Abstract: Methods are provided by which a treatment fluid (e.g., a liquid corrosion inhibitor) may be applied onto the interior surfaces of an aircraft fuselage. The methods include (a) deploying an automated guided vehicle (AGV) comprising a carriage assembly and a robotic spray system carried by the carriage assembly within the interior of the fuselage, (b) closing the cabin door opening of the fuselage with the AGV positioned therewithin, and (c) operating the AGV so as to move within the fuselage along a longitudinal axis thereof to spray the treatment fluid onto the surfaces thereof.

Abstract: Systems and methods are provided by which a treatment fluid (e.g., a liquid corrosion inhibitor) may be applied onto the interior surfaces of an aircraft fuselage which employ an automated guided vehicle (AGV) comprising a carriage assembly and a robotic spray system carried by the carriage assembly supported by a support platform positioned laterally of an aircraft fuselage in alignment with the cabin door opening thereof. The AGV may thus be deployable through the cabin door opening of the fuselage to a deployed position within the interior of the fuselage so as to be moveable along a longitudinal axis of the fuselage to allow the robotic spray assembly to spray the treatment fluid onto interior surfaces of the fuselage. A sealing door assembly located rearwardly of the AGV which is moveable relative to a door opening in the fuselage may also be provided so as to sealingly close the door opening of the fuselage when the AGV is deployed within the interior of the fuselage.
