Abstract
The invention relates to an opening system () for an auxiliary door () of an airplane in a fuselage (), the door and the fuselage having skins in the extension of one another. In one exemplary embodiment, the system () includes a framing lintel () integrated into the fuselage, an upper beam (S) of the door structure arranged opposite the lintel (), and a set of three lever links (A,B,C). Each link is connected, on the one hand, to the lintel () by a lever articulation () fixed relative to the fuselage () and, on the other hand, to the upper beam (S) by a lever articulation () mobile with the door (), the articulations () being connected respectively to the lintel () and to the upper beam (S) by fittings (). The set of links includes two types of link mounted alternately, in which the mobile articulation () remains positioned respectively close to the fuselage skin () and further from this skin (), the articulations () of two adjacent levers (A,B;B,C) forming an evolving quadrilateral.
