Vertical Tail Design for Base-line Configuration of Military Combat Aircraft

Simple statistical correlations are evolved to choose size, relative location and geometry of vertical tail for base-line design configuration of military combat airplanes. These correlations reveal that the vertical tail size is proportional to fuselage volume. They further bring out, that structural aspect ratio gradually increases with increase in thickness to chord ration in the lower range, and tends to attain an asymptotic value in the higher range, clearly indicating that gains in structural aspect ration are not commensurate with increase in thickness to chord ratio in the higher range. taper ratio is found to be proportional to quarter chord sweep.
