Wingfoot Express
The Wingfoot Express was Walt Arfons and Tom Green's jet-powered land speed record car, driven by Green to a record on October 2, 1964, after Walt suffered a heart attack just prior. The Express was powered by a Westinghouse J46 engine and hit the 413 mph record mark. History At a trade fair in Gary, Indiana in 1962, Arfons met Green, chief engineer for a torque wrench manufacturer. Although Green's only racing experience had been a year of stock car racing in New Mexico ten years previously, he was greatly interested in aerodynamics; this dovetailed perfectly with Arfons' interest in racing mechanics, and "Within ten minutes we were planning our assault on the world's land speed record" Green recalls. Green shortly provided plans for a three-wheeled land speed record car, which had to be changed to four wheels to meet FIA rules; from there on there was little change until the car was finished. Green's emphasis was on reducing aerodynamic drag by lowering the drag coefficien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The announcer at the drag strip laughingly an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

JATO
JATO (acronym for jet-assisted take-off) is a type of assisted take-off for helping overloaded aircraft into the air by providing additional thrust in the form of small rockets. The term ''JATO'' is used interchangeably with the (more specific) term RATO, for ''rocket-assisted take-off'' (or, in Royal Air Force, RAF parlance, RATOG, for ''rocket-assisted take-off gear''). Early experiments and World War II In 1927 the Soviet research and development laboratory Gas Dynamics Laboratory developed solid-propellant rockets to assist aircraft take-off and in 1931 the world's first successful use of rockets to assist take-off of aircraft were carried out on a :ru:У-1, U-1, the Soviet Union military aircraft designation systems, Soviet designation for a Avro 504 trainer, which achieved about one hundred successful assisted takeoffs. Successful assisted takeoffs were also achieved on the Tupolev TB-1. and Tupolev TB-3 Heavy Bombers. The official test of the Tupolev TB-1 in 1933 shorten ...

Solid-fuel Rocket
A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants ( fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder; they were used in warfare by the Arabs, Chinese, Persians, Mongols, and Indians as early as the 13th century. All rockets used some form of solid or powdered propellant up until the 20th century, when liquid-propellant rockets offered more efficient and controllable alternatives. Solid rockets are still used today in military armaments worldwide, model rockets, solid rocket boosters and on larger applications for their simplicity and reliability. Since solid-fuel rockets can remain in storage for an extended period without much propellant degradation and because they almost always launch reliably, they have been frequently used in military applications such as missiles. The lower performance of solid propellants (as compared to liquids) does not favor their use as primary propulsion in mode ...

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 older. ...

Shock Absorber
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types, the dissipated energy can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonneville Salt Flats
The Bonneville Salt Flats are a densely packed salt pan in Tooele County in northwestern Utah. A remnant of the Pleistocene Lake Bonneville, it is the largest of many salt flats west of the Great Salt Lake. It is public land managed by the Bureau of Land Management and is known for land speed records at the Bonneville Speedway. Access to the Flats is open to the public. The Flats are about 12 miles (19 km) long and 5 miles (8 km) wide, with a crust almost 5 ft (1.5m) thick at the center and less than one inch (2.5 cm) towards the edges. It is estimated to hold 147 million tons of salt, approximately 90% of which is common table salt. History Geologist Grove Karl Gilbert named the area after Benjamin Bonneville, a U.S. Army officer who explored the Intermountain West in the 1830s. In 1907, Bill Rishel and two local businessmen tested the suitability of the salt for driving by taking a Pierce-Arrow onto its surface. A railway line across the Flats was completed in 1910, ma ...

Myocardial Infarction
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to the coronary artery of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw. Often it occurs in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat or feeling tired. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock or cardiac arrest. Most MIs occur due to coronary artery disease. Risk factors include high blood pressure, smoking, diabetes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parachute
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag or, in a ram-air parachute, aerodynamic lift. A major application is to support people, for recreation or as a safety device for aviators, who can exit from an aircraft at height and descend safely to earth. A parachute is usually made of a light, strong fabric. Early parachutes were made of silk. The most common fabric today is nylon. A parachute's canopy is typically dome-shaped, but some are rectangles, inverted domes, and other shapes. A variety of loads are attached to parachutes, including people, food, equipment, space capsules, and bombs. History Middle Ages In 852, in Córdoba, Spain, the Moorish man Armen Firman attempted unsuccessfully to fly by jumping from a tower while wearing a large cloak. It was recorded that "there was enough air in the folds of his cloak to prevent great injury when he reached the ground." Early Renaissance The earliest evidence f ...

Dragstrip
A dragstrip is a facility for conducting automobile and motorcycle acceleration events such as drag racing. Although a quarter mile (1320 feet, 402 m) is the best known measure for a drag track, many tracks are eighth mile (201 m) tracks, and the premiere classes will run 1,000 foot (304.8 m) races. The race is begun from a standing start which allows three factors to affect the outcome of the race: reaction time, power/weight ratio, and traction. Features A dragstrip is a straight, purpose-built racetrack, typically an eighth, ten feet longer than three-sixteenths, or a quarter of a mile long (660/1,000/1320 feet, 201/304.8/402 m), with an additional ''shutdown area'' to allow vehicles room to stop after crossing the finish line. Common features also include a 'water box' where vehicles and motorcycles start their burnouts for tire clean-up and also to heat up their tires to improve traction. There is a set of lights known as a 'Christmas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrylic Glass
Poly(methyl methacrylate) (PMMA) belongs to a group of materials called engineering plastics. It is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Plexiglas, Acrylite, Astariglas, Lucite, Perclax, and Perspex, among several others ( see below). This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can also be used as a casting resin, in inks and coatings, and for many other purposes. Although not a type of familiar silica-based glass, the substance, like many thermoplastics, is often technically classified as a type of glass, in that it is a non-crystalline vitreous substance—hence its occasional historic designation as ''acrylic glass''. Chemically, it is the synthetic polymer of methyl methacrylate. It was developed in 1928 in several different laboratories by many chemists, such as William Chalmers, Otto Röhm, and Walter Bauer, and first brought ...
