Lippisch P.11
The Lippisch Delta VI was a proposed single-seat, twin-jet experimental delta flying wing aircraft begun in 1943 by German designer Alexander Lippisch, as the developed version of the P.11 bomber project begun while he was still working for Messerschmitt in 1942. The only prototype was destroyed in June 1944 while still under construction. Design and development P.11 bomber for Messerschmitt During 1942, while still working on the Messerschmitt Me 163 rocket fighter, Alexander Lippisch conceived a larger but similarly tailless bomber with twin jet engines buried in a thick wing, designated P.11.Sharp (2015), pp.108-111. P.11 flying-wing fighter Following his departure for his own independent design office near Vienna in Austria, Lippisch returned to the P.11 and radically revised it. The fuselage shrank to a short forward cockpit nacelle. The engines were placed quite close together inside the wing, with intakes in the roots and the otherwise straight trailing edge cut back for ...

Alexander Lippisch
Alexander Martin Lippisch (November 2, 1894 – February 11, 1976) was a German aeronautical engineer, a pioneer of aerodynamics who made important contributions to the understanding of tailless aircraft, delta wings and the ground effect, and also worked in the U.S. Within the Opel-RAK program, he was the designer of the world's first rocket-powered glider. He developed and conceptualized delta wing designs which functioned practically in supersonic delta wing fighter aircraft as well as in hang gliders. People he worked with continued the development of the delta wing and supersonic flight concepts over the 20th century. His most famous designs are the Messerschmitt Me 163 rocket-powered interceptorReitsch, H., 1955, The Sky My Kingdom, London: Biddles Limited, Guildford and King's Lynn, and the Dornier Aerodyne. Early life Lippisch was born in Munich, Kingdom of Bavaria. He later recalled that his interest in aviation began with a demonstration conducted by Orville Wright ...

Junkers Jumo 004
The Junkers Jumo 004 was the world's first production turbojet engine in operational use, and the first successful axial compressor turbojet engine. Some 8,000 units were manufactured by Junkers in Germany late in World War II, powering the Messerschmitt Me 262 fighter and the Arado Ar 234 reconnaissance/bomber, along with prototypes, including the Horten Ho 229. Variants and copies of the engine were produced in Eastern Europe and the USSR for several years following the end of WWII. Design and development The feasibility of jet propulsion had been demonstrated in Germany in early 1937 by Hans von Ohain working with the Heinkel company. Most of the Reich Air Ministry ( RLM) remained uninterested, but Helmut Schelp and Hans Mauch saw the potential of the concept and encouraged Germany's aero engine manufacturers to begin their own programmes of jet engine development. The companies remained skeptical and little new development was carried out. In 1939 Schelp and Mauch visited th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jet Aircraft
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound. Jet aircraft generally cruise most efficiently at about Mach 0.8 () and at altitudes around or more. The idea of the jet engine was not new, but the technical problems involved could not begin to be solved until the 1930s. Frank Whittle, an English inventor and RAF officer, began development of a viable jet engine in 1928, and Hans von Ohain in Germany began work independently in the early 1930s. In August 1939 the turbojet powered Heinkel He 178, the world's first jet aircraft, made its first flight. A wide range of different types of jet aircraft exist, both for civilian and military purposes. History After the first instance of powered f ...

1940s German Experimental Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria. Pescennius retreats to Antioch, and is executed by Severus' troops. * Septimius Severus besieges Byzantium (194–196); the city walls suffer extensive damage.

List Of World War II Military Aircraft Of Germany
This list covers aircraft of the German Luftwaffe during the Second World War from 1939 to 1945. Numerical designations are largely within the RLM designation system. The Luftwaffe officially existed from 1933–1945 but training had started in the 1920s, before the Nazi seizure of power, and many aircraft made in the inter-war years were used during World War II. The main list highlights the most significant aircraft that participated and includes minor types. Pre-war aircraft not used after 1938 are excluded, as are projects and aircraft that did not fly. Listed roles are those for which the aircraft were being used during the war – many obsolete pre-war combat aircraft remained in use as trainers rather than in their original more familiar roles. Captured or acquired aircraft are listed separately as many were used only for evaluation while those available in large enough numbers were commonly used as trainers, while a small number were usen the Reich Aviation Ministry's list ...

List Of Military Aircraft Of Germany
This list of military aircraft of Germany includes prototype, pre-production, and operational types. No distinction is drawn here between different services until 1991. In 1990, the various air arms of the former German Democratic Republic were absorbed by their counterparts in the Federal Republic of Germany. Some types that had been operated by the GDR were no longer in service by then, and these are so noted.

Horten Ho 229
The Horten H.IX, RLM designation Ho 229 (or Gotha Go 229 for extensive re-design work done by Gotha to prepare the aircraft for mass production) was a German prototype fighter/bomber initially designed by Reimar and Walter Horten to be built by Gothaer Waggonfabrik. Developed at a late stage of the Second World War, it was the first flying wing to be powered by jet engines.Green 1970, p. 247. The Ho 229 had been designed in response to a call by Hermann Göring, the head of the Luftwaffe, in 1943 for light bomber designs capable of meeting the "3×1000" requirement; namely, to carry of bombs a distance of with a speed of . Only jet propulsion was capable of achieving the required speed, but such engines were relatively primitive and extremely fuel-hungry, necessitating considerable effort across the rest of the design in order to satisfy the range requirement as well. The flying wing configuration was favoured by the Horten brothers due to its high aerodynamic efficiency, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USAF
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control.

Tailless Aircraft
In aeronautics, a tailless aircraft is an aircraft with no other horizontal aerodynamic surface besides its main wing. It may still have a fuselage, vertical tail fin (vertical stabilizer), and/or vertical rudder. Theoretical advantages of the tailless configuration include low parasitic drag as on the Horten H.IV soaring glider and good stealth characteristics as on the Northrop B-2 Spirit bomber. Disadvantages include a potential sensitivity to trim. Tailless aircraft have been flown since the pioneer days; the first stable aeroplane to fly was the tailless Dunne D.5, in 1910. The most successful tailless configuration has been the tailless delta, especially for combat aircraft, though the most familiar tailless delta is the Concorde airliner. NASA has used the 'tailless' description for the novel X-36 research aircraft which has a canard foreplane but no vertical fin. Aircraft configuration A tailless aircraft has no other horizontal surface besides its main wing. The aer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
