Abstract
Official abstract text for this publication.
A composite tube assembly may comprise a composite tube comprising a radially outer surface having a variable diameter portion comprising a first frustoconical portion and a second frustoconical portion, a locking wedge disposed at least partially around a circumference of the first frustoconical portion, a locking collar nut disposed at least partially around a circumference of the locking wedge, and an end fitting disposed at least partially around a circumference of the second frustoconical portion, wherein the end fitting is coupled to the locking collar nut. A diameter of the composite tube, at an interface between the first frustoconical portion and the second frustoconical portion, may be a maximum diameter value with respect to the first frustoconical portion and may be a maximum diameter value with respect to the second frustoconical portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A composite tube assembly comprising: a composite tube comprising a radially outer surface having a variable diameter portion comprising a first frustoconical portion and a second frustoconical portion, wherein a diameter of the composite tube at an interface between the first frustoconical portion and the second frustoconical portion is a maximum diameter value with respect to the first frustoconical portion and is a maximum diameter value with respect to the second frustoconical portion; a locking wedge disposed at least partially around a circumference of the first frustoconical portion; a locking collar nut disposed at least partially around a circumference of the locking wedge; an end fitting disposed at least partially around a circumference of the second frustoconical portion, wherein the end fitting is coupled to the locking collar nut; a locking key in contact with the locking collar nut and the end fitting; and a jam nut threadedly engaged to the end fitting. 2. The composite tube assembly of claim 1 , wherein the end fitting is threadedly engaged with the locking collar nut. 3. The composite tube assembly of claim 1 , wherein the locking wedge comprises a plurality of subcomponents. 4. The composite tube assembly of claim 1 , wherein an outer surface of the first frustoconical portion and an outer surface of the second frustoconical portion are nanocoated. 5. The composite tube assembly of claim 1 , wherein the locking wedge comprises one single integral piece. 6. The composite tube assembly of claim 1 , wherein the locking key is disposed in a keyway, the keyway being disposed in the end fitting.
