How do bees fly?

Spontaneous intellectuals - the concept of God, not evolution, have created complex life forms - long ago criticized the scientific world for not being able to interpret even some natural phenomena. , like a bee fly. Now, science has deciphered that mystery.

Honeybees flap their wings so fast, it is difficult to study their movements

Using a combination of high-speed digital cameras and a bee-wing robot model, researchers discovered the flight mechanism of honey bees.

For years, people have tried to understand the flight behavior of animals based on the aerodynamic mechanisms of aircraft and helicopters, said Douglas Altshuler, a researcher at the California Institute of Technology."In the last 10 years, biologists have gained a significant amount of knowledge by doing experiments with robots capable of flapping wings freely like animals."

Scientists analyzed images obtained from hours of video footage of bees and used robots to mimic their movements, with sensors to measure force.

Analysis shows that bee's flight mechanism is more exotic than previously thought.

"Honey bees flap their wings very quickly," Altshuler said. "The tiny fruit fly and smashes its wings 200 times per second. The honey bee has a larger body size up to 80 times to flap its wings up to 230 times in the same time period . "

This is surprising because the smaller the insect is, the more likely it is that its aerodynamics decrease and to compensate, they tend to flap their wings faster.

"This is just to keep the bees floating in the air without falling to the ground, because they have to transfer honey and pollen in large quantities, sometimes even with body weight, to the herd , " Altshuler said. .

To understand how honey bees carry heavy objects, researchers force them to fly in a small room filled with a mixture of oxygen and helium gas with a smaller density than regular air. This situation makes it more difficult for bees to keep themselves in the air and to allow scientists the opportunity to observe their compensation mechanism into this supplement.

As a result, the bees performed the extra work by stretching the wingspan without adjusting the beating frequency.

Scientists say the finding could lead to the design of a model for aircraft that can hover in the air and carry heavy loads for purposes such as disaster monitoring after earthquakes and tsunamis.
