Hiro Type 14
The Hiro Type 14 engine, (full designation Hiro Type 14 500 hp water-cooled W-12), was a water-cooled twelve-cylinder W engine built by the Hiro Naval Arsenal (''Hiro Kaigun Ko-sho'') for the Imperial Japanese Navy. The Hiro Type 14 engine design was based on the Napier Lion. Like the parent engine, and the Lorraine 12 Eb, it had three banks of four cylinders each, with the center bank upright, and the other two banks angled outward 60 degrees. In some cases the W engine is referred to as the broad arrow configuration, due to its shape resembling the British government broad arrow property mark. The first aircraft to be powered by a Type 14 engine was the Hiro H2H flying boat. Design and development Japan's military leaders discovered the value of aircraft while participating in World War I.Mikesh and Abe p.10 It was necessary to import all of its military aircraft and engines as there was no aviation manufacturing industry in Japan at that time.

Reciprocating 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 ...

Supermarine Southampton
The Supermarine Southampton was a flying boat of the interwar period designed and produced by the British aircraft manufacturer Supermarine. It was one of the most successful flying boats of the era. The Southampton was derived from the experimental Supermarine Swan, and thus was developed at a relatively high pace. According to the aviation authors C. F. Andrews and E. B. Morgan, the design of the Southampton represented a new standard for maritime aircraft, and was a major accomplished for Supermarine's design team, headed by R. J. Mitchell.Andrews and Morgan 1981, p. 96. Demand for the type was such that Supermarine had to expand its production capacity to keep up. During August 1925, the Southampton entered service with the Royal Air Force (RAF), with whom the type gained a favourable reputation via a series of long-distance formation flights. Further customers emerged for the type, including the Imperial Japanese Navy, Argentine Naval Aviation, and Royal Danish Navy. Severa ...

Emperor Taishō
was the 123rd Emperor of Japan, according to the traditional order of succession, and the second ruler of the Empire of Japan from 30 July 1912 until his death in 1926. The Emperor's personal name was . According to Japanese custom, while reigning the Emperor is simply called "the Emperor". After death, he is known by a posthumous name, which is the name of the era coinciding with his reign. Having ruled during the Taishō era, he is known as the "Emperor Taishō". Early life Prince Yoshihito was born at the Tōgū Palace in Akasaka, Tokyo to Emperor Meiji and Yanagiwara Naruko, a concubine with the official title of ''gon-no-tenji'' (imperial concubine). As was common practice at the time, Emperor Meiji's consort, Empress Shōken, was officially regarded as his mother. He received the personal name of Yoshihito Shinnō and the title ''Haru-no-miya'' from the Emperor on 6 September 1879. His two older siblings had died in infancy, and he too was born sickly. Prince Yoshih ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Boat
A flying boat is a type of fixed-winged seaplane with a hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fuselage-mounted floats for buoyancy. Though the fuselage provides buoyancy, flying boats may also utilize under-wing floats or wing-like projections (called sponsons) extending from the fuselage for additional stability. Flying boats often lack landing gear which would allow them to land on the ground, though many modern designs are convertible amphibious aircraft which may switch between landing gear and flotation mode for water or ground takeoff and landing. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of the 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biplane
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 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. The term is also ...

Broad Arrow
A broad arrow, of which a pheon is a variant, is a stylised representation of a metal arrowhead, comprising a tang and two barbs meeting at a point. It is a symbol used traditionally in heraldry, most notably in England, and later by the British government to mark government property. It became particularly associated with the Board of Ordnance, and later the War Department and the Ministry of Defence. It was exported to other parts of the British Empire, where it was used in similar official contexts. In heraldry, the arrowhead generally points downwards, whereas in other contexts it more usually points upwards. In heraldry The broad arrow as a heraldic device comprises a socket tang with two converging blades, or barbs. When these barbs are engrailed on their inner edges, the device may be termed a ''pheon''. Woodward's ''Treatise on Heraldry: British and Foreign with English and French Glossaries'' (1892), makes the following distinction: "A BROAD ARROW and a PHEON are re ...

W Engine
A W engine is a type of piston engine where three or four cylinder banks use the same crankshaft, resembling the letter W when viewed from the front. W engines with three banks of cylinders are also called "broad arrow" engines, due to their shape resembling the British government broad arrow property mark. W engines are less common than V engines. Compared with a V engine, a W engine is typically shorter and wider. W3 engines One of the first W engines was the Anzani 3-cylinder, built in 1906, to be used in Anzani motorcycles. It is this W3 engine which also powered the 1909 Blériot XI, the first airplane to fly across the English Channel. The ''Feuling W3'' is a motorcycle engine that was built by an aftermarket parts company in the United States in the early 2000s. Like radial aircraft engines it has a master connecting rod and two slave rods connected to the pistons.

Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery. ...
