Abstract:

Wind tunnel tests at Mach numbers from 0.55 to 1.30 and angles of attack from -4 to 20 deg were conducted on a 0.18-scale model of the M-117 Bomb with seven tail fin configurations to determine the static stability characteristics of the bomb. The seven tail fin configurations consisted of the M131A1, MAU 103B, and five variations of the MAU 103B fin. The five variations were represented by changes in fin span, chord length, and planform shape. The stability characteristics of the seven tail fin configurations were compared on the basis of neutral-point location with respect to the center-of-gravity location. A suitable fin configuration was found that was stable throughout the range of conditions tested.
