How airplanes are made, how airplanes are made

Here's how to make an airplane:

1. Cut the paper according to the drawing.

2. Paint your favorite pattern.

3. Assemble the paper-cutting.

A beautiful airplane is made! Handicraft can improve concentration, fine motor skills, hand-eye coordination, and innovative thinking.

Fixed-wing aircraft refers to an aircraft with wings, one or more engines, propelled by its own power, and can have a density greater than air in the atmosphere. If the density of the aircraft is less than air, then it is a balloon or an airship. If there is no power unit and can only glide in the air, it is called a glider.

If the wing of the aircraft is not fixed, it is a rotorcraft that generates lift by wing rotation. Fixed-wing aircraft are the most common aircraft type. Power** includes piston engines, turboprops, turbofan engines or rocket engines, among others.

At the beginning of the 20th century, the Wright brothers of the United States made significant contributions to the history of aircraft development in the world. In 1903, the first manned flight under its own power, the "Flyer I", was built and successfully tested. They were awarded the U.S. Congressional Honor Award in 1909.

In the same year, they founded the "Wright Aircraft Company". Since the invention of airplanes, airplanes have increasingly become an indispensable means of transportation for modern civilization. It profoundly changed and affected people's lives, and opened the history of people's conquest of the blue sky.

**To date, with the exception of a few special forms of aircraft, most aircraft consist of five main parts: wing, fuselage, tail, landing gear, and power plant.

To understand the principle of aircraft take-off, we must first know a basic principle in fluid mechanics: flow velocity is inversely proportional to pressure. That is, the faster the air moves, the less pressure the air will be, and vice versa.

We can do a famous simple experiment: take a piece of paper in each hand, hold it at a certain distance in front of your mouth, and blow gently in front of the two pieces of paper, and you will find that the two pieces of paper are not blown open by you, but by you. Because the air between the two papers flows, the pressure becomes smaller, and the air on the outer side of the two papers does not flow, and the pressure increases relatively, and the paper is "pressed" by the air.

Well, knowing this principle of fluid mechanics, it is easy to understand the take-off of an airplane.

Let's take a look at the wing structure of an airplane. It turns out that the shape of the upper and lower sides of the wings of the aircraft is different, the upper side is more convex, and the lower side is flatter. When an airplane taxi, the wings move in the air, which is equivalent to the air flowing along the wings in terms of relative motion.

Because the shape of the upper and lower sides of the wing is different, the air on the upper side of the wing flows more distance than the air on the lower side (the curve is longer than the straight line) in the same amount of time, that is, the air on the upper side of the wing flows faster than the air on the lower side. According to the principle of hydrodynamics, when the aircraft slides, the air pressure on the upper side of the wing is less than that on the lower side, which causes the aircraft to produce an upward buoyant force. When the plane taxith to a certain speed, this buoyancy reaches a force strong enough to make the plane fly.

So, the plane went into the sky.

This is how airplanes take off.

On December 17, 1903, the "Flyer" designed and manufactured by the brothers Wilbur Wright and Orville Wright of the United States successfully flew in Kitty Hawk, Carolina, which was recognized as the world's first maneuverable manned power aircraft to fly into the sky.

How to make an airplane by yourself, it is necessary to consider the problem of the site, although the fixed-wing aircraft is simple to manufacture, but the take-off and landing need to be carried out on the runway. There is no place to fly after it is built, so I suggest that it is better to build ***.

Let me teach you how to design ***: The common forms of light *** are coaxial and single-rotor with tail rotor. Due to the complex structure of the coaxial form, into 1 ton, it belongs to the light weight, so the form of single rotor with tail rotor is adopted, from the engineering practice, the form is relatively mature, and the cost is also low.

The total weight of the *** is less than 500kg, which belongs to ultra-light*** 1) Paddle load The paddle load mainly affects the hovering ceiling, vertical climb speed, use ceiling, maximum climb speed performance, etc.

The aircraft is made of aluminum alloy, and the aircraft is made of the nose, fuselage 1, fuselage 2, tail, tail, rudder, wing, and engine. The seats in the aircraft are all manufactured according to the requirements of the airline.

The oldest airplanes are also very complicated things, they have to have engines, fuselage wings, tail flaps, and landing gear, which is very difficult to do, but in the people, there are indeed many college students, ordinary workers, and farmers who have successfully made local airplanes and flown into the blue sky.

In 1986, Cao Zhengshu of Yongle County, Mianyang, Sichuan Province, manufactured an airplane and flew it many times, but it was unsuccessful.

In 1991, Liu Yibing, a farmer in Beita Village, Honghua Township, a suburb of Yinchuan City, Ningxia, built his first airplane. It flew for 51 minutes at an altitude of 100 meters, including 6 tandem flights with his mother and friend.

In 1995, Song Mingwu, a farmer in Linyi, Shandong Province, built an airplane after five years, but failed to test it many times.

In 1996, Zhang Dousan, a farmer in Chaozhou, Guangdong, successfully built the aircraft "Douqiang No. 3" on his rooftop and participated in the Zhuhai Air Show twice. Known as the "machine maniac".

On May 1, 2001, the first test flight of an airplane manufactured by Su Daocheng, a farmer in Yunxi County, Hubei Province, ended in failure.

In 2002, the test flight of the "Gansu Shenlong" aircraft manufactured by Bai Zhongjin, a farmer in Pingchuan District, ** City, Gansu Province, failed. Now the plane has become a "three-wheeled car".

In 2003, Zhang Yuxiang, a farmer in Pingchuan District, ** City, Gansu Province, manufactured an airplane and failed to test it many times.

In 2003, Yue Xinglin, who worked at the University of Science and Technology of China, built an airplane that caught fire before a test flight.

In 2003, Wu Zheng, a citizen of Nanjing, spent 13 years building an airplane, and the results of the test flight were unknown.

In 2004, Li Juncheng, a veteran, built an airplane, and the results of the test flight are unknown.

At 3:40 p.m. on July 8, 2006, Xu Bin put on a motorcycle helmet, turned the rotor with his hand and got into the plane, and under the traction of the car, the plane glided 150 meters on the ground from slow to fast, and finally flew into the blue sky. The plane carried him to soar in the blue sky for 25 minutes, setting a precedent for Zhejiang Province's self-built aircraft to carry people into the sky.

On August 16, 2005, Tan Chengcheng, a farmer in Kuiwen District, Weifang City, Shandong Province, flew into the blue sky with a self-made airplane. Tan Chengcheng is 48 years old this year, he has loved airplanes since he was a child, and seven years ago he borrowed relevant books to develop his own airplanes, but he made two planes and did not fly. Last year, he spent 10,000 yuan to learn a pilot certificate and began to modify and build a third aircraft, which was finally successful.

Tan Adult flew at an altitude of between 150 and 200 meters, and the flight time reached 20 minutes.

On August 18, 2005, Tan Chengcheng, a farmer in Kuiwen District, Weifang City, Shandong Province, gave his wife Li Yufeng a special birthday gift——— piloted a plane made by himself to take his wife to the sky for a 30-minute tour.

First of all, enter the sandbox mode, and then you will see that there is a plus button on the right side of the screen, click it, and the inventory will pop up on the left side, and then build the fuselage first, and then adjust the fuel to the maximum in the settings of the fuselage, and then install the engine on the fuselage, it is recommended that you use propellers to save fuel. Then there is an inventory of wings, and after the wings are installed, you can put ** on the plane, ** a lot, machine guns, missiles and everything.

Wait until you're in your right mind.

Here's how to make an airplane:Prepare materials: paper.

Operation steps: 1. A rectangular piece of paper is allowed.

2. Fold the paper in half along the longer side.

3. After folding in half, fold the two corners on both sides to the middle crease.

<>5. Finally, pinch the middle of the paper airplane and sort it out, and the paper airplane will be formed.

The practice of the aircraft is as follows:

Tools Raw materials: mineral water bottles, paper skin, adhesive tape.

1. Cut two openings on both sides of the mineral water bottle with a utility knife. The carton board is cut into the shape of a wing, inserted into the opening, and secured with scotch tape.

2. Cut 2 more cardboard boards to make the shape of the tail wing, and then wrap the 2 cardboard boards with red tape and fix them together.

3. Cut the toilet paper tube into 2 equal sections, cut a few notches at the opening of each section and then fold it inward, and fix it with scotch tape to make it into a cup shape.

4. Cut the popsicle sticks into 2 sections. At the bottom of each "toilet paper tube", glue 3 sticks respectively, and the angle between the popsicle sticks should be about the same, making it into an airplane engine.

5. Decorate the body with plastic tapes of different colors.

6. Cut one side of the engine, insert it at the end of the wing, and use transparent tape to fix the engine and wing together.

7. Fix the engine on the other side of the aircraft in the same way.

8. Wrap the propeller into different colors with tape.

9. Then cut the middle above the tail of the fuselage, insert the tail fin, and fix it with tape.

10. Finally, use markers and stickers to simply decorate Xiangzhou.
