Abstract
A simple method for studying spin regimes in a horizontal wind tunnel is considered. The method is based on the assumption about the weak influence of the spin radius on aerodynamic characteristics. The experimental technique is analyzed, and the equipment developed and the models examined are described. The results are compared with the data obtained by traditional methods of spin studies. The effect of inertial properties of the configuration and the position of the center of mass on steady spin parameters is demonstrated. Comparative estimates of efficiency of various methods for recovery are obtained, and recommendations for improving the spin characteristics of the examined configurations are developed.
