Continental Tiara 8-380
The Continental Tiara series are a family of air-cooled, horizontally opposed aircraft engines. Designed and built by Continental Motors/TCM, the Tiara series were commercially unsuccessful, costing the company millions of dollars. Design and development Continental began development of the Tiara series in 1965.Leyes, p.119 At the time, CAE, Continental Motor's turbine engine subsidiary, had developed the T65, a small turboshaft engine which was being considered by Bell for its new Model 206 helicopter. Faced with having to fund the production tooling for the T65 in order to keep the price reasonable, or funding the Tiara series, Continental's corporate management chose to invest in the Tiaras. While the Tiara series were basically traditional boxer engines, they did have some unique features.Gunston, p.191 The engines had high rotational speeds, 0.5:1 gearing was used to reduce propeller speed, with the camshaft forming an extension of the propeller shaft.

Bell 206
The Bell 206 is a family of two-bladed, single- and twin-engined helicopters, manufactured by Bell Helicopter at its Mirabel, Quebec, plant. Originally developed as the Bell YOH-4 for the United States Army's Light Observation Helicopter program, it was not selected by the Army. Bell redesigned the airframe and successfully marketed the aircraft commercially as the five-place Bell 206A JetRanger. The new design was eventually selected by the Army as the OH-58 Kiowa. Bell also developed a seven-place LongRanger, which was later offered with a twin-engined option as the TwinRanger, while Tridair Helicopters offers a similar conversion of the LongRanger called the Gemini ST. The ICAO-assigned model designation "B06" is used on flight plans for the JetRanger and LongRanger, and the designation "B06T" is used for the twin-engined TwinRangers. Development Origins and JetRanger On October 14, 1960, the United States Navy solicited responses from 25 aircraft manufacturers to a req ...

Wet Sump
Within piston engines, a wet sump is part of a lubrication system whereby the crankcase sump is used as an integral oil reservoir. An alternative system is the dry sump, whereby oil is pumped from a shallow sump into an external reservoir.Wet sump and dry sump compared - https://www.knowyourparts.com/technical-resources/engine/oil-system-differences/#:~:text=Dry%20Oil%20Systems%20Wet%20sump%20systems%20store%20the,is%20used%20to%20pump%20oil%20from%20the%20motor. Piston engines are lubricated by oil which is pumped into various bearings, and thereafter allowed to drain to the base of the engine under gravity. In most production automobiles and motorcycles, which use a wet sump system, the oil is collected in a capacity pan at the base of the engine, known as the sump or oil pan, where it is pumped back up to the bearings by the internal oil pump. A wet sump offers the advantage of a simple design, using a single pump and no external reservoir. Since the sump is internal, t ...

Avgas
Avgas (aviation gasoline, also known as aviation spirit in the United Kingdom, 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 without lead since the 1970s to allow the use of catalytic converters for pollution reduction, the most commonly used grades of avgas still contain tetraethyllead, tetraethyl lead, a toxic lead-containing additive used to aid in lubrication of the engine, increase octane rating, and prevent engine knocking (spark-knock). There are ongoing efforts to reduce or eliminate the use of lead in aviation gasoline. Kerosene-based jet fuel is formulated to suit the requirements of gas turbine, turbine engines which have no octane requirement and operate over a much wider flight envelope than piston engines. Kerosene is also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trident Trigull
The Trident TR-1 Trigull is a Canadian amphibious aircraft that was developed by Trident Aircraft of Burnaby, British Columbia and later Sidney, British Columbia. The aircraft was intended to be supplied as a complete ready-to-fly certified aircraft. The company encountered financial difficulties and only three prototypes were ever built.Plane and Pilot: ''1978 Aircraft Directory'', page 77. Werner & Werner Corp, Santa Monica CA, 1977.

Spencer Air Car
The Spencer Amphibian Air Car is an American light amphibious aircraft. The name was first used in 1940 for a prototype air vehicle that developed into the Republic Seabee. The name was later used by its designer Percival Spencer for a series of homebuilt amphibious aircraft roughly based on the Seabee design. Design and development Percival H. Spencer formed the Spencer-Larsen Aircraft Corporation and designed the SL-12C amphibian. Disenfranchised with corporate policies in the development of the SL-12C amphibian, Spencer started the Spencer Amphibian Air Car in 1940. The original Spencer Amphibian Air Car was test flown in 1941. The aircraft was put into storage due to wartime restrictions in effect in the US during World War II. The aircraft and rights to its design were sold to Republic as the "Seabee" in 1943. After leaving Republic, he designed the on-off two-seat Air Car. In 1968, Spencer and retired USAF Col. Dale L. "Andy" Anderson formed a new company to market a fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cierva CR Twin
The Cierva CR Twin (originally designated CR LTH.1 and also known as the Grasshopper III) was a five-seat utility helicopter that first flew in the UK in 1969. It was a joint development between Cierva Autogiro Company and Rotorcraft now a subsidiary of Cierva, based on the dynamic systems of the latter company's Grasshopper design. A new, highly streamlined pod-and-boom fuselage was married to the Grasshopper's coaxial rotor system, and the new aircraft registered ''G-AWRP'' first flew on 18 August 1969. Two further prototypes followed, ''G-AXFM'' later in 1969 and ''G-AZAU'' in 1971, this latter example fitted with 210 hp Continental IO-360-D engines in place of the Rolls-Royce Continental O-300 units of the first two machines. Financial backing could not be obtained for further development, and the project was abandoned by 1975. The first prototype is preserved at The Helicopter Museum in Weston-super-Mare Weston-super-Mare ( ) is a seaside town and civil parish ...

1973 Oil Crisis
In October 1973, the Organization of Arab Petroleum Exporting Countries (OAPEC) announced that it was implementing a total oil embargo against countries that had supported Israel at any point during the 1973 Yom Kippur War, which began after Egypt and Syria launched a large-scale surprise attack in an ultimately unsuccessful attempt to recover the territories that they had lost to Israel during the 1967 Six-Day War. In an effort that was led by Faisal of Saudi Arabia, the initial countries that OAPEC targeted were Canada, Japan, the Netherlands, the United Kingdom, and the United States. This list was later expanded to include Estado Novo (Portugal), Portugal, Rhodesia, and South Africa. In March 1974, OAPEC lifted the embargo, but the price of oil had risen by nearly 300%: from US to nearly US globally. Prices in the United States were significantly higher than the global average. After it was implemented, the embargo caused an oil crisis, or "shock", with many short- and long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camshaft
A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers. Camshafts in piston engines are usually made from steel or cast iron, and the shape of the cams greatly affects the engine's characteristics. History Trip hammers are one of the early uses of a form of cam to convert rotating motion, e.g. from a waterwheel, into the reciprocating motion of a hammer used in forging or to pound grain. Evidence for these exists back to the Han dynasty in China, and they were widespread by the medieval period. Camshafts were first described by Ismail al-Jazari in 1206. Once the rotative version of the steam engine was developed in the late 18th century, the operation of the valve gear was usually by an eccentric, which turned the rotation of the crankshaft i ...

1 Gearing
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
