Halberstadt B.II
The Halberstadt B-types of the Halberstädter Flugzeugwerke were two-seat unarmed reconnaissance/training aircraft of the German Air Force in the First World War. Development In 1914, Halberstadt developed a biplane with the Oberursel U.0 rotary engine with 80 hp, which was referred to as Halberstadt B.I and was given the factory name A15. The Halberstadt B.II (B15) was built with a Mercedes D.I inline engine with 105 hp and in 1915 the Halberstadt B.III was produced with the slightly stronger Mercedes D.II (120 hp). Halberstadt B.II was used as the base for the first armed two-seater, the Halberstadt CL.II.

Halberstädter Flugzeugwerke
Halberstädter Flugzeugwerke or Halberstadt was a German aircraft manufacturer. It was formed on 9 April 1912 under the name ''Deutsche Bristol Werke Flugzeug-Gesellschaft mbH'' in Halberstadt, Province of Saxony. History The British-German joint venture initially produced planes according to the system by the Bristol Aeroplane Company, British and Colonial Aeroplane Company, Ltd such as Bristol Boxkites and Bristol Prier monoplanes, but soon expanded into their own developments. In September 1913 the company was renamed ''Halberstädter Flugzeugwerke GmbH''. The chief designers were Hans Burkhardt, who later transferred to Gothaer Waggonfabrik, and the technical director and chief engineer was Karl Theiss. The company built more than 1,700 reconnaissance aircraft (C type) and 85 Fighter aircraft, fighter planes (D type), which served in the ''Luftstreitkräfte'' (German Air Force) during World War I. When German aircraft production was prohibited according to the 1919 Treaty o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Air Force
The German Air Force (german: Luftwaffe, lit=air weapon or air arm, ) is the aerial warfare branch of the , the armed forces of Germany. The German Air Force (as part of the ''Bundeswehr'') was founded in 1956 during the era of the Cold War as the aerial warfare branch of the armed forces of then West Germany. After the reunification of West and East Germany in 1990, it integrated parts of the air force of the former German Democratic Republic, which itself had been founded in 1956 as part of the National People's Army. There is no organizational continuity between the current German Air Force and the former Luftwaffe of the Wehrmacht founded in 1935, which was completely disbanded in 1945/46 after World War II. The term that is used for both the historic and the current German air force is the German-language generic designation of any air force. The commander of the German Air Force is Lieutenant General Ingo Gerhartz. As of 2015, the German Air Force uses eleven air bas ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rotary Engine
The rotary engine is an early type of internal combustion engine, usually designed with an odd number of cylinders per row in a radial configuration. The engine's crankshaft remained stationary in operation, while the entire crankcase and its attached cylinders rotated around it as a unit. Its main application was in aviation, although it also saw use in a few early motorcycles and automobiles. This type of engine was widely used as an alternative to conventional inline engines (straight or V) during World War I and the years immediately preceding that conflict. It has been described as "a very efficient solution to the problems of power output, weight, and reliability". By the early 1920s, the inherent limitations of this type of engine had rendered it obsolete. Description Distinction between "rotary" and "radial" engines A rotary engine is essentially a standard Otto cycle engine, with cylinders arranged radially around a central crankshaft just like a conventional ra ...

Inline Engine (aeronautics)
In aviation, an inline engine is a reciprocating engine with banks of cylinders, one behind another, rather than rows of cylinders, with each bank having any number of cylinders, although more than six is uncommon. The major reciprocating-engine alternative configuration is the radial engine, where the cylinders are placed in a circular or "star" arrangement. The term "inline" is used somewhat differently for aircraft engines than automotive engines. For automotive engines, the term ‘inline’ refers only to straight engines (those with a single bank of cylinders). But for aircraft, ‘inline’ can also refer to engines which are not of the straight configuration, such as V, H, or horizontally opposed. Inline engine configurations ;Straight: Engines with a single bank of cylinders which can be arranged at any angle but typically upright or inverted, (e.g. upright ADC Cirrus, inverted de Havilland Gipsy Major). ; V:Engines with two banks of cylinders with less than 180° betwe ...

Halberstadt CL
Halberstadt ( Eastphalian: ''Halverstidde'') is a town in the German state of Saxony-Anhalt, the capital of Harz district. Located north of the Harz mountain range, it is known for its old town center that was greatly destroyed by Allied bombings in late stages of World War II after local Nazi leaders refused to surrender. The town was rebuilt in the following decades. In World War I, Halberstadt was the site of a German military airbase and aircraft manufacturing facilities. In World War II, Halberstadt was a regional production center for Junkers aircraft, which also housed an SS forced labor camp. Halberstadt now encompasses the area where the Langenstein-Zwieberge concentration camp existed. Geography Halberstadt is situated between the Harz in the south and the Huy hills in the north on the Holtemme and Goldbach rivers, both left tributaries of the Bode.

Trainer (aircraft)
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reconnaissance Aircraft
A reconnaissance aircraft (colloquially, a spy plane) is a military aircraft designed or adapted to perform aerial reconnaissance with roles including collection of imagery intelligence (including using photography), signals intelligence, as well as measurement and signature intelligence. Modern technology has also enabled some aircraft and UAVs to carry out real-time surveillance in addition to general intelligence gathering. Before the development of devices such as radar, military forces relied on reconnaissance aircraft for visual observation and scouting of enemy movement. An example is the PBY Catalina maritime patrol flying boat used by the Allies in World War II: a flight of U.S. Navy Catalinas spotted part of the Japanese fleet approaching Midway Island, beginning the Battle of Midway. History Prior to the 20th century machines for powered and controllable flight were not available to military forces, but some attempts were made to use lighter than air craft ...

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
