In the cabin, Zhou Yang and others fastened their seat belts and gradually raised their altitude amidst the loud noise of the plane.
As the altitude of the plane increased, Zhou Yang clearly felt the vibration on the plane.
This is because the weight of the aircraft is too large and the stability of the aircraft is not high.
Although this level of buffeting is indeed within the range that the pilot can bear and does not have a great impact on the control of the aircraft, it will have a greater impact on the staff who debug the radar equipment later.
Once on the battlefield, the huge noise coupled with such frequent buffeting will inevitably affect the normal work of the radar operator.
At that moment, Zhou Yang immediately recorded this issue.
At the same time, Zhou Yang felt that the power of Air Police No. 1 was not as strong as expected, and the aircraft seemed to be struggling a little while climbing.
This can also be reflected from the huge roar of the aircraft engine.
In fact, Zhou Yang thought of this problem when he came over 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 cover also changed the lines of the aircraft, which greatly The ground increases flight resistance.
The Figure 4 bomber is equipped with four АЩ-73ТК engines, and its power is definitely not enough.
However, judging from the current shape of the aircraft, it should have been replaced with a domestically produced turboprop-6 engine.
But now, the motivation is still insufficient.
Soon, the plane climbed into the stratosphere and the turbulence subsided.
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 behind also acted quickly and turned on the 843 radar on the aircraft.
The radar cabin is located in the middle section of the Tu-4 bomber. The original bomb bay is converted into a sealed cabin. This is also where the radar operator works.
However, Zhou Yang carefully checked the layout of the radar cabin and found that the layout of Air Police No. 1 was very backward. The sub-systems only included the warning radar system, data processing system, data display and control system, identification of friend or foe, 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. 1 uses radio stations in the UHF and VHF bands to conduct air-to-ground and air-to-air communications respectively. In terms of radar data processing and information transmission, it lacks a practical human-machine interface and has to compromise by relying on manual plotting and voice communication for air-to-air communications. Affection.
Such backward data processing and communication methods will inevitably greatly affect the combat capabilities of early warning aircraft in actual combat.
Moreover, the current data transmission equipment is modified with radio telex machines, and the air condition display in the airspace is mainly represented by drawing boards. Therefore, the operator and controller must keep an eye on the display, otherwise they are likely to miss the air condition.
All in all, the technology of Air Police No. 1 is really not that good, and the design concept is very different from the world's early warning aircraft technology.
Just when Zhou Yang was recording all the problems he had discovered, a bright spot suddenly appeared on the radar screen, and then the operator loudly said: "Report, enemy fighter planes were found, heading southeast, distance 280 kilometers!"
Immediately afterwards, the scientific researchers in charge of communications immediately reported the "enemy situation" to the ground command center for verification.
Soon, the ground command center responded and the intelligence was accurate.
This means that Kongjing-1's detection of medium- and high-altitude targets is still very good, and it can detect enemy aircraft targets 280 kilometers away, which has reached the advanced level of foreign countries.
The test was successful again, which made the researchers on the plane a little excited.
But at this moment, Zhou Yang suddenly said: "Send a message to the ground and let the target aircraft fly at low altitude!"
"yes!"
Soon, the correspondent transmitted Zhou Yang's order back to the ground.
Less than three minutes later, the bright spot on the radar suddenly flashed, and then disappeared from the display.
Air Police No. 1 uses multiple radar P-type displays, in addition to two A-type displays. After discovering that the target disappeared, the operator immediately searched for it on several other displays.
However, there is indeed no signal source from the enemy aircraft.
Everyone immediately adjusted the detection angle to reduce the blind spot.
Soon, the target source appears on the monitor again.
Seeing this, everyone relaxed a little.
But soon, the target signal disappeared again.
In this way, the scientific researchers on Air Police No. 1 constantly adjusted the detection angle of the radar, and started a cat-and-mouse game with the "enemy aircraft" on the opposite side.
However, the signal source of the enemy aircraft has always been in an intermittent and looming state.
Although it did not completely lose track of the enemy aircraft, it also illustrates a problem, that is, the effectiveness of Air Police No. 1 in detecting low-altitude flying targets is worrying.
For an early warning aircraft that focuses on early warning detection, this flaw can be said to be fatal.
Zhou Yang also knew that the reason for this situation was directly related to the performance of the airborne radar.
This also reminded Zhou Yang of the reason why the "Air Police No. 1" project was cancelled!
There are two important reasons for the cancellation of the Air Police No. 1 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, it retains the original structure after all, and there may be potential risks 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 the time, the "Kongjing-1" early warning aircraft radar had too strong ground clutter when detecting low-altitude targets from above land, and the detection performance was relatively poor. generally.
To solve this problem, it is necessary to master the emerging pulse Doppler technology. At that time, the early warning aircraft of the Thief Eagle and other countries had begun to break through this technology, so the "Air Police No. 1" project was also cancelled.
Thinking of this, Zhou Yang felt that he should do something.
He can't control airplanes, but he can control radar!
Moreover, their Babaoliang Research Institute has trained a large number of scientific researchers who have mastered pulse Doppler technology. As long as there is support from above, plus the radar design drawings in his mind, he wants to create a radar for early warning aircraft. radar, it shouldn’t be too difficult.
Of course, if this matter is to be accomplished, the premise is to obtain the support of the superior department.
After all, this is not as simple as artillery reconnaissance radar. It only needs to modify the 370 and 372 radars.
The radar used by early warning aircraft is much more complex than this, and it cannot be too large and must be miniaturized.
The funds required for the entire research and development process are not a small amount, and it is simply not possible to rely on the remaining funds 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. 1, which is equivalent to openly provoking others.
If the higher-ups don't say anything, 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 an airborne radar for an early warning aircraft.
There is no way, the early warning aircraft is really important to any country, and it is not an exaggeration to say that it is the most important weapon of the country.
If he has offended someone because of his research on advanced airborne radar, he will admit it!
While Zhou Yang was deep in thought, after receiving a report from the staff on "Air Police No. 1", the ground command center also realized the seriousness of the problem and immediately ordered the aircraft to return and suspend the test!
Then, under the control of the pilot, the plane returned towards the airport and slowly landed on the runway ten minutes later!
