Abstract
A flap arrangement includes a basic body, a hinge arrangement, and a flap that by the hinge arrangement is movably held on the basic body. The hinge arrangement includes at least three bearing points spaced apart from each other and arranged on a shared hinge line, wherein two bearing points are rigidly connected to the basic body and to the flap, and wherein the remaining bearing points in each case allow local movement between the basic body and the flap in at least one first spatial direction perpendicularly to the hinge line. Thus, load-induced constraint forces between the basic body and the control surface can be prevented.
Claims18
A flap arrangement, comprising:
- a basic body,
- a hinge arrangement, and
- a flap movably held on the basic body by the hinge arrangement,
- wherein the hinge arrangement comprises at least first, second, and third points of articulation spaced apart from each other at a predetermined distance from one another and arranged on a shared hinge line such that, in an absence of a load acting on the flap arrangement, the hinge line is a straight line,
- wherein, at the first and second points of articulation, the flap is rigidly connected to the basic body such that a deformation of the flap at the first and second points of articulation is congruent to a deformation of the basic body, and
- wherein, at remaining one or more non-rigid points of articulation, in each case allow a local relative movement between the basic body and the flap in at least one first spatial direction perpendicularly to the hinge line is allowed such that the deformation of the flap at the remaining one or more non-rigid points of articulation is not congruent to the deformation of the basic body.
An aircraft, comprising at least one flap arrangement, the flap arrangement comprising:
- a basic body,
- a hinge arrangement, and
- a flap movably held on the basic body by the hinge arrangement,
- wherein the hinge arrangement comprises at least first, second, and third points of articulation spaced apart from each other and arranged on a shared hinge line such that in an absence of a load acting on the flap arrangement the hinge line is a straight line,
- wherein, at the first and second points of articulation, the flap is rigidly connected to the basic body such that a deformation of the flap at the first and second points of articulation is congruent to a deformation of the basic body, and
- wherein, at remaining one or more non-rigid points of articulation, in each case a local relative movement between the basic body and the flap in at least one first spatial direction perpendicularly to the hinge line is allowed such that the deformation of the flap at the remaining one or more non-rigid points of articulation is not congruent to the deformation of the basic body.
