Stabilization of Externally Slung Helicopter Loads

Abstract

Use is made of experimental data and theoretical analyses to understand why load carrying speed is limited, and an attempt is made to identify promising stabilization concepts and to determine their capability to extend carrying speed. This effort is concentrated on the 8-by-8-by-20-foot cargo container; however, implications relating to other loads are given. An attempt is made to select the appropriate combination of analysis techniques that will yield a practical solution to the problem. The motions of this load are modeled, and this model is used in an analysis of stabilization systems designed to extend the carrying speed limitations. Several stabilization concepts are explored that show promise of extending carrying speed to 200 knots.
