Chapter 2973: Modify a warship experiment

The sound of the No. 2 motor began to become louder, and it has malfunctioned. This type of malfunction is multifaceted. For example, the propeller entangles the fishing net, and it becomes tighter and tighter. Finally, the motor is overloaded. After the overload, the consequences will be It will be serious, any motor burning is secondary and important, and it may cause the entire ship to trip.
Qin Guan looked at it carefully. These technologies are the top priority in the all-electric propulsion system. Just like electric vehicles, many people think that they have no technical content. Isn't it just a pile of 18650 batteries? In fact, how to stack batteries and how to manage these batteries is the expertise of Tesla. Outsiders can learn a little, but they can't learn the truth.
Now, the same is true for medium-voltage direct current transmission. It is actually easy to solve with generators and motors, but its reliability is difficult to solve. Once problems are encountered, how to deal with them, even the system automatically Solving these problems and improving its reliability are the most important.
As a power system, the short-circuit and overload protection capabilities of this system are the most important. If it cannot be solved in time, the entire system will be cut off at any time. After all, there is absolutely an overload protection device on the generator side for insurance. Once the fault point cannot be disconnected in time, the generator must be cut off.
Now, when an electric motor is overloaded, when the drive shaft of the motor comes to a complete stop, the electricity will be completely converted into heat, which will burn all the circuits in a short period of time. At this time, a red color appears on the screen. Alarm, and then, in the next second, or the next 0.1 second, the electric circuit of that electric motor is cut off.
The system automatically determines the fault problem and then deals with it. All of this is done beautifully.
"Well, yes, this is also our difficulty." Qin Guan said: "Our system is doing very well."
Professor Ma’s face was also excited: "Yes, we have been working on this aspect for the past few years. The pre-research is already sufficient. We believe that the next step will be used in our 10,000-ton large-scale drive. , There is no problem."
Just after he had said this, Makarov shook his head over there.
"Lao Ma, do you have an opinion?" Qin Guan asked.
Makarov nodded: "Yes, I have an opinion."
Since Makarov has been in Han, he has only concentrated on his own work. He has never expressed any opinions about those that have nothing to do with him, but it is different now. After all, although it is used for 10,000 tons of large-scale drives, in the future It will also be used on aircraft carriers. Now the land model here performs very well, but if it is directly used on the 10,000-ton large drive, it will not work.
"This land model, no matter how many conditions are considered when designing it, is still imaginary. In real use, no one knows what problems will occur." Makarov said: "So, just After such an experiment, a 10,000-ton large drive, or even an aircraft carrier, will be used. I think the risk is too great. After all, if something goes wrong, I am afraid that there will be a big trouble."
Makarov’s worries are not unreasonable. After all, experiments are always experiments, and it is impossible to completely simulate the real situation. When it was created, various problems appeared during use and could not be solved. The warship was taken apart and replaced with a normal plan? That is not much different from rebuilding a new ship.
At that time, who can bear such responsibility?
When Qin Guan heard Makarov's words, he was also emotional. Sure enough, Jiang was still hot. Makarov had built a warship for a lifetime. He pointed out this big problem and couldn't take risks.
Think of Niu Guoren’s Type 45 destroyer, think of the Eagle State’s aircraft carrier. This kind of major problem has arisen, and the navy has used it quite a lot. This is only in peacetime. What if it is at war?
In the military’s equipment, backward technology bidding over advanced technology often occurs. After all, the backward technology is enough and the reliability is still very good. Take the aircraft, the YF23 is quite advanced and far exceeds After YF22, YF22 was repaired and YF23 was put on the shelf. This is from the perspective of reliability.
In Qin Guan’s plan, all-electric propulsion is definitely required. After all, there are more and more electronic equipment on warships. The electricity required by Aegis warships is exponentially increased. Only this kind of all-electric propulsion can A reasonable distribution of power supply has great benefits.
Moreover, in the future, naval guns will transition to electromagnetic guns, which also require sufficient power supply. As for aircraft carriers, it is necessary to use electromagnetic catapults during catapult takeoff. There is no need to produce a large amount of water vapor, and there is no need to worry about cold areas. The deck is icing, and the power of electromagnetic ejection is continuously adjustable. Future drones must use electromagnetic ejection to take off.
Electric drive is a road that must be traversed. Now that we have stepped down, we can only go on unswervingly. Then, how to solve it?
Hearing Makarov’s words, Professor Ma’s face was not embarrassed, but with an expression similar to what the hero saw: "Yes, in fact, we also want to practice it, but this is too costly, not so. It's easy to pass."
Now to build this land model, even if it uses two old marine diesel engines, it costs a lot. It costs millions of dollars. If the actual warship is used to transform it, it will cost even more. You know, this is about the power system of the warship. Cut off the drive shaft of the warship. At the stern of the ship, place the electric motor. At the place of the engine, the drive shaft comes out to connect to the generator. The volume of these things is not small, at least You have to make a big hole on the deck.
I'm afraid it will cost tens of millions of investment. With such a large investment, they can't be the master of 7712, not to mention that they have to have warships.
Hearing this, Qin Guan turned to look at General Zhang, and said to General Zhang: "General, our navy is rapidly entering the modern sequence. The previous brigade-level class should be gradually retired, right?"
The brigade class must be decommissioned. Warships that rely on anti-aircraft artillery for air defense have no effect at all in modern warfare. Even if there is a transformation plan, it is completely worth the loss. After all, the navy has already begun rioting. , The Aegis warships have been built continuously, and the brigade-level class will not be changed to the point where the Aegis warships are changed.
General Zhang nodded: "That's right."
"In that case, the Navy will issue a decommissioned Lvda-class warship that is still in good condition, and our North Industries Corporation will provide funds for modification. I will develop such an experimental warship to verify our all-electric propulsion power system. Reliability.
After finishing speaking, Qin looked at Professor Ma:
Is there a problem with our modification plan?
