Aircraft Engines
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft Air propulsion, propulsion system. Aircraft using power components are referred to as powered flight. Most aircraft engines are either Reciprocating engine, piston engines or gas turbines, although a few have been Rocket-powered aircraft, rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market. Development history * 1903: Manly-Balzer engine sets standards for later radial engines. * 1910: Coandă-1910, an unsuccessful ducted fan aircraft exhibited at Paris Aero Salon, powered by a piston engine. The aircraft never flew, but a patent was filed for routing exhaust gases into the duct to augment thrust. * 1914: Auguste Rateau suggests using exhaust-powered compressor – a turbocharger – to imp ...

Sanford Alexander Moss
Sanford Alexander Moss (August 23, 1872 – November 10, 1946) was an American aviation engineer, who was the first to use a turbocharger on an aircraft engine. Life and career Sanford Moss was born 1872 in San Francisco, California to Ernest Goodman Moss and Josephine Sanford. He received his B.S. and M.S. in engineering from the University of California, San Francisco. On August 23, 1899, he married Jennie Edith Somerville Donnely in Chicago, Illinois. Moss received his Ph.D. from Cornell University where he built his first gas turbine engine. In 1903 after graduation, Moss became an engineer for General Electric's Steam Turbine Department in Lynn, Massachusetts.Leyes, p.231-232. At GE he worked with Elihu Thomson, Edwin W. Rice, and Charles Steinmetz. While there, he applied some of his concepts in the development of the turbosupercharger. His design used a small turbine wheel, driven by exhaust gases, to turn a supercharger. In autumn of 1917 William F. Durand, Di ...

Rolls-Royce Merlin
The Rolls-Royce Merlin is a British Coolant#Liquids, liquid-cooled V12 engine, V-12 Reciprocating engine, piston aero engine of 27-litre (1,650 cu in) Engine displacement, capacity. Rolls-Royce Limited, Rolls-Royce designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12, it was later called ''Merlin (bird), Merlin'' following the company convention of naming its four-stroke piston aero engines after birds of prey. The engine benefitted from the racing experiences of precursor engines in the 1930s. After several modifications, the first production variants of the PV-12 were completed in 1936. The first operational aircraft to enter service using the Merlin were the Fairey Battle, Hawker Hurricane and Supermarine Spitfire. The Merlin remains most closely associated with the Spitfire and Hurricane, although the majority of the production run was for the four-engined Avro Lancaster heavy bomber. The Merlin continued to benefit from a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ranger L-440
The Ranger L-440 (company designation 6-440C) are six-cylinder inline inverted air-cooled aero-engines produced by the Ranger/Fairchild Engines, Ranger Aircraft Engine Division of the Fairchild Aircraft, Fairchild Engine and Airplane Corporation of Farmingdale, New York, United States. The engine was mainly produced for Fairchild's family of training aircraft in the mid-1930s. According to H.L. Puckett, "Ranger developed a system of air cooling all cylinders to a high degree of uniformity. The system employed air under pressure, admitted through an opening in the front of the engine cowling. The air traveled through the tunnel from the air scoop. The tunnel, with one side fitted with corrugations, directed the air against the cylinders at relatively equal pressure and volume. Baffles between the cylinders directed the air past machined cooling fins around the cylinder barrels and heads. This gave remarkably balanced temperature range in level flight..."

Inline Engine (aeronautics)
In aviation, an inline engine is a reciprocating engine with banks of cylinders, one behind another, rather than rows of cylinders, with each bank having any number of cylinders, although more than six is uncommon. The major reciprocating-engine alternative configuration is the radial engine, where the cylinders are placed in a circular or "star" arrangement. The term "inline" is used somewhat differently for aircraft engines than automotive engines. For automotive engines, the term ‘inline’ refers only to straight engines (those with a single bank of cylinders). But for aircraft, ‘inline’ can also refer to engines which are not of the straight configuration, such as V, H, or horizontally opposed. Inline engine configurations ;Straight: Engines with a single bank of cylinders which can be arranged at any angle but typically upright or inverted, (e.g. upright ADC Cirrus, inverted de Havilland Gipsy Major). ; V:Engines with two banks of cylinders with less than 180° bet ...

H Engine
An H engine is a piston engine comprising two separate flat engine, flat engines (complete with separate crankshafts), most often geared to a common output shaft. The name "H engine" is due to the engine blocks resembling a letter "H" when viewed from the front. The most successful "H" engine in this form was the Napier Dagger and its derivatives. The name was also applied to engines of the same basic layout, but rotated through 90 degrees—most famously the Napier Sabre series. A variation on the "H" theme were the Fairey Prince (H-16) & Fairey Monarch, Fairey P.24 Monarch, where the two engines retained separate drives, driving Contra-rotating propellers through separate concentric shafts. Although successful, they only existed in prototype form. The H engine is a relatively rare layout, with its main use being in aircraft engines during the 1930s and 1940s. The 1966 Lotus 43 Formula One car used a BRM 16-cylinder H engine, and an 8-cylinder H engine was used for powerboat rac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
U Engine
A U engine is a piston engine made up of two separate straight engines (complete with separate crankshafts) placed side-by-side and coupled to a shared output shaft. When viewed from the front, the engine block resembles the letter "U". Although much less common than the similar V engine design, several U engines were produced from 1915 to 1987 for use in airplanes, racing cars, racing and road motorcycles, locomotives, and tanks. Design The main benefit of a U engine layout is the ability to share common parts with a straight engine upon which is it based. Additionally, if the two crankshafts rotate in opposite directions, the gyroscopic effect of the rotating components in each cylinder bank cancel each other out. A V engine is typically more compact and lighter than a U engine, in part due to the lack of a second crankshaft, making V engines far more common than U engines. However, the V engine does not cancel the gyroscopic effect. The H engine layout uses a similar con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X Engine
An X engine is a piston engine with four banks of cylinders around a common crankshaft, such that the cylinders form an "X" shape when viewed front-on. The advantage of an X engine is that it is shorter than a V engine of the same number of cylinders, however the drawbacks are greater weight and complexity as compared to a radial engine. Therefore, the configuration has been rarely used. Several of the X engine designs were based on combining two V engines. Examples Four types of X engines are known to have reached production. In 1939–1942 Rolls-Royce Vulture, a X-24 aircraft engine which was built using two Rolls-Royce Peregrine V12 engines. The Rolls-Royce Vulture was briefly used in the Avro Manchester heavy bomber, before engine failures caused it to be replaced by the Avro Lancaster (powered by the Rolls-Royce Merlin V12 engine). General Motors also produced X engines for US naval ships during the Second World War. The 16-184 engine was installed in several hundred ...

EASA
The European Union Aviation Safety Agency (EASA) is an agency of the European Commission with responsibility for civil aviation safety in the European Union. It carries out certification, regulation and standardisation and also performs investigation and monitoring. It collects and analyses safety data, drafts and advises on safety legislation and co-ordinates with similar organisations in other parts of the world. The idea of a European-level aviation safety authority goes back to 1996, but the agency was legally established only in 2002; it began its work in 2003. History Based in Cologne, Germany, the agency was created on 15 July 2002 as the "European Aviation Safety Agency", and reached full functionality in 2008, taking over functions of the Joint Aviation Authorities. It was renamed the "European Union Aviation Safety Agency" in 2018. European Free Trade Association countries participate in the agency. The United Kingdom was a member until the end of the Brexit trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
