Berg Fighter
The Aviatik (Berg) D.I, was a single-engine, single-seater biplane fighter that was developed and manufactured by the Austro-Hungarian branch of German aircraft company Aviatik. It was also known as Berg D.I or the ''Berg Fighter'', because it was designed by Dipl. Ing. Julius von Berg, and to distinguish it from the D.I fighter built by the parent Aviatik firm in Germany. The D.I was the first locally designed fighter aircraft to be adopted into the Austro-Hungarian Air Service (''Luftfahrtruppen'').The German parent company of Aviatik built the Halberstadt D.II under licence as the Aviatik D.I. This was later redesignated Halberstadt D.II(Av) when the German military changed its nomenclature, however the D.I designation was never reused. The Aviatik (Berg) D.I designation was in a different sequence, used by the Austro-Hungarian military. It was manufactured both in-house and under license by a number of subcontractors. In 1917, the D.I entered Austro-Hungarian service and s ... [...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 ...

Bulkhead (partition)
A bulkhead is an upright wall within the hull of a ship or within the fuselage of an airplane. Other kinds of partition elements within a ship are decks and deckheads. Etymology The word ''bulki'' meant "cargo" in Old Norse. During the 15th century sailors and builders in Europe realized that walls within a vessel would prevent cargo from shifting during passage. In shipbuilding, any vertical panel was called a head. So walls installed abeam (side-to-side) in a vessel's hull were called "bulkheads". Now, the term bulkhead applies to every vertical panel aboard a ship, except for the hull itself. History Bulkhead partitions are considered to have been a feature of Chinese junks, a type of ship. Song Dynasty author Zhu Yu (fl. 12th century) wrote in his book of 1119 that the hulls of Chinese ships had a bulkhead build. The 5th-century book ''Garden of Strange Things'' by Liu Jingshu mentioned that a ship could allow water to enter the bottom without sinking. Archaeolo ...

Longeron
In engineering, a longeron and stringer is the load-bearing component of a framework. The term is commonly used in connection with aircraft fuselages and automobile chassis. Longerons are used in conjunction with stringers to form structural frameworks. Aircraft In aircraft fuselage, stringers are attached to formers (also called frames) and run in the longitudinal direction of the aircraft. They are primarily responsible for transferring the aerodynamic loads acting on the skin onto the frames and formers. In the wings or horizontal stabilizer, longerons run spanwise (from wing root to wing tip) and attach between the ribs. The primary function here also is to transfer the bending loads acting on the wings onto the ribs and spar. Sometimes the terms "longeron" and "stringer" are used interchangeably. Historically, though, there is a subtle difference between the two terms. If the longitudinal members in a fuselage are few in number (usually 4 to 8) and run all along the ...

Imperial And Royal Aviation Troops
The Austro-Hungarian Aviation Troops or Imperial and Royal Aviation Troops (german: Kaiserliche und Königliche Luftfahrtruppen or , hu, Császári és Királyi Légjárócsapatok) were the air force of the Austro-Hungarian Empire until the empire's demise in 1918; it saw combat on both the Eastern Front and Italian Front during World War I. History The Air Service began in 1893 as a balloon corps () and would later be re-organized in 1912 under the command of Major Emil Uzelac, an army engineering officer. The Air Service would remain under his command until the end of World War I in 1918. The first officers of the air force were private pilots with no military aviation training. At the outbreak of war, the Air Service was composed of 10 observation balloons, 85 pilots and 39 operational aircraft. By the end of 1914, there were 147 operational aircraft deployed in 14 units. Just as Austria-Hungary fielded a joint army and navy, they also had army and naval aviation arm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiator
Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in cars, buildings, and electronics. A radiator is always a source of heat to its environment, although this may be for either the purpose of heating this environment, or for cooling the fluid or coolant supplied to it, as for automotive engine cooling and HVAC dry cooling towers. Despite the name, most radiators transfer the bulk of their heat via convection instead of thermal radiation. History The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, having received a radiator patent in 1857, but American Joseph Nason developed a primitive radiator in 1841 and received a number of U.S. patents for hot water and steam heating. ...

Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austro-Daimler
Austro-Daimler was an Austro-Hungarian automaker company, from 1899 until 1934. It was a subsidiary of the German ''Daimler-Motoren-Gesellschaft'' (DMG) until 1909. Early history In 1890, Eduard Bierenz was appointed as Austrian retailer. The company sold so well that it also began manufacturing the automobiles after uniting with Eduard Fischer's engineering factory. The works were located at Wiener-Neustadt. By this subsidiary ''DMG'' became the first automotive multinational in history. Thus on August 11, 1899, the Austrian Daimler Engine Society was founded. Whilst the assembling parts stemmed from Stuttgart, in 1900 they built their first automobile which featured 2 cylinders, , and 4 seats. Soon they started producing engines for luxurious cars, trucks, buses, maritime ships, and trains. Paul Daimler era In 1902, Paul Daimler, Gottlieb Daimler's son, took charge of the Technical Department. He developed a compact car (8 hp, 45 km/h). In 1905 he built the company ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Bou ...
