ACBA Midour
__NOTOC__ The ACBA Midour, Midour 2 and Midour 3 are a series of glider tugs manufactured by the Aéro Club du Bas Armagnac in France, and named after the Midou River. Design and development The Midour is a double-seat, low-wing monoplane of conventional configuration, fitted with a fixed, tricycle undercarriage. Developed in the workshop of the ACBA using the wings of a Robin DR400, the Midour first flew in the early 1970s and four additional examples to the original design have been built, along with two modified versions. Although the Midour is sometimes equipped with only a single seat, a passenger can be carried behind the pilot, to assist in the release of gliders being towed. Variants ;ACBA-7 Midour :Original version with Lycoming O-360 engine; five built. ;ACBA-8 Midour 2 :Improved version with entirely new wing design.

Horizontally-opposed
A flat engine is a Internal combustion engine#Reciprocating engines, piston engine where the cylinders are located on either side of a central crankshaft. Flat engines are also known as horizontally opposed engines, however this is distinct from the less common opposed-piston engine design, whereby each cylinder has two pistons sharing a central combustion chamber. The most common configuration of flat engines is the #boxer engine, boxer engine configuration, in which the pistons of each opposed pair of cylinders move inwards and outwards at the same time. The other configuration is effectively a V engine with a 180-degree angle between the cylinder banks; in this configuration each pair of cylinders shares a single crankpin, so that as one piston moves inward, the other moves outward. The first flat engine was built in 1897 by Karl Benz. Flat engines have been used in aviation, motorcycle and automobile applications. They are now less common in cars than straight engines (for ...

Airliners
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PZL-104 Wilga
PZL-104 Wilga (''golden oriole'') is a Polish short-takeoff-and-landing (STOL) civil aviation utility aircraft designed and originally manufactured by PZL Warszawa-Okęcie, and later by European Aeronautic Defence and Space Company (EADS), who had acquired the original manufacturer during 2001. First flown on 24 April 1962 and entering service during the following year, the Wilga has evolved through many ever-improving versions during its continuous production from 1962 to 2006. The type was largely used by civil operators; those military air services that did fly the type typically used it as a trainer and liaison aircraft. In excess of 1,000 aircraft were produced prior to European Aeronautic Defence and Space Company (EADS) announcing on their website that production of the Wilga would cease in 2006. Development Origins The PZL-104 was designed for robust use in sports and civil aviation, with a strong emphasis on glider-towing and parachute training. On 24 April 1962, the p ...

Aero L-60 Brigadýr
The Aero L-60 Brigadýr ( cs, Brigadier) was a small, high-wing propeller-driven Czechoslovakian STOL utility aircraft developed for both civil and military use. A prototype, designated XL-60, with Argus As 10C engine, first flew on December 24, 1953, but it was not successful. The plane was thoroughly redesigned and the second improved prototype, with M-208B flat-six engine, flew on June 8, 1954. The aircraft's configuration bears a strong resemblance to the Fieseler Fi 156 "Storch" licence-produced in Czechoslovakia during and after World War II (as K-65 Čáp), and which this aircraft was intended to replace. By the end of production in 1960, 273 had been built by Aero, including an improved version, the L-160 with an all-metal tail. Aircraft retrofitted with a PZL-built Ivchenko AI-14R radial engine are known as the L-60S. Variants * XL-60 : Prototype. * L-60 : Single-engined light utility transport, observation aircraft. * L-60A : 50 production aircraft for the Czech Air ...

Piston Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intro ...

Noise Pollution
Noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with ranging impacts on the activity of human or animal life, most of them are harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport, and propagation systems.Senate Public Works Committee. ''Noise Pollution and Abatement Act of 1972''. S. Rep. No. 1160, 92nd Congress. 2nd session Poor urban planning may give rise to noise disintegration or pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas. Some of the main sources of noise in residential areas include loud music, transportation (traffic, rail, airplanes, etc.), lawn care maintenance, construction, electrical generators, wind turbines, explosions, and people. Documented problems associated with noise in urban environments go back as far as ancient Rome. Research suggests that noise pollution in the United States is the high ...

Robin DR400
The Robin DR400 is a wooden sport monoplane, conceived by Pierre Robin and Jean Délémontez. The Robin DR400 first flew in 1972 and is still in production. The current model is designated 'DR401'. It has a tricycle undercarriage and can carry four people. The DR400 has a 'cranked wing' configuration, with the dihedral angle of the outer wing much greater than the inboard, a configuration which they share with Jodel aircraft. This model is considered easy to fly by many and quiet during flight due to its wooden frame. Development The Robin DR300 series were developments of the earlier DR.221 Dauphin and DR.250 Capitaine with a tricycle landing gear. The first variant was the DR340 Major, a tricycle landing gear version of the DR250 Capitaine which first flew on 27 February 1968, followed on 21 March 1968 by the DR315 Petit Prince, a tricycle landing gear version of the DR221 Dauphin. The DR315 was later replaced by the DR300. In 1972 an improved version, the DR400 was introduce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycoming O-360
The Lycoming O-360 is a family of four-cylinder, direct-drive, horizontally opposed, air-cooled, piston aircraft engines. Engines in the O-360 series produce between 145 and 225 horsepower (109 to 168 kW), with the basic O-360 producing 180 horsepower. The engine family has been installed in thousands of aircraft, including the Cessna 172, Piper Cherokee/Archer, Grumman Tiger, and many home-built types. It has a factory rated time between overhaul (TBO) of 2000 hours or twelve years. O-360 family engines are also widely used in airboats, most notably in the Hurricane Aircats used by the US Army during the Vietnam War. The first O-360 certified was the A1A model, certified on 20 July 1955 to United States CAR 13 effective March 5, 1952 as amended by 13-1 and 13-2. The Lycoming IO-390 is an O-360 which has had its cylinder bore increased by , developing . Series The O-360 family of engines comprises 167 different models with 12 different prefixes.
