Soviet K-class Submarine
The K class were the largest submarines built for the Soviet Navy in the World War II era. Design The design was approved in 1936 as a long range "cruiser submarine" with a heavy torpedo and gun armament. The boats could operate as a "fleet submarine" working with the battle fleet or as long range commerce raiders. They were a significantly improved version of the and overcame most of their shortcomings (Conway's Fighting Ships). The double hull was divided into seven compartments. It was originally planned to carry a small floatplane for scouting but this concept was abandoned when the planned aircraft proved too flimsy. Yakubov and Worth state that these were the most successful Soviet submarines of the World War II era, with high speed and good seakeeping. This class of submarine possessed better ventilation and air conditioning systems than any other class of Soviet submarine in World War II. They had amenities such as a bunk for every sailor, small cabins for each off ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shadowgraph Kreiserskaya Class Submarine
Shadowgraph is an optical method that reveals non-uniformities in transparency and translucency, transparent media like air, water, or glass. It is related to, but simpler than, the schlieren and schlieren photography methods that perform a similar function. Shadowgraph is a type of flow visualisation. In principle, a difference in temperature, a different gas, or a shock wave in the transparent air cannot be seen by the human eye or cameras. However, all these disturbances refract light rays, so they can cast shadows. The plume of hot air rising from a fire, for example, can be seen by way of its shadow cast upon a nearby surface by the uniform sunlight. Sunlight shadowgraph Some aquatic predators detect their transparent prey by way of their shadows cast upon the ocean floor. It was Robert Hooke who first scientifically demonstrated the sunlight shadowgraph and Jean-Paul Marat who first used it to study fire. A modern account of shadowgraphy is given by Gary S. Settles. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Submarine Classes
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of ...
