Willy Messerschmitt
Wilhelm Emil "Willy" Messerschmitt (; 26 June 1898 – 15 September 1978) was a German aircraft designer and manufacturer who designed a number of prominent aircraft for the ''Luftwaffe'' and civil aviation. Messerschmitt designed a number of successful motor gliders and airliners in the early 1920s until the BFW M.20 damaged his reputation, put his company into bankruptcy, and earned the hate of future Reich Aviation Ministry chief Erhard Milch. Messerschmitt rebuilt his company and produced a number of successful military aircraft for the ''Luftwaffe'' during World War II, until he was blacklisted from government contracts by Milch in 1941 and the Me 210 damaged his reputation again in 1942, forcing him to resign as direct and into a research and development role. Messerschmitt was accused of using forced labor for aircraft production and convicted of collaborating with the Nazi regime in 1948. Messerschmitt worked in Spain until returning to Germany in 1955, servi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blacklisting
Blacklisting is the action of a group or authority compiling a blacklist of people, countries or other entities to be avoided or distrusted as being deemed unacceptable to those making the list; if people are on a blacklist, then they are considered to have done something wrong, or they are considered to be untrustworthy. As a verb, blacklist can mean to put an individual or entity on such a list. A blacklist is synonymous with a list of banned persons or organizations, and is the opposite of a whitelist. Origins of the term The English dramatist Philip Massinger used the phrase "black list" in his 1639 tragedy '' The Unnatural Combat''. After the restoration of the English monarchy brought Charles II of England to the throne in 1660, a list of regicides named those to be punished for the execution of his father. The state papers of Charles II say "If any innocent soul be found in this black list, let him not be offended at me, but consider whether some mistaken principle or ...

Messerschmitt Me 262
The Messerschmitt Me 262, nicknamed (German for "Swallow") in fighter versions, or ("Storm Bird") in fighter-bomber versions, is a fighter aircraft and fighter-bomber that was designed and produced by the German aircraft manufacturer Messerschmitt. It was the world's first operational jet-powered fighter aircraft and one of two jet fighter aircraft types to see air-to-air combat in World War Two, the other being the Heinkel He 162. The design of what would become the Me 262 started in April 1939, before World War II. It made its maiden flight on 18 April 1941 with a piston engine, and its first jet-powered flight on 18 July 1942. Progress was delayed by problems with engines, metallurgy Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys.

Jet Engine
A jet engine is a type of reaction engine, discharging a fast-moving jet (fluid), jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include Rocket engine, rocket, Pump-jet, water jet, and hybrid propulsion, the term typically refers to an internal combustion airbreathing jet engine, air-breathing jet engine such as a turbojet, turbofan, ramjet, pulse jet engine, pulse jet, or scramjet. In general, jet engines are internal combustion engines. Air-breathing jet engines typically feature a Axial compressor, rotating air compressor powered by a turbine, with the leftover power providing thrust through the propelling nozzle—this process is known as the Brayton cycle, Brayton thermodynamic cycle. Jet aircraft use such engines for long-distance travel. Early jet aircraft used turbojet engines that were relatively inefficient for subsonic flight. Most modern subsonic jet aircraft use more complex High-bypass turbofan, high-bypas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Flight Airspeed Record
An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), which also ratifies any claims. Speed records are divided into a number of classes with sub-divisions. There are three classes of aircraft: landplanes, seaplanes, and amphibious aircraft, amphibians, and within these classes there are records for aircraft in a number of weight categories. There are still further subdivisions for Reciprocating engine, piston-engined, turbojet, turboprop, and Rocket engine, rocket-engined aircraft. Within each of these groups, records are defined for speed over a straight course and for closed circuits of various sizes carrying various payloads. Timeline Gray text indicates unofficial records, including unconfirmed or unpublicized war secrets.

Messerschmitt Me 209
The first Messerschmitt Me 209 was a single-engine racing aircraft designed and produced by the German aircraft manufacturer Messerschmitt. It successfully established several new speed records. The design work on what was originally designated ''P.1059'' commenced in 1937; the Me 209 was a completely original aircraft whose sole purpose was to set new international speed records. As originally built, it has a relatively compact airframe, incorporated a steam cooling system, a unique cross-shaped tail section, and lacked any armaments. On 1 August 1938, ''Me 209 V1'' conducted its maiden flight; a further three prototypes would be completed by May 1939. On 26 April 1939, this same aircraft established a new international speed record of almost 756 km/h (469 mph); this record was not officially broken by another piston-engined aircraft until 16 August 1969. In addition to the ''Me 209'' designation, the type was also assigned the ''Me 109R'' designation for propaga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fighter Aircraft
Fighter aircraft (early on also ''pursuit aircraft'') are military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air supremacy, air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical bombing, tactical and strategic bombing of enemy targets, and helps prevent the enemy from doing the same. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground-attack aircraft, ground attack and some types, such as fighter-b ...

Messerschmitt Bf 109
The Messerschmitt Bf 109 is a monoplane fighter aircraft that was designed and initially produced by the Nazi Germany, German aircraft manufacturer Messerschmitt#History, Bayerische Flugzeugwerke (BFW). Together with the Focke-Wulf Fw 190, the Bf 109 formed the backbone of the ''Luftwaffe's'' fighter force during the World War II. It was commonly called the Me 109 by Allied aircrew and some German aces/pilots, even though this was not the official model designation. The Bf 109 was designed by Willy Messerschmitt and Robert Lusser, who worked at BFW during the early to mid-1930s. It was conceived as an interceptor aircraft, interceptor. However, later models were developed to fulfill multiple tasks, serving as Escort fighter, bomber escort, fighter-bomber, day fighter, day-, night fighter, night-, all-weather fighter, ground-attack aircraft, and aerial reconnaissance aircraft. It was one of the most advanced fighters when the fighter first appeared, being furnished with an all-me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
