Mechanical support and attachment interface for a composite lattice structure, in particular on a composite structure forming a framework of a rigid airship

A method for attaching a piece of equipment including a chord to a composite lattice structure, comprising:

• providing a composite lattice structure including:
• at least one chord in the form of a cylindrical tube;
• at least two diagonals;
• and
• at least one connection interface configured to connect the at least one chord to the at least two diagonals, the connection interface including at least one sleeve configured to surround the at least one chord about a longitudinal direction, the at least one sleeve comprising:
• at least two radially projecting sockets, each of the at least two radially projecting sockets configured to receive one end of one of the diagonals;
• a first reinforcing part extending between the two sockets, the first reinforcing part having a bore forming a first attachment point;
• and
• a second reinforcing part opposite the first reinforcing part with respect to the longitudinal direction, the second reinforcing part having a second bore forming a second attachment point;
• and
• a fastener having a half-cylinder extending along a direction, an internal diameter of the half-cylinder being equal to an external diameter of the sleeve of the at least one connection interface, the fastener having two fins extending on either side of the ends of the half-cylinder in a plane transverse to the direction, each of the two fins having a flat surface coplanar with a flat surface of the other fin, forming the same common bearing plane, each of the two fins having a bore, a distance between the bores of the two fins being equal to a distance between the bores of the at least one connection interface;
• and
• attaching the piece of equipment to the fastener.
