Stearman XOSS
The Stearman XOSS was an American biplane observation floatplane developed by Stearman Aircraft for the United States Navy during the late 1930s. Intended to replace the Curtiss SOC Seagull in service aboard battleships, it proved inferior to the Vought OS2U Kingfisher in a fly-off, and did not enter production. Design and development Known by the company designation Model X-85,Phillips 2006, p.148. the Stearman XOSS-1 was designed during 1937 in response to a U.S. Navy specification calling for an observation-scout type aircraft, capable of operating from either water or land, and stressed for catapult launching from battleships and cruisers.Adcock 1991, p.4. The new aircraft was intended to replace the Curtiss SOC as the standard observation and gunnery spotting aircraft in service aboard the Navy's battleships. In response to the request for proposals, the Navy received designs from Stearman Aircraft, Chance Vought, and the Naval Aircraft Factory. The Stearman Model 85, g ...

Pratt & Whitney R-1340
The Pratt & Whitney R-1340 Wasp is an aircraft engine of the reciprocating type that was widely used in American aircraft from the 1920s onward. It was the Pratt & Whitney aircraft company's first engine, and the first of the famed Wasp series. It was a single-row, nine-cylinder, air-cooled, radial design, and displaced 1,344 cubic inches (22 L); bore and stroke were both 5.75 in (146 mm). A total of 34,966 engines were produced. As well as numerous types of fixed-wing aircraft, it was used to power helicopters, the Agusta-Bell AB.102 and the Sikorsky H-19, and a class of airship, the K-class blimp. In 2016, it received designation as a Historic Engineering Landmark from the American Society of Mechanical Engineers.

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 ...

1930s United States Military Reconnaissance 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.

Stearman Aircraft
Stearman Aircraft Corporation was an Aerospace manufacturer, aircraft manufacturer in Wichita, Kansas. Although the company designed a range of other aircraft, it is most known for producing the Boeing-Stearman Model 75, Model 75, which is commonly known simply as the "Stearman" or "Boeing Stearman". History Lloyd Stearman established the Stearman Aircraft Corporation in 1927 in aviation, 1927. Initially, the company was founded as Stearman Aircraft Corporation in October 1926 at Venice, California, where four C1 and C2 biplanes were built before production halted for financial reasons. On 27 September 1927, a new Stearman Aircraft Corporation was founded. The factory was then established in Wichita, Kansas, with financing of Walter Innes, where the new model Stearman C3 and Stearman 4 Speedmail were constructed. Two years later, he sold it to the United Aircraft and Transport Corporation. The Northrop Aircraft Corporation was merged into Stearman in July 1931. In September 1 ...

List Of Flying Boats And Floatplanes
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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IMAM Ro
Imam (; ar, إمام '; plural: ') is an Islamic leadership position. For Sunni Muslims, Imam is most commonly used as the title of a worship leader of a mosque. In this context, imams may lead Islamic worship services, lead prayers, serve as community leaders, and provide religious guidance. Thus for Sunnis, anyone can study the basic Islamic sciences and become an Imam. For most Shia Muslims, the Imams are absolute infallible leaders of the Islamic community after the Prophet. Shias consider the term to be only applicable to the members and descendents of the ''Ahl al-Bayt'', the family of the Islamic prophet Muhammad. In Twelver Shiasm there are 14 infallibles, 12 of which are Imams, the final being Imam Mahdi who will return at the end of times. The title was also used by the Zaidi Shia Imams of Yemen, who eventually founded the Mutawakkilite Kingdom of Yemen (1918–1970). Sunni imams Sunni Islam does not have imams in the same sense as the Shi'a, an important disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitsubishi F1M
The Mitsubishi F1M ( Allied reporting name "Pete") was a Japanese reconnaissance floatplane of World War II. It was the last biplane type of the Imperial Japanese Navy, with 944 built between 1936 and 1944. The Navy designation was "Type Zero Observation Seaplane" (零式水上観測機). Design and development In 1934, the Imperial Japanese Navy issued a specification to Mitsubishi, Aichi and Kawanishi for a replacement for its Nakajima E8N floatplanes, which were used for short-ranged reconnaissance and observation missions from the Navy's warships.Francillon 1970, p. 358. Mitsubishi's design, the Ka-17, given the short system designation F1M1 by the Japanese Navy, was a small all-metal biplane powered by a single Nakajima Hikari 1 radial engine rated at , the same engine as used by Aichi's competing F1A. It had elliptical wings and great care had been taken to reduce drag, with the number of interplane struts and bracing wires minimised. The first of four F1M1s flew in June 1 ...

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...
