When did the first icebreaker appear?

For navigation in the northern ice, transport and military vessels with a special hull shape are used - icebreakers. They pave the way for the rest of the ships that carry important cargo through the ice. Their hulls made of the strongest thick steel are egg-shaped and are not afraid of ice.

The history of icebreakers is very old. Back in 1864, the Kronstadt merchant Britnev decided to cut the bow of one of his steamships. It was this innovation that allowed a small ship only 26 meters long to extend navigation between Kronstadt and Oranienbaum for several weeks. In 1933 the Swedes built the first diesel-electric icebreaker Imer. A powerful power plant significantly increased the icebreaker's cruising range in the northern seas.

The largest and most powerful were Soviet icebreakers. One of them was completed in the city of Leningrad in August 1941 and went to the front instead of the northern seas. He fought quite successfully, but soon the guns were removed from him, and he went to fulfill his direct duties - to escort warships and cargo ships through the northern seas with the most necessary for the front.

The beginning of a new era in polar navigation was marked by the historic voyage of the Soviet nuclear-powered icebreaker Arktika. On August 17, 1977, the Arktika, having overcome a strip of heavy ice, reached the geographic North Pole for the first time. Nuclear-powered icebreakers can break through a huge thickness of ice. The special shape of the stern protects the propeller, and in case of breakage, its blades can be replaced without entering the port. There are several helicopters on board the nuclear-powered ship.

Random interesting fact from the Great Encyclopedia:

What is the TNT equivalent?

TNT equivalent is the energy characteristic of an explosion of a nuclear or thermonuclear charge.

Quantitatively, the TNT equivalent is equal to the mass of the conventional charge of the chemical explosive trinitrotoluene (TNT), the explosive decomposition energy of which is equal to the energy released in a given nuclear explosion. The TNT equivalent is measured in kilotons (thousand tons) and megatons (millions of tons).

A nuclear explosion of one kilogram of uranium-235 or plutonium-239 with complete fission of all nuclei is equivalent in terms of the amount of energy released to a chemical explosion of 20 thousand tons of trinitrotoluene.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
