Karl Urban (aviator)
Karl Urban (29 December 1894 – 12 July 1918) was an Austro-Hungarian World War I flying ace credited with five aerial victories. Urban joined the Austro-Hungarian military as war broke out in 1914, volunteering for pilot's school as soon as he finished recruit training. In mid-July 1915, he was posted to the Russian Front as an aerial reconnaissance and bombing pilot. Between 15 May and 2 August 1916, Urban and his various observers—including Otto Jäger—were credited with four victories. On 28 August 1916, Urban was severely wounded in action but, after recovering, progressed to flying a Phönix D.I, gaining his fifth and final victory on 19 May 1918. Transferred to test pilot duty, Urban was looping a new model Phönix D.I on 12 July 1918, when it shed its wings at 1,500 meters altitude. The subsequent crash killed him. Early life and service Karl Urban was born in Graz, Austria on 29 December 1894, when it was still part of the Austro-Hungarian Empire. When World Wa ...

Military Intelligence
Military intelligence is a military discipline that uses information collection and analysis approaches to provide guidance and direction to assist commanders in their decisions. This aim is achieved by providing an assessment of data from a range of sources, directed towards the commanders' mission requirements or responding to questions as part of operational or campaign planning. To provide an analysis, the commander's information requirements are first identified, which are then incorporated into intelligence collection, analysis, and dissemination. Areas of study may include the operational environment, hostile, friendly and neutral forces, the civilian population in an area of combat operations, and other broader areas of interest. Intelligence activities are conducted at all levels, from tactical to strategic, in peacetime, the period of transition to war, and during a war itself. Most governments maintain a military intelligence capability to provide analytical and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noncommissioned Officer
A non-commissioned officer (NCO) is a military officer who has not pursued a commission. Non-commissioned officers usually earn their position of authority by promotion through the enlisted ranks. (Non-officers, which includes most or all enlisted personnel, are of lower rank than any officer.) In contrast, commissioned officers usually enter directly from a military academy, officer candidate school (OCS), or officer training school (OTS) after receiving a post-secondary degree. The NCO corps usually includes many grades of enlisted, corporal and sergeant; in some countries, warrant officers also carry out the duties of NCOs. The naval equivalent includes some or all grades of petty officer. There are different classes of non-commissioned officers, including junior (lower ranked) non-commissioned officers (JNCO) and senior/staff (higher ranked) non-commissioned officers (SNCO). Function The non-commissioned officer corps has been referred to as "the backbone" of the armed se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hanriot HD-1 (7108410371)
The Hanriot HD.1 was a French World War I single-seat fighter aircraft. Rejected for service with French squadrons in favour of the SPAD S.VII, the type was supplied to the Belgian Army′s (Belgian Military Aviation) and the (Military Aviation Corps) of the Royal Italian Army, with both of which it proved highly successful. Of a total of about 1,200 examples built, 831 were produced by Italian companies under licence. Development and production The Hanriot company produced a series of pioneering monoplanes pre-war but had settled down as a licence manufacturer, notably of Sopwith 1½ strutters, when the HD.1 was produced in 1916. The type was a conventional fighter with the general characteristics of a typical Sopwith aircraft, being strongly but lightly built and combining clean lines with a light wing loading. It used the same "1½" (or "W") cabane strut arrangement as the Sopwith two-seater. It had a flat lower wing, though the top wing had quite sharp dihedral.Chees ...

Hanriot HD
Aéroplanes Hanriot et Cie. or simply 'Hanriot' was a French aircraft manufacturer with roots going back to the beginning of aviation. Founded by René Hanriot in 1910 as ''The Monoplans Hanriot Company Ltd.'' the company survived in different forms until 1916 when it established itself with the Hanriot-Dupont (HD.) fighters and observation aircraft. The company lasted through several takeovers and structural changes until in 1936 it merged with Farman to become the Société Nationale de Constructions Aéronautiques du Centre (SNCAC). 'Central Air Works' consortium. Hanriot aeroplanes included pre-war monoplanes with boat-like fuselages, the HD.1 and 2 World War I biplane fighters, the HD.14 trainer, and the H.220 series of twin-engined heavy fighters that eventually evolved in the SNCAC 600 fighter just before World War II. The company's main bases of operations were Bétheny (a suburb of Reims) Boulogne-Billancourt, Carrières-sur-Seine and Bourges. History René Hanri ...

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] |
Nieuport
Nieuport, later Nieuport-Delage, was a French aeroplane company that primarily built racing aircraft before World War I and fighter aircraft during World War I and between the wars. History Beginnings Originally formed as Nieuport-Duplex in 1902 for the manufacture of engine components the company was reformed in 1909 as the Société Générale d'Aéro-locomotion, and its products were marketed to the aviation industry, including ignition components. During this time they built their first aircraft, a small single-seat pod and boom monoplane. This was destroyed shortly after having been flown successfully, during the Great Flood of Paris in 1909 . A second design flew before the end of 1909 and had the essential form of modern aircraft, including an enclosed fuselage with the pilot protected from the slipstream and a horizontal tail whose aerodynamic force acted downwards, balancing the weight of the engine ahead of the centre of gravity, as opposed to upwards as on contemp ...

Farman
Farman Aviation Works (french: Avions Farman) was a French aircraft company founded and run by the brothers Richard, Henri, and Maurice Farman. They designed and constructed aircraft and engines from 1908 until 1936; during the French nationalization and rationalization of its aeronautical industry, Farman's assets were assigned to the ''Société Nationale de Constructions Aéronautiques du Centre'' (SNCAC). In 1941 the Farman brothers reestablished the firm as the "''Société Anonyme des Usines Farman''" (SAUF), but only three years later it was absorbed by Sud-Ouest. Maurice's son, Marcel Farman, reestablished the SAUF in 1952, but his effort proved unsuccessful and the firm was dissolved in 1956. The Farman brothers designed and built more than 200 types of aircraft between 1908 and 1941. They also built cars until 1931 and boats until 1930. Background In 1907, Henri Farman bought his first aircraft from Gabriel Voisin and soon began to improve the design of the air ...

Valve Train
A valvetrain or valve train is a mechanical system that controls the operation of the intake and exhaust valves in an internal combustion engine. The intake valves control the flow of air/fuel mixture (or air alone for direct-injected engines) into the combustion chamber, while the exhaust valves control the flow of spent exhaust gasses out of the combustion chamber once combustion is completed. Layout The valvetrain layout is largely dependent on the location of the camshaft. The common valvetrain configurations for piston engines - in order from oldest to newest - are: * Flathead engine: The camshaft and the valves are located in the engine block below the combustion chamber. * Overhead valve engine: The camshaft remains in the block, however the valves are located in the cylinder head above the combustion chamber. * Overhead camshaft engine: The valves and camshaft(s) are in the cylinder head above the combustion chamber. Components The valvetrain consists of all the compo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
