The Aerodynamic Drag of Parafoils
The parafoil is an aerodynamic decelerator that uses the concept of parachute and airfoil aerodynamics. The device has been used as a parachute for high-precision delivering of payload (military and civilian), to recover sounding rockets, for various tethered applications (to carry instrumentation for weather survey, air pollution measurements, radar tracking systems), and as recreational parac...
متن کاملThe flight of a golf ball
A skilled golfer hitting a drive can accelerate his club head from zero to 120 miles per hour in the quarter of a second before making contact with the ball. As a result, the ball leaves the tee with a typical speed of 175 miles per hour and at an angle of 11◦ to the ground. From that moment the golfer no longer exercises control. The trajectory of the ball is determined by the laws of physics....
متن کاملNumerical study on the aerodynamic drag of drafting cyclist groups
This paper presents a Computational Fluid Dynamics (CFD) investigation of the aerodynamic effects of drafting in cycling. In drafting, cyclists ride close behind each other to reduce aerodynamic drag. The CFD simulations for single cyclists and for a group of two cyclists are successfully compared with wind-tunnel measurements. Both CFD simulations and wind tunnel measurements show that also th...
متن کاملAerodynamic drag in cycling: methods of assessment.
When cycling on level ground at a speed greater than 14 m/s, aerodynamic drag is the most important resistive force. About 90% of the total mechanical power output is necessary to overcome it. Aerodynamic drag is mainly affected by the effective frontal area which is the product of the projected frontal area and the coefficient of drag. The effective frontal area represents the position of the ...
متن کاملAerodynamic drag of modern soccer balls
Soccer balls such as the Adidas Roteiro that have been used in soccer tournaments thus far had 32 pentagonal and hexagonal panels. Recently, the Adidas Teamgeist II and Adidas Jabulani, respectively having 14 and 8 panels, have been used at tournaments; the aerodynamic characteristics of these balls have not yet been verified. Now, the Adidas Tango 12, having 32 panels, has been developed for u...
