Influence of tail length upon the spin-recovery characteristics of a trainer-type-airplane model

Walter J. Klinar, Thomas L. Snyder
Dec 1948

An investigation has been conducted to determine the effect of tail length on the spin and recovery characteristics of a model typical of a trainer-type airplane. The model used in the investigation was tested with two tail lengths, and the model having the shorter tail length was tested with several ventral fins installed in order to improve its recovery characteristics.
