Liang Shouye gave Lu Jiadong a thumbs up again and again, and was full of praise in his words, applying the technical principle of the "bilateral" fire control system used on the H-6 to the modification of the A-4 "Sky Hawk" attack plane.

First, both planes were equipped with bombing radars, and their main task before the modification was to bomb in the air; second, the H-6 was only fused with the YJ-6 anti-ship missile after the ZJ-6 missile firing command instrument was installed to become the air-launch platform for the anti-ship missiles of the Chinese Navy's naval and air forces.

Finally, and most crucially, China has mastered the technology of modifying the H-6, and for example, Liang Shouye has participated in the development of the ZJ-6 missile firing command instrument that is used to support the YJ-6 and the modification of the H-6.

"Chief Master Liang, don't say that, I just had a flash of inspiration, even if I can't think of it, Chief Master Liang will find this solution when he goes back!"

Listening to Liang Shouye's praise again and again, Lu Jiadong still maintained an indifferent smile, he was not modest, but to tell the truth, in fact, with Liang Shouye's solid foundation, profound skills, and the experience of participating in the modification of the H-6 and the development of the ZJ-6 missile firing commander, Liang Shouye could not have imagined that this set of modification technology, which has become increasingly mature, is just too refined, and some authorities are confused. I just didn't think of it for a while!

"What is ability? What does it mean to have a deep foundation? Can you think of using the principle of fire control technology of the modified H-6 to modify the A-4 'Sky Eagle' is the best illustration of this!" As soon as Lu Jiadong's words fell, Liang Shouye waved his hand at him. Then he continued not without admiration:

"Without extensive experience, without a solid foundation, without strong technical reserves, it is impossible to come up with it, let alone find another way immediately after the expected plan does not work, this quick wit and determination. Even I, an old antique who has been engaged in aerospace for half my life, is far from comparable!"

Lu Jiadong knew that Liang Shouye was about to start praising at length again, so he quickly changed the conversation and said, "No matter what." Now that we've found the direction, let's hurry up and start implementing it!"

"En!" Liang Shouye nodded thoughtfully, he also knew that time was pressing now, so he pointed towards the station: "Go." We'll go back and discuss!"

That's it. Lu Jiadong and Liang Shouye soon returned to the station of China's military technical team, and it was not long before a plan for modifying the A-4 "Sky Eagle" fire control system based on the technical principles of the H-6 fire control system was preliminarily completed under the outline of the two.

Lieutenant General Messi, who received the new plan, was also taken aback, and he did not expect that Lu Jiadong and his party would be able to come up with the modification plan of the A-4 "Skyhawk" attack plane so quickly, and read it several times. Only then did I believe that the new plan submitted by Lu Jiadong was not a perfunctory coping.

With a stroke of the pen, he directly transferred the two A-4 "Skyhawk" attack planes parked at the Rio Grande Air Base to the Chinese military technical team for refitting. In the evening of the same day, a Chinese military technical team headed by Lu Jiadong was stationed in the No. 3 hangar of the Rio Grande Air Base to conduct a comprehensive survey and inspection of the two A-4 "Skyhawk" attack planes

"Xiao Lu, you're right!" After opening the electronic equipment compartment at the nose of the A-4 "Skyhawk" attack plane, Liang Shouye held the A-4 maintenance equipment manual provided by Argentina in one hand, and while comparing the various components of the electronic equipment cabin, he couldn't help but nod:

"The bombing radar, the heading reference gyroscope, the inertial navigation stabilization platform, the heading attitude system, the altitude and speed sensors, are all perfect, except that the size is several orders of magnitude smaller, and the airborne equipment of our H-6 is not much different!"

"That's true!" As soon as Liang Shouye's voice fell, Song Xiaoxu, who was checking the overall wiring of the entire aircraft on the top of the plane, straightened up and said:

"All that is missing is the command instrument, the guidance radar and the weapon pylon!"

"Therefore, as long as the ZJ-8 missile command and control instrument we brought is compatible with it, and the weapon pylons are modified, the modification of the entire aircraft will be completed!"

"What about the guidance radar?" As soon as Hu Qinghua finished speaking, Xu Yuanchao, who was checking the dashboard and joystick in the cockpit, suddenly raised his head from the cockpit and asked loudly, but before Hu Qinghua could answer, Song Xiaoxu, who was standing behind him, spoke first:

"Didn't you say it in the afternoon, the active radar will use the built-in radar on our C801 missile to complete the search and complete the calibration of the final shooting elements!"

"How else can we say that the fire control system of our modified A-4 "Skyhawk" attack aircraft is based on the principle of the naval aviation's H-6, and the joint point is here!"

When Song Xiaoxu's voice gradually fell, Liang Shouye took the conversation, and then took a portable detector and inserted it into the interface of the AN/APG-53 radar, and then popped out several sets of numbers, Liang Shouye continued as if teaching students while recording:

"Because the principle of the fire control system used to install the YJ-6 anti-ship missile on the H-6 is like this, using the scanning and tracking system and information monitoring technology, the moving base heading horizontal positioning technology and the Kalman filter technology, so as to improve the performance of the fire control system, so this system is also called the 'bilateral' system.

It is precisely for this reason that we have skillfully combined the 254 bombing radar on the H-6 with the ZJ-6 missile command and control instrument and put it on the A-4 to integrate its AN/APG-53 radar with the ZJ-8 missile command and control instrument that controls the C801 anti-ship missile in the same way.

In this way, the AN/APG-53 radar scans the signal echoes are stored and displayed, and at the same time, the real-time navigation information entered by the navigation system is displayed. Mark these echo signal points, and in the next scanning cycle, the ZJ-8 missile command and control instrument will automatically follow the movement of the aircraft. Change the echo annotation, so as to form a continuous track annotation for each echo signal, so as to achieve the purpose of tracking while scanning!"

"This kind of automatic tracking tracking, although not as high precision and high-speed continuous tracking as high-performance fire control radar, is very suitable for tracking long-distance small-angle displacement targets or slow targets, and it is enough for anti-ship operations!"

After Liang Shouye finished speaking, Song Xiaoxu, who was standing on the plane, added. And Xu Yuanchao, who was sitting in the cabin, couldn't help but nodded suddenly:

"Oh! I see! But you've been talking about it for a long time, and you haven't talked about active radar!"

"Isn't it obvious that Chief Liang and Xiao Song said this?" As soon as Xu Yuanchao's words fell, Lu Jiadong asked with a smile. This made Xu Yuanchao couldn't help but pause, and then frowned and thought for a long time without knowing the essentials, and just as he wanted to open his mouth and continue to ask, Lu Jiadong's calm voice sounded in his ears again:

"That's because we're using a patchwork retrofit solution. So the fire control system itself cannot be fully integrated with the missile. As a result, the initial ground velocity and initial yaw velocity of the missile cannot be measured and entered into the firing elements of the missile, so it is necessary for the anti-ship missile itself to measure the values of these two initial velocities at the time of launch.

However, fortunately, the DM-3 active radar on our C801 anti-ship missile applies the Doppler system, which can measure these two values, so the problem is not too big. Of course, this fire control system, which is impossible to provide all the data of the missile launch, cannot be compared with the world's advanced fire control radar system. But at least it reached the level of the fire control system of the seventies in the USSR, which is more than enough for Argentina !"

"Now I finally understand!" Xu Yuanchao said, then gave a thumbs up from the cockpit to the people outside, and said to the people outside with admiration:

"You are really well-deserved military experts, it is not much to say that it is a treasure of the country, to be honest, I am distressed and relieved to see you busy day and night, and I feel distressed by your hard work, and I am at ease that with you, our backbone will become harder and straighter, but"

Xu Yuanchao first spoke very loudly with an excited look, but as he spoke, his whole person was gloomy, causing many members of the Chinese military technology team present to be a little embarrassed at first, and then there was a feeling that he couldn't stop it, so he couldn't help but cast all his curious eyes on the cockpit of the plane where Xu Yuanchao was sitting.

However, Xu Yuanchao didn't seem to notice the focused gaze, but looked at every instrument pointer in the cockpit of the A-4 "Skyhawk" attack plane with a burning envy, and then stroked the head-up display directly in front of him, shook the joystick with his hand, and subconsciously made a few flight movements:

"When will we be able to have such a good aircraft ourselves, strong, durable, and capable of launching missiles, when will we have it?"

Listening to Xu Yuanchao's words, everyone present stopped what they were doing, looked at each other, silent, Xu Yuanchao, the words of this ace pilot of the naval aviation were like a muffled thunder, stirring in everyone's hearts, when will we have attack fighters in China that can launch missiles?

"Don't worry, far exceeded, I believe that in a few years, you will be able to fly our own special anti-ship missile fighter!" Everyone's questions were quickly answered, and the person who said the answer was none other than their core soul Lu Jiadong:

"And I assure you, its performance will far exceed that of the A-4 and the 'Super Army Banner'!"

"Really?" Xu Yuanchao asked in disbelief, and Lu Jiadong's answer was very crisp and confident:

"Really!" (To be continued.) )
