Integrated electric propulsion system? What is this? Everyone's eyes widened.

"We know that in previous warships, the engine directly drove the propeller forward. At the same time, there was a special generator to provide power to the warship. In the past, this method only required a light bulb, or later a few anti-aircraft units were added.

In the case of radar, there is no problem, but now, there are more and more electrical equipment on warships. Various radars, various missiles, computers and other systems all need to consume a lot of power. This kind of

Then something goes wrong.”

Qin Tao explained to everyone: "For example, if a warship wants to sail at high speed, the power of the engine needs to be high enough. At this time, the warship only needs to turn on an air-to-sea search radar, so at this time, it generates electricity

The power of the engine is surplus. Wouldn't it be better if the excess power can be used to drive the ship? For another example, on the battlefield, the warship needs to cruise. At this time, the speed is reduced and the power of the engine is redundant. However,

After various devices are turned on, the power required will increase significantly, and even if all the generators are turned on at the same time, it may not be enough."

This principle is very simple and everyone can understand it: if you need to sail at high speed, give energy to the propeller; if you need to start various equipment, give energy to electronic equipment. The distribution of electricity is very simple, and the distribution of mechanical power will be very simple.

Difficult, so a brand-new technical route came out: all the power on the warship is used to generate electricity, and then the electric energy is redistributed!

For aircraft carriers, this method is even more important. Electromagnetic ejection and electromagnetic interception both require a large amount of energy. If a comprehensive power system is not developed, it will either be a waste or not enough.

"Do you still have such a system?" Everyone present was shocked.

"Of course." Qin Tao said: "Now, our Aegis warships already use this system, and we also plan to use this system for the new warships with a displacement of tens of thousands of tons developed by ourselves."

The construction progress of the aircraft carrier is very fast. Now, the first section has been welded. It can be clearly seen from here that although the Easterners do not tell the outside world, the Saudis can still guess something in their hearts.

When the driver is not integrated, this system is not difficult. The 002 aircraft carrier must be installed, but it is difficult to add the driver.

After all, the power required to drive an aircraft carrier is too great.

Let’s take the Queen-class aircraft carrier as an example. After all, this aircraft carrier is the first to use an integrated electric propulsion system. To this end, it uses two 36-megawatt MT-30 gas turbines, plus two 9-megawatt single-machine power turbines.

Ceylon 12v38b diesel generator set. In this way, the maximum output power of the main power system is 108 MW, of which 80 MW is used to drive 4 advanced induction motors of the French Corfud Electromechanical Company with a single power of 20 MW. The total propulsion power is 10.8

Ten thousand horsepower allows this 65,000-ton aircraft carrier to reach a top speed of 26 knots.

At present, the largest domestic marine propulsion motor is of course still the 095 nuclear submarine. The permanent magnet propulsion motor used on it is 20 megawatts, which is already the most powerful in this era.

To use it to push the 80,000-ton 002 aircraft carrier, I'm afraid you need more than eight units. This is absolutely impossible. Now, there is no problem using it to push the 40,000-ton aircraft carrier. Four units are enough to push this aircraft carrier.

At 30 knots, big players have high requirements, and they will definitely look down on aircraft carriers with 25 or 6 knots.

"The biggest benefit of using this integrated electric propulsion system is that it omits the transmission shaft and reduction gearbox. These things not only occupy a lot of space, but also produce noise during operation." Qin Tao continued to lie:

"Therefore, our advanced warships have abandoned this backward approach. The entire warship uses electric propulsion, which is the most appropriate solution."

Now, these people are left to listen. To them, this is a fantasy.

"We currently plan to use four boilers to drive two steam turbines as the main engine with a power of about 120,000 horsepower. At the same time, we will also provide two generator sets with a single power of 8 megawatts. In this way, the power of the entire warship will exceed 100

MW, in addition to driving four drive motors, there is still enough power left for other power equipment." Qin Tao continued to introduce.

"boiler?"

Hearing Qin Tao say this, the wealthy people present showed dissatisfied expressions on their faces.

"Yes, everyone, currently on warships with tens of thousands of tons, gas turbines are the best choice." Qin Tao introduced: "After all, everyone should know that the power of gas turbines is not that high."

The most mature one in China is the GT gas turbine, which has a power of only 20 MW. If you want to reach 100 MW of power, you have to use at least five gas turbines. Even if you are a big business and don't have money, you can't design the air inlet and outlet. The gas turbine needs

The chimney is much larger than the boiler, and when the time comes, even the twin ship islands may not be enough.

If the British MT30 gas turbine was developed, a single unit would have 36 MW, and two units would be possible. Since the 60,000-ton Queen class can be pushed to a speed of 26 knots, a 40,000-ton aircraft carrier can reach 30 knots.

no problem.

However, this kind of gas turbine has not yet appeared. Even if it exists, it cannot be used, because this thing does not consider the needs of the tropics.

You have to lie down.

Therefore, Qin Tao does not like gas turbines at all.

At this time, everyone fell silent after hearing Qin Tao's words.

The power of a gas turbine is indeed not that great. If a gas turbine is not used, there is no other choice but to burn a boiler!

"Unless you want nuclear power." Qin Tao said, "If you use two nuclear reactors and two gas turbines, it will be almost enough."

At present, domestic mature nuclear reactors are used on nuclear submarines. Although the thermal power of a single reactor reaches 150 megawatts, it is good to have 30 megawatts left when it is used in generators.

Two nuclear reactors, 60 megawatts, are enough for normal cruising. If power is needed, two more gas turbines can be turned on to make up 100 megawatts.

Salman shook his head: "No, it may be difficult for our region to accept nuclear-powered aircraft carriers."

Let’s talk about nuclear discoloration. When Shadamu built a nuclear power plant, it was directly bombed by the Israelis who attacked from a long distance. If they send a nuclear-powered aircraft carrier back, the balance of the entire region will be completely broken.

"So, besides burning the boiler, do you have any other options?" Qin Tao asked.

"There is really no other choice, so let's burn the boiler." Salman agreed!

Boiler power, all-electric propulsion, this is probably the only ship in the world! Qin Tao was also very emotional, as expected, the money of big dogs is easy to make!

The deck has been talked about, the power has been talked about, and the rest is easy to talk about.

"The hangar below can accommodate about twenty-five carrier-based aircraft. Including the number of decks, the total carrier-based aircraft can carry 55. However, considering the actual situation, you only need to carry about forty aircraft when going to sea normally.

A carrier aircraft is enough, and this kind of strength is enough to dominate the entire region." Qin Tao said.

"No, let's purchase sixty of them and get some more backup machines," Salman said.

Money is not a problem, the wealthy people have enough confidence!

Everyone present was shocked. This was their first time dealing with Saudi Arabia. They didn’t expect them to be so arrogant!

"In order to ensure more efficient operations, you also have to operate a group of carrier-based helicopters, including anti-submarine, maritime rescue, airborne early warning and other tasks." Qin Tao said: "I recommend that you purchase our Zhiba."

"Airborne early warning?" Salman became curious. Last time, Qin Tao brought up the matter of airborne early warning aircraft to command stealth aircraft operations. He knew that the Orientals had professional airborne early warning aircrafts, and he also expected the Orientals to modify a few c-

130 was used as an early warning aircraft, but he did not expect that the Easterners also had an early warning aircraft on a helicopter platform.

"Yes, our current 001 aircraft carrier cannot operate fixed-wing early warning aircraft, but our aircraft carrier also has early air warning requirements, so we modified the airborne early warning aircraft on the helicopter platform."

"Is it the same as the British Sea King helicopter?" Someone asked.

On the ground or on a ship, radar is affected by the curvature of the earth. When detecting ultra-low-altitude aircraft, the distance will not exceed 40 kilometers.

In the Falklands naval battle that year, Argentina relied on the cover of the curvature of the earth and used the Super Ensign to quietly approach the British aircraft carrier formation, and then launched sea-skimming Exocet missiles. The results were remarkable. If they had had a few more Exocet missiles in their hands at that time,

Missiles, the pattern of the world might really be rewritten.

Just as the road is high, the devil is high. With the tactics of ultra-low-altitude penetration, there are also ways to counterattack. Airborne early warning aircraft have begun to become more and more important.

Once radar is put into the sky, those ultra-low-altitude sea-skimming aircraft will be clearly visible and invisible.

If you want to have a long enough detection time and a far enough detection effect, you must have a professional fixed-wing early warning aircraft. However, for ordinary warships, it is too difficult to operate a fixed-wing early warning aircraft. The helicopter platform is convenient for taking off and landing.

Become a better tool.

However, the helicopter body is small, so how to detect it is a big problem.

The British used a side-mounted method, placing the radar on the side of the aircraft body, and adding a radome on the outside to form a big ball. When taking off and landing, it turned to the horizontal direction to retract it, and when in use, it turned to the bottom.

Due to their close relationship with the West, the first thing they thought of was the modification plan of the Sea King helicopter.

Qin Tao shook his head: "Of course not. That kind of radar is too backward. We are now using the most advanced technology in the world. Tomorrow, I will take you to the flight test institute to have a look."

"Can we see your most advanced early warning aircraft?" Salman also became excited.

"Yes, it is our most advanced early warning aircraft. However, due to confidentiality and other reasons, we need to contact our superiors first and confirm it before we can do it. Now, let's move on to the next project, the problem of electronic equipment on the ship island."

The Saudis could no longer sit still. They were so excited at the thought of visiting the early warning aircraft. Anyway, the aircraft carrier technology in the East has matured, and any electronic equipment needed has been installed.

After talking about various detailed issues for a full hour or two, the day's trip was over. Next came the banquet and celebration. The next day, everyone took a special plane to the flight test center.

Any country that can develop fighter aircraft needs a specialized flight test institution. Whether it is testing or finalizing, a professional flight test institute can better handle various problems.

Lao Maozi's Zhukovsky Test Flight Institute is famous all over the world, and there are similar institutions in China.

When the plane landed on the runway, the first thing Salman and others saw was the most dazzling plane carrying a big plate.

The Air Police 2000 has completed its test mission and been delivered to the troops. It is still being tested at the Flight Test Institute. They are two early warning aircraft modified from the Y8 body. One is a large plate and the other is a balance beam. Due to this

The airframe platform will not be restricted, and the price of the airframe can be reduced at the same time, so this early warning opportunity becomes the backbone.

As for the carrier-based early warning aircraft, it is still being installed and debugged in the factory and has not yet reached the stage of test flight.

"This early warning aircraft of yours looks a bit small." Salah asked.

Saudi Arabia also has early warning aircraft. The early warning aircraft purchased from the United States are the world-leading equipment they are most proud of. The early warning aircraft modified using the body platform of a passenger aircraft is of strategic level and is very large. But the one in front of you looks like

Very small.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Yes, these are tactical early warning aircraft." Qin Tao said: "They are modified using our Yun-8 as a platform. If you plan to use c

If the -130 is modified for us as an airframe platform, it will be of this size."

"Yes, we have an idea to use C-130 to modify it. Qin, can we go up and have a look?" Salman was already eager to try it.

"We can't rush this yet. We have not made an appointment in advance and need to apply to the relevant departments. Everyone, we can go and take a look at the helicopter-modified early warning aircraft first."

Everyone followed the direction of Qin Tao's finger and saw the helicopter parked on the other side.

There is no big ball on the side of the helicopter, and it looks no different from an ordinary helicopter.
