High Viscosity Liquid Payload Yawsonde Data for Small Launch Yaws

Abstract

Eight projectiles filled with high viscosity liquid payloads were tested at Wallops Island, Virginia, on 16 October 1978. These shells were instrumented with fuze-configured yawsondes and were filled with liquid payloads whose viscosities were three to five orders of magnitude larger than that of water. Unstable flights occurred for launch yaws as small as 2.5 degrees for the high viscosity liquid payloads. This type of flight instability cannot be predicted by available liquid-filled projectile theories and represents a hazard to new payload concepts that may employ such liquids.
