Problems solved by technology

[0005] This embodiment is not entirely satisfactory because it is relatively difficult to determine the most suitable profile of the load-bearing structure 10 according to the orientation of the load-bearing structure 10 in the fluid flow
In addition, when the load-bearing structure 10 is part of an aircraft, different actuators 26 can lead to a significant increase in the weight carried
Finally, actuators and drive systems tend to add to the cost of manufacturing and maintaining the load-bearing structure 10

Embodiment Construction

[0036] exist figure 2 Shown in a kind of aircraft 30, it comprises fuselage 32, is placed on the wing 34 of fuselage 32 both sides, is positioned at the vertical empennage 36 of fuselage 32 rear parts and is placed on two sides of vertical empennage 36 Horizontal tail 38.

[0037] according to figure 2 , image 3 and Figure 4 In the embodiment shown in , the wing 34, the horizontal stabilizer 38 and the vertical stabilizer 36 each comprise a fixed portion 40 and at least one movable portion 42 (referred to as a flap or elevator as the case may be) located in an extension of the fixed portion 40. ).

[0038] In flight, the fixed part 40 and the movable part 42 are located in the airflow 44 . The fixed part 40 and the movable part 42 form two different load-bearing structures 46, 46' (such as image 3 and Figure 4 shown), or the fixed part 40 and the movable part 42 form a single load-carrying structure 46 (as Figure 9 shown).

[0039] Although the invention is des...

Abstract

The invention relates to a supporting structure (46) which is positioned in a fluid flow (44) and characterised in that it is configured to be elastically deformed, on at least one portion of the supporting structure (46), between a first idle state in the absence of external stress and a second deformed state in the presence of external stresses caused by the fluid flow (44) due to a change in the orientation of the supporting structure (46) and / or the fluid flow (44). The invention also relates to an aircraft comprising at least one such supporting structure (46).

Description

technical field [0001] The application relates to a load-bearing structure with a passive adaptive profile Background technique [0002] according to figure 1 In the known embodiment shown, the load-bearing structure 10 located in the fluid flow comprises a first wall 12 in contact with the fluid flow, a second wall 14 in contact with the fluid flow, a frame connecting the first wall 12 and the second wall 14 16, said first wall 12 and second wall 14 are connected upstream at the leading edge 18 and downstream at the trailing edge 20. [0003] The frame 16 comprises a number of segments 22.1 to 22.7 joined end to end from the leading edge 18 to the trailing edge 20, the segments being connected two by two by hinges 24 each having a hinge substantially parallel to either the leading edge 18 or the trailing edge 20. pivot. Thus, each first segment located downstream of the second segment can freely pivot in both pivot directions relative to the second segment about the pivo...
