Airplanes are a common means of transportation, and what kind of animal was inspired by the inventio

Humans have been living on earth since they were born. Mountains and seas have hindered communication between people for a long time, and we have always longed to overcome this obstacle one day. We are familiar with "Gong Yu."

The story of "moving mountains" actually reflects from a certain angle how much the terrain has brought to people's travel in the past. Today, although we essentially have the ability to "move mountains and reclaim the sea", we have developed many highways and high-speed railways.

However, there are certain obstacles and limitations in both land and sea traffic, and the speed cannot reach such a high level. At this time, air freight is required. The invention of the airplane was undoubtedly a major event in the history of mankind. At the beginning of the 20th century, the Wright brothers.

Inspired by the wings of birds, a vehicle that could soar through the sky was invented.

i.e. airplanes. Airplanes allow humans to see the infinite possibilities above the sky and see another uncultivated field.

Under the leadership of the Wright brothers, people began to invest countless manpower and material resources in the development of airplanes as a means of transportation. In just a few decades, aircraft have become a tool and occupy a very important place in both civilian and military applications. to the Second World War.

, aircraft have become the main force of the army. More than 70 years have passed since the end of the Second World War. Nowadays, civil aircraft have become a more popular way to travel.

Larger cities have their own airports, and airplanes are still the most time-saving option for long-haul travel. In the military aspect, the status of aircraft is much higher than in those days, and countries want to get more advanced fighters to improve their military power. It is conceivable that in the future aircraft will become more advanced, and perhaps the cost of using it will be further reduced, making it easier and cheaper for us to travel by air.

More than half a century after the invention of the airplane, mankind has once again made a breakthrough in the matter of "heaven" and broke through the atmosphere.

and part of the gravitational constraints, to the boundless universe. It is another means of transportation - rockets that help humans accomplish this feat.

In ancient times, people began to use rocket-like firearms, but people at that time would not have imagined that one day this tool could take people to the distant moon and fulfill their long-cherished wish for thousands of years. Nowadays, people's space technology is becoming more and more advanced, and we can stay in space for longer periods of time and go farther. However, while rejoicing in the development of human science and technology, we will also think about a question:

Airplanes and rockets are both vehicles capable of going to the sky, while airplanes were invented earlier and took a longer time to develop.

Birds. Some people saw that birds could fly freely in the sky, and these animals had wings, so they invented airplanes.

The invention of the airplane was inspired by the animal of birds, as birds could soar freely in the sky.

The invention of airplanes was inspired by birds and animals, so I think the Wright brothers are very powerful.

Airplanes were invented based on birds.

One of the most significant inventions of the twentieth century was the birth of the airplane. Since ancient times, humans have dreamed of flying in space like birds. The airplane is recognized as having been invented by the American Wright brothers.

Their flight on December 17, 1903, was recognized by the Fédération Internationale de Nautical (FAI) as "the first controlled, sustained powered flight of a heavier-than-air aircraft", and 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.

Take-off and landing

The take-off of an airplane depends on the lift generated by the relative motion with the air, and the magnitude of the lift depends on the relative speed of the aircraft with the air, not the relative speed of the aircraft with the ground. If taking off against a headwind, the aircraft taxiing speed is opposite to the direction of the wind speed, and the relative velocity of the aircraft and the air is equal to the sum of the two. At this point, the aircraft only needs a small glide speed to get the lift it needs to get off the ground.

As a result, the distance required to take off against the wind will be shorter than if it were to take off without wind. Conversely, if taking off downwind, the aircraft needs to reach a higher taxiing speed to get the lift required from the ground, and the glide distance is relatively longer.

What are some things that humans have invented based on a certain characteristic of animals?

There are rewards to write a total of 16.

With you the first 12

Let's talk about following to become the 421st fan.

1.The eye of the fly, the fly's eye camera was invented.

2.The sensitivity of flies led to the invention of hazard detectors, which were used in dangerous workplaces.

3.The gliding skills of the eagle, the invention of the glider.

4.The shape of the bird's line changes the shape of the aircraft and is more aerodynamic.

5.The bones of birds, which have improved the skeleton structure of the aircraft, are lighter and stronger.

6.Acoustic detection of bats and dolphins, the invention of ultrasonic radar.

7.Airplanes flying at night on radar are the inspiration people take from bats.

Additional Information:1Whale: The shape is an ideal "streamliner", and the "streamliner" has the least resistance in the water. Later, engineers imitated (fǎng) the shape of the whale and improved the design of the hull, which greatly increased the speed of the ship.

2.Eggshell: Able to evenly distribute the pressure (yún) to all parts of the eggshell. Based on the characteristics of this "thin shell structure", the architect designed many buildings that were both light and economical.

3.Kangaroo: An off-road vehicle that can jump.

4.Shell: A tank with a sturdy shell.

5.According to the chameleon's principle of color-changing, military uniforms that can change color depending on the environment were invented.

6.Pigs would stick their noses into the soil to filter poisonous gases when they encountered poisonous gases, and people invented gas masks.

The emergence of airplanes is undoubtedly from people's direct imitation of birds, and the realization of many functions such as vertical take-off and landing of modern aircraft, and U-turn after fixed suspension in the air is also deeply inspired by birds and mosquitoes.

Boats and submarines come from the imitation of fish and dolphins, and biologists have studied spider silk to create high-grade silk threads, tear-resistant parachutes, and high-strength cables for makeshift suspension bridges.

The Sidewinder missile is a modernization developed by scientists imitating the snake's "hot eye" function and the principle that its tongue is arranged with a natural infrared perception ability similar to a camera device.

Biomimicists were inspired by the ability of ants, bees and other animals to use polarized light to orient themselves and create polarized astronomical compasses for navigation and aviation.
