ABSTRACT:
A missile data link filament (12) dispenser (10) is located within an enclosure (20) having a single eyelet opening (26) through which the filament feeds on launch. A quantity of a damping gas having an effective density of at least about two times that of air (28) is provided within the enclosure (20). The gas serves to damp the helical motion of the filament by absorbing its rotational energy, to inhibit ballooning of the filament (12) as it is paid out from the dispenser (10).
