ABSTRACT:
A filament dispenser (18) for a missile data link has a bobbin with end flanges (24, 26) fixedly mounted to the missile (86). A shroud (30) is spaced opposite the filament pack for frictionally engaging a ballooning filament (30) during dispensing to reduce ballooning amplitude. A second version passes the dispensed filament back through an opening (38) in the bobbin for reverse dispensing. A third version is similar to the first version and, in addition, on leaving the bobbin filament (48) passes through a relatively small diameter ring (52). In a fourth version, similar to the second version, the filament (80) passes through a constraining ring (82) located within the bobbin opening (38). In a final version the filament dispensed from a pack (92) passes around a curved end flange (90) then back over a curved surface (106) and through an opening (102) forming two balloons (109, 110) and helix elimination.
