Lycoming YO-233
The Lycoming IO-233 is a non-certified four-cylinder, air-cooled, horizontally opposed piston aircraft engine that produces between and . The IO-233 is a development of the Lycoming O-235, which is itself a derivative of the older Lycoming O-233 engine. Development The IO-233 was announced by the company at AirVenture on 28 July 2008 as a new engine for light sport aircraft. The engine was conceived as a lightened version of the Lycoming O-235 by company engineers who were building their own kit LSAs and found that there was no powerplant that met their requirements for power output and weight, with the ability to burn either 100LL avgas or unleaded automotive fuel. The resulting engine weighs less than the O-235 and incorporates a throttle body injector system with a tuned intake manifold and dual electronic ignition, or optionally a carburetor in place of the throttle body injector to save further cost and weight. The engine has a 2400-hour time between overhauls. Addit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Falcon LS
The Falcon LS is a two-seat, low wing, light sport aircraft originally produced by Corvus Aircraft in Hungary as the Corvus Phantom and imported into the US by T&T Aviation between 2008–2010 and by Renegade Light Sport 2010–present.Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 78. WDLA UK, Lancaster UK, 2011. ISSN 1368-485XTacke, Willi; Marino Boric; et al: ''World Directory of Light Aviation 2015-16'', page 76. Flying Pages Europe SARL, 2015. There is disagreement between Corvus Aircraft and Renegade Light Sport as to whether the design has been licensed or reverse engineered. Design and development On 6 October 2010 the Falcon LS became the first airplane to fly with the Lycoming IO-233-LSA engine. Originally T&T Aviation was selected by Lycoming to help develop their IO-233-LSA engine. When Renegade bought out T&T Aviation they continued the engine development partnership with Lycoming.

2000s Aircraft Piston Engines
S, or s, is the nineteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Origin Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a phoneme, so the derived Greek letter sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter '' samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ) "to hiss". The original name of the letter "sigma" may have been ''san'', but due to the compli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasoline
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades. Tetraethyl lead and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avgas
Avgas (aviation gasoline, also known as aviation spirit in the UK) is an aviation fuel used in aircraft with spark-ignited internal combustion engines. ''Avgas'' is distinguished from conventional gasoline (petrol) used in motor vehicles, which is termed ''mogas'' (motor gasoline) in an aviation context. Unlike motor gasoline, which has been formulated since the 1970s to allow the use of platinum-content catalytic converters for pollution reduction, the most commonly used grades of avgas still contain tetraethyllead (TEL), a toxic substance used to prevent engine knocking (premature detonation). There are ongoing experiments aimed at eventually reducing or eliminating the use of TEL in aviation gasoline. Kerosene-based jet fuel is formulated to suit the requirements of turbine engines which have no octane requirement and operate over a much wider flight envelope than piston engines. Kerosene is also used by most diesel piston engines developed for aviation use, such as tho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Valve
An overhead valve (OHV) engine, sometimes called a ''pushrod engine'', is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first succ ...

Denney Kitfox
The Denney Kitfox is a series of small side-by-side, two-seat, high-wing, single engine kit aircraft, designed and originally manufactured by Dan Denney and his company Denney Aerocraft of Boise, Idaho. The aircraft is amateur-built and not type-certified. Over 4500 kits have been delivered in 42 different countries. A derivative of the Avid Flyer, the Kitfox was an early kit plane to feature quickly-folding wings that greatly simplify carriage and storage. The appeal of the aircraft was that it could be built in a two-car garage. Then it would be towed to the airport with the wings folded. The landing gear may be easily converted to floats or skis. Development and history First flown in November 1984 from the Denney Aerocraft factory in Boise, the Model 1 Kitfox was a two-seat STOL taildragger aircraft capable of flying from unimproved strips. The design was originally intended to use a new radial engine then in development and the early Kitfoxes had round cowl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...
