As Li Anran finished speaking, various pictures were still rolling, the holographic projection screen of the drawings suddenly became "clean", leaving only an airship with a streamlined appearance and a silver-white color as the main color.

"The main data of the Yufeng I electromagnetic airship is as follows: the boat is 100 meters long, the maximum diameter is 25 meters, the airbag volume is 7,500 cubic meters, and the auxiliary airbag volume ratio is 25%. The pod is 14 meters long, the cabin is 10 meters long, the cabin is 5 meters wide, and the cabin is 4 meters wide."

"The main pod is four meters high (excluding landing gear) and four meters high in the cabin. The engine pod is located on the back sides of the main pod and is powered by two electromagnetic pulse engines. Only two drivers can control it, with a maximum load of 20,000 kilograms."

"The maximum ceiling is 5,000 meters, the maximum speed is 150 kilometers per hour, the cruise speed is 100 kilometers per hour, and the maximum battery life is 15 hours. The helium filled with the airbag is safer to use because it is an inert gas."

As various data and related pictures and drawings of this airship appear on the holographic projection screen, the Central Intelligent Brain Cortana also thoughtfully used her sweet voice to explain the main data of this airship.

Although he does not have a major in science and engineering, Anran Li can understand that this spacecraft uses helium rather than hydrogen commonly used in modern time and space as a source of air power, because hydrogen is relatively too dangerous.

With the airbag volume of this Wind I-type airship, it is easy to turn into a powerful bomb when it encounters danger. Not to mention that the personnel and cargo on the airship will become victims, even people and objects within a certain range will be affected.

It is different to use helium. To a certain extent, it can be said that the helium airship is definitely the safest aircraft in the world. Even if an accident occurs, it will only fall slowly unless all airbags leak light instantly, and will not play free fall like the plane.

Of course, compared to hydrogen or similar gases that can be used as floating airplanes, the only disadvantage of helium airships is that they are too small in quantity. It is much harder to get more hydrogen than the main road cargo. Fortunately, this is not a problem for Li Anran, who has black technology.

After all, looking at the entire universe, this gas accounts for 23% of the total mass, and its reserves are second only to hydrogen. But if placed on the earth, helium will appear much rarer and is a rare gas.

In fact, those who have studied high school chemistry should know that hydrogen is a very easy-to-get gas. There are at least dozens of methods that can be produced in large quantities, and the cost is cheap. But helium is different. To some extent, it can be said that success or failure or failure.

The reason why helium is safe is that this thing is inert gas, which can have one common feature. It is difficult to produce compounds, and the content in the earth's atmosphere is very low, only about 5 parts per million, and the output is quite pitiful.

Fortunately, with modern space-time technology, it can be extracted from natural gas. The price is not high. The bottle-shaped helium of 22 liters is only sold for more than 150 yuan online. Of course, it is still much more expensive than hydrogen.

After the intelligent brain Cortana put the information on helium manufacturing on the holographic screen at the request of Lee Anran, Li Anran was depressed to find that if he wanted to purchase a large amount of helium, it was more cost-effective to buy it from the United States.

There is no way, who makes people have a good territory? The average helium content in natural gas is 1.5%, and many can reach 7%. The highest number can even reach 15%, which is enough to make other countries so jealous that they can't cry.

What made Li Anran speechless was that, both natural gas, most of the helium reserves in his country's gas fields were below 0.2%, and the highest one would not exceed 5%. Compared with the two, this Nima was completely the gap between the rich and handsome man and the poor.

"Wait, Cortana, even if helium can be purchased directly from modern time and space, what's the case with electromagnetic pulse engines? Is this too advanced?" After understanding the problem of helium, Li Anran said, who suddenly thought of a problem.

"Compared with modern human technology in space and time, electromagnetic pulse engines are not very advanced. This technology has actually been invented, but it cannot be popularized for the time being due to the size and power of the equipment."

"And according to my penetration of modern space-time networks, and the human world is too dependent on the industrial chain formed by the old-fashioned energy system, even if there is no problem at the technical level and can be put into mass production, this technology will not be popularized."

"As the technological level that the commander has now invested in the time and space of the Tang Dynasty, the electromagnetic pulse engine does not exceed the limit of the corresponding range. Of course, the commander can also replace the engine with an ordinary diesel engine or gasoline engine, but the effect will be much worse."

Facing the answer from the Central Intelligent Brain Cortana, Li Anran had to admit that the other party made a lot of sense. Although the electromagnetic pulse technology is indeed very advanced, he did not intend to popularize it in the time and space of the Tang Dynasty, but it was still fine to use it himself.

Even if there are some high-level alien civilizations in this time and space, and at the same time, I have also discovered the electromagnetic pulse technology I use, I believe that I will not be able to follow the clues and see my true combat power, but can instead play a confusing role.

However, just after Li Anran accidentally clicked a picture and enlarged it, he couldn't help but be stunned when he saw clearly the front left, front right, center left, and rear left and rear six directions of the Wind I-type airship.

"I said Cortana, can you explain what these gun barrels are?" Li Anran asked with a black look on his face when the picture was enlarged.

"Commander, this is an M2 small-caliber rapid-fire electromagnetic gun with a caliber of 12.7mm and can fire 12.7×99mm small-caliber depleted uranium armor-piercing bomb. It can reach eight times the speed of sound at a fastest, with a rate of fire ranging from 1,500 to 3,000 rounds per minute."

"This small-caliber rapid-fire electromagnetic cannon is the standard configuration of the Yufeng series airships. It is specially used to deal with various attacks in the air and ground that harm the safety of the airship. It is a standard configuration." Cortana said while putting the relevant data on the holographic projection screen.

"Okay, do you want to tell me that the technological reserves of this thing do not exceed the limit?" Li Anran, who was too lazy to look at it, sat back on the overall control chair of the entire multi-function exploration spacecraft, and then asked.

"Yes, Commander." Cortana replied in a good manner.

"I admit that this thing is indeed very useful, but you are sure that just two people can completely control this airship that is faster than you?" Li Anran, who rubbed his eyebrows, asked helplessly.

"Yes, the commander, only two people are required to control the operation of all systems, including the flight system and the weapon system. And the cockpit is completely isolated from the cargo compartment and cannot be accessed without authorized outsiders," Cortana explained.

"Okay OK OK OK OK OK Since you recommended this, then this one." Li Anran, who knew that the other party was much smarter than him, shrugged and said, "By the way, you don't have to exceed the limit in terms of materials."

"Commander, please rest assured that the materials used in this Yufeng I airship are not exceeding the limit. However, considering that the demand for airships in the Tang Dynasty time and space cannot be as small as one or two, it is recommended to establish a supporting production line there."

"I knew it would be like this." Li Anran, who knew that he had no choice in this matter, said accepting his fate: "I agree to this matter. After pushing the original production sequence, we will manufacture the equipment of the relevant production line as soon as possible."

"By the way, remember to match me with enough engineering machinery, don't expect that there are enough skilled workers in the time and space of the Tang Dynasty to use it. Also, since it is a supporting production line, helium manufacturing is also included, right?"

"Yes, Commander." Cortana replied.
