Piaggio P.VII
The Piaggio Stella P.VII was the first P series aircraft engine produced by Piaggio Aerospace, Rinaldo Piaggio S.p.A. Based on its experience license-producing the Gnome-Rhône 7K, Piaggio sold the engine to be used on a wide range of Italian aircraft before and during World War II, including the record-breaking Caproni Ca.133. Development Having built engines under licence from Gnome et Rhône, Piaggio designed a seven-cylinder radial using the same principles. The engine, named P.VII for its seven cylinders, was one in a series of radial engines produced by Piaggio initially named ''Stella'', meaning star. The engine was first run in 1933 and was produced in many models. One notable version was the P.VII Z which was fitted with a floatless Piaggio AS80 carburettor for aerobatic flight. It powered the Caproni Ca.133 flown by Renato Donati that, in 1933, broke the record for the longest duration in inverted flight. Variants ;P.VII C.15: Supercharged, rated at at ; first flew 193 ...

Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, 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 ar ...

Bristol Neptune
The Bristol Neptune was a seven-cylinder air-cooled radial engine developed in 1930. It had the same size cylinders as the earlier Mercury and Titan engines, 5.75 in (146 mm) x 6.5 in (165 mm) which gave a displacement of 1,182 cu in (19.3 L) and produced a maximum of 320 horsepower (239 kW). The Neptune was effectively a seven-cylinder version of the Titan.Lumsden 2003, p.103.

Avia Rk
AVIA () is a Soviet/Russian experimental pop band formed in Leningrad in 1986. AVIA released four studio albums and led the first wave of the Soviet bands which made their breakthrough in the West in the late 1980s. Band history AVIA was formed in September 1985 by the ex-members of Strannye Igry, multi-instrumentalists Nikolai Gusev, Alexey Rakhov and drummer Alexander Kondrashkin who were joined by Anton Adasinsky (guitars, vocals), saxophonists Elena Bobretsova and Alexey Merkushev, and performance artist Marat Timergazov who, supported by the ever growing cast of dancers and gymnasts created a peculiar mass pantomime comprising elements of 1920s constructivism, sports parades and the early Soviet visual culture clichés. Equally eclectic was the band's style, a mix of new wave rock, quasi-classical marches and synthpop. In 1987 AVIA received the special Press Award at the Rock Panorama musical festival and featured in Alexey Uchitel's film "Rock". The group's first album, ...

Armstrong Siddeley Cheetah
The Armstrong Siddeley Cheetah is a seven-cylinder British air-cooled aircraft radial engine of 834 cu in (13.65 L) Engine displacement, capacity introduced in 1935 and produced until 1948. Early variants of the Cheetah were initially known as the Lynx Major.Lumsden 2003, p.74. The Cheetah was used to power many British Trainer (aircraft), trainer aircraft during World War II including the Avro Anson and Airspeed Oxford. Design and development The Cheetah was developed from the earlier Lynx using the increased Bore (engine), bore cylinders from the Armstrong Siddeley Panther but the engine retained the Stroke (engine), stroke of the Lynx. Initially only direct-drive variants were produced with later engines being made available with propeller reduction gear of various Gear ratio, ratios. Superchargers were also available for later variants, both geared and directly driven by the crankshaft. The basic design of the Cheetah remained unchanged from its introduction in 1935 to th ...

Gasoline
Gasoline ( North American English) or petrol ( Commonwealth English) is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. When formulated as a fuel for engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries. The ability of a particular gasoline blend to resist premature ignition (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Tetraethyl lead was once widely used to increase the octane rating but is not used in modern automotive gasoline due to the health hazard. Aviation, off-road motor vehicles, and racing car engines still use leaded gasolines. Other substances are frequently added to gasoline to improve chemical st ...

Octane Rating
An octane rating, or octane number, is a standard measure of a liquid fuel, fuel's ability to withstand Compression ratio, compression in an internal combustion engine without causing engine knocking. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates the resistance to detonating under pressure without a spark. Whether a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression Petrol engine, gasoline engines, which may yield higher power for these engines. The added power in such cases comes from the way the engine is designed to compress the air/fuel mixture, and not directly from the rating of the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are idea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrifugal Compressor
Centrifugal compressors, sometimes called impeller compressors or radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. They achieve pressure rise by adding energy to the continuous flow of fluid through the rotor/impeller. The equation in the next section shows this specific energy input. A substantial portion of this energy is kinetic which is converted to increased potential energy/static pressure by slowing the flow through a diffuser. The static pressure rise in the impeller may roughly equal the rise in the diffuser. Components of a simple centrifugal compressor A simple centrifugal compressor stage has four components (listed in order of throughflow): inlet, impeller/rotor, diffuser, and collector. Figure 1.1 shows each of the components of the flow path, with the flow (working gas) entering the centrifugal impeller axially from left to right. This turboshaft (or turboprop) impeller is rotating counter-clockwise when looking downs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
