Chapter 1320 The balance mechanism of Earth OL
As Han Xiangjie's order was issued, the cover plate of the light green barrel in the No. 8 launch tube made a "bang" sound, and then quickly bounced upward.
This is a step that did not exist in training in the past.
Most submarine-launched missiles fired from launch tubes rather than torpedo tubes are installed directly in the tube, filled with water before ignition, and then ignited underwater.
Even some dry-launch models will use high-pressure gas or projectiles to directly break the second-layer cover.
After all, the radar components this time still need to be recycled, so the container design is quite sophisticated.
A few minutes later, amidst the buzzing of the hydraulic power-assisted equipment, a cylindrical device like an umbrella skeleton rose from below, and then unfolded into a rectangular grid antenna with a size of 2.5 meters * 8 meters. It starts to rotate slowly at a speed of 3r/min.
"Report to captain, the antenna array is powered on successfully."
In the boat's internal communicator, the chief engineer in the forward auxiliary engine room began to report the situation:
"The generator set is working at high load, but the operating parameters and noise are still stable..."
Due to the hasty modification time, this radar was not fully integrated into the Long March 9 command system. The technicians only had time to separate a line from the signal system so that everyone in the command module could use the multi-function display and The search results can be seen on the electronic chart table, but the control operations still need to be completed under the rear missile bay. As for the power, it is also directly supplied from the front auxiliary engine room.
"Pay close attention to the operation of the equipment. If there is any fluctuation, report it to me immediately."
Han Xiangjie ordered.
"Received."
A brief response came from the other side.
During the previous training process, he discovered that the power consumption of this radar far exceeded his estimate.
Although the nuclear reactor can provide nearly unlimited energy on paper, most of it will be transmitted to the main shaft through the gearbox as propulsion power. What's more, the front and auxiliary engine rooms operate completely independently, so the power supply situation is not what many people imagine. So abundant.
After successfully completing this step, the following task process has little to do with the crew——
There are basically no professional radar posts on submarines, so a dozen comrades recruited from the surface ship force and the Electrical Engineering Group are responsible for operating the equipment.
As the captain, Han Xiangjie also had time to consider other things.
"I said, Lao Fan, now that power management technology has improved, is it possible for future nuclear submarines to return to the way 09I and 09II did, first using nuclear reactors to generate electricity, and then distributing power to power and equipment separately?"
Taking advantage of the time spent debugging the radar, Han Xiangjie asked Fan Zhaohui.
Early models of Huaxia nuclear submarines used a steam turbine-electric motor propulsion scheme, and even had a bit of an integrated power system.
But just like the electric-driven tanks in the early years, it sounded quite sci-fi, but in actual use it was quite poor in terms of performance and reliability. Therefore, in the 09III and 09IV, it still returned to the traditional technical route.
However, after today's experience, Han Xiangjie suddenly remembered the few advantages of the old model.
After hearing this, Fan Zhaohui pondered for a moment, and finally shook his head:
"Nuclear reactors are different from gas turbines. In the final analysis, power generation still relies on steam to drive the turbine. Compared with direct drive, it has no advantages in noise and equipment size. Moreover, our mission is a once-in-a-century event. Under normal circumstances, the power consumption of the equipment on the ship is There is not much pressure, and there is no motivation in this regard..."
After saying that, maybe I felt that I would be slapped in the face if I judged so easily, so I added another sentence:
"Of course, I don't rule out that there will be more novel forms of power generation in the future, or that simple steam turbine technology and power management technology will evolve to a certain level, so that your idea can become a reality..."
Just as the two finished chatting about this topic, a slightly unfamiliar voice sounded again from the communicator inside the boat:
"Report, the radar has been started successfully and is capturing the transmitter signal, preparing to search for targets..."
Only then did Han Xiangjie realize that the person speaking was Xue Shijun, the technician in charge of operating the radar in the missile bay, but he deliberately lowered his voice.
Of course, anti-submarine detection equipment such as sonar is not magical enough to hear the voices and footsteps of people inside the submarine, as shown in the movies.
The frequency of the actual human voice is not conducive to long-distance propagation, so even shouting is not a big problem.
It’s just that laymen who have just boarded a boat are easily influenced by literary works and make unnecessary cautious behaviors.
After Han Xiangjie corrected the problem twice to no avail, he had no intention of continuing to try. He just took Fan Zhaohui with him and quickly came to the electronic chart table.
In just a few seconds, the radar had captured a target.
The other party’s basic information was quickly displayed on the screen:
It is about 175 kilometers away from the ship, speed 750km/h, course 220, altitude 16200 meters...
To be honest, when he saw the first few numbers, Han Xiangjie's heart even skipped a beat, almost triggering the submarine commander's instinctive reaction——
These data are really like a US Navy S3 carrier-based anti-submarine patrol aircraft.
Although its performance is not as good as common land-based models such as the P3C due to size issues, for a submarine floating on the sea, any aviation anti-submarine equipment is a natural enemy.
It wasn't until he saw the flight altitude parameters that he relaxed a little.
No anti-submarine aircraft could fly to such outrageous heights.
Sure enough, the information on the electronic chart was quickly refreshed, and a target model column was added.
Identified as a B52 bomber.
"Coming!"
Fan Zhaohui had been away from submarines for more than 20 years, so he naturally didn't know Han Xiangjie's complicated inner activities just now, but his eyes suddenly lit up, his upper body leaned forward, and he wanted to lie down on the chart table. The latter has seen more strong winds and waves in recent years, and is the supreme commander of the entire boat. Although he is very excited in his heart, he still behaves calmly.
He just walked slowly around to the other side of the chart table and pretended to have an overview of the whole situation.
In fact, his attention has long been focused on the target point that is rapidly approaching him.
an airplane.
An airplane actually appeared on the electronic chart.
For a moment, Han Xiangjie even felt a bit unreal.
The unilateral suppression of submarines by anti-submarine aircraft is largely due to the fact that submarines do not have reliable means of air observation.
By the time the search periscope saw the plane, it was already too late to do anything.
But today, he saw an approaching large aircraft 95 nautical miles away in advance.
"If that is really an anti-submarine aircraft..."
This book was recently updated in ##六@@九@@书@@!! Updated!
Han Xiangjie's brain began to work rapidly involuntarily.
This discovery distance means that he has at least 15 minutes to react in advance, such as diving to the maximum depth, or reducing some turbine power to reduce the target characteristics.
If it is a war, you can also use your superior body position to confront the enemy in advance to prepare anti-torpedo equipment such as air curtain grenades.
He even had enough time to lay out several mines and wait until the sonobuoy entered the water to detonate them remotely to interfere with the detection process or destroy the buoy itself...
Although I dare not say that I have the advantage, at least it is better than being caught off guard when sailing on the surface or in shallow water.
"It would be great if we could receive this kind of information from surface ships in normal times..."
Anti-submarine aircraft will fly at ultra-low altitudes when performing missions, but for range and safety considerations, they will still maintain normal cruising altitudes during the journey.
This means that surface ships can often detect them hundreds of kilometers away, thus providing cover for submarines located further forward.
Thinking of this, Han Xiangjie turned back almost subconsciously and glanced behind the control tower.
Of course nothing can be seen.
After hesitating for a moment, he left the electronic chart table, raised the search periscope again, and adjusted the observation direction to 180°.
What came into view was the mesh radar antenna that had stopped rotating.
This thing looks simple, but in fact it is even a phased array system, so after capturing the signal from the transmitter, there is no need for additional mechanical rotation to scan the information.
However, this picture still poured cold water on Han Xiangjie's fantasy.
Obviously, any submarine performing combat missions cannot carry such a huge antenna that can only be deployed on the water.
"That's right...it's impossible for me to catch up with all the good things..."
Han Xiangjie shook his head mockingly.
The world is fair.
Since the sea water has given the submarine excellent cover, it is reasonable to take away the ability to transmit electromagnetic signals as a price.
He lowered the periscope again and returned his gaze to the chart table.
At this time, the B52 was only 93km away from the ship.
According to the information given by their superiors before departure, their observation position at this time was about 90km away from the X51A release location...
Sure enough, before Han Xiangjie returned to the chart table, he heard Xue Shijun's voice on the boat's communicator:
"Report, the radar captured the B52 dropping a falling reflected signal..."
The chart table cannot visually display altitude information, so the displayed content has not changed significantly at this time. There is only a new entry in the target information column, and because the time is too short, the information is incomplete.
"This thing didn't ignite, right?"
Han Xiangjie thought with some evil humor.
If this is the case, then it would be a rare experience to watch the Americans' new equipment test failure live for the first time...
However, if it is 90 kilometers away, even including the distance of subsequent parabolic motion, it is already beyond the navigation range of the wire-guided UUV. It is probably too late to rush over to take samples.
However, just as he had this idea, a new signal point separated forward from the triangular icon representing B52, and exceeded the speed of sound in less than 1 second.
"The target starts to accelerate, repeat it, the target starts to accelerate!"
