Installation system and method for installing a self-supporting truss structure

An installation system for installing a self-supporting truss structure having a plurality of interconnected truss elements on a fuselage of an aircraft, wherein the truss structure has radially outer closed truss nodes and radially inner releasable connecting nodes, the installation system comprising:

• a mobile carrying device, which can be moved on a floor of the fuselage and has an upper receptacle,
• a stand for temporarily holding the truss elements in predetermined positions relative to one another, and
• a movement device, which is arranged on the upper receptacle and holds the stand in a position that can be set relative to the upper receptacle,
• wherein the movement device is configured to hold the stand in a transport position and in any desired installation position, wherein the stand is further away from the upper receptacle in installation positions than in the transport position,
• wherein the installation system is configured, when the stand is in the transport position, to move the mobile carrying device on the floor into a predetermined position within the fuselage and to lock it there, to move the stand into a suitable installation position by means of the movement device, and to lock at least one connecting node by means of a drive arranged on the stand.
