Abstract
This paper describes the aerodynamic characteristics of a non-spinning rugby ball and its flight trajectory on the basis of the unsteady aerodynamic data obtained from the non-spinning ball. It has been found that the side force oscillates with the time. The oscillation depends on the angle of attack and the position of the lace. As the angle of attack increases, the amplitude of the side force oscillation increases. At a certain angle of attack, which is between 60° and 70°, the amplitude of the side force oscillation becomes comparable to the ball’s weight. The simulated flight trajectory fluctuates. The amplitude is estimated at a few centimeters. Verf.-Referat
