A plug for insertion into a blast-tube exit cavity of a gun-blast diffuser comprises a plug front surface, a plug rear surface, a plug side surface that extends between the plug front surface and the plug rear surface, a body, comprising a polyurethane foam, and a substrate, coupled to the body and comprising a conductive nonwoven fabric, impregnated with a polyurethane matrix. The plug front surface of the plug is formed by the substrate. The plug rear surface of the plug is formed by the body. The plug side surface of the plug is formed by the substrate and the body.

An assembly of a pylon and of a nacelle of an aircraft, wherein the nacelle has a structure, a visor, two centering systems and two tensioning systems. Each tensioning system comprises a first fitting, which is attached to the structure and has an engagement wall through which an orifice passes, a second fitting, which is attached to the visor, a threaded rod that is articulated on the second fitting and passes through the orifice, a spring element fitted on the threaded rod against the opposite face of the engagement wall from the second fitting, and an arresting means that blocks the spring element. Each centering system comprises a first fitting, which is attached to the structure and has a bore, and a second fitting, which is attached to the visor and bears a shaft that is accommodated in the bore.
