Camouflage clothing was invented by that biomimicry? Examples and information. Be quick! The teacher

Butterflies Colorful butterflies are colorful, such as heavy moon butterfly, brown vein golden spotted butterfly, etc., especially the fluorescent winged butterfly, which is sometimes golden in the sun, sometimes emerald green, and sometimes from purple to blue. Scientists have been able to study the colors of butterflies for military defense. During World War II, the Germans surrounded Leningrad in an attempt to destroy its military targets and other defenses with bombers.

Based on the lack of understanding of camouflage at that time, the Soviet entomologist Schwanvich proposed to cover military facilities with butterfly-like camouflage by using the color of butterflies that are not easy to be found in flowers. Thus, despite the efforts of the Germans, the military base in Leningrad remained unharmed, laying a solid foundation for winning the final victory. According to the same principle, later people also produced camouflage uniforms, which significantly reduced the number of ** in battle.

Due to the continuous change of position of artificial satellites in space, the temperature can change suddenly, and sometimes the temperature difference can be as high as two or three, which seriously affects the normal operation of many instruments. Inspired by the fact that the scales on the butterfly's body will automatically change the angle and adjust the body temperature with the direction of sunlight, the scientists made the temperature control system of the artificial satellite into a shutter style with a large difference in the radiation of the blades and a large difference in heat dissipation capacity, and a temperature-sensitive metal wire is installed in the rotating position of each window, and the opening and closing of the window can be adjusted with the change of temperature, so as to maintain the constant temperature inside the artificial satellite and solve a major problem in the aerospace industry.

It is a camouflage uniform invented using the camouflage of butterflies and chameleons in the forest or elsewhere.

The chameleon can change its color with the surrounding environment, and it can become one body with the environment. Based on this, humans invented camouflage clothing in order to be better hidden.

Camouflage clothing originated in Scotland, and local hunters can deceive their prey and get a higher chance of success by draping cloth strips and ropes on their bodies when hunting, and the specific time is difficult to verify. During World War I, the army had already imitated this practice to confuse the enemy, and in World War II, the German army began to use and simplify it into a camouflage uniform in the modern sense, and the original camouflage uniform evolved into a camouflage for snipers, called "gilly suit".

There's biomimicry, it's butterflies, the kind of colorful butterflies.

An example of biomimicry: a peculiar small gas analyzer has been successfully imitated by a nasty fly. It has been installed in the cockpit of a spacecraft to detect the composition of the gases inside the ship.

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.

Invented based on butterflies. Butterflies hide among flowers and are difficult for people to spot. In fact, animals also have camouflage uniforms, such as sika deer, which is difficult to detect.
