An investigation was made to determine the effects of vertical-tail size and length and of fuselage shape and length on the lateral static stability characteristics of a mode with wing and vertical tails having the quarter-chord lines swept back 45 degrees. The results indicate that the directional instability of the various isolated fuselages was about two-thirds as large as that predicted by classical theory.
