F1 Race Cars_运动Sports

　　f1 racecars are specially made for top competitions. every aspect of its design is aimed at raising its speed. now, the introduction of aviation materials and technologies has made them like special aircrafts running on racetracks. its acceleration in ten seconds is comparable to that of advanced jet fighters.

　　this soft material is carbon fiber. when processed under high pressure, it’s turned into a high strength material for the body of the car. its density is only half of that of ordinary steel, while its strength is double. this new material developed originally for aircraft and rockets is now used for constructing 85% of the parts of top f1 racecars.

　　the driver’s cab of f1 cars is designed like the cockpit of a jet fighter, and is tailor made according to the driver’s shape and size. nearly all the controls other than the brake and the accelerator are placed on the steering wheel or close to it. a light touch will make the computer execute the intent of the driver and seize every favorable opportunity in the race.

　　a racecar has 13,000 parts. in the past, their designs were all done line by line on the drawing board by the designer. now a computer will draw the three dimensional patterns of every part, and make any desired changes on the screen. but in construction, manual processing by skilled workers is still needed for some special requirements. in a workshop for f1 race cars, the construction materials are the most advanced ones of the 21st century, but the craftsmanship is that of old artisans.
　　wind tunnels used for aircraft design are now making the shape of f1 racecars more desirable in aerodynamics. every newly made wing plate will be subjected to wind tunnel testing to check if it meets design requirements.

　　the working principles of the chassis and the front and rear wing plates are similar to those of the wings of aircrafts. but the wings of an aircraft produce a lift, while the wings of an f1 race car produce a downforce, to avoid buoyancy and make the car cling tightly to the race track.

　　the engines of f1 racecars are mostly made of aluminum-titanium alloy, which can withstand a revolution of 18,000 rpm, and a maximum output of 800 horsepower, more than three times that of an ordinary car. to drive a racecar of less than 600 kg with such high power, is like pulling a brick with a horse. it can allow the car to accelerate from 0 to 100 kilometers per hour in 2.3 seconds.

　　the f1 racecar has now become a collection of the most advanced technologies. the actual significance of racecar production has gone beyond sports competition and has become a testing ground for new materials and technologies, implicating competitions between large carmakers. the f1 racing sport has in fact invited china, a huge consumer and manufacturer, to build a f1 race team and foster heroes on the racetracks.
