Working as an artillery engineer, he witnessed the First War of Schleswig, German/Danish war for Schleswig-Holstein between 1848 and 1851. Seeing how the Prussian coast was easily blockaded by the Danish navy, Bauer quickly developed a plan to build a new type of submersible ship to help break the blockade. He began studying hydraulics and shipbuilding, ship construction. However, before his studies could get very far, the troops of the German Confederation decided to withdraw and surrendered Schleswig-Holstein to Denmark. However, Bauer was determined to realize his plan at any cost and left the Bavaria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Initially called Gunboat No. 1, ''Von der Tann'' was the most modern of these ships.

Brandtaucher
''Brandtaucher'' (German for ''Fire-diver'') was a submersible designed by the Bavarian inventor and engineer Wilhelm Bauer and built by Schweffel & Howaldt in Kiel for Schleswig-Holstein's Flotilla (part of the ''Reichsflotte'') in 1850. The ''Brandtaucher'' is the oldest known surviving submarine in the world. History In January 1850, Bauer, a cavalryman during the German-Danish War, designed ''Brandtaucher'' as a way to end the Danish naval blockade of Germany. Bauer's early sketch attracted the attention of the Minister of Marine, who allowed him to construct a model. The model was demonstrated in Kiel harbour in front of naval dignitaries. Its satisfactory performance led to the construction of a full-scale model, which was funded by contributions from army personnel and local civilians. Due to the inadequate funding, the scale of the boat had to be downgraded and the design altered and simplified; resulting in a reduced diving depth from 30 m to 9.5 m. This redesign ...

U-boat
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
