The military-industrial scientific research system of the academic master.

Inside the airport, minibuses are a bit inconvenient to use.

Especially when you have to go to the apron or even the taxiway later, the bigger the car, the greater the impact on airport dispatch.

Therefore, everyone got on several soft-top Cheetah off-road vehicles and headed towards the tarmac.

At this time, the four JH-7As that had just descended also landed on the runway in groups of two.

This should be the fourth in the air formation.

Of course, the usual training processes of each formation are separate, and they are not necessarily organized in the order of review. Otherwise, Zheng Liangqun's interceptor wedge team would still be in the sky.

"After entering into small batch trial production last year, the production speed of the JH-7A has increased significantly this year. The 5th Regiment of the 15th Air Force Division and the 6th Regiment of the 18th HNA Division have begun to refit at the same time. In particular, the 18th Regiment has formed its first The complete J-7A brigade.”

Zheng Liangqun looked almost intently at the four aircraft not far away that had thrown away their drag chute and entered the taxiway, and said to Chang Haonan.

海航6师18团属于东海舰队，这个师之前还有一个装备了老型号歼轰7的16团，和一个装备轰6D的17团，显然是作为对海打击的拳头部队所建设的。

Even though the JH-7A model has become something that no one pays much attention to after more than 20 years, at this time, it is definitely the little sweet that every unit is vying for.

Chang Haonan even heard that some fighter units said that since they are called fighter-bombers, it would be okay for us to suffer a little loss and replace ourselves with some...

Of course, the focus of fighter-bombers is still on bombing. Both beyond visual range and maneuverability are not the same as multi-purpose fighters.

So they said that.

But it is enough to prove the popularity of this model.

When the distance got slightly closer, Chang Haonan suddenly discovered that these four planes were not HNA's numbers starting with 8.

"So these four are aircraft from the 5th Air Force Division?"

Ding Gaoheng, who was sitting in the passenger seat, turned around and asked.

He is not a member of the parade command organization, so it is naturally impossible for him to know the formation situation well in advance.

"Correct."

Zheng Liangqun nodded:

"Initially, this formation plan was called a naval aviation formation, consisting of four Hainan Airlines JH-4A aircraft. However, by the time the official decision was made in the second half of last year, the equipment capacity of the JH-7A aircraft had already increased."

"So after discussing with Commander-in-Chief Li, we decided to rename this formation the Fighter-Bomber Formation, and reduce the number of J-7Es in the next formation. After all, the J-7 is nothing special. Then we will add a naval aviation wedge with five old-model J-5s."

"After all, the deployment of troops for military parade cannot affect the combat effectiveness of front-line units too much. It is impossible to really remove all the cutting-edge models."

As if to provide explanation for Zheng Liangqun's words, just as several cars parked on the tarmac, the outlines of five aircraft appeared vaguely in the distance again.

"Director Ding, Mr. Chang, binoculars."

After a few people got out of the car, Zheng Liangqun brought two telescopes from the makeshift command room nearby and handed them to them respectively.

Ding Gaoheng immediately found a slightly shady position, raised his telescope and looked at the horizon.

Chang Haonan was not in a hurry.

After all, when he modified the JH-7 two years ago, he had already taken apart the model inside and out.

"Is the formation training going well during this period?"

Chang Haonan vaguely remembered that during the military parade training in his previous life, another JH-7 was damaged due to operational errors.

"Smooth, pretty smooth."

Zheng Liangqun was about to raise the telescope, but after hearing Chang Haonan's question, he put it down:

"The Guihang Group developed a simple version for us based on the formation flight rangefinder in the nose of the J-9 aircraft that can be attached to the wing pylon of the front aircraft. Although the effect is not as good as the one used by the performance team, But it’s better than nothing.”

He said and pointed to the four JH-4As that had already driven onto the taxiway.

Chang Haonan raised the telescope, and sure enough he saw a small, inconspicuous device hanging on the wingtips of each aircraft. It should be the one Zheng Liangqun was talking about.

In 99, the underwings of the aircraft being reviewed were relatively clean, and they did not hang bombs on the fighter planes like they did later (and of course during the founding ceremony).

The main reason is that airborne ammunition also has a lifespan. At present, the Air Force is still relatively poor and cannot afford to fly hundreds of aircraft with live ammunition at once.

But now, these aircraft have auxiliary fuel tanks and ammunition hung under their wings.

Although judging from the color scheme, it should be a training bomb, but it also adds a lot of momentum to the fleet.

"What about the mechanical condition of the aircraft? Especially the JH-7A with a new engine?"

In non-war years, military parades are basically high-intensity actions, and the relevant data are still very valuable.

Compared with the few turbofan 10s specially sent by the turbofan 10 project team to support them, which flew directly from the combat troops, the JH-7A, which is uniformly supported by the air force ground support units, is obviously more representative.

"very good."

After Zheng Liangqun finished speaking, he turned around and shouted into the distance:

"Team Leader Chen!"

After a while, an officer with the rank of colonel and wearing Air Force camouflage uniform ran over from the side, stood at attention, and saluted the three of them.

For a colonel, he looked very young, appearing to be in his early thirties.

"Chen Qin, leader of the 9910 project air formation service support team, please give instructions!"

"This is Comrade Chang Haonan, who is responsible for the overall design and production optimization of the turbofan 9A. Please report on the guarantee status of this model."

Zheng Liangqun ordered.

"Yes!"

Chen Qin took off the thread gloves on his hands, and then took out a tattered notebook from his jacket pocket:

"The fourth formation's four JH-4A aircraft have flown a total of 7 hours since the centralized training, without any flight accidents. According to the support manual and daily post-flight inspections, a total of 85 parts involving the turbofan 9A engine were replaced normally. , on average, each flight hour corresponds to 107 maintenance hours, of which 34 maintenance hours are related to the engine... If the commander needs it, I still have all the maintenance and repair logs from the centralized training to the present!"

"Compared with the J-H-7 of the fifth formation, the average number of parts replaced by each engine of the Turbofan 9A is only 202% of that of the SPEI MK45, and the maintenance man-hours corresponding to each flight hour is 55% of that of the SPEI, and it is not in the maintenance process. A fault was discovered that required complete disassembly of the engine..."

"..."

As the leader of the service support team, Chen Qin is in charge of all aircraft support work at WQ District Airport, so these data will naturally be concentrated in his hands.

But it's one thing to get the data, it's another thing to compile it specifically and carry it with you.

No wonder he became a colonel at such a young age.

Being specially selected to provide military parade support definitely reflects the trust of superiors.

In short, to sum up, the Turbofan 9A has completely surpassed the SPEI MK202.

Realizing this is not very important to Chang Haonan.

After all, the difference between an engine from the late 90s and an engine from the 70s is nearly 30 years.

But it is important for our Air Force comrades.

After changing to new equipment, especially new domestic equipment, pilots will be a little worried.

At this time, even if the technicians say 11,000 words, they can't compare to the opportunity to pull out the old and new models and put them together for comparison.

The difference is immediately apparent.

When new troops change their uniforms, it will be easier to accept psychologically.

"Director Ding, Mr. Chang."

After Chen Qin finished his report, Zheng Liangqun nodded, indicating that the other party could go back to work first, then turned around and looked at the two of them:

"I have prepared a surprise for you two today."

As he said that, he stretched out his hand and gestured to the taxiway not far away.

Chang Haonan turned his head following the other party's direction.

Then his mood perked up instantly.

While listening to Chen Qin's report, the 9 aircraft that had just landed, as well as the other 3 J-H-7 and J-H-7A aircraft as backup aircraft, a total of 12 aircraft, were already forming a long queue over there, heading towards the shutdown together. Coming from Ping.

12 aircraft, not a particularly large number.

But the location where Chang Haonan and others are located is not an absolutely high place.

So from their perspective, it really feels a bit like an "elephant walk"...
