Wind Tunnel Magnus Testing of a Canted Fin or Self-Rotating Configuration
Abstract
A source of error in the wind tunnel measurement of Magnus forces and moments on a self-rotating configuration has been detected, and means of overcoming the error are presented. The error is due to a normal force interaction brought about by the roll of the angle of attack plane which in turn is due to a small yaw angle of the model at zero angle of attack. The error is not a balance interaction error. The error can completely mask the true Magnus characteristics and can lead the experimenter to wrong conclusions. Although a computed correction may be made to existing data, the best method of eliminating the error is to obtain balance readings with and without spin at each angle of attack of interest.
