McLaren M20
The McLaren M20 was a sports prototype developed by McLaren for the 1972 season of the Canadian-American Challenge Cup. It served as a replacement for the team's M8Fs, but it later became the final Can-Am design created by McLaren before the team left the series after failing to secure the 1972 championship title. M20s continued to be entered by private teams until the Can-Am championship was canceled at the conclusion of the 1974 season. McLaren driver Denny Hulme won two races during the 1972 season while Scooter Patrick won a single event in 1974 with a privately entered M20. Development When McLaren designed their replacement for 1971's M8Fs, one of the team's primary goals was to improve the cooling structure of the cars in order to allow their racing drivers, Denny Hulme and Peter Revson, more comfort during races. The M8F, as with previous McLaren sports cars, featured a large radiator mounted in the nose of the car, through which air was drawn from openings in th ...

Hewland
Hewland is a British engineering company, founded in 1957 by Mike Hewland, which specialises in racing-car gearboxes. Hewland currently employ 130 people at their Maidenhead facility and have diversified into a variety of markets being particularly successful in electric vehicle transmission supply. Hewland are currently supplying into Formula 1, Formula E, DTM, LMP, RallyCross, Prototype and GT Sportscar. History Mike Hewland ran a small engineering business at Maidenhead in the UK with the speciality in gear cutting. In 1959, Bob Gibson-Jarvie, the Chief Mechanic of UDT Laystall racing team running Cooper F2 cars, sought help from Hewland as gearbox troubles were experienced. The result of this request came out as six successful gearboxes being designed and built in 1959, and Hewland was in the gearbox business. The first transaxle product, the Hewland Mk.I of 1960, was a minor modification of the Volkswagen Beetle 4 speed transaxle used upside-down with custom made differ ...

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 ...

Airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. Foils of similar function designed with water as the working fluid are called hydrofoils. The lift on an airfoil is primarily the result o ...

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 Aircraft#Heavier than air – aerodynes, 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 simu ...

Road & Track
''Road & Track'' (stylized as ''R&T'') is an American automotive enthusiast magazine. It is owned by Hearst Magazines and is published 6 times per year. The editorial offices are located in New York, New York. History ''Road & Track'' (often abbreviated ''R&T'') was founded by two friends, Wilfred H. Brehaut, Jr. and Joseph S. Fennessy, in 1947, in Hempstead, New York. Published only six times from 1947 to 1949, it struggled in its early years. By 1952, regular contributor and editor John R. Bond and his wife Elaine had become the owners of the magazine, which then grew until its sale to CBS Publications in 1972. The ampersand (&) in the title was introduced in 1955 by then Editor Terry Galanoy, who replaced the word "and" in the magazine's name because the words Road and Track were graphically too long for newsstand-effective recognition. In 1988, Hachette Filipacchi Media took ownership of the magazine. In October 2008, Matt DeLorenzo became editor-in-chief, succeeding Tho ...

Radiator
Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in cars, buildings, and electronics. A radiator is always a source of heat to its environment, although this may be for either the purpose of heating this environment, or for cooling the fluid or coolant supplied to it, as for automotive engine cooling and HVAC dry cooling towers. Despite the name, most radiators transfer the bulk of their heat via convection instead of thermal radiation. History The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, having received a radiator patent in 1857, but American Joseph Nason developed a primitive radiator in 1841 and received a number of U.S. patents for hot water and steam heating. ...

McLaren M8F
The McLaren M8A was a race car developed by driver Bruce McLaren and his Bruce McLaren Motor Racing team for their entry in 1968 Can-Am season. The M8A and its successors dominated Can-Am racing for four consecutive Can-Am seasons, until the arrival of the Porsche 917. Development M8A The M8A was an evolution of the previous M6A design, and featured an all-aluminium seven-litre Chevrolet big-block V8 as a semi-stressed chassis member. The engines were built by Gary Knutson and initially developed 620 bhp. Two complete M8A race cars and one spare tub were built. M8B The M8B was developed for the 1969 Can-Am season. The most noticeable difference was that the rear wing was now mounted high on pylons, like the Chaparral 2E. The wing mounting pylons passed through the bodywork to attach directly to the suspension uprights. This arrangement allowed McLaren to run softer springs than would have been required had the massive rear wing been attached to the bodywork. The body w ...

1974 Can-Am Season
The 1974 Canadian-American Challenge Cup was the ninth and final season of the original Can-Am auto racing series. It consisted of FIA Group 7 racing cars running half hour ''Sprint'' races followed by hour-long ''Cup'' races. It began June 16, 1974, and was cancelled after the fifth round on August 25, 1974. Following the cancellation of the series, many teams turned to the new Camel GT Challenge, although the cars were not of the same type as had been used in Can-Am. The Can-Am name would return in 1977, although the formula used would vary greatly from the original series, concentrating instead on open-wheel An open-wheel single-seater (often known as formula car) is a car with the wheels outside the car's main body, and usually having only one seat.

Privateer (motorsport)
In motorsport, a privateer is usually an entrant into a racing event that is not directly supported by an automobile or motorcycle manufacturer. Privateers teams are often found competing in rally, circuit racing and motorcycle racing events and often include competitors who build and maintain their own vehicles and motorcycles. In previous Formula One seasons, privately owned teams would race using the chassis of another team or constructor in preference to building their own car; the Concorde Agreement now prohibits this practice. Increasingly the term is being used in an F1 context to refer to teams who are not at least part-owned by large corporations, such as Williams F1. Many privateer entrants compete for the enjoyment of the sport, and are not paid to be racing drivers. See also *Contrast: Factory-backed In motorsports, a factory-backed racing team or driver is one sponsored by a vehicle manufacturer in official competitions. As motorsport competition is an expen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
