Sack AS-5
The Sack AS-6 was a German prototype circular-winged aircraft built privately during the Second World War. Design and development In July 1938, local farmer Arthur Sack entered his AS-1 circular-winged model in the first Reich-Wide Contest for Motorized Flying Models, which was held at Leipzig. The model had poor flight characteristics and had to be hand launched. However, Ernst Udet showed interest in Sack's design, and encouraged him to continue his research into circular wing aircraft for possible use as an observation or attack aircraft. Sack went on to built four additional models based on the AS-1, with each increasing in size, before building the full-sized prototype as the AS-6 V1. The AS-6 V1 was built in January 1944 by Mitteldeutsche Motorwerke, with final assembly at the Flugplatz-Werkstatt workshop located at the air base in Brandis, Germany. The aircraft was built with the landing gear, cockpit, and pilot seat from a Messerschmitt Bf 109B, and was powered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand-Year Reich, ended in May 1945 after just 12 years when the Allies defeated Germany, ending World War II in Europe. On 30 January 1933, Hitler was appointed chancellor of Germany, the head of gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jagdgeschwader 400
Jagdgeschwader 400 (JG 400) was a Luftwaffe fighter-wing of World War II. JG 400 was formed on 1 February 1944 in Brandis with '' Stab'' only for the Messerschmitt Me 163 rocket fighter, as the only military aviation unit of any size in history, to actively use rocket-powered combat aircraft in wartime. Major Wolfgang Späte, of JG 54 was transferred into the experimental flying unit ''Erprobungskommando 16'' at Bad Zwischenahn in Northern Germany, where the Messerschmitt Me 163 Komet was under development and tactical testing. Once the Me 163B was declared operational in July 1944, Späte was given command of the formally raised JG 400, ultimately the only front-line unit to use the Me 163 operationally. Due to the meteoric rate of climb and limited endurance of the Komet, the Luftwaffe intended to locate individual ''Staffeln'' of Komets at strategic points in Germany to intercept Allied bomber formations en route to targets. JG 400 was initially based at Venlo, Netherlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vought XF5U
The Vought XF5U "Flying Flapjack" was an experimental U.S. Navy fighter aircraft designed by Charles H. Zimmerman for Vought during World War II. This unorthodox design consisted of a flat, somewhat disc-shaped body (hence its name) serving as the lifting surface. Two piston engines buried in the body drove propellers located on the leading edge at the wingtips. Design and development A developed version of the original V-173 prototype, the XF5U-1 was a larger aircraft. Of all-metal construction, it was almost five times heavier, with two 1,400 hp (1,193 kW) Pratt & Whitney R-2000 radial engines. The configuration was designed to create a low aspect ratio aircraft with low takeoff and landing speeds but high top speed. The aircraft was designed to keep the low stall speed and high angle of attack from the V-173 prototype while providing for better pilot visibility, cockpit comfort, less vibration, and provisions to install armament. This included a cockpit redesign m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vought V-173
The Vought V-173 "Flying Pancake" was an American experimental test aircraft built as part of the Vought XF5U program during World War II. Both the V-173 and the XF5U featured an unorthodox "all-wing" design consisting of flat, somewhat disk-shaped bodies (hence the name) serving as the lifting surface. Two piston engines buried in the body drove propellers located on the leading edge at the wingtips. Design and development In the 1930s, Charles H. Zimmerman was a noted aeronautical engineer who advocated the concept of "discoidal" aircraft, the so-called "Zimmer Skimmer" and worked on a variety of projects on his own and with the Vought company. After testing using scale models, including a remotely controlled, electrically powered large-scale model, designated the Vought V-162, the US Navy approached Zimmerman and offered to fund further development. Data and concept documentation was given to the Navy in 1939, with wind tunnel tests on full-scale models being completed in 19 ...

Nemeth Parasol
Nemeth Parasol was a prototype of a taildragger tractor configuration airplane with circular wing set in a parasol configuration. It was designed by Steven Nemeth from Dayton, Ohio and made its first flight in 1934. The goal was to have a plane that could be stored in a large garage, rather than a hangar and be easy to fly. Nemeth did wind tunnel tests at the University of Michigan in 1929. Nemeth worked with students from the University of Miami in 1934 to help him build the plane's wings. Nemeth used his custom "roundwing" on an Alliance A-1 Argo two-seat biplane fuselage. The high-wing monoplane had multiple struts to hold the custom "roundwing". Nemeth wing had a diameter of fifteen feet (4.57m) with flaps and ailerons. The plane reached a top speed of 135mph (217km/h). Due to the large wing, the plane could taking off in just 63 feet (19 metres). Tests were done with stall speeds, turning off the engine in flight, and using the wings as a parachute. The parachute-stall landing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lee-Richards Annular Monoplane
During the pioneer years before the First World War, Cedric Lee and G. Tilghman Richards in the UK built and flew a series of aircraft having a novel flat ring-shaped or annular wing. They built both biplane and monoplane types, and in 1913 their first monoplane proved to be an early example of a statically stable aircraft. History Annular biplane Following a series of patents on circular-wing aircraft taken out by Williband Franz Zelger and Isaac Henry Storey, the boiler engineer John George Aulsebrook Kitchen built an annular-wing biplane but was unable to fly it. He later took out his own patent, while he and Storey also jointly patent an entirely different type of multiplane.Jarrett (1976) Kitchen subsequently sold both the patent and the machine to Cedric Lee, who would also later acquire Zelger's patent. Tilghman Richards joined Lee in 1910 and together they finished the aeroplane, fitting a Gnome Omega engine in the front. The machine is known variously as the Kitchen ...

V8 Engine
A V8 engine is an eight-cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. The first V8 engine was produced by the French Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient, lower capacity engines, or hybrid and electric drivetrains. Design V-angle The majority of V8 engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations; however, the downside is a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

MK 108 Cannon
The MK 108 (German: ''Maschinenkanone''—"machine cannon") was a 30 mm caliber autocannon manufactured in Nazi Germany, Germany during World War II by Rheinmetall‑August Borsig, Borsig for use in aircraft. The cannon saw widespread use as an anti-bomber weapon during the second half of the war, first seen in 1943 in the Messerschmitt Bf 110, Bf 110G-2 bomber destroyers and Messerschmitt Bf 109, Bf 109G-6/U4. Four MK 108's formed the main armament of the Messerschmitt Me 262, Me 262 the next year. It could be found on some versions or optional mountings on practically every other German fighter aircraft, fighter of the era. Development The weapon was developed as a private venture by the company in 1940 and was submitted to the ''Reich Air Ministry, Reichsluftfahrtministerium'' (RLM—Reich Aviation Ministry) in response to a 1942 requirement for a heavy aircraft weapon for use against the Allies of World War II, Allied heavy bombers appearing over German-controlled regions by ...

Nazi UFOs
In ufology, conspiracy theory, science fiction, and comic book stories, claims or stories have circulated linking UFOs to Nazi Germany. The German UFO theories describe supposedly successful attempts to develop advanced aircraft or spacecraft prior to and during World War II, further asserting the post-war survival of these craft in secret underground bases in Antarctica, South America, or the United States, along with their creators. Early UFOs as possible Nazi technology During the Second World War, unusual sightings in the skies above Europe were often interpreted as novel Nazi technology. In the first years of the Cold War, Western nations speculated that unusual sightings might stem from Soviet deployment of captured or reverse-engineered Nazi technology. Foo fighters In World War II, the so-called "foo fighters", a variety of unusual and anomalous aerial phenomena, were witnessed by both Axis and Allied personnel. While some foo fighter reports were dismissed as the mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strafing
Strafing is the military practice of attacking ground targets from low-flying aircraft using aircraft-mounted automatic weapons. Less commonly, the term is used by extension to describe high-speed firing runs by any land or naval craft such as fast boats, using smaller-caliber weapons and targeting stationary or slowly-moving targets. Etymology The word is an adaptation of German ''strafen'', to punish, specifically from the humorous adaptation of the German anti-British slogan ''Gott strafe England'' (May God punish England), dating back to World War I. Description Guns used in strafing range in caliber from machine guns, to autocannon or rotary cannon. Although ground attack using automatic weapons fire is very often accompanied with bombing or rocket fire, the term "strafing" does not specifically include the last two. The term "strafing" can cover either fixed guns, or aimable (flexible) guns. Fixed guns firing directly ahead tend to be more predominant on fixed ...
