SIAI S.67
The SIAI S.67 or Savoia Marchetti SM.67 was an Italian flying boat fighter of the early 1930s designed and manufactured by SIAI. Design and development In 1929, the ''Regia Marina'' (Italian Royal Navy) awarded a contract to SIAI to produce the prototype of a new flying boat fighter for use as a catapult-launched aircraft aboard ''Condottieri''-class cruisers. In response, SIAI designed the S.67, a wooden, single-seat, monoplane flying boat powered by a 313-kilowatt (420-horsepower) Fiat A.20 V12 liquid-cooled engine driving a three-bladed pusher propeller. The wing spars were attached to the fuselage, and the engine was mounted on steel tube struts above the hull, each attached to the engine mount by one pin. The S.67s armament consisted of two fixed, forward-firing 7.7-millimeter (0.303-inch) Vickers machine guns mounted in the bow. The S.67s design allowed a team of six men aboard a cruiser to erect it on its catapult and have it ready for launch within five minutes. Opera ...

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] |
Wing
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift. Lifting structures used in water include various foils, such as hydrofoils. Hydrodynamics is the governing science, rather than aerodynamics. Applications of underwater foils occur in hydroplanes, sailboats and submarines. Etymology and usage For many centuries, the word "wing", from the Old Norse ''vængr'', referred mainly to the foremost limbs of birds (in addition to the architectural aisle). But in recent centuries the word's meaning has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1930s Italian Fighter 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.

Savoia-Marchetti Aircraft
SIAI-Marchetti was an Italian aircraft manufacturer primarily active during the interwar period. History The original company was founded during 1915 as SIAI (''Società Idrovolanti Alta Italia'' - Seaplane Company of Upper Italy). As suggested by its name, the firm initially specialised in the manufacture of seaplanes, the vast majority of which were intended for the Italian armed forces. Perhaps its most prominent early aircraft was the SIAI S.16, a seaplane that had been configured to perform both aerial reconnaissance and bomber roles, but also proved itself quite capable of long-distance flights. During 1925, Italian aviator Francesco de Pinedo of the ''Regia Aeronautica'' (Italian Royal Air Force) used an SIAI S.16''ter'' he named ''Genariello'' for a record-setting flight from Rome to Australia and Tokyo to demonstrate his idea that seaplanes were superior to landplanes for long-distance flights. Having departed Rome on 21 April, Pinedo and his mechanic, Ernesto Campanell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought battleship. With the advent of the dreadnought battleship before World W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow (ship)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ...

Vickers Machine Gun
The Vickers machine gun or Vickers gun is a Water cooling, water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The gun was operated by a three-man crew but typically required more men to move and operate it: one fired, one fed the ammunition, the others helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allies of World War I, Allied World War I fighter aircraft. The weapon had a reputation for great solidity and reliability. Ian V. Hogg, in ''Weapons & War Machines'', describes an action that took place in August 1916, during which the British 100th Company of the Machine Gun Corps fired their ten Vickers guns to deliver sustained fire for twelve hours. Using 100 barrels, they fired a million rounds without breakdowns. "It was this absolute foolproof reliability which endeared the Vickers to every Britis ...

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye.
