In Japan have developed a system warning about the hit airplane turbulence
The device detects the presence of the turbulence at the distance of 18 km, after which the crew has about 70 seconds to seat the passengers and stop the service in the cabin.
TOKYO, may 28. /Offset. TASS Alex Sarachev/. The Japanese aerospace exploration Agency (JAXA) has developed a system warning about contact with aircraft in turbulence. On that Sunday said the Agency Kyodo.
The principle of operation of a new device based on the use of laser beams. Their beam catches the light dissipated upon contact with the water particles and dust in the air. Thus, the system detects the wavelength of light, which varies depending on the intensity of air flow, and determine the presence of turbulence at the distance of 18 km.
This gives the crew about 70 seconds to during the flight in advance to include a warning sign, to stop the service in the cabin and seated passengers. Particularly useful information about the presence of turbulence during the landing.
Unlike modern aircraft radars, development of JAXA can detect turbulence not only in rain clouds, but good weather conditions. The device itself weighs 150 kg and is attached to the front of the fuselage. To date, Japanese experts have played 19 tests in a small plane at a height of from 0.6 to 12 km.
