Aircraft Engines
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

Ramjet Engine
A ramjet, or athodyd (aero thermodynamic duct), is a form of airbreathing jet engine that uses the forward motion of the engine to produce thrust. Since it produces no thrust when stationary (no ram air) ramjet-powered vehicles require an assisted take-off like a rocket assist to accelerate it to a speed where it begins to produce thrust. Ramjets work most efficiently at supersonic speeds around and can operate up to speeds of . Ramjets can be particularly useful in applications requiring a small and simple mechanism for high-speed use, such as missiles. The US, Canada, and UK had widespread ramjet powered missile defenses during the 1960s onward, such as the CIM-10 Bomarc and Bloodhound. Weapon designers are looking to use ramjet technology in artillery shells to give added range; a 120 mm mortar shell, if assisted by a ramjet, is thought to be able to attain a range of . They have also been used successfully, though not efficiently, as tip jets on the ends of helicopt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
René Lorin
René Lorin (24 March 1877 – 16 January 1933) was a French aerospace engineer and inventor of the ramjet. In 1908 Lorin patented the first subsonic ramjet design. He published the principles of a ramjet in articles in the journal ''L'Aérophile'' from 1908 to 1913, expressing the idea that the exhaust from internal combustion engines could be directed into nozzles to create jet propulsion. He could not test this invention since there was no way at the time for an aircraft to go fast enough for a ramjet to function properly. When René Leduc applied for a patent on a ramjet design in 1933, he discovered Lorin's publications and tried to contact him, only to learn that he had recently died. Leduc thereafter paid homage to Lorin's work. René Lorin is a graduate of the École Centrale Paris École Centrale Paris (ECP; also known as École Centrale or Centrale) was a French grande école in engineering and science. It was also known by its official name ''École Centrale des Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V8 Engine
A V8 engine is an eight-cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. The first V8 engine was produced by the French Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient, lower capacity engines, or hybrid and electric drivetrains. Design V-angle The majority of V8 engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations; however, the downside is a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Léon Levavasseur
Léon Levavasseur (8 January 1863 – 26 February 1922) was a French powerplant engineer, aircraft designer and inventor. His innovations included the V8 engine, direct fuel injection, and liquid engine cooling. Primarily associated with the Antoinette company, he continued to experiment with aircraft design after the company went bankrupt. Early life Levavasseur was born in Le Mesnil-au-Val, Cherbourg, France to a naval officer. Initially studying fine arts, Levavasseur switched to studying engineering, with a particular interest in arc lamps and petrol engines. The Antoinette company The engine enterprise and incorporation In the summer of 1902, Levavasseur suggested to industrialist Jules Gastambide that powerful, lightweight engines would be necessary for powered flight, and proposed the manufacture of these engines. He also proposed that the engines be named after Gastambide's daughter, Antoinette. Gastambide financed the venture. Levavasseur patented the V8 ...

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized 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 around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

Wright Flyer
The ''Wright Flyer'' (also known as the ''Kitty Hawk'', ''Flyer'' I or the 1903 ''Flyer'') made the first sustained flight by a manned heavier-than-air powered and controlled aircraft—an airplane—on December 17, 1903. Invented and flown by Orville and Wilbur Wright, it marked the beginning of the pioneer era of aviation. The Wright brothers flew the ''Wright Flyer'' four times that day on land now part of the town of Kill Devil Hills, about south of Kitty Hawk, North Carolina. The aircraft was preserved and is now exhibited in the National Air and Space Museum in Washington, D.C. Design and construction The ''Flyer'' was based on the Wrights' experience testing gliders at Kitty Hawk between 1900 and 1902. Their last glider, the 1902 Glider, led directly to the design of the ''Wright Flyer''. The Wrights built the aircraft in 1903 using spruce for straight members of the airframe (such as wing spars) and ash wood for curved components (wing ribs). The wings were desi ...

Inline Engine (aviation)
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° betwe ...

Charlie Taylor (mechanic)
Charles Edward Taylor (May 24, 1868 – January 30, 1956) was an American inventor, mechanic and machinist. He built the first aircraft engine used by the Wright brothers in the ''Wright Flyer'', and was a vital contributor of mechanical skills in the building and maintaining of early Wright engines and airplanes. Biography He was born in a log cabin on May 24, 1868, in Cerro Gordo, Illinois, to William Stephen Taylor and Mary Jane Germain. Taylor worked as a binder at the ''Nebraska State Journal'' at age 12. He became a tool maker. At 24, he met and married Henrietta Webbert, who was from Dayton, Ohio. They had a child and moved to Dayton, where prospects were better. Stoddard Manufacturing Co. hired him to make farm machinery and bicycles. But when the Wright brothers began renting from his wife's uncle a building for their bicycle shop, he went to work for them. Initially, Taylor was hired to fix bicycles, but increasingly took over running of the bicycle business as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Stringfellow
John Stringfellow (1799 – 13 December 1883) was a British early aeronautical inventor, known for his work on the aerial steam carriage with William Samuel Henson. Life Stringfellow was born in Attercliffe, England to Martha ée Gillanand William Stringfellow, stone mason. Initially apprenticed to the lace making trade in Nottingham, c.1820 he relocated to Chard, Somerset to work as an engineer of bobbins and carriages for the lace industry, becoming so successful that he started his own company. On 27 February 1827 he married Hannah Keetch. They had 10 children, including a son who died in infancy and a daughter, Laura, with epilepsy who died age 29. Together with William Samuel Henson, he had ambitions of creating an international company, the Aerial Transit Company, with designs showing aeroplane travel to exotic locations like Egypt and China. The initial designs were flawed, with Stringfellow's ideas centred on monoplane and triplane models and Henson's ideas ce ...
