Experimental Aircraft
An experimental aircraft is an aircraft intended for testing new aerospace technologies and design concepts. The term ''research aircraft'' or ''testbed aircraft'', by contrast, generally denotes aircraft modified to perform scientific studies, such as weather research or geophysical surveying, similar to a research vessel. United States The term "experimental aircraft" also has specific legal meaning in Australia, the United States and some other countries; usually used to refer to aircraft flown with an experimental certificate. In the United States, this also includes most homebuilt aircraft, many of which are based on conventional designs and hence are experimental only in name because of certain restrictions in operation.

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Akaflieg Berlin
''Akaflieg Berlin'' is one of around thirteen flying groups, or ''Akaflieg'', currently attached to German universities. ''Akaflieg Berlin'', is the abbreviation of ''Akademische Fliegergruppe Berlin e.V.'' (Academic Aviator Group Berlin), a group of students enrolled at several Berlin universities, though they are mainly from TU Berlin, who are involved with the development and the design of gliders, as well as research in aerodynamics. Founded in 1920 ''Akaflieg Berlin'' was founded in 1920 and is one of the oldest gliding clubs in Germany, flying their gliders from Kammermark airfield near Pritzwalk, which they share with the AFV Berlin (''Akademische Fliegervereinigung Berlin e.V''.), which mainly consists of former members of ''Akaflieg Berlin'', jokingly referred to as the “elderly ladies and gentlemen”. As at 2007/2008 Akaflieg Berlin was the executive group of the Idaflieg (''Interessengemeinschaft deutscher akademischer Fliegergruppen e.V.''), the controlling body f ...

Hirth HM 500
The Hirth HM 500 was a German four-cylinder air-cooled inverted inline engine developed from the Hirth HM 504 in 1938. Although developing the same output of the HM 504 (105 hp) and keeping the same capacity and bore, the HM 500 was a very different engine; the new HM 500 had a one-piece "closed" crankcase for simplified manufacture. The new cooling system reduced cylinder temperatures considerably (15 °C less), and the fuel consumption was also reduced. The HM 500 carried a twin-magneto instead of the two separate magnetos as on the old HM 504. All these changes made that the HM 500 resulted a 12% lighter than the HM 504 and the front surface 37% less than the previous HM 504.Flugmotor Hirth HM 500, Luftfahrt International Nr 6, Dec. 1974 Otherwise the HM 500 continued the typical Hirth use of built-up crankshafts and roller-bearings for crankshaft & connecting rods (Hirth patents) as well as magnesium-alloy crankcases which made Hirth engines so popular in the 193 ...

Gloster Meteor F8 "Prone Pilot"
A much modified Gloster Meteor F8 fighter, the "prone position/prone pilot" Meteor, was used by the Royal Air Force in 1954 and 1955 to evaluate the effects of acceleration/inertia-induced forces while flying in a prone position. Along with the Reid and Sigrist R.S.4 "Bobsleigh", the Gloster Meteor was engaged in a proof-of-concept experimental programme that proved in practice that the difficulties in rearward visibility and ejection outweighed the advantages of sustaining higher ''g'' effects. Design and development In the early 1950s the adoption of a prone position cockpit in future combat aircraft designs appeared attractive for two reasons. Firstly, such a configuration enabled the frontal area of the airframe to be reduced and therefore reduced drag. Secondly, aircrew can withstand greater inertial forces if not sitting upright, a vital consideration given the need for jet combat aircraft to manoeuvre at ever increasing speeds. While the Reid and Sigrist R.S.4 "Bobsleig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henschel Hs 132
Henschel's Hs 132 was a World War II dive bomber and interceptor aircraft of the German ''Luftwaffe'' that never saw service. The unorthodox design featured a top-mounted BMW 003 jet engine (identical in terms of make and position to the powerplant used by the Heinkel He 162) and the pilot in a prone position. The Soviet Army occupied the factory just as the Hs 132 V1 was nearing flight testing, the V2 and V3 being 80% and 75% completed. Design and development There had been interest in the idea of a prone pilot for combat aircraft to reduce the effect of ''g''-forces during maneuvering. Several aircraft had already experimented with this layout for various reasons, the Horten IIIf had a prone pilot, but this was primarily to reduce drag in this high-performance glider, while the DFS 228 reconnaissance glider also used a prone pilot to make it easier to seal its pressurized cabin. It was not until the Berlin B9 was built specifically to test this arrangement for improved ''g''- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ikarus 451
The Ikarus 451 is a family of research aircraft designs built in Yugoslavia in the 1950s, all sharing the same basic airframe, but differing in powerplants and cockpit arrangements. One member of the family Ikarus 451M became the first domestically-built jet aircraft to fly in Yugoslavia, on 25 October 1952. Design and development To research prone pilot cockpit arrangements and controls, the Government Aircraft Factories developed the Ikarus 232 Pionir, a small twin-engined low-wing monoplane, powered by 2x Walter Mikron III piston engines. An enlarged version of the Pionir was developed as the Type 451, powered by 2x Walter Minor 6-III piston engines. The first aircraft built under this designation was a propeller-driven aircraft that also accommodated the pilot in prone position. It was an otherwise conventional low-wing monoplane with retractable tailwheel undercarriage, the main units of which retracted backwards into the engine nacelles mounted below the wings. This f ...

Research And Development In Nazi Germany
Research is " creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, econom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prone Pilot Aircraft
Prone position () is a body position in which the person lies flat with the chest down and the back up. In anatomical terms of location, the dorsal side is up, and the ventral side is down. The supine position is the 180° contrast. Etymology The word ''prone'', meaning "naturally inclined to something, apt, liable," has been recorded in English since 1382; the meaning "lying face-down" was first recorded in 1578, but is also referred to as "lying down" or "going prone." ''Prone'' derives from the Latin ', meaning "bent forward, inclined to," from the adverbial form of the prefix ''pro-'' "forward." Both the original, literal, and the derived figurative sense were used in Latin, but the figurative is older in English. Anatomy In anatomy, the prone position is a position of the human body, body lying face down. It is opposed to the supine position which is face up. Using the terms defined in the anatomical position, the ventral side is down, and the dorsal side is up. Con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
