Datang: My Peerless Talent Has Been Exposed

In order to ensure that the only remaining excellent scientific researchers of his own will not die halfway due to some minor problems, and at the same time allow them to study the mysteries of the sky and flight more safely in the future, Zhang Nuo spent a lot of money to exchange for a whole set of future generations of hot air balloons Burning device.

With these things in place, the flight safety of the entire hot air balloon has been increased by at least ten times.

It was also after that that the entire Feitian project team basically flew up once or twice. If it weren't for the troublesome fuel replenishment, they would fly up every day to study something.

At this time, they no longer used the fuel given by Zhang Nuo, but kerosene purified through crude oil purification, distillation and other processes as the main fuel.

This thing can be produced only by simple distillation, the preparation difficulty is relatively low, and at the same time, it has better flammability, and more importantly, the freezing point is minus [-] degrees, which is currently the most readily available fuel.

As for gasoline, it is too troublesome to prepare, and it is just a joke without a certain industrial level.

However, the raw materials for this thing are rather troublesome. Zhang Nuo never thought that there is such a natural crude oil lake that can be mined on the surface of Pyongyang Province. The local officials saw that this thing can be burned, but it is very troublesome to burn it in the city of Pyongyang. It was accidentally said as an anecdote during a meeting here.

Zhang Nuo was shocked when he heard about it, and immediately sent people to carry out the most primitive mining, and then transported it to the research institute.

Although Zhang Nuo has no plans to develop an internal combustion engine for the time being, it is still possible to use it for small-scale experiments. After all, the technical reserve is always several levels higher than the existing technology.

Having said that, since Li Shimin and his wife are going to fly to the sky, as the project director here, Xu Bowen naturally has to accompany them.

At the same time, there is another reason, that is, Xu Bowen's grandson has become the most skilled hot air balloon pilot in the entire scientific research institute by taking advantage of his position.

Just because he can control who goes up and who doesn't, he even accepted gifts from many people in private, and brought many people from other project teams up to try the fun of flying into the sky.

Therefore, today's hot air balloon pilot is none other than him.

Now that it's settled, Xu Bowen will arrange for people to start preparations for the flight.

Don't look at the hot air balloon, which is very simple in principle. In terms of parts, there are only a few big and small things, but in fact, it is really troublesome to prepare.

Needless to say, take it out first, and it can’t be placed casually. The entire airbag has to be laid flat on the ground, and at the same time, all the hanging baskets are connected, and the ropes are arranged neatly.

After that, a large blower is used to inflate the airbag. At this time, ordinary air is rushed in, in order to inflate the entire airbag.

Otherwise, if the combustion device is turned on at this time, it will not heat the air, but burn the entire airbag with a fire.

Wait until the entire airbag slowly inflates from a large beach on the ground into a big ball under the action of the blower.

At this time, the fire is about to be ignited. Xu Bowen asked the others to get out of the way and started it himself. First, he slowly heated it with a medium flame, and then waited until the entire airbag gradually floated from the ground, and even pulled the hanging basket upright together, then turned to a small fire. .

At this time, you can go to the master, and put some odds and ends on it at the same time.

For example, the overcoats used to keep out the cold, the small anchors used for landing, and even because the emperor and empress were going up, Xu Bowen took his own initiative and brought some food up.

After all, the wind is not strong today, maybe it will take a long time to float to the port area and land.

At the same time, today Xu Bowen also installed a small soft sail that can be easily manipulated. This thing is still useful in light wind or even calm weather. Under the control of experienced people, it can slightly increase the flying speed.

And when everything is ready, Li Shimin and his wife can come up.

Looking at Xu Bowen, who was already standing in the bamboo basket, adjusting the combustion device, and Xingben, who was standing aside and helping to organize things, Li Shimin looked at the Empress Changsun beside him, feeling a little weak in his legs.

Just kidding, this is not something like riding a horse secretly or climbing over a wall when I was a child. After this guy goes up, if something falls from the sky, then no matter how good your martial arts are, it will be useless, no matter whether you are an emperor or a refugee , All smashed to pieces for you.

However, no matter what, he brought up this matter himself, and his wife was still watching. If Li Shimin suddenly couldn't speak up, he would lose all his face in this life.

So Li Shimin gritted his teeth secretly, took Empress Changsun's hand and walked into the bamboo basket.

Although this bamboo basket is simple, this thing alone is not simple. It has been specially verified, whether it is the material or the weaving method, it has been tested many times.

And the test method is very rough, that is, hang the basket with a rope, and then a few people go up to do Q, only when eight people are crowded inside and do Q for half an hour, can it be proved that it is a qualified bamboo basket.

So one of the four people currently carrying the load is a woman, so there is no need to worry.

After Xu Bowen finished the combustion device, he followed Xingben to sort out the supplies. After making sure that everything was in place, he turned to look at Li Shimin,

"Your Majesty, we can take off now, shall we set off now?"

Li Shimin looked at Empress Changsun beside him, held her little hands silently, then turned his head and said seriously,

"Then take off!"

Chapter 619 The Flying Experience of the Emperor and Empress

The take-off of a hot air balloon is completely different from that of other aircraft in the later generations. It hardly feels any movement. As the burner above the head spews out long flames, a large gust of hot air begins to flow along the airbag. cavity into the hot air balloon.

When the hot air reaches a certain concentration, the buoyancy produced by the entire hot air balloon exceeds its overall mass, and the hot air balloon can fly.

If the whole process is viewed in later generations, it is really slow.

But from Li Shimin and his wife's point of view, not long after they came in, they only saw fire coming out of the top of their heads, and then not long after, the whole bamboo basket shook slightly, and then flew up.

Looking at the gradually widening field of vision and the gradually shrinking houses and streets under his feet, Li Shimin felt inexplicably proud.

Damn, only my empire has such a miracle, and only I can see such a scenery.

Li Shimin hugged Empress Changsun, smiled and pointed to the houses that had become the size of small boxes and Pyongyang City that looked like a sand table, and said with a smile,

"Guanyin maidservant, this time we really didn't come out in vain. This kind of scenery is not something you can usually see in Chang'an City or in the palace, especially if you have to see it more!"

Empress Changsun was also flushed with excitement at this time, looking around like a young girl looking left and right.

No one can resist the temptation to take to the sky and see the world from a perspective they have never seen before.

This temptation is the inherent desire of human beings who have been living on land to measure the earth with their feet. It is a pursuit that emerges every time they look up at the sky.

Now, Li Shimin, the emperor who ruled the Tang Empire, has finally realized his childhood dream. This feeling as if famous mountains and rivers are crawling under his feet can always make people's pride burst out unconsciously.

Li Shimin was like this at this time, looking at the looming coastline and port area in the distance, and seeing the city of Pyongyang under his feet which had become only a small box size, Li Shimin suddenly laughed out loud.
