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. Even if the opponent shuts down and runs away, a near miss is enough to destroy the entire radar.
He 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 produce. 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 the inherent advantage of gravity potential energy, and they do not need to be as fast as air-to-air missiles, they can replace the slow-burning propellant, and the range should be much better than the 30km of Thunderbolt 11.
What’s more important is that it does not involve too many new technologies and can be produced and equipped with troops in a very short time.
First let the aviation force have something to use, and then get familiar with the tactics.
Although it is said that we would rather have people wait for equipment than let equipment wait for people, the actual situation is that if you don’t even have the most basic abilities, void practice is likely to go in the wrong direction. It is better not to practice at all. .
I just don’t know if anyone is promoting this anti-radiation model over there 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 calling them, so he simply entrusted them and returned. Guo Lin from Jinling went to inquire.
......
As time goes by, this electric warfare 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 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.
Relevant data recording and collection work, as well as flight safety assurance, require assistance from the Flight Test Institute.
If you catch up with the crowd, you 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 to visit the test flight process, so it would take three days at the earliest. Only then will it be their turn to destroy the JHD-7.
It doesn’t take long, so I can afford to wait.
However, Chang Haonan is still a little curious about which model is ready for export.
In addition to the clichéd J-7M, the other highlight of the Chinese Air Force’s equipment exports in the 1990s 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 addition of 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 room:
"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 not a secret even to the surrounding wall-crawlers. Chang Haonan can naturally Just ask.
"The 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.
The J-7F is familiar to him.
Although he was not directly involved in the overall design of this model, the mandibular air intake as 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 just 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 that he wanted to contact the other party to jump in the queue, so he continued to answer:
"But the foreign delegations coming here are quite big, so it may be a bit difficult to jump in the queue. Besides, your model is not very convenient. It’s too much exposure in front of foreigners. They can enter the parking area directly. It would be bad if they see the details.”
“Oh, that’s not what I meant.”
Chang Haonan waved his hand:
“Just asking to see if I can meet someone I know here.”
"That's probably a mystery. I remember you seem to be..."
When the director of the dispatching room said this, he seemed to suddenly realize something:
"Hey, I remember you are not from the 601 Institute, why is it that now you have a share in the JH-7 modification in the 172 Factory?"
< br>Chang Haonan had only been to Yan Liang 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 situation for a while. Being in a somewhat awkward status, I had no choice but 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.
Not long 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 will be 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, but was painted with The yellow-green camouflage is not very common in China.
What is even more unusual is that the plane that flew to Yanliang actually carried two PL8 and two PL11 air-to-air missiles under the wings, which were directly mounted in combat form. In front of everyone.
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 it is not worse than mainstream foreign models such as AIM7 and R27.
To say that the Pakistan Air Force, which almost witnessed this interception, had no idea at all, Chang Haonan did not believe it——
They don't have any aircraft that can hit medium-range bombs yet.
According to the customer's choice, the J-7F can be equipped with the EL/M2032 small pulse Doppler radar of David Guo, or the KLJ7 radar, a similar product being developed by the 14th Institute of Electrical Engineering.
Both can lock onto typical fighter-sized targets at a distance of 30-40 kilometers and guide the Thunderbolt 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.
