Abstract
The disclosed embodiments relate to a system for opening and closing an aircraft landing-gear compartment comprising a plurality of hatches mounted on a fairing of the aircraft. It has, in particular, main hatches with crosswise opening and at least one secondary hatch with longitudinal opening.
Claims13
1- System for opening and closing a landing-gear compartment of an aircraft comprising a plurality of hatches mounted on a fairing of the aircraft, characterized in that the system comprises main hatches with transversal opening and at least one secondary hatch with longitudinal opening.
2- System according to claim 1, characterized in that the secondary hatch comprises a closed position in which said hatch is placed in the continuity of the fairing of the aircraft and an open position in which said hatch is parallel to the fairing of the aircraft.
3- System according to claim 1, characterized in that the secondary hatch is fixed to the fairing of the aircraft by means of a hinging system giving the secondary hatch a motion of vertical translation and a combined motion of rotation and horizontal translation.
4- System according to claim 1, characterized in that the secondary hatch, during an opening process, is parallel to the flow of fluid along the aircraft.
5- System according to claim 3, characterized in that the hinge system comprises a goose-necked hinge fixed by a first rotating link to the fairing and by a second rotating link to the secondary hatch.
6- System according to claim 5, characterized in that the second rotating link comprises a plurality of ties distributed on the secondary hatch.
7- System according to claim 6, characterized in that at least one of the ties provides for a rotation of the goose-necked feature and a gradual kinematic locking of the secondary hatch.
8- System according to claim 3, characterized in that the hinge system comprises a linking element forming a stop for the closing of the front hatches.
9- System according to claim 8, characterized in that the linking element is fixed to the landing gear by a rigid link and connected to the secondary hatch by a third rotating link.
10- System according to any of the above claims, characterized in that the secondary hatch is equipped with a stiffening piece.
11- System according to claim 6, characterized in that least one tie is incorporated into the stiffener.
12- System according to claim 1, characterized in that it comprises two main hatches and one secondary hatch.
13- Aircraft characterized in that it comprises a system for opening and closing a landing-gear compartment according to claim 1.
