Abstract

A fairing arrangement for an aircraft high-lift mechanism, the high-lift mechanism including a flap arranged at an aircraft wing trailing edge and a mounting and guiding mechanism for the flap. The fairing arrangement includes a flap side fairing unit and a wing side fairing unit. The flap side fairing unit includes a flap side fairing covering an aft part of the mounting and guiding mechanism and a flap side fairing mount mounting the flap side fairing to the flap. The wing side fairing unit includes a wing side fairing covering a forward part of the mounting and guiding mechanism and a wing side fairing mount mounting the wing side fairing to the wing. The wing side fairing mount is configured to connect the wing side fairing movably to the wing such that the wing side fairing is rotatable around an axis directed at least partially in a vertical direction.

First claim

The invention claimed is:

1. A fairing arrangement for a high-lift mechanism of an aircraft, wherein the high-lift mechanism includes a flap to be arranged at a trailing edge of an aircraft wing and a mounting and guiding mechanism for the flap,
the fairing arrangement comprising a flap side fairing unit and a wing side fairing unit,
the flap side fairing unit comprising a flap side fairing for covering an aft part of the mounting and guiding mechanism and a flap side fairing mount for mounting the flap side fairing to the flap,
the wing side fairing unit comprising a wing side fairing for covering a forward part of the mounting and guiding mechanism and a wing side fairing mount for mounting the wing side fairing to the wing,
wherein the wing side fairing mount is configured to connect the wing side fairing movably to the wing such that the wing side fairing is rotatable around an axis directed at least partially in a vertical direction.

2. The fairing arrangement according to claim 1 , wherein the wing side fairing mount comprises a forward connecting mechanism configured to connect a forward part of the wing side fairing rotatably with at least one or with two degrees of freedom to the mounting and guiding mechanism.

3. The fairing arrangement according to claim 2 , wherein the forward connecting mechanism includes a multi-axis bearing or a spherical bearing.

4. The fairing arrangement according to claim 1 , wherein the wing side fairing mount comprises a rearward connecting mechanism configured to connect a rearward part of the wing side fairing such that the wing side fairing is movable in a spanwise direction.

5. The fairing arrangement according to claim 4 ,
wherein the wing side fairing mount comprises a forward connecting mechanism configured to connect a forward part of the wing side fairing rotatably with at least one or with two degrees of freedom to the mounting and guiding mechanism, and
wherein the rearward connecting mechanism includes at least one or several of the group consisting of:
a swing strut,
a pair of parallel swing struts,
a tensile means, a cable,
an arrangement of a track and rollers or sliders,
an upper track and roller or slider arrangement,
a lower track and roller or slider arrangement,
a track curved around the rotation axis of the forward connecting mechanism in combination with a set of rollers or sliders running on the curved track, and
a linear bearing.

6. The fairing arrangement according to claim 1 , wherein a forward end portion of the flap side fairing engages into a rearward end portion of the wing side fairing to allow a telescopic and rotational relative movement of said wing side fairing and said flap side fairing.

7. The fairing arrangement according to claim 1 ,
wherein a fixed front fairing unit is configured to be rigidly fixed to the wing, and
wherein the wing side fairing unit is configured as an intermediate movable wing side fairing unit arranged between fixed front fairing unit and the flap side fairing unit.

8. A high-lift system for an aircraft, comprising
a high-lift mechanism including a flap to be arranged at a trailing edge of an aircraft wing and a mounting and guiding mechanism for the flap, and
a fairing arrangement according to claim 1 .

9. An aircraft wing comprising a high-lift system according to claim 8 .

10. An aircraft, comprising a wing according to claim 9 .

11. An aircraft, comprising a high-lift system according to claim 8 .

12. An aircraft wing comprising a fairing arrangement according to claim 1 .

13. An aircraft, comprising a wing according to claim 12 .

14. An aircraft, comprising a fairing arrangement according to claim 1 .
