Since ancient times, human beings have always had a strong yearning for the sky. Because of their religious beliefs, they believe that the sky is where God lives. However, due to the backward science and technology in ancient times, flying is definitely impossible.
I don’t know how many people have tried to fly into the sky.
However, they all ended in failure.
Therefore, Liu Zheng's words immediately excited the three of them.
"Sir...can this thing go to heaven?"
"Can it fly?"
"Isn't it possible? This..."
Although I know that my son is very powerful, he can fly to the sky! Many capable people in history have not been able to do it, but Liu Zheng can do it?
Liu Zheng chuckled.
It is true that he cannot make any airplanes, rockets, or aircrafts now. But as he is deeply influenced by the science and technology of later generations, he still has no problem tinkering with a hang glider.
This was something that suddenly popped into his head these past few days while he was eating melons, watching movies, and fishing.
Why?
It's very simple, it's aimed at the Huns!
Liu Zheng thought for a long time, why the ancient Xiongnu soldiers were so difficult to deal with, it was because they were too mobile. They could fight and retreat, so they were very difficult to deal with.
So what is the solution to deal with the Huns?
In history, it is actually recorded. It is mentioned in the "Book of Han" that Wang Mang recruited strange people from the people and developed a method to make wings from bird songs, put feathers on the head and body, and fly up from the ground with his feet.
, it really had to fly hundreds of steps before landing. This should be the predecessor of wingsuit flight.
At that time, Wang Mang wanted to attack the Xiongnu!
Of course, regarding flying, in the early Ming Dynasty, there was a man named Tao Chengdao, holding two kites, sitting on a snake-shaped flying car with forty-seven rockets attached, and flew into the sky through the reaction force of the rockets. Unfortunately,
The unfortunate fall is the story of "Ten Thousand Houses Flying to the Sky".
When Liu Zheng admires these pioneers, he will naturally not put himself in danger...
What he wants to do is hang gliding!
This is what he has been tinkering with these days.
Gliding is the only way he can achieve flight in this era. The main structure of a hang glider consists of a triangular frame, a control frame, a mast, tension lines, and umbrella cloth.
The triangular frame is composed of a keel, a beam, and two leading edge beams, which determines the plane shape and area of the umbrella wing.
The initial triangular frame was on a plane, and the keel was as long as the front edge. Later, it gradually developed, the angle of the vertex gradually became larger, and the keel became relatively smaller and curved.
Since Liu Zheng had scientific knowledge, he naturally went straight for the perfect one! He controlled the weight of the hang glider between ten and thirty kilograms, with the center of gravity slightly forward. Of course, he also needed many test flights to determine the most suitable size and
angle.
Near the end of the leading edge, the outer wash strut is also fixed. The first function is to prevent the wings from stalling at the same time, and the second is to automatically improve during the dive.
The control frame is also an equilateral triangular frame made of three rods. It is fixed under the keel and beam and is used by the pilot to control the direction. Nowadays, two wheels are usually installed on the bottom rod of the control frame.
The mast, fixed above the keel, is used to support all landing tension lines and prevent the wings from bending when overloaded.
The tension line on the upper surface of the umbrella wing is called the landing tension line, which is connected from the main mast to the top corner, leading edge, and keel. Its function is to land or bear the weight of the wing on the ground.
The tension line on the upper surface of the umbrella wing is called the lift tension line, which is connected from the two ends of the control frame to the top corner, leading edge, and keel. Its function is to bear the tensile force during flight; there is also a reverse bending tension line on the upper surface of the umbrella wing.
The ribs connected from the main mast to the umbrella cloth are used to make the airfoil a little counter-bent to ensure that the glider can recover from a dive.
Umbrella cloth: The skin of the hang glider is sewn on the triangular frame. There are also certain long pockets sewn on the two wings, with ribs inserted inside to maintain the shape of the wing.
certainly......
In the future, Liu Zheng will also develop some equipment for pilots to protect their safety.
But currently, this hang glider is still in the testing stage, and those are things for the future.
