104. High-speed maneuver test
In the quiet bridge, Li Sailieu's eyes glanced back and forth on Mu Feng and Liaoning several times.
During the Nanchang sea test that day, Mu Feng promised Crimson and let her run to 35 knots.
At that time, Li Sailiu instinctively didn't believe it, so when Mu Feng asked if he wanted it, Li Sailiu instinctively thought that she was coaxing Crimson to play, so he refused with a smile.
Now look, what this guy said is true.
60,000 tons can run to 39 knots, and 40,000 tons can run 35 knots, isn't it a piece of cake?
Compared with the astonishment of the audience, Mu Feng thought that after the speed of the ship reached a threshold, the power consumption would soar significantly.
According to calculations, the Liaoning that has been renovated only needs 240,000 horsepower for 35 knots.
But at the 39-knots limit speed, it must have consumed all 380,000 horsepower.
Correspondingly, the fuel consumption at this time must be very amazing.
Feeling the sea breeze, Mu Feng swallowed his saliva, and hurriedly said to Liaoning:
"Okay, okay, sister, we just know how fast we can run at most, now test the performance and consumption of 35 knots, and then practice carrier-based aircraft scheduling!"
Liaoning thought for a while: "Isn't there another high-speed maneuver test?" ”
Mu Feng blinked his eyes and remembered a video of an aircraft carrier driving at full speed at sea and running out of an S-shaped trajectory, with the entire deck tilting back and forth repeatedly.
The first reaction of those who watch is whether the plane above will fall off!
And the picture in Mu Feng's memories soon appeared in front of him.
Liaoning began the so-called high-speed maneuverability test, with the huge body turning at maximum speed.
The waves behind the stern of the boat form a white S-shaped trajectory.
And the people inside the bridge suffered, one moment to the left, the other to the right.
Mu Feng hugged a pillar with both hands to fix his body, and his ears seemed to remember familiar music:
“Déjà vu……”
Subconsciously looking back, I saw Neptune open the ship's suit, and one of the white balls was playing drag racing exclusive music.
She herself was swaying back and forth to the music, but she was so excited that the aircraft carrier turned abruptly, and she didn't grasp one of her hands, and her body directly clumped together, rolling from one end to the other on the floor, and hitting the wall.
The music stopped abruptly, and it seemed that the ship's stereo had been broken.
Luckily it was in Cambridge, not on deck, otherwise she would have been able to fly into the sea.
Mu Feng looked at the tumbling Neptune, suddenly remembered something, and didn't bother to care about Neptune, and shouted to Liaoning:
"Airplanes! Sister, is your plane fixed! ”
Liaoning smiled and nodded: "Commander, rest assured, of course it's fixed!" ”
Liaoning's full-speed sea racing lasted almost an hour, and the boilers and turbines did not show any instability.
The quality of the equipment made by using the magical material of the primordial substance is simply good.
As long as you give yourself clear parameters, they can almost always be implemented.
An hour later, the speed of the Liaoning was reduced to 35 knots, and the passengers, who had been rocked to the point of weakness, were finally able to settle down.
The Liaoning then quickly turned its bow and began to try to use the catapult to release the aircraft.
The Liaoning is equipped with three electromagnetic catapults, two on the foredeck and one on the beveled deck.
Many people think that electromagnetic catapults consume a huge amount of electricity, which can only be supplied by nuclear-powered aircraft carriers.
But this is a complete and beautiful misunderstanding.
The difficulty of electromagnetic catapult is not the amount of power generated at all, but the storage and discharge equipment.
In the case of the existing Ford-class, for example, the two reactors on the ship are used to run away, and have nothing to do with catapults.
Its four electromagnetic catapults are powered by a single 16MW diesel generator set.
16MW is converted to less than 22,000 horsepower, which can be supplied by any large warship.
As long as the storage and discharge equipment is done, there is no problem with electromagnetic catapult for conventionally powered aircraft carriers.
After the Liaoning has a catapult, the fighters at all take-off points can take off with heavy loads.
It's just that there has been a certain change in the scheduling method, and it needs to be re-adapted.
After Liaoning released one plane from three catapults, he closed his eyes and pondered.
Mu Feng asked beside him, "How do you feel?" Is it difficult? ”
Liaoning thought for a moment, released three more planes, and then said:
"Overall, it doesn't feel like it's getting much more difficult, because before, the scheduling and arrangement of the aircraft needed to be carried out around the take-off point of the heavy load, so it would be tied.
"Now I have broken the shackles all of a sudden, and I have become much freer, and the amount of operation seems to have become larger, but the overall efficiency has naturally improved."
Mu Feng nodded slightly, listened beside him, and continued to watch Liaoning's operation, one fighter after another took off, and by the way, wiped out a team of deep seas in the distance.
Catapults have many advantages to use, especially the new generation of electromagnetic catapults.
The thrust of the steam catapult is only a few orders of magnitude, but the electromagnetic catapult can be freely adjusted through the control system, from a few tons to dozens of tons.
The steam catapult has the largest force at the beginning of the moment, and it becomes smaller and smaller at the end, which requires very high structural strength of the aircraft fuselage, and the pressure on the pilot's body is also very great at the moment of starting.
The electromagnetic ejection thrust is stable throughout the ejection process, which greatly reduces the structural strength requirements of the aircraft and greatly reduces the damage to the pilot.
Steam ejection is a cumbersome matter to maintain, and the high-pressure steam produced by the power boiler is sent to the cylinders at the front of the deck through special pipes.
The mechanical structure of nearly 100 meters long and weighing hundreds of tons needs to be maintained once after 500 uses, hundreds of people are required for one maintenance, and a deployment cycle of 18 months must be completely disassembled and replaced.
Relatively speaking, electromagnetic catapult is a modular structure, which is easier to install and maintain, and no longer requires high-pressure pipelines and no longer needs to consume boiler steam.
Finally, steam catapult to electromagnetic catapult is not a skill upgrade, they are two different branches of technology, the difference between driving a boat and driving a car, and there is no inheritance between each other.
Proficiency in steam catapult does not promote the study of electromagnetic catapult.
It's like an assault rifle and a bow and arrow in front of you, both learned from scratch, who will learn a bow and arrow?
For China, giving up steam catapult and starting to explore directly from electromagnetic catapult is a matter of course for overtaking in corners, and it is abnormal not to overtake.
Liaoning continued to fly and recover the plane, and after repeated testing for more than an hour, he said to Mu Feng:
"In the current state, I can fly more than 40 tons of aircraft, but the J-15 is only 32 tons when it is fully fueled, and there is still a very large margin for catapults and speeds.
"I tried to add a drop fuel tank or increase the bomb load from 5 to 8 tons, and I was still able to take off easily, but the airplane was almost at its limit.
"If the load capacity continues to increase, the structure of the fighter will not be able to support it in the first place, and the range and maneuverability will be affected to a certain extent......"
Mu Feng nodded slightly: "After the catapult matures, we now need a fighter-bomber similar to the J-16 to work with the current J-15." ”
The J-16 is known as an aerial bomb truck and can hang up to 12 tons of ammunition, which is almost twice as large as the J-15.
