Abstract
An apparatus comprising an inner ferrule and an outer ferrule. The inner ferrule comprises a plurality of engagement sections that define a plurality of gaps between the plurality of engagement sections. The outer ferrule is disposed around at least a portion of the inner ferrule. The outer ferrule comprises an engagement area mechanically joined to the plurality of engagement sections to join the inner ferrule to the outer ferrule.
Claims25
An apparatus comprising:
- an inner ferrule comprising a plurality of engagement sections that define a plurality of gaps between the plurality of engagement sections;
- and
- an outer ferrule disposed around at least a portion of the inner ferrule and comprising an engagement area mechanically joined to the plurality of engagement sections to join the inner ferrule to the outer ferrule.
An apparatus comprising:
- an inner ferrule;
- an intermediate ferrule mechanically joined to the inner ferrule such that the intermediate ferrule is disposed around at least a portion of the inner ferrule, the intermediate ferrule comprising a plurality of engagement sections;
- and
- an outer ferrule comprising an engagement area mechanically joined to the plurality of engagement sections such that the outer ferrule is disposed around at least a portion of the intermediate ferrule.
1 more element
A method comprising:
- joining an outer duct to an outer ferrule;
- and
- joining, mechanically, a plurality of engagement sections of an inner ferrule to an engagement area of the outer ferrule such that the outer ferrule is disposed around at least a portion of the inner ferrule.
A method for moving fuel through a duct system in an aircraft, the method comprising:
- moving the fuel through an inner duct that is joined with an outer duct through a joining of an inner ferrule attached to the inner duct and an outer ferrule attached to the outer duct;
- and
- capturing a leakage from the fuel flowing through the inner duct within a region that is formed between the inner duct and the outer duct by a plurality of engagement sections of the inner ferrule that protrude radially outward from the inner ferrule and that define a plurality of gaps between the plurality of engagement sections.
