Scientists have invented new airplanes from flying insects

That's a lot. Flies are the spreaders of germs, and everyone hates them. However, the wings of flies (also known as balance sticks) are "natural navigators", and people imitate them to make "vibrating gyroscopes".

This instrument is already being used in rockets and high-speed aircraft, and it has achieved autonomous driving.

Dragonfly Dragonflies vibrate with their wings to create locally unstable air currents that are different from the surrounding atmosphere, and use the vortices created by the air currents to raise themselves. Dragonflies can soar with very little thrust and can fly not only forward, but also backward and left and right, and can fly forward at speeds of up to 72 km/h. In addition, dragonflies have a simple flight behavior, relying on only two pairs of wings to flap constantly.

Scientists have successfully developed a helicopter based on this structural basis. When flying at high speed, the aircraft often causes violent vibrations, and sometimes even breaks the wings and causes plane crashes. Dragonflies rely on weighted wings to fly at high speeds, so people imitate dragonflies by adding counterweights to the wings of the aircraft to solve the thorny problem of vibrations caused by high-speed flight.

In order to study the aerodynamics of gliding flights and collisions and the efficiency of their flight, a four-bladed, remote-level-controlled model of the locomotive wing (wing) was developed and, for the first time, flight parameters were tested in a wind tunnel.

The second model tried to install a wing that flew at a faster frequency, reaching a speed of 18 vibrations per second. Characteristically, this model uses a device that variably adjusts the difference between the front and rear pairs of wings.

The central and long-term goal of the research is to study the performance of aircraft driven by "wings" and the efficiency of aircraft compared to conventional propeller-driven aircraft.

I only know that *** is based on the flight characteristics of dragonflies, which is a very classic case. The other planes are basically jet-type, which does not seem to fit the flight characteristics of any kind of insect.

1. Birds. 2. One of the most important inventions of the twentieth century was the birth of the airplane. Since ancient times, humans have dreamed of flying and laughing 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 International Federation of Hunger and Aviation (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.

3. 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 ascension and return before conquering the blue sky.

At the end of each dragonfly's wings, there is a thicker spot that is slightly heavier than the surrounding area. This is the key to preventing the wings from trembling (anti-flutter structure).

The dragonfly's wings are thin and brittle, but why doesn't it shake violently and shatter when it flies fast? Scientists have found that at the end of each dragonfly's wing, there is a thick spot that is slightly heavier than the surrounding area. This is the key to preventing the wings from trembling (anti-flutter structure).

Scientists improved the wing in this way, and sure enough, the wing stopped shaking. Later, scientists also paid attention to studying the flight methods and principles of flies, mosquitoes, bees, and other insects, and built many new airplanes with a variety of excellent performance, which played a great role in military, scientific, technological, and civilian use.

Human beings have found and imitated the "magic weapon" of dragonfly wings, and transformed the wings, which is to adopt the method of imitation and invention. The method of imitation invention is a method that takes a certain object as the prototype and learns and draws on it in combination with reality, so as to lead to innovative ideas.
