Why the airplane window round? Why do aircraft have curved ends of the wings? Why always the passengers sit in the aircraft on the left side? Everything connected with the aircraft, well planned and thought out. Perhaps this is the main reason why the aircraft - the safest way to travel. We will respond to 8 the most popular questions about the aircraft.

1. Why did the plane window round?

In the early 1950s, he developed Havilland Comet, the world's first commercial jet airliner. It was literally a miracle. But a year later, he collapsed right in the sky. A few months later another 2 aircraft crashed. Engineers conducted a diagnosis of each screw of the plane and found the problem: the windows were square. The fact that the pressure is growing on the corners of square windows, and this pressure is increasing during the flight. It was therefore decided to make a round window. With this solution, the flights are now much safer.

2. Why do aircraft have curved ends of the wings?

During flight the pressure in the upper part of the wing is lower than the bottom of the wing. The air tends to move from high pressure below the wings to the low pressure above the wing around the wing tip. In the past, the tips of the wings were straight, and the air flow causes strong turbulence. Therefore, the researchers decided to bend the wing tips up to reduce turbulence to extend the life of the wings and save a lot of fuel when traveling. With this feature, we feel more comfortable during the flight.

3. Why do airplanes different shaped nose?

military aircraft nose is pointed. The sharper nose, the faster plane. But the longer the nose prevents pilots right to see the runway, so airliners have rounded noses. But Russian engineers have solved this problem in the 60-ies. They invented the fastest passenger plane that could tilt the nose. During takeoff and landing aircraft nose down tilted. During the flight, the nose has been returned to its original position.

4. Why are planes painted white?

Aircraft are almost always painted white. This is for several reasons: The thermal reflection. If the plane is painted white, it accumulates less heat. It is better for passengers and cost effective for airlines. White paint is cheaper. Birds see better reflection from white surfaces and for this reason are not often faced with the aircraft. White paint helps to identify even small cracks and dents.

exit 5. Why the left?

Not all, but most of the aircraft are the main passenger entrance on the left side. There are different theories to explain this fact. The right side of luggage (cargo hatches and right), so that it is not safe for passengers. Some people say that it is a tradition of the past: the ramps ships have always been on the left.

6. Why do some planes have a strange shape? You've probably heard about the plane, which is also called stealth aircraft. It has an odd shape for a simple reason: its shape makes it less visible to radar, sonar, infrared and other detection methods. Moreover, it enables the aircraft to carry more luggage and consume less fuel.

7. planes appear spacious?

Designers use several techniques to aircraft look larger and more spacious than they really are. For example, the walls are shaped to reflect light properly. Lighting between the ceiling and the top drawer makes the ceiling visually higher. With these tricks for people who suffer from claustrophobia, it is easier to travel by plane.

8. Why not have a beard pilots?

Some airlines do not allow pilots to have a beard. The fact is that facial hair may interfere with the fact that the oxygen mask firmly against the face of the pilot and worked properly. In case of emergency, pilots must remain conscious, to be able to save lives.
