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 ...

Formula One Car
A Formula One car (also known as an F1 car) is a single-seat, open-cockpit, open-wheel formula racing car with substantial front and rear wings, and an engine positioned behind the driver, intended to be used in competition at Formula One racing events. The regulations governing the cars are unique to the championship and specify that cars must be constructed by the racing teams themselves, though the design and manufacture can be outsourced. Formula One cars are the fastest cars in the world around a race track, owing to very high cornering speeds achieved through the generation of large amounts of aerodynamic downforce. As a result of the amount of braking force and the total cornering envelope of a Formula One car (by the friction component of the tyre, the mass of the machine and the downforce generated); Formula One drivers experience frequent lateral g-loadings in excess of five g, and peak cornering forces of up to seven lateral g.

Diffuser (automotive)
A diffuser, in an automotive context, is a shaped section of the car rear which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere. It works by providing a space for the underbody airflow to decelerate and expand (in volume, as density is assumed to be constant at the speeds that cars travel) so that it does not cause excessive flow separation and drag, by providing a degree of " wake infill" or more accurately, pressure recovery. The diffuser itself accelerates the flow in front of it, which helps generate downforce. This is achieved by creating a change in velocity of the air flowing under the diffuser by giving it a rake angle which in turn generates a change in pressure and hence increases downforce. __TOC__ Overview When a diffuser is used, the air flows into the underbody from the front of the car, accelerates and reduces pressure.

Grip (autoracing)
The following is a glossary of terminology used in motorsport, along with explanations of their meanings. 0–9 ;1–2 finish: When two vehicles from the same team finish first and second in a race. Can be extended to 1–2–3 or 1–2–3–4, etc. depending on a combination of racing series and team size. ; 107% rule: Often used in Formula One or other racing series, it is a rule where the driver must qualify the car within 107% of the polesitter's time to be allowed to compete. Variations of this may be used to monitor drivers and warn them to reach the required pace or be parked (disqualified). Similarly, the IndyCar Series uses a 105% rule, and NASCAR has a 115% rule, mainly for performance on track, though IndyCar and NASCAR often adjust the threshold for tracks with very abrasive surfaces (such as Atlanta Motor Speedway) where lap times can be considerably faster with less worn tires. ;200 MPH Club: A lifetime "membership" awarded by the SCTA or another sanctioni ...

Slipstreaming
Drafting or slipstreaming is an aerodynamic technique where two vehicles or other moving objects are caused to align in a close group, reducing the overall effect of drag due to exploiting the lead object's slipstream. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure required to maintain a certain speed and can also slightly reduce the energy expenditure of the lead vehicle or object. Drafting in sport Drafting is used to reduce wind resistance and is seen most commonly in bicycle racing, motorcycle racing, car racing, and speedskating, though drafting is occasionally used even in cross-country skiing, downhill skateboarding, and running. Some forms of triathlon allow drafting. Drafting occurs in swimming as well: both in open-water races (occurring in natural bodies of water) and in traditional races in competition pools. In a competition pool a swimmer may hug the lane line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark Webber (racing Driver)
Mark Alan Webber (born 27 August 1976) is an Australian retired professional racing driver who competed in Formula One from 2002 to 2013 and the FIA World Endurance Championship (WEC) between 2014 and 2016. He is a champion of the 2015 FIA WEC for Porsche with German Timo Bernhard and New Zealander Brendon Hartley. Webber began karting at age 12 or 13 and achieved early success, winning regional championships before progressing to car racing in the Australian Formula Ford Championship and the British Formula 3 Championship.

Horizontal Stabilizer
A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabiliser, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabiliser and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DeltaWing
The DeltaWing is a racing car designed by American race car designer and engineer Ben Bowlby and debuted at the 2012 24 Hours of Le Mans. The entry was run under the Project 56 name, composed of Ben Bowlby (design), Dan Gurney's All American Racers (constructor), Duncan Dayton's Highcroft Racing (racing team) and International Motor Sports Association owner Don Panoz (managing partner). Nissan's NISMO division provided the engine in return for naming rights for part of 2012. The DeltaWing is built and maintained at Panoz headquarters in Braselton, Georgia U.S.A. History The project began in January 2009, when Bowlby created a potential new IndyCar Series design for the 2012 season. With financial backing from Chip Ganassi, owner of Chip Ganassi Racing, the prototype was unveiled in February 2010 at the Chicago Auto Show. Ganassi and the team partners own the car and its patents. In July 2010, IndyCar chose a Dallara design instead. Bowlby then worked with Don Panoz to pr ...

1999 24 Hours Of Le Mans
The 1999 24 Hours of Le Mans was the 67th 24 Hours of Le Mans, and took place on 12 and 13 June 1999. The race had a large number of entries in the fastest Le Mans Prototype classes, with Audi, BMW, Ferrari, Lola Cars, Mercedes-Benz, Nissan, Panoz, Riley & Scott, and Toyota all represented. The BMW V12 LMR of Yannick Dalmas, Pierluigi Martini, and Joachim Winkelhock won overall, with their car's reliability and fuel economy allowing them to beat their faster rivals. Pre-race 1999 saw another increase in manufacturers involvement. Although Porsche did not send a team to contest in the prototype classes, Toyota retained their three updated GT-Ones, now moved to the LMGTP class due to the demise of GT1, while Mercedes-Benz debuted three new CLR LMGTPs. Nissan instead moved from GT1 to an open cockpit LMP, as did Panoz. Newcomer Audi attempted to try their hand at both classes, with two open cockpit R8Rs and two closed cockpit R8Cs. BMW continued with their open cockpit LMP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pit Stop
In motorsports, a pit stop is a pause for refuelling, new tyres, repairs, mechanical adjustments, a driver change, as a penalty, or any combination of the above. These stops occur in an area called the pits, most commonly accessed via a pit lane which runs parallel to the start/finish straightaway of the track and is connected to it at each end. Along this lane is a row of garages (typically one per team or car) outside which the work is done in a ''pit box''. Pit stop work is carried out by the pit crew of up to twenty mechanics, depending on the series regulations, while the driver often waits in the vehicle (except where a driver change is involved or in motorbike racing). The term is also used generically to describe a short break in a journey. Location and terminology Depending on the circuit, the garage may be located on pit lane or in a separate area. In most series, the order of the teams' pit boxes is assigned by points standings, race results, or previous qualifyi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercedes-Benz CLR
The Mercedes-Benz CLR was a set of racing cars developed for Mercedes-Benz through a collaboration with in-house tuning division Mercedes-AMG and motorsports specialists HWA GmbH. Designed to meet Le Mans Grand Touring Prototype (LMGTP) regulations, the CLRs were intended to compete in sports car events during 1999, most notably at the 24 Hours of Le Mans which Mercedes had last won in . It was the third in a series of sports cars raced by Mercedes, following the CLK GTRs and CLK LMs that had debuted in 1997 and 1998 respectively. Like its predecessors the CLR retained elements of Mercedes-Benz's production cars, including a V8 engine loosely based on a design used in some models as well as bodywork based on the Mercedes-Benz C208, CLK and Mercedes-Benz C215, CL-Classes. The CLR's bodywork was lower in overall height than that used on the CLKs to produce less drag. Three CLRs were entered for Le Mans in 1999 after the team performed nearly of testing. The cars suffered a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
