Abstract:

An investigation was conducted in the Propulsion Wind Tunnel 16T to obtain static stability characteristics of the MK-82 and MK-84 with air inflatable Ballutes registered trademark and selected fin configurations. The MK-82 model was 0.442 scale and had slotted fins with 12.5-deg spin wedges. The MK-84 model was 0.264 scale and had two sets of cambered fins. Each model was equipped with a fuse, lugs, and a lanyard pack. The tests were conducted for various model and Ballute roll orientations at Mach numbers from 0.6 to 1.4 for angles of attack up to 20 deg and Reynolds numbers from 510,000 to 680,000 based on the centerbody maximum diameter. Model and Ballute roll orientation had only small effects on the normal-force, axial-force, and pitching-moment coefficients. Installing the Ballute with the Ballute inlets in the wake of the fins decreased the rolling-moment and yawing-moment coefficients and increased the side-force coefficient.
