In the next few days, everyone in the entire institute focused on radar testing.
In just one week, the extension test that originally took one to three months was successfully completed.
As far as the results of the extension joint test are concerned, the results are very good.
Not only did each data basically reach the target value set by Zhou Yang before, but several of them were even much stronger than the designed parameters.
This is like 90 points is considered excellent, and you directly scored 100 points.
It can be said that the entire extension testing phase has been full of surprises. Everyone, including Nie Nansun, Niu Weitong, and Guo Yamin, are all very motivated.
Therefore, after the extension test, Mr. Nie and others, after careful study, immediately ordered the No. 0 Project Department to immediately conduct a joint test of the entire machine, complete all test tasks in one go, and confirm this radar.
Radar testing is a delicate job. It does not mean that the performance of each functional extension reaches the standard, the radar is successful.
No, even if the above-mentioned functions have been tested, more stringent tests must be carried out.
Many times when the radar extension is tested, everything is normal, but after the whole machine is installed, many problems will appear when testing again. Sometimes the whole machine is normal after several times of installation and removal (that is, after installation, disassembly, and reinstallation) mean).
Therefore, the extension test is just the beginning. The real test of radar performance is the joint test of the entire machine.
And unlike the extension test, the whole machine joint test is more complicated and requires an environment not just indoors.
For example, when testing the active emission and detection performance of radar, there must be corresponding moving targets. When there is no local airport, sometimes it is even necessary to take the radar to other places for testing.
Of course, this is a conditional choice.
If there are no conditions, then you can only create the target to be searched and detected by yourself.
All in all, the joint test of the entire machine is the real hurdle, and many radars are stuck at this step.
Zhou Yang naturally had no objection to Mr. Nie's request. Firstly, he was very confident in this radar, and secondly, he didn't want to delay it.
The reason is also simple. It is already late August, and the domestic situation will soon change dramatically.
When the situation becomes chaotic next, no one will be able to care about anyone else, and their side will inevitably be affected. If they want to test it again, they may not have such conditions.
Once the opportunity is missed, it may not be three or two months, or even one or two years.
So while the situation is still relatively stable and not many people are paying attention to them, they quickly get things done.
He immediately ordered the comrades in the test team to assemble all the electronic components of the radar immediately.
At the same time, Zhou Yang found Carpenter Zhao from the village and asked him to specially build a model of the nose of the F14 fighter jet of China, and prepare to set up a radar.
The reason why the F14 is used instead of domestically produced fighters is not because of admiration for foreigners, but because domestic fighters are all imitating Soviet-style pointed-nosed fighters.
Anyone who has seen the J-5 and J-6 will know that the noses of these types of fighters are extremely thin and cannot be equipped with pulse Doppler radars.
Therefore, we can only make a model based on the style of the Thief Eagle's large round-nosed aircraft.
Master Zhao’s craftsmanship is truly incredible. After Zhou Yang simply drew a pattern of the nose, it took him three days to make the model of the F14’s nose, and the similarity was very similar. high.
Not to mention other people, even the well-informed Mr. Nie was amazed at this level.
After the wooden model of the aircraft was completed, Zhou Yang immediately asked someone to install the pulse Doppler radar on a wooden model.
Everything is ready and the whole machine can be tested at any time.
........
On the morning of August 21, the atmosphere at Xipo Research Institute was highly tense.
Today, in addition to all the researchers gathered to participate in the joint test of the complete machine, all the security forces were also dispatched.
Not only was the entire research institute surrounded, but security posts were even placed outside the village.
At the same time, at the request of Mr. Nie, the militia guards of Babaoliang Village also gathered together to patrol in and outside the village around the clock.
It is required that during the test period of the complete machine joint test, all roads in and out of the village must be strictly blocked, and Babaoliang Village is not allowed to receive anyone during this period.
There is no way, radar testing is afraid of leaks and interference!
Any error at any point may cause inaccurate test results and affect subsequent progress and evaluation.
At nine o'clock, the weather was clear and the weather conditions were suitable.
The researchers lifted the tarps over the wooden models and asked for testing.
Subsequently, under Zhou Yang's order, the test team first conducted passive detection, interception and tracking tests.
The effect was very good, and no incongruity was found. The results were as amazing as the previous extension test.
Then came the highlight. Zhou Yang asked the test team to test the radar's active emission and detection and tracking performance. This is the most important function of the radar.
In order to create an environment where radar can actively transmit and detect and track, Zhou Yang proposed a balloon release test.
Just use one or two large weather balloons, fill them with hydrogen, bring an aluminum corner reflector, pull it with a string and put it into the sky. The corner reflector becomes a stationary target in the sky.
If the radar can detect prohibited targets in the air, it means there is no problem with its detection capabilities.
Soon, the comrade who released the balloon was ready, and at Chen Shanhe's signal, he slowly released the hydrogen balloon into the air.
The moment the hydrogen balloon flew into the sky, the radar's display screen reacted quickly. The target signal was obvious and clear, and the response speed was very fast.
When the scientific researcher in charge of the test loudly reported that the test was successful, the entire institute burst into cheers.
The significance of the joint test of the whole machine is extraordinary. Once the joint test of the whole machine is successful, it will be one step closer to the actual finalized production.
After cheering, Zhou Yang asked the scientific researchers of the test team to conduct three ground-to-air tests of releasing balloons, and the number of balloons increased from two to 24. As a result, the radar worked normally.
After confirming that there was no problem, Mr. Nie immediately announced that everyone in the institute would have a extra meal that night.
At the same time, Mr. Nie made another important decision, which was to detect dynamic targets next.
He plans to mobilize a helicopter from the Beijing Military Region to participate in the test to see how powerful this radar is.
If it can pass the detection of dynamic targets, then this radar has initially passed the detection, and the rest is high temperature and low temperature testing.
However, most of such tests are tests of the radar's actual combat capabilities and lifespan, and do not affect the overall design of the radar.
After hearing Mr. Nie's decision, Zhou Yang immediately put forward his own idea. One helicopter was too few, so let's get a few more.
In addition, there is no need to do any rehearsal, and there is no need to start the test after the helicopter arrives, which is too troublesome.
Let's follow the normal actual combat situation and try to catch the mouse!
Let’s give a rough estimate of when we’ll come over there. It doesn’t matter which direction we’ll come from and how many times we’ll come from. We’ll see how the radar behaves when the time comes.
After hearing Zhou Yang's plan, Mr. Nie was also frightened by Zhou Yang's bold idea.
Knowing that the radar they designed is still in the testing stage, and quite a few functions have not yet been tested, Zhou Yang is going to take it to the battlefield.
I have to say that this guy is really brave!
At the same time, Nie Nansun could also see that Zhou Yang was quite confident in this radar.
Since he said so, Nie Nansun naturally would not refuse and immediately made arrangements.
Soon, a shocking scene in the history of radar testing appeared!
