Avia BH-25
__NOTOC__ The Avia BH-25 was a biplane airliner built in Czechoslovakia in 1926. Typical of airliners of its time, it seated five passengers within its fuselage, whilst the pilots sat in an open cockpit above. Of conventional configuration, it was a single-bay bi-plane of equal span and unstaggered wings, with fixed Conventional landing gear, tailskid landing gear. Originally designed for a Lorraine-Dietrich Piston engine, engine, this was changed to a Bristol Jupiter in service. After their withdrawal from airline use in 1936, some were used by the military for a while before finally becoming training targets.

Cockpit
A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a Pilot in command, pilot controls the aircraft. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin. After the September 11 attacks, September 11, 2001 attacks, all major airlines Airport_security_repercussions_due_to_the_September_11_attacks#Improved_security_on_aircraft, fortified their cockpits against access by aircraft hijacking, hijackers. Etymology The word cockpit seems to have been cockpit (sailing), used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore.

Avia Motors s.r.o. is a Czech automotive manufacturer. It was founded in 1919 as an aircraft maker, and diversified into trucks after 1945. As an aircraft maker it was notable for producing biplane fighter aircraft, especially the B-534. Avia ceased aircraft production in 1963. History The company was founded by Pavel Beneš, Miroslav Hajn, Jaroslav František Koch and Václav Malý in 1919 and became part of Škoda Works a.s. in 1928. During the 1930s the factory became the biggest aircraft producer in Czechoslovakia and moved to Letňany near Prague, where production continues until today. During the Nazi occupation Avia made aircraft for the German Luftwaffe. After the war the company was nationalized and became involved in the automotive industry. It made aircraft until 1963, then concentrated on truck production and continued to make aircraft engines (producing only propellers from 1988). The company was split in 1992 into propeller and truck sections, both usi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Romanian Air Force
The Air Force branch of the Royal Romanian forces in World War II was officially named the (ARR), or the Romanian Royal Aeronautics, though it is more commonly referred to in English histories as the (Royal Romanian Air Force, FARR), or simply (Romanian Air Force). It provided support to land forces, carrying out reconnaissance and mounting air raids between other missions. Insignia The roundel of the ARR was based on the national cockade of Romania. During World War Two, from 1941 to 1944, the national cockade was reduced in size and placed in the center of a four-M cross, the seal of King Michael I of Romania. These crosses came in different types and sizes as there was no standard model. The markings were placed on the fuselage as well as on the upper and lower wings, and the national colours were painted on the tail. According to Axis regulations, the engine cowling, the under-surfaces of the wingtips and a vertical band on the fuselage ahead of the tail were painted in yello ...

Bristol Jupiter
The Bristol Jupiter was a British nine-cylinder single-row piston radial engine built by the Bristol Aeroplane Company. Originally designed late in World War I and known as the Cosmos Jupiter, a lengthy series of upgrades and developments turned it into one of the finest engines of its era. The Jupiter was widely used on many aircraft designs during the 1920s and 1930s. Thousands of Jupiters of all versions were produced, both by Bristol and abroad under licence. A turbo-supercharged version of the Jupiter known as the Orion suffered development problems and only a small number were produced. The "Orion" name was later re-used by Bristol for an unrelated turboprop engine. Design and development The Jupiter was designed during World War I by Roy Fedden of Brazil Straker and later Cosmos Engineering. The first Jupiter was completed by Brazil Straker in 1918 and featured three carburettors, each one feeding three of the engine's nine cylinders via a spiral deflector housed ins ...

Piston Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intro ...

Lorraine-Dietrich
Lorraine-Dietrich was a French automobile and aircraft engine manufacturer from 1896 until 1935, created when railway locomotive manufacturer ''Société Lorraine des Anciens Etablissements de Dietrich et Cie de Lunéville'' (known as ''De Dietrich et Cie'', founded in 1884 by Jean de Dietrich) branched into the manufacture of automobiles. The Franco-Prussian War divided the company's manufacturing capacity, one plant in Niederbronn-les-Bains, Alsace, the other in Lunéville, Lorraine. Beginnings In 1896, managing director of the Lunéville plant, Baron Adrien de Turckheim, bought the rights to a design by Amédée Bollée. This used a front-mounted horizontal twin engine with sliding clutches and belt drive. It had a folding top, three acetylene headlights, and, very unusual for the period, plate glass windshield. While the company started out using engines from Bollée, De Dietrich eventually produced the entire vehicle themselves. In 1898, De Dietrich debuted the ''Torpi ...

Conventional Landing Gear
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
