"Your Majesty, today is just a simple test, but I don't want to alarm the Holy Driver!" Chen Xu greeted him with a group of gentlemen.

"Haha, the summer is long and the days are warm, and I am also bored in the palace, I heard that Aiqing experimented with such a novelty on the river beach, and naturally my heart is itching, so I came here to see it!" Qin Shi Huang stepped forward and took Chen Xu's hand and said with a hearty laugh.

Chen Xu shook his head with a wry smile, pointed to the huge glider that was ready to fly and said: "Your Majesty, this is just a whim after the minister was injured last time because of the release of the bamboo kite was torn off the horse......

Chen Xu led Qin Shi Huang around the huge glider, and the design principle and production process were also roughly talked about, but the emperor was full of interest and personally drilled under the belly of the glider to carefully watch the manned position, and then stroked his palm and said with a smile: "It's okay, Aiqing always has a lot of whimsical ideas, it is rumored that the bamboo kite was invented by the former Lu master craftsman, and the bamboo kite can be made around the beam for three days without falling, although the rumors are difficult to distinguish between true and false, but the bamboo kite can indeed fly very high, The glider designed by Aiqing is so huge, it will definitely be able to fly with wings in the wind, and I am looking forward to it, whether Aiqing can start the test flight! ”

"Your Majesty, everything is ready, please stay away from ten zhang away, and let the rider prepare for the test!"

"Okay, Aiqing arrange it quickly!" Qin Shi Huang left more than ten zhang under the escort of a group of Xuanwu guards, and at this time, the crowd outside the entire east gate surged with flags and waves, and the forbidden army and onlookers were no less than a very large Shangsi Festival festival, which was very lively.

There were more crowds of people pouring out of the east gate, mixed with many two-horse and four-horse cars, obviously also heard that the emperor had gone out of the city to join in the fun, princes and princes and civil officials, even Li Simengyi, Feng Quji, Li Xinmengtian, etc., were among them, and after getting out of the car, they all gathered around the emperor and pointed at the glider.

"Brother-in-law, I'm so worried!"

Meng Yun's excitement and excitement at this time turned into a hurry and uneasiness, looking at Meng Yi's gaze standing beside the emperor and pulling his beard and glaring at him, he felt that his little heart was beating wildly, and his handsome and pretty face had begun to change color slightly.

"What's the use of being worried, it's already like this, you can only bite the bullet, it's a big deal to be beaten!" The other gentleman seemed to be in a much more stable state, but he could see that his twin strands were trembling slightly, and his soul had obviously begun to tremble, not as tough as he said.

Chen Xu twitched a few times and raised his hand, as the two riders signaled, the two riders who had dismounted hurriedly turned over and got on the horse again, and several apprentices who made gliders walked to both sides of the glider to hold it steady.

"The test flight begins~" Chen Xu's hand waved down.

"Driving~~" The two riders smacked the stirrups at the same time, and the two horses ran forward slowly almost at the same time, and the rope that was pulled was soon tightened, and the glider, which had been parked on the grass, began to slide forward slowly, and began to jolt forward slightly on the not so flat grass.

The two horses ran faster and faster, and the glider followed suit, and a group of apprentice craftsmen who were holding the glider could no longer keep up and were thrown down.

Tens of thousands of people on the river beach all looked at the glider that was being led away by two horses without blinking, and opened their mouths wide one by one.

Thirty zhang ...... Forty zhang ...... Fifty zhang ......

As the sound of the ride grew farther and farther away, the whip swung faster and faster, and the two horses finally reached their top speed, and the bumpy and rocking glider began to puff up the sheepskin of its wings under the tremendous speed of traction and the oncoming river wind, and then the nose slowly began to lift up.

"Look, it's flying~"

As countless exclamations sounded, the wheels of the glider, which had a wingspan of several feet, began to leave the ground, swaying from side to side in the wind and slowly lifting, although they were dozens of feet away, it could be clearly seen that the three wheels had indeed left the ground.

"Wow~~" The crowd stirred violently like boiling water.

More than an hour has passed since Meng Yun and others transported the bamboo kite to the river beach, and the people who watched the excitement had already known by word of mouth the purpose of this huge bamboo kite experiment, that is, manned flight.

Although the first test flight did not carry people, a piece of wood about the size of a real person was tied under the bamboo kite, and as long as the bamboo kite could fly, then there would definitely be no problem with carrying people.

Seventy zhang ...... Eighty zhang ......

Under the traction of the two horses galloping forward, the glider left the ground higher and higher in the swing, and everyone could clearly see that the huge glider had flown up more than the height of the two horses, and was still rising, and after reaching a hundred zhang away, the glider had left the ground more than ten zhang to reach the height of the city wall, like a giant bird gliding in the air, although the flight was not stable and swayed left and right, but it was not planted under the traction of the rope.

"Hahahaha, we made it!"

A group of gentlemen excitedly high-fived and cheered each other, and even Meng Yun was overjoyed and hugged Chen Xu's shoulders tightly and shook vigorously, "Haha, brother-in-law, the glider test has been successful!" ”

Chen Xu finally breathed a sigh of relief at this time.

The structure of this delta wing glider is simple, in fact, it is an enlarged version of a huge kite, but it is only manufactured with the technology of making bamboo kites, the body size is large enough, and the wingspan area is large enough, as long as the design is not too asymmetrical, it should not be a big problem to fly in the wind, because these craftsmen are skilled craftsmen who are proficient in making bamboo kites, and have enough design experience, but there is no sufficient aerodynamic theory.

And as long as it can fly, so many tests to observe the flight state several times, and after some fine-tuning, a glider that can really carry people can be born.

Chen Xu did not understand how high and far the glider of later generations could fly, but the glider relied on the airflow flight like the bird, the wind was strong and the airflow was stable, the higher and farther it could fly, so the glider flight had great requirements for the terrain and landform, it was summer now, the weather was sunny and the wind by the river was strong enough, but the terrain was not very good, there was no mountain peak nearby, and a huge airflow lifting effect could not be formed, so it could only rely on the speed of the horse to form enough traction lift, according to the current situation, If the glider can fly 20 zhang, it can easily cross the widest part of the Xianyang section of the Wei River.

As the glider flew higher and higher, the river beach was thunderous, Chen Xu also walked to the emperor's side and a circle of princes and princes smiled and saluted and said: "Your Majesty, these bamboo and wood craftsmen are highly skilled, I didn't expect to be able to leap up in the first test, if there is no speculation from the ministers, there is no big problem for this glider to carry people to fly over the Wei River easily, if it is carefully designed and adjusted, the terrain and wind are suitable, it is enough to carry people to fly hundreds of feet and glide for miles or even ten miles......"

"Wow~" A group of civil and military officials in Chinese costumes all stirred.

"Qinghe Hou, since the test flight was successful, why don't you let people take a test flight and see if they can fly to the other side of the Wei River!" A military general wearing a brocade robe and a military crown stood up, but it was Li Xin, the Marquis of Di Dao.

Chen Xu glared at Li Xin, and then said with a smile: "Although the test flight was successful, there was shaking in the flight, which means that it is not completely in the state of manned flight, and if one accidentally falls into the river, the driver may fall into the water and die!" ”

"I'm afraid of falling into the water, just find someone who is skilled in water!" Another minister shouted.

"Yes, yes, the Wei River is not more than a hundred zhang wide, and the boats in the river are constantly going back and forth, so if you fall into the water, you can naturally be rescued......"

"Why don't you need a boat, you can easily swim ashore!"

A group of princes and princes began to urge.

"Master Hou, I am willing to try the glider myself!" A gentleman who followed behind Chen Xu jumped out excitedly.

"I'm willing to give it a try!" Although a group of gentlemen were afraid of their respective father's angry eyes, almost all of them stood up and asked for their lives.

Qin Shi Huang was very happy, stroked his beard and nodded with a smile and said: "Sure enough, it is my Great Qin Hao Erlang, brave and fearless, I am accurate, I will test fly by the San Lang of the Gaonei Historian, if it is successful, I will be rewarded with two levels!" ”

"Thank you, Your Majesty!" The first one to stand up excitedly took off his coat and threw it on the ground and began to roll up his sleeves.

Chen Xu stopped talking with black lines on his head.

At this time, the glider pulled by two horses has reached two hundred zhang away, there are large and small rocks in front of it, the speed of the horses has slowed down, and the glider that flew up more than twenty zhang lost traction, and began to sway forward like a bamboo kite and began to slide forward and land, and the two riders were also very experienced, and at the same time began to turn, while the glider was still in the air and ran back, the glider followed the U-turn and then did not have a huge wind lift, so it also flew lower and lower, When it was still a hundred feet away from the take-off position, it staggered and slammed into the ground, bounced violently a few times, and finally came to a staggered stop.

A group of bamboo craftsmen and helpers rushed up, untied the rope and carried the glider back, and then began to carefully inspect the damage, reinforcing where it should be reinforced, and retying it up where it should be tightened.

Chen Xu also went up with a group of gentlemen to watch, and waited for a few craftsmen to check and repair, and then carefully told the third child of the Gao family: "Remember not to lie on the wooden frame and do not move violently, hold the crossbar with both hands to control the turning of the glider and adjust the flight attitude through the tilt of the body, don't panic when landing, if the glider loses control and falls into the river, it is the best, if it hangs on the tree and hits the boulder, you will ask for more blessings......"

"Hehe, Hou Ye rest assured, a certain person has thick skin and rough meat, and he is very durable, and he will definitely fly across the river, and this two-level meritorious lord has been decided!" Gao Laosan couldn't wait to get under the glider and lie on the wooden frame, not caring about the consequences of falling.

"Hmph, be careful of falling with a blue nose and swollen face!" The other gentleman who did not get the identity of the first flight was very dissatisfied.

"How can you have a blue nose and swollen face, it must be a broken leg ......" another sour add.

"I'm worried that Saburo's life will not be guaranteed......"

"Silence!" Chen Xu couldn't help frowning and snorted coldly, and at the same time, his head was full of black lines and he didn't know how to speak.

A group of two realistic people are hopeless and will die sooner or later on eating, drinking, and having fun.

Chen Xu even began to regret that he shouldn't have told Meng Yun about the glider in the first place.

Looking at the minds of this group of gentlemen, they will inevitably personally fly the glider to test and play in the future, and the so-called night road will inevitably encounter ghosts.

It's all too normal to die in such a dangerous sport.

And at that time, he will inevitably be hated by these people's families.

Lao Tzu is really troublesome!

Chen Xu muttered to himself, and after seeing that the traction rope was ready again, he twitched and retreated with a group of gentlemen.

Soon the two riders started again, and the glider slowly jolted and began to move forward.
