Why can heavy aircraft fly like birds?

In fact, the flight of the aircraft and the birds have many similarities.

The largest commercial aircraft in the world can weigh up to under 500 tons, while the largest bird that can fly currently has a body weight of only about 16kg. However, you may be surprised to know the fact that the aircraft and the birds are based on a common principle to be able to fly.

To fly, both aircraft and birds have to win the Earth attraction.

Accordingly, one of the basic principles of flying is to resist the Earth's attraction to the largest 'ally' is air. Planes and birds fly by taking advantage of air atoms around them. When beating the wings, the birds will create a high air pressure area under the wing, while the upper area is a low air pressure area. This principle also appears when the plane moves on the runway. The difference in air pressure in the area under the wing of the aircraft and on the wing of the airplane gives it a lift. When this force wins the Earth's gravity, the plane will fly up.

To take off, the plane must first reach high speed on the runway.

Of course, a 500-ton aircraft will need more force than a bird and a plane does this in two ways. First, the aircraft will have to travel on the ice with a speed of about 242km / h to 289km / h to create fast air zones around the wing area. Besides, aircraft can also fly up thanks to something called 'attack angle'. You may have noticed, instead of lifting the plane up into the air after moving on the runway at high speed, the plane took off by bringing the plane head up and the tail to the rear, forming an 'attack angle'. The creation of this "attack angle" helps to gain even more air under the wing, meaning more pressure.

Once in the air, what makes the aircraft able to maintain its engine position with one of the functions is to create an air stream that runs along the wing. As the aircraft flies higher, it is not difficult to dilute, so the aircraft will have to move at a higher speed to maintain its mid-frame status.

Accordingly, the flight speed of the aircraft can be up to 880km / h. However, thin air means less drag, so the aircraft can fly higher and consume less energy.

The next time you have the opportunity to fly, perhaps you will feel more interesting with your experience!
