Abstract: The invention relates to an aircraft comprising: a drainage system for condensation water formed in the aircraft between an upper zone thereof where the condensation water is formed and a lower zone where it is collected, a thermal insulation blanket (16) having two opposite faces, a first face (16a) of which is arranged facing the fuselage. The drainage system includes a drainage duct (18, 24) which extends into the upper zone along the second opposite face (16b) of the insulation blanket and which is connected to a pass-through device (30; 40) for the blanket placed beneath the upper zone. In this way, the drained condensation water passes through the blanket through the pass-through device and then is drained to the lower zone, between the first face of the blanket and the fuselage.

Abstract: An insulation device for an aircraft, comprising a blanket comprising a layer of insulation filling enclosed in a cover and having provision areas for the passage of aircraft components, these areas being devoid of insulation filling and being formed by a surface junction of two opposite faces of the cover inducing a recess in at least one face. The insulation device comprises an associated detachable complementary assembly to cover at least one of the provision areas, the assembly comprising a portion of insulation filling shaped to fit into the corresponding recess, and a retention arrangement for retaining this portion of filling. The retention arrangement is provided with a detachable arrangement for fixing the detachable complementary assembly on at least one face of the cover.
