Abstract:
A sealant containment assembly is configured to bound at least a portion of a fastener pattern between at least two components, such as components used to form at least a portion of an aircraft. The sealant containment assembly includes at least one sealant containment member that is configured to sealingly engage peripheral portions of components. The sealant containment member(s) is configured to form a sealing chamber around at least a portion of the fastener pattern. Fluid sealant is configured to flow into the sealing chamber and cure to seal fasteners within the fastener pattern that connect the components together.
Abstract:
One example of the present disclosure relates to a daubing device for applying viscous material to a fastener. The daubing device comprises a housing comprising a first internal face and a second internal face, separated from the first internal face by a longitudinal distance L. The daubing device further comprises a dispenser between the first internal face and the second internal face of the housing. The dispenser comprises a flexible wall. The daubing device also comprises a pressure-application device between the dispenser and the second internal face of the housing.

Abstract:
A method of applying a viscous material to a fastener comprises aligning a nozzle relative to the fastener by engaging an aligner with the fastener. Engaging the aligner with the fastener comprises positioning the aligner over the fastener and advancing a biasing tube toward the fastener to establish contact between the aligner and a structure to partially retract the aligner into the biasing tube until a plurality of surfaces of the aligner contacts one or more outer surfaces of the fastener. A flexible wall of a dispenser bellows is deflected by expanding a pressure-application device, which is configured to apply pressure on the flexible wall of the dispenser bellows, wherein the dispenser bellows is in fluid communication with the nozzle. The viscous material is expelled from the dispenser bellows responsive to deforming the flexible wall.
