Flat-twin
A flat-twin engine is a two-cylinder internal combustion engine with the cylinders on opposite sides of the crankshaft. The most common type of flat-twin engine is the boxer-twin engine, where both pistons move inwards and outwards at the same time. The flat-twin design was patented by Karl Benz in 1896 and the first production flat-twin engine was used in the ''Lanchester 8 hp Phaeton'' car released in 1900. The flat-twin engine was used in several other cars since, however a more common usage is in motorcycles; early models oriented the cylinders in line with the frame, however later models switched to the cylinders being perpendicular to the frame to provide even cooling across both cylinders. Flat-twin engines were also used in several aircraft up until the 1930s and in various stationary applications from the 1930s to the 1960s. The Australian lawnmower manufacturer Victa also produced a flat-twin engine push mower from August 1975 to 1980 dubbed as the ‘Twin 500’ and � ...

JDM Roitelet
__NOTOC__ The JDM Roitelet (French: "Wren") was a single-seat light aircraft marketed in France by Avions JDM shortly after World War II. However, only a single example (the prototype, registration ''F-WFAC'') is known to have been built. It was a low-wing, open cockpit monoplane with tailskid undercarriage. Specifications Avions JDM Avions JDM (from "Jean Dabos et Masclet") was a French aircraft manufacturer established in Neuilly-sur-Seine Neuilly-sur-Seine (; literally 'Neuilly on Seine'), also known simply as Neuilly, is a commune in the department of Hauts-de-Seine in France, just west of Paris.

Ignition Magneto
An ignition magneto, or high-tension magneto, is a magneto that provides current for the ignition system of a spark-ignition engine, such as a petrol engine. It produces pulses of high voltage for the spark plugs. The older term ''tension'' means ''voltage''. The use of ignition magnetos is now confined mainly to engines where there is no other available electrical supply, for example in lawnmowers and chainsaws. It is also widely used in aviation piston engines even though an electrical supply is usually available. In this case, the magneto's self-powered operation is considered to offer increased reliability; in theory, the magneto should continue operation as long as the engine is turning. History Firing the gap of a spark plug, particularly in the combustion chamber of a high-compression engine, requires a greater voltage (or ''higher tension'') than can be achieved by a simple magneto. The ''high-tension magneto'' combines an alternating current magneto generator an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Avia 50-MP
The Avia 50-MP was a French motor glider based on that of the Avia XV-A training glider. First flown in 1934, it was intended to introduce pilots to motor-gliders. Design and development In 1933 Avia introduced two designs based on their earlier training gliders but fitted with low powered engines, placing them amongst the first motor gliders. The Avia 50-MP (MP for moteur planeur or motor glider) was the more basic of the two and was a development of the Avia XV-A. The Avia 50-MP was a monoplane with a two piece high wing of rectangular plan, with blunted tips and about 4.5° of sweep. Broad chord ailerons filled about half the span. The roots were attached to a streamlined, fuselage mounted pillar, and each wing was braced from about half span to the lower fuselage with a pair of parallel struts. The pillar also mounted the pusher configuration Poinsard flat twin engine, its cylinders exposed for air-cooling and driving a two bladed propeller just behind the wing trai ...

SFCA Taupin
The SFCA Taupin was a French tandem-wing aircraft, designed to provide a simple, stable and safe aircraft able to take-off and land in small spaces. Design and development In 1907 Louis Peyret, a friend of Louis Blériot designed the tandem wing Bleriot VI. Alex Manerol, flying the Peyret Tandem won the 1922 Itford glider contest and in 1924 Peyret obtained a patent for it. He continued to build designs of this type as well as more conventional aircraft until his death in 1933, after which his patent rights were purchased by the '' Société Française de Construction Aéronautique'' (SFCA). In 1935 they designed and built the tandem wing Taupin which, apart from a different engine, was very similar to the Peyret VI of 1933. Taupin is the French vernacular name for beetles of the family Elateridae or click-beetles, known for their ability to jump rapidly into the air. The Taupin had rectangular plan wings, the forward one providing 65% of the wing area, both mounted on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piel CP-10 Pinocchio
The Piel CP-10 was a post-war French sports aircraft in the Pou du Ciel tradition and was the first design from Claude Piel to fly. Design and development The CP-10 Pinocchio was the first of Claude Piel's long line of light aircraft designs. Despite the common name, it was completely different to his second design, the CP-20 Pinocchio. Built by Piel and Roger Holleville, the CP-10 was a Pou du Ciel style, single seat tandem-wing aircraft, powered by a Mengin B flat-twin engine mounted in the nose with its cylinder heads exposed for cooling and driving a two bladed propeller. The larger, forward wing was mounted above the flat sided fuselage on each side by two pairs of short, inverted-V struts from the fuselage to the wing rotation axis. The angle of incidence was controlled from the open cockpit by long rods from the lower fuselage to the wing underside near the trailing edge. The shorter span rear wing was mounted on top of the fuselage immediately behind the cockpit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nippi NH-1 Hibari
The Mignet HM.14 ''Flying Flea'' (''Pou du Ciel'' literally "Louse of the Sky" in French) is a single-seat light aircraft first flown in 1933, designed for amateur construction. It was the first of a family of aircraft collectively known as Flying Fleas. Development The HM.14 was designed by French radio engineer Henri Mignet. It was the result of his ambition to design a safe aeroplane that could be built quickly and cheaply by any amateur familiar with simple woodwork and metalwork skills. It followed a progressive series of designs, of which the HM.8 monoplane was already successful as an amateur-built aircraft. On 10 September 1933, at the Bois de Bouleaux near Soissons, Mignet piloted the first flight of the HM.14. In the following months, he made many flights with progressive modifications to improve its handling and performance, totalling 10 hours test-flying time. He described the HM.14 as his Pou no.4, presumably counting from the HM.11, that featured a large pivoting fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mignet HM
Henri Mignet, (October 19, 1893 – August 31, 1965), was a French radio engineer who became well known as an aircraft designer and builder.Ellis & Jones (1990)Plane and Pilot: ''1978 Aircraft Directory'', page 142. Werner & Werner Corp, Santa Monica CA, 1977. His most famous design is the '' Flying Flea'' family of aircraft. Early interest in aviation Mignet was born in Charente-Maritime. In 1911, when he was 18 years old, he started corresponding with Gustav Lilienthal (the brother of Otto Lilienthal) about aviation. In 1912, he built his first aircraft, the HM.1-1 model. It was a monoplane inspired by the creations of Otto Lilienthal. Service in the First World War Between 1914 and 1918, Mignet served in the French army. He was a radio operator during World War I. In 1918, he was hospitalized with malaria. Post World War I designs In 1920, Mignet finished his first powered aircraft prototype, the HM.2. This bore many similarities to, and took inspiration from, the desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jodel D
Société Avions Jodel is a French aircraft company started in 1946 by Édouard Joly and his son-in-law Jean Délémontez. History Jodel designed a range of light aeroplanes shortly after the Second World War. The popular myth is that the two industrialists, with no formal aerodynamics training, set about designing a single-seat aircraft with some spare plywood and a small engine, a Poinsard 25hp 2-cyl. The result was the 1948 D9 Bébé (Baby) model. In fact, the two had much experience of building and designing aircraft, Delemontez being a trained aeronautical engineer, and Joly having built an aircraft before the war. The French government bought many of the aircraft, with more than 500 D9s being built during the next twenty years. Subsequently, the government expressed interest in a larger aircraft as a trainer and the two-seat D11 model followed in 1950. Jodel aircraft are all-wood, usually made from Sitka spruce and plywood made out of okoume (also known as gaboo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 i ...
