Of course, if conditions permit, even large aircraft use electricity as energy and motors as engines are all necessary. Unfortunately, with their Tiangong Technology's technology, they do not have the ability to replace turbojet and large bypass turbofan engines for the time being.

Therefore, in terms of turbofan engines, Wang Bin and Tiangong Technology must develop them. It is precisely because of this that Professor Kao and others focus on the research and development of large bypass turbofan engines.

Although the core engine of this turbofan engine is the same as the core engine of the previous tg001 turbojet engine, which can greatly shorten the R&D cycle, take the turbofan engine that Wang Bin is now in front of him. The drawing design time is only a few months. Professor Kao and others handed over this design drawing to Wang Bin.

However, Wang Bin would not pay much attention to this engine just because the core engine was the core engine of the previous engine. On the contrary, because this engine is the first large bypass ratio of Tiangong Technology's I-fan engine, he attached great importance to it, otherwise he would not have checked this engine in person.

Of course, if it were in the past, he would never be able to understand the drawings of this engine with his ability. However, since he purchased the rocket engine technology from the system last time, he found that even in the rocket engine technology, there are many technologies that have certain connections with aircraft engines. Therefore, among these knowledge, there are some technologies of aircraft engines. It is precisely with this knowledge that Wang Bin can understand this drawing and even know the purpose of most of the parts in this drawing.

However, just as Wang Bin was looking at the drawings, his phone rang. As soon as the phone was heard, a sound that made him somewhat familiar and unfamiliar came out of the phone.

"Mr. Wang! Hello, I am Du Haili of Kunlun Aircraft Manufacturing Company."

"Hello! Mr. Du! I wonder if you have already thought about it and are planning to use electricity as the power of your Kunlun Company's helicopter?" When he heard that it was Mr. Du of Kunlun Company calling, Wang Bin had a certain idea. It must be that Kunlun Company was preparing to develop and use electricity as helicopter power. Otherwise, Du Haili would not have called him specially.

"Yes, I'm going to try it. After all, with the current situation of our engine, it is absolutely impossible to go to heaven. After the last test flight, it crashed. Even if it is a test flight, if the engine matter is not solved, we dare not test flights.

However, I think Mr. Wang, you know the character of large foreign companies. Even if I buy another engine of theirs, they may not be able to give me a qualified engine. What's more, if another engine is replaced, the performance and safety of the helicopter will be greatly reduced.

So since that's the case, I simply stopped using engines from large foreign companies and just prepared to try it out so electric power as power, what if it succeeds!

If it is really possible, then our company will no longer be restrained by foreign companies in the future.

And this time I called me to confirm with Mr. Wang, is your company really capable of solving the battery problem?" Mr. Du said on the phone.

"Okay! Since Mr. Du is really planning to use electricity as the power and energy of your company's helicopters, I won't hide it anymore.

Our company does have high-performance batteries, and their energy density is not comparable to those on the market today, and there are more than one.

The energy density ratio of the first type of battery is about 100 kilowatts per kilogram, that is, about one kilogram per battery, and can store 100 kilowatts of electricity.

However, this kind of battery also has its own shortcomings, that is, the output power and output voltage of this kind of battery are very limited. The maximum output power is only 100 kilowatts, and the maximum output voltage cannot exceed 300 volts.

Although the energy density of the second battery is similar to that of the first battery, and is 100 kilowatts per kilogram, the weight of the second battery can reach about five kilograms, which means that the maximum power storage capacity of each battery can reach 500 kilowatts.

At the same time, the output power and voltage are also much higher, reaching 500 kilowatts and 500 volts.

The most important thing is that although this battery, like the first type of battery, cannot be powered in series, it works in parallel.

Unfortunately, since the second type of battery is a product that cannot be sold easily, if Mr. Du really needs to buy it, he must first get a license." Wang Bin said.

After hearing Wang Bin's words, Du Haili, who was on the other end of the phone, felt relieved all of a sudden. After all, not to mention the second battery, even the first battery is enough for the helicopter developed by their company. After all, this is a 100 kilowatts of power storage! Even if the helicopter developed by their company has consumed 10 million, which is only one kilometer of electricity, it can definitely make their helicopter last for a range of 100 kilometers.

So even the first type of battery is enough for their helicopters, let alone the second type of battery. If the second type of battery can be obtained, the helicopter developed by their company can increase its endurance to at least 500 kilometers, which is absolutely enough for a civilian helicopter.

As for the second type of battery, Du Haili is confident that he can handle the procedures required.

So he immediately said to Wang Bin: "Mr. Wang! Your Tiangong Technology has really developed high-performance batteries! That's really great. With your two types of batteries, I think it's not that easy for foreign companies to get stuck in our Kunlun Company's neck!" Du Haili said happily.

Then he thought of the electric engine again. After all, if he wanted to make a helicopter fly, it would not work just to solve the energy problem. He also had to solve the engine problem.

Now that Tiangong Technology has the ability to develop batteries with such excellent performance, it means that Tiangong Technology has absolutely not simple technology in power and energy. So he knows that Wang Bin and his Tiangong Technology will definitely have high-performance motor technology.

So he asked Wang Bin again: "Mr. Wang! What about the electric engine technology? I wonder if your company has high-performance supporting electric engine technology?"
