Chapter 771 Fiery Region
For the Ministry of Foreign Commerce, Gao Zhendong is a treasure. As for why the things designed by Gao Zhendong appear in overseas orders, this is not something that the 12th Machinery Department should be concerned about. The Working Committee and the Ministry of Foreign Commerce have no objections, and they even take charge of it personally, so naturally they have their reasons.
——
At an airport in the northwest, the four engines of a Tu-4 bomber were spinning rapidly, making a huge roar. Although it has been scheduled to be converted into auxiliary special aircraft, before the development of these special aircraft is completed, these Tu-4s are still exerting their last remaining heat, such as today's new ammunition test.
There was only one bomb hung in the belly bomb bay of the bomber.
Judging from the caliber of the bomb, it is 500kg. However, unlike ordinary 500kg high-resistance bombs, this bomb does not look so round, and the cross-section is slightly square. After decades of storage, this cross-section may violate the "rounded trapezoid" patent".
After receiving the takeoff permission from the tower, the bomber pilot pushed the throttle to the maximum. The aircraft made a huge roar and slowly took off into the sky, flying towards the shooting range farther west.
On the shooting range hundreds of kilometers away, dozens of scrap tanks were lined up in a marching formation, full of momentum. If they hadn't just started the engine and the vehicle body didn't move, I'd probably think it was starting. A "head suck (sneak attack)".
On the Tu-4 bomber, in addition to the crew, there were also several testers. They were intently watching the data returned by the bomb's self-checking system.
"The gyroscope is working normally and the inertial navigation system is normal."
"Comparing the data of the inertial navigation system and the aircraft navigation system, the error is within the acceptable range."
"The spreader is in normal condition."
One piece of data and one voice report from the tester The side reports came over and gathered at Mr. Zhang of Chunlei Factory.
Anyway, there is a computer, and the speed is not slow. The comrades who designed the spreader simply designed a status monitoring system to transmit the status of the spreader to the test instrument in real time, which greatly simplified and facilitated After testing, this system can also greatly reduce the maintenance workload of inventory ammunition in actual use.
“Mr. Zhang, I didn’t expect that our spreader can also use inertial navigation. Although the accuracy is not very high, it is enough.”
Mr. Zhang smiled and said: "Thanks to Mr. Gao's microcontroller. With it, the space of the original DJS-60DJ was saved at once, and there was also extra space and cost to install a simple inertial navigation system. System.”
“I didn’t expect it to be so simple. A single submunition bomb can actually be guided. "
Different from the original plan of setting the direction and range and then setting the timing fuse, they used a lot of advanced technology on this bomb. Now this Compared with when we first planned it, we have made a lot of progress.
At this time, the captain's voice came: "We are about to enter the release area."
Mr. Zhang looked at the data on the mission navigation display and signaled to the comrades: "Set the target data , prepare to drop the bomb.”
On the mission navigation display, a small light spot representing the Tu-4 bomber is moving towards a green circle. Once it enters this circle, it means that it has reached the bombing area.
Unlike horizontal bombing and dive bombing, the requirements for the bombing area of the long-range dispenser are not very strict. As long as the target position is set, it is OK to release the bomb earlier or later. The simple inertial navigation system will naturally adjust the flight trajectory of the spreader based on the target data.
It can be said that for a dispenser with inertial navigation, the time window for bomb delivery is extremely large.
"The target data setting is completed." For the spreader, instead of calling it a target, it is better to be called a spreading point. You only need to fly to the appropriate position and height according to the set data, and then explode Just scatter the bullets.
"The scheduled bomb delivery height has been reached." For a spreader that has no power and relies on gliding, in principle, the higher the bomb release height, the better.
Mr. Zhang watched the plane enter the scheduled bomb drop area and calmly ordered: "Drop the bomb!"
At this time, the belly bomb bay door had already been opened.
As the bomber pressed the button, the dispenser fell out from the belly of the aircraft. The two bomb wings unfolded and flew towards the target area. It still had a way to go, and it was still almost there from the target area. 60 kilometers, for a spreader that does not glide very fast, it takes more than ten minutes to fly.
“The bombing is completed and the flight trajectory of the dispenser is normal.”
The Tu-4, which had completed the bombing, did not rush back, but also flew towards the target area. Their current The task is to keep up with the spreader. The effective distance of the specially installed telemetry transmission station on the spreader is limited. If you want to obtain real-time test data, Figure-4 must follow this thing.
The gliding speed of the spreader is very slow, which has reached a point of difficulty for the Tu-4 bomber. The aircraft cannot fly too fast, and flying very slowly is also a huge challenge.
“It’s a good airplane, but it can’t fly too slow.” This is what the island’s pilots said about the famous widow-maker and flying coffin F-104 Star fighter. A few of those were shot down, but a huge number fell down. Looking at the crash list published on the island, even the numbers are consecutive. But in fact, this evaluation applies to all aircraft.
Fortunately, the crew of Tu-4 has superb driving skills. Although it still flies faster than the spreader, it still basically maintains the reception of telemetry signals, and only occasionally needs to turn back and hover.
"Flight attitude is normal."
"Speed is normal." "Descent rate is normal."
Descent rate is a very important indicator. The overall trend of gliding aircraft is to decline, and this descent rate is not only related to the range, but also related to the intended dispersion height. Ammunition, the requirements for this parameter are different.
When the spreader is flying in the air, it will encounter changes in air density or severe atmospheric activity, which will interfere with the descent rate. At this time, the guidance system needs to take action.
“There is an updraft, and the flight altitude increases.” This situation is translated as “being blown up by the wind.” In fact, it will affect this, not only the updraft, but also the wind with a relatively high speed. In the end, In extreme cases, there is even downwash.
"Guidance system descent rate compensation intervention takes effect!"
This is a test under actual combat conditions. You will encounter any situation, but fortunately the guidance and flight control system work very effectively.
At the shooting range at this time, far away from the rows of tanks, there was an observation post, which was also full of testers. The observation post was obviously specially reinforced, with a steel plate installed on the top. There are many thick layers of sandbags on top of the steel plate.
No way, this kind of palm technique falling from the sky is really unreasonable, and the strike area is very wide.
On the radio station inside the observation station, a voice with a little "rustling" sound sounded: "The spreader is about to arrive at the intended target."
At this time, the personnel at the observation station had already heard it The roar of the Tu-4 flight. In order to keep up with the test bombs, they actively lowered their altitude. If the altitude was too high, the radio signals would be able to be received, but they would not be able to clearly see the dispersion situation.
At this time, Mr. Zhang was in the navigator cabin of Figure 4, looking down with a telescope. Although the spreader was not easy to find, the row of tanks on the ground was very conspicuous. Just look at them.
This work was compiled and uploaded by Liujiu Book Bar~~
The comrades at the observation station held a telescope and looked to the east. They could see an airplane, but no disperser was found. The shadow is really a bit small.
The comrades searched hard, and finally someone shouted: "I saw it, I saw it, it's almost there!"
Not long after these words were shouted, several pieces of thin film suddenly flew into the air. The thin thing, that is, the shell of the spreader was thrown away, and then I saw small black dots flying away from the spreader, and umbrella flowers bloomed in the sky above the tank group. It was really shocking. nice.
It looks good, but it hides a strong murderous intent.
Looking from Figure 4, the black and white umbrella flowers in the sky turned into red flowers one after another, and then the tanks on the ground began to explode and catch fire, sending out billowing smoke.
If the picture seen in Figure 4 is not direct enough because it is too high, then the comrades at the ground observation station have a different experience.
Looking from the bottom up, fire dragons descended from the sky and pounced on the tanks, almost hitting every target. These ghosts in the sky would even turn a blind eye to the tanks that were burning with raging fire, looking for them. Hit intact.
For a moment, the shooting range in front was an underworld scene of smoke and fire.
Some comrades here have also participated in the mortar terminal sensitivity test, but those few tanks are not as shocking as today's large swarm.
A few tanks were on fire, it was just drizzle, but in front of them was an entire tank battalion! This has an extremely huge impact on everyone!
Our current tank company is a "ten-car company". A tank company has ten tanks, and a tank battalion has thirty tanks, not counting other vehicles.
The dispenser in the air contained a total of 45 terminally sensitive bombs.
There are thirty tanks in this battalion. If it were not for the Kursk battle between Lao Maozi and Hans, under normal circumstances they would need to be attacked and pulled back and forth many times before they would be exhausted. All.
But today, under the blow of a disperser dropped from 60 kilometers away, the tank battalion was wiped out almost instantly. There was thick smoke and fire everywhere, and it burned cracklingly.
Quantitative change to a certain extent means qualitative change, and the same is true for the impact on people's psychology. The comrades in the armored force who participated in the test looked at each other.
Terrible! Very scary! This is not cowardice, but an objective evaluation.
What? Is this thing ours? That’s okay!
A few hours later, a report and two photos were placed on the desk of the leader of the National Defense Work Committee.
A photo was taken from Tu-4. Viewed from a height, most of the thirty tanks were on fire, and the few lucky ones who escaped seemed very lonely inside.
The other photo was taken from the observation station. At a glance, the photo is full of thick smoke slanting into the blue sky, and nothing else can be seen.
