ABSTRACT:
A double-pane aircraft cabin window arrangement avoids fogging, frosting, or icing of the window without using any active pressure regulating system or other active components. An inner pane and an outer pane are held in a window seal that is mounted in a frame connected to the aircraft fuselage. An interspace is formed between the two panes and sealed by the window seal. A condensation inducing tube is connected by a hose to an adapter tube, which passes through the window seal into the window interspace. The condensation inducing tube is connected in a direct thermally conducting manner to the outer fuselage skin of the aircraft. An open end of the condensation inducing tube is arranged to receive pressurized air from the aircraft cabin interior. As the air flows through the condensation inducing tube, any condensable moisture in the air condenses out on the interior walls of the tube, so that only dry air flows into the window interspace.
