ABSTRACT:
A decoy system is disclosed characterized by use of a rotating towline spool having an axial bore therethrough adapted to receive a pyrotechnic charge adjacent one end thereof and communicate gas pressure upon detonation of the charge to the decoy to deploy the decoy from an aircraft. Pyrotechnic charges for both decoy ejection and towline cutting may be externally loaded into the system without the need to disassemble the decoy system and the use of the axial bore through the spool results in desired space economies. The interior of the decoy cannister is provided with plural guide rails and contoured guide rollers which facilitate ejection of the decoy from the cannister in directions even or perpendicular to the airstream of the aircraft. Towline spool and decoy terminations and a method of fabricating the same are disclosed which yield sufficient strength to withstand peak tensile forces exerted during initial acceleration and subsequent maximum pay out of the decoy.
