Hanna Reitsch
Hanna Reitsch (29 March 1912 – 24 August 1979) was a German aviator and test pilot. Along with Melitta von Stauffenberg, she flight tested many of Germany's new aircraft during World War II and received many honors. Reitsch was among the very last people to meet Adolf Hitler alive in the in late April 1945. Reitsch set more than 40 flight altitude records and women's endurance records in gliding and unpowered flight, before and after World War II. In the 1960s, she was sponsored by the West German foreign office as a technical adviser in Ghana and elsewhere, and founded a gliding school in Ghana, where she worked for Kwame Nkrumah. Early life and education Reitsch was born in Hirschberg, Silesia, on 29 March 1912 to an upper-middle-class family. She was daughter of Dr. Wilhelm (Willy) Reitsch, who was an ophthalmology clinic manager, and his wife Emy Helff-Hibler von Alpenheim, who was a member of the Austrian nobility.

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] |
Submarine
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 Autonomous underwater vehicle, 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 navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Focke-Achgelis Fa 330
The Focke-Achgelis Fa 330 ''Bachstelze'' ( en, Wagtail) was a type of rotary-wing kite, known as a rotor kite. They were towed behind German U-boats during World War II to allow a lookout to see further. Development Because of their low profile in the water, submarines could not see more than a few miles over the ocean. To solve this, the German admiralty considered a number of different options, including a folding seaplane (Arado Ar 231). In the end, they chose the Fa 330, a simple, single-seat autogyro kite with a three-bladed rotor. The Fa 330 could be deployed to the deck of the submarine by two people and was tethered to the U-boat by a 150 m (500 ft) cable. The airflow on the rotors as the boat motored along on the surface would spin them up. The kite would then be deployed behind the U-boat with its observer-pilot aboard, raising him approximately 120 meters above the surface and allowing him to see much farther — about 25 nautical miles (46 km) ...

Military Glider
Military gliders (an offshoot of common gliders) have been used by the militaries of various countries for carrying troops (glider infantry) and heavy equipment to a combat zone, mainly during the Second World War. These engineless aircraft were towed into the air and most of the way to their target by military transport planes, e.g., C-47 Skytrain or Dakota, or bombers relegated to secondary activities, e.g., Short Stirling. Most military gliders do not soar, although there were attempts to build military sailplanes as well, such as the DFS 228. Once released from the tow craft near the front, they were to land on any convenient open terrain close to the target, hopefully with as little damage to the cargo and crew as possible as most landing zones (LZ) were far from ideal. The one-way nature of the missions meant that they were treated as semi-expendable leading to construction from common and inexpensive materials such as wood. Most nations seriously attempted to recover as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DFS 230
The DFS 230 was a German transport glider operated by the Luftwaffe in World War II. It was developed in 1933 by the Deutsche Forschungsanstalt für Segelflug (DFS - "German Research Institute for Sailplane Flight") with Hans Jacobs as the head designer. The glider was the German inspiration for the British Hotspur glider and was intended for airborne assault operations. In addition to the pilot, the DFS-230 glider had room for nine men who sat close together on a narrow bench located in the middle of the fuselage (six facing forward, and four backward). Entry and exit to the cramped interior was by a single side door. The front passenger could operate its only armament, a machine gun. It was an assault glider, designed to land directly on top of its target, so it was equipped with a parachute brake. This allowed the glider to approach its target in a dive at an angle of eighty degrees and land within of its target. It could carry up to of cargo. It played significant roles ...

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focke-Achgelis Fa 225
The Focke-Achgelis Fa 225 was an experimental single-seat rotary wing glider built in Nazi Germany by Focke-Achgelis in 1942. Only a single example was constructed. Design and development In the first half of the Second World War, the DFS 230B assault glider was used primarily to land troops and supplies, but was found of limited capability as it needed a relatively large landing area. The Fa 225 was conceived to marry the rotor of the Focke-Achgelis Fa 223 with the fuselage of the DFS 230B, allowing the glider to land in 18 m or less. The rotor was mounted on a framework of struts above the centre of gravity and strengthened long stroke undercarriage units were fitted either side and at the tail.Green 2010, p.337 Towed behind a Junkers Ju 52/3m, Carl Bode piloted the Fa 225 on its first flight in 1943.Kay and Smith 2002, p.291 Construction of the aircraft only took seven weeks, but series production was not proceeded with due to the relatively slow aero-towing speed and change ...

Delmenhorst
Delmenhorst (; Northern Low Saxon: ''Demost'') is an urban district (''Kreisfreie Stadt'') in Lower Saxony, Germany. It has a population of 74,500 and is located west of downtown Bremen with which it forms a contiguous urban area, whereas the city of Oldenburg is to the northwest. The city has a total area of ; and a population density of approx. 1200 inhabitants per km². Since 2021 the mayor has been Petra Gerlach (CDU). History Delmenhorst was first mentioned in a charter in 1254, after the Count of Oldenburg, Otto I, bought the place near the river Delme in 1234. A castle to protect the newly founded settlement was established in about 1247. The following count, Otto II, made the castle his residency; Delmenhorst was declared an independent town on 15 July 1371 under Bremen's law. After a short period under the governance of the bishop of Bremen from 1421 to 1436 Delmenhorst returned under the custody of Oldenburg. Delmenhorst later was infamous for its robber-baronshi ...

Gerd Achgelis
Gerd Achgelis (16 July 1908 – 18 May 1991) was a German aviator, test pilot, and pioneer in the development of helicopters. Biography Achgelis was born in Golzwarden in Oldenburg, and after an apprenticeship as an electrician, began working as a stunt pilot in 1928. In 1930 he flew inverted for an hour over London, and in 1931 he was the German aerobatic champion. Flying a Fw 44 ''Stieglitz'', Achgelis was placed third in the 1934 World Aerobatic Championships in Paris, and was 5th at the 1936 event in Berlin. From April 1932, he also worked as a flying instructor at the Technikum Weimar, and in 1933 became chief test pilot for the Focke-Wulf company in Bremen. On 26 June 1936 he flew the Focke-Wulf Fw 61, considered the first practical helicopter, on its maiden flight. On 27 April 1937, together with Henrich Focke, he founded the company Focke-Achgelis to develop and manufacture helicopters at Hoykenkamp. In 1933 Hermann Göring proposed that Achgelis take a post as an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
