Comparison of Vee-Type and Conventional Tail Surfaces in Combinations with Fuselage and Wing in the Variable-Density Tunnel

Abstract

Measurements of pitching and yawing moments of a Vee-type and of a conventional type empennage were made in the presence of wing and wing-fuselage to determine their moments. Vee-tail with a dihedral angle of 35.3 degrees was 71% as effective in pitching as conventional tail, and its ratio of yaw moment to pitch moment was 0.3. Fuselage interference reduced measured moments 15 to 25% of calculated values.
