Piston
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder. __TOC__ Piston engines Internal combustion engines An internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts downwards through the connecting rod and onto the crankshaft. The connecting rod is att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Engine
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.

Franklin Engine Company
The Franklin Engine Company was an American manufacturer of aircraft engines. Its designs were used primarily in the civilian market, both in fixed wing and helicopter designs. It was briefly directed towards automobile engines as part of the Tucker Car Corporation, returning to aviation when that company failed. The company was later purchased by the Government of Poland. History The firm began as the H. H. Franklin Co. in 1902 in Syracuse, New York, USA, to produce Franklin air-cooled automobiles. Barely surviving bankruptcy in 1933, the company was purchased by a group of ex-employees and renamed Aircooled Motors in 1937. While the company kept the name of "Aircooled Motors," its engines continued to be marketed under the Franklin name. Engineers Carl Doman and Ed Marks kept the company alive through the depression by manufacturing air-cooled truck and industrial engines. During World War II Aircooled Motors was very successful producing helicopter and airplane engines. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat-six Engine
A flat-six engine, also known as a horizontally opposed-six, is a six-cylinder piston engine with three cylinders on each side of a central crankshaft. The most common type of flat-six engine is the boxer-six engine, where each pair of opposed cylinders moves inwards and outwards at the same time. The advantages of the flat-six layout are good engine balance (for reduced vibration), a low center of gravity, short length (compared with an inline-six engine) and being well suited to air-cooling. The disadvantages are a large width (which can limit the maximum steering angle when used in a front-engined car), a large intake manifold being required when a central carburetor is used, and duplication of the inlet and outlet connections for water-cooled engines. The first production flat-six engine was in the 1904 ''Wilson-Pilcher 18/24 HP'' car. The most notable use of flat-six engines is the Porsche 911 sports car, which has used flat-six engines continuously since 1963. Several o ...

Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of the power an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole engine. The formula is: : \text = \text \times \frac \times ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller Speed Reduction Unit
A propeller speed reduction unit is a gearbox or a belt and pulley device used to reduce the output revolutions per minute (rpm) from the higher input rpm of the powerplant.Gunston 2006, p. 82. This allows the use of small displacement internal combustion engines to turn aircraft propellers within an efficient speed range. History and operation The Wright brothers recognised the need for propeller reduction gearing in 1903, but it was not generally used on aircraft engines until larger engines were designed in the 1920s. Large engines with high crankshaft speeds and power outputs demanded propeller reduction, pilots noted the increase in performance of similar aircraft fitted with reduction gearing. Types Types of propeller speed reduction units include: *Chain drive *Single reduction or spur gear *Internal spur gear *Farman or bevel planetary type *Fixed sun gear *Fixed internal gear *Belt drive *Epicyclic gearing Design variations The Rolls-Royce Falcon engine of 1915 fea ...

Bellanca Cruisair
The Bellanca 14-7 Cruisair and its successors were a family of single-engined light aircraft manufactured in the United States from the mid-1930s onwards.Palmer 2001, p. 51. Design and development Bellanca established itself in the market for 6-8 seat aircraft, but believed that it could also successfully sell smaller 3-4 seat aircraft. To fill this niche Bellanca designed The '14-7 Cruisair' as a modern, low-wing cantilever monoplane with a fuselage intended to contribute lift to the design. Although the prototype flew with fixed tailwheel undercarriage, the 14-9 production version was the first US light aircraft to be mass-produced with retractable undercarriage, the main wheels rotating aft into wheel-wells in the wings, with approximately 50 produced before production was interrupted by World War II. After WWII Bellanca resumed production with the up-dated Bellanca 14-13 Cruisair Senior, retaining the Bellanca 14-7's basic design, featuring an enlarged cabin, a horizont ...

Northrop N-1M
The Northrop N-1M (''Northrop Model 1 Mockup''), also known by the nickname "Jeep", is a retired American experimental aircraft used in the development of the flying wing concept by Northrop Aircraft during the 1940s. Design and development Jack Northrop became involved with all-wing aircraft designs in the late-1920s, with his first flying wing research prototype being built in the 1928–1930 time period. That first prototype, registered X-216H, had evolved from earlier design studies but was not yet a true flying wing as it retained a tail unit comprising twin rudders with a single horizontal stabilizer running between them; both rudders were connected by twin booms to the thick, all-wing blended fuselage. The aircraft had an open cockpit in the center wing section and single, rear-facing, pusher propeller connected to a Menasco Cirrus inverted-four piston engine blended into the all-wing shape. X-216H was first flown in 1929 with Edward Bellande at the controls; the aircra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stinson L-5 Sentinel
The Stinson L-5 Sentinel is a World War II-era liaison aircraft used by the United States Army Air Forces, U.S. Army Ground Forces, U.S. Marine Corps and the British Royal Air Force. It was produced by the Stinson Division of the Vultee Aircraft Company (Consolidated-Vultee from mid-1943). Along with the Stinson L-1 Vigilant, the L-5 was the only other American liaison aircraft that was exclusively built for military use and had no civilian counterpart. Design and development The origins of the L-5 can be traced to the prewar civilian Stinson HW-75. This 75 horsepower civilian high-wing design was built by the Stinson Aircraft Company at Wayne, Michigan and first flew in 1939. It was marketed as the Model 105 and was first introduced to the public at the New York World's Fair. The three-place HW-75 featured two side-by-side seats and a third "jumpseat" in back on which a small passenger could sit facing sideways. Stylish, economical, spin resistant and easy to fly, the plane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
