tons of thrust, which is completely incomparable.

There is also a difference in the radar, the EL/M-2035 radar weighs 135KG, while the Blue Fox radar weighs 90KG, the difference between the 45KG weight does not seem to be much, but when it is placed in the nose, there will be various problems, and top-heavy will definitely exist.

The FC-17 adopts the normal layout of large side strip wings, which can not be compared with the canard aerodynamic layout in terms of aerodynamic trim, and now if the extra 45KG weight is given, it is definitely a major challenge for the nose directivity data of the FC-17 radar.

If it is really installed with a 135KG radar, then the nose pointing speed of the FC-17 in the instantaneous disk may not be as fast as the old J-74.

If the weight of this radar cannot be controlled to less than 100KG, the FC-17 fighter can only choose another radar, as for the choice of what radar can only be said.

However, as long as this radar can be developed, it will definitely be useful, the lightweight FC-17 cannot be used, and the No. 10 project will definitely not have any burden to use this radar, so this new radar project developed by Changhong Factory and Israel will definitely not suffer.
