Standard H-3
The Standard H-2 was an early American Army reconnaissance aircraft, ordered in 1916. The H-2 was built by the Standard Aircraft Corporation, and previously known as the Sloane H-2. It was an open-cockpit three-place tractor biplane, powered by a 125 hp (90 kW) Hall-Scott A-5 engine. Only three were built. An improved version, the H-3, with the same engine, earned an order for nine aircraft, while the Navy ordered three with floats as the H-4H. Two Standard H-3s were sold by the US Army to Japan, where a further three were built by the Provisional Military Balloon Research Association (PMBRA) in 1917, powered by Hall-Scott L-4 engines. They were used as trainers between May 1917 and March 1918, although they were considered dangerous.Mikesh and Abe 1990, p. 55.

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

1910s United States Military Reconnaissance Aircraft
Year 191 ( 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. Events By place Parthia * King Vologases IV of Parthia dies after a 44-year reign, and is succeeded by his son Vologases V. China * A coalition of Chinese warlords from the east of Hangu Pass launches a punitive campaign against the warlord Dong Zhuo, who seized control of the central government in 189, and held the figurehead Emperor Xian hostage. After suffering some defeats against the coalition forces, Dong Zhuo forcefully relocates the imperial capital from Luoyang to Chang'an. Before leaving, Dong Zhuo orders his troops to loot the tombs of the Han emperors, and then destroy Luoyang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ...

Aviation Week & Space Technology
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network, a division of Informa. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960. Other titles the magazine has held inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hall-Scott A-5
Hall-Scott Motor Car Company was an American manufacturing company based in Berkeley, California. It was among the most significant builders of water-cooled aircraft engines before World War I. History 1910–21 The company was founded in 1910 by Californians Elbert J. Hall and Bert C. Scott to manufacture engines for automobiles and later expanded the production of engines for trucks and airplanes as well as gasoline-powered rail cars and locomotives. Hall was a mechanic and engine builder and Scott, Stanford University-educated, was the business executive. They produced their first rail car in 1909, which they sold to the Yreka Railroad. In 1910, a factory was opened in Berkeley, California, with headquarters for a short time in San Francisco. The company built interurban electric railway cars for railroads such as the electrified Sacramento Northern, which ran trains from adjacent Oakland to Sacramento and Chico. The rail car business was slow, but some were sold as far a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is one of the six armed forces and one of the eight uniformed services of the United States. The Army is the most senior branch in order of precedence amongst the armed services. It has its roots in the Continental Army, formed on 14 June 1775 to fight against the British for independence during the American Revolutionary War (1775–1783). After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals ...

Imperial Japanese Navy Air Service
The (IJNAS) was the air arm of the Imperial Japanese Navy (IJN). The organization was responsible for the operation of naval aircraft and the conduct of aerial warfare in the Pacific War. The Japanese military acquired its first aircraft in 1910 and followed the development of air combat during World War I with great interest. Japan initially built European aircraft under license, but by the early 1930s Japanese factories were producing domestic designs. The Japanese also embarked on an ambitious aircraft carrier building program, launching the world's first purpose-built aircraft carrier, , in 1922. Several excess battlecruisers and battleships were converted into aircraft carriers as well. As the organization assigned to the IJN's aircraft carriers, the Navy Air Service was tasked with the missions of national air defence, deep strike, naval warfare, and so forth. It retained this mission until its dissolution at the end of the Second World War. The Japanese pilot training ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Float (nautical)
A float (also called a pontoon) is an airtight hollow structure, similar to a pressure vessel, designed to provide buoyancy in water. Its principal applications are in hull (watercraft), watercraft hulls, Floatplane, aircraft floats, Floating dock (jetty), floating piers, aquaculture, pontoon bridge, pontoon bridges, and marine engineering applications such as marine salvage, salvage. Applications Floats make up the multipart hulls of catamarans and trimarans and provide buoyancy for floatplanes, seaplanes and houseboats. They are used in pontoon bridges, floating piers, and floats anchored to the seabed for recreation or dockage. They are also used in shipbuilding and marine salvage, often deployed uninflated then pressurized to raise a sunken object. In military, floats are used as pontoon bridges or transportation platforms for heavier vehicles or machinery. In popular usage, the term ''pontoon'' can refer to any of several of the following objects that make use of nautical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
