Tapered strut with mechanical fittings

1. A composite tapered tubular assembly comprising:

a composite tapered tube extending between a first end and a second end, said tube being tapered so as to have a smaller radius (R 1 ) at the first end than a radius (R 2 ) at the second end;

a first internal annular wedge provided to be in contact with an inner surface of the tube at said first end;

a first external annular wedge provided to be in contact with an outer surface of the tube at said first end;

a first nut provided at said first end, said first nut being configured to be connected to said first internal wedge; and

a second external annular wedge provided on the outer surface of the tube;

a second internal annular wedge provided to be in contact with the inner surface of said composite tube at said second end; and

a second nut connected to an internal surface of the second external annular wedge;

wherein said second nut comprises a lip feature that contacts a face of the second internal annular wedge;

wherein said second nut has a central axis (L) and wherein said lip feature extends in a plane (P) that is perpendicular to said central axis (L).

2. The assembly of claim 1 , wherein said first nut contacts a surface of the first external annular wedge that extends in a plane (P) that is perpendicular to a central axis (L) of the first external annular wedge.

3. The assembly of claim 2 , wherein said first nut is screwed into said first internal annular wedge.

4. The assembly of claim 1 , wherein said second nut is threaded into the second external annular wedge.

5. The assembly of claim 1 , wherein an internal diameter of the second external annular wedge exceeds an external diameter of the first external annular wedge.

6. A method of making a composite tapered tubular assembly comprising:

providing a composite tapered tube extending between a first end and a second end along a longitudinal axis (L), said tube being tapered so as to have a smaller radius (R 1 ) at the first end than a radius (R 2 ) at the second end;

providing a first internal annular wedge so as to be in contact with an inner surface of the tube at said first end;

providing a first external annular wedge positioned so as to be in contact with an outer surface of the tube so that said tube is sandwiched between said first inner and external annular wedges and providing a first nut at said first end; and

connecting said first nut to said first internal wedge, said method further comprising:

providing a second external annular wedge on the outer surface of the tube and

providing a second internal annular wedge so as to be in contact with the inner surface of said composite tube so that said tube is sandwiched between said second inner and external annular wedges, and

connecting a second nut to an internal surface of the second external annular wedge;

providing a lip feature on said second nut, and contacting said lip feature with a face of the second internal annular wedge, wherein the lip feature is provided so that it extends in a plane (P) that is perpendicular to said longitudinal axis (L).

7. The method of claim 6 , further comprising connecting said first nut to a surface of said first external annular wedge that extends in a plane (P) that is perpendicular to a longitudinal axis (L) along which the tube extends.

8. The method of claim 6 , further comprising:

screwing said first nut into said first internal annular wedge.

9. The method of claim 6 further comprising:

threading said second nut into the second external annular wedge.
