It's all a matter of perception. The most striking example? How many people have ever been scared by turbulence? 芦And yet, in the entire history of civil aviation, there are no casesknown of airliners crashing for this reason", explains Marco Anghileri, professor of aeronautical engineering at the Polytechnic of Milan. 芦Also because turbulence, like the impact with birds or lightning, is an expected condition and, as such, is part of the design process of an aircraft, which is precisely sized to resist this type of load禄 . THE AIR VACUUM. Turbulence, whether light, moderate or severe, is generated by the mixing of the air due to the collision of hot and cold masses (see image below); It is sometimes called "air vacuum", due to the sensation of falling when pushed downwards, but this is incorrect. The air is in fact always present to support the plane, generating the so-called "lift" on the wings, i.e. the force from bottom to top that counteracts... |
