Device for attaching a lift member to the fuselage of an aircraft
View Patent ↗The disclosed embodiments relate to an aircraft equipped with at least one device for attaching a lift member to the fuselage which includes elastic articulations whose rigidity in translation and in rotation can be adjusted axially, vertically, and transversely. An airfoil may be connected to the body of the fuselage by these elastic articulations.
1. A fixed wing aircraft, comprising:
a fuselage having a longitudinal axis (X), a transverse axis (Y) and a vertical axis (Z);
an airfoil comprising two fixed wings and a central casing;
at least one laminated elastic link through which the airfoil is fastened to the fuselage, wherein the at least one laminated elastic link has a longitudinal axis (A), and the at least one laminated elastic link secures the airfoil to the fuselage in a configuration in which the longitudinal axis (A) of the at least one laminated elastic link extends along the transverse axis (Y) of the fuselage and provides translational movement between the airfoil and fuselage in the direction of the transverse axis (Y) of the fuselage; and
wherein the at least one laminated elastic link is comprised of precompressed elastomer between two concentric tubes.
2. The aircraft of claim 1 , wherein the at least one laminated elastic link is comprised of at least one intermediate sheet in a bulk elastomer.
3. The aircraft of claim 1 , wherein the at least one laminated elastic link is further configured to provide rotational movement in a direction around the longitudinal axis (X) of the aircraft.
4. The aircraft of claim 1 , wherein the at least one laminated elastic link is further configured to be essentially immobile in the vertical axis (Z) direction of the aircraft.
5. The aircraft of claim 1 , wherein an upper lateral flange of the central airfoil casing is fastened to a lateral wall of a central section of the fuselage by a plurality of laminated elastic links.
6. The aircraft according to claim 1 , wherein a plurality of elastic links join right and left flanks of the fuselage to right and left wings of the airfoil, respectively.
7. The aircraft according to claim 1 , wherein the airfoil is fastened to a lower part of the fuselage.
8. The aircraft according to claim 7 , wherein a plurality of elastic links join a central longitudinal beam of the fuselage to the central casing of the airfoil.
9. The aircraft according to claim 1 , wherein the airfoil is fastened to an upper part of the fuselage.
10. The aircraft according to claim 1 , wherein the airfoil comprises a monobloc.
11. The aircraft according to claim 1 , wherein the airfoil is a horizontal fin of said aircraft.
