Abstract: A liquid sealant applicator system that may include a liquid sealant applicator having a coupling to reversibly connect to a source of liquid sealant, a sidewall extending from the coupling and defining a sealant flow path, a flow restrictor that restricts the sealant flow path to an annular pattern of apertures in the flow restrictor, a porous matrix that fills at least a portion of the sealant flow path downstream of the flow restrictor, a matrix retainer configured to retain the porous matrix within the sealant flow path, and a fastener socket connected to the sidewall and having a distal end configured to be placed over and at least substantially enclose the head of a preselected fastener. The applicator is configured to provide a uniform application of sealant from the source of the liquid sealant to the head of the fastener enclosed by the fastener socket.

Abstract: An apparatus, system and method for isolating a controlled environment for cure process control of application and cure of one or more curable compounds to a structure. The apparatus has an end effector of an involute conformal mold having a mold body shaped to provide a shroud over an area covered with the one or more curable compounds on the structure, to isolate the area and the controlled environment. The mold body has an exterior surface, and an interior surface with a cavity profile corresponding to a desired curable compound shape. The mold body has one or more ports, and a plurality of involute channels with spiral flow paths. The involute channels include outer channel(s) having an outer path profile for regenerative heat transfer to the curable compound(s), and include inner channel(s) having an inner path profile for convective and radiative heat transfer to the curable compound(s).
