FIELD: multi-layer panels; construction of fuselage.
SUBSTANCE: proposed multi-layer panel has first skin (1) and second skin (2) with filler (4) located in between them; part of surface of filler and first and/or second skins form through passages. Located along at least two opposite sides of panel are coupling members made in form of hollow tips (3); each tip has holes for connecting the cavity of tip with through passages. Multi-layer panels of fuselage are engageable by sides located along longitudinal axis of fuselage and are interconnected by means of hollow tips which form system of drainage passages. For drainage of moisture condensed in fuselage, panels are so located that hollow tips should form system of drainage passages located along fuselage longitudinal axis.
EFFECT: enhanced efficiency of fuselage drainage; enhanced strength and reliability; reduced mass.
