The problem of excessive radar weight has always been a major problem in the development of fighters, and the requirements for radar high performance are completely opposite to the low power consumption, weight, and volume of radar.

The most typical is that in the development of the Soviet Union's Su-27 fighter, the overweight of the radar is more serious than the current FC-17 using EL/M-2035, and the overweight of the radar is even a major factor that causes the hypochondria of the Su-27 fighter.

Yang Hui is deeply aware of the harm caused by the overweight of the radar, and now he also attaches great importance to the overweight problem of this radar, and asks questions directly without any disguise.

"If I'm not mistaken, this EL/M-2035 radar is the original radar used by Lavi fighters, although the final Lavi project should have been discontinued for various reasons, but the news we got from our side is that the weight of this radar is different from the radar weight required by our FC-17 fighters, which is more than the upper limit of 35KG that we can accept"

The latter words did not continue to be said, but almost everyone understood what Yang Hui was going to continue to say, and the FC-17 radar technicians who came with Yang Hui also frowned at the news mentioned by Yang Hui, exceeding the upper limit of the weight requirement of 35KG, which is definitely a rather tricky problem

Thinking of this, everyone turned their eyes to Director Ni of Changhong's side, this kind of major technical problem, if Changhong Chang can't come up with a satisfactory answer, I'm afraid that this Changhong Factory will be crossed out by Southwest Science and Industry from the list of radar suppliers for FC-17 fighters.

Under the scrutiny of everyone. This director Ni is light-hearted, and it seems that the problems that Southwest Science and Industry is worried about do not exist at all. Could it be that the Changhong Factory really has any way to deal with the excessive weight of the radar?

Director Ni smiled and patted the contract framework that Yang Hui put aside after reading it just now, this contract framework could not write all the details of the cooperation. The real full contract is not available now.

Of course, this director Ni did not plan to take out the complete contract, the scale of a complete contract is not small at all, and you don't want to read it in an hour or two.

"Haven't you said it all before! This time, we provided the FC-17 with the JL7806 radar, which is not the same as the EL/M-2035 radar, otherwise we signed a joint development contract with Israel, but a technology introduction or complete aircraft procurement contract. I can say that our 7806 radar is specifically tailored for the FC-17, and it is inherited from the EL/M-2035 radar. But there's more to it than that, and there's development and improvement. ”

Speaking of this, Director Ni also has a variety of expressions, for the 7806 radar under development now, the entire military research and development department of Changhong Factory has been holding its breath desperately, if the introduction of Blue Fox radar was the life of the military department of Changhong Factory, then the current 7806 radar is the future of the fire control radar project of Changhong Factory.

If it can be achieved, the Changhong Factory will be able to return to the mainstream of the Republic of China's first-line airborne fire control radar providers, and it can even be regarded as a first-class research and development unit, which can be regarded as a real Nirvana rebirth.

Without further ado, Director Ni took Yang Hui and his party of four to change into a set of clothes. Walking into the scientific research building of the radar, as the unit that produces the most military fighter radars every year in the Republic, the security force of the Changhong Factory is not weaker than that of the Southwest Science and Industry, after a lot of cumbersome registration. Only then can Yang Hui walk into the Zhengguang Scientific Research Building.

The first feeling of walking into the building is cool, I have to say that the current Changhong factory is really strong because of the blood transfusion of civilian projects, and the air conditioner is definitely a high-end thing in the eighties is also installed throughout the scientific research building.

It's not that Changhong factories can already produce air conditioners at this time. Therefore, it is a luxury to improve the scientific research environment for scientific researchers. In this 88 years, Changhong Factory is still tackling key problems step by step on the road of color television. Making air conditioners has never been thought of at all for Changhong.

At this time, the reason why air conditioning was installed in the scientific research building was because of the electronic equipment developed here. Whether it is a radar or a television, although it will be tested by the outdoor environment in future use, it is absolutely necessary to ensure the temperature and humidity of the experimental environment in the development process.

First of all, some necessary scientific research equipment needs constant temperature and humidity, and secondly, these radars that are still under development only have a simple working part, and they are not only the working part installed on the fighter, but also the refrigeration equipment.

In the third generation of fighters, the temperature needs to be controlled almost 24 hours a day, and the on-board refrigeration technology in flight, such as: the fuel is circulated through special pipelines to be used for liquid cooling of the radar, whether it is a variety of methods are used, anyway, the temperature of the radar must be controlled not too high.

Now the scientific research experiment is simple and rude, directly use the air conditioning to control the whole environment, the temperature may be higher when the radar is turned on and tested, then directly use the air conditioner to blow, how can the scientific research building in this case be hot, although it is a hot summer, but the scientific research building of the Changhong factory is extremely cool.

Walking into the project team, after Director Ni first went to explain the situation, a person who seemed to be very authoritative finally came out, and he thought that he should be the chief engineer or deputy chief engineer of the 7806 radar.

And when the scientific research director walked out, Yang Hui clearly saw the legendary bag through the moment he opened the door. It seems that it is a true fact that Israel participated in the development of the 7806 radar, which is technically Yang Hui can worry less.

The technical director obviously had a preliminary communication with Director Ni just now, and he was not surprised to see Yang Hui so young, and enthusiastically stretched out his hand to be polite together.

took Yang Hui to the small conference room on the side and sat down: "Since General Manager Yang personally came to our 780 factory to see the development progress of our 7806 radar, then I will carefully introduce the specific situation of this radar." ”

As he spoke, he wrote down the general data of some radars on the presentation board in the conference room, first of all, the working method of this radar: pulse Dopre; Frequency band: X-band; Weapons: Thunderbolt 8, Thunderbolt 11, C-801, cannon.

These simplest introductions also made Yang Hui very satisfied, Thunderbolt 8, C-801, machine gun must not be said, that is a must, and the Thunderbolt 11 missile mentioned here is the first medium-range air-to-air missile of the Republic that was finalized not long ago, that is, the first generation of British sky flash seeker and engine purchased by Southwest Science and Industry a few years ago, and the medium-range missile developed with the Hongqi 6 missile body of the magic capital.

It is said that the performance is not bad, quite praised by the army, the navy has begun to let the Southwest Science and Industry upgrade the purchased J-74 fighter fire control system, it seems that in two more months all the domestic J-74 can use this missile, and put into combat readiness.

Therefore, Yang Hui is still quite satisfied with the types of weapons guided by this radar, and short-range and medium-range missiles against the air, anti-ship missiles against the sea, and panacea cannons can all be used.

"Yes, it's pretty good in terms of radar-guided weapons, but I don't know what happens to the ground side of this radar? We had to have synthetic aperture topographic mapping, which was quite a challenge! (To be continued.) )
