Pellehaq led the team.

When he got out of the car, he saw Qin Feng, and he was stunned for a moment, and then said, "Aren't you in Chengdu?" ”

"Yes, I'm not in Chengdu. Welcome, Mr. Pelehaq. Qin Feng stretched out his hand, seeing that the relationship between the two was very friendly, and everyone present was relaxed, now, Qin Feng could be a pillar.

"Let's go, let's go in and have a look." Qin Feng took the initiative to take on the important task of receiving VIPs and took them into the assembly workshop, at this time, several Jian-82 fighters were carrying out the final assembly in an orderly manner.

"Spouted bottle?" When he saw the plane for the first time, Pelehaq was stunned.

Up to now, the J-82 fighter is still a confidential project, this fighter represents the highest level of domestic military aircraft development, the outside world may observe this aircraft from satellite photos, but when you see the actual aircraft, you will still intuitively think that this aircraft is the Soviet Union's Su-15 fighter.

Su-15 fighter, is a Soviet Union in the sixties designed a special interceptor, this aircraft in order to meet the requirements of high speed, the use of a slender fuselage, both sides of the air intake, the tail is in the form of two engines, on the whole, and the air beauty man is really a little similar.

However, if you look closely, there is still a big difference, for example, the J-82 fighter has a high bulging back, which is inherited from the J-7, and its cockpit canopy is not bulging, it is almost an enlarged version of the J-7.

"No, this has nothing to do with the Su-15, this is a fighter developed and produced by ourselves." Qin Feng explained.

Although the appearance is similar, but it is definitely the same way, the mission of these two fighters is to intercept, under the existing technical conditions, it can only be such a layout.

Pelehaq nodded: "yes, it doesn't look like it in many places, let's take a look at its nose." ”

The entire fighter, the main parts of the avionics, are concentrated in the nose, at this time, these fighters are being assembled, some fighters are not covered with a radome in front of the hood, you can see the flat nose in front of the nose, there is a parabolic antenna.

This has long been eliminated by the West, even if it is a backward technology, it also uses an inverted card antenna, this ancient parabolic antenna, should be thrown into the garbage heap.

Looking at these devices, Pelehaq felt a sense of satisfaction: "It seems that you are in urgent need of replacing our advanced avionics, please rest assured, we are very experienced, and I believe that this project will progress faster than the J-7 CP project of the tripartite cooperation." ”

J-7 CP has been a few years, and everyone is still fighting with each other, but the current project is different, it is very simple, that is, Grumman company will install avionics equipment.

"Can you bring the avionics equipment and modify it with us?" Qin Feng asked, from beginning to end, Qin Feng had doubts about modifying this kind of aircraft in the United States, and now that he saw the person in charge of the other party, he couldn't help but ask again.

"Of course not, it's too backward here, we don't have the necessary equipment and instruments, and besides, our workers definitely don't like to work here." Pelehaq simply refused.

In front of the nose is the radar antenna, and behind the antenna, there is the equipment compartment.

The equipment compartment of the J-8, like the J-7, is stacked up, from bottom to top, layer by layer, and if you want to dismantle the equipment below, you need to disassemble the top one by one.

At this time, Western fighters are already in the form of plug-in boards, just behind the radar, under the front of the cockpit, the covers on both sides can be opened, and after opening, the circuit boards are inserted from both sides, and once they encounter problems, they can also be quickly disassembled and replaced.

This is a different design idea, a fighter jet, it must have a high enough maintainability.

"We need to make improvements here, and all the equipment here is rearranged, which is a big project! It seems that our retrofitting costs will definitely not be low. ”

When it comes to doing business, Grumman is definitely a good hand, and they say this now, of course, to ask for a higher price.

When Qin Feng heard this, he felt a bad chill, these hateful capitalists, when they went to negotiate with Tu Lao, the improvements were all determined after repeated quarrels, if you can't carefully consider every issue before signing the contract, there will still be endless disputes in the future.

Thinking of this, he was going to refute, what's so difficult about this, dismantle it all, and then transplant the avionics layout of your F-16 nose directly, anyway, it's the AN/APG-66 radar of the F-16.

Just as he was about to speak, Pelehack spoke again: "In particular, we have to fully replace the 1553B data bus, there will be a large number of sensors, all need to find a new position, the design of many components needs to be modified, and our inertial navigation system, we also need to find a suitable position to install, the front of the nose looks a little crowded." ”

Inertial navigation system! This sentence reminded Qin Feng.

In the fire control system, radar is well known to almost everyone, and without a good radar, it cannot be called an advanced fighter.

However, in addition to radar, there is a very important thing in the fire control system, which is the inertial navigation system!

When you take off, how do you know where you are now? It is to rely on the calculation of the inertial navigation system, especially when performing bombing missions, it can take you to fly to the target accurately at ultra-low altitude, and on the Mirage 2000, Qin Feng has experienced the power of the inertial navigation system! In the past, the range of the aircraft was relatively short and inertial navigation was not used, but the Jian-8 fighter had a larger body and a longer range, so an inertial navigation system was urgently needed.

"Inertial navigation system?" Qin Feng couldn't help but ask.

"Yes, it's our LN-39 inertial navigation system from Litton, which is also the standard inertial navigation system of the U.S. Air Force, with a positioning accuracy of 0.8 knots per hour. The average inter-fault illumination time is 2 others, just saying these data is enough to make people enviable.

At the beginning, the J-7 was small and did not introduce inertial navigation, but now it has finally been introduced on the J-8.

Qin Feng immediately thought of another thing, if these systems were introduced, it would also be equivalent to storing technology for Project No. 10! After all, Project Ten also needs these things.

As for the bus technology, it is also an international standard, which can greatly simplify the number of cables inside the fighter, just like a network cable, all the information can be transmitted in it, and at the same time, this is also a basis for the realization of the glass cockpit.

"I think that this part of the space in front of the landing gear can be used, and it is also convenient for maintenance operations on the ground from here." Qin Feng said, at this time, he became excited again, the introduction of the Jian-8 project this time is also very meaningful.
