Hiro H2H
The Hiro H2H, or "Navy Type 89 Flying boat" ( ja, "八九式飛行艇"), was a Japanese patrol flying boat of the 1930s. Designed and built by the Hiro Naval Arsenal, it was a twin-engined biplane that was operated by the Imperial Japanese Navy. Design and development In 1929, the Imperial Japanese Navy purchased a single example of the British Supermarine Southampton II metal-hulled flying boat,Andrews and Morgan 1987, p.110. and after evaluation, it was passed onto the Hiro Naval Arsenal (who designed the wooden Hiro H1H flying boat based on the Felixstowe F.5), to study its advanced metal hull structure. Following this study, Hiro designed a new flying boat, closely resembling the Southampton.Mikesh and Abe 1990, pp. 95-96. The new aircraft was a twin-engined biplane, with an all-metal hull, and fabric covered metal wing and tail structures. It was powered by two Hiro Type 14 water-cooled 12-cylinders W engines. The first prototype was completed in 1930, and following succe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Japanese Military Aircraft Designation Systems
The Japanese military aircraft designation systems for the Imperial period (pre-1945) had multiple designation systems for each armed service. This led to the Allies' use of code names during World War II, and these code names are still better known in English-language texts than the real Japanese names for the aircraft. A number of different schemes were simultaneously in use. Imperial Japanese Navy Air Service The used several different aircraft designation systems simultaneously. Between 1931 and 1945, aircraft had ''Shi'' numbers designating the specification they were designed to. They also had a long form of Type and Model Number system used between 1920 and 1943, a short designation system akin to that of the United States Navy in use between the late 1920s and 1945, a system of popular names introduced to replace type numbers from 1943 through 1945. Specification ''Shi'' numbers Japanese Navy specifications from 1931 were given an experimental, or ''Shi'' (試) number ... [...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 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 o ...

Flying Boats
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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1930s Japanese Patrol Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.

List Of Seaplanes And Flying Boats
The following is a list of seaplanes, which includes floatplanes and flying boats. A seaplane is any airplane that has the capability of landing and taking off from water, while an amphibian is a seaplane which can also operate from land. (They do not include rotorcraft, or ground-effect vehicles which can only skim along close to the water) A flying boat relies on its main hull for buoyancy, while a floatplane has a conventional aircraft fuselage fitted with external floats. In some locales, the term "seaplane" is used as a synonym for floatplane. List A small number of seaplanes have retractable beaching gear, which is not capable of being used for landings and takeoffs, but these remain flying boats or floatplanes and are not amphibians. Many floatplanes, especially those since 1945, can have either conventional floats for operating just from water, or amphibious floats, which have retractable undercarriage built into them. Some experimental flying boats have used skis or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Military Aircraft Of Japan
This list of military aircraft of Japan includes project, prototype, pre-production and operational types regardless of era. This includes both domestically developed Japanese designs, licensed variants of foreign designs, and foreign-produced aircraft that served in the military of Japan. Japanese names are used here, not World War II Allied codenames. The prefix "Ki" in this list is an abbreviation of "Kitai", meaning "airframe", and was used only by the Imperial Japanese Army Air Force. "Ki" should be read as one word.

Hall PH
The Hall PH was an American flying boat of the 1930s. It was a twin-engined biplane, developed from the Naval Aircraft Factory PN and could hence trace its lineage back to the Felixstowe flying boats of World War I. The PH was purchased in small numbers by the United States Navy and the United States Coast Guard. It remained in service with the Coast Guard until 1944, being used for anti-submarine and search and rescue duties. Development and design In December 1927, the U.S. Navy placed a contract with the Hall Aluminum Aircraft Corporation of Bristol, Pennsylvania for a developed version of the Naval Aircraft Factory PN-11,Swanborough and Bowers 1976, p. 254 which itself could trace a development history back to the Felixstowe F.5 flying boat of World War I.Donald 1995, p. 186 The resultant prototype, the XPH-1, first flew in December 1929.Green 1962, p. 175 The XPH-1 had identical wings and a similar metal hull to that of the PN-11, but was fitted with a large single fin and ...

Supermarine Scapa
The Supermarine Scapa was a British general reconnaissance flying boat built by Supermarine that was used by the Royal Air Force between 1935 and 1939. It was developed from the Southampton and formed the basis of the later Stranraer flying boat. Development After experimenting with a three-engine design of flying boat, (the Nanok/Solent/Southampton X), Supermarine's chief designer, R.J. Mitchell, decided that the good hydrodynamic design that had been developed in the twin-engined Southampton, would be the platform for the next aircraft. A prototype designated the Southampton IV was built. It had a hull that performed even better in the tank tests. An Air Ministry Specification was received in November 1931. The test pilot Joseph "Mutt" Summers took the first flight on 8 July 1932. The name had then been changed to the Scapa. 15 Scapas were built before production was changed to a more powerful development, the Stranraer. Design The Scapa hull was an all-metal structure, wh ...

Naval Aircraft Factory PN
The Naval Aircraft Factory PN was a series of open cockpit American flying boats of the 1920s and 1930s. A development of the Felixstowe F5L flying boat of the First World War, variants of the PN were built for the United States Navy by Douglas, Keystone and Martin. Development and design The PN flying boats were twin-engine biplanes with their engines mounted in nacelles between the fabric-covered wings. Other than on the PN-11 which had a different hull form, the hull had large chines running back to the first step similar to those on the F.5L. It had a standard crew of five, but was capable of carrying a relief crew for long patrols. Early machines had wood hulls and wings, with the wings covered in fabric, while various versions replaced these with metal components. A wide variety of V-12 and radial engines were fitted, due to problems with several of the engines chosen, with later versions generally using radial engines.
