Effect of horizontal tail on low-speed static lateral stability characteristics of a model having 45 degree sweptback wing and tail surfaces

An investigation has been conducted in the Langley stability tunnel to determine the effects of changes in horizontal-tail size and location on the static lateral stability characteristics of a complete model with wing and tail surfaces having the quarter-chord line swept back 45 degrees. Available procedures, based on analyses of unswept-tail configurations, for predicting the effect of the horizontal tail on directional stability, were found to be unreliable when applied to swept-tail configurations.
