A device for determining the temperature of a tubular strand conveyed out of an extrusion device includes at least one temperature sensor configured to measure a first temperature of an outside of the tubular strand at a first position of the tubular strand. An evaluation apparatus further included and configured to compare the first temperature with a second temperature of the outside of the tubular strand at a second position of the tubular strand and determine at least one of a temperature within the tubular strand or a temperature on the inside of the tubular strand at a position of the tubular strand based on the comparison of the first and second temperature.

A device for measuring a strand that is tubular includes a first radiation source to emit terahertz radiation in a first measurement region from an inside onto an inner surface of the strand. A first radiation receiver receives terahertz radiation reflected by the strand in a second measurement region. A first evaluation apparatus determines at least one geometric parameter of the strand in the first measurement region. A second radiation source emits terahertz radiation in the second measurement region from an outside onto an outer surface of the strand. A second radiation receiver receives terahertz radiation reflected by the strand in the second measurement region. A second evaluation apparatus determines at least one geometric parameter of the strand in the second measurement region. A third evaluation apparatus determines a change in the at least one geometric parameter of the strand between the first and second measurement regions.

A fuselage structure comprises a plurality of elements that in longitudinal direction are interconnected by weld joints; a plurality of circumferential ribs that are connected to the plurality of elements and that extend so as to be substantially perpendicular in relation to the longitudinal direction of the elements; and a plurality of clips that are arranged between the elements and the ribs such that said clips do not cover the respective weld joints.
