A wing is designed so airflow creates a low-pressure system over the top of the wing and a relative high-pressure system underneath. If you're interested in a few drafting success stories, take a look at the next page. "You'll see a guy at Talladega moving around and you know that whatever line he gets in front of moves faster.". [18][19] The Air Force has also tested vortex surfing with C-17s using auto pilot in 2012, and indicated a 10% fuel saving. But physics tells us that every action has an equal and opposite reaction. 51 views. "Three cars will run faster than two, and five cars will run faster than three," he said. Drivers will often take advantage of this in the last laps by getting close to a lead competitor in exactly the wrong spot and unsticking their tires by manipulating their downforce stream. This pressure differential also explains why windows blow out of well-sealed homes during a hurricane. Kyle Busch is largely responsible for a different type of bump drafting, which is now referred to as "two-car drafting"[citation needed] and "tandem drafting". Drafting and drag go hand-in-hand. At superspeedways like Alabama's Talladega and Florida's Daytona International, where speed is limited by a restrictor plate rule, long lines of drafting cars take advantage of the car in front to allow greater speeds and better fuel efficiency. This sequence is by and large assigned indiscriminately, either by drawing draft order numbers out of a hat or pulling numbers from a deck of cards. What drag does to the Cup Car is to slow it down. Thankfully, cars have been set up to reduce the injury rates of drivers, which is why all drivers need to learn about the science of drafting.if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[250,250],'motorracingsports_com-medrectangle-3','ezslot_3',113,'0','0'])};__ez_fad_position('div-gpt-ad-motorracingsports_com-medrectangle-3-0');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[250,250],'motorracingsports_com-medrectangle-3','ezslot_4',113,'0','1'])};__ez_fad_position('div-gpt-ad-motorracingsports_com-medrectangle-3-0_1'); .medrectangle-3-multi-113{border:none !important;display:block !important;float:none !important;line-height:0px;margin-bottom:15px !important;margin-left:auto !important;margin-right:auto !important;margin-top:15px !important;max-width:100% !important;min-height:250px;min-width:250px;padding:0;text-align:center !important;}. Side drafting can also work, but this is used more for passing than gaining speed. Racing cars just reverse the strategy by reducing the pressure underneath the car as compared to that above the car.

That is how drag works. Brett Bodine, now the director of cost research for NASCAR's Research and Development Center, began his career as a NASCAR Truck Series driver. Small savings like this add up over a tank of gas. However, this year the host can pause the clock, which is great for getting large numbers into a race. Below are a few examples of NASCAR wins where drafting attack and defense were critical to success. By tailgating, the same effects of reducing drag will pull a car along in the wake of the truck and add a few miles per gallon as the smaller car's engine works less. The trailing car is not allowed to stay in contact with the bumper of the leading car which will amount to tandem trailing.

Normal drafting, bump drafting, and side drafting are all permitted., Normal drafting is the most basic form of drafting and involves one car closely tailing the leading car in order to get inside its slipstream and reduce overall drag.Normal drafting benefits both cars: it benefits the following car by reducing the drag of airflow in front of it, and it helps the leading car by reducing turbulence behind it, improving its own drag.However, as with all forms of drafting, normal drafting can be dangerous, as if any one car veers out of the formation, a wreck could occur.. Instead, the new design was raced in all 36 races on the 2008 schedule and is currently the only car design NASCAR allows to race.

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. It takes more than a lead foot and nerves of steel. That's all part of the plan to reduce drag and increase speed. Drafting also reduces fuel consumption throughout the race. For the car leading, it reduces the turbulence behind the car, which slows the car down, and it reduces the pressure on the nose of the car that is following. 3 interesting facts on how NASCAR telemetry works, A Beginners Guide to NASCAR: 6 Highlights of What NASCAR Is Like.
