Piaggio P.7
The Piaggio P.7, also known as the Piaggio-Pegna P.c.7, was an Italian Air racing, racing seaplane designed and built by Piaggio Aero, Piaggio for the 1929 Schneider Trophy race. Design and development Seeking to avoid the aerodynamic drag induced by floats in seaplanes of floatplane design, Engineer's degree, Ing Giovanni Pegna of the Piaggio Aero, Piaggio company designed a very unusual seaplane to represent Italy in the 1929 Schneider Trophy race. A Cantilever#Aircraft, cantilever shoulder-wing monoplane, known both as the Piaggio P.7 and the Piaggio-Pegna P.c.7, his design floated up to its wings on its long, slender, watertight fuselage with the wings resting on the water, and employed twin high-angle of incidence (aerodynamics), incidence Planing (sailing), hydrofoils to get itself off the water during takeoff runs.Vašiček, Per. ''Aviation History'', September 2002, p. 35. Sources differ on the P.7s engine; it is described both as an Isotta Fraschini Special V6 engine, ...

Isotta Fraschini
Isotta Fraschini () was an Italian luxury car manufacturer, also producing trucks, as well as engines for marine and aviation use. Founded in Milan, Italy, in 1900 by Cesare Isotta and the brothers Vincenzo, Antonio, and Oreste Fraschini, in 1955 it was merged with engine manufacturer Breda Motori and renamed F.A. Isotta Fraschini e Motori Breda. History The firm was named for its founders, Cesare Isotta and Vincenzo Fraschini, who had been importing Mors and Renault automobiles as well as Aster proprietary engines since 1899. The company they founded as Società Milanese Automobili Isotta, Fraschini & C. on 27 January 1900 had the stated purpose to "Import, sell, repair cars". Prior to establishing their own products in 1904, Isotta and Fraschini assembled cars very similar to Renaults, with Aster engines. They differed from the real Renaults in having a neater underslung front radiator arrangement. The first automobile bearing this marque featured a four-cylinder engine wi ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Macchi M
Aermacchi was an Italian aircraft manufacturer. Formerly known as Aeronautica Macchi, the company was founded in 1912 by Giulio Macchi at Varese in north-western Lombardy as Nieuport-Macchi, to build Nieuport monoplanes under licence for the Italian military. With a factory located on the shores of Lake Varese, the firm originally manufactured a series of Nieuport designs, as well as seaplanes. After World War II, the company began producing motorcycles as a way to fill the post-war need for cheap, efficient transportation. The company later specialised in civil and military pilot training aircraft. In July 2003, Aermacchi was integrated into the Finmeccanica Group (now Leonardo) as Alenia Aermacchi, which increased its shareholding to 99%. Military trainers Since the beginning, the design and production of military trainers have been the core business of Alenia Aermacchi. The products include: * SF-260, piston-engined or turboprop-powered screener/primary trai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Garda
Lake Garda ( it, Lago di Garda or ; lmo, label= Eastern Lombard, Lach de Garda; vec, Ƚago de Garda; la, Benacus; grc, Βήνακος) is the largest lake in Italy. It is a popular holiday location in northern Italy, about halfway between Brescia and Verona, and between Venice and Milan on the edge of the Dolomites. Glaciers formed this alpine region at the end of the last ice age. The lake and its shoreline are divided between the provinces of Brescia (to the south-west), Verona (south-east) and Trentino (north). Etymology In Roman times the lake was known as ''Benacus'' and by some it was revered as god Benacus, the personification of the lake, sometimes associated with the cult of Neptune. Today it is better known as Lake Garda, a toponym of Germanic origin attested since the Middle Ages and deriving from that of the homonymous town on the Veronese shore of the lake, which, together with another famous locality of the lake, Gardone Riviera, and others less known – ...

Tommaso Dal Molin
Tommaso Dal Molin (3 January 1902 – 18 January 1930) was an Italian fighter pilot and internationally prominent seaplane air racer and aerobatic pilot of the 1920s. Biography Dal Molin was born on 3 January 1902 in Molino di Altissimo, a hamlet in the ''comune'' of Altissimo, in the Province of Vicenza in Veneto, Italy. A few years later, his family moved to a home on the ''Via'' Bonifacio Biolo in Chiampo. After working at the Pellizzari Works in Arzignano, Dal Molin decided to join the Royal Italian Army′s ''Corpo Aeronautico Militare'' ("Military Aviation Corps") in 1922. He obtained a pilot's license on 13 October 1922. In 1923, the ''Corpo Aeronautico Militare'' became an independent branch of military service as the ''Regia Aeronautica'' (Italian Royal Air Force). Dal Molin demonstrated superior ability and temperament while serving in various ''Regia Aeronautica'' fighter squadrons, both in training and as an aerobatic pilot. As a result, the ''Regia Aeronautica'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blade Pitch
Blade pitch or simply pitch refers to the angle of a blade in a fluid. The term has applications in aeronautics, shipping, and other fields. Aeronautics In aeronautics, blade pitch refers to the angle of the blades of an aircraft propeller or helicopter rotor. Blade pitch is measured relative to the aircraft body. It is usually described as "fine" or "low" for a more vertical blade angle, and ,# "coarse" or "high" for a more horizontal blade angle. * i n Blade pitch is normally described as a ratio of forward distance per rotation assuming no slip. Blade pitch acts much like the gearing of the final drive of a car. Low pitch yields good low speed acceleration (and climb rate in an aircraft) while high pitch optimizes high speed performance and fuel economy. It is quite common for an aircraft to be designed with a variable-pitch * propeller, to give maximum thrust over a larger speed range. A fine pitch would be used during take-off and landing, whereas a coarser pitch i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clutch
A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears. In a torque-controlled drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at th ...

Carburettor
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American Engli ...

Propeller (aircraft)
An aircraft propeller, also called an airscrew,Beaumont, R.A.; ''Aeronautical Engineering'', Odhams, 1942, Chapter 13, "Airscrews". converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type. The propeller attaches to the power source's driveshaft either directly or through reduction gearing. Propellers can be made from wood, metal or composite materials. Propellers are most suitable for use at subsonic airspeeds generally below about , although supersonic speeds were achieved in the McDonnell XF-88B experimental propeller-equipped aircraft. Supersonic tip-speeds are used in some aircraft like the Tupolev Tu-95, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorboat
A motorboat, speedboat or powerboat is a boat that is exclusively powered by an engine. Some motorboats are fitted with inboard motor, inboard engines, others have an outboard motor installed on the rear, containing the internal combustion engine, the gear reduction, gearbox and the propeller in one portable unit. An inboard-outboard contains a hybrid of an inboard and an outboard, where the internal combustion engine is installed inside the boat, and the gearbox and propeller are outside. There are two configurations of an inboard, V-drive and direct drive. A direct drive has the powerplant mounted near the middle of the boat with the propeller shaft straight out the back, where a V-drive has the powerplant mounted in the back of the boat facing backwards having the shaft go towards the front of the boat then making a ''V'' towards the rear. Overview A motorboat has one or more engines that propel the vessel over the top of the water. Boat engines vary in shape, size, ...
