U-505
''U-505'' is a German Type IXC submarine built for Germany's ''Kriegsmarine'' during World War II. She was captured by the U.S. Navy on 4 June 1944. In her uniquely unlucky career with the ''Kriegsmarine'', she had the distinction of being the "most heavily damaged U-boat to successfully return to port" in World War II on her fourth patrol, and the only submarine in which a commanding officer took his own life in combat conditions on her tenth patrol, following six botched patrols. She was captured on 4 June 1944 by United States Navy Task Group 22.3 (TG 22.3), one of six U-boats that were captured by Allied forces during World War II. All but one of ''U-505''s crew were rescued by the Navy task group. The submarine was towed to Bermuda in secret and her crew were interned at a US prisoner of war camp, where they were denied access to International Red Cross visits. The Navy classified the capture as top secret and prevented the Germans from discovering it. In 1954, ''U-505'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peter Zschech
Peter Zschech (1 October 1918 – 24 October 1943) was the second commander of the . He earned notoriety as the first commanding officer to commit suicide while in active command of a naval vessel, as well as the only submariner to ever do so while underwater. History with ''U-505'' ''U-505''s first and very successful commander was ''Kapitänleutnant'' Axel Löwe, who was relieved for illness in October 1942. Löwe was replaced by Zschech, a veteran U-boat officer, who served for a year as watch officer in . Zschech was described as a "hard" commander, ambitious in his first command, indifferent to the morale of his men, and bad-tempered. On 11 November 1942, a month into her first war patrol under Zschech, ''U-505'' was heavily damaged by air attack in the Caribbean Sea. The direct impact of a 250-lb bomb from a Lockheed Hudson on the foredeck tore the deck gun from the boat and severely breached the hull. Zschech ordered his men to abandon ship but his officers refused and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Museum Of Science And Industry (Chicago)
The Museum of Science and Industry (MSI) is a science museum located in Chicago, Illinois, in Jackson Park, in the Hyde Park neighborhood between Lake Michigan and The University of Chicago. It is housed in the former ''Palace of Fine Arts'' from the 1893 World's Columbian Exposition. Initially endowed by Julius Rosenwald, the Sears, Roebuck and Company president and philanthropist, it was supported by the Commercial Club of Chicago and opened in 1933 during the Century of Progress Exposition. Among the museum's exhibits are a full-size replica coal mine, captured during World War II, a model railroad, the command module of Apollo 8, and the first diesel-powered streamlined stainless-steel passenger train (''Pioneer Zephyr''). History The Palace of Fine Arts (also known as the Fine Arts Building) at the 1893 World's Columbian Exposition was designed by Charles B. Atwood for D. H. Burnham & Co.

German Type IX Submarine
The Type IX U-boat was designed by Nazi Germany's ''Kriegsmarine'' in 1935 and 1936 as a large ocean-going submarine for sustained operations far from the home support facilities. Type IX boats were briefly used for patrols off the eastern United States in an attempt to disrupt the stream of troops and supplies bound for Europe. It was derived from the Type IA, and appeared in various sub-types. Type IXs had six torpedo tubes; four at the bow and two at the stern. They carried six reloads internally and had five external torpedo containers (three at the stern and two at the bow) which stored ten additional torpedoes. The total of 22 torpedoes allowed U-boat commanders to follow a convoy and strike night after night. Some of the IXC boats were fitted for mine operations; as mine-layers they could carry 44 TMA or 66 TMB mines. Secondary armament was provided by one deck gun with 180 rounds. Anti-aircraft armament differed throughout the war. They had two periscopes in the towe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2nd U-boat Flotilla
The 2nd U-boat Flotilla (German ''2. Unterseebootsflottille''), also known as the Saltzwedel Flotilla, was the second operational U-boat unit in Nazi Germany's ''Kriegsmarine''. Founded on 1 September 1936 under the command of ''Fregattenkapitän'' Werner Scheer, it was named in honour of ''Oberleutnant zur See'' Reinhold Saltzwedel. Saltzwedel, a U-boat commander during World War I, died on 2 December 1917, when his submarine ''UB-81'' was sunk by a mine in the English Channel. The flotilla was based in Kiel for the first few weeks after its formation, but was later moved to Wilhelmshaven, where it remained until May 1940. In June 1940, the flotilla was moved to Lorient in France France (), officially the French Republic ( ), is a country primarily located in Western Europe. It also comprises of Overseas France, overseas regions and territories in the Americas and the Atlantic Ocean, Atlantic, Pacific Ocean, Pac ... until it was disbanded in August 1944. Flotilla Co ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercharged
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. Des ...

Siemens-Schuckert
Siemens-Schuckert (or Siemens-Schuckertwerke) was a German electrical engineering company headquartered in Berlin, Erlangen and Nuremberg that was incorporated into the Siemens AG in 1966. Siemens Schuckert was founded in 1903 when Siemens & Halske acquired Schuckertwerke. Subsequently, Siemens & Halske specialized in communications engineering and Siemens-Schuckert in power engineering and pneumatic instrumentation. During World War I Siemens-Schuckert also produced aircraft. It took over manufacturing of the renowned Protos vehicles in 1908. In World War II, the company had a factory producing aircraft and other parts at Monowitz near Auschwitz. There was a workers camp near the factory known as Bobrek concentration camp. The Siemens Schuckert logo consisted of an S with a smaller S superimposed on the middle with the smaller S rotated left by 45 degrees.Siemens used this as a theme for their logos with absorbed companies: Siemens & Halske's logo was a large S with a small sup ...

MAN SE
MAN SE (abbreviation of ''Maschinenfabrik Augsburg-Nürnberg'', ) was a manufacturing and engineering company based in Munich, Germany. Its primary output was commercial vehicles and diesel engines through its MAN Truck & Bus and MAN Latin America divisions, and participation in the manufacturer Sinotruk. MAN SE was majority-owned by Traton, the heavy commercial vehicle subsidiary of automaker Volkswagen AG, until August 2021 when Traton completed a squeeze out of all remaining shareholders and formally merged MAN SE into Traton SE, meaning the former subsidiaries of MAN SE were now directly owned by Traton, and MAN SE ceased to exist. History Foundation MAN traces its origins back to 1758, when the "St. Antony" ironworks commenced operation in Oberhausen, as the first heavy-industry enterprise in the Ruhr region. In 1808, the three ironworks "St. Antony", "Gute Hoffnung" (English: "Good Hope"), and "Neue Essen" (English: "New Forges") merged, to form the Hüttengewerks ...

Draught (ship)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
