Abstract

A conformal sealing fixture includes an inflatable bladder (24) having a bladder body (26), a sealing surface (28), and an intake port (30). The bladder body (26) has an outer skin (32) surrounding a hollow inner volume, which is configured to expand to a rigid or semirigid structure when in an inflated state and to collapse to a flaccid structure when in a deflated state. The sealing surface (28) is configured to form a leak-tight seal against a port (20) in a component assembly (10). The intake port (30) is configured to direct a pressurizing fluid into and out of the hollow inner volume of the bladder body (26) to inflate the bladder to the inflated state and deflate the bladder body (26) to the deflated state. The bladder body (26) is configured to be positioned within a constrained space (12) in an industrial assembly (14) when the bladder body (26) is in the deflated state and is configured to conform to a geometry of the constrained space (12) when the bladder body (26) is in the inflated state, such that when the bladder body (26) is in the inflated state, the sealing surface (28) engages with the port (20) in the component assembly (10) to form a leak-tight seal.
