Starting from 1900, the Wright brothers made a glider with curled wings and flowing rudder in two years, and conducted three gliding experiments successively, measuring wind direction and airflow, recording data, uncovering flight mysteries including sharp turns, inclined taxiing in the air and turning, and repeatedly improving the shape and structure of wings and rudder. 1903, 12, 17 in the early morning, the Wright brothers flew for the fourth time. On the first test flight, the plane flew 37 meters in the air at a speed of 48 kilometers per hour, and the time was 12 seconds. The best time lasted 59 seconds and advanced 260 meters.
However, this flight has become a milestone, marking the successful realization of sustained, dynamic and operable flight. The dream of flying in the blue sky has come true.
I want to study hard, learn my true skills, and learn the tenacious spirit of the Wright brothers who are good at observation and are not afraid of difficulties. When I grow up, I will be an inventor and make some contributions to mankind.
2. Write a composition about the invention of airplanes. Man has always dreamed of flying in the sky like a bird. It is planes that help human beings realize their dream of flying. They fly higher, faster and farther than birds.

3. The invention of the airplane Composition 400 words The invention of the airplane
After several years of painstaking research and development, a multi-functional aircraft was finally designed in 2028. As soon as it appeared at the exhibition, it immediately attracted many eyeballs and was praised by everyone.
The average speed of an airplane is close to the speed of light, it can circle the earth in a few seconds, and it can stop over a certain place like a helicopter. Of course, it can also be adjusted to the same speed as an ordinary plane. To enter the door of the plane, you need to enter a password, and the door is also equipped with a monitoring device, which can identify strangers, even if it is a tiny gap. When you get on the plane, a relaxing concert will be played immediately. There is a temperature adjusting device at the door, which can adjust the temperature in the plane. The computer on the console can go anywhere. According to the distance, it will arrive soon. Across the corridor, the first room is the kitchen. Don't worry if you can't cook. There are many recipes stored in the computer, so you can teach people how to cook by hand. Go on, the second room is the bathroom. The host can book the bath time in advance, and then the computer will heat the hot water and prepare for the bath. The third room is the bedroom. There is a button on the bedside that says "Rest". When it is pressed, the plane will switch to the autopilot state, and all the doors and windows will be closed, leaving only a faint light. Warehouse is invisible, which is divided into food warehouse, daily necessities warehouse, book warehouse, oxygen warehouse and so on. As long as you give instructions to the computer, you can take things out, put them back or get fresh air. The power of the whole plane comes from a small energy gathering board at the top of the plane. It is very powerful, absorbing the heat or light energy of the sun and other stars and converting it into the continuous power of the aircraft through the energy converter. The most important feature of an airplane is that it can overcome gravity if it goes to another planet. People can stay comfortably inside, just like staying in their own homes on earth.
I believe that as long as we study hard now and rely on our own wisdom when we grow up, this kind of plane will be born ahead of time.
The most important invention was that during the summer vacation, my parents and I went to Shanghai.
We went there by plane. It was my first time to fly. I am excited, but I am also nervous. I'm very excited because I've never been on an airplane before, and I'm looking forward to it. Flying at high altitude is really cool. I am very nervous, because some people say that planes will get dizzy when they take off and land. However, the whole journey on the plane was great.
I want to invent an example of an airplane.
1. Everyone has their own dream home. My family and I want to live in
Shanghai. City. It is one of the most beautiful modern cities in the world. My new house is in.
It's near Huangpu River. It's on the first floor. It's not, there are six rooms .. mine.
My favorite is the balcony .. I can read gardening on the balcony .. In the morning, I
You can see busy streets and river boats. Tonight, I have the ability
Appreciate the bright lights on the river bank. There are no armchairs in the corridor.
Living room, a low coffee table and a bookshelf. My new house has no bathroom.
And a big kitchen .. I am very good at cooking. I shared this with my parents.
Apartment .. Our neighbors are very friendly. I am very happy in my dream home.
Fortab.
6. Composition, the plane I want to invent is 400-450 words. The main characteristics of the plane I want to invent are magic and safety! In the future, many special stealth robots and super navigators will be installed on the fuselage, and people can fly planes remotely through advanced equipment such as global satellite system and radar. When the plane breaks down in flight, the stealth robot will immediately repair the plane's failure and let the plane continue to fly safely.
And the plane I want to invent is green. Today's aircraft must rely on special fuel to start. If the plane is short of fuel in the air, it is a troublesome thing, which may lead to the destruction of the plane and the death of people. Future aircraft will no longer use special fuel and install efficient solar cells and wind energy storage on the aircraft. During the day, solar cells are used to drive the aircraft to fly, and the wind energy storage stores the compressed wind energy generated during the flight of the aircraft for the aircraft to start at night. This kind of plane no longer has to worry about "oil" and environmental pollution!
However, this is at least an illusion. If I want to invent this kind of plane, I must study hard and become a scientist in the future to realize it.

9. Invent an airplane according to the wings of a bird, and the composition is all in the blue sky. Birds are flying freely, which is not only beautiful, but hundreds of years ago, scientists were inspired by the principle of birds and invented airplanes.
When the eagle is flying, because it flies high and the air in the high air flows strongly, as long as its wings have a certain angle, it doesn't have to flap like a bird. Learn the angle and strength of the eagle when flying, and invented the glider. Another example is a kite. When a kite is put up, it must first be driven by running, so that it can fly with a fan force in the air like the wings of an eagle. After flying to a certain height, the flow force of the air itself is what we usually call wind, so that the kite will not fall.
In fact, every bird has inspired scientists, and that is the plane.
When a bird is flying, its wings will keep flapping (I mean most birds). When flying in mid-air, the airflow in the air is not very strong. It's like adding force when you flap. Sometimes the airflow in the air will reduce the power. What does that plane have to do with this? When a bird's wings flap, it acts on the air, and in turn, the air reacts on the wings, thus pushing the bird to fly. When a bird flies, its open wings can generate "buoyancy" with the air flow like a kite, making the bird like an eagle. Even if the wings can fly, the plane can fly. The engine under the wing generates thrust and pushes the plane forward. The forward power of the plane makes the wings flow to the air, just like an eagle. When the fan rotates, the wind pushes forward and you can feel the wind. The reason is that the fan blades act on the air. This is the principle of inventing the helicopter. Birds fly like a fan.
Now the plane is like this, isn't the fan page a little warped, the wings of the plane are like this, and the wings of the eagle are like this, so the invention of the plane is all the credit of scientists and eagles (birds).
Since the plane came into being, the problem of going far away has been solved satisfactorily.
