Experimental determination of the aerodynamic coefficients of spinning bodies

The Aeronautical Journal, 2019
ABSTRACTTo accurately predict the probabilities of impact damage to aircraft from runway debris, it is important to understand and quantify the aerodynamic forces that contribute to runway debris lofting. These lift and drag forces were therefore measured in experiments with various bodies spun over a range of angular velocities and Reynolds numbers ...

Aerodynamic Coefficients of Stationary and Spinning Cricket Balls

, 2007
The flight of a cricket ball after leaving the hand of a bowler is, for given atmospheric conditions, principally governed by the speed of the ball, the angle of the seam to the direction of flight, any rotational spin applied to the ball, and the state of its outer surface with regard to the degree of wear and roughness.
