Art Arfons
Arthur Eugene Arfons (February 3, 1926 – December 3, 2007) was the world land speed record holder three times from 1964 to 1965 with his '' Green Monster'' series of jet-powered cars, after a series of ''Green Monster'' piston-engine and jet-engined dragsters. He subsequently went on to field a succession of ''Green Monster'' turbine-engined pulling tractors, before returning to land speed record racing. He was announced as a 2008 inductee in the International Motorsports Hall of Fame three days after his death. Family Art Arfons' father, Tom, was born in Greece and came to the United States at age 14. He settled in Akron, Ohio, where Art was born. Tom died in 1950, at age 52. His mother, Bessie, was half Cherokee, and died in 1983 at age 84. Arfons had two half brothers by his mother — Walt Arfons, ten years older, who was to become his partner and later competitor in motor sports, and Dale, eight years older, as well as one sister "Lou", eighteen months old ...

Green Monster (automobile)
The ''Green Monster'' was the name of several vehicles built by Art Arfons and his half brother Walt Arfons. These ranged from dragsters to a turbojet-powered car which briefly held the land speed record three times during 1964 and 1965. The land speed record ''Green Monster'' set the absolute record three times during the close competition of 1964 and 1965. It was powered by a General Electric J79 taken from an F-104 Starfighter. The jet engine had a four-stage afterburner. Early dragsters The first ''Green Monster'' appeared in 1952. It was a three-wheeled dragster powered by an Oldsmobile six cylinder engine, and painted with left-over green tractor paint. The name was applied on the car's first outing by the track announcer, Ed Piasczik (Paskey), who laughingly said "Okay folks here it comes; The Green Monster", and it stuck to all Arfons' creations. The car only reached , short of the fastest car, but by 1953, ''Green Monster 2'', a long six wheeled car powered by an Al ...

Walt Arfons
Walter Charles Arfons (December 10, 1916 – June 4, 2013) was the half brother of Art Arfons, his former partner in drag racing, and his competitor in jet-powered land speed record racing. Along with Art, he was a pioneer in the use of aircraft jet engines for these types of competition. Walt was born Walter Stroud, on 10 December 1916 in Muncie, IN. His mother, Bessie, was half Cherokee, and died in 1983 at age 84. Walt had one brother, Dale, two years younger, as well as his ten years younger half-brother Art and an eight and a half years younger half-sister "Lou", both from his mother's marriage to Tom Arfons. Arfons' family operated a feed mill in rural Springfield Township, Ohio, where the Arfons brothers exercised their mechanical skills and ingenuity. Walt began building dragsters with Art in 1952; their first car was a three-wheeler with an Oldsmobile six-cylinder engine, and an Oliver farm tractor green paint finish.

Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Various forms of brackets are used in mathematics, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petty Officer Second Class
Petty officer second class is the fifth enlisted rank in the U.S. Navy and the U.S. Coast Guard, just above petty officer third class and below petty officer first class, and is a non-commissioned officer. It is equivalent to the rank of sergeant in the Army and Marine Corps, and staff sergeant in the Air Force. Overview Similar to petty officer third class, advancement to petty officer second class is dependent on time in service, performance evaluations by superiors, and rate (technical specialty) examinations. The advancement cycle is currently every 6 months. Only a certain number of billets (job openings for this rate) open up biannually and all third-class petty officers compete. The top scorers are chosen for advancement, but only in sufficient quantities to fill the billets available. Job description Petty Officers serve a dual role as both technical experts and as leaders. Unlike the sailors below them, there is no such thing as an "undesignated Petty Officer. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Monster Nose
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while red w ...

Downforce
Downforce is a downwards lift force created by the aerodynamic features of a vehicle. If the vehicle is a car, the purpose of downforce is to allow the car to travel faster by increasing the vertical force on the tires, thus creating more grip. If the vehicle is a fixed-wing aircraft, the purpose of the downforce on the horizontal stabilizer is to maintain longitudinal stability and allow the pilot to control the aircraft in pitch. Fundamental principles The same principle that allows an airplane to rise off the ground by creating lift from its wings is used in reverse to apply force that presses the race car against the surface of the track. This effect is referred to as "aerodynamic grip" and is distinguished from "mechanical grip", which is a function of the car's mass, tires, and suspension. The creation of downforce by passive devices can be achieved only at the cost of increased aerodynamic drag (or friction), and the optimum setup is almost always a compromise between ...

Wing
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift. Lifting structures used in water include various foils, such as hydrofoils. Hydrodynamics is the governing science, rather than aerodynamics. Applications of underwater foils occur in hydroplanes, sailboats and submarines. Etymology and usage For many centuries, the word "wing", from the Old Norse ''vængr'', referred mainly to the foremost limbs of birds (in addition to the architectural aisle).

Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis f ...

Clutch
A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears. In a torque-controlled drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at th ...

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.
