The Akaflieg Berlin B 9 was a twin-engined experimental aircraft, developed by Akaflieg Berlin and Flugtechnische Fachgruppe in the 1940s. It was designed to examine the benefits of having a pilot in a prone position Prone position () is a body position in which the person lies flat with the chest down and the back up.

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. 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. , US Federal Aviation Administration.

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'' 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 for all German universit ...

Prone Position
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 ', 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 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. Concerning the forea ...

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 heavily 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 "Bobs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henschel Hs 132
The Henschel Hs 132 was a jet-powered dive bomber and interceptor aircraft designed and produced by the German aircraft manufacturer Henschel Flugzeugwerke AG. It was developed during the latter portion of the Second World War with the intention of being adopted by the ''Luftwaffe'', but this did not come to fruition. Work commenced on the Hs 132 in February 1943 in response to a specification issued by the '' Reichsluftfahrtministerium'' (RLM – the German Aviation Ministry) for a new attack aircraft. Henschel opted for a relatively unorthodox design that, amongst other features, used a top-mounted BMW 003 jet engine (identical in terms of make and position to the powerplant used by the Heinkel He 162), a retractable nosewheel undercarriage and the pilot in a prone position. The aircraft intentionally made as little use of strategic materials as possible, such as its use of wooden wings, and had a relatively simplistic structure despite it being designed to withstand 1 ...

Ikarus 451
The Ikarus 451 is a family of research aircraft designs built in the former Yugoslavia in the 1950s by the Belgrade-based manufacturer Ikarus (now Ikarbus), 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. It was succeeded by the Ikarus 452. Design, development, and variants To research prone pilot cockpit arrangements and controls, the Yugoslav Government Aircraft Factories developed the Ikarus 232 Pionir, a small twin-engined low-wing monoplane, powered by 2x Walter Mikron III piston engines. Type 451 An enlarged version of the Pionir was developed as the Type 451, powered by 2x Walter Minor 6-III six-cylinder piston engines of each. The Type 451 had a 6.7 m (22 ft) wingspan, a maximum speed of 335 km/h (182 knots), and a ceiling of 4750 m (15,570 ft). It first flew in 1952. It ...

List Of Aircraft Of World War II
The list of aircraft of World War II includes all of the aircraft used by countries which were at war during World War II from the period between when the country joined the war and the time the country withdrew from it, or when the war ended. Aircraft developed but not used operationally in the war are in the prototypes section at the bottom of the page. Prototypes for aircraft that entered service under a different design number are ignored in favor of the version that entered service. If the date of an aircraft's entry into service or first flight is not known, the aircraft will be listed by its name, the country of origin or major wartime users. Aircraft used for multiple roles are generally only listed under their primary role unless specialized versions were built for other roles in significant numbers. Aircraft used by neutral countries such as Spain, Switzerland and Sweden (or countries which did no significant fighting such as most of those in South America) are not include ...

1940s German Experimental Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday 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.
