Hans Amtmann
Hans H. Amtmann (1906–2007) was a German aircraft designer. He is best known for his work at Blohm & Voss, where he worked as Head of New Projects under Chief Designer Richard Vogt during the World War II era. After the war, he moved the United States as part of Operation Paperclip, where he worked on a variety of projects. Early years Hans Amtmann was born in Sande, on the outskirts of Bergedorf, near Hamburg in Schleswig-Holstein, Germany, in October 1906. He was the second of two brothers. From the age of nine he was educated at the Hansa School. During this time he learned to play the violin, before moving on to study naval architecture at the State Technical College in Hamburg. In his final term he took a course in aeronautics.Amtmann (1988) German aeroplane designer After only one month working as a naval architect, Amtmann was offered a position as an aircraft designer at Junkers in Dessau. He worked on the wings of the G 38 and Ju 52 all-metal transports, and on in- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Warnemünde
(, literally ''Mouth of the Warnow'') is a seaside resort and a district of the city of Rostock in Mecklenburg, Germany. It is located on the Baltic Sea and, as the name implies, at the estuary of the river Warnow. is one of the world's busiest cruise ports. History Founded in about 1200, was for centuries a small fishing village with minor importance for the economic and cultural development of the region. In 1323 lost its autonomous status as it was purchased by the city of Rostock in order to safeguard the city's access to the Baltic Sea. It was not until the 19th century that began to develop into an important seaside resort. Today has approximately 8,400 inhabitants. Economy Once completely dependent on the fishing industry, 's economic alignment has shifted inevitably from the primary to the secondary and tertiary sector. Besides the Nordic Yards Warnemünde ship yard (the former ), the economy largely depends on tourism. The construction of a modern cruise l ...

Niagara Falls
Niagara Falls () is a group of three waterfalls at the southern end of Niagara Gorge, spanning the border between the province of Ontario in Canada and the state of New York in the United States. The largest of the three is Horseshoe Falls, which straddles the international border of the two countries. It is also known as the Canadian Falls. The smaller American Falls and Bridal Veil Falls lie within the United States. Bridal Veil Falls is separated from Horseshoe Falls by Goat Island and from American Falls by Luna Island, with both islands situated in New York. Formed by the Niagara River, which drains Lake Erie into Lake Ontario, the combined falls have the highest flow rate of any waterfall in North America that has a vertical drop of more than . During peak daytime tourist hours, more than of water goes over the crest of the falls every minute. Horseshoe Falls is the most powerful waterfall in North America, as measured by flow rate. Niagara Falls is famed for its b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed F-80 Shooting Star
The Lockheed P-80 Shooting Star was the first jet fighter used operationally by the United States Army Air Forces (USAAF) during World War II. Designed and built by Lockheed in 1943 and delivered just 143 days from the start of design, production models were flying, and two pre-production models did see very limited service in Italy just before the end of World War II. Designed with straight wings, the type saw extensive combat in Korea with the United States Air Force (USAF) as the F-80. America's first successful turbojet-powered combat aircraft, it was soon outclassed with the appearance of the swept-wing transonic MiG-15 and was quickly replaced in the air superiority role by the transonic F-86 Sabre. The F-94 Starfire, an all-weather interceptor using the same airframe, also saw Korean War service. The closely related T-33 Shooting Star trainer remained in service with the U.S. Air Force and Navy well into the 1980s, with the last NT-33 variant not retired until April ...

Boeing B-17 Flying Fortress
The Boeing B-17 Flying Fortress is a four-engined heavy bomber developed in the 1930s for the United States Army Air Corps (USAAC). Relatively fast and high-flying for a bomber of its era, the B-17 was used primarily in the European Theater of Operations and dropped more bombs than any other aircraft during World War II. It is the third-most produced bomber of all time, behind the four-engined Consolidated B-24 Liberator and the multirole, twin-engined Junkers Ju 88. It was also employed as a transport, antisubmarine aircraft, drone controller, and search-and-rescue aircraft. In a USAAC competition, Boeing's prototype Model 299/XB-17 outperformed two other entries but crashed, losing the initial 200-bomber contract to the Douglas B-18 Bolo. Still, the Air Corps ordered 13 more B-17s for further evaluation, then introduced it into service in 1938. The B-17 evolved through numerous design advances but from its inception, the USAAC (later, the USAAF) promoted the aircraft a ...

Wright Field
Wilbur Wright Field was a military installation and an airfield used as a World War I pilot, mechanic, and armorer training facility and, under different designations, conducted United States Army Air Corps and Air Forces flight testing. Located near Riverside, Ohio, the site is officially "Area B" of Wright-Patterson Air Force Base and includes the National Museum of the United States Air Force built on the airfield. History World War I Wilbur Wright Field was established in 1917 for World War I on of land adjacent to the Mad River which included the 1910 Wright Brothers' Huffman Prairie Flying Field and that was leased to the Army by the Miami Conservancy District. Logistics support to Wilbur Wright Field was by the adjacent Fairfield Aviation General Supply Depot established in January 1918 and which also supplied three other Midwest Signal Corps aviation schools. A Signal Corps Aviation School began in June 1917 for providing combat pilots to the Western Front in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blohm & Voss BV 40
The Blohm & Voss BV 40 was a German glider fighter designed to attack Allied bomber formations during the time of the bombing raids over Nazi Germany. Design The BV 40 was the smallest glider that could accommodate an armoured cockpit and two cannon with limited ammunition. By eliminating the engine and lying the pilot in a prone position (i.e. on his front), the cross-sectional area of the fuselage was much reduced, making the BV 40 harder for bomber gunners to hit. The plane was designed to use non-strategic materials and to be built in as short a time as possible by non-skilled workers. The fuselage was constructed almost entirely of wood. It was of conventional layout, the glider had a high-mounted, straight untapered wing with a similarly-shaped tailplane mounted on the fin just above the fuselage. The pilot lay prone in an armoured steel cockpit in the nose of the aircraft. The front steel plate was thick, and was fitted with a windscreen of thick, armoured glass that g ...

Deutsche Luft Hansa
''Deutsche Luft Hansa A.G.'' (from 1933 styled as ''Deutsche Lufthansa'' and also known as ''Luft Hansa'', ''Lufthansa'', or DLH) was a German airline, serving as flag carrier of the country during the later years of the Weimar Republic and throughout Nazi Germany, when it had close links to the Nazi Party. Although Deutsche Luft Hansa was the forerunner of modern German airline Lufthansa (founded in 1953) and both airlines share the same logo, there is no legal connection between the two. However, the new Lufthansa took over staff from the old airline and considers itself to be in the tradition of it. For this reason it is controversial in the historical reappraisal to what extent the modern Lufthansa should confess to crimes committed by the old airline. History 1920s Deutsche Luft Hansa was founded on 6 January 1926 in Berlin. The name of the company means "German Hansa of the Air". The Hansa or Hanseatic League dominated maritime trade in the Baltic Sea area for hundreds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blohm & Voss P 200
The Blohm & Voss P 200 was a design project for a transatlantic transport flying boat during World War II. It was intended to go into production for Deutsche Lufthansa after the war. History During the early stages of World War II, when it was going well for Germany, the airline Deutsche Lufthansa raised a requirement for a postwar transatlantic flying boat with a capacity of 100 passengers. Blohm & Voss gave the design work to their Head of Preliminary Design, Hans Amtmann, who had the necessary experience.Amtmann, Hans; ''The Vanishing paperclips'', Monogram (1988), pp.67, 72-73.Amtmann, Hans; "Blohm & Voss Remembered", Part I, ''Aeroplane Monthly'', February 1998, pp.26-27. Design Structurally, the P 200 was a scaled-up BV 222 ''Wiking''. It was bigger even than the BV 238, and only the Hughes H-4 Hercules has ever been bigger.Cowin (1963). Its hull accommodated three deck levels, providing luxury facilities for 120 passengers, with additional freight holds fore and aft. ...

Blohm & Voss BV 237
The Blohm & Voss BV 237 was a German proposed dive bomber with an unusual asymmetric design based on the Blohm & Voss BV 141. Design and development In 1942, the ''Luftwaffe'' was interested in replacing the venerable but ageing Junkers Ju 87, and Dr. Richard Vogt's design team at Blohm & Voss began work on project P 177. The dive bomber version would have had a one-man crew with two fixed forward firing MG 151 cannon and two rear firing MG 131 machine guns, carrying of bombs. A two-seat ground attack version was also proposed with two fixed forward firing MG 151 cannon, three forward firing MK 103 cannon with six bombs. A final B-1 type was to incorporate a Junkers Jumo 004B turbojet engine in a third nacelle slung underneath the wing, between the piston engine and the cockpit. In early 1943 the B&V design, now called the BV 237, was shown to Hitler and he ordered it into production. However the order was not carried out.Hans Amtmann; "Blohm und Voss Remembered", Part 2 ...

War Merit Cross
The War Merit Cross (german: Kriegsverdienstkreuz) was a state decoration of Nazi Germany during World War II. By the end of the conflict it was issued in four degrees and had an equivalent civil award. A " de-Nazified" version of the War Merit Cross was reissued in 1957 by the ''Bundeswehr'' for its veterans. History This award was created by Adolf Hitler in October 1939 as a successor to the non-combatant Iron Cross which was used in earlier wars (similar medal but with a different ribbon). The award was graded in the same manner as the Iron Cross: ''War Merit Cross Second Class'', ''War Merit Cross First Class'', and ''Knights Cross of the War Merit Cross''. The award had two variants: ''with swords'' given to soldiers for exceptional service "not in direct connection with combat", and ''without swords'' given to civilians for meritorious service in "furtherance of the war effort". Recipients had to have the lower grade of the award before getting the next level. The weari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blohm & Voss
Blohm+Voss (B+V), also written historically as Blohm & Voss, Blohm und Voß etc., is a German shipbuilding and engineering company. Founded in Hamburg in 1877 to specialise in steel-hulled ships, its most famous product was the World War II battleship '' Bismarck''. In the 1930s, its owners established the Hamburger Flugzeugbau aircraft manufacturer which, shortly before the outbreak of World War II, adopted the name of its parent company. Following a difficult period after the war, B+V was revived, changing ownership among several owners, as Thyssen Group and Star Capital. In 2016, it became a subsidiary of Lürssen and continues to supply both the military and civilian markets. It serves two areas – new construction of warships as NVL B.V. & Co. KG, and new construction and refitting of megayachts.Meyer, Kristian"Erste Bilanz nach Übernahme Alles neu bei Traditionswerft Blohm+Voss" ''Hamburger Morgenpost'', 27 April 2018.
