The Military-industrial Scientific Research System of the Academic Master Chapter 274

Chapter 274 Old models also have new spring

 The general anti-radiation missiles used by China in the previous life were the kh31P and the YJ-91 developed on its basis.

The range exceeds 150km, the speed is Mach 3.5, and the 100kg super large warhead can destroy the entire radar even if the opponent shuts down and runs away.

It is a hero among anti-radiation missiles.

But this thing doesn't seem to be very complicated. In fact, it requires an integrated ramjet engine that China cannot yet make. It is not a model that can be built quickly and flatly.

Therefore, when the Thunderbolt 11 completed the air-to-air target test at the Dingxin base, Chang Haonan took the opportunity of the celebration banquet to mention to the staff of the Second Bureau of Electromechanical Engineering that the relatively thick body of this model could be used to modify a Light anti-radiation missiles are coming.

Because air-to-surface weapons have an inherent advantage in gravity potential energy, and they do not need to be as fast as air-to-air missiles, they can replace slow-burning propellants, and the range should be much better than the 30km of Thunderbolt 11.

 More importantly, it does not involve too many new technologies and can be produced and equipped with troops in a short period of time.

 Let the aviation force have something to use first, and then get familiar with the tactics.

Although it is said that it is better to let people wait for equipment rather than let equipment wait for people, the actual situation is that if you do not have even the most basic abilities, void practice is likely to go in the wrong direction, and it is better not to practice at all.

  I just don't know if there is anyone promoting this anti-radiation model and what the progress is.

The Second Bureau of Mechanical and Electrical Engineering is a unit of the aerospace system. Chang Haonan has not dealt with them much so far, at least not familiar enough to get all kinds of information by just making a phone call, so he simply entrusted Guo Lin, who has returned to Jinling, to inquire. .

As time goes by, this electronic combat flying leopard that everyone has high hopes for is increasingly revealing its final image on the drawings.

Since most of the aircraft modification work had been completed before Chang Haonan got involved, and the amount of subsequent modification work was not large, it soon came time to return to the blue sky.

Of course, test flights are quite serious matters, and it's not just about finding a pilot to fly around in the sky.

ˆ Relevant data recording and collection work, as well as flight safety assurance, require assistance from the flight test institute.

　　If there are too many people, you will need to queue up.

When Chang Haonan went to apply, he was told that a new model aircraft was going to be transferred to Yanliang for testing that afternoon, and there were also foreign delegations visiting the test flight process, so it would take three days at the earliest before it would be their turn. JHD7.

 The time is not long, so I can afford to wait.

However, Chang Haonan is still a little curious about which model is going to be exported.

  In the 1990s, apart from the clichéd J-7M, the other highlight of China's air force equipment exports was the K8, which was also deeply customized according to the needs of various countries.

This small, straight-wing, subsonic aircraft is very suitable as a low-cost ground attack aircraft. For example, some Southeast Asian countries will require the ability to mount British-made aerial bombs.

Other than that, there are some bits and pieces like Y-12 and Z-9, but these models basically do not involve modification, so there is basically no need to fly to Yanliang.

So before he left, he asked the director of the dispatching office:

“Do you know what model it is? The one that came in the afternoon.”

As soon as the plane lands, basic information such as the model is no secret even to the surrounding wall-crawlers, so Chang Haonan can naturally ask directly.

“A new variant of the J-7 from the 611th Institute, the tentative number is J-7F.”

Hearing this answer, Chang Haonan was stunned for a moment.

He is familiar with the J-7F.

Although he was not directly involved in the overall design of this model, the mandibular air intake that was the core of the improvement plan was the starting point for his journey after his rebirth.

 And the matching work of the inlet and the turbojet 14B engine was completed by Chang Haonan.

 I just didn't expect the efficiency of Factory 132 to be so high. It was only in early April and the prototype had already been built.

Even if this aircraft uses almost no new technology, the speed of building a new aircraft in more than two months is really impressive. The other party probably thought he wanted to contact the other party to jump in line, so he continued to answer:

"However, the foreign delegations coming here are quite big, so it may be difficult to jump in. Besides, your model is not convenient for exposing too much in front of foreigners. They can enter the parking area directly. If they see it, The details are bad.”

 “Oh, that's not what I meant.”

Chang Haonan waved his hand:

“Just asking to see if I can meet anyone I know here.”

“That's probably a mystery. I remember that you seemed to be…”

The director of the dispatching room seemed to suddenly realize something when he said this:

“Hey, I remembered that you are not from the 601 Institute. Why is it that you have a share in the J-H-7 being modified by the 172 Factory?”

Chang Haonan had only been to Yanliang once before, the time when the No. 01 prototype of the J-8C made an emergency landing due to surge, so the dispatch room naturally thought he was from 601.

"Well... I can't be considered as a member of Institute 601. If I have to say it, I should be regarded as some kind of foreign aid..."

Chang Haonan couldn't explain his current somewhat awkward status for a while, so he had to explain vaguely, and then found an excuse to go for lunch and escape.

 That afternoon, the first thing to arrive was a Boeing 737.

　　A group of foreign soldiers wearing blue fur coats walked out.

It seems that Pakistan is the only country that uses sweaters as jackets and hangs various military rank accessories on them.

Then the identity of this foreign user is self-evident.

  After all, in the original timeline, they also purchased a batch of 57 J-7PGs around this time.

The cost of the current J-7F is not much higher, but its combat effectiveness has been significantly improved. For a country with a small area, it can even be used as a small F16, so it is normal for it to be favored.

Shortly after the Boeing 737 landed, an aircraft that Chang Haonan had only seen on the drawings provided by himself or Lu Yuying landed lightly on the runway of Yanliang Airport.

Perhaps because there was a flight show the next day, this prototype marked 02 did not retain the original color of metal or composite materials like most aircraft during the test. The all too common yellow-green camouflage.

What is even more unusual is that the plane flying to Yanliang actually carried two PL8 and two PL11 air-to-air missiles under the wings, which were directly displayed in front of everyone in combat mode.

Generally speaking, prototypes are not so eager to test weapon systems in the early stages of test flight.

 This is obviously a special arrangement when facing customers.

Especially those two PL11 semi-active air-to-air bombs.

On New Year's Eve this year, two J-8Cs shot down a MiG-25, proving the performance of this missile.

 At least not worse than mainstream foreign models such as AIM7 and R27.

Chang Haonan doesn't believe it if the Pakistan Air Force, which almost witnessed the interception with his own eyes, had no idea at all—

 They don't have any aircraft that can hit medium-range bombs yet.

Depending on the customer's choice, the J-7F can be equipped with David's EL/M2032 small pulse Doppler radar, or the KLJ7 radar, a similar product being developed by the 14th Institute of Electrical Engineering.

 Both are capable of locking onto typical fighter-sized targets at a distance of 30-40 kilometers and guiding the PL-11 to attack.

 For many small countries in the 1990s, this was a direct attraction.

Sure enough, Chang Haonan noticed that when the plane slowly passed through the taxiway, the foreign soldiers on the tarmac not far away burst into cheers almost in unison.

 Apparently it works well.
