Abstract

Disclosed here are airframe component assemblies including example embodiments with a root connected to an aircraft fuselage, a free section with a connection portion with holes, a slidable attachment section formed to fit between the root and the free section, and an elastomeric retention device coupled to the root and the slidable attachment section, the elastomeric retention device configured to exert a force to pull the slidable attachment toward the root.

First claim

What is claimed is:

1. A wing assembly, comprising:
a wing root connected to an aircraft fuselage, the wing root having a leading edge, a trailing edge, a protrusion forming a cut out space, the protrusion having at least two holes;
a free wing section with a bracket, the bracket formed to fit into the cut out space, wherein the bracket includes at least two holes;
a slidable wing attachment section formed to fit between the wing root and the free wing section; and
an elastomeric retention device coupled to the wing root and the slidable wing attachment section, the elastomeric retention device configured to exert a force to pull the slidable wing attachment section towards the wing root.

2. The wing assembly of claim 1 , wherein the elastomeric retention device is a coiled tension spring.

3. The wing assembly of claim 1 , wherein the wing root includes a button protrusion and the free wing section includes a button cavity configured to mate with the button protrusion.

4. The wing assembly of claim 1 , wherein the slidable wing attachment section includes two rods formed to fit into the at least two holes in the wing root and the at least two holes in the bracket.

5. The wing assembly of claim 1 , wherein the elastomeric retention device is a hydraulic tension piston.

6. The wing assembly of claim 1 , wherein the elastomeric retention device is configured to pull the slidable wing attachment section towards the leading edge of the wing root.

7. The wing assembly of claim 1 , wherein the elastomeric retention device is configured to pull the slidable wing attachment section towards the trailing edge of the wing root.

8. The wing assembly of claim 4 , wherein the bracket includes a wedge configured to force the slidable wing attachment section away from the wing root to facilitate insertion of the two rods into the at least two holes in the bracket.
