The widespread use of composite materials in the creation of new generation aircraft is one of the main trends in the aviation industry. Composites can be used to manufacture the fuselage, wings, tail and other elements of the aircraft, which reduces its weight and increases strength. However, nothing is perfect: over time, the mechanical and strength properties of composite materials deteriorate, which is associated with the accumulation of damage during operation. It is extremely important to calculate exactly how this process takes place in order to increase the resource of aviation products.
Last summer, Hurricane Laura hit the States, which meteorologists called the most destructive in the last few years. Not so long ago, the elements struck a few more blows: in November 2020, Cyclone Eta seriously played out over the Caribbean Sea, and a month before it, the state of Louisiana experienced two storm warnings at once caused by hurricanes Zeta and Delta. All this is not a random set of facts, but an obvious pattern: for some reason, scientists assign female names to destructive hurricanes. We understand why this is happening.
There are a lot of beauties and wonders in Russia that are popular with tourists in the summer, but there are plenty of them in winter. Man–made ice sculptures of Lake Baikal, Shamanic New Year, aurora borealis and others - all the details are in the joint project of Popular Mechanics and S7 Airlines, which has been increasing the number of flights for memorable winter trips since the beginning of December.
Ten scientists and inventors who died during the experiments — not counting Marie Curie.
You may not know everyone listed in this collection, but without the achievements of each of them, today's aviation would be a damn dull sight. The problem is that they are undeservedly forgotten, unlike the well-known two American brothers. Popular mechanics decided to restore justice and recall the six little-known pioneers of aviation.
A lot is known about the northern lights and a lot of those who have observed it personally and taken photos. But only one person has such pictures of a natural phenomenon so far.
Human history is full of inventions that have radically changed our world. Many of them were very large both in size and in historical significance. Popular mechanics has selected eight of the best of the best that helped make the world the way we know it today. Everything is here — from the advent of the Internet and that very quantum accelerator to the banal refrigerator.
These guys are well known to everyone. The creation of the world's first truly flying aircraft, the very first human flight on a heavier—than-air machine with an engine is all their irrepressible handiwork. Did you know that after that flight, the Wright brothers' Flyer-1 no longer took to the skies, they had a bicycle business, they succeeded in printing, while neither Orville nor Wilbur Wright received a high school diploma? And yes, the first fatal plane crash is also them.
One of the many miscalculations that caused the failure of the fascist campaign against the Soviet Union was the underestimation of Soviet science," said academician Sergei Vavilov, who became president of the USSR Academy of Sciences in 1945.
2020 is frighteningly reminiscent of biblical executions: against the backdrop of a deadly pandemic, dozens of countries around the world were struck by a catastrophic invasion of locusts.
