There is no mechanical power device on the glider.
The reason why it can fly for a long distance in the sky is purely by using the buoyancy and flow of the air.
The wind principle is basically the same as that of a sailboat floating on the water, but it is more complicated and involves air.
Dynamic meteorology and many other aspects of knowledge. Although the appearance of the glider has wings, fuselage, tail and rudder, it is quite different from ordinary aircraft. The wings are relatively long. In terms of manufacturing and designing glider, the wingspan is large. The reason why this sport cannot be popularized is not that there are few people who like it, but that it costs a lot to make a good glider.
It needs to use light but strong special wood, which is expensive and has a large open space for the glider to take off.
A glider cannot take off by itself.
It has to be pulled up by a high-speed car or a small plane.
The situation is similar to flying a kite, except that someone on board controls the flight along the airflow. The control of the glider is almost entirely determined by the airflow. The driver cannot resist the airflow. Can only use air currents to fly.
A lot of things have been said about large manned gliders. It seems very ordinary, not like the beginning of a novel. In fact, there are many weird and thrilling things.
Maybe the beginning is not at all ordinary.
For example, what kind of excitement does the following picture make people feel? The word picture is used in an attempt to use words to create an impression in the reader’s mind as if seeing a picture. Please just look at it as a picture.
It is still, just like looking at a photo. It is a rather spacious living room. The living room is different from the living room. When the living environment was not so bad, there was a living room in the house, which was used for family members to gather, rest and chat. It is not dedicated to entertaining guests. Of course, if it is a friend who is particularly familiar with this family, you can also chat with the owner in the living room. The living room layout is quite elegant, harmonious and noble.
You can tell at a glance that the owner is an intellectual with rich knowledge and high taste.
Light beige color The carpet is close to the pure white sofa. On the wall, there are strips of oracle bone inscriptions and light ink landscape characters. The color tone of the whole living room is so soft, so there is one thing that should not belong to such a living room.
Although it is placed in a corner It is already a place that is as inconspicuous as possible, but because it really does not match the rest of the furnishings in the room, anyone can still see it at a glance, and can’t help but frown when they see it. At this time, there is a The young man frowned in front of that thing. What is that thing? In fact, it is very common. It is not a rare object, nor is it something strange and scary. It is just a model of a glider. That model. The wingspan is about one meter long, because the fuselage of the general glider is designed to be shorter than the wings, this model is no exception.
The model is very beautifully made. The nose is slightly upward, showing that it is rising along the rising airflow. The whole model fixed on a bracket the height of the bracket A model that reaches the chest of an ordinary person is naturally not suitable in a room dedicated to young people, but it is placed in such an elegant living room full of cultural atmosphere, and it is right next to the model of the glider. There’s an easy chair next to it that looks pretty old and it’s sitting right next to the brackets which looks odd because the brackets block the chair and if anyone wants to sit in the easy chair it’s going to have to be a lot of work.
The bracket and the model can be removed together to achieve the purpose.
A chair is placed in such a way that the only purpose seems to be that one does not want people to sit on this chair, but if it is not for people to sit on this chair, why put a chair in it? There, the glider competition looks a bit weird, isn’t it that the young man standing in front of the glider model is tall and handsome, he has a long beard and holds a pipe in his hand, with a few strands of smoke coming out of the pipe His clothes are very casual, but he looks very comfortable.
He has quite thick eyebrows and an almost stubborn look in his eyes. If a person who is interested in archaeological exploration can know him as soon as he sees this bearded young man Who is this young man? Although he is only twenty-seven years old, he is already an excellent explorer. The National Geographic magazine of the United States has published three special issues for him in a row, praising his achievements in the exploration work in the jungles of Honduras in Central America, and he was in Guiana in northern South America. The achievements of the exploration work in the area are also extremely charming. This young man’s name is Lotte.
Not far from Lotte, there is a middle-aged man sitting on a sofa. The age of men is sometimes more difficult to estimate than women.
The age of the middle-aged man can be said to be between 40 and 60 years old. He is wearing a white silk short Chinese dress and looks elegant and youthful. This middle-aged man is actually close to 60 years old. His appearance just shows his profession.
He is a university professor, Yueqing, and his achievements in ancient literature of various countries are admired all over the world.
There are many words that are no longer applicable in the world. Only a few people can recognize those words. Among the few people, Yueqing and Professor Yueqing must be one of them.
To give an example, there is a kind of writing that appeared in China in the year of AD and has been used for more than a hundred years. It is forgotten on the cultural stage that there are no more than four people in the world who can understand Khitan characters. Of course Yueqing and professor are one of them, and the other three people are his students. Professor Le and his son Letian stand side by side. together
