ENAER Ñamcú
The ENAER ECH-02 Ñamcú was a single-engine, two-seat, light aircraft, designed and built by the Chilean manufacturer ENAER. A first prototype flew in 1989, and while the joint venture company Euro-ENAER was set up to build the aircraft in the Netherlands as the Euro-Enaer Eaglet, these plans failed when Euro-ENAER went bankrupt in 2002. Design and development The Chilean Air Force established an aircraft manufacturing arm, IndAer, in 1980, which began by assembling Piper PA-28 Dakotas and building the ENAER T-35 Pillán military light trainer, which was developed by Piper for manufacture in Chile. IndAer became ENAER (Empresa Nacional de Aeronáutica de Chile), a separate state-owned company, in 1984. In 1986, ENAER began work on its first entirely indigenous aircraft, a two-seat, single-engined light aircraft suitable for use by flying clubs as a training aircraft. As such, the project (at first known as the ''Avion Livano'' (light aircraft)), was to be inexpensive, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft

Polyurethane
Polyurethane (; often abbreviated PUR and PU) refers to a class of polymers composed of organic chemistry, organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many List of polyurethane applications, different applications. These include rigid and flexible foams, varnishes and coatings, adhesives, Potting (electronics), electrical potting compounds, and fibers such as spandex and Polyurethane laminate, PUL. Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting an isocyanate with a polyol. Since a polyurethane contains two types of monomers, which polymerize one after the other, they are classed as Copolymer#Alternating copolymers, alternating copolymers. Both the isocy ...

ENAER Aircraft
ENAER () (''Empresa Nacional de Aeronáutica de Chile'', "National Aeronautical Company of Chile") is a Chilean aircraft manufacturer. History The origins of ENAER can be traced back to 1930, when the Chilean Air Force formed a dedicated maintenance wing, the ''Maestranza Central de Aviación'' (Central Aviation Workshop). During 1980, the Chilean Air Force established an aircraft manufacturing arm, ''IndAer''. During the early 1980s, an agreement with Piper Aircraft saw IndAer begin the local assembly of the firm's PA-28 Dakotas for the Chilean Air Force. Around the same period, it also started building the ENAER T-35 Pillán, a military light trainer, which was developed for manufacture in Chile by Piper, based on a PA-32R fuselage with a new center-section and wing stressed for aerobatics. The first production aircraft was delivered by ENAER to the Chilean Air Force Air Academy in August 1985. On 16 March 1984, IndAer was reorganised as a state-owned company separate to the ...

Joint Aviation Authorities
The Joint Aviation Authorities (JAA) was an associated body of the European Civil Aviation Conference representing the civil aviation regulatory authorities of a number of European States who had agreed to co-operate in developing and implementing common safety regulatory standards and procedures. It was not a regulatory body, regulation being achieved through the member authorities. It was in existence from 1970 until disbanded in 2009. Its headquarters were located in Hoofddorp near Schiphol airport in Netherlands. JAA issued the Joint Aviation Requirements (JAR), intended to establish minimum requirements for air safety. In implementing the so-called FUJA Report, the JAA had entered into a new phase as of 1 January 2007. In this new phase the former "JAA" had become "JAA T" (Transition). JAA T consisted of a Liaison Office (JAA LO) and a Training Office (JAA TO). The offices of JAA LO were located in the premises of European Aviation Safety Agency (E ...

Lycoming O-320
The Lycoming O-320 is a large family of naturally aspirated, air-cooled, four-cylinder, direct-drive engines produced by Lycoming Engines. They are commonly used on light aircraft such as the Cessna 172 and Piper Cherokee. Different variants are rated for 150 or 160 horsepower (112 or 119 kilowatts). As implied by the engine's name, its cylinders are arranged in horizontally opposed configuration and a displacement of 320 cubic inches (5.24 L). Design and development The O-320 family of engines includes the carbureted O-320, the fuel-injected IO-320, the inverted mount, fuel-injected AIO-320 and the aerobatic, fuel-injected AEIO-320 series. The LIO-320 is a "left-handed" version with the crankshaft rotating in the opposite direction for use on twin-engined aircraft to eliminate the critical engine. The first O-320 (with no suffix) was FAA certified on 28 July 1953 to CAR 13 effective 5 March 1952; this same engine was later re-designated, without change, as the O-320-A1 ...

Type Certificate
A type certificate signifies the airworthiness of a particular category of aircraft, according to its manufacturing design (''type design''). It confirms that the aircraft of a new type intended for serial production, is in compliance with applicable airworthiness requirements established by the national air law. For up to three seats, primary category aircraft, certification costs around US$1m, US$25m for a general aviation aircraft and hundreds of millions of dollars for a commercial aircraft; certification delays can cost millions of dollars and can decide a program's profitability. Authority A type certificate (TC) is issued to signify the airworthiness of the approved design or "type" of an aircraft to be manufactured. The TC is issued by a regulatory authority, and once issued, the design cannot be changed unless at least part of the process for certification is repeated to cover the changes. The TC reflects a determination made by a regulatory authority that the type desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bird Strike
A bird strike—sometimes called birdstrike, bird ingestion (for an engine), bird hit, or bird aircraft strike hazard (BASH)—is a collision between an airborne animal (usually a bird or bat) and a moving vehicle, usually an aircraft. The term is also used for bird deaths resulting from collisions with structures such as power lines, towers and wind turbines (see Bird–skyscraper collisions and Towerkill). A significant threat to flight safety, bird strikes have caused a number of accidents with human casualties. There are over 13,000 bird strikes annually in the US alone. However, the number of major accidents involving civil aircraft is quite low and it has been estimated that there is only about 1 accident resulting in human death in one billion (109) flying hours. The majority of bird strikes (65%) cause little damage to the aircraft; however, the collision is usually fatal to the bird(s) involved. The Canada goose has been ranked as the third most hazardous wildlife spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat-four
A flat-four engine, also known as a horizontally opposed-four engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than an inline-four engine. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasionally been used in motorcycles and frequently in aircraft. Cessna and Piper use flat four engines from Lycoming and Continental in the most common civil aircraft in the world - the Cessna 172, and Piper Cherokee, while many ultralight and LSA planes use versions of the Rotax 912. Design Most flat-four engines are designed so that each pair of opposing pistons moves inwards and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gull-wing Door
In the automotive industry, a gull-wing door, also known as a falcon-wing door or an up-door, is a car door that is hinged at the roof rather than the side, as pioneered by Mercedes-Benz 300 SL, first as a race car in 1952 ( W194), and then as a production sports car in 1954. Opening upwards, the doors evoke the image of a seagull's wings. In French, they are (butterfly doors). The papillon door was designed by Jean Bugatti for the 1939 Type 64, 14 years before Mercedes-Benz produced its similar, famous 300 SL gullwing door. The papillon door is a precursor to the gullwing door, and is slightly different in its architecture, but is often overlooked when discussing gull-wing design. Conventional car doors are typically hinged at the front-facing edge of the door, with the door swinging outward horizontally. Apart from the Mercedes-Benz 300 SL of the mid-1950s, Mercedes-Benz SLS and the experimental Mercedes-Benz C111 of the early 1970s, the best-known examples of road-cars w ...
