Aerodynamic Drag
Reducing Aerodynamic DragMay 06, 2012
Reducing a vehicle's aerodynamic drag can improve a car's fuel economy, say automakers. Not only can designers make it easier for a car to push through the air, automakers report drivers can also pull their weight by removing unused bike, ski or luggage racks off the vehicle's roof. Available video includes general views of the Chevrolet Volt and other aerodynamically designed cars, soundbites on improving fuel economy and an edited package on how to save on gas by reducing a car's wind resistance.
Understanding aerodynamic drag dependency of shape.Jan 21, 2012
The effects of hydrodynamics or aerodynamics resistance and drag are here shown by 4 different shapes submerged in water each pulled by the same weight and each having the same cross sectional area. The drag for each of the shapes are different only due to their more or less aerodynamically form. Taken from the exhibition at the Technical Museum in Berlin 2011 More Info: en.wikipedia.org
TransFoil Aerodynamic Truck Trailer Skirts Save Diesel FuelMay 04, 2012
TransFoil Aerodynamic Trailer Skirts reduce the aerodynamic drag of tractor trailers, thereby reducing diesel fuel consumption by more than 5%, resulting in a significant savings to fleets and owner operators.

The Aerodynamics of FlightMay 19, 2012
The creator of this video allows full use of its contents for educational purposes. geardownfs.com This video covers the basic aerodynamics that allow for all different types of aircraft to fly. Everything in this video should only be applied in theory flight simulation. I am not a real world pilot, and therefore cannot testify on behalf of the actual processes of real world aviation.

Low Aero Drag Pickup Cap Mk2Mar 22, 2012
This is a revised version of the aerodynamic pickup cap I designed earlier. This one is probably more realistic for the mid-sized pickup it is based on. The older version is here: www.youtube.com On the new blue one, on the back you can see the darker area that is the face of the older pink design.

Aerodynamic Drag and Stability of DeceleratorsFeb 06, 2012
Film of tests conducted at NASA Langley Research Center by John T. McShera, He published a technical report, TN D-1601, in 1963. Tests show the aerodynamic drag and stability characteristics of towed inflatable decelerators of various shapes. Tests are run at supersonic speed. The tunnel used was not recorded. Original film repeated itself and is left as found on the 16mm film reel. For more on NASA Langley Research Center, see crgis.ndc.nasa.gov

NATURAL VENTILATION FOR REDUCING DRAGOct 19, 2011
A must see film on the newest breakthrough in trailer aerodynamics. Reducing drag and saving fuel on a tractor trailers using natural ventilation is environmentally friendly in manufacturing, installation and use. A 1/10 of a MPG on all over the road trucks today equates to saving 1 million gallons a day. You can help save the environment our natural resources and become less dependent on foreign oil by moving this technology forward. Pass this to two friends and have them do the same. Please visit our web site at truckitservices.com and look at PROOF OF MPG on the navigation bar.
Ae86 Aero Testing (Drag Coefficient) ハチロク ドラッグ係数Feb 24, 2012
its not a million dollar wind tunnel test...but hey i wanted to see for myself how the ae86 reacts...if you guys find vids of ae86 or older corollas please post them up...we need this info The drag coefficient is a common metric in automotive design, where designers strive to achieve a low coefficient. Minimizing drag is done to improve fuel efficiency at highway speeds, where aerodynamic effects represent a substantial fraction of the energy needed to keep the car moving. Indeed, aerodynamic drag increases as the square of speed. Aerodynamics are also of increasing concern to truck designers, where a lower drag coefficient translates directly into lower fuel costs. About 60% of the power required to cruise at highway speeds is used to overcome air drag, and this increases very quickly at high speed. Therefore, a vehicle with better aerodynamics will be more fuel efficient.
Improved aerodynamicsApr 21, 2012
Low aerodynamic drag helps to save fuel and therefore to reduce emissions of CO2 and other pollutants. The improved aerodynamics of the TGX and TGS series were achieved through numerous intelligent and design-based solutions. These include: The new spoiler lip with cut-off edge on the bumper. Smaller openings on the outer side of the headlights. Striking wind deflectors on the left and right. New one-piece mirror casings with water drain management. A new roof spoiler for the XLX cab, which surrounds the opening of the sun roof and also provides defined air guidance to improve ventilation in the cab. As a result of the redesign, the new air dams of the TGX and TGS increase the air flow to the radiator by 15 %. The fan therefore switches on less often -- auxiliary power requirements are reduced. The drag coefficient of the new vehicles has been improved by up to 6 %. This provides the customer with a fourfold benefit: Fuel savings of around 3 % 25 % less noise in the interior Less dirt on the vehicle, particularly on mirror surfaces and side windows Greater reliability thanks to optimised engine cooling.
2009 Space Technology Hall of Fame Inductees.Aug 27, 2010
During the 1970s and 1980s, researchers at Dryden Flight Research Center conducted numerous tests to refine the shape of trucks to reduce aerodynamic drag and improved efficiency. During the 1980s and 1990s, a team based at Langley Research Center explored controlling drag and the flow of air around a moving body. Aeroserve Technologies Ltd., of Ottawa, Canada, with its subsidiary, Airtab LLC, in Loveland, Colorado, applied the research from Dryden and Langley to the development of the Airtab vortex generator. Airtabs create two counter-rotating vortices to reduce wind resistance and aerodynamic drag of trucks, trailers, recreational vehicles, and many other vehicles.

What is drag?Jul 18, 2010
This movie teaches the aerodynamic concept of drag, important for vehicles in movement. Because it is intended for twelve-year-old children, it uses simple daily situations and every day activities as examples.
