The two of them chatted and walked over to the two wings that were placed on the shelves and had not yet had time to put them back on.

"That's right, senior sister."

Chang Haonan stared at the wings in front of him for a long time, and suddenly turned around:

"When you change these two planes, remember to enhance the data transmission capacity of the electrical interface on the pylon."

After a pause, he added:

"If there is not enough space inside the old wing, at least upgrade the two pylons of No. 3/7 and connect them to the multi-function display in the back seat."

"Ah, of course this is no problem, there is still room for upgrading the two pylons alone."

Compared with the previous situation where she was only responsible for the 83 Project, Yao Mengna is now responsible for a lot more work, and even barely leads the overall situation with Tang Changhong, and her understanding of the modification situation is naturally much more comprehensive:

"But if you upgrade the pylons...... Is there any special ammo that needs to be loaded? ”

In 1997, Huaxia's airborne weapon model was still quite barren, and the only precision-guided munition of the J-7 was the YJ-81 missile, which had a range of 50km and could only be used for anti-ship because of its poor ability to deal with clutter, and did not need to have too much data communication with the carrier aircraft before launch.

In fact, the YJ-81 can even be launched without target information, and try its luck after the terminal radar is turned on.

"Ammunition...... Almost."

Strictly speaking, jamming pods should probably be considered equipment, but in literary terms, it is not impossible to see electromagnetic waves as invisible ammunition:

"The thing we came to test this time, if it comes out normally, it should be able to be installed on the J-7."

"Got it." Yao Mengna nodded.

"Senior sister, is there anything you need technical help with?"

When it comes to the choice of electronic warfare platform, Chang Haonan still can't help but ask.

"It's nothing yet, in fact, the upgrade plan we have set up so far is very conservative, almost all of the things you took me to do in Shengjing before, so in general, it is quite smooth, according to the current plan, these two planes can be modified about next month and handed over to the army for trial."

Yao Mengna had a faint pride on her face.

If at the beginning, she chose to stay in Hojing so as not to be too far behind by Chang Haonan's footsteps, then after nearly a month of work, she has begun to have some feelings for these two planes born through her own hands.

……

The aerial test of the pod was conducted in the afternoon of the second day, when it was cloudy but rainless.

The main reason is that there is no corresponding transportation and storage standard for the engineering prototype for the time being, and a complete inspection is required after being transported to Hojing by air 8, which is delayed for half a day.

After lunch, Chang Haonan finally saw the rather mysterious No. 713 electronic equipment verification platform at the end of the tarmac.

At this time, its nose was holding a black radome, judging from its appearance, it should be the Type 1473 radar used to test the J-10.

It is also the model that the J-7A plans to reequip in the future.

However, Chang Haonan's pod does not need to occupy the most valuable nose space, the small one is hung under the wings, and the large one is hung under the belly.

Chang Haonan and his entourage, who had just finished the ground inspection, watched the ground crew not far away, and installed the two pods on the Y-7.

Compared with the test flight of the plane itself, this electronic platform test is basically not too risky for the flight personnel, so the overall atmosphere is relatively relaxed, and the three pilots shook hands with Chang Haonan and Guo Lin in turn, and then turned to board the plane.

With the roar of the engine, the No. 713 dragged two faint black smoke off the runway and gradually disappeared into the clouds.

Normally, this kind of test is best to take off several fighter jets as the target of interference, so that the altitude and position of the test can be basically unlimited, so as to avoid affecting the residents or other equipment on the ground.

However, in the past few years, there were only a few planes in the whole of China that had over-the-horizon combat capability, and it was certainly impossible to lend them casually, and Chang Haonan had a very tight schedule, so in the end, they had no choice but to use the artillery sighting radar of a nearby antiaircraft artillery regiment as an imaginary enemy of the "blue army" in the name of air-ground joint exercises.

After climbing to a sufficient altitude and entering the level flight state, the No. 713 aircraft quickly turned its nose and flew to the predetermined test area in Hongnong City to the northeast.

The anti-aircraft artillery regiment of the 47th Division of the 139th Army was stationed there.

At the same time, Shen Yanzheng, the commander of this antiaircraft artillery regiment, was standing slightly nervously behind the command position, looking at the 18 Type 74 twin 37mm antiaircraft guns arranged in a semi-circular shape on the preset position in front of him.

This is equipment that other similar units of the army can cry over.

Although the appearance is similar to the previous Type 65 Double 37, the 1035 analog commander, the two-meter rangefinder and the Type 10 gun sighting radar have been added, and the anti-aircraft gun itself is also equipped with a follower motor, which can automatically obtain and solve the target elements, and there is no need to rely on manpower to drive the high and low machine and the direction machine.

Aside from having to be dragged by trucks and taking the time to set up positions, it doesn't seem to be much different from those modern fully automatic anti-aircraft artillery systems.

And Shen Yan also specially sent an anti-aircraft artillery battalion with the best training performance in his hands.

In fact, he himself used to be the battalion commander of this battalion, and because he led the team to the top in a military region-level competition, he was promoted to deputy regiment commander and eventually promoted to regiment commander.

Although he had long known that the actual purpose of the so-called joint exercise was to test the test flight institute, and the opponent was not the air force that he had always expected to compete head-on, but it didn't matter.

In this era, the army was too hard, and the anti-aircraft artillery regiment usually had few opportunities to shoot target planes, and many times they could only practice against the air.

Anyway, the fighting spirit of the commanders and fighters at all levels has been aroused, and he has promised that if the confrontation exercise is won, he will give the whole regiment a meal at noon tomorrow.

As the estimated drill time approached by minute by minute, the frequency of Shen Yan raising his hand to look at his watch became more and more frequent, and from time to time he had to glance at the situation on the radar screen not far away.

Obviously, he was also a little nervous.

However, the working group of the test flight institute that has been standing behind him has a stable mentality.

They are not soldiers, they are only responsible for faithfully recording everything that happens, and they will not and cannot have Shen Yan's competitive spirit.

"Report, radar found targets, number 6, direction 34, distance 20km, altitude 1000, speed 350!"

The loud report of the radar operator broke the silence inside the command post.

Originally, due to the existence of an automated command system, this step was not required.

However, considering that there were still test flight institute personnel at the scene who might not be able to understand the radar data, it was still reported.

"Six?"

Shen Yan's expression froze, and he looked back at the engineers in civilian clothes.

The first person shook his head and said that there were not so many planes of the same type in our test flight institute, and only one took off.

“TMD……”

Hearing this answer, Shen Yan knew that his radar was jammed no matter how he was.

The operator skillfully followed the standard procedure, but it didn't work.

The target was only 14 kilometers from the position.

"Calculate all the targets and let the rangefinder prepare for manual disposal, even if it is blinded today!"

Shen Yan took off the hat on his head and held it in his hand, picked up the walkie-talkie with the other hand and ordered.

As a commander who has been evaluated as excellent by the whole army, he naturally has a set of things that he can adapt to on his own, and he is not a rookie who is left without technical equipment.

The originally silent position instantly became hot.

Then the anti-aircraft artillery positions were fired in groups of three, under the command of radar, and several rounds of firing were carried out.

The smooth cooperation between the personnel in different positions made Shen Yan's face finally better.

However, the good times were short-lived, and observers reported not seeing any targets flying towards them.

"Report to the head of the regiment, the radar shows that the target aircraft is in the air!"

The radar operator's voice rang out again.

It was clear that all the six he had just caught were false targets.

"Quick, get ready to reload!"

“……”

However, as soon as his words fell, a small black dot appeared from the horizon in the direction of 34, and continued to grow in everyone's field of vision.

The observer with a rangefinder in his hand quickly reported the model of the aircraft.

A Y-7 has a speed of about 350 and an oblique distance of about 3km.

At this moment, Shen Yan's face turned completely white-

If this was on the battlefield, and what flew over was not a slow transport plane but an attack plane, I am afraid that his battalion-level air defense position would have to be reimbursed.
