Wind TunnelsUsed to study the effect of air moving pass solid

objectsServes as research tool used in aerodynamic

studiesInitially proposed as a means of studying

vehicles, mainly airplanes, in free flightLater, effects of wind on man made structures

and other objects were studied, also recreational use

These man made structures could include bikes, cars, or bridges
