JN-6 Jenny
The Curtiss JN-6H (Model 1F) was an American biplane trainer aircraft built by Curtiss for the United States Army Air Service during World War I. Design and development Developed from the one-off JN-5H advanced trainer, the 6H had a superior aileron operation mechanism. It was used in a variety of roles, with stick and rudder in either one seat or both: JN-6HB single-control bomber trainer (154 built), JN-6HG-1 dual-control gunnery trainer (560 built), JN-6HG-2 single-control gunnery trainer (90 built), JN-6HO single-control observation trainer (106 built),and JN-6HP single-control pursuit trainer (125 built), a total of 1,035; five went to the Navy.Fitzsimons 1978, p. 1502. The airframe did not differ substantially from the JN-4H (Model 1E), and used the same 150 hp (112 kW) Hispano-Suiza 8A ("Hisso") V8, which weighed 408 lb (185 kg).Hispano-Suiza 8A. Some of the aircraft were modernized as the Curtiss JNH and later to the Curtiss JNS (JN Standard) wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Curtiss JN-4
The Curtiss JN "Jenny" is a series of biplanes built by the Glenn Curtiss Aeroplane Company of Hammondsport, New York, later the Curtiss Aeroplane and Motor Company. Although the Curtiss JN series was originally produced as a training aircraft for the US Army, the "Jenny" (the common nickname derived from "JN") continued after World War I as a civilian aircraft, becoming the "backbone of American postwar ivilaviation". Thousands of surplus Jennys were sold at bargain prices to private owners in the years after the war, and became central to the barnstorming era that helped awaken the US to civil aviation through much of the 1920s. Design and development Curtiss combined the best features of the model J and model N trainers, built for the US Army and US Navy, and began producing the JN or "Jenny" series of aircraft in 1915. Curtiss built only a limited number of the JN-1 and JN-2 biplanes. The design was commissioned by Glenn Curtiss from Englishman Benjamin Douglas Thom ...

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag (aerodynamics), drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. ...

Curtiss Aircraft
The Curtiss Aeroplane and Motor Company (1909–1929) was an American aircraft manufacturer originally founded by Glenn Hammond Curtiss and Augustus Moore Herring in Hammondsport, New York. After significant commercial success in its first decades, it merged with the Wright Aeronautical to form Curtiss-Wright Corporation. History Origin In 1907, Glenn Curtiss was recruited by the scientist Dr. Alexander Graham Bell as a founding member of Bell's Aerial Experiment Association (AEA), with the intent of establishing an aeronautical research and development organization. According to Bell, it was a "co-operative scientific association, not for gain but for the love of the art and doing what we can to help one another."Milberry 1979, p 13. In 1909, shortly before the AEA was disbanded, Curtiss partnered with Augustus Moore Herring to form the Herring-Curtiss Company.Gunston 1993, p. 87. It was renamed the Curtiss Aeroplane Company in 1910 and reorganized in 1912 after being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1910s United States Military Trainer Aircraft
Year 191 (Roman numerals, CXCI) was a common year starting on Friday of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 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.

Water-cooled
Cooling tower and water discharge of a nuclear power plant Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power stations. Water coolers utilising convective heat transfer are used inside high-end personal computers to lower the temperature of CPUs and other components. Other uses include the cooling of lubricant oil in pumps; for cooling purposes in heat exchangers; for cooling buildings in HVAC and in chillers. Mechanism Advantages Water is inexpensive, non-toxic, and available over most of the earth's surface. Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmosph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V8 Engine
A V8 engine is an eight- cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. Origins The first known V8 was the Antoinette, designed by Léon Levavasseur, and built in 1904 by the French Antoinette company for use in speedboat racing, cars, and later, airplanes. Also in 1904, V8 engines began small-scale production by Renault and Buchet for use in race cars. Design V-angle Most engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations. However, the downside is the greater width of the engine compared to those that use a smaller V-angle. V8 engines with a 60-degree V-angle were used in the 1996–1999 Ford Taurus SHO, the 2005–2011 Volvo XC90, and the 2006–2009 Volvo S80. The Ford engine used a 60-degree V-angle because it was based on a V6 engine with a 60-degree V-angle. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hispano-Suiza 8
The Hispano-Suiza 8 is a Internal combustion engine cooling, water-cooled V8 engine, V8 SOHC aero engine introduced by Hispano-Suiza in 1914 that went on to become the most commonly used liquid-cooled engine in the aircraft of the Entente Powers during the First World War. The original Hispano-Suiza 8A was rated at and the later, larger displacement Hispano-Suiza 8F reached . Hispano-Suiza 8 engines and variants produced by Hispano-Suiza and other companies under licence were built in twenty-one factories in Spain, France, Britain, Italy, and the U.S. Derivatives of the engine were also used abroad to power numerous aircraft types and the engine can be considered as the ancestor of another successful engine by the same designer, the Hispano-Suiza 12Y (and Soviet Klimov V12 derivative aero-engines) which was in service during the Second World War. Design and development Origins At the beginning of World War I, the production lines of the Barcelona based Hispano-Suiza automobil ...

Artillery Spotting
An artillery observer, artillery spotter, or forward observer (FO) is a soldier responsible for directing artillery and mortar fire support onto a target. An artillery observer usually accompanies a tank or infantry unit. Spotters ensure that indirect fire hits targets which those at a fire support base cannot see. History Historically, the range of artillery steadily increased over the centuries. In the era of bombards or ''Steinbüchse'', the gunner could usually still fire directly on the target by line-of-sight. As ranges increased, methods of employing indirect fire were developed. This made a forward observer essential in order to be able to use artillery effectively. The proximity of the observer to the target depended on the terrain and battlefield situation. Elevated observation posts could be used as an aid to facilitate communication between the guns and the observers. The development of optical and communication aids for observation advanced significantly in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
