Abstract:

This report presents the status of spin research for recent airplane designs as interpreted at the Langley Research Center of the National Aeronautics and Space Administration. Major problem areas discussed include: (1) Interpretation of results of spin-model research (2) Analytical spin studies (3) Techniques involved in obtaining measurements of various parameters in the spin (4) Effectiveness of controls during spins and recoveries (5) Influence of long noses, strakes, and canards on spin and recovery characteristics (6) Correlation of spin and recovery characteristics for recent airplane and model designs. Analyses conclusions are drawn.
