Abstract

An aircraft includes a fuselage and a fixed flying surface having two wings, and a cradle-shaped ventral fairing at the crossover of the latter with the flying surface and provided with two longitudinal flanges climbing laterally along the fuselage and being provided with an opening for the passage with play of the corresponding wing to form a first peripheral slot around the ventral fairing and a second peripheral slot around each wing. An elongate seal is fixed to the periphery of the ventral fairing and to the periphery of each opening, so at to shut off the first and second slots, respectively. The seal includes a longitudinal elastic end lip applied, via the inner face of its free end, respectively against the fuselage or the flying surface and a longitudinal leaktightness member, carried by the inner face of the seal set back with respect to the end lip and also able to be applied against the fuselage or flying surface, respectively. The additional longitudinal leaktightness member is radially elastic bead.

Dependent claims

An aircraft comprising:

a fuselage and a fixed flying surface comprising two wings opposite one another with respect to said fuselage;
a cradle-shaped ventral fairing, fixed with play to the lower part of said fuselage, at the crossover of the latter with said flying surface and provided with two longitudinal flanges climbing laterally along said fuselage, said longitudinal flanges being provided, each, with an opening for the passage with play of the corresponding wing in such a way as to form:
a first peripheral slot around said ventral fairing, between the latter and said fuselage;
and
a second peripheral slot around each wing between the latter and the periphery of the corresponding opening;
and
an elongate seal, fixed to the periphery of said ventral fairing and to the periphery of each opening, so as to shut off said first and second slots, respectively, said seal comprising:
a longitudinal elastic end lip able to be applied, via the inner face of its free end, respectively against said fuselage or said flying surface;
and
an additional longitudinal leaktightness member, carried by the inner face of said seal set back with respect to said end lip and also able to be applied against said fuselage or said flying surface, respectively,
wherein said additional longitudinal leaktightness member is a radially elastic bead.
