Rebirth 1975: Tore up the call-back order at the beginning

In the next few days, everyone in the entire research institute focused on the radar test.

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 effect is very good.

Not only did the various data basically reach the target value set by Zhou Yang before, but even several items were much stronger than the designed parameters.

This is like 90 points are considered excellent, you directly scored 100 points in the test.

It can be said that the entire extension testing stage has been full of surprises, and everyone including Nie Nansun, Niu Weitong, and Guo Yamin are full of enthusiasm.

Therefore, after the end of the extension test, Mr. Nie and others, after careful research, immediately ordered the No. [-] project department to conduct a joint test of the whole machine immediately, and completed all the test tasks in one go, and confirmed this radar.

Radar testing is a delicate task. It does not mean that the radar is successful if the performance of each functional extension meets the standard.

No, even if the above-mentioned functions are all tested, more stringent tests are required.

In many cases, everything is normal when the radar extension is tested, but after the whole machine is installed, there will be many problems when testing again. mean).

So the extension test is just the beginning, and the real test of the radar performance is the whole machine joint test.

And different from the extension test, the whole machine joint test is more complicated, and the required environment is not only indoors.

For example, when testing the active emission and detection performance of the radar, there must be corresponding active targets. In the case of no local airport, sometimes it is even necessary to take the radar to other places for testing.

Of course, this is a conditional choice.

In the absence of conditions, you can only create targets to be searched and detected by yourself.

All in all, the joint test of the whole machine is the real gate of hell, 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 procrastinate.

The reason is also simple. It is already late August, and the domestic situation will soon undergo drastic changes.

When the situation is chaotic and no one cares about others, their side will inevitably be affected, and there may not be such conditions when thinking about testing.

Once the opportunity is missed, it may not be three or two months, or even one or two years.

So taking advantage of the fact that the situation is still stable and not many people are paying attention to their side, let's get things done quickly.

Immediately, he ordered the comrades in the test team to assemble all the electronic components of the radar immediately.

At the same time, Zhou Yang asked Carpenter Zhao from the village to specially build a model of the nose of the F14 fighter jet that defended against the Bandit Eagle, preparing to set up the radar.

The reason why the F14 is used instead of domestically produced fighters is not because they worship foreigners, but because domestic fighters are all Soviet-style pointed fighters.

Those who have seen the J-[-] and J-[-] know that the noses of these types of fighters are very thin, and pulse Doppler radar cannot be installed at all.

Therefore, we can only make a model in the style of the Jaeger's round-headed aircraft.

Master Zhao’s craftsmanship is undeniable. After Zhou Yang simply drew a picture of the nose, he took three days to make the model of the F14’s nose, and the similarity is very similar. high.

Not to mention other people at this level, even the well-informed Mr. Nie was amazed.

After the wooden model of the airplane was completed, Zhou Yang immediately asked people 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 8, the atmosphere at Xipo Institute was highly tense.

Today, in addition to all the researchers gathering to participate in the joint test of the whole machine, all the security forces are also dispatched.

Not only did the entire research institute be surrounded by water, the guard post was even placed outside the village.

At the same time, at the request of Mr. Nie, all the militia guards in Babaoliang Village also assembled to patrol around the clock in and out of the village.

It is required that all roads entering and exiting the village must be strictly sealed off during the test period of the joint test of the whole machine, and Babaoliang Village is not allowed to receive anyone during this period.

No way, the radar test is afraid of leakage and interference!

Any error may cause inaccurate test results and affect subsequent progress and evaluation.

At nine o'clock, the weather was fine and the weather conditions were right.

The researchers removed the tarpaulin from the wooden model and asked for a test.

Then under Zhou Yang's order, the test team first conducted a passive detection, interception and tracking test.

The effect is very good, no incongruity was found, and the result is as amazing as the previous extension test.

Then the main event came, Zhou Yang asked the test team to test the performance of the radar's active launch and detection and tracking, which is the most important function of the radar.

In order to create an environment where the radar can actively launch and detect and track, Zhou Yang proposed a balloon test.

It is to use one or two large weather balloons, filled with hydrogen, with an aluminum corner reflector, pulled into the sky with a string, and the corner reflector becomes a stationary target in the air.

If the radar can detect prohibited targets in the air, it means that the detection capability is fine.

Soon, the comrades who released the balloons got ready, and under the signal of Chen Shanhe, they slowly released the hydrogen balloons into the air.

The moment the hydrogen balloon flew into the sky, there was a quick response on the radar screen. 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 the success of the test, the entire research institute erupted into applause.

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 a step closer to the real finalized production.

After the cheers, Zhou Yang asked the researchers of the test team to do three ground-to-air experiments in which the balloons were released, and the number of balloons increased from two to 24. As a result, the radar was working normally.

After confirming that there was no problem, Mr. Nie immediately announced that everyone in the entire institute would have extra meals in the evening.

At the same time, Mr. Nie made another major decision, which is to detect dynamic targets next.

He planned to mobilize a helicopter from the Beijing Military Region to participate in the test to see how powerful the radar was.

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 tests.

However, most of such tests are tests of the actual combat capability and life of the radar, and do not affect the overall design of the radar.

After hearing Lao Nie's decision, Zhou Yang immediately put forward his own idea, one helicopter is too little, so a few more.

In addition, there is no need to do any rehearsal, and it is too troublesome to start the test after the helicopter arrives.

Let's follow the normal actual combat situation to catch a mouse once!

When to come over there, roughly tell the time, and the rest will come from which direction, needless to say how much, and then look at the performance of the radar.

After hearing Zhou Yang's plan, Mr. Nie was also shocked by Zhou Yang's bold idea.

You must know that the radar they designed is still in the testing stage, and a considerable part of the functions have not been tested, so Zhou Yang will directly drag it to the battlefield.

I have to say that this kid is really bold!

At the same time, Nie Nansun could tell that Zhou Yang was quite confident in this radar.

Now that he had said so, Nie Nansun would naturally not refuse, and immediately made arrangements.

Soon, the shocking scene in the history of radar testing appeared!
