As soon as Li Anran finished speaking, various pictures were still scrolling, and the holographic projection screen of the drawings suddenly became "clean", leaving only one with a streamlined appearance, mainly silver-white.

Toned airship.

"Yufeng I-type electromagnetic airship, the main data are as follows: the length of the boat is 100 meters, the maximum diameter is 25 meters, the airbag volume is 7500 cubic meters, and the auxiliary airbag volume ratio is 25%. The pod is 14 meters long.

It is ten meters long, five meters wide, and the cabin is four meters wide."

"The main pod is four meters high (excluding landing gear), and the cabin is four meters high. The engine pods are located on both sides of the rear of the main pod and are powered by two electromagnetic pulse engines. Only two pilots are required to control it.

The maximum load capacity is 20,000 kilograms.”

“The maximum service ceiling is five thousand meters, the maximum speed is one hundred fifty kilometers per hour, the cruising speed is one hundred kilometers per hour, and the maximum endurance time is fifteen hours. The helium filled in the air bag is an inert gas, making it safer to use.

"

As various data and related pictures and drawings of the airship appeared on the holographic projection screen, Cortana, the central intelligence brain, also thoughtfully explained the main data of the airship in her sweet voice.

Although he does not major in science and engineering, Li Anran understands that this spacecraft uses helium instead of the hydrogen commonly used in modern time and space as the source of floating power, because hydrogen is relatively too dangerous.

.

With the size of the airbag of this Yufeng I-type airship, it can easily turn into a powerful bomb if it encounters danger. Not to mention the people and cargo on the airship will become victims, and even people and objects within a certain range will become victims.

Everyone will be affected.

The situation is different when using helium. To a certain extent, it can be said that a helium airship is definitely the safest aircraft in the world. Even if there is an accident, unless all the airbags leak instantly, it will only fall slowly, not

It will free fall like an airplane.

Of course, compared to hydrogen or similar gases that can be used as floating gases, the only disadvantage of helium airships is that the quantity is too small, which is much more difficult to obtain than commercially available hydrogen. Fortunately, this is a problem for Li Anran, who possesses black technology.

It's not a problem to say.

After all, looking at the entire universe, this gas accounts for 23% of the total mass. In terms of reserves, it is only second only to hydrogen. But if it is placed on the earth, helium is much rarer and is considered rare.

gas.

In fact, anyone who has studied high school chemistry should know that hydrogen is a very easy to obtain gas. There are at least dozens of ways to produce it in large quantities. And the cost is relatively cheap. But helium is different. To a certain extent, it can be said that it is also Xiao He.

Xiao He is also defeated.

The reason why helium is safe is that it is an inert gas. But inert gases have a common characteristic. It is difficult to produce compounds, and the content in the earth's atmosphere is very low, only about 5 parts per million. The output

Quite pitiful.

Fortunately, with the technology of modern time and space, it can be extracted from natural gas. The price is not high. A 22-liter bottle of helium only costs more than 150 yuan online.

, of course, is still much more expensive than hydrogen.

After Intelligent Brain Cortana put information about helium manufacturing on the holographic screen at Li Anran's request, Li Anran discovered depressingly that if he wanted to purchase helium in large quantities, it was actually more cost-effective to buy it from the United States.

.

There is no way, who makes other people's territory so good? The average helium content in natural gas is 1.5%, many can reach 7%, and the highest can even reach an incredible 15%.

The number is enough to make other countries so jealous that they can’t even cry.

What makes Li Anran speechless the most is that, for the same natural gas, most of the helium reserves in his country's gas fields are below 0.2%, and the highest does not exceed 5%. Comparing the two, this Ni

Horses are completely the difference between tall, rich and handsome people and poor ones.

"Wait a minute, Cortana, even if helium can be purchased directly from modern time and space, what about the electromagnetic pulse engine? Isn't this too advanced?" After understanding the problem of helium, he suddenly thought of something

Li Anran said the question.

"Compared to human technology in modern time and space, the electromagnetic pulse engine is not too advanced. This technology has actually been invented, but it is not yet popular because of the size and power of the equipment."

"And based on my penetration into the modern space-time network, the human world is too dependent on the industrial chain formed by the old energy system. Even if there are no problems at the technical level and it can be put into mass production, this technology will not be popularized."

"With the level of technology that the commander has invested in the Tang Dynasty, the electromagnetic pulse engine does not exceed the limit of the corresponding category. 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 Central Intelligence Cortana's answer, Li Anran had to admit that what the other party said was quite reasonable. Although this electromagnetic pulse technology was indeed very advanced, he had no intention of popularizing it in the Tang Dynasty. He just used it for himself.

No problem.

Even if there are some high-level alien civilizations in this time and space, and they also discover the electromagnetic pulse technology they use, I believe they will not be able to follow the clues to see their true combat effectiveness, but it will have a confusing effect.

However, just after Li Anran accidentally clicked on a picture and zoomed in, he saw clearly the six directions of the Yufeng I-type airship: left front, right front, left middle, right middle, left rear, and right rear.

When a certain piece of equipment is installed, I can't help but be a little dumbfounded.

"Cortana, can you explain what these gun barrels are?" Li Anran, who was sure that he was not dazzled, pointed at the pair of objects that appeared to be machine guns after the picture was enlarged.

asked linearly.

"Commander, this is an M2 small-caliber rapid-fire electromagnetic cannon with a caliber of 12.7mm. It can fire 12.7x99mm small-caliber depleted uranium armor-piercing projectiles. It can reach eight times the speed of sound at the fastest, and the rate of fire is between 1,500 and 3,000 rounds per minute.

No wait.”

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

On the holographic projection screen.

"Okay, do you still want to tell me that the technological reserves of this thing have not exceeded the limit?" Li Anran, who was too lazy to look any further, sat back on the master control chair of the entire multi-functional exploration spacecraft, and then asked

road.

"Yes, Commander." Cortana replied calmly.

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

"Yes, Commander, only two people are needed to control the operation of all systems including the flight system and weapon system. Moreover, the cockpit is completely isolated from the cargo compartment, and outsiders cannot enter without authorization." Cortana explained.

"Okay, okay, since you recommended this, then this is it." Li Anran, knowing that the other party was much smarter than him, shrugged and said, "By the way, don't exceed the limit in terms of materials."

"Commander, please rest assured that the materials used in this Yufeng I-type airship do not exceed the limit. However, considering that the demand for airships in the Tang Dynasty cannot be as small as one or two, it is recommended to build one there.

Supporting production lines.”

"I knew it would be like this." Li Anran, who knew that he really had no choice in this matter, said resignedly: "I agreed to this matter. I will postpone the original production sequence and manufacture the equipment for the relevant production lines as soon as possible.

"

"By the way, remember to equip me with enough engineering machinery. Don't expect that there will be enough skilled workers in the Tang Dynasty for you to use. Also, since it is a supporting production line, does helium manufacturing also include it?"

"Yes, Commander." Cortana replied.

"In that case, add a batch of automatic turrets to the production sequence. I don't want my territory to be targeted by irrelevant Tu tribes." Considering that he definitely did not have the time or manpower to manage this production line, Li
Chapter completed!
