Su-27 and MiG-29, Will Soviet-made Ukrainian planes carry British long-range missiles?

Su-27 and MiG-29, Will Soviet-made Ukrainian planes carry British long-range missiles?  The Su-27 and MiG-29 fighters are not fit to carry the long-range Storm Shadow missiles delivered by Britain to Ukraine.  These missiles can currently be carried by Eurofighter Typhoon, Rafale, Mirage 2000 and Tornado aircraft.  Therefore, the Kiev regime's army will need some time to adapt these British and French-made missiles to warplanes produced by the Soviet Union in the 1980s.  It is noteworthy that the design of the ultra-precise "air-to-ground" Storm Shadow missiles began in Britain and France 30 years ago. Its serial industrial production was launched in 2001, and the missiles were used in Libya, Iraq, Yemen and Syria.  Storm Shadow is dedicated to directing air strikes on important facilities, including well-protected ones, such as underground bunkers. The missiles fly towards the target at a height of 30-40 meters, relying on satellite navigation and electronic maps of the Earth, in order to avoid being intercepted by air defenses.  Experts consider that Kiev has received export models of Storm Shadow with a working range of 250 km, knowing that its basic models can be launched to a distance of 560-km.  While experts do not rule out that the Ukrainian and British experts had previously equipped Soviet-made aircraft to carry these long-range missiles before information was leaked about their delivery to Ukraine. It is not excluded that they were also launched from gunboats.      Paleontologists and chemists : Plants colonized the land 440 million years ago  Paleontologists and chemists have uncovered geochemical evidence that complex plants colonized the Earth 444 million years ago, early in the Silurian period.  E. about 14 million years earlier than previously thought. This was announced by the press service of the Chinese Academy of Sciences.  A report published by the academy states: “Paleochemists used data on mercury isotopes in Paleozoic sediments to elucidate when Earth was first colonized by complex plants. Their analysis of paleosoil sediments showed that this happened at least 444 million years ago, at the beginning of the Silurian period.”  And no one knows what these first trees and forests looked like, so far only a few "petrified forests" are known, as complete trunks and some root systems remain in the depths of their rocks. And the study of these fossils showed that the early Paleozoic plants looked very strange. And a special light bark at that time played the role of leaves in the first trees, but in general they did not look like modern trees, but rather resembled giant corn cobs and reeds.  An international team of paleontologists and chemists led by Dr. Fen Xinbin, a professor at the Institute of Geochemistry under the Chinese Academy of Sciences, presented the first evidence that the ancestors of the first trees on Earth began colonizing the Earth much earlier than previously thought. The researchers made this discovery while studying the isotopic composition of Silurian rocks.  The Chinese scientists also explained that they were mainly interested in the number of Hg-199 and Hg-200 atoms contained in the said deposits. Plant leaves actively absorbed these isotopes from the atmosphere, so that the sedimentary rocks formed contain much less Hg-199 and Hg-200 than similar minerals that originated in other regions of the Earth without vegetation.  Based on this hypothesis, Professor Feng Xinbin and his colleagues measured the proportions of Hg-199 and Hg-200 in rocks formed in different periods of the Paleozoic era, starting from the Cambrian stage (520 million years ago) and ending with the Permian stage (250 million years ago). The measurements made by the scientists showed unexpectedly that low levels of Hg-199 and Hg-200 were characteristic not only of Middle Devonian sediments but also of rocks formed 444 million years ago, at the beginning of the Silurian period.       Messi or Ronaldo? Which is better able to play in the Saudi Arab climate temperatures? A study provides the answer  Taller, leaner footballers like Erling Haaland and Cristiano Ronaldo may outpace shorter athletes like Lionel Messi in the future because of climate change.  Meanwhile, lean tennis players like Andy Murray may find that they are better at athletic competitions when the temperature is hotter.  And a new study looking at the performance of professional athletes found that taller men run faster when temperatures are higher.  The shorter and shorter men did better when the weather was cooler.  The new study concludes that people are somewhat like animals, which tend to be stockier in cooler regions, like polar bears, and more slender, like brown bears, in hotter places - perhaps because this better suits conditions. .  The analysis was conducted on 173 athletes competing in nearly 200 Ironman Extreme races over two decades.  And it turns out that the taller and thinner men are about 2.5% faster when temperatures are higher, compared to short men, according to the study's author, Professor Ryan Calsbeck of Dartmouth University in the United States.  This is likely because the body has a larger surface area, so it can dissipate heat from more skin and produce more sweat to cool it.  The women also seemed to run faster in the higher temperatures when they had longer legs, but not significantly.  This may be because women produce less sweat than men, so having longer legs to sweat than in hot weather makes less of a difference.  The study only found a difference in ultra-running performance, but Professor Kalsbeck said the findings could apply to other sports.  It could mean that the summer soccer leagues are getting hotter, and footballers like Manchester City star Erling Haaland and the star of Saudi Arabia's Al-Nassr club, Cristiano Ronaldo, may be doing better than Wayne Rooney or Lionel Messi.  Professor Kalsbeck, whose new study was published in the journal PLOS One, said: 'People attempting a personal best can consider sports venues and average temperatures to choose a venue based on whether they are thin and long-limbed or vice versa. These results certainly indicate that a tennis player A skinny man like Andy Murray might do better at a warmer US Open than Wimbledon, or a cyclist like Chris Froome might do well if he wanted to run marathons in warm countries.”  The study included nearly 150-mile triathlons in extremely hot locations such as Hawaii and South Africa, and cooler countries such as Finland and Canada.  Maximum temperatures ranged from less than 18 degrees Celsius (64 degrees Fahrenheit) to nearly 39 degrees Celsius (102 degrees Fahrenheit).  The research compared the athletes' height and digitally measured leg and arm lengths from race photos.  The men were found to be faster at running when temperatures were higher, but not at cycling, which may be affected less by heat due to airflow, or during swimming, which involves wearing a warm suit even when it's cold.  The findings support the 19th-century theories of biologists Carl Bergmann and Joel Asaph Allen that animals' overall body size, as well as the length and thickness of their limbs, are related to their climate.        Russia Russian company "Carbontex" creating looms to produce spare parts for drones   The media office of the National Technology Initiative announced that the experts of the Russian company "Carbontex" have created 3D looms with which it is possible to produce ultra-durable materials.  According to the office, this technology allows carbon threads to be weaved in three directions and the possibility of connecting parts at different angles. This technology can be used in the production of spare parts for light drones.  The technology of manufacturing three-dimensional tissue products with pre-programmed properties is considered promising for aviation, because it allows, at the design stage, to adjust the thickness of materials in the required places or adjust their flexibility and durability.  According to the media office, "The durability of this material allows it to be used in the production of drones with improved aerodynamic characteristics and durability. The 3D printing technology allows for a reduction in the cost of production, including polymer composite materials, thanks to the high level of automation. Also, the use of reinforcing fibers in these materials will help eliminate One of the main drawbacks observed in traditional production.  Vyacheslav Rogozhnikov, General Director of Carbontex, says: “The looms allow weaving in length, width and height and connecting two planes not only vertically, but also at different angles. This arrangement of the fibers creates a very dense, homogeneous and durable volumetric woven material, the use of which allows to increase the production of lightweight and highly durable drones. controllable and increase its load.          Russian engineers invent a drone with miraculous specifications : National Technology Initiative  The media office of the National Technology Initiative announced that Russian engineers have created a vertical take-off and landing drone that can fly 12 hours at an altitude of 8,000 meters.  The office's statement read: "Russian engineers have created an unparalleled "Begalet-Mirage" drone that takes off and lands vertically and can fly for 12 hours at an altitude of up to 8,000 meters."  Alexander Begak, Director of Aeronet - BEGAK Aerospace Development, says: "We have created a practical model of the drone, weighing 75 kg, including 20 kg of potential payload, that can fly at an altitude of 6-8 thousand meters. Such a drone is currently required in the market to carry out various tasks. First and foremost Everything, to restore the communication signal during emergencies such as floods, as well as to monitor forest fires or a gas pipeline and other national economic tasks.  Pejak notes that the flight time of the electric motor-powered drone is about two hours, or about 350 km. But in the hybrid version, which is equipped with an electric motor and an internal combustion engine, it will be able to fly for 12 hours.  He says, “This plane has a non-classical aerodynamic scheme, which allows it to take off from any position not designated for this purpose—I think even from the deck of a ship. Generally, I cannot reveal the features of this plane in detail. But I can say that we have already made many flights, and it will We will start doing other tests soon."
