Chapter 1320 Earth OL's Balance Mechanism
As Han Xiangjie gave the order, the cover of the light green cylinder in the No. 8 launch tube made a "bang" sound, and then quickly bounced upwards.
This was a step that did not exist in previous training.
Most submarine-launched missiles launched from launch tubes rather than torpedo tubes are directly installed in the tubes, and water is injected into them before ignition, and then ignited underwater.
Even some dry-launch models will use high-pressure gas or projectiles to directly break the second layer of the cover.
After all, the radar components this time still need to be considered for recovery, so the container design is quite sophisticated.
A few minutes later, amid the hum of the hydraulic booster, a cylindrical device like an umbrella frame rose from below, and then unfolded into a rectangular grid antenna with a size of 2.5 meters * 8 meters, and began to rotate slowly at a speed of about 3r/min.
"Report to the captain, the antenna array is powered on successfully."
In the communicator inside the boat, the chief engineer in the front auxiliary engine room began to report the situation:
"The generator set is working at a high load, but the operating parameters and noise are still stable..."
Due to the hasty modification time, this radar has not been fully connected to the command system of the Long March 9. The technicians only had time to separate a line from the signal system so that everyone in the command cabin could see the search results on the multi-function display and the electronic chart table, but the control operation still needs to be completed under the rear missile compartment, and the power is also directly supplied by the front auxiliary engine room.
"Pay close attention to the operation of the equipment, and report to me immediately if there is any fluctuation."
Han Xiangjie ordered.
"Received."
A brief response came from the other side.
In the previous training process, he found that the power consumption of this radar far exceeded his estimation.
Although the nuclear reactor can provide almost unlimited energy on paper, most of it will be transmitted to the main shaft through the gearbox as propulsion power, not to mention that the front auxiliary engine room is still completely independent, so the power supply is not as abundant as many people imagine.
After successfully completing this step, the following task flow has little to do with the crew team-
There are basically no professional radar positions on the submarine, so more than a dozen comrades recruited from the surface ship force and the China Electronics Group are responsible for operating the equipment.
As the captain, Han Xiangjie also has time to think about other things.
"I say, Lao Fan, now the power management technology has also improved. Is it possible for future nuclear submarines to return to the 09I and 09II, first use nuclear reactors to generate electricity, and then distribute electricity to the power and equipment separately?"
Taking advantage of the time to debug the radar later, Han Xiangjie asked Fan Zhaohui.
The early models of Huaxia nuclear submarines used the steam turbine-motor propulsion scheme, and even had a bit of the flavor of an integrated power system.
But just like the electric drive tanks in the early years, it sounds quite sci-fi, but in actual use, both performance and reliability are quite sorry, so on 09III and 09IV, they still honestly used the traditional technical route.
However, after experiencing today's experience, Han Xiangjie suddenly remembered the few advantages of the old models.
Fan Chaohui pondered for a moment after hearing this, and finally shook his head:
"Nuclear reactors are different from gas turbines. Power generation ultimately depends on steam-driven turbines. Compared with direct drive, they are not superior in terms of noise and equipment size. Moreover, our mission this time is a once-in-a-century event. Under normal circumstances, the power consumption of the equipment on the submarine is not great, and there is no power in this regard..."
After saying this, perhaps because he felt that it was easy to be slapped in the face for making such a hasty judgment, he made up another sentence:
"Of course, it is not ruled out that there will be some newer forms of power generation in the future, or that pure 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 talking about this topic, a slightly unfamiliar voice sounded again in the submarine communicator:
"Report, the radar was successfully started, capturing the transmitter signal, and preparing to search for the target..."
Han Xiangjie realized that the person who spoke was Xue Shijun, a technician who was responsible for operating the radar in the missile compartment, but he deliberately lowered his voice.
Anti-submarine detection equipment such as sonar is certainly not as magical as in the movies, which can hear the voices and footsteps of people in the submarine.
The frequency of actual human voice is not conducive to long-distance transmission, even if you shout, it is not a big problem.
It’s just that laymen who have just boarded the boat are easily influenced by literary works and make some unnecessary cautious behaviors.
After Han Xiangjie corrected it twice without success, he didn’t plan to continue trying, but took Fan Zhaohui and walked quickly to the electronic chart table.
In just a few seconds, the radar has captured a target.
The basic information of the opponent was quickly displayed on the screen:
It is about 175 kilometers away from the boat, the speed is 750km/h, the course is 220, and the altitude is 16,200 meters...
To be honest, when Han Xiangjie saw the first few numbers, his heart even skipped a beat, and almost triggered the instinctive reaction of the submarine commander-
These data are really too much like a US Navy S3 carrier-based anti-submarine patrol aircraft.
Although due to the size problem, the performance is not as good as common land-based models such as P3C, but 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..."
Please...you...collect 6...books...!
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 a few mines and detonate them remotely after the sonobuoy entered the water 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 on a regular basis..."
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 content displayed at this time has not changed significantly. Only a new entry has been added to the target information column, and because the time is too short, the information is incomplete.
"Isn't this thing failing to ignite?"
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 begins to accelerate. Repeat, the target begins to accelerate!"
