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

In the cabin, Zhou Yang and others wore seat belts, and gradually raised the altitude amidst the loud noise of the plane.

As the height of the plane rose, Zhou Yang could clearly feel the buffeting on the plane.

This is due to the high weight of the aircraft and the low stability of the aircraft.

Although this level of chattering is indeed within the range that the pilot can bear, it does not have a great impact on the control of the aircraft, but it has a greater impact on the staff who adjust the radar equipment later.

Once it is on the battlefield, the huge noise plus such frequent chattering will inevitably affect the normal work of the radar operator.

At that moment, Zhou Yang immediately recorded the question.

At the same time, Zhou Yang felt that the power of Air Police One was not as strong as expected, and the plane seemed to be struggling a bit when it was climbing.

This can also be reflected from the huge roar of the aircraft engine.

In fact, Zhou Yang thought of this question when he came here in the morning. After all, the 7-meter-diameter radome carried on the fuselage greatly increased the weight of the aircraft. In addition, such a large radome also changed the lines of the aircraft. The earth increases flight resistance.

The Figure 73 bomber is equipped with four aЩ-[-]tk engines, and its power must be insufficient.

However, judging from the current shape of the aircraft, it should have been replaced with a domestically produced turboprop-6 engine.

But looking at it now, the motivation is still insufficient.

Soon, the plane climbed into the stratosphere, and the turbulence weakened.

At this time, the test pilot immediately reported the situation to the ground tower.

At the same time, the staff in the radar operation cabin at the back also acted quickly and turned on the 843 radar on the plane.

The radar cabin is located in the middle section of the Tu-4 bomber, that is, the original bomb bay is converted into a sealed cabin, and this is also the place where the radar operator works.

However, Zhou Yang took a closer look at the layout of the radar cabin, and found that the layout of Air Police No. [-] was very backward. The subsystems only included the warning radar system, data processing system, data display and control system, identification friend or foe system, communication and data transmission system, Navigation and guidance systems, electronic countermeasures systems.

These are nothing, the most important thing is that communication and information processing are very backward.

Air Police No. [-] uses UHF and VHF band radio stations to serve as air-to-ground and air-to-air communications respectively. In the link of radar data processing and information transmission, it lacks a practical man-machine interface, and has to rely on manual plotting and voice communication to transmit air-to-air communications. Affection.

Such backward data processing and communication methods will inevitably greatly affect the combat capability of early warning aircraft in actual combat.

Moreover, the current data transmission equipment is modified with a radio transmission machine, and the air condition display in the airspace is mainly represented by a drawing board, so the operators and controllers must keep an eye on the display, otherwise they may miss the air condition.

All in all, the technology of Air Police One is really not good, and the design concept is very different from the world's early warning aircraft technology.

And just when Zhou Yang recorded all the problems he found, a bright spot suddenly appeared on the radar screen, and then the operator said loudly: "Report, an enemy fighter plane was found, its orientation is southeast, and the distance is 280 kilometers!"

Immediately afterwards, the scientific research personnel in charge of communication immediately reported the "enemy situation" to the ground command center for verification.

Soon, the ground command center responded, and the information was accurate.

This means that the detection of mid- and high-altitude targets by Air Police No. 280 is still very good, and it can detect enemy aircraft targets at a distance of [-] kilometers, which has reached the advanced level of foreign countries.

The successful test again made the scientific researchers on the plane a little excited.

But at this moment, Zhou Yang suddenly said: "Send a report to the ground and let the target plane fly at a low altitude!"

"Yes!"

Soon, the correspondent transmitted Zhou Yang's order back to the ground.

After less than 3 minutes, the bright spot on the radar suddenly flickered, and then disappeared on the display.

Air Police No. 2 uses multiple radar P-type displays, in addition to two A-type displays. After finding the target disappeared, the operator immediately searched for it on several other displays.

However, there is indeed no signal source of enemy aircraft above.

Everyone immediately adjusted the detection angle to reduce the blind spot.

Soon, the target signal source appears on the display again.

Seeing this, everyone was slightly relieved.

But soon, the target signal disappeared again.

In this way, the scientific research personnel on Air Police No. [-] constantly adjusted the detection angle of the radar, and started a cat-and-mouse game with the "enemy plane" on the opposite side.

However, the signal source of the enemy plane has always been intermittently looming.

Although it didn't completely lose the enemy plane, it also showed a problem, that is, when Air Police No. [-] detected low-altitude flying targets, its effect was worrying.

For an early warning aircraft that focuses on early warning detection, the defect can be said to be fatal.

Zhou Yang also knew that the reason for this situation was mainly directly related to the performance of the airborne radar.

This also reminded Zhou Yang of the reason why the "Air Police One" project was discontinued!

There are two important reasons for the discontinuation of the Air Police No. [-] project. The first is that the aircraft platform that Zhou Yang complained about before is too old.

Although the Tu-4 aircraft has been improved and strengthened, after all, the original structure is retained, and there may be hidden dangers of platform failure in terms of strength.

The second reason is that the radar is not up to standard. Due to the failure to break through the emerging pulse Doppler technology at that time, the early warning aircraft radar of "KongJing No. [-]" has too strong ground clutter when detecting low-altitude targets from the sky over land, and its detection performance is relatively low. generally.

To solve this problem, it is necessary to master the emerging pulse Doppler technology. At that time, early warning aircraft of countries such as the Javelin Eagle had already begun to break through this technology, so the "King Jing No. [-]" project was discontinued.

Thinking of these, Zhou Yang felt that he should do something.

He can't control the plane, but he can do the radar!

Moreover, their Babaoliang Research Institute has trained a large number of scientific researchers who have mastered pulse Doppler technology. As long as they have the support from the above, coupled with the radar design drawings in his mind, they want to come up with an early warning aircraft. Radar, it shouldn't be too difficult.

Of course, if this matter wants to be done, the premise is to get the support of the higher authorities.

After all, this is not as simple as the artillery reconnaissance radar. It only needs to modify the 370 and 372 radars.

The radar used by the early warning aircraft is much more complex than this, and the volume should not be too large, it must be miniaturized.

In the entire research and development process, the required funds are not a small amount, and it is impossible to rely on the little funds left in the institute.

More importantly, if they study the airborne radar of the early warning aircraft, it will inevitably affect the current research and development unit of Air Police No. [-], which is equivalent to provoking others.

If the higher-ups don't speak, this matter really can't be done!

But after thinking about it for a while, Zhou Yang decided to go back and have a good chat with Mr. Nie. He wanted to develop the airborne radar of the early warning aircraft.

There is no way, the early warning aircraft is so important to any country, it is not an exaggeration to say that it is the most important weapon of the country.

If he offended some people because of researching advanced airborne radar, he must admit it!

While Zhou Yang was in deep thought, after receiving the report from the staff on "Air Police One", the ground command center also realized the seriousness of the problem, and immediately ordered the plane to return and suspend the test!

Then, under the pilot's operation, the plane headed back towards the airport, and slowly landed on the runway after ten minutes!
