Test of Materiel Division Barrage Balloon Model With Three Different Tail Arrangements
Abstract
Tests were made to determine the best of three different tail arangements for a barrage balloon. The first arrangement consisted of two horizontal and two vertical fins. This arrangement was unstable about the center of buoyancy. The second tail arrangement, consisting of two different horizontal and vertical fins, wsa longitudinally and directionally stable for angles of pitch or yaw from 0 to + or - 20 deg. Higher angles were not tested. The third tail arrangement consisted of two horizontal, one upper, and two lower fins. The only difference between this condition and the previous one was the additional fin on the bottom. This change had no appreciable effect on the longitudinal stability but increased the directional stability about 40$. The drag was also increased about 20%.
