Cable-Operated Zero-Impedance Decoupler (COZID)

Abstract

The ability of the helicopter to carry heavy, oversized cargo external to the airframe is a major contributor to the vehicle's operational flexibility. This capability permits the rapid transfer of an almost unlimited variety of materiel without the imposition of severe restrictions on materiel size, shape or weight distribution. One factor which imposes a potential limitation on this flexibility is the generation of high airframe/external load vibration levels caused by resonance or near resonance of the helicopter/sling/ external cargo dynamic system with rotor induced forces. Alleviation of this condition, which is generally referred to as vertical bounce, is the ultimate objective of the Cable-Operated Zero-Impedance Decoupler (COZID) development effort described in the report.
