Criteria for Predicting Spin Susceptibility of Fighter-Type Aircraft
Abstract
An investigation was conducted to determine if there is a correlation between lateral-directional static stability characteristics and spin susceptibility. The effects of longitudinal static stability and adverse or proverse yaw were also considered. The motion of an airplane entering the high angle of attack, low speed flight regime is analyzed in six degrees of freedom. The Cn beta, dynamic, and aileron-alone divergence parameters are calculated for four aerodynamic cases. Results show that these parameters have promise as criteria for predicting spin susceptibility of fighter-type aircraft in the early stages of design and development. An airplane whose Cn beta, dynamic, and aileron-alone divergence parameters are both negative at near-stall angles of attack tends to be susceptible to spinning and an airplane with positive values for these parameters tends not to be susceptible to spinning.
