Sealing device for a flap track in a belly fairing of an aircraft for a flap-actuating shaft
Sealing device for the flap track for the flap-actuating shaft, in the belly fairing of an aircraft, with a top hollow body 1 and a bottom hollow body 7 which are flexibly compressible, each comprising at least one interior chamber 2, 8 with open sides 2 a, 2 b , a wall 3, 9 with respective external contact surfaces 3 a which are in flexible contact with each other, the outer surfaces 4 a, 10 a of the front walls 4, 10 of the hollow bodies 1, 7 jointly forming an outer sealing surface 11 which covers the flap track 19 , said hollow bodies 1,7 having jointly a vertical compression flexibility such that the contact surfaces 3 a, 9 a retract around the actuating shaft 20 , the interior chambers 2, 8 extending between the front walls 4, 10 and rear walls 5, 11 of the hollow bodies 2, 7.
1. Sealing device for a flap track in a belly fairing for an actuating shaft of a flap of an aircraft the actuating shaft, the actuating shaft being capable of moving from a first end to a second end of the flap track, the device comprising
a flexibly compressible top body comprising
at least one upper inner chamber with open sides and delimited at the bottom by a bottom wall with an lower outer contact surface,
a front wall with an upper outer surface which covers at least a first part of the flap track;
a rear wall,
a top wall; and
a flexibly compressible bottom body comprising
at least one lower inner chamber with open sides and delimited at the top by a top wall with an upper outer contact surface;
a front wall with a lower outer surface which covers at least a second part of the flap track;
a rear wall;
a bottom wall;
said contact surfaces being in flexible contact with each other;
the outer surfaces of the front walls of the hollow bodies having extensions such that they jointly form an outer sealing surface which can cover the flap track;
said hollow bodies jointly having a vertical compression flexibility such that the contact surfaces retract around the actuating shaft; and
the inner chambers extending between said front walls and rear walls.
2. Sealing device according to claim 1 , wherein the top hollow body comprises top attaching means which mountable on a top area of a panel crossed by the flap track, and wherein the bottom hollow body comprises bottom attaching means which are mountable at a bottom area of the panel crossed by the flap track.
3. Sealing device according to claim 2 , wherein the top attaching means comprise a top “L”-shaped profile joined to the top wall of the top hollow body by one of its branches.
4. Sealing device according to claim 3 , wherein the top profile is arranged such that the branch not joined to the top wall forms with its front surface a continuation of the upper outer surface.
5. Sealing device according to claim 2 , wherein the bottom attaching means comprise a bottom “L”-shaped profile joined to the bottom wall of the bottom hollow body by one of its branches.
6. Sealing device according to claim 5 , wherein the top metal profile is arranged such that the branch which is not joined to the bottom wall forms with its front surface a continuation of the upper outer surface.
7. Sealing device according to claim 1 , wherein the top body comprises a plurality of horizontally superimposed upper chambers formed by means of partitions which extend between the front wall and the rear wall of the top hollow body.
8. Sealing device according to claim 1 , wherein the bottom body comprises a plurality of horizontally superimposed lower chambers formed by means of partitions which extend between the front wall and the rear wall of the bottom hollow body.
9. Sealing device according to claim 1 , wherein the top body comprises a plurality of longitudinal ribs being parallel to each other, which emerge towards the inside of the upper chamber from at least one of the front wall and the rear wall of the top hollow body.
10. Sealing device according to claim 1 , wherein the bottom body comprises a plurality of longitudinal ribs being parallel to each other, which emerge towards the inside of the lower chamber from at least one of the front wall and the rear wall of the bottom hollow body.
